* Consolidate non cancellable close callAdhemerval Zanella2017-08-181-3/+3

* posix: Fix default posix_spawn return valueAdhemerval Zanella2017-07-051-20/+20
| | | | | | | | | | | | This patch fix the return value for error conditions for default posix_spawn (where the errno is expected). It also avoid clobber errno on fork call.

* posix: Improve default posix_spawn implementationAdhemerval Zanella2017-06-291-183/+179
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch improves the default posix implementation of posix_spawn{p} and align with Linux one. The main idea is to fix some issues already fixed in Linux code, and deprecated vfork internal usage (source of various bug reports). In a short: - It moves POSIX_SPAWN_USEVFORK usage and sets it a no-op. Since the process that actually spawn the new process do not share memory with parent (with vfork), it fixes BZ#14750 for this implementation. - It uses a pipe to correctly obtain the return upon failure of execution (BZ#18433). - It correctly enable/disable asynchronous cancellation (checked on ptl/tst-exec5.c). - It correctly disable/enable signal handling. Using this version instead of Linux shows only one regression, posix/tst-spawn3, because of pipe2 usage which increase total number of file descriptor. * sysdeps/posix/spawni.c (__spawni_child): New function. (__spawni): Rename to __spawnix.

* Fix posix_spawn getrlimit64 namespace (bug 17991).Joseph Myers2015-02-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | posix_spawn (a standard POSIX function) brings in a use of getrlimit64 (not a standard POSIX function). This patch fixes this by using __getrlimit64 and making getrlimit64 a weak alias. This is more complicated than some such changes because of files that define getrlimit64 in their own way using symbol versioning after including the main sysdeps/unix/sysv/linux/getrlimit64.c with a getrlimit macro defined. There are various existing patterns for such cases in glibc; the one I've used here is that a getrlimit64 macro disables the weak_alias / libc_hidden_weak calls, leaving it to the including file to define the getrlimit64 name in whatever way is appropriate. Tested for x86_64 and x86 that installed stripped shared libraries are unchanged by this patch. [BZ #17991] * include/sys/resource.h (__getrlimit64): Declare. Use libc_hidden_proto. * resource/getrlimit64.c (getrlimit64): Rename to __getrlimit64 and define as weak alias of __getrlimit64.
