PV6 bind fails with 49 (#define EADDRNOTAVAIL 49 /* Can't assign requested address */)

[Sreenivasa Honnur]

roundhay# sysctl -a | grep jailed
security.jail.jailed: 0

Oh, of course, I mean, what do you have in td->td_ucred?
[Sreenivas] not sure, I referred to socreate() usage in the kernel source and used it.

One more observation. Interface "cxgbe1" has a IPv6 interface and an IPv4 interface, print in ifa_ifwithaddr_internal () shows like below

ifp->xname:cxgbe1 ifp->dname:cxgbe
ifa->ifa_addr->sa_family:18 addr->sa_family:28 ==> this is for AF_LINK
ifa->ifa_addr->sa_family:2 addr->sa_family:28 ==> for AF_INET

Though cxgbe1 has a IPv6 interface there is no entry for AF_INET6

Interface "cxgbe3" is not configured with any IP, print in ifa_ifwithaddr_internal () shows like below
ifp->xname:cxgbe3 ifp->dname:cxgbe
ifa->ifa_addr->sa_family:18 addr->sa_family:28 ==> for AF_LINK

Oh, of course, I mean, what do you have in td->td_ucred?
