[Bug 2089318] Re: kernel hard lockup in cgroups during eBPF workload

2025-06-03 Thread Ubuntu Kernel Bot
This bug is awaiting verification that the linux-nvidia-
tegra-5.15/5.15.0-1039.39~20.04.1 kernel in -proposed solves the
problem. Please test the kernel and update this bug with the results. If
the problem is solved, change the tag 'verification-needed-focal-linux-
nvidia-tegra-5.15' to 'verification-done-focal-linux-nvidia-tegra-5.15'.
If the problem still exists, change the tag 'verification-needed-focal-
linux-nvidia-tegra-5.15' to 'verification-failed-focal-linux-nvidia-
tegra-5.15'.


If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.


See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

If you search the changelog at: https://git.launchpad.net/~ubuntu-
kernel/ubuntu/+source/linux/+git/jammy/tree/debian.master/changelog?h=master-
next

for:
 2089318

it has this block of text:
  * kernel hard lockup in cgroups during eBPF workload (LP: #2089318)
- cgroup: cgroup: Honor caller's cgroup NS when resolving cgroup id
- cgroup: Homogenize cgroup_get_from_id() return value
- cgroup: Make cgroup_get_from_id() prettier
- cgroup.c: add helper __cset_cgroup_from_root to cleanup duplicated codes
- cgroup: Reorganize css_set_lock and kernfs path processing


Which are the commits for this change.

If we check the tag for there kernel version Ubuntu-5.15.0-140.150 we
can see which SRU cycle it will be part of:

[Bug 2089318] Re: kernel hard lockup in cgroups during eBPF workload

2025-04-28 Thread Sylvie Guo
Hi Philip,

We are right now about to release a image based upon linux-image-aws-
lts-22.04, which depends on linux-image-5.15.0-1082-aws(built upon
linux-aws (= 5.15.0-1082.89)). We checked the source for the unsigned
image package(linux-image-unsigned-5.15.0-1082-aws). The fix in
https://lists.ubuntu.com/archives/kernel-team/2025-January/156161.html
doesn't seem to be there

Wonder if the fix is released to Ubuntu mainline kernel, thank you very
much for following up on this to this point.

Hi Max, sorry about the late response.  The patch got NACK'ed in review
and that only happened on the last day for patch submissions so I was
unable to make it into the cycle.  I am targeting it to the next cycle,
2025.02.10.

From: https://kernel.ubuntu.com/

The 2025.02.10 SRU cycle has a targetted release date the week of 10
March 2025.
