• How to safely reboot via First Boot script

  - by unixman

  With the cost and performance benefits of the SPARC T4 and SPARC T5 systems undeniably validated, the banking sector is actively moving to Solaris 11.  I was recently asked to help a banking customer of ours look at migrating some of their Solaris 10 logic over to Solaris 11.  While we've introduced a number of holistic improvements in Solaris 11, in terms of how we ease long-term software lifecycle management, it is important to appreciate that customers may not be able to move all of their Solaris 10 scripts and procedures at once; there are years of scripts that reflect fine-tuned requirements of proprietary banking software that gets layered on top of the operating system. One of these requirements is to go through a cycle of reboots, after the system is installed, in order to ensure appropriate software dependencies and various configuration files are in-place. While Solaris 10 introduced a facility that aids here, namely SMF, many of our customers simply haven't yet taken the time to take advantage of this - proceeding with logic that, while functional, without further analysis has an appearance of not being optimal in terms of taking advantage of all the niceties bundled in Solaris 11 at no extra cost. When looking at Solaris 11, we recognize that one of the vehicles that bridges the gap between getting the operating system image payload delivered, and the customized banking software installed, is a notion of a First Boot script.  I had a working example of this at one of the Oracle OpenWorld sessions a few years ago - we've since improved our documentation and have introduced sections where this is described in better detail.   If you're looking at this for the first time and you've not worked with IPS and SMF previously, you might get the sense that the tasks are daunting.   There is a set of technologies involved that are jointly engineered in order to make the process reliable, predictable and extensible. As you go down the path of writing your first boot script, you'll be faced with a need to wrap it into a SMF service and then packaged into a IPS package. The IPS package would then need to be placed onto your IPS repository, in order to subsequently be made available to all of your AI (Automated Install) clients (i.e. the systems that you're installing Solaris and your software onto).     With this blog post, I wanted to create a single place that outlines the entire process (simplistically), and provide a hint of how a good old "at" command may make the requirement of forcing an initial reboot handy. The syntax and references to commands here is based on running this on a version of Solaris 11 that has been updated since its initial release in 2011 (i.e. I am writing this on Solaris 11.1) Assuming you've built an AI server (see this How To article for an example), you might be asking yourself: "Ok, I've got some logic that I need executed AFTER Solaris is deployed and I need my own little script that would make that happen. How do I go about hooking that script into the Solaris 11 AI framework?"  You might start here, in Chapter 13 of the "Installing Oracle Solaris 11.1 Systems" guide, which talks about "Running a Custom Script During First Boot".  And as you do, you'll be confronted with command that might be unfamiliar to you if you're new to Solaris 11, like our dear new friend: svcbundle svcbundle is an aide to creating manifests and profiles.  It is awesome, but don't let its awesomeness overwhelm you. (See this How To article by my colleague Glynn Foster for a nice working example).  In order to get your script's logic integrated into the Solaris 11 deployment process, you need to wrap your (shell) script into 2 manifests -  a SMF service manifest and a IPS package manifest.  ....and if you're new to XML, well then -- buckle up We have some examples of small first boot scripts shown here, as templates to build upon. Necessary structure of the script, particularly in leveraging SMF interfaces, is key. I won't go into that here as that is covered nicely in the doc link above.    Let's say your script ends up looking like this (btw: if things appear to be cut-off in your browser, just select them, copy and paste into your editor and it'll be grabbed - the source gets captured eventhough the browser may not render it "correctly" - ah, computers). #!/bin/sh # Load SMF shell support definitions . /lib/svc/share/smf_include.sh # If nothing to do, exit with temporary disable completed=`svcprop -p config/completed site/first-boot-script-svc:default` [ "${completed}" = "true" ] && \ smf_method_exit $SMF_EXIT_TEMP_DISABLE completed "Configuration completed" # Obtain the active BE name from beadm: The active BE on reboot has an R in # the third column of 'beadm list' output. Its name is in column one. bename=`beadm list -Hd|nawk -F ';' '$3 ~ /R/ {print $1}'` beadm create ${bename}.orig echo "Original boot environment saved as ${bename}.orig" # ---- Place your one-time configuration tasks here ---- # For example, if you have to pull some files from your own pre-existing system: /usr/bin/wget -P /var/tmp/ $PULL_DOWN_ADDITIONAL_SCRIPTS_FROM_A_CORPORATE_SYSTEM /usr/bin/chmod 755 /var/tmp/$SCRIPTS_THAT_GOT_PULLED_DOWN_IN_STEP_ABOVE # Clearly the above 2 lines represent some logic that you'd have to customize to fit your needs. # # Perhaps additional things you may want to do here might be of use, like # (gasp!) configuring ssh server for root login and X11 forwarding (for testing), and the like... # # Oh and by the way, after we're done executing all of our proprietary scripts we need to reboot # the system in accordance with our operational software requirements to ensure all layered bits # get initialized properly and pull-in their own modules and components in the right sequence, # subsequently. # We need to set a "time bomb" reboot, that would take place upon completion of this script. # We already know that *this* script depends on multi-user-server SMF milestone, so it should be # safe for us to schedule a reboot for 5 minutes from now. The "at" job get scheduled in the queue # while our little script continues thru the rest of the logic. /usr/bin/at now + 5 minutes <<REBOOT /usr/bin/sync /usr/sbin/reboot REBOOT # ---- End of your customizations ---- # Record that this script's work is done svccfg -s site/first-boot-script-svc:default setprop config/completed = true svcadm refresh site/first-boot-script-svc:default smf_method_exit $SMF_EXIT_TEMP_DISABLE method_completed "Configuration completed"  ...and you're happy with it and are ready to move on. Where do you go and what do you do? The next step is creating the IPS package for your script. Since running the logic of your script constitutes a service, you need to create a service manifest. This is described here, in the middle of Chapter 13 of "Creating an IPS package for the script and service".  Assuming the name of your shell script is first-boot-script.sh, you could end up doing the following: $ cd some_working_directory_for_this_project$ mkdir -p proto/lib/svc/manifest/site$ mkdir -p proto/opt/site $ cp first-boot-script.sh proto/opt/site  Then you would create the service manifest  file like so: $ svcbundle -s service-name=site/first-boot-script-svc \ -s start-method=/opt/site/first-boot-script.sh \ -s instance-property=config:completed:boolean:false -o \ first-boot-script-svc-manifest.xml   ...as described here, and place it into the directory hierarchy above. But before you place it into the directory, make sure to inspect the manifest and adjust the appropriate service dependencies.  That is to say, you want to properly specify what milestone should be reached before your service runs.  There's a <dependency> section that looks like this, before you modify it: <dependency restart_on="none" type="service" name="multi_user_dependency" grouping="require_all"> <service_fmri value="svc:/milestone/multi-user"/>  </dependency>  So if you'd like to have your service run AFTER the multi-user-server milestone has been reached (i.e. later, as multi-user-server has more dependencies then multi-user and our intent to reboot the system may have significant ramifications if done prematurely), you would modify that section to read:  <dependency restart_on="none" type="service" name="multi_user_server_dependency" grouping="require_all"> <service_fmri value="svc:/milestone/multi-user-server"/>  </dependency> Save the file and validate it: $ svccfg validate first-boot-script-svc-manifest.xml Assuming there are no errors returned, copy the file over into the directory hierarchy: $ cp first-boot-script-svc-manifest.xml proto/lib/svc/manifest/site Now that we've created the service manifest (.xml), create the package manifest (.p5m) file named: first-boot-script.p5m.  Populate it as follows: set name=pkg.fmri value=first-boot-script-AT-1-DOT-0,5.11-0 set name=pkg.summary value="AI first-boot script" set name=pkg.description value="Script that runs at first boot after AI installation" set name=info.classification value=\ "org.opensolaris.category.2008:System/Administration and Configuration" file lib/svc/manifest/site/first-boot-script-svc-manifest.xml \ path=lib/svc/manifest/site/first-boot-script-svc-manifest.xml owner=root \ group=sys mode=0444 dir path=opt/site owner=root group=sys mode=0755 file opt/site/first-boot-script.sh path=opt/site/first-boot-script.sh \ owner=root group=sys mode=0555 Now we are going to publish this package into a IPS repository. If you don't have one yet, don't worry. You have 2 choices: You can either  publish this package into your mirror of the Oracle Solaris IPS repo or create your own customized repo.  The best practice is to create your own customized repo, leaving your mirror of the Oracle Solaris IPS repo untouched.  From this point, you have 2 choices as well - you can either create a repo that will be accessible by your clients via HTTP or via NFS.  Since HTTP is how the default Solaris repo is accessed, we'll go with HTTP for your own IPS repo.   This nice and comprehensive How To by Albert White describes how to create multiple internal IPS repos for Solaris 11. We'll zero in on the basic elements for our needs here: We'll create the IPS repo directory structure hanging off a separate ZFS file system, and we'll tie it into an instance of pkg.depotd. We do this because we want our IPS repo to be accessible to our AI clients through HTTP, and the pkg.depotd SMF service bundled in Solaris 11 can help us do this. We proceed as follows: # zfs create rpool/export/MyIPSrepo # pkgrepo create /export/MyIPSrepo # svccfg -s pkg/server add MyIPSrepo # svccfg -s pkg/server:MyIPSrepo addpg pkg application # svccfg -s pkg/server:MyIPSrepo setprop pkg/port=10081 # svccfg -s pkg/server:MyIPSrepo setprop pkg/inst_root=/export/MyIPSrepo # svccfg -s pkg/server:MyIPSrepo addpg general framework # svccfg -s pkg/server:MyIPSrepo addpropvalue general/complete astring: MyIPSrepo # svccfg -s pkg/server:MyIPSrepo addpropvalue general/enabled boolean: true # svccfg -s pkg/server:MyIPSrepo setprop pkg/readonly=true # svccfg -s pkg/server:MyIPSrepo setprop pkg/proxy_base = astring: http://your_internal_websrvr/MyIPSrepo # svccfg -s pkg/server:MyIPSrepo setprop pkg/threads = 200 # svcadm refresh application/pkg/server:MyIPSrepo # svcadm enable application/pkg/server:MyIPSrepo Now that the IPS repo is created, we need to publish our package into it: # pkgsend publish -d ./proto -s /export/MyIPSrepo first-boot-script.p5m If you find yourself making changes to your script, remember to up-rev the version in the .p5m file (which is your IPS package manifest), and re-publish the IPS package. Next, you need to go to your AI install server (which might be the same machine) and modify the AI manifest to include a reference to your newly created package.  We do that by listing an additional publisher, which would look like this (replacing the IP address and port with your own, from the "svccfg" commands up above): <publisher name="firstboot"> <origin name="http://192.168.1.222:10081"/> </publisher>  Further down, in the  <software_data action="install">  section add: <name>pkg:/first-boot-script</name> Make sure to update your Automated Install service with the new AI manifest via installadm update-manifest command.  Don't forget to boot your client from the network to watch the entire process unfold and your script get tested.  Once the system makes the initial reboot, the first boot script will be executed and whatever logic you've specified in it should be executed, too, followed by a nice reboot. When the system comes up, your service should stay in a disabled state, as specified by the tailing lines of your SMF script - this is normal and should be left as is as it helps provide an auditing trail for you.   Because the reboot is quite a significant action for the system, you may want to add additional logic to the script that actually places and then checks for presence of certain lock files in order to avoid doing a reboot unnecessarily. You may also want to, alternatively, remove the SMF service entirely - if you're unsure of the potential for someone to try and accidentally enable that service -- eventhough its role in life is to only run once upon the system's first boot. That is how I spent a good chunk of my pre-Halloween time this week, hope yours was just as SPARCkly^H^H^H^H fun!

• Office 2010: It&rsquo;s not just DOC(X) and XLS(X)

