2023-11-09libpthread/nptl: make default stack size configurableBen Wolsieffer
Threads currently have 2-4 MiB stacks by default (depending on the platform). This is fine on MMU platforms, where this stack space is not actually allocated until it is used, but tends to waste a large amount of memory on no-MMU platforms. This patch adds a PTHREADS_STACK_DEFAULT_SIZE Kconfig option that allows the user to override the default stack size at build time. This allows the user to select a reasonable default stack size for the software that runs on their system, and avoids the need to patch every package to add calls to pthread_attr_setstacksize(). An alternative to this patch would be to change the hardcoded default stack size on no-MMU platforms, but it is difficult to choose an appropriate value because the minimum required stack depends on the software in use. This would also be a breaking change. Signed-off-by: Ben Wolsieffer <ben.wolsieffer@hefring.com>
2020-07-02Rename __unused struct members to include a namespaceEd Wildgoose
Rename various spare fields in structs to include a namespace This should avoid accidental clashes with uses of the __unused symbol in upstream projects. eg currently it causes a compile error in dhcpcd 8.x due to their re-use of the __unused symbol as a macro This follows the style of glibc which does something equivalent

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.

2010-11-11ntpl: fix static linking by not leaking SSP_ALL_CFLAGSNatanael Copa
The SSP_ALL_CFLAGS in nptl arch CFLAGS leaks out and forces things like dl-support.c, brk.c, sbrk.c memcpy, etc to be built with -fstack-protector-all. This is bad when linking statically since initializing TLS will call those functions before SSP is initialized. The libpthread itself will still be built with -fstack-protector-all due to CFLAGS-nptl has SSP_ALL_CFLAGS in libpthread/nptl/Makefile.in Thanks to Timo Teras for helping with this.
