Avoid copying out kernel pointers from msgctl(IPC_STAT). 2020-07-09T17:26:49+00:00 Mark Johnston markj@FreeBSD.org 2020-07-09T17:26:49+00:00 f4f16af1d38367e68bee456af2d7e284f6aad87d While this behaviour is harmless, it is really just an artifact of the fact that the msgctl(2) implementation uses a user-visible structure as part of the internal implementation, so it is not deliberate and these pointers are not useful to userspace. Thus, NULL them out before copying out, and remove references to them from the manual page.

Rename kernel-only members of semid_ds and msgid_ds. 2018-03-02T22:10:48+00:00 Brooks Davis brooks@FreeBSD.org 2018-03-02T22:10:48+00:00 93e48a303a74db9aa4ba9c48cb99f66c8fbeb840 This deliberately breaks the API in preperation for future syscall revisions which will remove these nonstandard members. In an exp-run a single port (devel/qemu-user-static) was found to use them which it did becuase it emulates system calls. This has been fixed in the ports tree.
