[Kernel-packages] [Bug 1835939] Re: The 18.04 linux kernel hangs and crashes when shutting down a Windows 10 instance running under vmware
Thanks Scott, I've made the bug public. There's a surprising number of crashes reported to the error tracker -- I wonder if your hardware is entirely stable? Have you run memtest86 or memtest86+ recently? Is there anything in your smartctl output that would indicate drive problems?

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy.

Re: [Kernel-packages] [Bug 1861359] Re: swap storms kills interactive use

Could you try to set that > to 0 (kernel prefers to drop file-backed pages instead of swapping out > anonymous pages) and see if the swap out activity is still happening? Unfortunately, this did not solve the problem. Setting swappiness to 0 and re-enabling my swap nearly immediately caused the whole computer to lag whenever firefox had focus -- and swap use jumped to 380M, despite having roughly five gigs free space. Turning swap back off again helped immensely.

Title:
[Bionic] i915 incomplete fix for CVE-2019-14615
Status in linux package in Ubuntu:
Invalid
Status in linux source package in Bionic:
In Progress
Bug description:
[Impact]
Gregory Herrero reported that the proof-of-concept for CVE-2019-14615
indicates that the information leak is not fixed in the Bionic 4.15
kernel as indicated by USN-4255-1:
https://usn.ubuntu.com/4255-1/
This only affects Ubuntu's 4.15 kernel series. Xenial (4.4), Disco
(5.0), Eoan (5.3), and Focal (5.4) are not affected by this incomplete
fix issue.
I've verified this by testing each Ubuntu release with the proof-of-
concept. I then tested vanilla 4.15 with commit bc8a76a152c5
("drm/i915/gen9: Clear residual context state on context switch")
applied, which is the fix for CVE-2019-14615, and verified that the
proof-of-concept showed that the info leak was still possible. I then
tested vanilla 4.16 with commit bc8a76a152c5 applied to verify that
the proof-of-concept showed that the info leak was fixed.
After bisecting changes to the DRM subsystem as well as the i915
driver, it looks like commit d2b4b97933f5 ("drm/i915: Record the
default hw state after reset upon load") as well as its prerequisites
are necessary to fully fix CVE-2019-14615 in 4.15 based kernels.
[Test Case]
A proof-of-concept for CVE-2019-14615 became available once the issue
was made public. It can be found here:
https://github.com/HE-Wenjian/iGPU-Leak
Steps to use the proof-of-concept:
$ git clone https://github.com/HE-Wenjian/iGPU-Leak.git
# In one terminal
$ cd iGPU-Leak/demo/SLM_Leak/
$ ./run_victim.sh
# In another terminal
$ cd iGPU-Leak/demo/SLM_Leak/
$ ./run_attacker.sh
# In the terminal running run_attacker.sh, ensure that all data dumped
# to the terminal is zeros and that there is no non-zero data. You'll
# have to closely monitor the script for a minute or so to ensure that
# the information leak is not possible.

[Kernel-packages] [Bug 1814983] Re: zfs poor sustained read performance from ssd pool
Thanks Colin,
I believe that bountysource.com url is a scrape of
https://github.com/openzfs/zfs/issues/6223
I hadn't seen much of this information before.
Sadly my machine doesn't have enough memory to just keep turning up the
knobs -- the working set far exceeds the memory of my computer.
A recent archive-wide search I performed, I tried the following:
echo 126491074560 >> /sys/module/zfs/parameters/zfs_arc_max # eight gigs less
than RAM
echo 117901139968 >> /sys/module/zfs/parameters/zfs_arc_dnode_limit # eight
gigs less than ^^
I picked these numbers entirely at a guess. The zfs arc had previously
been 0 -- for half of ram, 64 gigabytes.
This workload seemed to run fine for longer than usual (arc_prune cpu
numbers were low, good read iops reported in zpool status output -- not
ideal indicator of actual progress, but a reasonable proxy) but
eventually the arc_prune tasks started consuming most of the CPUs, and
read iops fell to the dozens.
I haven't tried a run with silly low numbers for the arc dnode limit,
but I'm curious...
Thanks

