From 0c4d2abd9966366b5e215ae64ce3b620efca9335 Mon Sep 17 00:00:00 2001 From: Corinna Vinschen Date: Sun, 2 Jul 2000 10:17:44 +0000 Subject: * winsup.h: Define MAX_SID_LEN and new MAX_HOST_NAME. * fork.cc (fork): Use above defines instead of numerical constants. * shared.cc (sec_user): Ditto. * shared.h (class pinfo): Ditto. * syscall.cc (seteuid): Ditto. * spawn.cc (_spawnve): Ditto. Eliminate conditional. (spawn_guts): Set child->uid = USHRT_MAX when user context will be changed in child process. * uinfo.cc (uinfo_init): Check for myself->uid instead of myself->psid to avoid reloading of /etc/passwd on process startup if ntsec is off. Use above defines instead of numerical constants. * security.cc: Move define for MAX_SID_LEN to winsup.h. --- winsup/cygwin/spawn.cc | 20 +++++++++----------- 1 file changed, 9 insertions(+), 11 deletions(-) (limited to 'winsup/cygwin/spawn.cc') diff --git a/winsup/cygwin/spawn.cc b/winsup/cygwin/spawn.cc index 425094677..734d2d2bf 100644 --- a/winsup/cygwin/spawn.cc +++ b/winsup/cygwin/spawn.cc @@ -543,8 +543,9 @@ skip_arg_parsing: if (myself->impersonated && myself->token != INVALID_HANDLE_VALUE) seteuid (myself->orig_uid); - /* Set child->psid to NULL to force calling internal_getlogin() - from child process. */ + /* Set child->uid to USHRT_MAX to force calling internal_getlogin() + from child process.
