• How to interpret kernel panics?

  - by Owen

  Hi all, I'm new to linux kernel and could barely understand how to debug kernel panics. I have this error below and I don't know where in the C code should I start checking. I was thinking maybe I could echo what functions are being called so I could check where in the code is this null pointer dereferenced. What print function should I use ? How do you interpret the error message below?

• How to support udev in a kernel module?

  - by Basilevs

  I'm porting a linux kernel module. It used to create a device file for itself (using dirty hacks with syscalls from kernelspace), but now I want to do this in udev. Where can I find documentation on supporting udev in in kernel module? Note that module itself is not a device driver. It serves as a multiplexor for a set of drivers. Therefor default ways of registering devices (i.e. pci ones) are not suitable for my task.

• Recursively disabling CONFIG dependencies on linux kernel builds

  - by Corey Henderson

  When configuring a Linux kernel, I normally start with my distribution's kernel config file. I often want to turn off some entries, but they are sometimes unchangeable because other CONFIG options that depend on it are enabled. I can look up the dependencies manually, which often have dependencies of their own. It can be pretty time consuming to did through them all, especially if you're trying to turn off something like CONFIG_KALLSYMS. Is there a way to specify a CONFIG option you want gone, and have all dependencies automatically selected/disselected as nessisary for you? I looked through all the make options and in the scripts directory, and didn't see anything available for this.

• Kernel dealing with the section headers in an ELF

  - by uki

  I recently read that the kernel and the dynamic loader mostly deal with the program header tables in an ELF file and that assemblers, compilers and linkers deal with the section header tables. The number of program header tables and section header tables are mentioned in the ELF header in fields named e_phnum and e_shnum respectively. e_phnum is two bytes in size, so if the number of program headers is 65535, we use a scheme known as extended numbering where, e_phnum is set to 0xffff and sh_link field of the zeroth section header table holds the actual count. My doubt is : If the count of program headers exceeds 65535, does that mean the kernel and/or the dynamic loader end up having to read the section table?

• How do I determine if my controller is in IDE or AHCI mode in Linux?

