2021-04-18libpthread/nptl: create timer thread with sufficiant stack size (account for ↵Peter Seiderer
TLS) Create timer thread with sufficiant stack size (take into account allocated space for thread-local-storage), for this backport glibc commit 'Create internal threads with sufficient stack size' ([1], [2]) introducing __pthread_get_minstack() and use it in __start_helper_thread(). Fixes timer_create() in case of linking with library using large TLS area (e.g openblas, see [3]).

2018-12-14several patches for uclibc nghan_mao@c-sky.com
I've got several patches to fix ltp/openmp/uclibc-ng-test testcase fail on c-sky. - fix a ltp testcase. - fix the problem that pthread creat will fail when libomp is linked before libc, the variable pagesize is not init. - fix tst-cancel4 and tst-cancel16. tst-cancelx4 and tst-cancelx16 still fail with this patch applied, cleanup handler is not called for open/creat/fcntl, seems some thing wrong with unwind, I haven't check the rootcause yet.

2017-01-28remove PID cachingWaldemar Brodkorb
Follow GNU C Library from c579f48edba88380635ab98cb612030e3ed8691e and remove the PID caching. These simplifies the architecture specific assembly code. The run of the test suite found no regressions, it even solves some of the test failures for x86/x86_64/sparc.

2016-09-26use a single libc and deduplicate threading codeWaldemar Brodkorb
Similar to musl libc a single libc has many benefits and solves some open issues with uClibc-ng. - no pthread_mutex_* weak symbols exported anymore - applications no longer failing to link when either -lrt or -lpthread are missing for dynamic and static linking mode - smaller C library - slightly better runtime performance

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>

2010-04-14nptl: 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.