Hello,
I'm seeing substantially slower read performance from an ssd pool than
I expected.
I have two pools on this computer; one ('fst') is four sata ssds, the
other ('srv') is nine spinning metal drives.
With a long-running ripgrep process on the fst pool, performance
started out really good and grew to astonishingly good (iirc ~30kiops,
as measured by zpool iostat -v 1). However after a few hours the
performance has dropped to 30-40 iops. top reports an arc_reclaim and
many arc_prune processes to be consuming most of the CPU time.
I've included a screenshot of top, some output from zpool iostat -v 1,
and arc_summary, with "===" to indicate the start of the next

[Kernel-packages] [Bug 1814983] Re: zfs poor sustained read performance from ssd pool
Writing 8589934592 (eight gigs) into the zfs_arc_dnode_limit seemed to
make an improvement: the arc_prune threads would periodically spike
above 20% CPU use, but would return to 2-5% CPU use quickly; it worked
well for a long time, perhaps even hours, before all the arc_prune
threads returned to ~50% CPU use.
I tried one gigabyte for a bit but the arc_prune threads returned
quickly. Tuning this may take a bit.
Thanks for the tip.

Andrea, I've been running the v1 kernel for a day or so now: [0.00] Linux version 5.4.0-24-generic (arighi@sita) (gcc version 9.3.0 (Ubuntu 9.3.0-10ubuntu1)) #28+lp1861359v1 SMP Wed Apr 15 14:49:33 UTC 2020 (Ubuntu 5.4.0-24.28+lp1861359v1-generic 5.4.30) $ uptime 02:21:45 up 1 day, 9 min, 14 users, load average: 0.42, 0.25, 0.23 and have not seen any hangs or stalls of any sort in the ~ten hours that I've been using it. Normally these problems start to appear about a day into use, so it's perhaps still early to declare success, but this is looking promising. Even loading https://platform.leolabs.space/visualization in firefox just causes momentary glitches in mouse movement, like 50ms kind of range. (I know this range is pretty poor for humans to tell, but it sure feels like less than half a second by a lot.)

[Kernel-packages] [Bug 1814983] Re: zfs poor sustained read performance from ssd pool
Andreas, this system is running 18.04 LTS, 0.7.5-1ubuntu16.8,
4.15.0-91-generic.
It has 128 gigs of ram; the workload is running ripgrep on an entire
unpacked Ubuntu source archive, roughly 193 million files, 3.8 TB of
data, on a single raidz1 ssd vdev.
So I have no illusions that this workload fits into the available
memory, but it's unfortunate that the best performance I've found so far
includes dropping caches every few minutes.
Thanks

Title:
zfs poor sustained read performance from ssd pool
Status in Native ZFS for Linux:
Unknown
Status in zfs-linux package in Ubuntu:
Incomplete
Bug description:
Hello,
I'm seeing substantially slower read performance from an ssd pool than
I expected.
I have two pools on this computer; one ('fst') is four sata ssds, the
other ('srv') is nine spinning metal drives.
With a long-running ripgrep process on the fst pool, performance
started out really good and grew to astonishingly good (iirc ~30kiops,
as measured by zpool iostat -v 1). However after a few hours the
performance has dropped to 30-40 iops. top reports an arc_reclaim and
many arc_prune processes to be consuming most of the CPU time.
I've included a screenshot of top, some output from zpool iostat -v 1,
and arc_summary, with "===" to indicate the start of the next
command's output:

[Kernel-packages] [Bug 1814983] Re: zfs poor sustained read performance from ssd pool
Hello Colin, this looks promising for my arc_prune spinlock contention
problems:
https://github.com/openzfs/zfs/pull/10331
with some background here:
https://github.com/openzfs/zfs/issues/7559
This might have a simple ~dozen line fix! It's not yet reviewed by the
openzfs gurus but it sure *looks* plausible to me. I tried to bodge this
patch into the dkms module you gave me for my other zfs problem, but I
have no confidence in my work -- I tried to reduce the number of
arc_prune threads but failed, so I'm skeptical if I was able to change
anything anyway. (I'm finding dkms to be *very* confusing.)
Any chance I can ask you to put together a dkms with this patch? I'd
trust your work way further. :)
Thanks

zfs poor sustained read performance from ssd pool
Status in Native ZFS for Linux:

