/dev/urandom. Does well in the fallback case. Get it in tree so it can be worked on. ok otto@ deraadt@
2014-06-20Remove OPENSSL_instrument_halt and OPENSSL_far_spin, which both mightmiod2-140/+0
have been used under DJGPP in the previous century (if at all).
2014-06-20Fix incorrect bounds check in amd64 assembly version of bn_mul_mont();miod4-8/+8
noticed and fix by Fedor Indutny of Joyent ( https://github.com/joyent/node/issues/7704 )
2014-06-20Simple regress test for the amd64 bn_mul_mont bug found by Joyentmiod3-2/+86
( https://github.com/joyent/node/issues/7704 ), about to be fixed in libcrypto.

it getting siblings.
2014-06-20arc4random: hard fail with raise(SIGKILL) if getentropy() returns -1matthew1-3/+4
Allow other non-zero return values in case we change our mind to return an ssize_t byte count instead of simple success/fail. ok deraadt, djm
2014-06-19convert CRYPTO_memcmp to timingsafe_memcmp based on current policy favoringtedu18-44/+44
libc interfaces over libcrypto interfaces. for now we also prefer timingsafe_memcmp over timingsafe_bcmp, even when the latter is acceptable. ok beck deraadt matthew miod
2014-06-19check stack push return and make some effort to clean up. ok beck miodtedu2-4/+12
2014-06-19improve error checking. set error code on error, and check malloc return.tedu2-4/+26
add missing unlock in one case. ok lteo miod
2014-06-19Move rs_chacha and rs_buf into the same memory page and don't mark itmatthew1-22/+31
MAP_INHERIT_ZERO anymore. This restores arc4random's previous behavior where fork children would mix in some randomness from the parent process. New behavior noticed by deraadt ok deraadt, tedu
2014-06-18Always call atexit handlers as if they were registered with __cxa_atexit.kettenis3-19/+13
The extra argument doesn't hurt genuine atexit handlers and this fixes a bug where we didn't provide the argument (effectively passing garbage) for functions registered with __cxa_atexit in the main executable. Pointed out by Dmitriy Ivanov <dimitry@google.com> and Elliott Hughes <enh@google.com>. ok matthew@
2014-06-18Add regress tests to make sure arc4random(3) is reinitializedmatthew3-2/+181
correctly in fork children.

2014-06-17ssl_session_cmp is not a sort function, can use CRYPTO_memcmp here too.tedu2-4/+8
2014-06-17Use MAP_INHERIT_ZERO in arc4random(3)matthew1-37/+44
Now instead of calling getpid() each time a user invokes arc4random(), we're able to rely on the kernel zero'ing out the RNG state if the process forks. ok deraadt, djm
2014-06-15free iv, then cleanse. from Cyril Jouvetedu2-4/+4
2014-06-15Simplify EVP_MD_CTX_create() by just using calloc(). Also, use 0 ratherjsing2-18/+8
than '\0' for several memset(). ok beck@ miod@
2014-06-15Simplify EVP_CIPHER_CTX_new() - stop pretending that EVP_CIPHER_CTX_init()jsing2-12/+4
does something special... just use calloc() instead. ok beck@ miod@
2014-06-15Add missing OPENSSL_cleanse() in aead_aes_gcm_cleanup().jsing2-2/+4
ok beck@ miod@
2014-06-15The OPENSSL_cleanse() in aes_gcm_cleanup() only cleans the gcm field of thejsing2-4/+4
EVP_AES_GCM_CTX, leaving the AES key untouched - clean the entire context, rather than just part of it. ok beck@ miod@
2014-06-15Rename ssl3_record_sequence_update() to ssl3_record_sequence_increment(),jsing7-55/+28
so that it reflects what it is actually doing. Use this function in a number of places that still have the hand rolled version. ok beck@ miod@

2014-06-15In srandomdev(), use arc4random_buf() instead of from the kernel.deraadt1-4/+3

2014-06-14Add more bounded attributes to the buffer and md5/sha headers in libsslavsm6-38/+70

2014-06-13For now... assume success of getentropy() just like we assumed successderaadt1-3/+3
of sysctl(). Mark it with XXX while we consider.
2014-06-13Correctly calculate the key block length when using export ciphers.jsing2-2/+10
2014-06-13Overhaul the keyblock handling in ssl3_change_cipher_state(). Usejsing1-32/+45
meaningful variable names with use with pointer arithmitic rather than complex array indexing.
2014-06-13Correctly calculate the key block length when used with export ciphers.jsing1-17/+24
While here, use meaningful variable names and simplify the calculation.
2014-06-13Remove deprecated RFC2292 ancillary data convenience functions.chrisz2-488/+2
They are obsoleted by the RFC3542 api. ok mpi@
2014-06-13use getgentropy() call. If it fails, things are pretty bad --deraadt1-8/+3
call abort(). this direction discussed at length with miod beck tedu matthew etc
2014-06-13use getentropy; from matthewderaadt1-5/+2
2014-06-13Use meaningful variable names, rather than i, j, k and cl.jsing1-23/+27
2014-06-13Do not bother trying to work out of we can reuse a cipher context - justjsing1-22/+12
throw it away and create a new one. This simplifies the code and also allows ASR to do its thing.
2014-06-13Separate the comression handling from the cipher/message digest handling injsing1-43/+47
ssl3_change_cipher_state().
2014-06-13Swap compress/expand around so they are in the correct order - these endedjsing2-28/+28
up in the wrong order when the code was refactored.
2014-06-13The export_key/export_iv variables are only used in the is_export case.jsing1-7/+10
Also use c rather than &c[0].
2014-06-13Rename a bunch of variables in ssl3_change_cipher_state() for readability.jsing1-38/+40
This also brings it inline with tls1_change_cipher_state_cipher().
2014-06-13Add ChaCha20-Poly1305 based ciphersuites.jsing10-14/+162
Based on Adam Langley's chromium patches. Tested by and ok sthen@
