This increases the probability of successful allocation. The allocation may still fail if this minimum order is > 0.

| * | | | | [SCSI] fix medium error problems with some arrays which can cause data ↵James Bottomley2010-12-221-1/+8

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.

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.

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.

They're accumulating bytes, not megabytes. The statistic returned via /sys must be in megabytes, however, which is what the HBA-API wants. The FCP code needs to accumulate it in bytes and then divide by 1,000,000 (not 2^20) before it presented via sysfs. This affects fcoe.ko only, not fnic. The fnic driver correctly by accumulating bytes and then converts to megabytes. I checked that libhbalinux is using the /sys file directly without conversion. BTW, qla2xxx does divide by 2^20, which I'm not fixing here.

So, when receiving an advertisement, move the FCF to the front of the list so that it gets chosen first among those with the same priority. Without this, more FLOGIs need to be sent in a test with multiple FCFs and a switch in NPV mode, but it still eventually finds one that accepts the FLOGI.
