2019-09-06upstream: lots of things were relying on libcrypto headers todjm@openbsd.org
transitively include various system headers (mostly stdlib.h); include them explicitly OpenBSD-Commit-ID: 5b522f4f2d844f78bf1cc4f3f4cc392e177b2080
2019-07-05upstream: When system calls indicate an error they return -1, notderaadt@openbsd.org
some arbitrary value < 0. errno is only updated in this case. Change all (most?) callers of syscalls to follow this better, and let's see if this strictness helps us in the future. OpenBSD-Commit-ID: 48081f00db7518e3b712a49dca06efc2a5428075

2018-12-13Don't pass loginmsg by address now that it's an sshbuf*Kevin Adler
In 120a1ec74, loginmsg was changed from the legacy Buffer type to struct sshbuf*, but it missed changing calls to sys_auth_allowed_user and sys_auth_record_login which passed loginmsg by address. Now that it's a pointer, just pass it directly. This only affects AIX, unless there are out of tree users.

2017-09-12upstream commitdjm@openbsd.org
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

Validate address ranges for AllowUser/DenyUsers at configuration load time and refuse to accept bad ones.
