SKB dst field is NULL when AEAD request complete() is called

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

 



Working with kernel 3.12.14, in AEAD mode, I register my crypto driver
and the givencrypt() method in the driver gets called when I send
IPSec traffic. I store the request, and later call its complete()
method from a work queue. There is no actual encryption happening at
the moment, I'm just testing flow. As stated, the complete() call
stumbles upon a NULL pointer exception in xfrm_output_resume() because
skb_dst(skb) is NULL. When I receive the request in givencrypt(), dst
is not null in the SKB.

Why would the framework meddle with the SKB? Has anyone experienced
anything similar?

Thanks,
Dennis.
