I found regression in the CentOS Stream 8 kernels, and create bug report https://bugzilla.redhat.com/show_bug.cgi?id=1913806
After reading https://wiki.centos.org/Contribute/CentOSStream I try to download kernel sources and look for root cause of bug, but dist-git and source-git repos does not contain kernel sources, even if I try to execute %prep phase. For this reason I can't even try to find root cause of this bug by myself.
This bug is critical for me, because currently I try to use systemd-nspawn for containers virtualization in production. If future CentOS 8.4 will contain this bug - it will be disaster.
What else I can do (as user or developer) for fixing this bug?
We should have a new kernel out in the next couple of days, next step would be to see if that bug is fixed in this build: https://koji.mbox.centos.org/koji/buildinfo?buildID=15499
I check latest CentOS Stream 8 kernel version 4.18.0-269.el8.x86_64 - this regression with broken nspawn containers still present here.
Does any chance exist that this kernel regression will be fixed in CentOS Stream 8 before CentOS 8.4 / RHEL 8.4 will be released?
One thing we might be able to update about the documentation if you're looking into the sources is to add a link here: https://wiki.centos.org/Sources (see the section there describing the get_sources.sh script). We store large sources in a separate lookaside, not directly in the dist-git trees.
Thank you! Now I can download source - but all patches are merged into one file linux-4.18.0-269.el8.tar.xz - I have no chances to find which patch to the kernel source tree causes this regression with broken systemd-nspawn containers. As I understand, only Red Hat kernel developers now can find the root cause of regression and fix it.
And all I can do is file a bug https://bugzilla.redhat.com/show_bug.cgi?id=1913806 and hope for the best?
