Bug ID: 18536
Summary: sem_* tdelete, tfind, tsearch, twalk namespace
Product: glibc
Version: 2.21
Status: NEW
Severity: normal
Priority: P2
Component: nptl
Assignee: unassigned at sourceware dot org
Reporter: jsm28 at gcc dot gnu.org
CC: drepper.fsp at gmail dot com
Target Milestone: ---
The sem_* functions bring in references to tdelete, tfind, tsearch and twalk.
But the t* functions are XSI-shaded, while sem_* aren't.
[initial] sem_close -> [libpthread.a(sem_close.o)] tdelete
[initial] sem_open -> [libpthread.a(sem_open.o)] tfind
[initial] sem_open -> [libpthread.a(sem_open.o)] tsearch
[initial] sem_close -> [libpthread.a(sem_close.o)] twalk

Fix sem_* tdelete, tfind, tsearch, twalk namespace (bug 18536).
The sem_* functions bring in references to tdelete, tfind, tsearch and
twalk. But the t* functions are XSI-shaded, while sem_* aren't. This
patch fixes this by using __t* instead, exporting those functions from
libc at version GLIBC_PRIVATE (since sem_* are in libpthread) and
using libc_hidden_* for the benefit of calls within libc.
Tested for x86_64 and x86 (testsuite, and comparison of disassembly of
installed stripped shared libraries). libpthread gets changes from
PLT reordering; addresses in libc change because of PLT / dynamic
symbol table changes.
[BZ #18536]
* misc/tsearch.c (__tsearch): Use libc_hidden_def.
(__tfind): Likewise.
(__tdelete): Likewise.
(__twalk): Likewise.
* misc/Versions (libc): Add __tdelete, __tfind, __tsearch and
__twalk to GLIBC_PRIVATE.
* include/search.h (__tsearch): Use libc_hidden_proto.
(__tfind): Likewise.
(__tdelete): Likewise.
(__twalk): Likewise.
* nptl/sem_close.c (sem_close): Call __twalk instead of twalk.
Call __tdelete instead of tdelete.
* nptl/sem_open.c (check_add_mapping): Call __tfind instead of
tfind. Call __tsearch instead of tsearch.
* sysdeps/sparc/sparc32/sem_open.c (check_add_mapping): Likewise.
* conform/Makefile (test-xfail-POSIX/semaphore.h/linknamespace):
Remove variable.
(test-xfail-POSIX2008/semaphore.h/linknamespace): Likewise.
