Log:
MFC of jail fixes regarding INADDR_LOOPBACK. -CURRENT commit message:
Anton kindly pointed out (and fixed) a bug in the Jail handling of the
bind() call on IPv4 sockets:
Currently, if one tries to bind a socket using INADDR_LOOPBACK inside a
jail, it will fail because prison_ip() does not take this possibility
into account. On the other hand, when one tries to connect(), for
example, to localhost, prison_remote_ip() will silently convert
INADDR_LOOPBACK to the jail's IP address. Therefore, it is desirable to
make bind() to do this implicit conversion as well.
Apart from this, the patch also replaces 0x7f000001 in
prison_remote_ip() to a more correct INADDR_LOOPBACK.
