* sigreturn(2): Remove ancient compatibility warning about 4.2BSD.jilles2013-05-251-4/+0

* Make some tiny improvements to iconv_open().ed2013-05-251-21/+15
| | | | | | | | | - Remove an unneeded variable. - Fix whitespace bugs. - Fix typoes in comment. - Improve string handling a bit. Don't handroll strstr() and don't terminate a strdup()'ed string. Instead, simply strndup() the part we need.
* Only call free() on something we allocated.ed2013-05-251-2/+2
| | | | | | | If we were already provided a struct _citrus_iconv (e.g. through iconv_open_into()), we should not call free() in case io_init_context() fails. Instead, call it on the pointer of the allocated object, which will be NULL in case of iconv_open_into().
* Let iconv build on -HEAD properly.ed2013-05-233-0/+3
| | | | | | - Add NO_WMISSING_VARIABLE_DECLARATIONS where we use Yacc/Lex. - Add variable declarations where possible. - Add missing static keyword.

* Add <uchar.h>.ed2013-05-219-52/+410
| | | | | | | | | | | | The <uchar.h> header, part of C11, adds a small number of utility functions for 16/32-bit "universal" characters, which may or may not be UTF-16/32. As our wchar_t is already ISO 10646, simply add light-weight wrappers around wcrtomb() and mbrtowc(). While there, also add (non-yet-standard) _l functions, similar to the ones we already have for the other locale-dependent functions. Reviewed by: theraven

* popen(): Add 'e' mode character to set close-on-exec on the new fd.jilles2013-05-202-10/+27
| | | | | | | | | | | | | | If 'e' is used, the kernel must support the recently added pipe2() system call. The use of pipe2() with O_CLOEXEC also fixes race conditions between concurrent popen() calls from different threads, even if the close-on-exec flag on the fd of the returned FILE is later cleared (because popen() closes all file descriptors from earlier popen() calls in the child process). Therefore, this approach should be used in all cases when pipe2() can be assumed present. The old version of popen() rejects "re" and "we" but treats "r+e" like "r+".

* Add pipe2() system call.jilles2013-05-013-2/+46
| | | | | | | | | | | | | The pipe2() function is similar to pipe() but allows setting FD_CLOEXEC and O_NONBLOCK (on both sides) as part of the function. If p points to two writable ints, pipe2(p, 0) is equivalent to pipe(p). If the pointer is not valid, behaviour differs: pipe2() writes into the array from the kernel like socketpair() does, while pipe() writes into the array from an architecture-specific assembler wrapper.

* Add accept4() system call.jilles2013-05-013-3/+46
| | | | | | | | | | | | | | | The accept4() function, compared to accept(), allows setting the new file descriptor atomically close-on-exec and explicitly controlling the non-blocking status on the new socket. (Note that the latter point means that accept() is not equivalent to any form of accept4().) The linuxulator's accept4 implementation leaves a race window where the new file descriptor is not close-on-exec because it calls sys_accept(). This implementation leaves no such race window (by using falloc() flags). The linuxulator could be fixed and simplified by using the new code. Like accept(), accept4() is async-signal-safe, a cancellation point and permitted in capability mode.

* wordexp(): Remove wrong IFS usage.jilles2013-04-011-4/+1
| | | | | | | | | | | Words in shell script are separated by spaces or tabs independent of the value of IFS. The value of IFS is only relevant for the result of substitutions. Therefore, there should be a space between 'wordexp' and the words to be expanded, not an IFS character. Paranoia might dictate that the shell ignore IFS from the environment (even though our sh currently uses it), so do not depend on it in the new test case.
