This is just a cleanup. The unneeded NULL check annoys static checkers because we already derefenced it and the we check it and then (if it's not the _safe() version) we dereference it again without checking. And the static checker is all, "Wah? Is it null or not?"

Support is added for quiescence mode. This feature is for P3P adapters. Any of the functions can put the firmware into quiescence state. All the others have to ack that request. During quiescence mode current commands are processed and all the new incoming I/Os are blocked. Loop resync is performed after firmware comes out of quiescence state.

由 James Bottomley 提交于
Our current handling of medium error assumes that data is returned up to the bad sector. This assumption holds good for all disk devices, all DIF arrays and most ordinary arrays. However, an LSI array engine was recently discovered which reports a medium error without returning any data. This means that when we report good data up to the medium error, we've reported junk originally in the buffer as good. Worse, if the read consists of requested data plus a readahead, and the error occurs in readahead, we'll just strip off the readahead and report junk up to userspace as good data with no error. The fix for this is to have the error position computation take into account the amount of data returned by the driver using the scsi residual data. Unfortunately, not every driver fills in this data, but for those who don't, it's set to zero, which means we'll think a full set of data was transferred and the behaviour will be identical to the prior behaviour of the code (believe the buffer up to the error sector). All modern drivers seem to set the residual, so that should fix up the LSI failure/corruption case.

Currently, when scsi_dh_activate() returns with an error (e.g. SCSI_DH_NOSYS) the activate_complete callback is not called and the error is not propagated to DM mpath. When a SCSI device attached to a device handler is deleted, userland processes currently performing I/O on the device will have their I/O hang forever. - Set SCSI_DH_NOSYS error when the handler is in the process of being deleted (e.g. the SCSI device is in a SDEV_CANCEL or SDEV_DEL state). - Set SCSI_DH_DEV_OFFLINED error when device is in SDEV_OFFLINE state. - Call the activate_complete callback function directly from scsi_dh_activate if an error has been set (when either the scsi_dh internal data has already been deleted or is in the process of being deleted). The patch was tested in an iSCSI environment, RDAC H/W handler and multipath. In the following reproduction process, dd will I/O hang forever and the only way to release it will be to reboot the machine: 1) Perform I/O on a multipath device: dd if=/dev/dm-0 of=/dev/zero bs=8k count=1000000 & 2) Delete all slave SCSI devices contained in the mpath device: I) In an iSCSI environment, the easiest way to do this is by stopping iSCSI: /etc/init.d/iscsi stop II) Another way to delete the devices is by applying the following bash scriptlet: dm_devs=$(ls /sys/block/ | grep dm- | xargs) for dm_dev in $dm_devs; do devices=$(ls /sys/block/$dm_dev/slaves) for device in $devices; do echo 1 > /sys/block/$device/device/delete done done NOTE: when DM mpath's fail_path uses blk_abort_queue this scsi_dh change isn't strictly required. However, DM mpath's call to blk_abort_queue will soon be reverted because it has proven to be unsafe due to a race (between blk_abort_queue and scsi_request_fn) that can lead to list corruption. Therefore we cannot rely on blk_abort_queue via fail_path, but even if we could this scsi_dh change is still preferrable.

Fix iotag handling: 1) Update and check io tag for retry case. 2) Clearing upper 3 bits in io tag when an IO completes. The 3 upper bits in io tags are used for counting FCP exchange retry. Un-cleared bits will cause firmware to access invalid memory when the same io tag is used for an IO to a target that doesn't support FCP exchange retry. 3) Only check the effective bits when validating an iotag. Other minor fixes: 1) Added trace to get FC header type with assert of unhandled packet received. Ignore the type FC_TYPE_FC_FSS (FC_XS). 2) Fixed the adapter info display check - to check for fcmode flag even.

When the bfa driver is loaded a flogi is sent without the knowledge of trunking configuration. This normal flogi causes the switch ports which had trunking enabled to go to persistent offline. Solution is to store the port configuration (which has trunking info) in the flash for persistency. The firmware will read this configuration when the very first fcport enable is received.