  - by andrewbrust

  Office 2010 has released to manufacturing.  The bits have left the (product team’s) building.  Will you upgrade? This version of Office is officially numbered 14, a designation that correlates with the various releases, through the years, of Microsoft Word.  There were six major versions of Word for DOS, during whose release cycles came three 16-bit Windows versions.  Then, starting with Word 95 and counting through Word 2007, there have been six more versions – all for the 32-bit Windows platform.  Skip version 13 to ward off folksy bad luck (and, perhaps, the bugs that could come with it) and that brings us to version 14, which includes implementations for both 32- and 64-bit Windows platforms.  We’ve come a long way baby.  Or have we? As it does every three years or so, debate will now start to rage on over whether we need a “14th” version the PC platform’s standard word processor, or a “13th” version of the spreadsheet.  If you accept the premise of that question, then you may be on a slippery slope toward answering it in the negative.  Thing is, that premise is valid for certain customers and not others. The Microsoft Office product has morphed from one that offered core word processing, spreadsheet, presentation and email functionality to a suite of applications that provides unique, new value-added features, and even whole applications, in the context of those core services.  The core apps thus grow in mission: Excel is a BI tool.  Word is a collaborative editorial system for the production of publications.  PowerPoint is a media production platform for for live presentations and, increasingly, for delivering more effective presentations online.  Outlook is a time and task management system.  Access is a rich client front-end for data-driven self-service SharePoint applications.  OneNote helps you capture ideas, corral random thoughts in a semi-structured way, and then tie them back to other, more rigidly structured, Office documents. Google Docs and other cloud productivity platforms like Zoho don’t really do these things.  And there is a growing chorus of voices who say that they shouldn’t, because those ancillary capabilities are over-engineered, over-produced and “under-necessary.”  They might say Microsoft is layering on superfluous capabilities to avoid admitting that Office’s core capabilities, the ones people really need, have become commoditized. It’s hard to take sides in that argument, because different people, and the different companies that employ them, have different needs.  For my own needs, it all comes down to three basic questions: will the new version of Office save me time, will it make the mundane parts of my job easier, and will it augment my services to customers?  I need my time back.  I need to spend more of it with my family, and more of it focusing on my own core capabilities rather than the administrative tasks around them.  And I also need my customers to be able to get more value out of the services I provide. Help me triage my inbox, help me get proposals done more quickly and make them easier to read.  Let me get my presentations done faster, make them more effective and make it easier for me to reuse materials from other presentations.  And, since I’m in the BI and data business, help me and my customers manage data and analytics more easily, both on the desktop and online. Those are my criteria.  And, with those in mind, Office 2010 is looking like a worthwhile upgrade.  Perhaps it’s not earth-shattering, but it offers a combination of incremental improvements and a few new major capabilities that I think are quite compelling.  I provide a brief roundup of them here.  It’s admittedly arbitrary and not comprehensive, but I think it tells the Office 2010 story effectively. Across the Suite More than any other, this release of Office aims to give collaboration a real workout.  In certain apps, for the first time, documents can be opened simultaneously by multiple users, with colleagues’ changes appearing in near real-time.  Web-browser-based versions of Word, Excel, PowerPoint and OneNote will be available to extend collaboration to contributors who are off the corporate network. The ribbon user interface is now more pervasive (for example, it appears in OneNote and in Outlook’s main window).  It’s also customizable, allowing users to add, easily, buttons and options of their choosing, into new tabs, or into new groups within existing tabs. Microsoft has also taken the File menu (which was the “Office Button” menu in the 2007 release) and made it into a full-screen “Backstage” view where document-wide operations, like saving, printing and online publishing are performed. And because, more and more, heavily formatted content is cut and pasted between documents and applications, Office 2010 makes it easier to manage the retention or jettisoning of that formatting right as the paste operation is performed.  That’s much nicer than stripping it off, or adding it back, afterwards. And, speaking of pasting, a number of Office apps now make it especially easy to insert screenshots within their documents.  I know that’s useful to me, because I often document or critique applications and need to show them in action.  For the vast majority of users, I expect that this feature will be more useful for capturing snapshots of Web pages, but we’ll have to see whether this feature becomes popular.   Excel At first glance, Excel 2010 looks and acts nearly identically to the 2007 version.  But additional glances are necessary.  It’s important to understand that lots of people in the working world use Excel as more of a database, analytics and mathematical modeling tool than merely as a spreadsheet.  And it’s also important to understand that Excel wasn’t designed to handle such workloads past a certain scale.  That all changes with this release. The first reason things change is that Excel has been tuned for performance.  It’s been optimized for multi-threaded operation; previously lengthy processes have been shortened, especially for large data sets; more rows and columns are allowed and, for the first time, Excel (and the rest of Office) is available in a 64-bit version.  For Excel, this means users can take advantage of more than the 2GB of memory that the 32-bit version is limited to. On the analysis side, Excel 2010 adds Sparklines (tiny charts that fit into a single cell and can therefore be presented down an entire column or across a row) and Slicers (a more user-friendly filter mechanism for PivotTables and charts, which visually indicates what the filtered state of a given data member is).  But most important, Excel 2010 supports the new PowerPIvot add-in which brings true self-service BI to Office.  PowerPivot allows users to import data from almost anywhere, model it, and then analyze it.  Rather than forcing users to build “spreadmarts” or use corporate-built data warehouses, PowerPivot models function as true columnar, in-memory OLAP cubes that can accommodate millions of rows of data and deliver fast drill-down performance. And speaking of OLAP, Excel 2010 now supports an important Analysis Services OLAP feature called write-back.  Write-back is especially useful in financial forecasting scenarios for which Excel is the natural home.  Support for write-back is long overdue, but I’m still glad it’s there, because I had almost given up on it.   PowerPoint This version of PowerPoint marks its progression from a presentation tool to a video and photo editing and production tool.  Whether or not it’s successful in this pursuit, and if offering this is even a sensible goal, is another question. Regardless, the new capabilities are kind of interesting.  A greatly enhanced set of slide transitions with 3D effects; in-product photo and video editing; accommodation of embedded videos from services such as YouTube; and the ability to save a presentation as a video each lay testimony to PowerPoint’s transformation into a media tool and away from a pure presentation tool. These capabilities also recognize the importance of the Web as both a source for materials and a channel for disseminating PowerPoint output. Congruent with that is PowerPoint’s new ability to broadcast a slide presentation, using a quickly-generated public URL, without involving the hassle or expense of a Web meeting service like GoToMeeting or Microsoft’s own LiveMeeting.  Slides presented through this broadcast feature retain full color fidelity and transitions and animations are preserved as well.   Outlook Microsoft’s ubiquitous email/calendar/contact/task management tool gains long overdue speed improvements, especially against POP3 email accounts.  Outlook 2010 also supports multiple Exchange accounts, rather than just one; tighter integration with OneNote; and a new Social Connector providing integration with, and presence information from, online social network services like LinkedIn and Facebook (not to mention Windows Live).  A revamped conversation view now includes messages that are part of a given thread regardless of which folder they may be stored in. I don’t know yet how well the Social Connector will work or whether it will keep Outlook relevant to those who live on Facebook and LinkedIn.  But among the other features, there’s very little not to like.   OneNote To me, OneNote is the part of Office that just keeps getting better.  There is one major caveat to this, which I’ll cover in a moment, but let’s first catalog what new stuff OneNote 2010 brings.  The best part of OneNote, is the way each of its versions have managed hierarchy: Notebooks have sections, sections have pages, pages have sub pages, multiple notes can be contained in either, and each note supports infinite levels of indentation.  None of that is new to 2010, but the new version does make creation of pages and subpages easier and also makes simple work out of promoting and demoting pages from sub page to full page status.  And relationships between pages are quite easy to create now: much like a Wiki, simply typing a page’s name in double-square-brackets (“[[…]]”) creates a link to it. OneNote is also great at integrating content outside of its notebooks.  With a new Dock to Desktop feature, OneNote becomes aware of what window is displayed in the rest of the screen and, if it’s an Office document or a Web page, links the notes you’re typing, at the time, to it.  A single click from your notes later on will bring that same document or Web page back on-screen.  Embedding content from Web pages and elsewhere is also easier.  Using OneNote’s Windows Key+S combination to grab part of the screen now allows you to specify the destination of that bitmap instead of automatically creating a new note in the Unfiled Notes area.  Using the Send to OneNote buttons in Internet Explorer and Outlook result in the same choice. Collaboration gets better too.  Real-time multi-author editing is better accommodated and determining author lineage of particular changes is easily carried out. My one pet peeve with OneNote is the difficulty using it when I’m not one a Windows PC.  OneNote’s main competitor, Evernote, while I believe inferior in terms of features, has client versions for PC, Mac, Windows Mobile, Android, iPhone, iPad and Web browsers.  Since I have an Android phone and an iPad, I am practically forced to use it.  However, the OneNote Web app should help here, as should a forthcoming version of OneNote for Windows Phone 7.  In the mean time, it turns out that using OneNote’s Email Page ribbon button lets you move a OneNote page easily into EverNote (since every EverNote account gets a unique email address for adding notes) and that Evernote’s Email function combined with Outlook’s Send to OneNote button (in the Move group of the ribbon’s Home tab) can achieve the reverse.   Access To me, the big change in Access 2007 was its tight integration with SharePoint lists.  Access 2010 and SharePoint 2010 continue this integration with the introduction of SharePoint’s Access Services.  Much as Excel Services provides a SharePoint-hosted experience for viewing (and now editing) Excel spreadsheet, PivotTable and chart content, Access Services allows for SharePoint browser-hosted editing of Access data within the forms that are built in the Access client itself. To me this makes all kinds of sense.  Although it does beg the question of where to draw the line between Access, InfoPath, SharePoint list maintenance and SharePoint 2010’s new Business Connectivity Services.  Each of these tools provide overlapping data entry and data maintenance functionality. But if you do prefer Access, then you’ll like  things like templates and application parts that make it easier to get off the blank page.  These features help you quickly get tables, forms and reports built out.  To make things look nice, Access even gets its own version of Excel’s Conditional Formatting feature, letting you add data bars and data-driven text formatting.   Word As I said at the beginning of this post, upgrades to Office are about much more than enhancing the suite’s flagship word processing application. So are there any enhancements in Word worth mentioning?  I think so.  The most important one has to be the collaboration features.  Essentially, when a user opens a Word document that is in a SharePoint document library (or Windows Live SkyDrive folder), rather than the whole document being locked, Word has the ability to observe more granular locks on the individual paragraphs being edited.  Word also shows you who’s editing what and its Save function morphs into a sync feature that both saves your changes and loads those made by anyone editing the document concurrently. There’s also a new navigation pane that lets you manage sections in your document in much the same way as you manage slides in a PowerPoint deck.  Using the navigation pane, you can reorder sections, insert new ones, or promote and demote sections in the outline hierarchy.  Not earth shattering, but nice.   Other Apps and Summarized Findings What about InfoPath, Publisher, Visio and Project?  I haven’t looked at them yet.  And for this post, I think that’s fine.  While those apps (and, arguably, Access) cater to specific tasks, I think the apps we’ve looked at in this post service the general purpose needs of most users.  And the theme in those 2010 apps is clear: collaboration is key, the Web and productivity are indivisible, and making data and analytics into a self-service amenity is the way to go.  But perhaps most of all, features are still important, as long as they get you through your day faster, rather than adding complexity for its own sake.  I would argue that this is true for just about every product Microsoft makes: users want utility, not complexity.

