xfrm: Flushing empty SAD generates false events
To see the effect make sure you have an empty SAD. -On window1 "ip xfrm mon" -on window2 issue "ip xfrm state flush" You get prompt back in window1 and you see the flush event on window2. With this fix, you still get prompt on window1 but no event on window2. I was tempted to return -ESRCH on window1 (which would show "RTNETLINK answers: No such process") but didnt want to change current behavior. cheers, jamal commit 5f3dd4a772326166e1bcf54acc2391df00dc7ab5 Author: Jamal Hadi Salim <hadi@cyberus.ca> Date: Thu Feb 11 04:41:36 2010 -0500 xfrm: Flushing empty SAD generates false events To see the effect make sure you have an empty SAD.
