2010-07-06Revert "don't make __errno_location / __h_errno_location hidden"Austin Foxley

2010-07-05don't make __errno_location / __h_errno_location hiddenPeter Korsgaard
Closes #2089 (https://bugs.busybox.net/show_bug.cgi?id=2089) __errno_location / __h_errno_location access has to go through the PLT like malloc/free, so the linuxthread variants gets used instead when compiling with -pthread.

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 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.

2010-04-20nptl: 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.

2010-04-16libc: 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.

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.