• WCF WS-Security and WSE Nonce Authentication

  - by Rick Strahl

  WCF makes it fairly easy to access WS-* Web Services, except when you run into a service format that it doesn't support. Even then WCF provides a huge amount of flexibility to make the service clients work, however finding the proper interfaces to make that happen is not easy to discover and for the most part undocumented unless you're lucky enough to run into a blog, forum or StackOverflow post on the matter. This is definitely true for the Password Nonce as part of the WS-Security/WSE protocol, which is not natively supported in WCF. Specifically I had a need to create a WCF message on the client that includes a WS-Security header that looks like this from their spec document:<soapenv:Header> <wsse:Security soapenv:mustUnderstand="1" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> <wsse:UsernameToken wsu:Id="UsernameToken-8" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"> <wsse:Username>TeStUsErNaMe1</wsse:Username> <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText" >TeStPaSsWoRd1</wsse:Password> <wsse:Nonce EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary" >f8nUe3YupTU5ISdCy3X9Gg==</wsse:Nonce> <wsu:Created>2011-05-04T19:01:40.981Z</wsu:Created> </wsse:UsernameToken> </wsse:Security> </soapenv:Header> Specifically, the Nonce and Created keys are what WCF doesn't create or have a built in formatting for. Why is there a nonce? My first thought here was WTF? The username and password are there in clear text, what does the Nonce accomplish? The Nonce and created keys are are part of WSE Security specification and are meant to allow the server to detect and prevent replay attacks. The hashed nonce should be unique per request which the server can store and check for before running another request thus ensuring that a request is not replayed with exactly the same values. Basic ServiceUtl Import - not much Luck The first thing I did when I imported this service with a service reference was to simply import it as a Service Reference. The Add Service Reference import automatically detects that WS-Security is required and appropariately adds the WS-Security to the basicHttpBinding in the config file:<?xml version="1.0" encoding="utf-8" ?> <configuration> <system.serviceModel> <bindings> <basicHttpBinding> <binding name="RealTimeOnlineSoapBinding"> <security mode="Transport" /> </binding> <binding name="RealTimeOnlineSoapBinding1" /> </basicHttpBinding> </bindings> <client> <endpoint address="https://notarealurl.com:443/services/RealTimeOnline" binding="basicHttpBinding" bindingConfiguration="RealTimeOnlineSoapBinding" contract="RealTimeOnline.RealTimeOnline" name="RealTimeOnline" /> </client> </system.serviceModel> </configuration> If if I run this as is using code like this:var client = new RealTimeOnlineClient(); client.ClientCredentials.UserName.UserName = "TheUsername"; client.ClientCredentials.UserName.Password = "ThePassword"; … I get nothing in terms of WS-Security headers. The request is sent, but the the binding expects transport level security to be applied, rather than message level security. To fix this so that a WS-Security message header is sent the security mode can be changed to: <security mode="TransportWithMessageCredential" /> Now if I re-run I at least get a WS-Security header which looks like this:<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"> <s:Header> <o:Security s:mustUnderstand="1" xmlns:o="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> <u:Timestamp u:Id="_0"> <u:Created>2012-11-24T02:55:18.011Z</u:Created> <u:Expires>2012-11-24T03:00:18.011Z</u:Expires> </u:Timestamp> <o:UsernameToken u:Id="uuid-18c215d4-1106-40a5-8dd1-c81fdddf19d3-1"> <o:Username>TheUserName</o:Username> <o:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText" >ThePassword</o:Password> </o:UsernameToken> </o:Security> </s:Header> Closer! Now the WS-Security header is there along with a timestamp field (which might not be accepted by some WS-Security expecting services), but there's no Nonce or created timestamp as required by my original service. Using a CustomBinding instead My next try was to go with a CustomBinding instead of basicHttpBinding as it allows a bit more control over the protocol and transport configurations for the binding. Specifically I can explicitly specify the message protocol(s) used. Using configuration file settings here's what the config file looks like:<?xml version="1.0"?> <configuration> <system.serviceModel> <bindings> <customBinding> <binding name="CustomSoapBinding"> <security includeTimestamp="false" authenticationMode="UserNameOverTransport" defaultAlgorithmSuite="Basic256" requireDerivedKeys="false" messageSecurityVersion="WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10"> </security> <textMessageEncoding messageVersion="Soap11"></textMessageEncoding> <httpsTransport maxReceivedMessageSize="2000000000"/> </binding> </customBinding> </bindings> <client> <endpoint address="https://notrealurl.com:443/services/RealTimeOnline" binding="customBinding" bindingConfiguration="CustomSoapBinding" contract="RealTimeOnline.RealTimeOnline" name="RealTimeOnline" /> </client> </system.serviceModel> <startup> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/> </startup> </configuration> This ends up creating a cleaner header that's missing the timestamp field which can cause some services problems. The WS-Security header output generated with the above looks like this:<s:Header> <o:Security s:mustUnderstand="1" xmlns:o="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> <o:UsernameToken u:Id="uuid-291622ca-4c11-460f-9886-ac1c78813b24-1"> <o:Username>TheUsername</o:Username> <o:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText" >ThePassword</o:Password> </o:UsernameToken> </o:Security> </s:Header> This is closer as it includes only the username and password. The key here is the protocol for WS-Security:messageSecurityVersion="WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10" which explicitly specifies the protocol version. There are several variants of this specification but none of them seem to support the nonce unfortunately. This protocol does allow for optional omission of the Nonce and created timestamp provided (which effectively makes those keys optional). With some services I tried that requested a Nonce just using this protocol actually worked where the default basicHttpBinding failed to connect, so this is a possible solution for access to some services. Unfortunately for my target service that was not an option. The nonce has to be there. Creating Custom ClientCredentials As it turns out WCF doesn't have support for the Digest Nonce as part of WS-Security, and so as far as I can tell there's no way to do it just with configuration settings. I did a bunch of research on this trying to find workarounds for this, and I did find a couple of entries on StackOverflow as well as on the MSDN forums. However, none of these are particularily clear and I ended up using bits and pieces of several of them to arrive at a working solution in the end. http://stackoverflow.com/questions/896901/wcf-adding-nonce-to-usernametoken http://social.msdn.microsoft.com/Forums/en-US/wcf/thread/4df3354f-0627-42d9-b5fb-6e880b60f8ee The latter forum message is the more useful of the two (the last message on the thread in particular) and it has most of the information required to make this work. But it took some experimentation for me to get this right so I'll recount the process here maybe a bit more comprehensively. In order for this to work a number of classes have to be overridden: ClientCredentials ClientCredentialsSecurityTokenManager WSSecurityTokenizer The idea is that we need to create a custom ClientCredential class to hold the custom properties so they can be set from the UI or via configuration settings. The TokenManager and Tokenizer are mainly required to allow the custom credentials class to flow through the WCF pipeline and eventually provide custom serialization. Here are the three classes required and their full implementations:public class CustomCredentials : ClientCredentials { public CustomCredentials() { } protected CustomCredentials(CustomCredentials cc) : base(cc) { } public override System.IdentityModel.Selectors.SecurityTokenManager CreateSecurityTokenManager() { return new CustomSecurityTokenManager(this); } protected override ClientCredentials CloneCore() { return new CustomCredentials(this); } } public class CustomSecurityTokenManager : ClientCredentialsSecurityTokenManager { public CustomSecurityTokenManager(CustomCredentials cred) : base(cred) { } public override System.IdentityModel.Selectors.SecurityTokenSerializer CreateSecurityTokenSerializer(System.IdentityModel.Selectors.SecurityTokenVersion version) { return new CustomTokenSerializer(System.ServiceModel.Security.SecurityVersion.WSSecurity11); } } public class CustomTokenSerializer : WSSecurityTokenSerializer { public CustomTokenSerializer(SecurityVersion sv) : base(sv) { } protected override void WriteTokenCore(System.Xml.XmlWriter writer, System.IdentityModel.Tokens.SecurityToken token) { UserNameSecurityToken userToken = token as UserNameSecurityToken; string tokennamespace = "o"; DateTime created = DateTime.Now; string createdStr = created.ToString("yyyy-MM-ddThh:mm:ss.fffZ"); // unique Nonce value - encode with SHA-1 for 'randomness' // in theory the nonce could just be the GUID by itself string phrase = Guid.NewGuid().ToString(); var nonce = GetSHA1String(phrase); // in this case password is plain text // for digest mode password needs to be encoded as: // PasswordAsDigest = Base64(SHA-1(Nonce + Created + Password)) // and profile needs to change to //string password = GetSHA1String(nonce + createdStr + userToken.Password); string password = userToken.Password; writer.WriteRaw(string.Format( "<{0}:UsernameToken u:Id=\"" + token.Id + "\" xmlns:u=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd\">" + "<{0}:Username>" + userToken.UserName + "</{0}:Username>" + "<{0}:Password Type=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText\">" + password + "</{0}:Password>" + "<{0}:Nonce EncodingType=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary\">" + nonce + "</{0}:Nonce>" + "<u:Created>" + createdStr + "</u:Created></{0}:UsernameToken>", tokennamespace)); } protected string GetSHA1String(string phrase) { SHA1CryptoServiceProvider sha1Hasher = new SHA1CryptoServiceProvider(); byte[] hashedDataBytes = sha1Hasher.ComputeHash(Encoding.UTF8.GetBytes(phrase)); return Convert.ToBase64String(hashedDataBytes); } } Realistically only the CustomTokenSerializer has any significant code in. The code there deals with actually serializing the custom credentials using low level XML semantics by writing output into an XML writer. I can't take credit for this code - most of the code comes from the MSDN forum post mentioned earlier - I made a few adjustments to simplify the nonce generation and also added some notes to allow for PasswordDigest generation. Per spec the nonce is nothing more than a unique value that's supposed to be 'random'. I'm thinking that this value can be any string that's unique and a GUID on its own probably would have sufficed. Comments on other posts that GUIDs can be potentially guessed are highly exaggerated to say the least IMHO. To satisfy even that aspect though I added the SHA1 encryption and binary decoding to give a more random value that would be impossible to 'guess'. The original example from the forum post used another level of encoding and decoding to string in between - but that really didn't accomplish anything but extra overhead. The header output generated from this looks like this:<s:Header> <o:Security s:mustUnderstand="1" xmlns:o="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> <o:UsernameToken u:Id="uuid-f43d8b0d-0ebb-482e-998d-f544401a3c91-1" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"> <o:Username>TheUsername</o:Username> <o:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">ThePassword</o:Password> <o:Nonce EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary" >PjVE24TC6HtdAnsf3U9c5WMsECY=</o:Nonce> <u:Created>2012-11-23T07:10:04.670Z</u:Created> </o:UsernameToken> </o:Security> </s:Header> which is exactly as it should be. Password Digest? In my case the password is passed in plain text over an SSL connection, so there's no digest required so I was done with the code above. Since I don't have a service handy that requires a password digest,  I had no way of testing the code for the digest implementation, but here is how this is likely to work. If you need to pass a digest encoded password things are a little bit trickier. The password type namespace needs to change to: http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#Digest and then the password value needs to be encoded. The format for password digest encoding is this: Base64(SHA-1(Nonce + Created + Password)) and it can be handled in the code above with this code (that's commented in the snippet above): string password = GetSHA1String(nonce + createdStr + userToken.Password); The entire WriteTokenCore method for digest code looks like this:protected override void WriteTokenCore(System.Xml.XmlWriter writer, System.IdentityModel.Tokens.SecurityToken token) { UserNameSecurityToken userToken = token as UserNameSecurityToken; string tokennamespace = "o"; DateTime created = DateTime.Now; string createdStr = created.ToString("yyyy-MM-ddThh:mm:ss.fffZ"); // unique Nonce value - encode with SHA-1 for 'randomness' // in theory the nonce could just be the GUID by itself string phrase = Guid.NewGuid().ToString(); var nonce = GetSHA1String(phrase); string password = GetSHA1String(nonce + createdStr + userToken.Password); writer.WriteRaw(string.Format( "<{0}:UsernameToken u:Id=\"" + token.Id + "\" xmlns:u=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd\">" + "<{0}:Username>" + userToken.UserName + "</{0}:Username>" + "<{0}:Password Type=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#Digest\">" + password + "</{0}:Password>" + "<{0}:Nonce EncodingType=\"http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary\">" + nonce + "</{0}:Nonce>" + "<u:Created>" + createdStr + "</u:Created></{0}:UsernameToken>", tokennamespace)); } I had no service to connect to to try out Digest auth - if you end up needing it and get it to work please drop a comment… How to use the custom Credentials The easiest way to use the custom credentials is to create the client in code. Here's a factory method I use to create an instance of my service client:  public static RealTimeOnlineClient CreateRealTimeOnlineProxy(string url, string username, string password) { if (string.IsNullOrEmpty(url)) url = "https://notrealurl.com:443/cows/services/RealTimeOnline"; CustomBinding binding = new CustomBinding(); var security = TransportSecurityBindingElement.CreateUserNameOverTransportBindingElement(); security.IncludeTimestamp = false; security.DefaultAlgorithmSuite = SecurityAlgorithmSuite.Basic256; security.MessageSecurityVersion = MessageSecurityVersion.WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10; var encoding = new TextMessageEncodingBindingElement(); encoding.MessageVersion = MessageVersion.Soap11; var transport = new HttpsTransportBindingElement(); transport.MaxReceivedMessageSize = 20000000; // 20 megs binding.Elements.Add(security); binding.Elements.Add(encoding); binding.Elements.Add(transport); RealTimeOnlineClient client = new RealTimeOnlineClient(binding, new EndpointAddress(url)); // to use full client credential with Nonce uncomment this code: // it looks like this might not be required - the service seems to work without it client.ChannelFactory.Endpoint.Behaviors.Remove<System.ServiceModel.Description.ClientCredentials>(); client.ChannelFactory.Endpoint.Behaviors.Add(new CustomCredentials()); client.ClientCredentials.UserName.UserName = username; client.ClientCredentials.UserName.Password = password; return client; } This returns a service client that's ready to call other service methods. The key item in this code is the ChannelFactory endpoint behavior modification that that first removes the original ClientCredentials and then adds the new one. The ClientCredentials property on the client is read only and this is the way it has to be added.   Summary It's a bummer that WCF doesn't suport WSE Security authentication with nonce values out of the box. From reading the comments in posts/articles while I was trying to find a solution, I found that this feature was omitted by design as this protocol is considered unsecure. While I agree that plain text passwords are rarely a good idea even if they go over secured SSL connection as WSE Security does, there are unfortunately quite a few services (mosly Java services I suspect) that use this protocol. I've run into this twice now and trying to find a solution online I can see that this is not an isolated problem - many others seem to have struggled with this. It seems there are about a dozen questions about this on StackOverflow all with varying incomplete answers. Hopefully this post provides a little more coherent content in one place. Again I marvel at WCF and its breadth of support for protocol features it has in a single tool. And even when it can't handle something there are ways to get it working via extensibility. But at the same time I marvel at how freaking difficult it is to arrive at these solutions. I mean there's no way I could have ever figured this out on my own. It takes somebody working on the WCF team or at least being very, very intricately involved in the innards of WCF to figure out the interconnection of the various objects to do this from scratch. Luckily this is an older problem that has been discussed extensively online and I was able to cobble together a solution from the online content. I'm glad it worked out that way, but it feels dirty and incomplete in that there's a whole learning path that was omitted to get here… Man am I glad I'm not dealing with SOAP services much anymore. REST service security - even when using some sort of federation is a piece of cake by comparison :-) I'm sure once standards bodies gets involved we'll be right back in security standard hell…© Rick Strahl, West Wind Technologies, 2005-2012Posted in WCF  Web Services   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

