If a program loads a DSO (dlopen) that sets up a pthread_atfork handler(s), and then subsequently closes the DSO, the handler(s) are left in place. If fork() is subsequently called, the handlers are invoked even though the DSO has been removed causing crashes or unpredictable code execution. This is because the code in __cxa_finalize(atexit.c)to invoke the unregister_atfork() routine is ifdef'd out with the comment that it hasn't been "looked into this yet...".

In addition to the common getopt interface, it provides automatic response to `--help' and `--version' options and use of custom parser in conjunction with argp native option parser, among others. Argp support is required by elfutils package and prelink. In uClibc argp functionalities has been moved from C library to libuargp.so Further the libc.so linker script contains an AS_NEEDED entry so that it doesn't need to link libuargp.so explicitely. Disable argp test if feature disabled.

Syscall will always return EINVAL. We must use __kernel_* types and __SYSCALL_SIGSET_T_SIZE. * It have excess checks for NSEC_PER_SEC. Original code from select() implementation has struct timeval => struct timespec conversion, kernel select() syscall implementation do the same. But none of libc versions (glibc, eglibc, musl) I know, perform similar checks for pselect() - there is no structure fields conversions, just struct timespec through all the calls. To have such checks in uClibc-ng we need one example, at least. * It is possible to avoid extra userspace reads from kernel code if sigmask == NULL. I suggest to do it, for a few bytes cost. * Commit didn't add test case to testsuite.
