* Add additional userland interfaces for setting close-on-exec on fdsguenther2014-08-317-63/+231
| | | | | | | | | | | | | 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@

| | | | | | | arc4random_buf() to avoid lots of arc4random() calls with a getpid() syscall for each one. We fetch 32 bytes of random data at a time which can handle up to 16 Xs. 16 Xs should be enough for anyone. Requested and OK deraadt@

* Use nl_langinfo(RADIXCHAR) instead of localeconv()->decimal_point inmatthew2012-06-262-4/+10
| | | | | | | | | | | | | | | | printf() and avoid calling it unless needed (i.e., when we have a floating point value to print). This isn't a big concern currently due to our limited locale support and current localeconv() implementation, but it's still technically a data race and implementing POSIX 2008 per-thread locales is likely to make it worse. nl_langinfo() isn't guaranteed by POSIX to be thread-safe either, but at least our current implementation is thread-safe and it's a simpler interface to keep that way. Printing floating point values isn't async-signal-safe anyway due to gdtoa()'s use of malloc(), so that's not an issue. ok deraadt, stsp, millert
