* Returns EBUSY if dup2(2) is called for a LARVAL file.mpi2018-05-281-2/+6
| | | | | | | | | | | This prevents a panic due to a double free if a program exits after having called accept(2) and dup2(2) on the same fd but without the corresponding connect(5). It will also allows us to simplify file descriptor locking. The error code has been choosed to match Linux's behavior. Pointed by Mathieu on tech@ after a discussion with guenther@. ok visa@

* Validate timespec and return ECANCELED when interrupted with SA_RESTART.pirofti2018-04-242-6/+16
| | | | | | | | | | | | | | | 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@

* Fix three bugs in setlocale(3):schwarze2018-03-291-5/+7
| | | | | | | | | | | 1. setlocale(LC_ALL, "A"); setlocale(LC_CTYPE, "T"); setlocale(LC_ALL, NULL); must return "A/T/A/A/A/A", not "A". Fix this by always initializing the LC_ALL entry of newgl to "" in dupgl(). Reported by Karl Williamson <public at khwilliamson dot com> on bugs@, thanks! 2. Do not leak newgl when strdup(3) fails in setlocale(3). 3. For setlocale(LC_ALL, "C/C/fr_FR.UTF-8/C/C/C"); correctly set _GlobalRuneLocale; i found 2. and 3. while looking at the code. Feedback on a buggy earlier version and OK martijn@.
