Subject: [PATCH] xiogetaddrinfo: support SOCK_RAW
The functions from xio-rawip.c call xiogetaddrinfo with this socktype.
Unfortunately, xiogetaddrinfo silently discards it.
For this reason IP-SENDTO function do not work with musl libc, e.g.
Alpine Linux. On these systems socat aborts with the following error
message:
socat - IP6-SENDTO:localhost:6
2019/08/12 22:48:34 socat[12846] E getaddrinfo("localhost", "NULL", {1,10,2,6}, {}): Unrecognized service
This patches fixes this issue.
