Mark the sshd_config UsePrivilegeSeparation option as deprecated, effectively making privsep mandatory in sandboxing mode. ok markus@ deraadt@ (note: this doesn't remove the !privsep code paths, though that will happen eventually). Upstream-ID: b4c52666256c4dd865f8ce9431af5d6ce2d74a0a

sshd_config is documented to set GSSAPIStrictAcceptorCheck=yes by default, so actually make it do this. bz#2637 ok dtucker Upstream-ID: 99ef8ac51f17f0f7aec166cb2e34228d4d72a665

Add a sshd_config DisableForwaring option that disables X11, agent, TCP, tunnel and Unix domain socket forwarding, as well as anything else we might implement in the future. This, like the 'restrict' authorized_keys flag, is intended to be a simple and future-proof way of restricting an account. Suggested as a complement to 'restrict' by Jann Horn; ok markus@ Upstream-ID: 203803f66e533a474086b38a59ceb4cf2410fcf7

Validate address ranges for AllowUser/DenyUsers at configuration load time and refuse to accept bad ones. It was previously possible to specify invalid CIDR address ranges (e.g. djm@127.1.2.3/55) and these would always match. Thanks to Laurence Parry for a detailed bug report. ok markus (for a previous diff version) Upstream-ID: 9dfcdd9672b06e65233ea4434c38226680d40bfb

restore pre-auth compression support in the client -- the previous commit was intended to remove it from the server only. remove a few server-side pre-auth compression bits that escaped adjust wording of Compression directive in sshd_config(5) pointed out by naddy@ ok markus@ Upstream-ID: d23696ed72a228dacd4839dd9f2dec424ba2016b
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.
