crypto_authenc_givencrypt_done uses req->data as struct aead_givcrypt_request, while it really points to a struct aead_request, causing this crash: BUG: unable to handle kernel paging request at 6b6b6b6b IP: [<dc87517b>] :authenc:crypto_authenc_genicv+0x23/0x109 *pde = 00000000 Oops: 0000 [#1] PREEMPT DEBUG_PAGEALLOC Modules linked in: hifn_795x authenc esp4 aead xfrm4_mode_tunnel sha1_generic hmac crypto_hash] Pid: 3074, comm: ping Not tainted (2.6.25 #4) EIP: 0060:[<dc87517b>] EFLAGS: 00010296 CPU: 0 EIP is at crypto_authenc_genicv+0x23/0x109 [authenc] EAX: daa04690 EBX: daa046e0 ECX: dab0a100 EDX: daa046b0 ESI: 6b6b6b6b EDI: dc872054 EBP: c033ff60 ESP: c033ff0c DS: 007b ES: 007b FS: 0000 GS: 0033 SS: 0068 Process ping (pid: 3074, ti=c033f000 task=db883a80 task.ti=dab6c000) Stack: 00000000 daa046b0 c0215a3e daa04690 dab0a100 00000000 ffffffff db9fd7f0 dba208c0 dbbb1720 00000001 daa04720 00000001 c033ff54 c0119ca9 dc852a75 c033ff60 c033ff60 daa046e0 00000000 00000001 c033ff6c dc87527b 00000001 Call Trace: [<c0215a3e>] ? dev_alloc_skb+0x14/0x29 [<c0119ca9>] ? printk+0x15/0x17 [<dc87527b>] ? crypto_authenc_givencrypt_done+0x1a/0x27 [authenc] [<dc850cca>] ? hifn_process_ready+0x34a/0x352 [hifn_795x] [<dc8353c7>] ? rhine_napipoll+0x3f2/0x3fd [via_rhine] [<dc851a56>] ? hifn_check_for_completion+0x4d/0xa6 [hifn_795x] [<dc851ab9>] ? hifn_tasklet_callback+0xa/0xc [hifn_795x] [<c011d046>] ? tasklet_action+0x3f/0x66 [<c011d230>] ? __do_softirq+0x38/0x7a [<c0105a5f>] ? do_softirq+0x3e/0x71 [<c011d17c>] ? irq_exit+0x2c/0x65 [<c010e0c0>] ? smp_apic_timer_interrupt+0x5f/0x6a [<c01042e4>] ? apic_timer_interrupt+0x28/0x30 [<dc851640>] ? hifn_handle_req+0x44a/0x50d [hifn_795x] ...
