Hello Kazuyoshi-san, Thanks for this patch. Is it tested with IPv6? Other than that question, it looks sane to me at a *very* quick first glance; I'm about to go out for the evening so will look more closely later. I installed a bunch of *BSD virtual machines, along with OpenIndiana, for testing the 3.14 release so I should be able to test that it's OK to remove the #ifdef __sun__. By the way, do you have any thoughts on https://plus.google.com/113990329890790578682/posts/5qpUJD3ukXV I'll cite parts of the forum post since Oracle's forums have been down for the last few days... https://forums.oracle.com/forums/thread.jspa?threadID=2311191 CSTP connected.