  The Toorcon gang (senior staff): h1kari (founder), nfiltr8, and Geo Introduction to Toorcon 15 (2013) A Tale of One Software Bypass of MS Windows 8 Secure Boot Breaching SSL, One Byte at a Time Running at 99%: Surviving an Application DoS Security Response in the Age of Mass Customized Attacks x86 Rewriting: Defeating RoP and other Shinanighans Clowntown Express: interesting bugs and running a bug bounty program Active Fingerprinting of Encrypted VPNs Making Attacks Go Backwards Mask Your Checksums—The Gorry Details Adventures with weird machines thirty years after "Reflections on Trusting Trust" Introduction to Toorcon 15 (2013) Toorcon 15 is the 15th annual security conference held in San Diego. I've attended about a third of them and blogged about previous conferences I attended here starting in 2003. As always, I've only summarized the talks I attended and interested me enough to write about them. Be aware that I may have misrepresented the speaker's remarks and that they are not my remarks or opinion, or those of my employer, so don't quote me or them. Those seeking further details may contact the speakers directly or use The Google. For some talks, I have a URL for further information. A Tale of One Software Bypass of MS Windows 8 Secure Boot Andrew Furtak and Oleksandr Bazhaniuk Yuri Bulygin, Oleksandr ("Alex") Bazhaniuk, and (not present) Andrew Furtak Yuri and Alex talked about UEFI and Bootkits and bypassing MS Windows 8 Secure Boot, with vendor recommendations. They previously gave this talk at the BlackHat 2013 conference. MS Windows 8 Secure Boot Overview UEFI (Unified Extensible Firmware Interface) is interface between hardware and OS. UEFI is processor and architecture independent. Malware can replace bootloader (bootx64.efi, bootmgfw.efi). Once replaced can modify kernel. Trivial to replace bootloader. Today many legacy bootkits—UEFI replaces them most of them. MS Windows 8 Secure Boot verifies everything you load, either through signatures or hashes. UEFI firmware relies on secure update (with signed update). You would think Secure Boot would rely on ROM (such as used for phones0, but you can't do that for PCs—PCs use writable memory with signatures DXE core verifies the UEFI boat loader(s) OS Loader (winload.efi, winresume.efi) verifies the OS kernel A chain of trust is established with a root key (Platform Key, PK), which is a cert belonging to the platform vendor. Key Exchange Keys (KEKs) verify an "authorized" database (db), and "forbidden" database (dbx). X.509 certs with SHA-1/SHA-256 hashes. Keys are stored in non-volatile (NV) flash-based NVRAM. Boot Services (BS) allow adding/deleting keys (can't be accessed once OS starts—which uses Run-Time (RT)). Root cert uses RSA-2048 public keys and PKCS#7 format signatures. SecureBoot — enable disable image signature checks SetupMode — update keys, self-signed keys, and secure boot variables CustomMode — allows updating keys Secure Boot policy settings are: always execute, never execute, allow execute on security violation, defer execute on security violation, deny execute on security violation, query user on security violation Attacking MS Windows 8 Secure Boot Secure Boot does NOT protect from physical access. Can disable from console. Each BIOS vendor implements Secure Boot differently. There are several platform and BIOS vendors. It becomes a "zoo" of implementations—which can be taken advantage of. Secure Boot is secure only when all vendors implement it correctly. Allow only UEFI firmware signed updates protect UEFI firmware from direct modification in flash memory protect FW update components program SPI controller securely protect secure boot policy settings in nvram protect runtime api disable compatibility support module which allows unsigned legacy Can corrupt the Platform Key (PK) EFI root certificate variable in SPI flash. If PK is not found, FW enters setup mode wich secure boot turned off. Can also exploit TPM in a similar manner. One is not supposed to be able to directly modify the PK in SPI flash from the OS though. But they found a bug that they can exploit from User Mode (undisclosed) and demoed the exploit. It loaded and ran their own bootkit. The exploit requires a reboot. Multiple vendors are vulnerable. They will disclose this exploit to vendors in the future. Recommendations: allow only signed updates protect UEFI fw in ROM protect EFI variable store in ROM Breaching SSL, One Byte at a Time Yoel Gluck and Angelo Prado Angelo Prado and Yoel Gluck, Salesforce.com CRIME is software that performs a "compression oracle attack." This is possible because the SSL protocol doesn't hide length, and because SSL compresses the header. CRIME requests with every possible character and measures the ciphertext length. Look for the plaintext which compresses the most and looks for the cookie one byte-at-a-time. SSL Compression uses LZ77 to reduce redundancy. Huffman coding replaces common byte sequences with shorter codes. US CERT thinks the SSL compression problem is fixed, but it isn't. They convinced CERT that it wasn't fixed and they issued a CVE. BREACH, breachattrack.com BREACH exploits the SSL response body (Accept-Encoding response, Content-Encoding). It takes advantage of the fact that the response is not compressed. BREACH uses gzip and needs fairly "stable" pages that are static for ~30 seconds. It needs attacker-supplied content (say from a web form or added to a URL parameter). BREACH listens to a session's requests and responses, then inserts extra requests and responses. Eventually, BREACH guesses a session's secret key. Can use compression to guess contents one byte at-a-time. For example, "Supersecret SupersecreX" (a wrong guess) compresses 10 bytes, and "Supersecret Supersecret" (a correct guess) compresses 11 bytes, so it can find each character by guessing every character. To start the guess, BREACH needs at least three known initial characters in the response sequence. Compression length then "leaks" information. Some roadblocks include no winners (all guesses wrong) or too many winners (multiple possibilities that compress the same). The solutions include: lookahead (guess 2 or 3 characters at-a-time instead of 1 character). Expensive rollback to last known conflict check compression ratio can brute-force first 3 "bootstrap" characters, if needed (expensive) block ciphers hide exact plain text length. Solution is to align response in advance to block size Mitigations length: use variable padding secrets: dynamic CSRF tokens per request secret: change over time separate secret to input-less servlets Future work eiter understand DEFLATE/GZIP HTTPS extensions Running at 99%: Surviving an Application DoS Ryan Huber Ryan Huber, Risk I/O Ryan first discussed various ways to do a denial of service (DoS) attack against web services. One usual method is to find a slow web page and do several wgets. Or download large files. Apache is not well suited at handling a large number of connections, but one can put something in front of it Can use Apache alternatives, such as nginx How to identify malicious hosts short, sudden web requests user-agent is obvious (curl, python) same url requested repeatedly no web page referer (not normal) hidden links. hide a link and see if a bot gets it restricted access if not your geo IP (unless the website is global) missing common headers in request regular timing first seen IP at beginning of attack count requests per hosts (usually a very large number) Use of captcha can mitigate attacks, but you'll lose a lot of genuine users. Bouncer, goo.gl/c2vyEc and www.github.com/rawdigits/Bouncer Bouncer is software written by Ryan in netflow. Bouncer has a small, unobtrusive footprint and detects DoS attempts. It closes blacklisted sockets immediately (not nice about it, no proper close connection). Aggregator collects requests and controls your web proxies. Need NTP on the front end web servers for clean data for use by bouncer. Bouncer is also useful for a popularity storm ("Slashdotting") and scraper storms. Future features: gzip collection data, documentation, consumer library, multitask, logging destroyed connections. Takeaways: DoS mitigation is easier with a complete picture Bouncer designed to make it easier to detect and defend DoS—not a complete cure Security Response in the Age of Mass Customized Attacks Peleus Uhley and Karthik Raman Peleus Uhley and Karthik Raman, Adobe ASSET, blogs.adobe.com/asset/ Peleus and Karthik talked about response to mass-customized exploits. Attackers behave much like a business. "Mass customization" refers to concept discussed in the book Future Perfect by Stan Davis of Harvard Business School. Mass customization is differentiating a product for an individual customer, but at a mass production price. For example, the same individual with a debit card receives basically the same customized ATM experience around the world. Or designing your own PC from commodity parts. Exploit kits are another example of mass customization. The kits support multiple browsers and plugins, allows new modules. Exploit kits are cheap and customizable. Organized gangs use exploit kits. A group at Berkeley looked at 77,000 malicious websites (Grier et al., "Manufacturing Compromise: The Emergence of Exploit-as-a-Service", 2012). They found 10,000 distinct binaries among them, but derived from only a dozen or so exploit kits. Characteristics of Mass Malware: potent, resilient, relatively low cost Technical characteristics: multiple OS, multipe payloads, multiple scenarios, multiple languages, obfuscation Response time for 0-day exploits has gone down from ~40 days 5 years ago to about ~10 days now. So the drive with malware is towards mass customized exploits, to avoid detection There's plenty of evicence that exploit development has Project Manager bureaucracy. They infer from the malware edicts to: support all versions of reader support all versions of windows support all versions of flash support all browsers write large complex, difficult to main code (8750 lines of JavaScript for example Exploits have "loose coupling" of multipe versions of software (adobe), OS, and browser. This allows specific attacks against specific versions of multiple pieces of software. Also allows exploits of more obscure software/OS/browsers and obscure versions. Gave examples of exploits that exploited 2, 3, 6, or 14 separate bugs. However, these complete exploits are more likely to be buggy or fragile in themselves and easier to defeat. Future research includes normalizing malware and Javascript. Conclusion: The coming trend is that mass-malware with mass zero-day attacks will result in mass customization of attacks. x86 Rewriting: Defeating RoP and other Shinanighans Richard Wartell Richard Wartell The attack vector we are addressing here is: First some malware causes a buffer overflow. The malware has no program access, but input access and buffer overflow code onto stack Later the stack became non-executable. The workaround malware used was to write a bogus return address to the stack jumping to malware Later came ASLR (Address Space Layout Randomization) to randomize memory layout and make addresses non-deterministic. The workaround malware used was to jump t existing code segments in the program that can be used in bad ways "RoP" is Return-oriented Programming attacks. RoP attacks use your own code and write return address on stack to (existing) expoitable code found in program ("gadgets"). Pinkie Pie was paid $60K last year for a RoP attack. One solution is using anti-RoP compilers that compile source code with NO return instructions. ASLR does not randomize address space, just "gadgets". IPR/ILR ("Instruction Location Randomization") randomizes each instruction with a virtual machine. Richard's goal was to randomize a binary with no source code access. He created "STIR" (Self-Transofrming Instruction Relocation). STIR disassembles binary and operates on "basic blocks" of code. The STIR disassembler is conservative in what to disassemble. Each basic block is moved to a random location in memory. Next, STIR writes new code sections with copies of "basic blocks" of code in randomized locations. The old code is copied and rewritten with jumps to new code. the original code sections in the file is marked non-executible. STIR has better entropy than ASLR in location of code. Makes brute force attacks much harder. STIR runs on MS Windows (PEM) and Linux (ELF). It eliminated 99.96% or more "gadgets" (i.e., moved the address). Overhead usually 5-10% on MS Windows, about 1.5-4% on Linux (but some code actually runs faster!). The unique thing about STIR is it requires no source access and the modified binary fully works! Current work is to rewrite code to enforce security policies. For example, don't create a *.{exe,msi,bat} file. Or don't connect to the network after reading from the disk. Clowntown Express: interesting bugs and running a bug bounty program Collin Greene Collin Greene, Facebook Collin talked about Facebook's bug bounty program. Background at FB: FB has good security frameworks, such as security teams, external audits, and cc'ing on diffs. But there's lots of "deep, dark, forgotten" parts of legacy FB code. Collin gave several examples of bountied bugs. Some bounty submissions were on software purchased from a third-party (but bounty claimers don't know and don't care). We use security questions, as does everyone else, but they are basically insecure (often easily discoverable). Collin didn't expect many bugs from the bounty program, but they ended getting 20+ good bugs in first 24 hours and good submissions continue to come in. Bug bounties bring people in with different perspectives, and are paid only for success. Bug bounty is a better use of a fixed amount of time and money versus just code review or static code analysis. The Bounty program started July 2011 and paid out $1.5 million to date. 14% of the submissions have been high priority problems that needed to be fixed immediately. The best bugs come from a small % of submitters (as with everything else)—the top paid submitters are paid 6 figures a year. Spammers like to backstab competitors. The youngest sumitter was 13. Some submitters have been hired. Bug bounties also allows to see bugs that were missed by tools or reviews, allowing improvement in the process. Bug bounties might not work for traditional software companies where the product has release cycle or is not on Internet. Active Fingerprinting of Encrypted VPNs Anna Shubina Anna Shubina, Dartmouth Institute for Security, Technology, and Society (I missed the start of her talk because another track went overtime. But I have the DVD of the talk, so I'll expand later) IPsec leaves fingerprints. Using netcat, one can easily visually distinguish various crypto chaining modes just from packet timing on a chart (example, DES-CBC versus AES-CBC) One can tell a lot about VPNs just from ping roundtrips (such as what router is used) Delayed packets are not informative about a network, especially if far away from the network More needed to explore about how TCP works in real life with respect to timing Making Attacks Go Backwards Fuzzynop FuzzyNop, Mandiant This talk is not about threat attribution (finding who), product solutions, politics, or sales pitches. But who are making these malware threats? It's not a single person or group—they have diverse skill levels. There's a lot of fat-fingered fumblers out there. Always look for low-hanging fruit first: "hiding" malware in the temp, recycle, or root directories creation of unnamed scheduled tasks obvious names of files and syscalls ("ClearEventLog") uncleared event logs. Clearing event log in itself, and time of clearing, is a red flag and good first clue to look for on a suspect system Reverse engineering is hard. Disassembler use takes practice and skill. A popular tool is IDA Pro, but it takes multiple interactive iterations to get a clean disassembly. Key loggers are used a lot in targeted attacks. They are typically custom code or built in a backdoor. A big tip-off is that non-printable characters need to be printed out (such as "[Ctrl]" "[RightShift]") or time stamp printf strings. Look for these in files. Presence is not proof they are used. Absence is not proof they are not used. Java exploits. Can parse jar file with idxparser.py and decomile Java file. Java typially used to target tech companies. Backdoors are the main persistence mechanism (provided externally) for malware. Also malware typically needs command and control. Application of Artificial Intelligence in Ad-Hoc Static Code Analysis John Ashaman John Ashaman, Security Innovation Initially John tried to analyze open source files with open source static analysis tools, but these showed thousands of false positives. Also tried using grep, but tis fails to find anything even mildly complex. So next John decided to write his own tool. His approach was to first generate a call graph then analyze the graph. However, the problem is that making a call graph is really hard. For example, one problem is "evil" coding techniques, such as passing function pointer. First the tool generated an Abstract Syntax Tree (AST) with the nodes created from method declarations and edges created from method use. Then the tool generated a control flow graph with the goal to find a path through the AST (a maze) from source to sink. The algorithm is to look at adjacent nodes to see if any are "scary" (a vulnerability), using heuristics for search order. The tool, called "Scat" (Static Code Analysis Tool), currently looks for C# vulnerabilities and some simple PHP. Later, he plans to add more PHP, then JSP and Java. For more information see his posts in Security Innovation blog and NRefactory on GitHub. Mask Your Checksums—The Gorry Details Eric (XlogicX) Davisson Eric (XlogicX) Davisson Sometimes in emailing or posting TCP/IP packets to analyze problems, you may want to mask the IP address. But to do this correctly, you need to mask the checksum too, or you'll leak information about the IP. Problem reports found in stackoverflow.com, sans.org, and pastebin.org are usually not masked, but a few companies do care. If only the IP is masked, the IP may be guessed from checksum (that is, it leaks data). Other parts of packet may leak more data about the IP. TCP and IP checksums both refer to the same data, so can get more bits of information out of using both checksums than just using one checksum. Also, one can usually determine the OS from the TTL field and ports in a packet header. If we get hundreds of possible results (16x each masked nibble that is unknown), one can do other things to narrow the results, such as look at packet contents for domain or geo information. With hundreds of results, can import as CSV format into a spreadsheet. Can corelate with geo data and see where each possibility is located. Eric then demoed a real email report with a masked IP packet attached. Was able to find the exact IP address, given the geo and university of the sender. Point is if you're going to mask a packet, do it right. Eric wouldn't usually bother, but do it correctly if at all, to not create a false impression of security. Adventures with weird machines thirty years after "Reflections on Trusting Trust" Sergey Bratus Sergey Bratus, Dartmouth College (and Julian Bangert and Rebecca Shapiro, not present) "Reflections on Trusting Trust" refers to Ken Thompson's classic 1984 paper. "You can't trust code that you did not totally create yourself." There's invisible links in the chain-of-trust, such as "well-installed microcode bugs" or in the compiler, and other planted bugs. Thompson showed how a compiler can introduce and propagate bugs in unmodified source. But suppose if there's no bugs and you trust the author, can you trust the code? Hell No! There's too many factors—it's Babylonian in nature. Why not? Well, Input is not well-defined/recognized (code's assumptions about "checked" input will be violated (bug/vunerabiliy). For example, HTML is recursive, but Regex checking is not recursive. Input well-formed but so complex there's no telling what it does For example, ELF file parsing is complex and has multiple ways of parsing. Input is seen differently by different pieces of program or toolchain Any Input is a program input executes on input handlers (drives state changes & transitions) only a well-defined execution model can be trusted (regex/DFA, PDA, CFG) Input handler either is a "recognizer" for the inputs as a well-defined language (see langsec.org) or it's a "virtual machine" for inputs to drive into pwn-age ELF ABI (UNIX/Linux executible file format) case study. Problems can arise from these steps (without planting bugs): compiler linker loader ld.so/rtld relocator DWARF (debugger info) exceptions The problem is you can't really automatically analyze code (it's the "halting problem" and undecidable). Only solution is to freeze code and sign it. But you can't freeze everything! Can't freeze ASLR or loading—must have tables and metadata. Any sufficiently complex input data is the same as VM byte code Example, ELF relocation entries + dynamic symbols == a Turing Complete Machine (TM). @bxsays created a Turing machine in Linux from relocation data (not code) in an ELF file. For more information, see Rebecca "bx" Shapiro's presentation from last year's Toorcon, "Programming Weird Machines with ELF Metadata" @bxsays did same thing with Mach-O bytecode Or a DWARF exception handling data .eh_frame + glibc == Turning Machine X86 MMU (IDT, GDT, TSS): used address translation to create a Turning Machine. Page handler reads and writes (on page fault) memory. Uses a page table, which can be used as Turning Machine byte code. Example on Github using this TM that will fly a glider across the screen Next Sergey talked about "Parser Differentials". That having one input format, but two parsers, will create confusion and opportunity for exploitation. For example, CSRs are parsed during creation by cert requestor and again by another parser at the CA. Another example is ELF—several parsers in OS tool chain, which are all different. Can have two different Program Headers (PHDRs) because ld.so parses multiple PHDRs. The second PHDR can completely transform the executable. This is described in paper in the first issue of International Journal of PoC. Conclusions trusting computers not only about bugs! Bugs are part of a problem, but no by far all of it complex data formats means bugs no "chain of trust" in Babylon! (that is, with parser differentials) we need to squeeze complexity out of data until data stops being "code equivalent" Further information See and langsec.org.

