* posix: Use posix_spawn for wordexpAdhemerval Zanella2019-10-091-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch replaces the fork+exec by posix_spawn on wordexp, which allows a better scability on Linux and simplifies the thread cancellation handling. The only change which can not be implemented with posix_spawn the /dev/null check to certify it is indeed the expected device. I am not sure how effetive this check is since /dev/null tampering means something very wrong with the system and this is the least of the issues. My view is the tests is really out of the place and the hardening provided is minimum. If the idea is still to provide such check, I think a possibilty would be to open /dev/null, check it, add a dup2 file action, and close the file descriptor. Checked on powerpc64le-linux-gnu and x86_64-linux-gnu. * include/spawn.h (__posix_spawn_file_actions_addopen): New prototype. * posix/spawn_faction_addopen.c (posix_spawn_file_actions_addopen): Add internal alias. * posix/wordexp.c (create_environment, free_environment): New functions. (exec_comm_child, exec_comm): Use posix_spawn instead of fork+exec. * posix/wordexp-test.c: Use libsupport.

* Remove the str(n)dup inlines from string/bits/string2.h. Although inliningWilco Dijkstra2017-03-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | calls with constant strings shows a small (~10%) performance gain, strdup is typically used in error reporting code, so not performance critical. Remove the now unused __need_malloc_and_calloc related defines from stdlib.h. Rename existing uses of str(n)dup to __str(n)dup so it no longer needs to be redirected to a builtin. Also building GLIBC with -Os now no longer shows localplt or linkname space failures (partial fix for BZ #15105 and BZ #19463).

| | | | | | | | POSIX requires that we make a copy, so we allocate a new string and free it in posix_spawn_file_actions_destroy. Reported by David Reid, Alex Gaynor, and Glyph Lefkowitz. This bug may have security implications.
