Hi,

this appears to be only half of the fix.

• hints.ai_socktype = type;
• hints.ai_flags = 0;
• hints.ai_protocol = proto;

• if (type == SOCK_RAW) {

• /* Workaround for glibc, that returns EAI_SERVICE (-8) if
  

•  * SOCK_RAW and IPPROTO_GRE is used.
  

•  */
  

• hints.ai_socktype = SOCK_DGRAM;
  

• hints.ai_protocol = IPPROTO_UDP;
  

• } else {

• hints.ai_socktype = type;
  

• hints.ai_protocol = proto;
  

• }

now rp->ai_socktype will be SOCK_DGRAM and rp->ai_protocol UDP. So the 'raw' socket for GRE will be a datagram socket for UDP.

E.g. you need the second hunk from my workaround[1]. I just wondered if you could think about a better way (one that can be easily dumped or ifdefed without putting the special case in the middle).
