[bug-gnulib] [PATCH]: getaddrinfo module broken

[Yoann Vandoorselaere]

Hi,

Here is a patch that address several issues in the getaddrinfo GnuLib
module implementation:

- getaddrinfo might be available from -lnls or -lsocket. Look that up.

- Don't fail when SOCK_STREAM or SOCK_DGRAM are specified in ai_socktype
(most getaddrinfo usage involve using it, this was making the module
unusable).

- Fix invalid ai_protocol check. ai_protocol is usually set to 0 or
depending on ai_family/ai_socktype to IPPROTO_TCP / IPPROTO_UDP. 
Checking for SOCK_STREAM / SOCK_DGRAM in ai_protocol was invalid.

- Set ai_socktype / ai_protocol in the returned addrinfo structure.


I'm using this patch in Prelude for a while and it definitely fixed most
of the bug experienced by people lacking a getaddrinfo() implementation.

Regards,
