BFA UF module did not hold lock when seding uf post buffer message to firmware causing CPE-Q corruption. Fix is to check present of FCS and if FCS present hold lock while posting UF buffers. Handle PRLO with sending acc to it and relogin with rport. Discard fcxp before any state change. Signed-off-by:

Clear PSS memory reset that is set as part of power-on-reset (pci reset). Complete PMM memory reset before BISTR start. Clear EDRAM BISTR start bit after fixed delay. BISTR DONE bit status is not getting set. Use a fixed 1ms delay for BISTR now. Expose PMM IT memory definitions to host. Signed-off-by:

Add a max retry limit for PRLI retries. Max retry limit (5) is same as used in rport PLOGI. Once the retries are exhausted, invoke rport offline so that existing logic of rport re-discovery can kick-in. Also fixed a bug in rport.c where one less retry was happening. Signed-off-by:

When a rport goes offline, its speed setting was not reset. Subsequently, if the rport was not deleted due to it coming back online within rport del timeout, previously discovered speed would continue to show up. The fix is to reset the speed when processing rport offline transition. In rport attributes, rport's with unknown speed were indicated as TRL enforced. The right thing do to would be to use TRL default speed to determine if TRL is enforced, when TRL is enabled. Signed-off-by:

Vport state machine does not cleanup associated lport in some states: while waiting for fdisc response or fdisc failure state. The fixe is to cleanup lport on vport delete in all states. In fdisc state, discard fdisc response and delete lport and wait for lport deletecompletion. in error state, delete lport and wait for delete completion. Signed-off-by:

This patch enables creating PBC vport. During fcs init, fcs will read PBC vport using bfa iocfc API and invoke fcb callback to add the pbc vport entries into a list. The pbc vport list will be traversed in the subsequent pci probe process and vport will be created using fc transport provided vport create function. Signed-off-by:

fixes surrounding PCIe enhanced error handling: (1) We need to reject all request generated internaly inside the driver as well as request arriving from the scsi mid layer when PCIe EEH is active. The fix is to add a per adapter flag called pci_error_recovery which is checked thru out the driver when request are generated. (2) We don't need to call the pci_driver->remove directly from the PCIe callbacks becuase its already called from the PCIe EEH code. In its place we are shutting down the watchdog timer, and flushing back all pending IO. (3) We need to save and restore the pci state across PCIe EEH handling. Signed-off-by:

In compliance to RFC793, a TCP graceful termination will be used instead of an abortive termination for the case where the remote has initiated the close of the connection. Additionally, a TCP abortive termination will be used to close the connection when a logout response is not received in time after a logout request has been initiated. Signed-off-by:

Added variables to separate the fine tuned timeout values for connection destroy and context destroy for both 1g and 10g devices. v2: Extended the 5771X disconnect timeout from 10s to 20s as the firmware has a retransmission timeout of 16s. This fixes one of the iscsi_endpoint leak issues when the target is slow or non-responsive to our TCP FIN. Signed-off-by:

For cases where the iSCSI disconnection procedure times out due to the iSCSI daemon being slow or unresponsive, the bnx2i_stop routine will now perform hardware cleanup via bnx2i_hw_ep_disconnect on all active endpoints so that subsequent operations will perform properly. Also moved the mutex locks inside ep_connect and ep_disconnect so that proper exclusivity can resolve simultaneous calls to the ep_disconnect routine. v2: Removed the unnecessary read lock in the bnx2i_stop Signed-off-by:

If the user accidentally changes LUN mappings or it occurs due to a bug, then it can cause data corruption that can take months and months to track down. This patch adds a log message when getting REPORT_LUNS_DATA_CHANGED and it adds a generic message for other Unit Attentions with asc == 0x3f. We are working on adding support for handling of these errors, but I think until then we should at least log a message so tracking down problems as a result of one of these changes is a little easier.

This patch fixes mptsas disk hot-removal processing. The hot-removal processing doesn't complete because of this condition. drivers/message/fusion/mptsas.c: mptsas_taskmgmt_complete() if ((mptsas_find_vtarget(ioc, channel, id)) && !ioc->fw_events_off) mptsas_queue_device_delete(...); mptsas_queue_device_delete(), which must be called for hot-removal, never gets called because mptsas_find_vtarget() always returns 0 here. At that time, the vtarget has already been freed in mptsas_target_destroy(), and also the scsi_device has been marked as SDEV_DEL. As a result of the issue, port deletion functions won't get called and the device ends up being in an incomplete state. (Some data structures and sysfs entries, which should be removed in hot-removal, remain.) One side effect of this is that a hot-addition of the device (bringing the device back on) fails. This patch just removes mptsas_find_vtarget() from the if-state condition. Signed-off-by: -

If we encounter an error when sending a management datagram (i.e. non SCSI command, such as virtual adapter initialization command), we end up incrementing the request_limit, even though we don't decrement it for these commands. Fix this up by doing this increment in the error path for SRP commands only. Signed-off-by:

Fixes a deadlock that can occur if we hit a command timeout during the virtual adapter initialization. The event done functions are written with the assumption that no locks are held, however, when purging requests this is not true. Fix up the purge function to drop the lock so that the done function is not called with the lock held, which can cause a deadlock. Signed-off-by:

This fixes a softlockup seen on resume. During resume, the CRQ must be reenabled. However, the H_ENABLE_CRQ hcall used to do this may return H_BUSY or H_LONG_BUSY. When this happens, the caller is expected to retry later. This patch changes a simple loop, which was causing the softlockup, to a loop at task level which sleeps between retries rather than simply spinning. Signed-off-by:

This fixes a softlockup seen on resume. During resume, the CRQ must be reenabled. However, the H_ENABLE_CRQ hcall used to do this may return H_BUSY or H_LONG_BUSY. When this happens, the caller is expected to retry later. Normally the H_ENABLE_CRQ succeeds relatively soon. However, we have seen cases where this can take long enough to see softlockup warnings.
