| | | | | | | | | | Revert previous commit. We still want to call setgroups in the case where there are zero groups to remove any that we might otherwise inherit (as pointed out by grawity at gmail.com) and since the 2nd argument to setgroups is always a static global it's always valid to dereference in this case. ok deraadt@ djm@ Upstream-ID: 895b5ac560a10befc6b82afa778641315725fd01

* upstream commitderaadt@openbsd.org2015-01-161-2/+2
| | | | | | | | | | Replace <sys/param.h> with <limits.h> and other less dirty headers where possible. Annotate <sys/param.h> lines with their current reasons. Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution. These are the files confirmed through binary verification. ok guenther, millert, doug (helped with the verification protocol)
