Recognize option -s, -c, and -l. 2000-04-20 Thorsten Kukuk * nscd/nscd.c: Start new session for nscd, drop privilegs to configured user if requested and no -S parameter are used. * nscd/nscd.conf: Add new option "server-user". * nscd/nscd_conf.c: Add support for new "server-user" option. * nscd/nscd.h: Add declaration for server_user variable. Based on patch by Chris Wing 2000-04-29 Mark Kettenis * sysdeps/unix/sysv/linux/i386/sigaction.c: Add comment explaining that changing the __restore and __restore_rt signal return code will break GDB. 2000-04-29 Mark Kettenis * sysdeps/unix/sysv/linux/i386/sys/ucontext.h: Do not include . 2000-04-29 Mark Kettenis * conform/data/ucontext.h-data: Allow ss_* instead of SS_*. 2000-04-29 Ulrich Drepper --- sysdeps/unix/sysv/linux/i386/sigaction.c | 14 +++++++++++--- sysdeps/unix/sysv/linux/i386/sys/ucontext.h | 4 ---- 2 files changed, 11 insertions(+), 7 deletions(-) (limited to 'sysdeps/unix/sysv/linux') diff --git a/sysdeps/unix/sysv/linux/i386/sigaction.c b/sysdeps/unix/sysv/linux/i386/sigaction.c index 2571f1d922..5e431218e9 100644 --- a/sysdeps/unix/sysv/linux/i386/sigaction.c +++ b/sysdeps/unix/sysv/linux/i386/sigaction.c @@ -148,12 +148,20 @@ __sigaction (int sig, const struct sigaction *act, struct sigaction *oact) weak_alias (__sigaction, sigaction) +/* NOTE: Please think twice before making any changes to the bits of + code below.
