2010-09-09kernel/groups.c: fix integer overflow in groups_searchJerome Marchand
gid_t is a unsigned int. If group_info contains a gid greater than MAX_INT, groups_search() function may look on the wrong side of the search tree. This solves some unfair "permission denied" problems.

2009-06-16groups: move code to kernel/groups.cAlexey Dobriyan
Move supplementary groups implementation to kernel/groups.c . kernel/sys.c already accumulated quite a few random stuff. Do strictly copy/paste + add required headers to compile. Compile-tested on many configs and archs.