• Tips on Migrating from AquaLogic .NET Accelerator to WebCenter WSRP Producer for .NET

  - by user647124

  This year I embarked on a journey to migrate a group of ASP.NET web applications developed to integrate with WebLogic Portal 9.2 via the AquaLogic® Interaction .NET Application Accelerator 1.0 to instead use the Oracle WebCenter WSRP Producer for .NET and integrated with WebLogic Portal 10.3.4. It has been a very winding path and this blog entry is intended to share both the lessons learned and relevant approaches that led to those learnings. Like most journeys of discovery, it was not a direct path, and there are notes to let you know when it is practical to skip a section if you are in a hurry to get from here to there. For the Curious From the perspective of necessity, this section would be better at the end. If it were there, though, it would probably be read by far fewer people, including those that are actually interested in these types of sections. Those in a hurry may skip past and be none the worst for it in dealing with the hands-on bits of performing a migration from .NET Accelerator to WSRP Producer. For others who want to talk about why they did what they did after they did it, or just want to know for themselves, enjoy. A Brief (and edited) History of the WSRP for .NET Technologies (as Relevant to the this Post) Note: This section is for those who are curious about why the migration path is not as simple as many other Oracle technologies. You can skip this section in its entirety and still be just as competent in performing a migration as if you had read it. The currently deployed architecture that was to be migrated and upgraded achieved initial integration between .NET and J2EE over the WSRP protocol through the use of The AquaLogic Interaction .NET Application Accelerator. The .NET Accelerator allowed the applications that were written in ASP.NET and deployed on a Microsoft Internet Information Server (IIS) to interact with a WebLogic Portal application deployed on a WebLogic (J2EE application) Server (both version 9.2, the state of the art at the time of its creation). At the time this architectural decision for the application was made, both the AquaLogic and WebLogic brands were owned by BEA Systems. The AquaLogic brand included products acquired by BEA through the acquisition of Plumtree, whose flagship product was a portal platform available in both J2EE and .NET versions. As part of this dual technology support an adaptor was created to facilitate the use of WSRP as a communication protocol where customers wished to integrate components from both versions of the Plumtree portal. The adapter evolved over several product generations to include a broad array of both standard and proprietary WSRP integration capabilities. Later, BEA Systems was acquired by Oracle. Over the course of several years Oracle has acquired a large number of portal applications and has taken the strategic direction to migrate users of these myriad (and formerly competitive) products to the Oracle WebCenter technology stack. As part of Oracle’s strategic technology roadmap, older portal products are being schedule for end of life, including the portal products that were part of the BEA acquisition. The .NET Accelerator has been modified over a very long period of time with features driven by users of that product and developed under three different vendors (each a direct competitor in the same solution space prior to merger). The Oracle WebCenter WSRP Producer for .NET was introduced much more recently with the key objective to specifically address the needs of the WebCenter customers developing solutions accessible through both J2EE and .NET platforms utilizing the WSRP specifications. The Oracle Product Development Team also provides these insights on the drivers for developing the WSRP Producer: ***************************************** Support for ASP.NET AJAX. Controls using the ASP.NET AJAX script manager do not function properly in the Application Accelerator for .NET. Support 2 way SSL in WLP. This was not possible with the proxy/bridge set up in the existing Application Accelerator for .NET. Allow developers to code portlets (Web Parts) using the .NET framework rather than a proprietary framework. Developers had to use the Application Accelerator for .NET plug-ins to Visual Studio to manage preferences and profile data. This is now replaced with the .NET Framework Personalization (for preferences) and Profile providers. The WSRP Producer for .NET was created as a new way of developing .NET portlets. It was never designed to be an upgrade path for the Application Accelerator for .NET. .NET developers would create new .NET portlets with the WSRP Producer for .NET and leave any existing .NET portlets running in the Application Accelerator for .NET. ***************************************** The advantage to creating a new solution for WSRP is a product that is far easier for Oracle to maintain and support which in turn improves quality, reliability and maintainability for their customers. No changes to J2EE applications consuming the WSRP portlets previously rendered by the.NET Accelerator is required to migrate from the Aqualogic WSRP solution. For some customers using the .NET Accelerator the challenge is adapting their current .NET applications to work with the WSRP Producer (or any other WSRP adapter as they are proprietary by nature). Part of this adaptation is the need to deploy the .NET applications as a child to the WSRP producer web application as root. Differences between .NET Accelerator and WSRP Producer Note: This section is for those who are curious about why the migration is not as pluggable as something such as changing security providers in WebLogic Server. You can skip this section in its entirety and still be just as competent in performing a migration as if you had read it. The basic terminology used to describe the participating applications in a WSRP environment are the same when applied to either the .NET Accelerator or the WSRP Producer: Producer and Consumer. In both cases the .NET application serves as what is referred to as a WSRP environment as the Producer. The difference lies in how the two adapters create the WSRP translation of the .NET application. The .NET Accelerator, as the name implies, is meant to serve as a quick way of adding WSRP capability to a .NET application. As such, at a high level, the .NET Accelerator behaves as a proxy for requests between the .NET application and the WSRP Consumer. A WSRP request is sent from the consumer to the .NET Accelerator, the.NET Accelerator transforms this request into an ASP.NET request, receives the response, then transforms the response into a WSRP response. The .NET Accelerator is deployed as a stand-alone application on IIS. The WSRP Producer is deployed as a parent application on IIS and all ASP.NET modules that will be made available over WSRP are deployed as children of the WSRP Producer application. In this manner, the WSRP Producer acts more as a Request Filter than a proxy in the WSRP transactions between Producer and Consumer. Highly Recommended Enabling Logging Note: You can skip this section now, but you will most likely want to come back to it later, so why not just read it now? Logging is very helpful in tracking down the causes of any anomalies during testing of migrated portlets. To enable the WSRP Producer logging, update the Application_Start method in the Global.asax.cs for your .NET application by adding log4net.Config.XmlConfigurator.Configure(); IIS logs will usually (in a standard configuration) be in a sub folder under C:\WINDOWS\system32\LogFiles\W3SVC. WSRP Producer logs will be found at C:\Oracle\Middleware\WSRPProducerForDotNet\wsrpdefault\Logs\WSRPProducer.log InputTrace.webinfo and OutputTrace.webinfo are located under C:\Oracle\Middleware\WSRPProducerForDotNet\wsrpdefault and can be useful in debugging issues related to markup transformations. Things You Must Do Merge Web.Config Note: If you have been skipping all the sections that you can, now is the time to stop and pay attention J Because the existing .NET application will become a sub-application to the WSRP Producer, you will want to merge required settings from the existing Web.Config to the one in the WSRP Producer. Use the WSRP Producer Master Page The Master Page installed for the WSRP Producer provides common, hiddenform fields and JavaScripts to facilitate portlet instance management and display configuration when the child page is being rendered over WSRP. You add the Master Page by including it in the <@ Page declaration with MasterPageFile="~/portlets/Resources/MasterPages/WSRP.Master" . You then replace: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" > <HTML> <HEAD> With <asp:Content ID="ContentHead1" ContentPlaceHolderID="wsrphead" Runat="Server"> And </HEAD> <body> <form id="theForm" method="post" runat="server"> With </asp:Content> <asp:Content ID="ContentBody1" ContentPlaceHolderID="Main" Runat="Server"> And finally </form> </body> </HTML> With </asp:Content> In the event you already use Master Pages, adapt your existing Master Pages to be sub masters. See Nested ASP.NET Master Pages for a detailed reference of how to do this. It Happened to Me, It Might Happen to You…Or Not Watch for Use of Session or Request in OnInit In the event the .NET application being modified has pages developed to assume the user has been authenticated in an earlier page request there may be direct or indirect references in the OnInit method to request or session objects that may not have been created yet. This will vary from application to application, so the recommended approach is to test first. If there is an issue with a page running as a WSRP portlet then check for potential references in the OnInit method (including references by methods called within OnInit) to session or request objects. If there are, the simplest solution is to create a new method and then call that method once the necessary object(s) is fully available. I find doing this at the start of the Page_Load method to be the simplest solution. Case Sensitivity .NET languages are not case sensitive, but Java is. This means it is possible to have many variations of SRC= and src= or .JPG and .jpg. The preferred solution is to make these mark up instances all lower case in your .NET application. This will allow the default Rewriter rules in wsrp-producer.xml to work as is. If this is not practical, then make duplicates of any rules where an issue is occurring due to upper or mixed case usage in the .NET application markup and match the case in use with the duplicate rule. For example: <RewriterRule> <LookFor>(href=\"([^\"]+)</LookFor> <ChangeToAbsolute>true</ChangeToAbsolute> <ApplyTo>.axd,.css</ApplyTo> <MakeResource>true</MakeResource> </RewriterRule> May need to be duplicated as: <RewriterRule> <LookFor>(HREF=\"([^\"]+)</LookFor> <ChangeToAbsolute>true</ChangeToAbsolute> <ApplyTo>.axd,.css</ApplyTo> <MakeResource>true</MakeResource> </RewriterRule> While it is possible to write a regular expression that will handle mixed case usage, it would be long and strenous to test and maintain, so the recommendation is to use duplicate rules. Is it Still Relative? Some .NET applications base relative paths with a fixed root location. With the introduction of the WSRP Producer, the root has moved up one level. References to ~/ will need to be updated to ~/portlets and many ../ paths will need another ../ in front. I Can See You But I Can’t Find You This issue was first discovered while debugging modules with code that referenced the form on a page from the code-behind by name and/or id. The initial error presented itself as run-time error that was difficult to interpret over WSRP but seemed clear when run as straight ASP.NET as it indicated that the object with the form name did not exist. Since the form name was no longer valid after implementing the WSRP Master Page, the likely fix seemed to simply update the references in the code. However, as the WSRP Master Page is external to the code, a compile time error resulted: Error      155         The name 'form1' does not exist in the current context                C:\Oracle\Middleware\WSRPProducerForDotNet\wsrpdefault\portlets\legacywebsite\module\Screens \Reporting.aspx.cs                51           52           legacywebsite.module Much hair-pulling research later it was discovered that it was the use of the FindControl method causing the issue. FindControl doesn’t work quite as expected once a Master Page has been introduced as the controls become embedded in controls, require a recursion to find them that is not part of the FindControl method. In code where the page form is referenced by name, there are two steps to the solution. First, the form needs to be referenced in code generically with Page.Form. For example, this: ToggleControl ctrl = new ToggleControl(frmManualEntry, FunctionLibrary.ParseArrayLst(userObj.Roles)); Becomes this: ToggleControl ctrl = new ToggleControl(Page.Form, FunctionLibrary.ParseArrayLst(userObj.Roles)); Generally the form id is referenced in most ASP.NET applications as a path to a control on the form. To reach the control once a MasterPage has been added requires an additional method to recurse through the controls collections within the form and find the control ID. The following method (found at Rick Strahl's Web Log) corrects this very nicely: public static Control FindControlRecursive(Control Root, string Id) { if (Root.ID == Id) return Root; foreach (Control Ctl in Root.Controls) { Control FoundCtl = FindControlRecursive(Ctl, Id); if (FoundCtl != null) return FoundCtl; } return null; } Where the form name is not referenced, simply using the FindControlRecursive method in place of FindControl will be all that is necessary. Following the second part of the example referenced earlier, the method called with Page.Form changes its value extraction code block from this: Label lblErrMsg = (Label)frmRef.FindControl("lblBRMsg" To this: Label lblErrMsg = (Label) FunctionLibrary.FindControlRecursive(frmRef, "lblBRMsg" The Master That Won’t Step Aside In most migrations it is preferable to make as few changes as possible. In one case I ran across an existing Master Page that would not function as a sub-Master Page. While it would probably have been educational to trace down why, the expedient process of updating it to take the place of the WSRP Master Page is the route I took. The changes are highlighted below: … <asp:ContentPlaceHolder ID="wsrphead" runat="server"></asp:ContentPlaceHolder> </head> <body leftMargin="0" topMargin="0"> <form id="TheForm" runat="server"> <input type="hidden" name="key" id="key" value="" /> <input type="hidden" name="formactionurl" id="formactionurl" value="" /> <input type="hidden" name="handle" id="handle" value="" /> <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true" > </asp:ScriptManager> This approach did not work for all existing Master Pages, but fortunately all of the other existing Master Pages I have run across worked fine as a sub-Master to the WSRP Master Page. Moving On In Enterprise Portals, even after you get everything working, the work is not finished. Next you need to get it where everyone will work with it. Migration Planning Providing that the server where IIS is running is adequately sized, it is possible to run both the .NET Accelerator and the WSRP Producer on the same server during the upgrade process. The upgrade can be performed incrementally, i.e., one portlet at a time, if server administration processes support it. Those processes would include the ability to manage a second producer in the consuming portal and to change over individual portlet instances from one provider to the other. If processes or requirements demand that all portlets be cut over at the same time, it needs to be determined if this cut over should include a new producer, updating all of the portlets in the consumer, or if the WSRP Producer portlet configuration must maintain the naming conventions used by the .NET Accelerator and simply change the WSRP end point configured in the consumer. In some enterprises it may even be necessary to maintain the same WSDL end point, at which point the IIS configuration will be where the updates occur. The downside to such a requirement is that it makes rolling back very difficult, should the need arise. Location, Location, Location Not everyone wants the web application to have the descriptively obvious wsrpdefault location, or needs to create a second WSRP site on the same server. The instructions below are from the product team and, while targeted towards making a second site, will work for creating a site with a different name and then remove the old site. You can also change just the name in IIS. Manually Creating a WSRP Producer Site Instructions (NOTE: all executables used are the same ones used by the installer and “wsrpdev” will be the name of the new instance): 1. Copy C:\Oracle\Middleware\WSRPProducerForDotNet\wsrpdefault to C:\Oracle\Middleware\WSRPProducerForDotNet\wsrpdev. 2. Bring up a command window as an administrator 3. Run C:\Oracle\Middleware\WSRPProducerForDotNet\uninstall_resources\IISAppAccelSiteCreator.exe install WSRPProducers wsrpdev "C:\Oracle\Middleware\WSRPProducerForDotNet\wsrpdev" 8678 2.0.50727 4. Run C:\Oracle\Middleware\WSRPProducerForDotNet\uninstall_resources\PermManage.exe add FileSystem C:\Oracle\Middleware\WSRPProducerForDotNet\wsrpdev "NETWORK SERVICE" 3 1 5. Run C:\Oracle\Middleware\WSRPProducerForDotNet\uninstall_resources\PermManage.exe add FileSystem C:\Oracle\Middleware\WSRPProducerForDotNet\wsrpdev EVERYONE 1 1 6. Open up C:\Oracle\Middleware\WSRPProducerForDotNet\wsdl\1.0\WSRPService.wsdl and replace wsrpdefault with wsrpdev 7. Open up C:\Oracle\Middleware\WSRPProducerForDotNet\wsdl\2.0\WSRPService.wsdl and replace wsrpdefault with wsrpdev Tests: 1. Bring up a browser on the host itself and go to http://localhost:8678/wsrpdev/wsdl/1.0/WSRPService.wsdl and make sure that the URLs in the XML returned include the wsrpdev changes you made in step 6. 2. Bring up a browser on the host itself and see if the default sample comes up: http://localhost:8678/wsrpdev/portlets/ASPNET_AJAX_sample/default.aspx 3. Register the producer in WLP and test the portlet. Changing the Port used by WSRP Producer The pre-configured port for the WSRP Producer is 8678. You can change this port by updating both the IIS configuration and C:\Oracle\Middleware\WSRPProducerForDotNet\[WSRP_APP_NAME]\wsdl\1.0\WSRPService.wsdl. Do You Need to Migrate? Oracle Premier Support ended in November of 2010 for AquaLogic Interaction .NET Application Accelerator 1.x and Extended Support ends in November 2012 (see http://www.oracle.com/us/support/lifetime-support/lifetime-support-software-342730.html for other related dates). This means that integration with products released after November of 2010 is not supported. If having such support is the policy within your enterprise, you do indeed need to migrate. If changes in your enterprise cause your current solution with the .NET Accelerator to no longer function properly, you may need to migrate. Migration is a choice, and if the goals of your enterprise are to take full advantage of newer technologies then migration is certainly one activity you should be planning for.

