2016-09-29Remove portability support for mmapDamien Miller
We no longer need to wrap/replace mmap for portability now that pre-auth compression has been removed from OpenSSH.
2016-09-29upstream commitdjm@openbsd.org
Remove support for pre-authentication compression. Doing compression early in the protocol probably seemed reasonable in the 1990s, but today it's clearly a bad idea in terms of both cryptography (cf. multiple compression oracle attacks in TLS) and attack surface. Moreover, to support it across privilege-separation zlib needed the assistance of a complex shared-memory manager that made the required attack surface considerably larger. Prompted by Guido Vranken pointing out a compiler-elided security check in the shared memory manager found by Stack (http://css.csail.mit.edu/stack/); ok deraadt@ markus@ NB. pre-auth authentication has been disabled by default in sshd for >10 years.

Avoid a theoretical signed integer overflow should BN_num_bytes() ever violate its manpage and return a negative value. Improve order of tests to avoid confusing increasingly pedantic compilers.

remove 3des-cbc from the client's default proposal; 64-bit block ciphers are not safe in 2016 and we don't want to wait until attacks like sweet32 are extended to SSH. As 3des-cbc was the only mandatory cipher in the SSH RFCs, this may cause problems connecting to older devices using the defaults, but it's highly likely that such devices already need explicit configuration for KEX and hostkeys anyway. ok deraadt, markus, dtucker Upstream-ID: a505dfe65c6733af0f751b64cbc4bb7e0761bc2f
