In preparation for raising NGROUPS and NGROUPS_MAX, change base
system callers of getgroups(), getgrouplist(), and setgroups() to
allocate buffers dynamically. Specifically, allocate a buffer of size
sysconf(_SC_NGROUPS_MAX)+1 (+2 in a few cases to allow for overflow).
This (or similar gymnastics) is required for the code to actually follow
the POSIX.1-2008 specification where {NGROUPS_MAX} may differ at runtime
and where getgroups may return {NGROUPS_MAX}+1 results on systems like
FreeBSD which include the primary group.
In id(1), don't pointlessly add the primary group to the list of all
groups, it is always the first result from getgroups(). In principle
the old code was more portable, but this was only done in one of the two
places where getgroups() was called to the overall effect was pointless.
Document the actual POSIX requirements in the getgroups(2) and
setgroups(2) manpages. We do not yet support a dynamic NGROUPS, but we
may in the future.
Added the EXIT STATUS section where appropriate.2005-01-17T07:44:44ZRuslan Ermilovru@FreeBSD.org2005-01-17T07:44:44Zurn:sha1:a866e170777b42fd7921eadd6e7e664f3a031d60Introduce the PRECIOUSPROG knob in bsd.prog.mk, similar2004-11-03T18:01:21ZRuslan Ermilovru@FreeBSD.org2004-11-03T18:01:21Zurn:sha1:dee651eb15eb85ae1b3bd54056277d1dde58d129

is making installing the world under jail(8) possible by
using another knob, NOFSCHG.

Without this cast the compiler cannot know that it has to convert
the null pointer constant NULL to a null pointer.