  - by philcolbourn

  I have an old MacBook Pro 4,1 (early 2008) - but I suspect an answer would apply to many MacBook Pros. It has an Intel IDE/SATA controller (ICH8M/ICH8M-E). I have installed a patched MBR that is supposed to put my controller into AHCI mode. It does this by setting some controller port value that I don't understand. This seems to work as I get this from lspci: 00:1f.1 IDE interface: Intel Corporation 82801HM/HEM (ICH8M/ICH8M-E) IDE Controller (rev 03) 00:1f.2 IDE interface: Intel Corporation 82801HM/HEM (ICH8M/ICH8M-E) SATA Controller [AHCI mode] (rev 03) Now most, perhaps all, sites that provide a solution (enabling AHCI) suggest that after a sleep/wake cycle that a controller will revert to IDE mode due to how Apple support Windows. They recommend disabling sleep. From author of patchedcode.bin I think Enabling AHCI for Windows on MacBooks NB: I do not have bootcamp installed and I do not have Windows installed. Is there a way to prove that my controller is in IDE or AHCI mode? Background Data Using patchedcode.bin MBR I get this in syslog: Jun 12 22:33:22 max kernel: [ 1.860955] ahci 0000:00:1f.2: version 3.0 Jun 12 22:33:22 max kernel: [ 1.861052] ahci 0000:00:1f.2: irq 45 for MSI/MSI-X Jun 12 22:33:22 max kernel: [ 1.861117] ahci 0000:00:1f.2: AHCI 0001.0100 32 slots 3 ports 1.5 Gbps 0x1 impl SATA mode Jun 12 22:33:22 max kernel: [ 1.861120] ahci 0000:00:1f.2: flags: 64bit ncq sntf pm led clo pio slum part ccc ems Jun 12 22:33:22 max kernel: [ 1.861130] ahci 0000:00:1f.2: setting latency timer to 64 Jun 12 22:33:22 max kernel: [ 1.880880] ACPI: Video Device [GFX0] (multi-head: yes rom: no post: no) Jun 12 22:33:22 max kernel: [ 1.880983] scsi2 : ahci Jun 12 22:33:22 max kernel: [ 1.884552] scsi3 : ahci Jun 12 22:33:22 max kernel: [ 1.886932] scsi4 : ahci Jun 12 22:33:22 max kernel: [ 1.886998] ata3: SATA max UDMA/133 abar m2048@0xdb504000 port 0xdb504100 irq 45 Jun 12 22:33:22 max kernel: [ 1.887000] ata4: DUMMY Jun 12 22:33:22 max kernel: [ 1.887002] ata5: DUMMY Jun 12 22:33:22 max kernel: [ 2.204103] ata3: SATA link up 1.5 Gbps (SStatus 113 SControl 300) Jun 12 22:33:22 max kernel: [ 2.204656] ata3.00: ATA-8: FUJITSU MHY2200BH, 0081000D, max UDMA/100 Jun 12 22:33:22 max kernel: [ 2.204662] ata3.00: 390721968 sectors, multi 16: LBA48 NCQ (depth 31/32), AA Jun 12 22:33:22 max kernel: [ 2.205324] ata3.00: configured for UDMA/100 Jun 12 22:33:22 max kernel: [ 2.205554] scsi 2:0:0:0: Direct-Access ATA FUJITSU MHY2200B 0081 PQ: 0 ANSI: 5 Using my original MBR I get this from syslog: Jun 13 18:07:13 max kernel: [ 0.622861] ata_piix 0000:00:1f.1: version 2.13 Jun 13 18:07:13 max kernel: [ 0.622869] ata_piix 0000:00:1f.1: power state changed by ACPI to D0 Jun 13 18:07:13 max kernel: [ 0.622924] ata_piix 0000:00:1f.1: setting latency timer to 64 Jun 13 18:07:13 max kernel: [ 0.623339] scsi0 : ata_piix Jun 13 18:07:13 max kernel: [ 0.623730] scsi1 : ata_piix Jun 13 18:07:13 max kernel: [ 0.623765] ata1: PATA max UDMA/100 cmd 0x8108 ctl 0x811c bmdma 0x80e0 irq 21 Jun 13 18:07:13 max kernel: [ 0.623767] ata2: PATA max UDMA/100 cmd 0x8100 ctl 0x8118 bmdma 0x80e8 irq 21 Jun 13 18:07:13 max kernel: [ 0.623810] ata_piix 0000:00:1f.2: MAP [ Jun 13 18:07:13 max kernel: [ 0.623811] P0 -- -- -- ] Jun 13 18:07:13 max kernel: [ 0.623866] ata_piix 0000:00:1f.2: setting latency timer to 64 Jun 13 18:07:13 max kernel: [ 0.624241] scsi2 : ata_piix Jun 13 18:07:13 max kernel: [ 0.624558] scsi3 : ata_piix Jun 13 18:07:13 max kernel: [ 0.624862] ata3: SATA max UDMA/133 cmd 0x80f8 ctl 0x8114 bmdma 0x8020 irq 18 Jun 13 18:07:13 max kernel: [ 0.624865] ata4: SATA max UDMA/133 cmd 0x80f0 ctl 0x8110 bmdma 0x8028 irq 18 Jun 13 18:07:13 max kernel: [ 1.208879] ata3.00: ATA-8: FUJITSU MHY2200BH, 0081000D, max UDMA/100 Jun 13 18:07:13 max kernel: [ 1.208882] ata3.00: 390721968 sectors, multi 16: LBA48 NCQ (depth 0/32) Jun 13 18:07:13 max kernel: [ 1.208961] ata1.01: ATAPI: MATSHITA DVD+/-RW UJ-867S, 1.00, max UDMA/33 Jun 13 18:07:13 max kernel: [ 1.216186] ata3.00: configured for UDMA/100 Jun 13 18:07:13 max kernel: [ 1.224396] ata1.01: configured for UDMA/33

• mmap only needed pages of kernel buffer to user space

  - by axeoth

  See also this answer: http://stackoverflow.com/a/10770582/1284631 I need something similar, but without having to allocate a buffer: the buffer is large, in theory, but the user space program only needs to access some parts of it (it mocks some registers of a hardware). As I cannot allocate with vmalloc_user() such a large buffer (kernel 32 bit, in embedded environment, no swap...), I followed the same approach as in the quoted answer, trying to allocate only those pages that are really requested by the user space. So: I use a my_mmap() function for the device file (actually, is the .mmap field of a struct uio_info) to set up the fields of the vma, then, in the vm_area_struct's .fault field (also named my_fault()), I should return a page. except that: In the my_fault() method of vm_area_struct, I cannot obtain a page through: vmf->page=vmalloc_to_page(my_buf + (vmf->pgoff << PAGE_SHIFT)); since there is no allocated buffer: my_buf = vmalloc_user(MY_BUF_SIZE); fails with "allocation failed: out of vmalloc space - use vmalloc= to increase size." (and there is no room or swap to increase that vmalloc= parameter). So, I would need to get a page from the kernel and fill the vmf->page field. How to allocate a page (I assume that the offset of the page is known, as it is vm->pgoff). What base memory should I use instead of my_buf? PS: I also did set up the vma->flags |= VM_NORESERVE; (in the my_mmap()), but not sure if it helps. Is there any vmalloc_user_unreserved()-like function? (let's say, lazy allocation) Also, writing 1 to /proc/sys/vm/overcommit_memory and large values (eg 500) to /proc/sys/vm/overcommit_ratio before trying to my_buf=vmalloc_user(<large_size>) didn't work.