• PTLQueue : a scalable bounded-capacity MPMC queue

  - by Dave

  Title: Fast concurrent MPMC queue -- I've used the following concurrent queue algorithm enough that it warrants a blog entry. I'll sketch out the design of a fast and scalable multiple-producer multiple-consumer (MPSC) concurrent queue called PTLQueue. The queue has bounded capacity and is implemented via a circular array. Bounded capacity can be a useful property if there's a mismatch between producer rates and consumer rates where an unbounded queue might otherwise result in excessive memory consumption by virtue of the container nodes that -- in some queue implementations -- are used to hold values. A bounded-capacity queue can provide flow control between components. Beware, however, that bounded collections can also result in resource deadlock if abused. The put() and take() operators are partial and wait for the collection to become non-full or non-empty, respectively. Put() and take() do not allocate memory, and are not vulnerable to the ABA pathologies. The PTLQueue algorithm can be implemented equally well in C/C++ and Java. Partial operators are often more convenient than total methods. In many use cases if the preconditions aren't met, there's nothing else useful the thread can do, so it may as well wait via a partial method. An exception is in the case of work-stealing queues where a thief might scan a set of queues from which it could potentially steal. Total methods return ASAP with a success-failure indication. (It's tempting to describe a queue or API as blocking or non-blocking instead of partial or total, but non-blocking is already an overloaded concurrency term. Perhaps waiting/non-waiting or patient/impatient might be better terms). It's also trivial to construct partial operators by busy-waiting via total operators, but such constructs may be less efficient than an operator explicitly and intentionally designed to wait. A PTLQueue instance contains an array of slots, where each slot has volatile Turn and MailBox fields. The array has power-of-two length allowing mod/div operations to be replaced by masking. We assume sensible padding and alignment to reduce the impact of false sharing. (On x86 I recommend 128-byte alignment and padding because of the adjacent-sector prefetch facility). Each queue also has PutCursor and TakeCursor cursor variables, each of which should be sequestered as the sole occupant of a cache line or sector. You can opt to use 64-bit integers if concerned about wrap-around aliasing in the cursor variables. Put(null) is considered illegal, but the caller or implementation can easily check for and convert null to a distinguished non-null proxy value if null happens to be a value you'd like to pass. Take() will accordingly convert the proxy value back to null. An advantage of PTLQueue is that you can use atomic fetch-and-increment for the partial methods. We initialize each slot at index I with (Turn=I, MailBox=null). Both cursors are initially 0. All shared variables are considered "volatile" and atomics such as CAS and AtomicFetchAndIncrement are presumed to have bidirectional fence semantics. Finally T is the templated type. I've sketched out a total tryTake() method below that allows the caller to poll the queue. tryPut() has an analogous construction.

The latter is essentially a circular ring-buffer where the elements themselves are queues or concurrent collections. You can think of the PTLQueue as a partitioned ticket lock "PTL" augmented to pass values from lock to unlock via the slots. Alternatively, you could conceptualize of PTLQueue as a degenerate MultiLane bag where each slot or "lane" consists of a simple single-word MailBox instead of a general queue. Each lane in PTLQueue also has a private Turn field which acts like the Turn (Grant) variables found in PTL. Turn enforces strict FIFO ordering and restricts concurrency on the slot mailbox field to at most one simultaneous put() and take() operation. PTL uses a single "ticket" variable and per-slot Turn (grant) fields while MultiLane has distinct PutCursor and TakeCursor cursors and abstract per-slot sub-queues. Both PTL and MultiLane advance their cursor and ticket variables with atomic fetch-and-increment. PTLQueue borrows from both PTL and MultiLane and has distinct put and take cursors and per-slot Turn fields. Instead of a per-slot queues, PTLQueue uses a simple single-word MailBox field. PutCursor and TakeCursor act like a pair of ticket locks, conferring "put" and "take" access to a given slot. PutCursor, for instance, assigns an incoming put() request to a slot and serves as a PTL "Ticket" to acquire "put" permission to that slot's MailBox field. To better explain the operation of PTLQueue we deconstruct the operation of put() and take() as follows. Put() first increments PutCursor obtaining a new unique ticket. That ticket value also identifies a slot. Put() next waits for that slot's Turn field to match that ticket value. This is tantamount to using a PTL to acquire "put" permission on the slot's MailBox field. Finally, having obtained exclusive "put" permission on the slot, put() stores the message value into the slot's MailBox. Take() similarly advances TakeCursor, identifying a slot, and then acquires and secures "take" permission on a slot by waiting for Turn. Take() then waits for the slot's MailBox to become non-empty, extracts the message, and clears MailBox. Finally, take() advances the slot's Turn field, which releases both "put" and "take" access to the slot's MailBox. Note the asymmetry : put() acquires "put" access to the slot, but take() releases that lock. At any given time, for a given slot in a PTLQueue, at most one thread has "put" access and at most one thread has "take" access. This restricts concurrency from general MPMC to 1-vs-1. We have 2 ticket locks -- one for put() and one for take() -- each with its own "ticket" variable in the form of the corresponding cursor, but they share a single "Grant" egress variable in the form of the slot's Turn variable. Advancing the PutCursor, for instance, serves two purposes. First, we obtain a unique ticket which identifies a slot. Second, incrementing the cursor is the doorway protocol step to acquire the per-slot mutual exclusion "put" lock. The cursors and operations to increment those cursors serve double-duty : slot-selection and ticket assignment for locking the slot's MailBox field. At any given time a slot MailBox field can be in one of the following states: empty with no pending operations -- neutral state; empty with one or more waiting take() operations pending -- deficit; occupied with no pending operations; occupied with one or more waiting put() operations -- surplus; empty with a pending put() or pending put() and take() operations -- transitional; or occupied with a pending take() or pending put() and take() operations -- transitional. The partial put() and take() operators can be implemented with an atomic fetch-and-increment operation, which may confer a performance advantage over a CAS-based loop. In addition we have independent PutCursor and TakeCursor cursors. Critically, a put() operation modifies PutCursor but does not access the TakeCursor and a take() operation modifies the TakeCursor cursor but does not access the PutCursor. This acts to reduce coherence traffic relative to some other queue designs. It's worth noting that slow threads or obstruction in one slot (or "lane") does not impede or obstruct operations in other slots -- this gives us some degree of obstruction isolation. PTLQueue is not lock-free, however. The implementation above is expressed with polite busy-waiting (Pause) but it's trivial to implement per-slot parking and unparking to deschedule waiting threads. It's also easy to convert the queue to a more general deque by replacing the PutCursor and TakeCursor cursors with Left/Front and Right/Back cursors that can move either direction. Specifically, to push and pop from the "left" side of the deque we would decrement and increment the Left cursor, respectively, and to push and pop from the "right" side of the deque we would increment and decrement the Right cursor, respectively. We used a variation of PTLQueue for message passing in our recent OPODIS 2013 paper. ul { list-style:none; padding-left:0; padding:0; margin:0; margin-left:0; } ul#myTagID { padding: 0px; margin: 0px; list-style:none; margin-left:0;} -- -- There's quite a bit of related literature in this area. I'll call out a few relevant references: Wilson's NYU Courant Institute UltraComputer dissertation from 1988 is classic and the canonical starting point : Operating System Data Structures for Shared-Memory MIMD Machines with Fetch-and-Add. Regarding provenance and priority, I think PTLQueue or queues effectively equivalent to PTLQueue have been independently rediscovered a number of times. See CB-Queue and BNPBV, below, for instance. But Wilson's dissertation anticipates the basic idea and seems to predate all the others. Gottlieb et al : Basic Techniques for the Efficient Coordination of Very Large Numbers of Cooperating Sequential Processors Orozco et al : CB-Queue in Toward high-throughput algorithms on many-core architectures which appeared in TACO 2012. Meneghin et al : BNPVB family in Performance evaluation of inter-thread communication mechanisms on multicore/multithreaded architecture Dmitry Vyukov : bounded MPMC queue (highly recommended) Alex Otenko : US8607249 (highly related). John Mellor-Crummey : Concurrent queues: Practical fetch-and-phi algorithms. Technical Report 229, Department of Computer Science, University of Rochester Thomasson : FIFO Distributed Bakery Algorithm (very similar to PTLQueue). Scott and Scherer : Dual Data Structures I'll propose an optimization left as an exercise for the reader. Say we wanted to reduce memory usage by eliminating inter-slot padding. Such padding is usually "dark" memory and otherwise unused and wasted. But eliminating the padding leaves us at risk of increased false sharing. Furthermore lets say it was usually the case that the PutCursor and TakeCursor were numerically close to each other. (That's true in some use cases). We might still reduce false sharing by incrementing the cursors by some value other than 1 that is not trivially small and is coprime with the number of slots. Alternatively, we might increment the cursor by one and mask as usual, resulting in a logical index. We then use that logical index value to index into a permutation table, yielding an effective index for use in the slot array. The permutation table would be constructed so that nearby logical indices would map to more distant effective indices. (Open question: what should that permutation look like? Possibly some perversion of a Gray code or De Bruijn sequence might be suitable). As an aside, say we need to busy-wait for some condition as follows : "while C == 0 : Pause". Lets say that C is usually non-zero, so we typically don't wait. But when C happens to be 0 we'll have to spin for some period, possibly brief. We can arrange for the code to be more machine-friendly with respect to the branch predictors by transforming the loop into : "if C == 0 : for { Pause; if C != 0 : break; }". Critically, we want to restructure the loop so there's one branch that controls entry and another that controls loop exit. A concern is that your compiler or JIT might be clever enough to transform this back to "while C == 0 : Pause". You can sometimes avoid this by inserting a call to a some type of very cheap "opaque" method that the compiler can't elide or reorder. On Solaris, for instance, you could use :"if C == 0 : { gethrtime(); for { Pause; if C != 0 : break; }}". It's worth noting the obvious duality between locks and queues. If you have strict FIFO lock implementation with local spinning and succession by direct handoff such as MCS or CLH,then you can usually transform that lock into a queue.

• C# creating a queue to handle jobs triggered by FileSystemWatcher

  - by John S

  I have built a small tray app that will watch a folder and when a new file is added it runs a job. The job is to watch for video files and convert them to .mp4 using handBrakeCli. I have all this logic worked out. The problem I run into is that if there is more than one file I want it to queue the job til the prior one is complete. I am fairly new to c# and I am not sure of the best way to handle this. one idea is to create a queue somehow, a file to store the commands in order maybe, then execute the next one after the process is complete. We are dealing with large movie files here so it can take a while. I am doing this on a quad core with 8gb of RAM and it seems to generally take about 30mins to complete a full length movie. here is the code I have so far. there are some bits in here that are for future functionality so it refers to some classes that you wont see but it doesnt matter as they arent used here. any suggestions are welcome. using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using System.IO; using System.Diagnostics; using System.Threading; namespace movie_converter { public partial class Form1 : Form { public Form1() { InitializeComponent(); } string hbCli; string cmd; string file; string strfilter = "*.*"; string[] filter = new string[3] { ".mkv", ".avi", ".wmv" }; //static list of types List<string> Ext = new List<string>(); //list of extensions to watch (dynamic) NotifyIcon notifyIcon = new System.Windows.Forms.NotifyIcon(); private void SetUpTrayIcon() { notifyIcon.BalloonTipText = "Movie Converter is running minimized."; notifyIcon.BalloonTipTitle = "I'm still here"; notifyIcon.Text = "John's movie converter"; notifyIcon.Icon = new Icon(@"C:\\Users\\John\\Pictures\\appicon.ico"); notifyIcon.Click += new EventHandler(notifyIcon_Click); if (notifyIcon != null) { notifyIcon.Visible = true; notifyIcon.ShowBalloonTip(2000); } } private void Form_Resize(object sender, EventArgs e) { if (WindowState == FormWindowState.Minimized) { this.Hide(); SetUpTrayIcon(); } } private void notifyIcon_Click(object sender, EventArgs e) { this.Show(); this.WindowState = FormWindowState.Normal; notifyIcon.Visible = false; } public void Watcher() { FileSystemWatcher watcher = new FileSystemWatcher(); watcher.Path = textBox1.Text + "\\"; //path to watch watcher.Filter = strfilter; //what types to look for set to * and i will filter later as it cant accept an array watcher.NotifyFilter = NotifyFilters.FileName | NotifyFilters.DirectoryName; //properties to look at watcher.IncludeSubdirectories = true; //scan subdirs watcher.Created += new FileSystemEventHandler(OnChanged); //TODO: make this only run if the files are of a certain type watcher.EnableRaisingEvents = true; // start the watcher } static bool IsFileLocked(FileInfo file) { FileStream stream = null; try { stream = file.Open(FileMode.Open, FileAccess.ReadWrite, FileShare.None); } catch (IOException) { //the file is unavailable because it is: //still being written to //or being processed by another thread //or does not exist (has already been processed) return true; } finally { if (stream != null) stream.Close(); } //file is not locked return false; } // Define the event handlers. private void OnChanged(object source, FileSystemEventArgs e) { string sFile = e.FullPath; //check that file is available FileInfo fileInfo = new FileInfo(sFile); while (IsFileLocked(fileInfo)) { Thread.Sleep(500); } if (System.Diagnostics.Process.GetProcessesByName("HandBrakeCLI").Length != 0) { Thread.Sleep(500); } else { //hbOptions hbCl = new hbOptions(); //hbCli = hbCl.HbCliOptions(); if (textBox3.Text != "") { hbCli = textBox3.Text.ToString(); } else { hbCli = "-e x264 -q 20 -B 160"; } string t = e.Name; string s = t.Substring(0, t.Length - 4); //TODO: fix this its not reliable file = e.FullPath; string opath = textBox1.Text.ToString(); cmd = "-i \"" + file + "\" -o \"" + opath + "\\" + s + ".mp4\" " + hbCli; try { for (int i = 0; i < Ext.Count(); i++) { if (e.Name.Contains(Ext[i])) { Process hb = new Process(); hb.StartInfo.FileName = "D:\\Apps\\Handbrake\\Install\\Handbrake\\HandBrakeCLI.exe"; hb.StartInfo.Arguments = cmd; notifyIcon.BalloonTipTitle = "Now Converting"; notifyIcon.BalloonTipText = file; notifyIcon.ShowBalloonTip(2000); hb.Start(); } } } catch (Exception ex) { MessageBox.Show(ex.Message); } } } private void button1_Click(object sender, EventArgs e) //ok button { //add each array item to the list for (int i = 0; i < filter.Count(); i++) { Ext.Add(filter[i]); } if (textBox1.Text != "" && textBox1.Text.Length > 2) { Watcher(); //call watcher to run } this.WindowState = FormWindowState.Minimized; } private void button2_Click(object sender, EventArgs e) //browse button { //broswe button DialogResult result = folderBrowserDialog1.ShowDialog(); if (result == DialogResult.OK) { textBox1.Text = folderBrowserDialog1.SelectedPath; } } private void button3_Click(object sender, EventArgs e) //commands button { Process np = new Process(); np.StartInfo.FileName = "notepad.exe"; np.StartInfo.Arguments = "hbCLI.txt"; np.Start(); } private void button4_Click(object sender, EventArgs e) //options button { hbOptions options = new hbOptions(); options.ShowDialog(); } private void button5_Click(object sender, EventArgs e) //exit button { this.Close(); } private void Form1_Load(object sender, EventArgs e) { this.Resize += Form_Resize; } } }

