Patch Set 3: (1 comment) Patchset: PS3: Not sure if I understood you correctly. For the receive side: In the poll backend the msghdr is only a local variable that goes out of scope as soon as iofd_poll_ofd_cb_recvmsg_sendmsg() returns, in io_uring the msghdr is free()d at the end of iofd_uring_handle_recv(). In both cases I expect the user might want to keep msg around for longer. Then there's msg->pending which is a msg from (a/multiple) previous receive call so it's not clear what msghdr(s) it belongs to anymore. -- To view, visit https://gerrit.osmocom.org/c/libosmocore/+/34144 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: libosmocore Gerrit-Branch: master Gerrit-Change-Id: I3a279b55a3adff96948120683c844e1508d0ba94 Gerrit-Change-Number: 34144 Gerrit-PatchSet: 3 Gerrit-Owner: daniel <dwillmann(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: laforge <laforge(a)osmocom.org> Gerrit-Reviewer: pespin <pespin(a)sysmocom.de> Gerrit-Attention: pespin <pespin(a)sysmocom.de> Gerrit-Comment-Date: Wed, 23 Aug 2023 17:20:41 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: pespin <pespin(a)sysmocom.de> Gerrit-MessageType: comment