• Finding right bug tracker web application

  - by FullmetalBoy

  I'm looking for a bug tracking system (similiar as http://www.mantisbt.org) with these following requirements: Requirement specifications are: Upload picture and different files without any limitaton of the file's space. If user belong to a specific group or businesss group, the GUI:s logotype should be changed into group's logotype after the user has entered user name and password. All user use the same database with different GUI. Right information of unassigned, modified and resolved bug case will be displayed based on what group or business group that the user is assigned to. All information will display after the user has logged in. Enable to create 1 or more super user (administrator) and regular user. Right user with right group or business group will retrieve right information. Non functional requirement: The bugging tracker take place in a webbapplication. All information must use web browser to view all information.

• Presenting agile estimates for Pivotal Tracker project

  - by Tom Styles

  I've been developing for 6-7 years but never in a particularly agile way. With the latest project I'm trying to make our development process more professional, and more agile. We're using Pivotal Tracker to track the project and have gathered some pretty well thought out stories. We're also trying to keep some of our (Prince2/Waterfall mindset) project managers happy. So far I've got them to accept that requirements always change priorities always change some of the requirements won't be delivered if you fix the time scale you should fix the time scale short sprints and regular review is good However they still feel like they need to get a better grip of roughly how much will be delivered within a certain time. I've come up with a spreadsheet to demonstrate what we might expect to get done in a range of 4 different timescales. Questions Are we setting ourselves up to fail Are there better ways to do this

• Personal/career objectives tracker

  - by scottyab

  Looking for a simple, clean and easy to use personal/career objectives tracker for my team of ~10 developers something like what remember the milk is for tasks. At the moment I track these in a google doc, but ideally like a system where I can browse the teams objectives, add a team objective and it automatically appear on members personal objectives. Also where team members can add/manage their own objectives, browse colleges public/team objectives. Ideally it would also have option for people to add personal out side of work objectives for personal dev projects. Anyone used a tool to do this? our a combination of existing tools like gdocs, rtm?

• Ubuntu 12.10 with kernel 3.5.0-18

  - by Chaitanya

  I had ubuntu 12.04 with kernel 3.0.2. Today I have updated my system and got 12.10 with kernel 3.5.0-18. Now when I boot my machine with 3.5 kernel, it starts until the page where I enter my password. Within seconds, I get a page with looooong list of some commands or list. I cant take screenshot of that. It looks something like, [1.2234978942837]kjsahfa;lsfksld;fkjsf;owieurwirejw/rnw;erkjwelrjw2309480432 [1.3294823498230948]as;lfjsf;iuwrijrwjlkerjw;rekwer;lkwjre;lkjRIJWEORIWE'JJA; something like this. Luckily, in my boot page, I have 3.0.2 kernel also. When I boot with 3.0.2 kernel there is no problem. But when I boot with 3.5.0, it throws that wierd error. I wont be able to do anything at that time. None of the keys work. I have to forcibly shutdown the machine and restart with 3.0.2 kernel. Please help..... Thanks, Chaitanya.

• how to acess and change variable of kernel space from user space

  - by bhavin

  i, I have posted query previously and i am repeating same I want to modify igmpv3 (Linux) which is inbuilt in kernel2.6.-- such that it reads a value from a file and appropriately decides reserved(res 1) value inside the igmpv3 paket which is sent by a host. I want to add more to above question by saying that this is more a generic question of changing variable of kernel space from user space. Thanks in advance for your help. Regards, Bhavin

• Processor affinity settings for Linux kernel modules?

  - by Stephen Pape

  In Windows, I can set the processor affinity of driver code using KeSetSystemAffinityThread, and check which processor my code is running on using KeGetCurrentProcessorNumber. I'm trying to do something similar in a Linux kernel module, but the only affinity calls I can see are for userland processes. Is there any way to do this, so that I can run assembly code on a specific processor? (i.e. sgdt)

• Kernel error causing cpu to go into shutdown state

  - by EpsilonVector

  What kind of Kernel error can cause the cpu to go into a shut down state? I'm doing a homework assignment in OS, and we did changes in sched.c (adding a new scheduling policy, which involved ading another prio_array to the queue and switching between them when needed). Processes using this policy cause the cpu to enter a shut down state when they finish. Any suggestions where to look?

• walking list in KDB/kernel debugger

  - by user291849

  I need to walk a link list in the kernel debugger. How can I determine the head pointer and walk the list? I have a listing and can find the address and location in the code where I check to see if I have a head, so I know the specific code location and address. But not sure how to determine the pointer or how to determine the next element and pointer on the list.
