I'm about to do one week of benchmarking and profiling using an Ixia four-port Gigabit Traffic generator and a Sun Fire v20z dual Opteron box in the Astaro labs. Let's hope I can find some code pieces in the network stack that can be optimized in order to achieve higher performance...

No big news this week - I'm in Astaro labs
[ /linux | permanent link ]
xfrm_user.c doesn't use netlink correctly
If you read the netlink documentation (and look on how existing users such as rtnetlink or ipt_ULOG uses it), then all messages part of a dump have the NLM_F_MULTI flag set, and the dump is terminated with a NLMSG_DONE message.
The code in net/xfrm/xfrm_user.c however dumps those messages without the NLM_F_MULTI flag. I've hacked a first patch, but apparently it doesn't catch all cases.
