2008/7/23 Sepherosa Ziehau <sepherosa at gmail.com>: > 2) inpcb is on hash list (both the flag and the link fields prove that) tcp_connect_oncpu() first looks up the inpcb in the hash list then adds it if it is not already there. So if it is on the hash list when the os panics, could it mean that it was inserted by another thread after the failed look up?
