* libc.so can't be unloaded, so move the hidden atexit() and pthread_atfork()guenther2015-11-101-1/+13
| | | | | | | | | | | stubs for the executable from crtbegin.o into libc, which lets them be excluded from static links that don't use them. For this, drop the normal crt{begin,end}S.o from libc.so: the .init and .fini sections for libc aren't called at the right times anyway, so it's good that they're unused. libc.so just needs __guard_local and the .note.openbsd.ident section, so add them to stack_protector.c for now (this will be improved) "good time" deraadt@

* Merge the sigaction() and sigprocmask() overloads/wrappers from libpthreadguenther2015-10-231-4/+3
| | | | | | | | | into libc, and move pthread_sigmask() as well (just a trivial wrapper). This provides consistent handling of SIGTHR between single- and multi-threaded programs and is a step in the merge of all the libpthread overloads, providing some ASM and Makefile bits that the other wrappers will need. ok deraadt@ millert@

| | | | | | | | | | | | | | | | | to returning strong random by default, source from arc4random(3). Parameters to the seeding functions are ignored, and the subsystems remain in strong random mode. If you wish the standardized deterministic mode, call srand_deterministic(), srandom_determistic(), srand48_deterministic(), seed48_deterministic() or lcong48_deterministic() instead. The re-entrant functions rand_r(), erand48(), nrand48(), jrand48() are unaffected by this change and remain in deterministic mode (for now). Verified as a good roadmap forward by auditing 8800 pieces of software. Roughly 60 pieces of software will need adaptation to request the deterministic mode. Violates POSIX and C89, which violate best practice in this century. ok guenther tedu millert
