From a97e5e25576cb5e207b1e49f1eb4e52e6354daa7 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Wed, 17 Jun 2015 20:09:35 +0000 Subject: Fix vsyslog namespace (bug 18533). syslog functions (in POSIX) bring in the strong symbol vsyslog (not in POSIX). This patch fixes this by changing this symbol from a strong alias to a weak alias. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). (vsyslog becomes weak in the static libraries, which is what's needed; the particular macro sequence in use leaves it as strong in the shared libraries, hence those libraries being completely unchanged, but it doesn't generally matter whether symbols exported from the shared libraries are weak or strong.) [BZ #18533] * misc/syslog.c (vsyslog): Define as a weak alias of __vsyslog, not a strong alias. * conform/Makefile (test-xfail-XOPEN2K8/syslog.h/linknamespace): Remove variable. --- ChangeLog | 6 ++++++ NEWS | 3 ++- conform/Makefile | 1 - misc/syslog.c | 2 +- 4 files changed, 9 insertions(+), 3 deletions(-) diff --git a/ChangeLog b/ChangeLog index bfd78a8..3d03d20 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,5 +1,11 @@ 2015-06-17 Joseph Myers + [BZ #18533] + * misc/syslog.c (vsyslog): Define as a weak alias of __vsyslog, + not a strong alias. + * conform/Makefile (test-xfail-XOPEN2K8/syslog.h/linknamespace): + Remove variable. + [BZ #18532] * inet/in6_addr.c (in6addr_any): Rename to __in6addr_any and define as weak alias of __in6addr_any.
