Driver added mechanism to move ABTS/PUREX/RIDA mailbox to ATIO queue as part of commit id 41dc529a ("qla2xxx: Improve RSCN handling in driver"). This patch adds a check to only allow ABTS/PURX/RIDA to be moved to ATIO Queue for ISP83XX and ISP27XX. Cc: <stable@vger.kernel.org> # 4.11 Signed-off-by:

We need to add a bus reset no-op as without it some of the LUNs attached to a vport may go offline when the error handler escalates to host reset due to not having a bus reset handler in the driver. What happens is we escalate to host reset which does a soft link down/link up to reset the adapter. However with multiple vports attached it's been observed that if the vports do log back into the target within 5 seconds, the SCSI layer offlines the devices most likely due to a TUR timing out to verify that the device is online. Adding a bus reset handler will cause the TUR to be sent after the bus reset handler where the devices will still be online if the bus reset is initiated by sg_reset (which is the case in the test that was failing). The bus reset will succeed and not needlessly bring the device offline/online. Signed-off-by:

We should be using the same logic to do a soft reset of the FCoE function whether it is initiated via sg_reset or the fc_host issue_lip attribute. Refactor the host reset and fcoe reset handlers to use the preferred logic which is currently contained in qedf_eh_host_reset(). Signed-off-by:

If there are multiple descriptors for a particular type in a clear virtual link we receive, we will not process it correctly but rather take the last value. This can cause us not to not flap the virtual link as the value from the descriptors that we compare against the our stored FCF or fc_lport values may not match. Change this to do a comparison when processing the each descriptor instead of at the end and then set a bool if we need to do the reset. Signed-off-by:

The newly added suspend/resume support causes harmless warnings when CONFIG_PM is disabled: smartpqi/smartpqi_init.c:5147:12: error: 'pqi_ctrl_wait_for_pending_io' defined but not used [-Werror=unused-function] smartpqi/smartpqi_init.c:2019:13: error: 'pqi_wait_until_lun_reset_finished' defined but not used [-Werror=unused-function] smartpqi/smartpqi_init.c:2013:13: error: 'pqi_wait_until_scan_finished' defined but not used [-Werror=unused-function] We can avoid the warnings by removing the #ifdef around the handlers and instead marking them as __maybe_unused, which will let gcc drop the unused code silently.

When copying attributes, the len argument was padded out and the resulting memcpy() would copy beyond the end of the source buffer. Avoid this, and use size_t for val_len to avoid all the casts. Similarly, avoid source buffer casts and use void *. Additionally enforces val_len can be represented by u16 and that the DMA buffer was not overflowed. Fixes the size of mfa, which is not FC_FDMI_PORT_ATTR_MAXFRAMESIZE_LEN (but it will be padded up to 4). This was noticed by the future CONFIG_FORTIFY_SOURCE checks.

iscsiadm session login can fail with the following error: iscsiadm: Could not login to [iface: default, target: iqn.1986-03.com... iscsiadm: initiator reported error (9 - internal error) When /etc/iscsi/iscsid.conf sets node.session.cmds_max = 4096, it results in 64K-sized kmallocs per session. A system under fragmented slab pressure may not have any 64K objects available and fail iscsiadm session login. Even though memory objects of a smaller size are available, the large order allocation ends up failing.
