commit a9e170e28636 ("scsi: qla2xxx: Fix uninitialized work element") moved initializiation of work element earlier in the probe to fix call stack. However, it still leaves a window where interrupt can be generated before work element is initialized. Fix that window by initializing work element before we are requesting IRQs.

After relogin is sucessful, "send_els_logo" flag needs to be reinitialized. This will allow next re-login to happen successfully. In target mode, this flag was not reset correctly, causing IO's failure during reset recovery and port ON/OFF test cases from initiator.

2017-08-30scsi: qla2xxx: Fix an integer overflow in sysfs codeDan Carpenter
The value of "size" comes from the user. When we add "start + size" it could lead to an integer overflow bug. It means we vmalloc() a lot more memory than we had intended. I believe that on 64 bit systems vmalloc() can succeed even if we ask it to allocate huge 4GB buffers. So we would get memory corruption and likely a crash when we call ha->isp_ops->write_optrom() and ->read_optrom(). Only root can trigger this bug.

2017-08-24scsi: qla2xxx: Do not call abort handler function during chip resetSawan Chandak
If there are IO's running and host reset or chip reset is triggered, IO's can fail due to rport time out. During chip reset recovery process, driver notifies the transport layer that remote port no longer exist, by calling fc_remote_port_delete(). When this function is called, it actually delays deletion by "blocking" it. It sets the remote port state to "FC_PORTSTATE_BLOCKED" and sets FC_RPORT_DEVLOSS_PENDING. When driver tries to abort the command by calling its abort handler function, abort handler will wait until remote port state is blocked state or wait for dev_loss_tmo time. Due to this blocking, rport times out and results in an IO failure. This patch adds a check for any active reset process before calling abort handler function.

Driver will perform following - Set PFLG_DRIVER_REMOVING flag and do not disable PCIe error reporting during adapter shutdown. - If PCIe device count is already zero, return correct error type from PCI error interface. - When device is offline, return correct error type from PCIe error path. - If there is board disable thread active during shutdown and PCIe device count is zero then cancel scheduling board disable thread during shutdown and return.

However, in function qla26xx_dport_diagnostics(), its return value is checked against NULL, which could result in failures.

This patch fixes system hang/crash while firmware dump is attempted with Block MQ enabled in qla2xxx driver. Fix is to remove check in fw dump template entries for existing request and response queues so that full buffer size is calculated during template size calculation. Following stack trace is seen during firmware dump capture process [ 694.390588] qla2xxx [0000:81:00.0]-5003:11: ISP System Error - mbx1=4b1fh mbx2=10h mbx3=2ah mbx7=0h.
