[opensuse-kernel] Reliability test for hard drives and SSD
by Andrey Ponomarenko 29 Jul '18

29 Jul '18

Hi there! Good news for all interested in hardware compatibility and reliability. I've started a new project to estimate reliability of hard drives and SSD in real-life conditions based on the SMART data reports collected by Linux users in the Linux-Hardware.org database since 2014. The initial data (SMART reports), analysis methods and results are publicly shared in a new github repository: https://github.com/linuxhw/SMART. Everyone can contribute to the report by uploading probes of their computers by the hw-probe tool! The primary aim of the project is to find drives with longest "power on hours" and minimal number of errors. The following formula is used to measure reliability: Power_On_Hours / (1 + Number_Of_Errors), i.e. time to the first error/between errors. Please be careful when reading the results table. Pay attention not only to the rating, but also to the number of checked model samples. If rating is low, then look at the number of power-on days and number of errors occurred. New drive models will appear at the end of the rating table and will move to the top in the case of long error-free operation. Thanks to ROSA, openSUSE, Gentoo, Ubuntu, Debian, Mint, Arch, Fedora users and others who had made this work possible by contribution to the database! -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org

[opensuse-kernel] After upgrading Kernel:/stable 4.12.x -> 4.13.x, boot reproducible fails to dracut emergency shell. "busname"?
by sigise＠mailc.net 03 Apr '18

Hi, After upgrading from Kernel:/stable 4.12.x -> 4.13.x, on Leap 42.3, the system no longer boots -- instead drops to dracut emergency shell. Unfortunately, at shell, I've got no keyboard, and I have no serial port, so having some challenges GRABBING the early logs to share. I turned on more verbose logging. At boot, although without keyboard I can't, unfortunately INTERRUPT it on screen, I DO see an ENORMOUS amount of output (moving by VERY quickly ...) re: "dracut-initqueue" and something about "settled" ... Rebooting to 4.12.x, and checking prior boot, in journalctl I do NOT see any mention of dracut, but I DO see journalctl -b -1 -- Logs begin at Mon 2016-11-07 13:36:46 PST, end at Tue 2018-03-27 10:17:20 PDT. -- Mar 27 09:37:01 0031.austin.local CRON[2126]: (CRON) ERROR chdir failed (/var/lib/amavisd): No such file or directory Mar 27 09:37:01 0031.austin.local systemd[2123]: pam_unix(systemd-user:session): session closed for user amavisd Mar 27 09:37:01 0031.austin.local systemd[2122]: user(a)5003.service: Executing: /usr/lib/systemd/systemd --user Mar 27 09:37:01 0031.austin.local systemd[2122]: systemd 228 running in user mode for user 5003/amavisd.

[opensuse-kernel] kernel tools packaging
by Guillaume Gardet 09 Mar '18

09 Mar '18

Hi, the kernel provides a number of tools in the tools/ subdir. I think some of them would be nice to package, such as tools/gpio and tools/spi, especially for ARM. What would be the best way to do it? Integrate those tools in kernel packaging (Create a new spec file in kernel sources), or create a standalone package outside the kernel packaging (see [1])?

[opensuse-kernel] [PATCH] x86/kvm/vmx: do not use vm-exit instruction length for fast MMIO when running nested
by Matwey V. Kornilov 06 Mar '18

06 Mar '18

From: Vitaly Kuznetsov <vkuznets(a)redhat.com> I was investigating an issue with seabios >= 1.10 which stopped working for nested KVM on Hyper-V. The problem appears to be in handle_ept_violation() function: when we do fast mmio we need to skip the instruction so we do kvm_skip_emulated_instruction(). This, however, depends on VM_EXIT_INSTRUCTION_LEN field being set correctly in VMCS. However, this is not the case. Intel's manual doesn't mandate VM_EXIT_INSTRUCTION_LEN to be set when EPT MISCONFIG occurs. While on real hardware it was observed to be set, some hypervisors follow the spec and don't set it; we end up advancing IP with some random value. I checked with Microsoft and they confirmed they don't fill VM_EXIT_INSTRUCTION_LEN on EPT MISCONFIG. Fix the issue by doing instruction skip through emulator when running nested.

[opensuse-kernel] openSUSE Tumbleweed will receive signed modules
by Jiri Slaby 02 Mar '18

02 Mar '18

Hi, we currently sign the kernel in openSUSE but we don't sign modules. I am not going to open the questions for released/semi-released products like openSUSE 42.3 or openSUSE 15. But I see no reason why we shouldn't sign modules in Tumbleweed and in releases forked from TW in the future. The reasons are at least: * to allow for more security (attackers have harder times to replace our modules with theirs) * offer what SLE offers. We have modules signing there since SLE11 (i.e. 2012)! * be competitive with other distros; ubuntu and fedora both sign So my plan is to enable modules signing in the near future, perhaps even before merging 4.16 and push it out to the wild. There may be some nits to solve, but given we are flying on SLE for years already, it should be no hard work. As the next step, I would love to have kernels in Kernel:* signed by SUSE keys too. The current state forces people who test them (me including) to have secure boot disabled. That is not nice at all. thanks, -- js suse labs -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-kernel+owner(a)opensuse.org
