[BUG] 2.6.20 Oopses in xfrm_audit_log

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi All,

i upgraded to vanilla kernel 2.6.20 and while i was using strongswan 2.8.2 to setup an IPSEC VPN i got the following kernel Ooops. I had successfully established the same tunnel a few times, but key renegotiation caused a problem ( both ends did not renegotiate at the same time so the tunnel was frozen ), i decided to kill the tunnel and start a new one ( using ipsec auto --down tunnel & ipsec auto --up tunnel ), while i was doing so, i got the oops.

BUG: unable to handle kernel NULL pointer dereference at virtual address 00000188
printing eip:
c02fb85c
*pde = 00000000
Oops: 0000 [#1]