• Web Application Problems (web.config errors) HTTP 500.19 with IIS7.5 and ASP.NET v2

  - by Django Reinhardt

  This is driving the whole team crazy. There must be some simple mis-configured part of IIS or our Web Server, but every time we try to run out ASP.NET Web Application on IIS 7.5 we get the following error... Here's the error in full: HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid. `Detailed Error Information` Module IIS Web Core Notification Unknown Handler Not yet determined Error Code 0x8007000d Config Error Config File \\?\E:\wwwroot\web.config Requested URL http://localhost:80/Default.aspx Physical Path Logon Method Not yet determined Logon User Not yet determined Config Source -1: 0: The machine is running Windows Server 2008 R2. We're developing our Web Application using Visual Studio 2008. According to Microsoft the code 8007000d means there's a syntax error in our web.config -- except the project builds and runs fine locally. Looking at the web.config in XML Notepad doesn't bring up any syntax errors, either. I'm assuming it must be some sort of poor configuration on my part...? Does anyone know where I might find further information about the error? Nothing is showing in EventViewer, either :( Not sure what else would be helpful to mention... Assistance is greatly appreciated. Thanks! UPDATES! - POSTED WEB.CONFIG BELOW Ok, since I posted the original question above, I've tracked down the precise lines in the web.config that were causing the error. Here are the lines (they appear between <System.webServer> tags)... <httpHandlers> <remove verb="*" path="*.asmx"/> <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/> </httpHandlers> Note: If I delete the lines between the <httpHandlers> I STILL get the error. I literally have to delete <httpHandlers> (and the lines inbetween) to stop getting the above error. Once I've done this I get a new 500.19 error, however. Thankfully, this time IIS actually tells me which bit of the web.config is causing a problem... <handlers> <remove name="WebServiceHandlerFactory-Integrated"/> <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory,System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/> <add name="ScriptHandlerFactoryAppServices" verb="*" path="*_AppService.axd" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/> <add name="ScriptResource" preCondition="integratedMode" verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/> </handlers> Looking at these lines it's clear the problem has migrated further within the same <system.webServer> tag to the <handlers> tag. The new error is also more explicit and specifically complains that it doesn't recognize the attribute "validate" (as seen on the third line above). Removing this attribute then makes it complain that the same line doesn't have the required "name" attribute. Adding this attribute then brings up ASP.NET error... Could not load file or assembly 'System.web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56' or one of its dependencies. The system cannot find the file specified. Obviously I think these new errors have just arisen from me deleting the <httpHandlers> tags in the first place -- they're obviously needed by the application -- so the question remains: Why would these tags kick up an error in IIS in the first place??? Do I need to install something to IIS to make it work with them? Thanks again for any help. WEB.CONFIG Here's the troublesome bits of our web.Config... I hope this helps someone find our problem! <system.Web> <!-- stuff cut out --> <httpHandlers> <remove verb="*" path="*.asmx"/> <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/> <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/> <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56" validate="false"/> </httpHandlers> <httpModules> <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/> </httpModules> </system.web> <system.webServer> <validation validateIntegratedModeConfiguration="false"/> <modules> <add name="ScriptModule" preCondition="integratedMode" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/> </modules> <remove verb="*" path="*.asmx"/> <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/> <handlers> <remove name="WebServiceHandlerFactory-Integrated"/> <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory,System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/> <add name="ScriptHandlerFactoryAppServices" verb="*" path="*_AppService.axd" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/> <add name="ScriptResource" preCondition="integratedMode" verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=f2cb5667dc123a56"/> </handlers> </system.webServer>

• .NET file Decryption - Bad Data

  - by Jon

  I am in the process of rewriting an old application. The old app stored data in a scoreboard file that was encrypted with the following code: private const String SSecretKey = @"?B?n?Mj?"; public DataTable GetScoreboardFromFile() { FileInfo f = new FileInfo(scoreBoardLocation); if (!f.Exists) { return setupNewScoreBoard(); } DESCryptoServiceProvider DES = new DESCryptoServiceProvider(); //A 64 bit key and IV is required for this provider. //Set secret key For DES algorithm. DES.Key = ASCIIEncoding.ASCII.GetBytes(SSecretKey); //Set initialization vector. DES.IV = ASCIIEncoding.ASCII.GetBytes(SSecretKey); //Create a file stream to read the encrypted file back. FileStream fsread = new FileStream(scoreBoardLocation, FileMode.Open, FileAccess.Read); //Create a DES decryptor from the DES instance. ICryptoTransform desdecrypt = DES.CreateDecryptor(); //Create crypto stream set to read and do a //DES decryption transform on incoming bytes. CryptoStream cryptostreamDecr = new CryptoStream(fsread, desdecrypt, CryptoStreamMode.Read); DataTable dTable = new DataTable("scoreboard"); dTable.ReadXml(new StreamReader(cryptostreamDecr)); cryptostreamDecr.Close(); fsread.Close(); return dTable; } This works fine. I have copied the code into my new app so that I can create a legacy loader and convert the data into the new format. The problem is I get a "Bad Data" error: System.Security.Cryptography.CryptographicException was unhandled Message="Bad Data.\r\n" Source="mscorlib" The error fires at this line: dTable.ReadXml(new StreamReader(cryptostreamDecr)); The encrypted file was created today on the same machine with the old code. I guess that maybe the encryption / decryption process uses the application name / file or something and therefore means I can not open it. Does anyone have an idea as to: A) Be able explain why this isn't working? B) Offer a solution that would allow me to be able to open files that were created with the legacy application and be able to convert them please? Here is the whole class that deals with loading and saving the scoreboard: using System; using System.Collections.Generic; using System.Text; using System.Security.Cryptography; using System.Runtime.InteropServices; using System.IO; using System.Data; using System.Xml; using System.Threading; namespace JawBreaker { [Serializable] class ScoreBoardLoader { private Jawbreaker jawbreaker; private String sSecretKey = @"?B?n?Mj?"; private String scoreBoardFileLocation = ""; private bool keepScoreBoardUpdated = true; private int intTimer = 180000; public ScoreBoardLoader(Jawbreaker jawbreaker, String scoreBoardFileLocation) { this.jawbreaker = jawbreaker; this.scoreBoardFileLocation = scoreBoardFileLocation; } // Call this function to remove the key from memory after use for security [System.Runtime.InteropServices.DllImport("KERNEL32.DLL", EntryPoint = "RtlZeroMemory")] public static extern bool ZeroMemory(IntPtr Destination, int Length); // Function to Generate a 64 bits Key. private string GenerateKey() { // Create an instance of Symetric Algorithm.

• Silverlight 2.0 - Can't get the text wrapping behaviour that I want

  - by Anthony

  I am having trouble getting Silverlight 2.0 to lay out text exactly how I want. I want text with line breaks and embedded links, with wrapping, like HTML text in a web page. Here's the closest that I have come: <UserControl x:Class="FlowPanelTest.Page" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:Controls="clr-namespace:Microsoft.Windows.Controls;assembly=Microsoft.Windows.Controls" Width="250" Height="300"> <Border BorderBrush="Black" BorderThickness="2" > <Controls:WrapPanel> <TextBlock x:Name="tb1" TextWrapping="Wrap">Short text. </TextBlock> <TextBlock x:Name="tb2" TextWrapping="Wrap">A bit of text. </TextBlock> <TextBlock x:Name="tb3" TextWrapping="Wrap">About half of a line of text.</TextBlock> <TextBlock x:Name="tb4" TextWrapping="Wrap">More than half a line of longer text.</TextBlock> <TextBlock x:Name="tb5" TextWrapping="Wrap">More than one line of text, so it will wrap onto the following line.</TextBlock> </Controls:WrapPanel> </Border> </UserControl> But the issue is that although the text blocks tb1 and tb2 will go onto the same line because there is room enough for them completely, tb3 onwards will not start on the same line as the previous block, even though it will wrap onto following lines. I want each text block to start where the previous one ends, on the same line. I want to put click event handlers on some of the text. I also want paragraph breaks. Essentially I'm trying to work around the lack of FlowDocument and Hyperlink controls in Silverlight 2.0's subset of XAML. To answer the questions posed in the answers: Why not use runs for the non-clickable text? If I just use individual TextBlocks only on the clickable text, then those bits of text will still suffer from the wrapping problem illustrated above. And the TextBlock just before the link, and the TextBlock just after. Essentially all of it. It doesn't look like I have many opportunities for putting multiple runs in the same TextBlock. Dividing the links from the other text with RegExs and loops is not the issue at all, the issue is display layout. Why not put each word in an individual TextBlock in a WrapPanel Aside from being an ugly hack, this does not play at all well with linebreaks - the layout is incorrect. It would also make the underline style of linked text into a broken line. Here's an example with each word in its own TextBlock. Try running it, note that the linebreak isn't shown in the right place at all. <UserControl x:Class="SilverlightApplication2.Page" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:Controls="clr-namespace:Microsoft.Windows.Controls;assembly=Microsoft.Windows.Controls" Width="300" Height="300"> <Controls:WrapPanel> <TextBlock TextWrapping="Wrap">Short1 </TextBlock> <TextBlock TextWrapping="Wrap">Longer1 </TextBlock> <TextBlock TextWrapping="Wrap">Longerest1 </TextBlock> <TextBlock TextWrapping="Wrap"> <Run>Break</Run> <LineBreak></LineBreak> </TextBlock> <TextBlock TextWrapping="Wrap">Short2</TextBlock> <TextBlock TextWrapping="Wrap">Longer2</TextBlock> <TextBlock TextWrapping="Wrap">Longerest2</TextBlock> <TextBlock TextWrapping="Wrap">Short3</TextBlock> <TextBlock TextWrapping="Wrap">Longer3</TextBlock> <TextBlock TextWrapping="Wrap">Longerest3</TextBlock> </Controls:WrapPanel> </UserControl> What about The LinkLabelControl as here and here. It has the same problems as the approach above, since it's much the same. Try running the sample, and make the link text longer and longer until it wraps. Note that the link starts on a new line, which it shouldn't. Make the link text even longer, so that the link text is longer than a line. Note that it doesn't wrap at all, it cuts off. This control doesn't handle line breaks and paragraph breaks either. Why not put the text all in runs, detect clicks on the containing TextBlock and work out which run was clicked Runs do not have mouse events, but the containing TextBlock does. I can't find a way to check if the run is under the mouse (IsMouseOver is not present in SilverLight) or to find the bounding geometry of the run (no clip property). There is VisualTreeHelper.FindElementsInHostCoordinates() The code below uses VisualTreeHelper.FindElementsInHostCoordinates to get the controls under the click. The output lists the TextBlock but not the Run, since a Run is not a UiElement. private void theText_MouseLeftButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e) { // get the elements under the click UIElement uiElementSender = sender as UIElement; Point clickPos = e.GetPosition(uiElementSender); var UiElementsUnderClick = VisualTreeHelper.FindElementsInHostCoordinates(clickPos, uiElementSender); // show the controls string outputText = ""; foreach (var uiElement in UiElementsUnderClick) { outputText += uiElement.GetType().ToString() + "\n"; } this.outText.Text = outputText; } Use an empty text block with a margin to space following content onto a following line I'm still thinking about this one. How do you calculate the right width for a line-breaking block to force following content onto the following line? Too short and the following content will still be on the same line, at the right. Too long and the "linebreak" will be on the following line, with content after it. You would have to resize the breaks when the control is resized. Some of the code for this is: TextBlock lineBreak = new TextBlock(); lineBreak.TextWrapping = TextWrapping.Wrap; lineBreak.Text = " "; // need adaptive width lineBreak.Margin = new Thickness(0, 0, 200, 0);

• ASP.NET Creating a Rich Repeater, DataBind wiping out custom added controls...

