* upstream: Remove unused compat.h includes.dtucker@openbsd.org2023-03-051-2/+1
| | | | | | | | We've previously removed a lot of the really old compatibility code, and with it went the need to include compat.h in most of the files that have it. OpenBSD-Commit-ID: 5af8baa194be00a3092d17598e88a5b29f7ea2b4
* upstream: Add server debugging for hostbased auth.dtucker@openbsd.org2022-12-091-6/+5
| | | | | | | | auth_debug_add queues messages about the auth process which is sent to the client after successful authentication. This also sends those to the server debug log to aid in debugging. From bz#3507, ok djm@ OpenBSD-Commit-ID: 46ff67518cccf9caf47e06393e2a121ee5aa258a

| | | | Reduces diff vs OpenBSD by a small amount.
* auth_log: dont log partial successes as failuresVincent Brillault2021-06-041-13/+16
| | | | | | | | By design, 'partial' logins are successful logins, so initially with authenticated set to 1, for which another authentication is required. As a result, authenticated is always reset to 0 when partial is set to 1. However, even if authenticated is 0, those are not failed login attempts, similarly to attempts with authctxt->postponed set to 1.

* prefer login_getpwclass() to login_getclass()Damien Miller2021-02-181-1/+1
| | | | | | | | FreeBSD has login_getpwclass() that does some special magic for UID=0. Prefer this to login_getclass() as its easier to emulate the former with the latter. Based on FreeBSD PR 37416 via Ed Maste; ok dtucker@

* upstream: load_hostkeys()/hostkeys_foreach() variants for FILE*djm@openbsd.org2020-12-211-3/+3
| | | | | | | | | | | | | | | | | Add load_hostkeys_file() and hostkeys_foreach_file() that accept a FILE* argument instead of opening the file directly. Original load_hostkeys() and hostkeys_foreach() are implemented using these new interfaces. Add a u_int note field to the hostkey_entry and hostkey_foreach_line structs that is passed directly from the load_hostkeys() and hostkeys_foreach() call. This is a lightweight way to annotate results between different invocations of load_hostkeys(). ok markus@ OpenBSD-Commit-ID: 6ff6db13ec9ee4edfa658b2c38baad0f505d8c20

* upstream: support for requiring user verified FIDO keys in sshddjm@openbsd.org2020-08-271-4/+5
| | | | | | | | | | | | | This adds a "verify-required" authorized_keys flag and a corresponding sshd_config option that tells sshd to require that FIDO keys verify the user identity before completing the signing/authentication attempt. Whether or not user verification was performed is already baked into the signature made on the FIDO token, so this is just plumbing that flag through and adding ways to require it. feedback and ok markus@ OpenBSD-Commit-ID: 3a2313aae153e043d57763d766bb6d55c4e276e6

* Don't pass loginmsg by address now that it's an sshbuf*Kevin Adler2018-12-131-2/+2
| | | | | | | | | 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.

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
