- Per-user ad_tag in [access.user_ad_tags], global fallback in general.ad_tag
- User tag overrides global; if no user tag, general.ad_tag is used
- Both general.ad_tag and user_ad_tags support hot-reload (no restart)
When mask_unix_sock is configured, mask_proxy_protocol was silently
ignored and no PROXY protocol header was sent to the backend. Apply
the same header-building logic as the TCP path in both masking relay
and TLS fetcher (raw and rustls).
Previously handle_bad_client used stream.local_addr() (the ephemeral
socket to the mask backend) as the dst in the outgoing PROXY protocol
header. This is wrong: the dst should be the address telemt is listening
on, or the dst from the incoming PROXY protocol header if one was present.
- handle_bad_client now receives local_addr from the caller
- handle_client_stream resolves local_addr from PROXY protocol info.dst_addr
or falls back to a synthetic address based on config.server.port
- RunningClientHandler.do_handshake resolves local_addr from stream.local_addr()
overridden by PROXY protocol info.dst_addr when present, and passes it
down to handle_tls_client / handle_direct_client
- masking.rs uses the caller-supplied local_addr directly, eliminating the
stream.local_addr() call
Adds mask_proxy_protocol config option (0 = off, 1 = v1 text, 2 = v2 binary)
that sends a PROXY protocol header when connecting to mask_host. This lets
the backend see the real client IP address.
Particularly useful when the masking site (nginx/HAProxy) runs on the same
host as telemt and listens on a local port — without this, the backend loses
the original client IP entirely.
PROXY protocol header is also sent during TLS emulation fetches so that
backends with proxy_protocol required don't reject the connection.
The ProxyError import in tls.rs is only used in test code
(validate_server_hello_structure function), so guard it with
#[cfg(test)] to eliminate the unused import warning.
- Add ProxyError import and fix Result type annotation in tls.rs
- Add Arc import in stats/mod.rs test module
- Add BodyExt import in metrics.rs test module
These imports were missing causing compilation failures in
cargo test --release with 10 errors.
- Remove unused imports across multiple modules
- Add #![allow(dead_code)] for public API items preserved for future use
- Add #![allow(deprecated)] for rand::Rng::gen_range usage
- Add #![allow(unused_assignments)] in main.rs
- Add #![allow(unreachable_code)] in network/stun.rs
- Prefix unused variables with underscore (_ip_tracker, _prefer_ipv6)
- Fix unused_must_use warning in tls_front/cache.rs
This ensures clean compilation without warnings while preserving
public API items that may be used in the future.
