In ipc_obtain_object_check we return -EIDRM when a bogus sequence number is detected via ipc_checkid, while the ipc manpages state the following return codes for such errors: EIDRM <ID> points to a removed identifier. EINVAL Invalid <ID> value, or unaligned, etc. EIDRM should only be returned upon a RMID call (->deleted check), and thus return EINVAL for wrong seq. This difference in semantics has also caused real bugs, ie: https://bugzilla.redhat.com/show_bug.cgi?id=246509 Signed-off-by: Davidlohr Bueso <dbueso@suse.de> Cc: Manfred Spraul <manfred@colorfullife.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |
