Title:
qeth: fix L3 next-hop im xmit qeth hdr
Status in Ubuntu on IBM z Systems:
Fix Released
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Xenial:
Fix Released
Bug description:
== SRU Justification ==
The current code accesses rtable->rt_gateway without checking that rtable
is a valid address. The accidental access to a lowcore area results in a
random next-hop address in the qeth_hdr. rtable (or more precisely,
skb_dst(skb)) can be NULL in rare cases (for instance together with AF_PACKET
sockets).
The solution is to add the missing NULL-ptr checks, which is done by
commit ec2c6726322f.
Commit ec2c6726322f is in mainline as of v4.13-rc5, so this fix is
only needed in Xenial.
== Fix ==
ec2c6726322f ("s390/qeth: fix L3 next-hop in xmit qeth hdr")
== Regression Potential ==
Low. Limited to s390.
== Test Case ==
A test kernel was built with this patch and tested by the original bug
reporter.
The bug reporter states the test kernel resolved the bug.
Upstream Commit:
ec2c6726322f0d270bab477e4904bf9496f70ee5