  - by tonyellard

  So...I had this clever idea that I'd create my own Repeater control that implements paging and sorting by inheriting from Repeater and extending it's capabilities. I found some information and bits and pieces on how to go about this and everything seemed ok... I created a WebControlLibrary to house my custom controls. Along with the enriched repeater, I created a composite control that would act as the "pager bar", having forward, back and page selection. My pager bar works 100% on it's own, properly firing a paged changed event when the user interacts with it. The rich repeater databinds without issue, but when the databind fires (when I call base.databind()), the control collection is cleared out and my pager bars are removed. This screws up the viewstate for the pager bars making them unable to fire their events properly or maintain their state. I've tried adding the controls back to the collection after base.databind() fires, but that doesn't solve the issue. I start to get very strange results including problems with altering the hierarchy of the control tree (resolved by adding [ViewStateModeById]). Before I go back to the drawing board and create a second composite control which contains a repeater and the pager bars (so that the repeater isn't responsible for the pager bars viewstate) are there any thoughts about how to resolve the issue? In the interest of share and share alike, the code for the repeater itself is below, the pagerbars aren't as significant as the issue is really the maintaining of state for any additional child controls. (forgive the roughness of some of the code...it's still a work in progress) using System; using System.Collections.Generic; using System.ComponentModel; using System.Text; using System.Data; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; [ViewStateModeById] public class SortablePagedRepeater : Repeater, INamingContainer { private SuperRepeaterPagerBar topBar = new SuperRepeaterPagerBar(); private SuperRepeaterPagerBar btmBar = new SuperRepeaterPagerBar(); protected override void OnInit(EventArgs e) { Page.RegisterRequiresControlState(this); InitializeControls(); base.OnInit(e); EnsureChildControls(); } protected void InitializeControls() { topBar.ID = this.ID + "__topPagerBar"; topBar.NumberOfPages = this._currentProperties.numOfPages; topBar.CurrentPage = this.CurrentPageNumber; topBar.PageChanged += new SuperRepeaterPagerBar.PageChangedEventHandler(PageChanged); btmBar.ID = this.ID + "__btmPagerBar"; btmBar.NumberOfPages = this._currentProperties.numOfPages; btmBar.CurrentPage = this.CurrentPageNumber; btmBar.PageChanged += new SuperRepeaterPagerBar.PageChangedEventHandler(PageChanged); } protected override void CreateChildControls() { EnsureDataBound(); this.Controls.Add(topBar); this.Controls.Add(btmBar); //base.CreateChildControls(); } private void PageChanged(object sender, int newPage) { this.CurrentPageNumber = newPage; } public override void DataBind() { //pageDataSource(); //DataBind removes all controls from control collection... base.DataBind(); Controls.Add(topBar); Controls.Add(btmBar); } private void pageDataSource() { //Create paged data source PagedDataSource pds = new PagedDataSource(); pds.PageSize = this.ItemsPerPage; pds.AllowPaging = true; // first get a PagedDataSource going and perform sort if possible... if (base.DataSource is System.Collections.IEnumerable) { pds.DataSource = (System.Collections.IEnumerable)base.DataSource; } else if (base.DataSource is System.Data.DataView) { DataView data = (DataView)DataSource; if (this.SortBy != null && data.Table.Columns.Contains(this.SortBy)) { data.Sort = this.SortBy; } pds.DataSource = data.Table.Rows; } else if (base.DataSource is System.Data.DataTable) { DataTable data = (DataTable)DataSource; if (this.SortBy != null && data.Columns.Contains(this.SortBy)) { data.DefaultView.Sort = this.SortBy; } pds.DataSource = data.DefaultView; } else if (base.DataSource is System.Data.DataSet) { DataSet data = (DataSet)DataSource; if (base.DataMember != null && data.Tables.Contains(base.DataMember)) { if (this.SortBy != null && data.Tables[base.DataMember].Columns.Contains(this.SortBy)) { data.Tables[base.DataMember].DefaultView.Sort = this.SortBy; } pds.DataSource = data.Tables[base.DataMember].DefaultView; } else if (data.Tables.Count > 0) { if (this.SortBy != null && data.Tables[0].Columns.Contains(this.SortBy)) { data.Tables[0].DefaultView.Sort = this.SortBy; } pds.DataSource = data.Tables[0].DefaultView; } else { throw new Exception("DataSet doesn't have any tables."); } } else if (base.DataSource == null) { // don't do anything? } else { throw new Exception("DataSource must be of type System.Collections.IEnumerable.

• Convert flyout menu to respond onclick vs mouseover

• TSQL Conditionally Select Specific Value

  - by Dzejms

  This is a follow-up to #1644748 where I successfully answered my own question, but Quassnoi helped me to realize that it was the wrong question. He gave me a solution that worked for my sample data, but I couldn't plug it back into the parent stored procedure because I fail at SQL 2005 syntax. So here is an attempt to paint the broader picture and ask what I actually need. This is part of a stored procedure that returns a list of items in a bug tracking application I've inherited. There are are over 100 fields and 26 joins so I'm pulling out only the mostly relevant bits. SELECT tickets.ticketid, tickets.tickettype, tickets_tickettype_lu.tickettypedesc, tickets.stage, tickets.position, tickets.sponsor, tickets.dev, tickets.qa, DATEDIFF(DAY, ticket_history_assignment.savedate, GETDATE()) as 'daysinqueue' FROM dbo.tickets WITH (NOLOCK) LEFT OUTER JOIN dbo.tickets_tickettype_lu WITH (NOLOCK) ON tickets.tickettype = tickets_tickettype_lu.tickettypeid LEFT OUTER JOIN dbo.tickets_history_assignment WITH (NOLOCK) ON tickets_history_assignment.ticketid = tickets.ticketid AND tickets_history_assignment.historyid = ( SELECT MAX(historyid) FROM dbo.tickets_history_assignment WITH (NOLOCK) WHERE tickets_history_assignment.ticketid = tickets.ticketid GROUP BY tickets_history_assignment.ticketid ) WHERE tickets.sponsor = @sponsor The area of interest is the daysinqueue subquery mess. The tickets_history_assignment table looks roughly as follows declare @tickets_history_assignment table ( historyid int, ticketid int, sponsor int, dev int, qa int, savedate datetime ) insert into @tickets_history_assignment values (1521402, 92774,20,14, 20, '2009-10-27 09:17:59.527') insert into @tickets_history_assignment values (1521399, 92774,20,14, 42, '2009-08-31 12:07:52.917') insert into @tickets_history_assignment values (1521311, 92774,100,14, 42, '2008-12-08 16:15:49.887') insert into @tickets_history_assignment values (1521336, 92774,100,14, 42, '2009-01-16 14:27:43.577') Whenever a ticket is saved, the current values for sponsor, dev and qa are stored in the tickets_history_assignment table with the ticketid and a timestamp. So it is possible for someone to change the value for qa, but leave sponsor alone. What I want to know, based on all of these conditions, is the historyid of the record in the tickets_history_assignment table where the sponsor value was last changed so that I can calculate the value for daysinqueue. If a record is inserted into the history table, and only the qa value has changed, I don't want that record. So simply relying on MAX(historyid) won't work for me. Quassnoi came up with the following which seemed to work with my sample data, but I can't plug it into the larger query, SQL Manager bitches about the WITH statement. ;WITH rows AS ( SELECT *, ROW_NUMBER() OVER (PARTITION BY ticketid ORDER BY savedate DESC) AS rn FROM @Table ) SELECT rl.sponsor, ro.savedate FROM rows rl CROSS APPLY ( SELECT TOP 1 rc.savedate FROM rows rc JOIN rows rn ON rn.ticketid = rc.ticketid AND rn.rn = rc.rn + 1 AND rn.sponsor <> rc.sponsor WHERE rc.ticketid = rl.ticketid ORDER BY rc.rn ) ro WHERE rl.rn = 1 I played with it yesterday afternoon and got nowhere because I don't fundamentally understand what is going on here and how it should fit into the larger context. So, any takers? UPDATE Ok, here's the whole thing. I've been switching some of the table and column names in an attempt to simplify things so here's the full unedited mess. snip - old bad code Here are the errors: Msg 102, Level 15, State 1, Procedure usp_GetProjectRecordsByAssignment, Line 159 Incorrect syntax near ';'. Msg 102, Level 15, State 1, Procedure usp_GetProjectRecordsByAssignment, Line 179 Incorrect syntax near ')'. Line numbers are of course not correct but refer to ;WITH rows AS And the ')' char after the WHERE rl.rn = 1 ) Respectively Is there a tag for extra super long question?

• SocketChannel in Java sends data, but it doesn't get to destination application

  - by Peterson

  Hi Everybody, I'm suffering a lot to create a simple ChatServer in Java, using the NIO libraries. Wonder if someone could help me. I am doing that by using SocketChannel and Selector to handle multiple clients in a single thread. The problem is: I am able to accept new connections and get it's data, but when I try to send data back, the SocketChannel simply doesn't work. In the method write(), it returns a integer that is the same size of the data i'm passing to it, but the client never receives that data. Strangely, when I close the server application, the client receives the data. It's like the socketchannel maintains a buffer, and it only get flushed when I close the application. Here are some more details, to give you more information to help. I'm handling the events in this piece of code: private void run() throws IOException { ServerSocketChannel ssc = ServerSocketChannel.open(); // Set it to non-blocking, so we can use select ssc.configureBlocking( false ); // Get the Socket connected to this channel, and bind it // to the listening port this.serverSocket = ssc.socket(); InetSocketAddress isa = new InetSocketAddress( this.port ); serverSocket.bind( isa ); // Create a new Selector for selecting this.masterSelector = Selector.open(); // Register the ServerSocketChannel, so we can // listen for incoming connections ssc.register( masterSelector, SelectionKey.OP_ACCEPT ); while (true) { // See if we've had any activity -- either // an incoming connection, or incoming data on an // existing connection int num = masterSelector.select(); // If we don't have any activity, loop around and wait // again if (num == 0) { continue; } // Get the keys corresponding to the activity // that has been detected, and process them // one by one Set keys = masterSelector.selectedKeys(); Iterator it = keys.iterator(); while (it.hasNext()) { // Get a key representing one of bits of I/O // activity SelectionKey key = (SelectionKey)it.next(); // What kind of activity is it? if ((key.readyOps() & SelectionKey.OP_ACCEPT) == SelectionKey.OP_ACCEPT) { // Aceita a conexão Socket s = serverSocket.accept(); System.out.println( "LOG: Conexao TCP aceita de " + s.getInetAddress() + ":" + s.getPort() ); // Make sure to make it non-blocking, so we can // use a selector on it. SocketChannel sc = s.getChannel(); sc.configureBlocking( false ); // Registra a conexao no seletor, apenas para leitura sc.register( masterSelector, SelectionKey.OP_READ ); } else if ( key.isReadable() ) { SocketChannel sc = null; // It's incoming data on a connection, so // process it sc = (SocketChannel)key.channel(); // Verifica se a conexão corresponde a um cliente já existente if((clientsMap.getClient(key)) != null){ boolean closedConnection = !processIncomingClientData(key); if(closedConnection){ int id = clientsMap.getClient(key); closeClient(id); } } else { boolean clientAccepted = processIncomingDataFromNewClient(key); if(!clientAccepted){ // Se o cliente não foi aceito, sua conexão é simplesmente fechada sc.socket().close(); sc.close(); key.cancel(); } } } } // We remove the selected keys, because we've dealt // with them. keys.clear(); } } This piece of code is simply handles new clients that wants to connect to the chat. So, a client makes a TCP connection to the server, and once it gets accepted, it sends data to the server following a simply text protocol, informing his id and asking to get registrated to the server. I handle this in the method processIncomingDataFromNewClient(key). I'm also keeping a map of clients and its connections in a data structure similar to a hashtable. I? doing that because I need to recover a client Id from a connection and a connection from a client Id. This is can be shown in: clientsMap.getClient(key). But the problem itself resides in the method processIncomingDataFromNewClient(key). There, I simply read the data that the client sent to me, validate it, and if it's ok, I send a message back to the client to tell that it is connected to the chat server. Here is a similar piece of code: private boolean processIncomingDataFromNewClient(SelectionKey key){ SocketChannel sc = (SocketChannel) key.channel(); String connectionOrigin = sc.socket().getInetAddress() + ":" + sc.socket().getPort(); int id = 0; //id of the client buf.clear(); int bytesRead = 0; try { bytesRead = sc.read(buf); if(bytesRead<=0){ System.out.println("Conexão fechada pelo: " + connectionOrigin); return false; } System.out.println("LOG: " + bytesRead + " bytes lidos de " + connectionOrigin); String msg = new String(buf.array(),0,bytesRead); // Do validations with the client sent me here // gets the client id }catch (Exception e) { e.printStackTrace(); System.out.println("LOG: Oops. Cliente não conhece o protocolo. Fechando a conexão: " + connectionOrigin); System.out.println("LOG: Primeiros 10 caracteres enviados pelo cliente: " + msg); return false; } } } catch (IOException e) { System.out.println("LOG: Erro ao ler dados da conexao: " + connectionOrigin); System.out.println("LOG: "+ e.getLocalizedMessage()); System.out.println("LOG: Fechando a conexão..."); return false; } // If it gets to here, the protocol is ok and we can add the client boolean inserted = clientsMap.addClient(key, id); if(!inserted){ System.out.println("LOG: Não foi possível adicionar o cliente. Ou ele já está conectado ou já têm clientes demais. Id: " + id); System.out.println("LOG: Fechando a conexão: " + connectionOrigin); return false; } System.out.println("LOG: Novo cliente conectado! Enviando mesnsagem de confirmação. Id: " + id + " Conexao: " + connectionOrigin); /* Here is the error */ sendMessage(id, "Servidor pet: connection accepted"); System.out.println("LOG: Novo cliente conectado! Id: " + id + " Conexao: " + connectionOrigin); return true; } And finally, the method sendMessage(SelectionKey key) looks like this: private void sendMessage(int destId, String msg) { Charset charset = Charset.forName("ISO-8859-1"); CharBuffer charBuffer = CharBuffer.wrap(msg, 0, msg.length()); ByteBuffer bf = charset.encode(charBuffer); //bf.flip(); int bytesSent = 0; SelectionKey key = clientsMap.getClient(destId); SocketChannel sc = (SocketChannel) key.channel(); try { / int total_bytes_sent = 0; while(total_bytes_sent < msg.length()){ bytesSent = sc.write(bf); total_bytes_sent += bytesSent; } System.out.println("LOG: Bytes enviados para o cliente " + destId + ": "+ total_bytes_sent + " Tamanho da mensagem: " + msg.length()); } catch (IOException e) { System.out.println("LOG: Erro ao mandar mensagem para: " + destId); System.out.println("LOG: " + e.getLocalizedMessage()); } } So, what is happening is that the server, when send a message, prints something like this: LOG: Bytes sent to the client: 28 Size of the message: 28 So, it tells that it sent the data, but the chat client keeps blocking, waiting in the recv() method. So, the data never gets to it. When I close the server application, though, all the data appears in the client. I wonder why. It is important to say that the client is in C and the server JAVA, and I'm running both in the same machine, an Ubuntu Guest in virtualbox under windows. I also run both under windows host and under linuxes hosts, and keep getting the same strange problem. I'm sorry for the great lenght of this question, but I already searched a lot of places for an answer, found a lot of tutorials and questions, including here at StackOverflow, but coundn't find a reasonable explanation. I am really not liking this Java NIO, and i saw a lot of people complaining about it too. I am thinking that if I had done that in C it would have been a lot easier :-D So, if someone could help me and even discuss this behavor, it would be great! :-) Thanks everybody in advance, Péterson
