Hi folks,
Our LNST testing team uncovered a crash in ixgbe when running an XDP
program, see this report:
https://bugzilla.redhat.com/show_bug.cgi?id=2343204
>From looking at the code, it seems to me that the culprit is this commit:
c824125cbb18 ("ixgbe: Fix passing 0 to ERR_PTR in ixgbe_run_xdp()")
after that commit, the IS_ERR(skb) check in ixgbe_put_rx_buffer() no
longer triggers, and that function tries to dereference a NULL skb
pointer after an XDP program dropped the frame.
Could you please fix this?
And, erm, given the number of reviewed-by and tested-by tags in the
commit above, I'm guessing you don't have any XDP tests in your testing
regimen? Any chance you could add that? :)
Thanks!
