When sniffing is enabled, the sniffer extracts the real domain from HTTP
Host header or TLS SNI and checks bypass rules against it. However, most
handlers were not passing WithBypass(...) to the sniffer, so the sniffer
internal bypass check was always skipped.
Additionally, the TLS-to-HTTP fallback paths in internal util sniffer
and forwarder also omitted bypass when constructing options for the
recursive HandleHTTP call after decrypting TLS.
Add WithBypass to all sniffer call sites that were missing it across
handlers (http, relay, socks4, socks5, ss, sshd, unix) and internal
TLS fallback paths.
Also fix import ordering in handler/http/connect.go.
Fixesgo-gost/gost#874
The go-gost fork of go-shadowsocks2 dropped built-in support for the
none/dummy cipher that was present in the original go-shadowsocks2.
Combined with the SS components' hard requirement for auth (and
therefore a valid cipher), this made gost fail to start with
method=none or method=dummy.
Add a no-op cipher in x/internal/util/ss/none/ that implements the
core.ShadowCipher interface using the standard go-shadowsocks2 AEAD
framing (salt + length-prefixed chunks, target address embedding)
without actual encryption. SaltSize=16 ensures random salts on every
connection to avoid bloom-ring replay detection.
Update SS TCP connector/handler and SS UDP connector/handler to detect
method=none/dummy (case-insensitive) and use the no-op cipher instead
of utils.NewClientConfig/NewServerConfig.
Fixesgo-gost/x#105
- Bump go-shadowsocks2 to v0.1.3 (new API symbols)
- Return error instead of nil when Target() is empty in TCP handler
- Reset wbuf unconditionally on write error to prevent unbounded growth
- Add nil guard on targetAddr before WriteTo to prevent panic
- Remove duplicate NewClientConfig call and dead ClientConfig literal
- Remove unused noDelay metadata field
- Fix buffer-size guard to catch negative values (len(b)==0 → bufSize<=0)
- Add address context to parse/session error messages
