* Add EVP_AEAD_CTX_init(3) manpage to document the new(ish) AEAD API.reyk2015-10-144-1/+285
| | | | | | | | | | | | 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.

| | | | | | | | error was present in the original 2004 commit, so it hasn't been used in over 11 years, thus exceeding our deprecation requirements by over a decade. OpenSSL has chosen to *fix it*; we'll gladly watch it burn ok jsing@

* Initial support for pledges in openssl(1) commands.doug2015-10-1047-46/+281
| | | | | | | | | | | | | | | | openssl(1) has two mechanisms for operating: either a single execution of one command (looking at argv[0] or argv[1]) or as an interactive session than may execute any number of commands. We already have a top level pledge that should cover all commands and that's what interactive mode must continue using. However, we can tighten up the pledges when only executing one command. This is an initial stab at support and may contain regressions. Most commands only need "stdio rpath wpath cpath". The pledges could be further restricted by evaluating the situation after parsing options. deraadt@ and beck@ are roughly fine with this approach.
* normalize the ordering of tame requests (particularily, "rpath wpath cpath",deraadt2015-10-101-2/+2
| | | | | | | which i have put in that order). this is not important, but helps look for outliers which might be strange. it hints that "ioctl" should be reassessed in a few places, to see if "tty" is better; that "unix" may be used in some places where "route" could now work.

* SSL_new(): fix ref counting and memory leak in error path.doug2015-10-032-16/+6
| | | | | | | | | | Rather than a half-hearted attempt to free up resources and fix ref counting at the SSL_CTX level, let SSL_free() do its job. This diff got lost in the shuffle somewhere. It's from last year. Ref counting error reported by Parakleta in github ticket #51. Thanks! ok jsing@, beck@
