When system calls indicate an error they return -1, not some arbitrary

value < 0. errno is only updated in this case. Change all (most?) callers of syscalls to follow this better, and let's see if this strictness helps us in the future.

environ and __progname are not declared in a public header; declare them

Merge the sigaction() and sigprocmask() overloads/wrappers from libpthread

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@

Pull in namespace.h when building all .c files using gcc's -include option,

2015-09-10T18:13:46Z

so that we can provide asm labels for the memcpy/memset/__stack_smash_handler calls that it generates ab initio. Eliminate direct #includes of it. Make sure it's a dependency of all objects (unnecessary for asm, but close enough). ok deraadt@

_NSIG is the number of valid signals including signal 0, so it's not a valid

signal number itself. Attempting to reset the signal action for it causes posix_spawn to fail, making the POSIX_SPAWN_SETSIGDEF flag unusable. ok guenther@

Fix previous commit: fd wasn't set in the FAE_DUP2 case

Add additional userland interfaces for setting close-on-exec on fds

2014-08-31T02:21:18Z

when creating them: mkostemp(), mkostemps(), the 'e' mode letter for fopen(), freopen(), fdopen(), and popen(). The close-on-exec flag will be cleared by the action created by posix_spawn_file_actions_adddup2(). Also, add support for the C11 'x' mode letter for fopen() and freopen(), setting O_EXCL when possibly creating files. Note: this requires kernel support for pipe2() and dup3()! ok millert@
