I don't get it. The latest ZFS version in Jammy seem to be 2.1.5 and not 2.1.14 nor 2.2.2. When will the committed version with the fix be available to the general public?

Some of them, at varying real-life reproducibility frequency have been deterimed to affect very old zfs releases. Recommendation is to upgrade to 2.2.2 or 2.1.14 or backport dnat patch alone. This is to ensure users get other potentially related fixes and runtime tunables to possibly mitigate other bugs that are related and are being fixed upstream for future releases. * For jammy the 2.1.14 upgrade will bring HWE kernel support and also compatiblity/support for hardened kernel builds that mitigate SLS (straight-line-speculation). * In the absence of the upgrade a cherry-pick will address this particular popular issue alone - without addressing other issues w.r.t. Redbleed / SLS, bugfixes around trim support, and other related improvements that were discovered and fixed around the same time as this popular issue. [ Test Plan ] * !!! Danger !!! use reproducer from https://zfsonlinux.topicbox.com/groups/zfs-discuss/T12876116b8607cdb and confirm if that issue is resolved or not. Do not run on production ZFS pools / systems. * autopkgtest pass (from https://ubuntu-archive- team.ubuntu.com/proposed-migration/ ) * adt-matrix pass (from https://kernel.ubuntu.com/adt-matrix/ ) * kernel regression zfs testsuite pass (from Kernel team RT test results summary, private) * zsys integration test pass (upgrade of zsys installed systems for all releases) * zsys install test pass (for daily images of LTS releases only that have such installer support, as per iso tracker test case) * LXD (ping LXD team to upgrade vendored in tooling to 2.2.2 and 2.1.14, and test LXD on these updated kernels) [ Where problems could occur ] * Upgrade to 2.1.14 on jammy with SLS mitigations compatiblity will introduce slight slow down on amd64 (for hw accelerated assembly code- paths only in the encryption primitives) * Uncertain of the perfomance impact of the extra checks in dnat patch fix itself. Possibly affecting speed of operation, at the benefit of correctness. * The cherry-picked patch ("dnat"? dnode) changes the dirty data check, but only makes it stronger and not weaker, thus if it were incorrect, likely only performance would be impacted (and it is unlikely to be incorrect given upstream reviews and attention to data corruption issues; also, there are no additional changes to that function upstream) [ Other Info ] * https://github.com/openzfs/zfs/pull/15571 is most current consideration of affairs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zfs-linux/+bug/2044657/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
