From 0595c98494c25f8eaa1a3298e8fa032ad5e4405e Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Wed, 17 Jun 2015 20:20:08 +0000 Subject: Fix mq_notify socket, recv namespace (bug 18546). mq_notify (in the 1996 edition of POSIX) brings in references to recv and socket (not in POSIX until the 2001 edition). This patch fixes this by using __recv and __socket, exporting them from libc at version GLIBC_PRIVATE. Tested for x86_64 and x86 (testsuite and comparison of installed stripped shared libraries; PLT / dynamic symbol table changes render the comparison not particularly useful for libc). [BZ #18546] * socket/recv.c (__recv): Use libc_hidden_def. * socket/socket.c (__socket): Likewise. * sysdeps/mach/hurd/recv.c (__recv): Likewise. * sysdeps/mach/hurd/socket.c (__socket): Likewise. * sysdeps/unix/sysv/linux/generic/recv.c (__recv): Likewise. * sysdeps/unix/sysv/linux/recv.c (__recv): Use libc_hidden_weak. * sysdeps/unix/sysv/linux/socket.c (__socket): Use libc_hidden_def. * sysdeps/unix/sysv/linux/x86_64/recv.c (__recv): Use libc_hidden_weak. * include/sys/socket.h (__socket): Do not use attribute_hidden. Use libc_hidden_proto. (__recv): Likewise. * socket/Versions (libc): Export __recv and __socket at version GLIBC_PRIVATE. * sysdeps/unix/sysv/linux/mq_notify.c (helper_thread): Call __recv instead of recv. (init_mq_netlink): Call __socket instead of socket. * conform/Makefile (test-xfail-POSIX/mqueue.h/linknamespace): Remove variable. --- NEWS | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'NEWS') diff --git a/NEWS b/NEWS index 004d769..1892800 100644 --- a/NEWS +++ b/NEWS @@ -22,7 +22,7 @@ Version 2.22 18324, 18333, 18346, 18397, 18409, 18410, 18412, 18418, 18422, 18434, 18444, 18468, 18469, 18470, 18479, 18483, 18495, 18496, 18497, 18498, 18507, 18512, 18519, 18520, 18522, 18527, 18528, 18529, 18530, 18532, - 18533, 18534, 18536, 18539, 18540, 18542, 18544, 18545. + 18533, 18534, 18536, 18539, 18540, 18542, 18544, 18545, 18546. * Cache information can be queried via sysconf() function on s390 e.g. with _SC_LEVEL1_ICACHE_SIZE as argument. -- cgit v1.1
