[opensuse-kernel] Keep 3.11.y kernel for openSUSE 13.1 updates?
by Takashi Iwai 12 Sep '14

12 Sep '14

Hi, Since 3.11.y maintenance was discontinued by Greg, Ubuntu took over it. It made me wonder: are we willing to continue 3.11.y for openSUSE 13.1 updates, just relying on Ubuntu? Or, can we just move on 3.12.y? Takashi -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

[opensuse-kernel] Modular drivers which could be built-in
by Jean Delvare 10 Mar '14

10 Mar '14

Hi all, Having worked on built-in drivers which could be modularized, I am now looking for modular drivers which could be built-in. Our policy is that drivers which are not hardware-specific and are needed on a majority of systems should be built into the kernel directly. So I checked which modules were loaded on my 4 systems. After filtering out hardware-specific modules, I am left with the following list: ACPI and thermal drivers: * button * processor * thermal_sys Block device drivers * cdrom * scsi_dh * scsi_dh_alua * scsi_dh_emc * scsi_dh_hp_sw * scsi_dh_rdac * sg * sr_mod Graphics helper drivers * drm * drm_kms_helper * i2c_algo_bit Filesystem drivers: * fuse * lockd * sunrpc CPU drivers: * microcode Sound drivers: * pcspkr * snd * snd_page_alloc * snd_pcm * snd_seq * snd_seq_device * snd_timer * soundcore If anyone has an opinion on whether these should be built into the kernel or left as modules, this is the right time to discuss it. My personal thoughts, with mostly x86 in mind: * The ACPI button and processor drivers could be built-in. Most x86 systems use ACPI and they supposedly all have at least one processor and one power button ;) And thermal_sys is selected by processor. * While all my systems have an optical drive, I know they have disappeared from many systems, both very small and very large ones, so leaving cdrom and sr_mod as modules seems fine. * I have no idea why/how sg is being loaded, it has no modalias and no other module depend on it. But /dev/sd* nodes are created so it is certainly useful. Hannes? * No idea what the scsi_dh* modules are about either, no modalias and no dependencies either. Hannes? * With DRM/KMS being the norm now, I believe drm and drm_kms_helper could be built-in, even though the former is quite large. drm selects i2c-algo-bit, most (all?) DRM/KMS drivers use it. Even servers have graphics chips. * I suppose fuse is only used on desktop machines by default, for gvfs, so having it as a module seems OK. * lockd and sunrpc are dependencies of nfs and nfsd. I suppose there are many users out there who don't serve nor mount NFS shares so modules make sense. * I think microcode could be unloaded after use, maybe for security reasons it might even be preferable, or just because there is simply no point in keeping it in memory. Thomas? Either way we should keep it modular. * For sound drivers, Takashi should know better than me. I suppose that the rationale for having these modular is that servers have no sound chip? -- Jean Delvare Suse L3 -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

[opensuse-kernel] Is there a solution for the CVE-2014-0038 around?
by Stefan Hoese 07 Mar '14

07 Mar '14

Hello, did I miss something or is this [1][2] still unpatched in openSUSE 12.3 and 13.1 kernels? After: zypper in linux-sources and: grep -r -e "if (get_compat_timespec(&ktspec, timeout))" /usr/src/* there was the expected output for the _unpatched_ kernel. Much worse, the "CONFIG_X86_X32=y" (for openSUSE 13.1) and "CONFIG_X86_32=y" (for openSUSE 12.3) seems to be available in *every* kernel configuration. Is there a chance to use any kernel parameters for deactivating this problem? I didn't find any solution. Manually patching the kernel is no option for me. In the case of patching myself and the assumption that it will not be fixed in the repositories I will probably end up repairing this after every kernel update. Kind regards, Stefan References: [1] http://www.openwall.com/lists/oss-security/2014/01/31/2 [2] https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=… -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

[opensuse-kernel] user/sys ticks for process exceed overall user/sys ticks
by Peter Hofer 06 Mar '14

06 Mar '14

Hello everyone! (I recently posted about this on linux-kernel, but got no responses. I would be very grateful for any pointers.) I am trying to determine what fraction of the whole system's user and sys time are consumed by a specific process, over a period of time. Hence, I read the respective tick counts from the first lines of /proc/stat and /proc/<pid>/stat at the start and end of that period and compute deltas. However, on an otherwise idle system, I often see the ticks consumed by a threaded process exceed those of the whole system. The difference is not just a few ticks, but can amount to over 10%, regardless of how long the observed time period is. There is no virtualization involved. I have been able to reproduce this with the current openSUSE and Ubuntu releases on different x86_64 machines. How can this be explained? Intuitively, I would expect that a tick accounted to a running task is at the same time accounted to the CPU it is running on, and so a process can never be accounted more ticks than the whole system, i.e. all CPUs. I have attached a simple Python script to reproduce this behavior. Example output: > ./ticks.py delta process: user: 2495 sys: 181 delta all: user: 2283 sys: 258 Thanks, Peter

[opensuse-kernel] mkinitrd problem after kernel upgrade
by Giacomo Comes 11 Feb '14

11 Feb '14

Hi, the problem I'm reporting can be observed only if the line multiversion = provides:multiversion(kernel) in /etc/zypp/zypp.conf is commented. That is what I do normally because I only want the latest kernel installed. This does not cause any problem in 12.3 but in 13.1 it does. After running "zypper update" which have updated the kernel to 3.11.10-7.1 when i run mkinitrd I get this output: Kernel image: /boot/vmlinuz-3.11.10-7-default Initrd image: /boot/initrd-3.11.10-7-default KMS drivers: cirrus Root device: /dev/disk/by-uuid/319415ea-d50e-4216-8f96-4aa8fc7b515e (/dev/sda2) (mounted on / as ext4) Resume device: /dev/disk/by-uuid/16e9fbd6-30b9-4207-b0da-a989c6982c89 (/dev/sda1) Kernel Modules: thermal_sys thermal processor fan scsi_dh scsi_dh_emc scsi_dh_alua scsi_dh_hp_sw scsi_dh_rdac syscopyarea sysfillrect sysimgblt drm drm_kms_helper ttm cirrus ata_piix usb-common usbcore ohci-hcd uhci-hcd ehci-hcd xhci-hcd usbhid hid-logitech-dj hid-generic hid-holtek-kbd hid-lenovo-tpkbd hid-ortek hid-roccat hid-roccat-common hid-roccat-arvo hid-roccat-isku hid-samsung ehci-pci ohci-pci libcrc32c xor zlib_deflate raid6_pq btrfs crc32c-intel Features: acpi kms plymouth block usb btrfs resume.userspace resume.kernel Kernel image: /boot/vmlinuz-3.11.10-7-desktop Initrd image: /boot/initrd-3.11.10-7-desktop KMS drivers: cirrus Root device: /dev/disk/by-uuid/319415ea-d50e-4216-8f96-4aa8fc7b515e (/dev/sda2) (mounted on / as ext4) Resume device: /dev/disk/by-uuid/16e9fbd6-30b9-4207-b0da-a989c6982c89 (/dev/sda1) Kernel Modules: thermal_sys thermal processor fan scsi_dh scsi_dh_emc scsi_dh_alua scsi_dh_hp_sw scsi_dh_rdac syscopyarea sysfillrect sysimgblt drm drm_kms_helper ttm cirrus ata_piix xhci-hcd hid-logitech-dj hid-holtek-kbd hid-lenovo-tpkbd hid-ortek hid-roccat hid-roccat-common hid-roccat-arvo hid-roccat-isku hid-samsung ohci-pci libcrc32c xor zlib_deflate raid6_pq btrfs crc32c-intel Features: acpi kms plymouth block usb btrfs resume.userspace resume.kernel Kernel image: /boot/vmlinuz-3.11.6-4-default Initrd image: /boot/initrd-3.11.6-4-default Root device: /dev/disk/by-uuid/319415ea-d50e-4216-8f96-4aa8fc7b515e (/dev/sda2) (mounted on / as ext4) Resume device: /dev/disk/by-uuid/16e9fbd6-30b9-4207-b0da-a989c6982c89 (/dev/sda1) modprobe: Module thermal not found.

The reason for them being installed is that some kernel module rpms (ndiswrapper-kmp, vhba-kmp, virtualbox-guest-kmp, virtualbox-host-kmp) in the 13.1 repository explicitely requires the presence of kernel 3.11.6-4. If i run: rpm -q --requires vhba-kmp-default it shows the line: kernel-uname-r = 3.11.6-4-default Such strict requirement of a kernel version is not present in the vhba-kmp rpm of 12.3. Is this new strict requirement something that was decided or it is the result of a bug? Is there a fix for my problem or I cannot have anymore only one kernel installed?
