- Return errors from MasqueConn.Read/Write instead of silently
succeeding (prevents infinite busy-loops and silent data loss
if these methods are accidentally called).
- Set recorder Network field in protocol dispatch switch rather
than hardcoding "udp", so early errors don't misreport type.
- Clarify that DatagramConn context-ID handling only supports
context ID 0 (sufficient for CONNECT-UDP per RFC 9298).
Merge beezly/fix/configurable-pipe-timeout with conflict resolution
in pipe.go (PipeOption/WithReadTimeout functional options pattern).
Fix pipe_test.go: update 4 pipeHalf() calls to pass readTimeout arg
matching the new signature.
Fix setMark early-return conditions that were inverted relative to
Linux: on FreeBSD (SO_USER_COOKIE) and OpenBSD (SO_RTABLE), a
non-zero mark was short-circuited instead of applied, disabling
socket marking entirely.
Also fix GetClientIP to trim leading whitespace from X-Forwarded-For
entries (per RFC 7239), and fix Body.Read to subtract len(b) instead
of n from recordSize when a single read exceeds the remaining quota.
Add unit tests for internal/net/ (addr, dialer, http, ip, net, pipe,
transport, resolve, proxyproto, udp).
Pipe: remove context.WithCancel that caused premature ctx.Done()
before the second pipeHalf could return its error. Replace with a
completed counter that drains both errors even on cancellation.
Transport: increase error channel buffer from 1 to 2 to prevent
goroutine leak when both CopyBuffer goroutines complete.
Add configurable TCP keepalive (keepalive, keepalive.idle,
keepalive.interval, keepalive.count) to all TCP-based transport types:
tls, mtls, mtcp, ws/wss, mws/mwss, http2, ssh, sshd listeners and
tls, mtls, mtcp, ws/wss, mws/mwss, ssh, sshd dialers.
For types that already use "keepalive" for an app-level protocol
(grpc listener/dialer, ws/mws dialers, ssh/sshd dialers), the TCP
keepalive parameters are exposed under the tcp.keepalive.* prefix to
avoid ambiguity.
Also extract shared helpers into internal/net/keepalive.go:
- WrapKeepaliveListener: applies KeepAliveConfig on every accepted TCPConn
- ApplyKeepalive: applies KeepAliveConfig to a single TCPConn

The 30s hardcoded readTimeout in Pipe() caused all CONNECT tunnel
connections to be hard-closed after 30s of inactivity, breaking
WebSocket and long-polling connections through the proxy.
Pipe() now accepts a WithReadTimeout(d) option. When d is 0 (the
default) no read deadline is set, relying on TCP keepalives or context
cancellation to detect dead connections instead.
The HTTP handler exposes this as the idleTimeout metadata key.
Fixes: https://github.com/go-gost/x/issues/91
- Add Header field to PHT Client and clientConn structs
- Support custom headers in authorize, push, and pull requests
- Add metadata parsing for header configuration as map[string]string
- Enables PHT usage with header-based authentication (e.g., Cloudflare Access)
Backwards compatible - headers are optional.
Implement UDP tunneling over HTTP/3 using HTTP Datagrams (RFC 9297):
- Add masque handler for server-side CONNECT-UDP
- Add masque connector and h3-masque dialer for client-side
- Add enableDatagrams option to HTTP/3 listener
- Add shared utilities for datagram connections and path parsing
Resource management and connection caching:
- Add deferred stream cleanup in connector on error paths
- Add IsClosed() and Close() methods to Client for proper session management
- Clean up stale cached clients in dialer before reuse
- Close underlying stream when DatagramConn is closed
- Move RequestStream opening from connector to dialer to enable dead
connection detection and cache invalidation (follows QUIC dialer pattern)
Extend MASQUE implementation to support TCP tunneling via standard HTTP/3
CONNECT method, in addition to existing UDP support via CONNECT-UDP:
- Add StreamConn type for TCP data transfer over HTTP/3 stream body
- Update handler to dispatch based on :protocol pseudo-header:
- "connect-udp" for UDP (RFC 9298)
- Empty/"HTTP/3.0" for TCP (RFC 9114)
- Add handleConnectTCP() using bidirectional stream relay
- Update connector to support both TCP and UDP networks
- Add connectTCP() for standard CONNECT requests
TCP uses :authority for target address and stream body for data.
UDP uses path template and HTTP/3 datagrams for data.
