* sysdeps/mach/hurd/setuid.c: Rewrote ID frobnication to do the right thing. * sysdeps/mach/hurd/setgid.c: Likewise. * sysdeps/mach/hurd/setreuid.c: Likewise. * sysdeps/mach/hurd/setregid.c: Likewise. * sysdeps/mach/hurd/setegid.c: Likewise. * sysdeps/mach/hurd/seteuid.c: Likewise. * sysdeps/mach/hurd/fork.c: Peek __mach_task_self_ value before proc_dostop call to work around kernel paging bug. Thu Dec 21 12:19:32 1995 Miles Bader <miles@gnu.ai.mit.edu> * sysdeps/mach/hurd/setuid.c (__setuid): Actually add the new uid instead of putting it (and other uids) in the gids and leaving the old uids as is.
