scsi: qedf: Fix crash when MFW calls for protocol stats while function is still probing · ad40f525

Chad Dupuis authored Apr 16, 2020

The MFW may make a call to qed and then to qedf for protocol statistics
while the function is still probing.  If this happens it's possible that
some members of the struct qedf_ctx may not be fully initialized which can
result in a NULL pointer dereference or general protection fault.

To prevent this, add a new flag call QEDF_PROBING and set it when the
__qedf_probe() function is active. Then in the qedf_get_protocol_tlv_data()
function we can check if the function is still probing and return
immediantely before any uninitialized structures can be touched.

scsi: qedf: Keep track of num of pending flogi · ab0a8299

Saurav Kashyap authored Apr 16, 2020

If a port is brought down for an extended period of time, the fipvlan
counter gets exhausted and the driver will fall back to default VLAN 1002
and call fcoe_ctlr_link_up to log in. However, the switch will discard the
FLOGI attempt because the VLAN is now different.

Keep track of the number of FLOGI attempts and if a threshold of
QEDF_FLOGI_RETRY_CNT is exceeded, perform a context soft reset.
