            Bug ID: 59427
           Summary: ws2_32: setsockopt(IP_RECVECN/IPV6_RECVECN) fails with
                    WSAENOPROTOOPT (10042) (Unknown optname 0x32)
           Product: Wine
           Version: 11.0
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winsock

Created attachment 80395
  --> http://bugs.winehq.org/attachment.cgi?id=80395
Minimal repro (Rust) + WINEDEBUG=+winsock log (Unknown optname 0x32,
WSAENOPROTOOPT 10042)

Wine 11.0 (Arch Linux) does not recognize Winsock ECN recv options.

Repro:
Run attached ecn_probe under 64-bit Wine. It creates IPv4/IPv6 UDP sockets and
calls:
- setsockopt(IPPROTO_IP, IP_RECVECN, 1)
- setsockopt(IPPROTO_IPV6, IPV6_RECVECN, 1)

Observed:
Wine prints:
fixme:winsock:setsockopt Unknown IPPROTO_IP optname 0x00000032
fixme:winsock:setsockopt Unknown IPPROTO_IPV6 optname 0x00000032
and setsockopt fails with WSAENOPROTOOPT (10042) for both.

Expected:
These options should be supported as part of Winsock ECN support.

Environment:
Host: Arch Linux x86_64
Kernel: Linux archog 6.14.0-rt3-arch1-6-rt
Wine: 11.0

Is there an application that depends on this?

(In reply to Zeb Figura from comment #1)
> Is there an application that depends on this?

Yes.
One concrete consumer is the Rust QUIC stack "quinn" (via its `quinn-udp`
crate). On Windows it enables ECN reception using `setsockopt(IPPROTO_IP,
IP_RECVECN, 1)` / `setsockopt(IPPROTO_IPV6, IPV6_RECVECN, 1)` so it can read
ECN bits from incoming packets.

Under Wine 11.0 these calls fail with WSAENOPROTOOPT (10042) and “Unknown …
optname 0x32”, which can prevent QUIC endpoint creation (i.e. the application
fails to start under Wine/Proton if ECN is enabled unconditionally).
