[opensuse-kernel] [patch #2 0/5] scripts/sequence-patch.sh: Add some useful options
by Jeff Mahoney 05 Oct '11

05 Oct '11

Hi all - There are a few things I do every time I expand the source tree with sequence-patch.sh. Or, rather, things I should do and forget to do a lot. The first I always remember to do: Copy the config I want to test with to my build directory. The second I forget more often than not: Expand the kABI references into my build directory. One of the things that bites me occasionally is when there are kABI changes that go un-noticed until the automated build checker flags them and sends me an email yelling at me for my carelessness. This patch adds three options to scripts/sequence-patch.sh to take care of these automatically. --build-dir=PATH allows you to specify the build directory you'll be using. It will create the directory if it doesn't exist. It defaults to $PATCH_DIR. --config=ARCH-FLAVOR allows you to specify the config you'll use. It will copy the config to your build directory. It is not a fatal error if the config does not exist. It will just not copy one. --kabi allows you to direct sequence-patch to expand the kABI references into your build directory. Since the references are arch/flavor specific, it depends on --config=ARCH-FLAVOR. It is not a fatal error if the kABI reference doesn't exist since this is always the case in the master branch. The --build-dir PATH is subject to shell expansion. It is expanded late enough in the script that most variables should be available. There are also three new variables available when --config is used: $CONFIG contains the --config contents. $CONFIG_ARCH contains the arch part of the config. $CONFIG_FLAVOR contains the flavor part. For reference, I have this in my .bashrc: export SEQUENCE_PATCH_ARGS="--config=x86_64-desktop --build-dir=~/src/scratch/build/\$CONFIG_ARCH/linux-\$SRCVERSION-\$TAG-\$CONFIG_FLAVOR --kabi" I've also added patches for --ctags and --cscope which will automatically generate the databases for either of those tools in the build directory after the source tree is expanded. - Issues addressed in patchset #2: - Help text is now a here document for easy addition of more documentation - Explanation of which variables are allowed by --build-dir - Missing rpm/modversions script is not an error on older branches - Missing symvers files are not errors - Uses true/false for simple feature flags -Jeff -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org

[opensuse-kernel] TOMOYO for 12.1?
by Marcus Meissner 22 Jul '11

22 Jul '11

Hi, Folks in #opensuse-security were asking what stops TOMOYO from being enabled in newer kernels. FATE#310292 https://bugzilla.novell.com/show_bug.cgi?id=668381 Not sure what the issue is with enabling it.

[opensuse-kernel] preload-kmp madness
by Ismail Doenmez 30 Jun '11

30 Jun '11

Hi; Everytime kernel is updated I see something similar to this: Problem: preload-kmp-desktop-1.2_k3.0.0_rc3_3-66.7.x86_64 requires kernel-desktop = 3.0.rc3-3, but this requirement cannot be provided deleted providers: kernel-desktop-3.0.rc3-3.1.x86_64 Solution 1: do not keep preload-kmp-desktop-1.2_k3.0.0_rc3_3-66.7.x86_64 installed Solution 2: do not install kernel-desktop-3.0.rc4-2.2.x86_64 Solution 3: break preload-kmp-desktop by ignoring some of its dependencies Choose from above solutions by number or cancel [1/2/3/c] (c): I think preload-kmp is the system similar to DKMS, is there any work going to replace kmp with DKMS which I _think_ (maybe naively?) would create less update problems?

[opensuse-kernel] What Solves the BNC#673944?
by Andi Sugandi 25 Jun '11

25 Jun '11

Hi developers! Is the Bug #673944[0] related to Linux kernel or just (vendor) hardware's fault (bios, acpi?) ? If it is about the kernel, then what part of the kernel that "solves" the issue (c#9)? Thanks in advance. [0] https://bugzilla.novell.com/show_bug.cgi?id=673944 Best regards, -- Andi Sugandi.

