If that happens in EVP_CipherInit_ex/EVP_CIPHER_CTX_copy set cipher = NULL,
aes_gcm_cleanup should check that gctx != NULL before calling OPENSSL_cleanse.

The core SipHash supports either 8 or 16-byte output and a configurable
number of rounds.
The default behavior, as added to EVP, is to use 16-byte output and
2,4 rounds, which matches the behavior of most implementations.
There is an EVP_PKEY_CTRL that can control the output size.

Originally a crash in 32-bit build was reported CHACHA20-POLY1305
cipher. The crash is triggered by truncated packet and is result
of excessive hashing to the edge of accessible memory. Since hash
operation is read-only it is not considered to be exploitable
beyond a DoS condition. Other ciphers were hardened.
Thanks to Robert Święcki for report.

This function is used to validate application supplied parameters. An

When doing in place encryption the overlapping buffer check can fail
incorrectly where we have done a partial block "Update" operation. This
fixes things to take account of any pending partial blocks.

If we have previously been passed a partial block in an "Update" call then
make sure we properly increment the output buffer when we use it.

CLA: trivial
The definition of STITCHED_CALL relies on OPENSSL_NO_ASM. However,
when a configuration simply lacks the assembler implementation for RC4
(which is where we have implemented the stitched call), OPENSSL_NO_ASM
isn't implemented. Better, then, to rely on specific macros that
indicated that RC4 (and MD5) are implemented in assembler.
For this to work properly, we must also make sure Configure adds the
definition of RC4_ASM among the C flags.
