[Bug libc/1080] possible buffer misalignment in nscd; possible poll error on signal to nscd; bogus pointer in munmap in nscd


------- Additional Comments From cvs-commit at gcc dot gnu dot org  2005-07-18 08:01 -------
Subject: Bug 1080

CVSROOT:	/cvs/glibc
Module name:	libc
Branch: 	glibc-2_3-branch
Changes by:	roland@sources.redhat.com	2005-07-18 08:01:46

Modified files:
	nscd           : nscd_helper.c 

Log message:
	2005-07-13  Ulrich Drepper  <drepper@redhat.com>
	
	* nscd/nscd_helper.c: Add a few __builtin_expect.
	[BZ #1080]
	* nscd/connections.c (send_ro_fd): Make sure BUF is aligned correctly.
	* nscd/nscd_helper.c (wait_on_socket): New function.
	(get_mapping): Use wait_on_socket instead of poll.  The former handles
	EINTR of poll correctly.
	(__nscd_open_socket): Likewise.
	(get_mapping): Make sure BUF is aligned correctly.
	(get_mapping): Use munmap on correct pointer.

Patches:
