[M] Change in osmo-mgw[master]: migrate mgcp_client from osmo_wqueue to osmo_io

Attention is currently required from: jolly, pespin. laforge has posted comments on this change. ( https://gerrit.osmocom.org/c/libosmo-netif/+/36123?usp=email ) Change subject: stream_cli: Do not try to send msg, if not connected ...................................................................... Patch Set 4: Code-Review+1 (1 comment) File src/stream_cli.c: https://gerrit.osmocom.org/c/libosmo-netif/+/36123/comment/e041ae26_cd2e9bc8 PS4, Line 998: if (cli->state != STREAM_CLI_STATE_CONNECTED) { > Is this really a problem? or will the socket enqueue the data and transmit it automatically after co […] I think with the osmo_fd mode it is indeed just enqueued in our own internal write_queue which might be drained once connect is complete. However, for osmo_io, there is no in-application/library write_queue. Instead we immediately submit the write into the io_uring submission queue. It's illegal to do a write on a socket before it is connected. See https://pubs.opengroup.org/onlinepubs/9699919799/functions/write.html: [ECONNRESET] A write was attempted on a socket that is not connected. -- To view, visit https://gerrit.osmocom.org/c/libosmo-netif/+/36123?usp=email To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: libosmo-netif Gerrit-Branch: master Gerrit-Change-Id: I9e5f5db9b45615dacb05115c4de8ff3f715815c8 Gerrit-Change-Number: 36123 Gerrit-PatchSet: 4 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: pespin <pespin(a)sysmocom.de> Gerrit-Comment-Date: Sat, 02 Mar 2024 09:33:43 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: Yes Comment-In-Reply-To: pespin <pespin(a)sysmocom.de> Gerrit-MessageType: comment

[S] Change in libosmo-netif[master]: stream_{cli,srv}: Free received messages when not forwarded
by laforge 02 Mar '24

02 Mar '24

laforge has submitted this change. ( https://gerrit.osmocom.org/c/libosmo-netif/+/36125?usp=email ) ( 4 is the latest approved patch-set. No files were changed between the latest approved patch-set and the submitted one. )Change subject: stream_{cli,srv}: Free received messages when not forwarded ...................................................................... stream_{cli,srv}: Free received messages when not forwarded If a message is not forwarded (to a read callback function, it must be freed, to prevent memory leaks. The message musst be freed before calling osmo_stream_srv_destroy() or stream_cli_handle_connecting(), because within the function calls the client/server instance may get destroyed and the message is 'owned' by it. Calling msgb_free(msg) afterwards may result in double free bug.
