Description of problem: glibc doesn't provide definitions needed to support standard (rfc3542) IPV6 socket properties. For example to obtain the MTU value of the path, the IPV6_PATHMTU option to getsockopt() can be used. This is supported by the Linux kernel but not by glibc. How reproducible: Compile the following program. #define _GNU_SOURCE #include <unistd.h> #include <netinet/in.h> #include <sys/types.h> #include <sys/socket.h> int main() { struct ip6_mtuinfo mtuinfo; socklen_t len; getsockopt(1, IPPROTO_IPV6, IPV6_PATHMTU, &mtuinfo, &len); return 0; } Actual results: Fails because IPV6_PATHMTU is undefined. Expected results: Compilation should complete. Additional info: A bug report and a fix was posted in Debian: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=753909
Fixed upstream. commit 1c1e3125206ef810dc7282023f6267a33b486233 Author: Carlos O'Donell <carlos> Date: Wed Jul 8 09:26:45 2015 -0400 Add missing Advanced API (RFC3542) (1) defines. Fixes bug 18643. Defines IPV6_RECVPATHMTU, IPV6_PATHMTU, and IPV6_DONTFRAG for Linux.
Thanks.
