+
+    uTLS has had repeated fingerprinting vulnerabilities discovered by researchers.
+
+    uTLS is a Go library that attempts to imitate browser TLS fingerprints by copying

+    (Chrome uses BoringSSL, Firefox uses NSS) with distinct implementation behaviors
+    that cannot be replicated by simply copying the handshake format, making detection possible.
+    Additionally, the library lacks active maintenance and has poor code quality,

+
+    For TLS fingerprint resistance, use [NaiveProxy](/configuration/inbound/naive/) instead.

世界	e7a9c90213	Fix DNS cache lock goroutine leak The cache deduplication in Client.Exchange uses a channel-based lock per DNS question. Waiting goroutines blocked on <-cond without context awareness, causing them to accumulate indefinitely when the owning goroutine's transport call stalls. Add select on ctx.Done() so waiters respect context cancellation and timeouts.	2026-02-06 22:28:30 +08:00

Gavin Luo	fffe9fc566	Fix reset buffer in dhcp response loop Previously, the buffer was not reset within the response loop. If a packet handle failed or completed, the buffer retained its state. Specifically, if `ReadPacketFrom` returned `io.ErrShortBuffer`, the error was ignored via `continue`, but the buffer remained full. This caused the next read attempt to immediately fail with the same error, creating a tight busy-wait loop that consumed 100% CPU. Validates `buffer.Reset()` is called at the start of each iteration to ensure a clean state for 'ReadPacketFrom'.	2026-01-05 17:46:59 +08:00
