fixeria has uploaded this change for review. ( https://gerrit.osmocom.org/c/libosmocore/+/41685?usp=email ) Change subject: logging: change gsmtap target to use wqueue by default ...................................................................... logging: change gsmtap target to use wqueue by default In b72867f0 ("logging: Change stderr + file target to use non-blocking write") the `stderr` and `file` targets were changed to use the write queue in order to avoid blocking. Do the same for the `gsmtap` logging target, which can also be blocking under some circumstances.

[S] Change in libosmocore[master]: io_uring: RECVMSG_SENDMSG: Reset fd to blocking after osmo_fd_registe...
by pespin 16 Dec '25

16 Dec '25

Attention is currently required from: daniel, fixeria, jolly, laforge, osmith. Hello Jenkins Builder, daniel, fixeria, jolly, laforge, osmith, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/libosmocore/+/41671?usp=email to look at the new patch set (#4). The following approvals got outdated and were removed: Verified+1 by Jenkins Builder Change subject: io_uring: RECVMSG_SENDMSG: Reset fd to blocking after osmo_fd_register() workaround ...................................................................... io_uring: RECVMSG_SENDMSG: Reset fd to blocking after osmo_fd_register() workaround When IOFD_FLAG_NOTIFY_CONNECTED is requested by the user through osmo_iofd_notify_connected(), a write_cb(0, NULL) callback is done towards the user to notify the socket is connected. In mode RECVMSG_SENDMSG, at least for SCTP sockets, according to comment in iofd_uring_register() (see also OS#5751) we cannot do the write(0) trick to get notifications, so instead we need to workaround by using a temporary osmo_fd to poll() for write status. To do so, we call osmo_fd_register(), which internally sets the fd as non-blocking (O_NONBLOCK). However, this is becomes an undesired behavior later on when connect happens and io_uring is used to recvmsg/sendmsg, since that could cause sqes to be answered with -EAGAIN cqes at the kernel isntead of keeping (blocking) them internally until the transaction can be resolved. This seems was a "desired" or "expected" behavior in older kernels according to public discussions/tickets, but it seeems it changed over time (see eg. GH#364 below). In summary, the conclusion seems to be: try to avoid as much as possible mixing O_NONBLOCK with io_uring, as you may get totally unexpected/changing behavior. Hence, avoid keeping O_NONBLOCK for those sockets when moving back from osmo_fd to io_uring. See regarding related discussion on the expected behavior with io_uring and O_NONBLOCK: https://www.spinics.net/lists/io-uring/msg04058.html https://github.com/axboe/liburing/issues/364 Change-Id: Idba623730230bc049b827e51b058cd64d23b730f --- M src/core/osmo_io_uring.c 1 file changed, 22 insertions(+), 1 deletion(-) git pull ssh://gerrit.osmocom.org:29418/libosmocore refs/changes/71/41671/4 -- To view, visit https://gerrit.osmocom.org/c/libosmocore/+/41671?usp=email To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings?usp=email Gerrit-MessageType: newpatchset Gerrit-Project: libosmocore Gerrit-Branch: master Gerrit-Change-Id: Idba623730230bc049b827e51b058cd64d23b730f Gerrit-Change-Number: 41671 Gerrit-PatchSet: 4 Gerrit-Owner: pespin <pespin(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: daniel <dwillmann(a)sysmocom.de> Gerrit-Reviewer: fixeria <vyanitskiy(a)sysmocom.de> Gerrit-Reviewer: jolly <andreas(a)eversberg.eu> Gerrit-Reviewer: laforge <laforge(a)osmocom.org> Gerrit-Reviewer: osmith <osmith(a)sysmocom.de> Gerrit-Attention: osmith <osmith(a)sysmocom.de> Gerrit-Attention: jolly <andreas(a)eversberg.eu> Gerrit-Attention: laforge <laforge(a)osmocom.org> Gerrit-Attention: fixeria <vyanitskiy(a)sysmocom.de> Gerrit-Attention: daniel <dwillmann(a)sysmocom.de>
