2017-11-22librt: fix broken posix_spawnWaldemar Brodkorb
Fix iteration over signals, synced with GNU C library code and pending patches. Issues found when running dhcpcd with hook scripts. (exit status 127) Reported-By: kapeka <kapeka@bering-uclibc.de>
2017-11-19csky: port to uclibc-ngGuo Ren
Follow the steps to build c-sky uclibc linux system: 1. git clone https://github.com/c-sky/buildroot.git 2. cd buildroot 3. make qemu_csky_ck810_uclibc_defconfig 4. make Follow the buildroot/board/qemu/csky/readme.txt to run. This buildroot toolchain is pre-build, But you can rebuild the c-sky uclibc-ng alone and install it to the buildroot sysroot manually. We'll try our best to improve the uclibc-ng continuously.

2017-11-19linuxthreads: add dummy for pthread_atforkWaldemar Brodkorb
For noMMU targets we need a pthread_atfork dummy, otherwise libraries like libressl using pthread_atfork, but not fork() for itself, can not be used. But software like curl with ssl support linking against libressl still work fine on noMMU targets.

2017-10-01recvmmsg/sendmmsg: add recvmmsg sendmmsg support.Guo Ren
The recvmmsg and sendmmsg is very important for UDP stream application. If we only use recvmsg for UDP stream, it will only copy one mtu size of data in a syscall. And recvmmsg copy as many as you want in a syscall. So recvmmsg is more efficient,and some applications will depends on the recvmmsg and sendmmsg, eg: UDP media stream player.

2017-08-19fix compile issue when DOASSERTS=yWaldemar Brodkorb
Pthread pid caching was removed recently but an assert is still present which checks pthread->pid, and this breaks the build when debugging is enabled. Reported-By: Bogdan Harjoc <harjoc@gmail.com>
2017-08-05fix issues with gdb 8.0Waldemar Brodkorb
GDB 8.0 is compiled and linked with g++, but the linking of static targets (f.e. coldfire) fails, without declaring the functions in thread_db.h extern C. The compilation of gdb errors out with: thread-db.o: In function `thread_db_init()': thread-db.c:(.text+0x5b6): undefined reference to `td_ta_new(ps_prochandle*, td_thragent**)' thread-db.c:(.text+0x61e): undefined reference to `td_thr_get_info(td_thrhandle const*, td_thrinfo*)' thread-db.c:(.text+0x632): undefined reference to `td_symbol_list()' ..

2017-03-20remove RPC implementationWaldemar Brodkorb
The included RPC implementation is ipv4 only. Other C library projects have either deprecated the internal RPC implementation (GNU C Library) or never implemented such functionality (musl C Library). The latest rpcbind release (0.2.4) checks for libtirpc and does not allow to be build with uClibc-ng RPC without patching. The common use case for RPC nowadays is to use rpcbind together with nfs-utils to provide NFS server or client support to a system. The included RPC implementation does create issues with duplicate symbol failures when statically compiling with RPC enabled.
2017-02-17arm: fix static linking issuesWaldemar Brodkorb
As reported by Buildroot developers these files causing static linking issues. The original contribution with the ARM unwind-resume rework and GNU libc sync was made before the combined libc change. But the patch was applied later, after the libc change and it seems the test coverage for static linking didn't catch it in the regression testing. Remove the files.

2017-01-22nds32: add NPTL/TLS, *context function, libm changes and code cleanupVincent Ren-Wei Chen
This commit includes following features. 1. Support NPTL/TLS 2. Add libm function which is used to handle FP rounding and excpetions (ex: fclrexcpt,fedisblxcpti,feenablxcpt... ) 3. Add *context function for operating user context (ex: setcontext,getcontext,makecontext... ) 4. Change the return flow from signal handler 5. Cleanup of old code The testsuite only has 2 errors, tst-cpuclock1 and tst-cputimer1, which are related to timing accuracy.

2016-12-10xtensa: fix static linkingWaldemar Brodkorb
uClibc-ng 1.0.20 fixed static linking with "libdl" by adding all libdl functions into the libc. On xtensa, though, libdl contains an unresolved reference that is satisfied by the ld.so - which is not a part of the linking in a static case.

As __UCLIBC_HAS_GETTEXT_AWARENESS__ is never defined, this is mostly dead code. It is planned to integrate libiconv-tiny and gettext-tiny into uClibc-ng after the next release, so that more software packages can be used without modification. Remove any _/_N macro usage.

Since librt and libpthread are now integrated into libc, including unwind-resume and unwind-forcedunwind implementations of unwind code makes no sense. Only unwind-forcedunwind is now included with functions hidden to avoid them overriding the ones from libgcc_s. * libpthread/nptl/sysdeps/generic/unwind-resume.h: New. Define generic PERSONALITY_PROTO and PERSONALITY_ARGS and set HAVE_ARCH_UNWIND_RESUME to 0. * libpthread/nptl/sysdeps/pthread/unwind-resume.c: Move... * libpthread/nptl/sysdeps/generic/unwind-resume.c: ... here. Include generic implementation of _Unwind_Resume on the condition that !HAVE_ARCH_UNWIND_RESUME. Make functions hidden to prevent them from overriding libgcc_s's ones. * libpthread/nptl/sysdeps/pthread/unwind-forcedunwind.c: Likewise. * libpthread/nptl/sysdeps/arm/unwind-resume.h: New.
