When connecting to an mDNS hostname that resolves to an IPv6 link-local address, connect() fails with EINVAL because sin6_scope_id is 0. This is a regression since 8.20.0 where the threaded resolver started splitting A and AAAA queries into separate getaddrinfo calls. The AAAA-only call with PF_INET6 may not set scope_id on systems where the same call with PF_UNSPEC did. When the resolver does not provide scope_id for a link-local address, try to determine it from the system's network interfaces using getifaddrs(). Also add scope_id to verbose connect output so the value can be seen in curl -v logs. Built and tested locally on Linux. checksrc passes. Fixes #21669 Reported-by: Bartel Sielski Closes #21728 |
