* using reallocarray() gives us multiplicative integer overflow checkingderaadt2014-10-081-3/+3
| | | | | | | | | | in case something wants to create massive amounts of environment, like a bit more than 1/4 of a 32-bit address space. unrealistic -- but why audit one code path, and not treat others the same? then you have to re-engage everytime you see the code. read the news, that isn't what developers do. At least if the code paths look the same, there is hope, because they are easier to verify for correctness. developers need to give other developers a chance to want to care.

| | | | | | | | | | | | | X509_PURPOSE object (obtained with X509_PURPOSE_get0() instead of being allocated in the function) to be freed if modifying that object would fail due to a low memory condition, while this object would still be referenced elsewhere. Fix this by only cleaning the object if we did not allocate it here. While there, fail early if either `name' or `sname' are NULL, rather than allocating an object and realizing we have nothing to strdup() into it. ok guenther@

* Add support for automatic ephemeral EC keys.jsing2014-10-0314-26/+152
| | | | | | | | | | This allows an SSL server to enable ECDHE ciphers with a single setting, which results in an EC key being generated using the first preference shared curve. Based on OpenSSL with inspiration from boringssl. ok miod@

* openssl.cnf tweaks following recent changes to usr.bin/openssl:sthen2014-10-011-44/+3
| | | | | | | | | | | | | | - don't define default_bits, allowing the compiled-in default (now 2048 bits) to take priority. - add commented-out default_md line in case somebody needs an easy way to change this. - remove some sample sections which aren't really useful in the default file (/etc/examples is the place for a more descriptive config, this file should be barebones). Help/OK jsing@. OKs on earlier diff (openssl.cnf only) from phessler@ aja@.

| | | | | | | | | | keys by default (instead of SHA1/3DES) and update documentation to match. Another way to do this is s/NID_sha1/NID_sha256/ in src/crypto/rsa/rsa_ameth.c ("case ASN1_PKEY_CTRL_DEFAULT_MD_NID") but going with the more targetted method above that only affects "openssl req" for now. Help/OK jsing@. OKs on earlier diffs changing openssl.cnf from phessler@ aja@
* Clean up EC cipher handling in ssl3_choose_cipher().jsing2014-09-306-290/+304
| | | | | | | | | | | The existing code reaches around into various internals of EC, which it should not know anything about. Replace this with a set of functions that that can correctly extract the necessary details and handle the comparisions. Based on a commit to OpenSSL, with some inspiration from boringssl. ok miod@
