The upstream time64 work removed vDSO acceleration from these functions. We should restore it. Note that it is unclear whether upstream will accept this patch.
Upstream patch proposal: Patch posted: https://sourceware.org/pipermail/libc-alpha/2021-July/128902.html Let me stress again that upstream acceptance is unclear at this point.
A different patch was accepted upstream, which I believe is equivalent. I believe the second issue (errno clobber) can be validated using a scratch build of dovecot. This is also covered by new test cases in the upstream glibc test suite.
Any ETA when this will be in build root? It blocks dovecot's builds
(In reply to Michal Hlavinka from comment #4) > Any ETA when this will be in build root? It blocks dovecot's builds glibc-2.33.9000-42.el9 has been tagged, so it will land in the buildroots in a few minutes.
