Attention is currently required from: daniel, fixeria, jolly, laforge. Hello Jenkins Builder, daniel, fixeria, jolly, laforge, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/libosmo-netif/+/41666?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 The following approvals got outdated and were removed: Verified+1 by Jenkins Builder Change subject: cosmetic: stream_srv: srv_link: Document no need for OSMO_SOCK_F_NONBLOCK ...................................................................... cosmetic: stream_srv: srv_link: Document no need for OSMO_SOCK_F_NONBLOCK osmo_fd_register() currently takes care of setting the socket as non-blocking, before any blocking call is performed. Document it. If we ever switch from osmo_fd to io_uring to process the accept() op then we won't need to set the socket as nonblocking anyway, since io_uring expects to work with blocking sockets.

pespin has uploaded this change for review. ( https://gerrit.osmocom.org/c/libosmocore/+/41671?usp=email ) 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, 21 insertions(+), 1 deletion(-) git pull ssh://gerrit.osmocom.org:29418/libosmocore refs/changes/71/41671/1 diff --git a/src/core/osmo_io_uring.c b/src/core/osmo_io_uring.c index cac6272..278b686 100644 --- a/src/core/osmo_io_uring.c +++ b/src/core/osmo_io_uring.c @@ -534,6 +534,23 @@ static void iofd_uring_write_enable(struct osmo_io_fd *iofd); static void iofd_uring_read_enable(struct osmo_io_fd *iofd); +/* make an FD blockig: + * osmo_fd_register(ofd) did set fd flag O_NONBLOCK previously.
