IBM is requesting these commits in s390 for X, B and C. The bug
description the commits fix is as follows:
Description: qeth: Fix potential array overrun in cmd/rc lookup Symptom:
Infinite loop when processing a received cmd.
Problem: qeth_get_ipa_cmd_name() and qeth_get_ipa_msg() are used to build
human-readable messages for received cmd data.

its function")
048a7f8b4ec0 ("s390: qeth: Fix potential array overrun in cmd/rc lookup")
== Regression Potential ==
Low. Limited to s390.
== Test Case ==
A test kernel was built with these two patches and tested by IBM.
The bug reporter states the test kernel resolved the bug.
Description: qeth: Fix potential array overrun in cmd/rc lookup
Symptom: Infinite loop when processing a received cmd.
Problem: qeth_get_ipa_cmd_name() and qeth_get_ipa_msg() are used
to build human-readable messages for received cmd data.
They store the to-be translated value in the last entry of a
global array, and then iterate over each entry until they found
the queried value (and the corresponding message string).
If there is no prior match, the lookup is intended to stop at
the final entry (which was previously prepared).
If two qeth devices are concurrently processing a received cmd,
one lookup can over-write the last entry of the global array
while a second lookup is in process. This second lookup will
then
never hit its stop-condition, and loop.
Solution: Remove the modification of the global array, and limit the
number
of iterations to the size of the array.
