	3e035a5d	2009-12-04T08:26:23		mgetgroups: add xgetgroups, and avoid ENOSYS failures ENOSYS implies that there are no supplemental groups, so we can treat it the same as a return of 0 from getgroups rather than exposing failure to the user. This in turn fixes a crash in coreutils' id, which freed an uninitialized pointer. * lib/mgetgroups.h (xgetgroups): New prototype. * lib/mgetgroups.c (xgetgroups): New wrapper. (mgetgroups): Handle ENOSYS. * modules/mgetgroups (Depends-on): Add realloc. Reported by Scott Harrison <scott.gnu.2009@scottrix.co.uk>. Signed-off-by: Eric Blake <ebb9@byu.net>
	8c4c7e9f	2009-11-12T11:31:52		mgetgroups: new module, taken from coreutils Wrapper function that makes using getgroups/getugroups easier to use. As part of the move from coreutils, convert GETGROUPS_T to gid_t, and allow mgetgroups(NULL,getegid(),&list) as a way to ensure that the effective gid is in the list. * modules/mgetgroups: New file. * lib/mgetgroups.h: Likewise. * lib/mgetgroups.c (mgetgroups): Likewise. * m4/mgetgroups.m4 (gl_MGETGROUPS): Likewise. * MODULES.html.sh (Users and groups): Mention it.
