2010-05-03nptl: use arch-specific pthread_cond_timedwait and pthread_cond_wait on x86_64Roman I Khimov
Generic ones were broken on x86_64, pthread/ex2 test failed while pthread/ex5 worked fine. So use arch-specific functions and fix linkage failure with __pthread_mutex_cond_lock_adjust. Signed-off-by: Roman I Khimov <khimov@altell.ru> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
2010-05-03nptl: use arch-specific cancellation routines for x86_64Roman I Khimov

2010-05-03nptl: fix sem_open with O_CREATRoman I Khimov
Temporary file name template passed to __gen_tempname had no "XXXXXX" in it, so __gen_tempname returned EINVAL which led to sem_open failure. Fixes NPTL tests tst-sem4, tst-sem7, tst-sem8, tst-sem9.

2010-04-27MIPS: restore INLINE_SYSCALL macroGabor Juhos
The MIPS specific INLINE_SYSCALL macro has been renamed to INLINE_SYSCALL_NCS with: 763bbf9e9a27426c9be8322dca5ddf2cb4dbc464 syscall: unify part 2: NCS variety Declare common NCS (non-constant syscall) variants and convert the existing ports over to this. This change breaks system calls. The code generated with using of the new macro does not obey the restartable syscall convention used by the linux kernel. When it tries to restart the syscall the errno value is not being replaced by the syscall number. This causes weird behaviour of the 'ping' command in busybox for example: root@OpenWrt:/# ping 192.168.1.254 PING 192.168.1.254 (192.168.1.254): 56 data bytes 64 bytes from 192.168.1.254: seq=0 ttl=128 time=6.292 ms ping: recvfrom: Function not implemented 64 bytes from 192.168.1.254: seq=1 ttl=128 time=0.719 ms ping: recvfrom: Function not implemented 64 bytes from 192.168.1.254: seq=2 ttl=128 time=0.489 ms ping: recvfrom: Function not implemented 64 bytes from 192.168.1.254: seq=3 ttl=128 time=0.486 ms ping: recvfrom: Function not implemented 64 bytes from 192.168.1.254: seq=4 ttl=128 time=0.487 ms ping: recvfrom: Function not implemented 64 bytes from 192.168.1.254: seq=5 ttl=128 time=0.939 ms ping: recvfrom: Function not implemented 64 bytes from 192.168.1.254: seq=6 ttl=128 time=0.971 ms ping: recvfrom: Function not implemented 64 bytes from 192.168.1.254: seq=7 ttl=128 time=0.488 ms ping: recvfrom: Funct^C Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>

2010-04-27libc/x86_64: use ELF-compatible definitions for assemblerRoman I Khimov
Fixes open/read/write/close breakage with NPTL on x86_64 (due to missing '.type' declaration). Done this way because there are already ELF-style definitions in assemebler code for x86_64 and looks like HAVE_ELF is not defined and used this days. Or the other way around, it'd be a bit strange for x86_64 not to have ELF. Signed-off-by: Roman I Khimov <khimov@altell.ru> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>

2010-04-22nptl: fix dynamic initialization of libpthreadTimo Teräs
If libpthread get's pulled in via dlopen(), we need to do libpthread initialization in dlopen(). Achieve this by making initializer function out of __pthread_initialize_minimal_internal. Add the proper linker flags and make it callable multiple times. Add also nodelete flag which ensures that libpthread will not get unmapped after it's been loading. Though, ld.so does not yet support this. Signed-off-by: Timo Teräs <timo.teras@iki.fi> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
2010-04-22nptl: fix libc internal, dynamically enabled lockingTimo Teräs
Final iteration to fix libc internal locking if libpthread is pulled in by dlopen call (directly or indirectly). We cannot really use the weak symbol trick for shared build, since the symbols won't get refreshed if libpthread is pulled in dynamically. In glibc, they have #ifdef SHARED magic to either use pthread_functions table, or weaks. But as we shared object files with both builds, this does not sounds good either. The reintroduces the libc weaks.c, but uses them now only with static build. For dynamic build, we still use the symbols with same name, but provide weaks in forward.c so they end up dereferencing the pthread_functions table indirectly if we are not linked to libpthread. Mutex initialization is hard coded as inline, as it needs to happen even if libpthread is not initially loaded.

