* Merge the sigaction() and sigprocmask() overloads/wrappers from libpthreadguenther2015-10-232-9/+9
| | | | | | | | | into libc, and move pthread_sigmask() as well (just a trivial wrapper). This provides consistent handling of SIGTHR between single- and multi-threaded programs and is a step in the merge of all the libpthread overloads, providing some ASM and Makefile bits that the other wrappers will need. ok deraadt@ millert@

* In the case where len is not a multiple of sizeof(RC4_CHUNK) the RC4 codejsing2015-10-212-126/+2
| | | | | | | | | | | | | | will end up doing a read and write of up to 7 bytes beyond the specified length. This is effectively a non-issue since we read and write back the same data and due to alignment it is within a page boundary. Regardless, avoid this by removing the "special" handling for the remaining length and allow the standard (non-chunk) code to process the remaining bytes, which does not result in overrun. Reported by Pascal Cuoq <cuoq at trust-in-soft.com> - thanks! ok beck@ miod@

| | | | | | | | | | | | The "authenticated encryption with additional data" API is used for ciphers like AES-GCM or ChaCha20-Poly1305. The manpage is a beginning and certainly needs more work, especially improvements in the EXAMPLES section. Based on agl's source code comments.
