Bug#1032104: linux: ppc64el iouring corrupted read



Hi Otto,

Paul Gevers asked if the issues are gone as well with 6.1.12-1
(or later 6.1.y series versions, which will land in bookworm). That
would be valuable information to know as well to exclude we do not
have the issue as well in bookworm.

Were you able to verify this?

No, not yet.

I have not done new uploads to experimental after the one I mentioned
and linked above from March 18th.

I don't understand this point, so I wonder if you understood my question. Maybe you did, but in my view no new uploads are needed to answer the bookworm question.

The builds for unstable are passing because I forced the tests to run
with regular fsync instead of native I/O in
https://salsa.debian.org/mariadb-team/mariadb-server/-/commit/fc1358087b39ac6520420c7bbae2e536bc86748d.
I will test this again later but right now I don't want to do any
extra uploads as the package is pending unblock and inclusion in
Bullseye (Bug#1033811) and I don't want one single minor issue to
jeopardize getting fixes for multiple major issues forward.

My point was that I upgraded the ppc64el hosts where ci.debian.net runs the autopkgtests (so *not* the Debian build infrastructure). Since that upgrade, all tests on ci.debian.net *in every suite* have been using the bookworm (6.1.y) kernel.

E.g. in unstable MariaDb 1:10.11.2-1 (so before the "Prevent mariadb-test-run from using native I/O on ppc64el and s390x due to Linux kernel bug" change) passed on 2023-03-26 10:39 but failed on the same day at 14:40. Is any of the failures on ppc64el before 1:10.11.2-2 and after 2023-03-09 from the same kernel issue we're discussing here (and thus the kernel still needs fixing in bookworm). Or are all the failures in that time-span from something else, and thus can we conclude that the kernel *probably* (no proof of course) got fixed between the version of the kernel in bullseye and the version in bookworm.

Paul
