Description: qeth: fix length check in SNMP processing
Symptom: Undefined behaviour.
Problem: The response for a SNMP request can consist of multiple parts,
which the cmd callback stages into a kernel buffer until all
parts have been received. If the callback detects that the
staging buffer provides insufficient space, it bails out with
error.
This processing is buggy for the first part of the response -
while it initially checks for a length of 'data_len', it later
copies an additional amount of
'offsetof(struct qeth_snmp_cmd, data)' bytes.
Solution: Fix the calculation of 'data_len' for the first part of the
response.
Upstream-ID: 9a764c1e59684c0358e16ccaafd870629f2cfe67
Should be applied to all Ubuntu Releases in Service |
== SRU Justification ==
The response for a SNMP request can consist of multiple parts,
which the cmd callback stages into a kernel buffer until all
parts have been received. If the callback detects that the
staging buffer provides insufficient space, it bails out with
error.
This processing is buggy for the first part of the response -
while it initially checks for a length of 'data_len', it later
copies an additional amount of
'offsetof(struct qeth_snmp_cmd, data)' bytes.
== Fix ==
9a764c1e5968 ("s390/qeth: fix length check in SNMP processing")
== Regression Potential ==
Low. Changes 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.
