From 9962e7fd037872c423544f61cba1c901b045363a Mon Sep 17 00:00:00 2001 From: guenther Date: Wed, 21 Oct 2009 16:04:23 +0000 Subject: Fix the handle locking in stdio to use flockfile/funlockfile internally when and where required. Macros in are updated to automatically call the underlying functions when the process is threaded to obtain the necessary locking. A private mutex is added to protect __sglue, the internal list of FILE handles, and another to protect the one-time initialization. Some routines in libc that use getc() change to use getc_unlocked() as they're either protected by their own lock or aren't thread-safe routines anyway. ok kurt@, earlier version tested by sthen@ and jj@ --- lib/libc/gen/getgrouplist.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'lib/libc/gen/getgrouplist.c') diff --git a/lib/libc/gen/getgrouplist.c b/lib/libc/gen/getgrouplist.c index d8dff264d8a..564ca8fb3c1 100644 --- a/lib/libc/gen/getgrouplist.c +++ b/lib/libc/gen/getgrouplist.c @@ -1,4 +1,4 @@ -/* $OpenBSD: getgrouplist.c,v 1.18 2009/06/23 18:52:43 schwarze Exp $ */ +/* $OpenBSD: getgrouplist.c,v 1.19 2009/10/21 16:04:23 guenther Exp $ */ /* * Copyright (c) 2008 Ingo Schwarze * Copyright (c) 1991, 1993 @@ -123,7 +123,7 @@ _read_netid(const char *key, uid_t uid, gid_t *groups, int *ngroups, *p = '\0'; else { /* Skip lines that are too long. */ int ch; - while ((ch = getc(fp)) != '\n' && ch != EOF) + while ((ch = getc_unlocked(fp)) != '\n' && ch != EOF) ; continue; } -- cgit v1.2.3-59-g8ed1b