2010-04-22ldso: support RTLD_NODELETE and DF_1_NODELETETimo Teräs

2010-04-22nptl: fix warnings of shadowing __selfTimo Teräs

2010-04-22nptl: proper soname handlingNatanael Copa

2010-04-20nptl: remove unneeded libc-lock.h includeTimo Teräs
I semi-accidentally added include for libc-lock.h because the intention was to use locking macroes from there. However, we ended up using using the weak alias stuff. This is additionally good since now this can result in compile errors like: In file included from /toolchain/include/bits/uClibc_mutex.h:16, from /toolchain/include/bits/uClibc_stdio.h:107, from /toolchain/include/stdio.h:72, from /work/freetype-2.3.11/include/freetype/config/ftstdlib.h:100, from ./builds/unix/ftconfig.h:43, from builds/unix/ftsystem.c:21: /toolchain/include/bits/libc-lock.h:309: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'void' Remove the unneeded include causing breakage.

2010-04-16nptl: mark forwarded functions protectedTimo Teras

2010-04-16libc: remove libc weak __pthreads_* wrappersTimo Teras
It is not possible to override for libpthread to override the weak libc definitions. This has never worked in uclibc, and does no longer work in glibc either (unless you use LD_DYNAMIC_WEAK). The proper thing to do is have weak prototypes in libc, and definitions in libpthread only. This way libc runs even if those functions are not defined, but just needs to protect against the NULL values (done by implementing __uclibc_maybe_call). This fix the problems if libc is linked before libpthread or if libpthread is pulled by a dependency library.

This reverts most of commit 1610762362e651f86ca284ac59a1d7ec88034e4e. Marking the symbols hidden is wrong, because libc accesses the pthreads internal symbols for internal locking. Signed-off-by: Timo Teras <timo.teras@iki.fi> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
2010-04-15nptl: fix libc sigtimedwaitTimo Teräs
It seems that 57e8823548ad6e65d33b2153edeb18fb0edc20e6 removed completely sigtimedwait symbol from libc which is wrong. I hope there is not too many other things like this. Apparently the libc_hidden_* macros actually make previously hidden symbols visible globally (creates alias from __GI_* to *). This is probably ancient confusion from times when gcc did not support visibility attribute and hiding symbols was done using hacks like this. This also adds attribute_hidden to the internal __sigtimedwait for nptl case. Signed-off-by: Timo Teräs <timo.teras@iki.fi> Signed-off-by: Austin Foxley <austinf@cetoncorp.com>
2010-04-15nptl: fix libc sigaction signal checkingTimo Teräs
We should not check for SIGCANCEL in __libc_sigaction because nptl calls this function to setup this signal. Nptl provides it's own override for sigaction that checks that the user cannot override signals nptl uses internally. Linuxthreads does not use SIGCANCEL at all so this affects nptl only.

2010-04-14nptl: turn pointer demangling offTimo Teräs
Currently the stub calls would demangle the pointer that is never mangled. Alternatively, we could sync nptl/sysdeps/unix/sysv/linux/libc_pthread_init.c with new glibc version that properly mangles the pointers, but that would need more validation to make sure that all struct pthread_function readers do demangling. uclibc currently does not do pointer mangling everywhere so it's more consistent to just disable it here too.

2010-04-14nptl: mark symbols with libc forwarder hiddenTimo Teräs
Add attribute_hidden to all symbols having libc forwarder. This prevents recursive self calls which would happen if libc is before libpthread in linking order: the forwarder functions would call itself via the function table, since the libpthread symbols would get overwritten with libc ones. This has not been a problem in glibc since there these symbols are marked hidden with linker version-script. Since we don't use one, we need to mark these explicitly.
