Not _much_ added value, but I can add that I see a similar message - with 8 replacing 12 - when running netperf "omni" tests: netlink: 8 bytes leftover after parsing attributes. netlink: 8 bytes leftover after parsing attributes. netlink: 8 bytes leftover after parsing attributes. c12:~/netperf2_trunk# uname -a Linux c12 2.6.24-1-mckinley #1 SMP Sat Apr 19 00:19:28 UTC 2008 ia64 GNU/Linux And netperf was compiled on that system itself so ostensibly had the correct headers etc... I also see those messages on a 2.6.26-rc1 kernel: izzy:~/netperf2_trunk# ./configure --enable-omni ... izzy:~/netperf2_trunk# src/netperf -t omni -H c12.cup.hp.com -- -o foo OMNI TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to c12.cup.hp.com (16.89.133.212) port 0 AF_INET netlink: 8 bytes leftover after parsing attributes.