Bug description:
Hello,
I'm seeing substantially slower read performance from an ssd pool than
I expected.
I have two pools on this computer; one ('fst') is four sata ssds, the
other ('srv') is nine spinning metal drives.
With a long-running ripgrep process on the fst pool, performance
started out really good and grew to astonishingly good (iirc ~30kiops,
as measured by zpool iostat -v 1). However after a few hours the
performance has dropped to 30-40 iops. top reports an arc_reclaim and
many arc_prune processes to be consuming most of the CPU time.
I've included a screenshot of top, some output from zpool iostat -v 1,
and arc_summary, with "===" to indicate the start of the next
command's output:

[Kernel-packages] [Bug 1310717] Re: process segfaults, hung task timeouts
I'm sorry, I can't recall that system very well at this point. "gmain" is the generic name used by any application using glib's g_get_worker_context() function to create worker threads. At this point I can't even recall if I booted that system with X11 / lightdm or if I had configured it to boot to multiuser only. About the only thing I used that system for was tmux and irssi, neither of which are using the thread name 'gmain' in Xenial, so they were probably also not using the name in Saucy. So, it would have been supplied by 'standard' system software, not something I chose to run myself. My pandaboard es killed SD cards pretty quickly, I came away with the impression that SD cards are basically garbage not intended for 'real' system use: segfaults and bus faults were the common symptom, and this may have been a symptom of rubbish SD card too.

I'm adding the champagne tag to this bug to bring it to a potential wider audience; I think we may need to take more drastic steps like disabling swap on upgrades, not offering swap in our installers, etc., to try to have a better experience.

[Kernel-packages] [Bug 1861359] Re: swap storms kills interactive use
Sultan, thanks for the advice. I set this watermark boost factor to zero as you suggested, and then decided to try a stupid simple benchmark of my storage -- my swap is a zfs dataset on nvme. zfs means it'll go slower than raw nvme block access: $ dd if=ubuntu-18.04.4-desktop-amd64.iso of=foo bs=$((1024*1024)) conv=fsync 2028+1 records in 2028+1 records out 2126544896 bytes (2.1 GB, 2.0 GiB) copied, 6.91399 s, 308 MB/s And this is a sequential workload with large blocks rather than random with pages, but it gives the flavour of the speed well enough. Anyway, my system hung again when re-focusing firefox even after changing the watermark boost factor to zero. It was unusable for ten or twenty seconds. I have loads of free memory, it shouldn't be in swap: $ free -h totalusedfree shared buff/cache available Mem: 15Gi11Gi 1.6Gi 643Mi 2.2Gi 2.8Gi Swap: 2.0Gi23Mi 2.0Gi Thanks -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1861359 Title: swap storms kills interactive use Status in linux package in Ubuntu: Confirmed Bug description: [Impact] High watermark boosting can cause large swap activity under certain memory intensive workloads, making the system very unresponsive (screen does not refresh, keyboard not responding, etc.).

tracing doesn't work on focal

Bug description:
Hello, while investigating bug 1861359 I tried to use kprobe-perf to
troubleshoot and found that tracing doesn't work on focal:
# kprobe-perf -s 'p:shrink_node'
ERROR: func shrink_node not in
/sys/kernel/debug/tracing/available_filter_functions.
Either it doesn't exist, or, it might be unsafe to kprobe. Exiting. Use -F to
override.

[Kernel-packages] [Bug 1779736] Re: umask ignored on NFSv4.2 mounts
The default NFSv4 acls may be a poor choice on ZOL. This keeps biting people unexpectedly, I wonder how many people this has affected and they never spot it? Thanks ** Also affects: zfs-linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1779736 Title: umask ignored on NFSv4.2 mounts Status in linux package in Ubuntu: Confirmed Status in nfs-utils package in Ubuntu: Confirmed Status in zfs-linux package in Ubuntu: New Bug description: After upgrading to kernel 4.15.0-24-generic (on Ubuntu 18.04 LTS) NFSv4.2 mounts ignore the umask when creating files and directories. Files get permissions 666 and directories get 777. Therefore, a umask of 000 is seemingly being forced when creating files/directories in NFS mounts. Mounting with noacl does not resolve the issue. How to replicate: 1. Mount an NFS share (defaults to NFSv4.2) 2. Ensure restrictive umask: umask 022 3. Create directory: mkdir test_dir 4. Create file: touch test_file 5. List: ls -l The result will be: drwxrwxrwx 2 user user 2 Jul 2 12:16 test_dir -rw-rw-rw- 1 user user 0 Jul 2 12:16 test_file while the expected result would be drwxr-xr-x 2 user user 2 Jul 2 12:16 test_dir -rw-r--r-- 1 user user 0 Jul 2 12:16 test_file Bug does not occur when mounting with any of: vers=3 vers=4.0 vers=4.1 I have a suspicion this is related to: https://tools.ietf.org/id/draft-ietf-nfsv4-umask-03.html But since the server does not have ACL's enabled, and mounting with noacl does not resolve the issue this is unexpected behavior.

