fix: pass correct dst address to outgoing PROXY protocol header 
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

feat: add mask_proxy_protocol option for PROXY protocol to mask_host 
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.

fix: resolve clippy warnings 
Reduce clippy warnings from54 to16 by fixing mechanical issues:

- collapsible_if: collapse nested if-let chains with let-chains
- clone_on_copy: remove unnecessary .clone() on Copy types
- manual_clamp: replace .max().min() with .clamp()
- unnecessary_cast: remove redundant type casts
- collapsible_else_if: flatten else-if chains
- contains_vs_iter_any: replace .iter().any() with .contains()
- unnecessary_closure: replace .or_else(|| x) with .or(x)
- useless_conversion: remove redundant .into() calls
- is_none_or: replace .map_or(true, ...) with .is_none_or(...)
- while_let_loop: convert loop with if-let-break to while-let

Remaining16 warnings are design-level issues (too_many_arguments,
await_holding_lock, type_complexity, new_ret_no_self) that require
architectural changes to fix.

fix: add #[cfg(test)] to unused ProxyError import 
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.

Vladislav Yaroslavlev 68c3abee6c
fix: eliminate all compiler warnings 
- 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.

Secure Payload length fixes 2026-02-23 02:38:25 +03:00
Alexey 6ff29e43d3
Middle-End protocol hardening 
- Secure framing / hot-path fix: enforced a single length + padding contract across the framing layer. Replaced legacy runtime `len % 4` recovery with strict validation to eliminate undefined behavior paths.

- ME RPC aligned with C reference contract: handshake now includes `flags + sender_pid + peer_pid`. Added negotiated CRC mode (CRC32 / CRC32C) and applied the negotiated mode consistently in read/write paths.

- Sequence fail-fast semantics: immediate connection termination on first sequence mismatch with dedicated counter increment.

- Keepalive reworked to RPC ping/pong: removed raw CBC keepalive frames. Introduced stale ping tracker with proper timeout accounting.

- Route/backpressure observability improvements: increased per-connection route queue to 4096. Added `RouteResult` with explicit failure reasons (NoConn, ChannelClosed, QueueFull) and per-reason counters.

- Direct-DC secure mode-gate relaxation: removed TLS/secure conflict in Direct-DC handshake path.

feat: add hostname support for SOCKS4/SOCKS5 upstream proxies 
Previously, SOCKS proxy addresses only accepted IP:port format.
Now both IP:port and hostname:port formats are supported.

Changes:
- Try parsing as SocketAddr first (IP:port) for backward compatibility
- Fall back to tokio::net::TcpStream::connect() for hostname resolution
- Log warning if interface binding is specified with hostname (not supported)

Example usage:
[[upstreams]]
type = "socks5"
address = "proxy.example.com:1080"
username = "user"
password = "pass"
