[M] Change in libosmocore[master]: Automatically increase io_uring, if too small.

by pespin

Attention is currently required from: jolly, laforge. pespin has posted comments on this change by jolly. ( https://gerrit.osmocom.org/c/libosmocore/+/40725?usp=email ) Change subject: Automatically increase io_uring, if too small. ...................................................................... Patch Set 3: (1 comment) Patchset: PS2: > this was based on a discussion aeversberg and I had before he started to wrok on the patch. […] I foresee lots of weird stuff happening only in those "super-rare events" we may not think about or which may end up with undefined behavior, eg. with one socket ending up with sqes in 2 different rings. IMHO we should explore the possibility of, in case io_uring_get_sqe() fails, append the osmo_iofd to some sort of "wait_read_sqe_queue" which is re-attempted every time a completed() event happen on the queue. This sounds like a lot less trouble now and in the future. -- To view, visit https://gerrit.osmocom.org/c/libosmocore/+/40725?usp=email To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings?usp=email Gerrit-MessageType: comment Gerrit-Project: libosmocore Gerrit-Branch: master Gerrit-Change-Id: Id9230146acc8d54bfd44834e783c31b37bd64bca Gerrit-Change-Number: 40725 Gerrit-PatchSet: 3 Gerrit-Owner: jolly <andreas(a)eversberg.eu> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: laforge <laforge(a)osmocom.org> Gerrit-CC: pespin <pespin(a)sysmocom.de> Gerrit-Attention: jolly <andreas(a)eversberg.eu> Gerrit-Attention: laforge <laforge(a)osmocom.org> Gerrit-Comment-Date: Wed, 23 Jul 2025 14:39:50 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: laforge <laforge(a)osmocom.org> Comment-In-Reply-To: pespin <pespin(a)sysmocom.de>

Otherwise we may end up submitting half-filled msghdr->{msg,iov}[] as a consequence of this code path.
