- pkg/nathole: add RLock when reading clientCfgs map in PreCheck path
to prevent concurrent map read/write crash
- server/proxy: fix error variable shadowing in GetWorkConnFromPool
that could return a closed connection with nil error
- pkg/util/net: check ListenUDP error before spawning goroutines
and assign readConn to struct field so Close() works correctly
- Replace duplicate parseBasicAuth with existing httppkg.ParseBasicAuth
- Extract buildDomains helper in BaseProxy for HTTP/HTTPS/TCPMux proxies
- Extract toProxyStats helper to deduplicate ProxyStats construction
- Extract startVisitorListener helper in BaseProxy for STCP/SUDP proxies
- Extract acceptLoop helper in BaseVisitor for STCP/XTCP visitors
In AddPrefix, the loop `for _, p := range l.prefixes` creates a copy
of each element. Assignments to p.Value and p.Priority only modify
the local copy, not the original slice element, causing updates to
existing prefixes to be silently lost.
This affects client/service.go where AddPrefix is called with
Name:"runID" on reconnection — the old runID value would persist
in log output instead of being updated to the new one.
Fix by using index-based access `l.prefixes[i]` to modify the
original slice element, and add break since prefix names are unique.
- pkg/util/net/websocket.go: store ln parameter in struct to prevent
nil pointer panic when Addr() is called
- pkg/auth/oidc.go: replace unsynchronized []string with map + RWMutex
for subjectsFromLogin to fix data race across concurrent connections
The CloseNotifyConn.Close() function calls itself if the closeFlag is equal to 0 which would mean it would immediately swap the closeFlag value to 1 and never call closeFn. It is unclear what the intent of this call to cc.Close() was but I assume it was meant to be a call to close the Conn object instead.
- Update go.mod to use github.com/quic-go/quic-go v0.53.0
- Replace quic.Connection interface with *quic.Conn struct
- Replace quic.Stream interface with *quic.Stream struct
- Update all affected files to use new API:
- pkg/util/net/conn.go: Update QuicStreamToNetConn function and wrapQuicStream struct
- server/service.go: Update HandleQUICListener function parameter
- client/visitor/xtcp.go: Update QUICTunnelSession struct field
- client/connector.go: Update defaultConnectorImpl struct field
Fixes#4852
