[Qemu-devel] [Bug 1724590] [NEW] Usermode networking hostfwd only listens on IPv4

[Willem Mulder]

Public bug reported:

When forwarding ports in usermode networking (-net user,hostfwd=), QEMU
binds to IPv4 only. Therefore, connecting to the port over IPv6 results
in 'connection refused'.

I experienced this in QEMU 2.10.1, but it looks to still be present in
the current master (861cd431c99e56ddb5953ca1da164a9c32b477ca), since
slirp_hostfwd in net/slirp.c uses in_addr instead of in6_addr.
