Patch Set 2: (1 comment) File src/core/osmo_io.c: https://gerrit.osmocom.org/c/libosmocore/+/34144/comment/16aac7e4_4bd68661 PS2, Line 106: talloc_steal(iofd, msg); Here iofd_msghdr_alloc is called with a msg - this happens in the send path when a user calls osmo_iofd_{sendto,write}_msgb() The user could have any parent as msgb, that's why we need to talloc_steal() it here. Otherwise I could call talloc_steal() in each of the send functions individually. -- 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: 2 Gerrit-Owner: daniel <dwillmann(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: laforge <laforge(a)osmocom.org> Gerrit-CC: pespin <pespin(a)sysmocom.de> Gerrit-Attention: pespin <pespin(a)sysmocom.de> Gerrit-Comment-Date: Tue, 22 Aug 2023 15:30:21 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: pespin <pespin(a)sysmocom.de> Gerrit-MessageType: comment
