[CVE-2017-18232][A][PATCH 00/11] CVE-2017-18232

[Khalid Elmously]

CVE-2017-18232

The first 4 patches are for cleanup purposes and are effectively no-ops. They make some of the later patches apply cleanly.

The remaining 7 patches are all part of the same series, which appears to be a re-working of the SAS event handling/queuing implementation.

Note that patch 10/11 is the one that effectively fixes the vulnerability (according to the CVE triage info) - however it seemed to me that patches 5-9 and patch 11 - all of which are part of the same series - are also needed, so I brought them in as well.

This CVE affects Trusty and Xenial in addition to Artful, however, I'm still working on the fix for Xenial which is proving more difficult, therefore sending just the Artful fix for now.

I've boot-tested this kernel but haven't run any scsi/sas-specific tests.


Jason Yan (11):
  scsi: libsas: kill useless ha_event and do some cleanup
  scsi: libsas: remove the numbering for each event enum
  scsi: libsas: remove unused port_gone_completion and DISCE_PORT_GONE
  scsi: libsas: rename notify_port_event() for consistency
  scsi: libsas: Use dynamic alloced work to avoid sas event lost
  scsi: libsas: shut down the PHY if events reached the threshold
  scsi: libsas: make the event threshold configurable
  scsi: libsas: Use new workqueue to run sas event and disco event
  scsi: libsas: use flush_workqueue to process disco events
    synchronously
  scsi: libsas: direct call probe and destruct
  scsi: libsas: notify event PORTE_BROADCAST_RCVD in
    sas_enable_revalidation()
