* Clarify conditions in which pthread_mutex_destroy(3) returns EBUSY.stsp2020-04-031-3/+3
| | | | | | | It happens not just if the mutex is locked by another thread, but also if any other threads refer to the mutex (e.g. by waiting for the lock). ok guenther

* Move sigwait(3) from libpthread to libcjca2019-01-122-87/+1
| | | | | | | | POSIX wants it in libc, that's where the function can be found on other systems. Reported by naddy@, input from naddy@ and guenther@. "looks ok" guenther@, ok deraadt@ Note: riding the libc/libpthread major cranks earlier today.
* Validate timespec and return ECANCELED when interrupted with SA_RESTART.pirofti2018-04-241-2/+17
| | | | | | | | | | | | | | | Discussing with mpi@ and guenther@, we decided to first fix the existing semaphore implementation with regards to SA_RESTART and POSIX compliant returns in the case where we deal with restartable signals. Currently we return EINTR everywhere which is mostly incorrect as the user can not know if she needs to recall the syscall or not. Return ECANCELED to signal that SA_RESTART was set and EINTR otherwise. Regression tests pass and so does the posixsuite. Timespec validation bits are needed to pass the later. OK mpi@, guenther@
* Implement MAP_STACK option for mmap(). Synchronous faults (pagefault andderaadt2018-04-122-4/+27
| | | | | | | | | | | | | | syscall) confirm the stack register points at MAP_STACK memory, otherwise SIGSEGV is delivered. sigaltstack() and pthread_attr_setstack() are modified to create a MAP_STACK sub-region which satisfies alignment requirements. Observe that MAP_STACK can only be set/cleared by mmap(), which zeroes the contents of the region -- there is no mprotect() equivalent operation, so there is no MAP_STACK-adding gadget. This opportunistic software-emulation of a stack protection bit makes stack-pivot operations during ROPchain fragile (kind of like removing a tool from the toolbox). original discussion with tedu, uvm work by stefan, testing by mortimer ok kettenis
* It is distasteful to have manual pages which don't refer to realderaadt2017-05-291-3/+3

| | | | | | | | | | | | correctly - logically complete that now by removing MLINKS from base; authors need only to ensure there is an entry in NAME for any function/ util being added.
