Patch Set 6: (2 comments) File src/core/osmo_io.c: https://gerrit.osmocom.org/c/libosmocore/+/40584/comment/ae43fbd2_c3c7a258?… : PS5, Line 338: pending = iofd_msgb_alloc2(iofd, msgb_length(iofd->pending) + msgb_length(msg)); The code path of iofd_msgb_alloc2 is called, if the msg would not fit into the tailroom of iofd->pending. This implies that the length of data in iofd->pending plus the lengh of data in msg exceed the iofd->msgb_alloc.size. The allocated message will have a size that is greater.
