Hi, I just got through a thread in misc@,
http://marc.info/?l=openbsd-misc&m=133934252713974&w=2 and it seems like the sample code in ip6(4) is wrong. I've made adjustments but it doesn't look as nice anymore, perhaps someone can look over it? These changes will really help someone first time trying the sample code, I think. Credit should be given to Simon Perreault, I just did what he suggested. -peter patch below (against 5.1): Index: ip6.4 =================================================================== RCS file: /cvs/src/share/man/man4/ip6.4,v retrieving revision 1.25 diff -u -r1.25 ip6.4 --- ip6.4 8 Sep 2011 16:43:56 -0000 1.25 +++ ip6.4 11 Jun 2012 19:26:44 -0000 @@ -251,6 +251,7 @@ }; .Ed .It Dv IPV6_HOPLIMIT Fa "int *" +.It Dv IPV6_RECVHOPLIMIT Fa "int *" Get or set whether the hop limit header field from subsequent packets will be provided as ancillary data along with the payload in subsequent .Xr recvmsg 2 @@ -590,7 +591,7 @@ * returned along with the payload. */ optval = 1; -if (setsockopt(s, IPPROTO_IPV6, IPV6_HOPLIMIT, &optval, +if (setsockopt(s, IPPROTO_IPV6, IPV6_RECVHOPLIMIT, &optval, sizeof(optval)) == -1) err(1, "setsockopt"); @@ -685,6 +686,15 @@ .%A B.
