Author: ngie Date: Mon May 29 06:26:00 2017 New Revision: 319095 URL: https://svnweb.freebsd.org/changeset/base/319095 Log: MFC r316179,r316180,r316181,r316260: r316179 (by cem): t_msgsnd: Use msgsnd()'s msgsz argument correctly to avoid overflow msgsnd's msgsz argument is the size of the message following the 'long' message type. Don't include the message type in the size of the message when invoking msgsnd(2). CID: 1368712 r316180 (by cem): Follow-up to r316179: More of the same CIDs: 1368705, 1368706, 1368707, 1368710 r316181 (by cem): t_msgctl: Fix the same msgsnd() misuse as t_msgsnd msgsnd(2)'s msgsz argument does not describe the full structure, only the message component. CIDs: 1368703, 1368711 r316260: Annotate all changes made in r316178-r316180 with __FreeBSD__ Restore the stock (upstream) code under an #else block, so it's easier for me to visualize and understand the code that needs to be upstreamed.
