* mod_saslauth: Fire event per SASL stepMatthew Wild2023-12-051-2/+5
| | | | | This matches the behaviour of the newer mod_sasl2 implementation. It allows plugins to observe (and potentially, with caution, modify) the SASL exchange.
* mod_saslauth: Fire event at start of authentication attemptKim Alvefur2023-12-011-0/+6
| | | | | | As extension point for rate limiting and similar checks, so they can hook a single event instead of <{sasl1}auth> or stream features, which might not be fired in case of SASL2 or e.g. HTTP based login.

* mod_saslauth: Clear 'auto' from endpoint hash var, it's not a real hash ↵Matthew Wild2023-10-261-0/+1
| | | | (thanks tmolitor)
* mod_saslauth, mod_c2s: Disable tls-server-end-point channel binding by defaultMatthew Wild2023-10-261-7/+23
| | | | | | | | | | | | | | | | | | | | | | This channel binding method is now enabled when a hash is manually set in the config, or it attempts to discover the hash automatically if the value is the special string "auto". A related change to mod_c2s prevents complicated certificate lookups in the client connection hot path - this work now happens only when this channel binding method is used. I'm not aware of anything else that uses ssl_cfg (vs ssl_ctx). Rationale for disabling by default: - Minor performance impact in automatic cert detection - This method is weak against a leaked/stolen private key (other methods such as 'tls-exporter' would not be compromised in such a case) Rationale for keeping the implementation: - For some deployments, this may be the only method available (e.g. due to TLS offloading in another process/server).

* mod_saslauth: Get correct 'tls-server-end-point' with new LuaSec APIKim Alvefur2022-10-231-12/+15
| | | | | | MattJ contributed new APIs for retrieving the actually used certificate and chain to LuaSec, which are not in a release at the time of this commit.
* mod_saslauth: Derive hash from certificate per tls-server-end-pointKim Alvefur2021-06-291-0/+34
| | | | | | | | | | | This originally used a WIP implementation of cert:sigalg(), a method to retrieve certificate signature algorithm, but it was never submitted upstream. https://github.com/Zash/luasec/tree/zash/sigalg cert:getsignaturename() was merged in https://github.com/brunoos/luasec/commit/de393417b7c7566caf1e0a0ad54132942ac4f049 XEP-0440 v0.3.0 made implementing tls-server-end-point a MUST
* mod_saslauth: Support tls-server-end-point via manually specified hashKim Alvefur2020-12-071-0/+13
| | | | | | | | Since this channel binding method is said to enable TLS offloading then you need tell Prosody the hash (or the full cert), so this seems like a good start. Support is RECOMMENDED in XEP-0440 version 0.2

* mod_saslauth: Only announce bind feature if no resource yet boundMatthew Wild2022-09-031-1/+1
| | | | It's now possible to bind during SASL2 negotiation.
* mod_saslauth: Rename field from 'scope'->'role'Matthew Wild2022-06-151-1/+1
| | | | | | | The 'scope' term derives from OAuth, and represents a bundle of permissions. We're now setting on the term 'role' for a bundle of permissions. This change does not affect any public modules I'm aware of.
* mod_saslauth: Implement RFC 9266 'tls-exporter' channel binding (#1760)Kim Alvefur2022-06-011-0/+15
| | | | | | | | | | | | | Brings back SCRAM-SHA-*-PLUS from its hiatus brought on by the earlier channel binding method being undefined for TLS 1.3, and the increasing deployment of TLS 1.3. See 1bfd238e05ad and #1542 Requires future version of LuaSec, once support for this key material export method is merged. See https://github.com/brunoos/luasec/pull/187
* mod_saslauth: Advertise channel bindings via XEP-0440Kim Alvefur2020-12-061-0/+10
| | | | | This is useful when there's more than one channel binding in circulation, since perhaps there will be varying support for them.
* net: isolate LuaSec-specificsJonas Schäfer2022-04-271-6/+5
| | | | | | | | | | | | | | For this, various accessor functions are now provided directly on the sockets, which reach down into the LuaSec implementation to obtain the information. While this may seem of little gain at first, it hides the implementation detail of the LuaSec+LuaSocket combination that the actual socket and the TLS layer are separate objects. The net gain here is that an alternative implementation does not have to emulate that specific implementation detail and "only" has to expose LuaSec-compatible data structures on the new functions.
* usermanager, mod_saslauth: Default to internal_hashed if no auth module ↵Matthew Wild2022-02-101-1/+1
| | | | | | | | | | specified The default config was updated in this way long ago, but if no option was present in the config, Prosody would load internal_plain. This change can result in changes (for the better) for people using very old configuration files lacking an 'authentication' setting.
* various: Require encryption by default for realKim Alvefur2021-12-251-1/+1
| | | | | | | | | These options have been specified (and enabled) in the default config file for a long time. However if unspecified in the config, they were not enabled. Now they are. This may result in a change of behaviour for people using very old config files that lack the require_encryption options. But that's what we want.

| | | | | | | | | | | | | | | | The 'tls-unique' channel binding is undefined in TLS 1.3 according to a single sentence in parenthesis in Apendix C of RFC 8446 This may trigger downgrade protection in clients that were expecting channel binding to be available.