I couldn't find a way to disable the lockdown functionality short of disabling secure boot in my UEFI system setup.

[Kernel-packages] [Bug 1861359] Re: swap storms kills interactive use
There is an interesting (to me, anyway) change of behaviour with the -17 kernel: while earlier kernels would appear to be locked solid for 30-60 seconds before the screen could update, -17 allows screen updates every six seconds or so. I have an always-running mosh session to a remote host running irssi. This session has a clock that updates every second. When this problem strikes I can glance at this clock and by watching the time jumps, gauge how long the hangs are. When the -17 kernel hangs during these events, this clock updates roughly every six seconds: eg on seconds 36, 42, 48, 54, 00, 06, 13, 19, 25, 31, 37, 43, 50, 56.. The system is by no means usable during this time, but it is interesting that enough userspace ran for mosh to accept packets and redraw the urxvt terminal, and xorg to update the screen. My most recent hang happened while firefox loaded https://www.google.com/maps/place/20%C2%B054'35.7%22S+55%C2%B035'05.0%22E/@-20.9099167,55.5826253,2281m/data=!3m2!1e3!4b1!4m5!3m4!1s0x0:0x0!8m2!3d-20.90991!4d55.58471 but it might be the case that this is just what pushed my browser over the edge, after loading several pages of google docs content and a PDF.

I installed Ubuntu Server 16.04.2 (latest ISO I had on hand), installed fine. I then ran apt-get update, apt-get upgrade... upgrade failed as repos were out of date. I then ran do-distribution-upgrade, ran through everything and it appears to work. --I don't want to mislead anyone - I can't remember if I rebooted or not at this point. After this, I setup an Iscsi initiator to an external target, added to fstab, formatted and confirmed all working. I then rebooted, and... nothing! No ping, no ssh or anything... Control + Alt + Del did not work, looked like it had frozen. The last line was starting SSH, but the previous line was the Iscsi initiator. At this point, I figured network is down and ISCSI is hanging as it can't connect/maybe I messed up the ISCSI mount. I then went to GRUB and did advanced, I did the recovery console for kernel 4.15.0-72 generic which lead to a kernel panic: https://snipboard.io/YCOZwv.jpg I then went through the options again and selected 4.4.0-62 generic, and it booted fine, and after about 2 seconds at the recovery menu, further ISCSI related text came up: https://snipboard.io/ALZcsF.jpg I went to the shell as root, deleted the line from fstab, and rebooted, but, it hang again at the same point. I then went to advanced, booted normally to 4.4.0-62 generic, and, it went through without any issue what so ever. Messing around with kernels puts me out of my depth... happy to give further info or do more diagnostics if required, however, due to it working in a different kernel and nothing out of the ordinary - I believe this to be a bug.

[Kernel-packages] [Bug 1860822] Re: ptrace fails with yama/ptrace_scope=0
Hello, this appears to be working as designed. In Linux, process tracing is tied with the process dumping flag. The dumpable flag is cleared at execve(2) time when a setuid or setgid application is executed. This flag persists to child processes created by fork(2) and will only be reset when a process calls execve(2) again. The server.c program does not call any of the exec() family of functions, nor system(3). Thus the flag is never set in the child process. You may be able to amend your application to call prctl(2) with PR_SET_DUMPABLE if you wish to be able to trace the child. I will caution you that the child may contain private data from the parent in either shared memory segments that are open in both, copied memory segments, duplicated file descriptors, etc. It would be better to change your application design to use an execve(2) when starting a child process that must be traced to ensure that a minimum of resources are shared between parent and child. Many thanks for the very clear description and source code. It really helped me to understand what you were seeing and why.

No mouse movement, no keyboard input, the screen output does not change. My computer was using swap space and despite very slow writeout speeds well below what the NVME drive can handle, the computer was unusable. I've captured some vmstat 1 output and top output that I started collecting during the event. (Normally one very long painful period is followed by several shorter periods of uselessness.)