[opensuse-kernel] Disable autoloading of staging drivers?
by Stefan Seyfried 16 Jun '11

16 Jun '11

Hi all, after I found today that with 3.0-rc2 the "mei" module successfully prevents suspend with [39736.728116] pci_pm_suspend(): mei_pci_suspend+0x0/0xc0 [mei] returns 9999 I was wondering if it is a good idea to autoload staging drivers :-) mei being a staging driver and 3.0-rc2 being ancient, I have not yet opened a bug on LKML. I have, however, looked at the code and could not find out where the 9999 come from... -- Stefan Seyfried "Dispatch war rocket Ajax to bring back his body!" -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org

Hi: In current kernel head there is an entry in sysctl.conf-3.0.0-rc2-1-default that says: kernel.hung_task_timeout = 0 which is an invalid sysctl value it should say AFAICS kernel.hung_task_timeout_secs = 0 -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org

[opensuse-kernel] bnc #696474 and more weirdness
by Cristian Rodríguez 15 Jun '11

15 Jun '11

The following post is about the following bug that you must read to understand the rest... https://bugzilla.novell.com/show_bug.cgi?id=696474 After removing commit=100 from the mount options the symptoms mentioned in the bug report disappear, but still there is a mayor weirdness.. I call it, "everything is fine before midnight" Between 23:00 and 00:00 each day, cron jobs start rsync and various IO intensive processes, and it is when the apache server running in the same machine starts to segfault with random errors, sometimes there is not even a workable backtrace, memory gets corrupted somehow, It will keep segfaulting randomly even after rsync process has ended, the only solution is the reboot the box after those processes end. There is no kernel warning, error, I have run memtest86++ and memtester user-space utility, more than once, even for a complete night. The machine is not out of ram, it has at least 5 GB free and other 5GB cached. The only remotely related (????) warning I get is this: un 15 00:19:32 eq6 smartd[2555]: Device: /dev/twa0 [3ware_disk_00], SMART Prefailure Attribute: 1 Raw_Read_Error_Rate changed from 110 to 111 Jun 15 00:19:32 eq6 smartd[2555]: Device: /dev/twa0 [3ware_disk_00], SMART Usage Attribute: 195 Hardware_ECC_Recovered changed from 34 to 35 Googling says it is not something to worry about unless smart reports fail, neither the raid controller built-in error reporting nor smartd says nothing about broken disks. Everything is fine after reboot, until next midnight approaches..

[opensuse-kernel] kernel package versioning
by Michal Marek 14 Jun '11

14 Jun '11

Hi, Today I finally got round to properly fix the versioning mess in master and the upstream branches (vanilla and linux-next). This mail is meant to document how it's supposed to work. You can skip to the table at the end of the mail for a summary. In upstream ~~~~~~~~~~~ Upstream git tags look like "v3.0-rc1", "v3.0-rc2", the final tag is going to be "v3.0" and the subsequent stable releases will be tagged as "v3.0.1", "v3.0.2" and so on. The tarballs are named after these tags, so we have linux-3.0-rc2.tar.bz2 that contains the linux-3.0-rc2 directory. HOWEVER: Several userspace programs expect the kernel release string be three numbers and fail if it isn't the case. This also affects depmod, so omitting the third zero would break all setups using modules. So the kernel continues to call itself "3.0.0-rc2" and this will probably stay for some time now. In short, there are two version numbers now: I'll refer to them as the "tarball" version and the "uname" version (might differ from the "tarball" version in the trailing zero). In openSUSE ~~~~~~~~~~~ The SRCVERSION variable in the config.sh file is set to the "tarball" version. The mkspec script takes this and generates two more versions: The "uname" version (appends a zero if necessary), that is used during the build (so the actual build didn't require any modifications in the end) and the "rpm" version. I used the fact that the build was broken anyway as an opportunity to revamp the way the rpm packages are numbered. The final releases will have three numbers, i.e. "kernel-desktop-3.0.0-...", "kernel-desktop-3.0.1-...", etc. However, -rc releases will use the "rcX" tag instead of the last zero, so the current package will look like "kernel-desktop-3.0.rc2-...". Letters sort before numbers in rpm, so this will not break ordering and at the same time you will be able to tell the upstream version from the rpm version easily. Until now, we abused the rpm Release: field for this, but this only worked in the Kernel:* projects and not in the official distribution. To summarize, the mapping will be like: rpm tarball uname -r kernel-desktop-3.0.rc2-* linux-3.0-rc2.tar.bz2 3.0.0-rc2-*-desktop kernel-desktop-3.0.0-* linux-3.0.tar.bz2 3.0.0-*-desktop kernel-desktop-3.0.1-* linux-3.0.1.tar.bz2 3.0.1-*-desktop The "*" above is the rpm Release: number assigned by the build service. I hope that despite the long mail, the scheme will actually be easy to understand, that would will be able to quickly tell what kernel is in the distro by just looking at the rpm packages. Michal PS: I didn't cover KMPs at all at this point, they might work or there might be some fixes needed, I'll look into this later. -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-kernel+help(a)opensuse.org
