Has anyone seen the following problem on Linux 3.10, or later Linux? If it is fixed, can anyone point out where the fix is? Thanks. Chemin We are running Android, based on Linux3.10. With our crypto hardware accelerator, and driver, algorithm of "authenc(hmac(sha1),cbc(aes))" is running well. With our hardware accelerator and algorithm of "rfc4309(ccm(aes))", it is running fine too. We start testing extended sequence number recently. ip xfrm state is set with flag esn and replay-window 256. System crashes shortly, after the first couple of packet transmits. We try to run the same test with flag esn and replay-window 256 with algorithm of "rfc4309(ccm(aes))", it still runs fine with hardware accelerator. We go back to the same algorithm of "authenc(hmac(sha1),cbc(aes))" but without hardware accelerator. This time, it runs fine. The crypto hardware driver is agnostic to esn. Without esn, it is running fine. So it is less likely driver is at fault. When it crashes, the stack dump looks like the following # ping 10.2.242.93 -I 192.168.2.10 PING 10.2.242.93 (10.2.242.93) from 192.168.2.10: 56 data byt 329.068077] Unable to handle kernel NULL
