refactor channels.c Move static state to a "struct ssh_channels" that is allocated at runtime and tracked as a member of struct ssh. Explicitly pass "struct ssh" to all channels functions. Replace use of the legacy packet APIs in channels.c. Rework sshd_config PermitOpen handling: previously the configuration parser would call directly into the channels layer. After the refactor this is not possible, as the channels structures are allocated at connection time and aren't available when the configuration is parsed. The server config parser now tracks PermitOpen itself and explicitly configures the channels code later. ok markus@ Upstream-ID: 11828f161656b965cc306576422613614bea2d8f

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.

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.
