2013-06-26[SCSI] sd: Update WRITE SAME heuristicsMartin K. Petersen3-18/+37
SATA drives located behind a SAS controller would incorrectly receive WRITE SAME commands. Tweak the heuristics so that: - If REPORT SUPPORTED OPERATION CODES is provided we will use that to choose between WRITE SAME(16), WRITE SAME(10) and disabled. This also fixes an issue with the old code which would issue WRITE SAME(10) despite the command not being whitelisted in REPORT SUPPORTED OPERATION CODES. - If REPORT SUPPORTED OPERATION CODES is not provided we will fall back to WRITE SAME(10) unless the device has an ATA Information VPD page. The assumption is that a SATL which is smart enough to implement WRITE SAME would also provide REPORT SUPPORTED OPERATION CODES. To facilitate the new heuristics scsi_report_opcode() has been modified to so we can distinguish between "operation not supported" and "RSOC not supported". Reported-by: H.

2013-06-26[SCSI] bfa: kdump fix on 815 and 825 adaptersVijaya Mohan Guvva5-24/+150
Root cause: When kernel crashes, On brocade 815/825 adapters, bfa IOC state machine and FW doesn't get a notification and hence are not cleanly shutdown. So registers holding driver/IOC state information are not reset back to valid disabled/parking values. This causes subsequent driver initialization to fail during kdump kernel boot. Fix description: during the initialization of first PCI function, reset corresponding register when unclean shutown is detect by reading chip registers.

2013-06-26[SCSI] bfa: Add dynamic diagnostic port supportVijaya Mohan Guvva7-89/+781
D-Port is a new port type created with the intention of running link level diagnostic tests like loopback, traffic test. In static D-port mode, user configures the port to D-port mode and starts the test, but in dynamic D-port, once the Brocade switch port is configured to D-port, it will reject the regular FLOGI from HBA with reason that it is in D-port mode. So based on the reason code HBA port will turn itself into D-port and start diagnostic test.

The 'ctl' field of the 'struct ata_taskfile' is not really dual purpose, i.e. it is not intended for storing the alternate status register (which is mapped at the same address in the legacy IDE controllers) in the qc_fill_rtf() method. No other 'libata' driver except 'drivers/scsi/ipr.c' stores the alternate status register's value in the 'ctl' field of 'qc->result_tf', hence this driver should not do this as well...

2013-06-25fcoe: Use correct API to set vlan tag for FCoE Ethertype skbsRobert Love1-2/+5
fcoe_xmit was coded such that it would skip the vlan net device/layer and instead set some vlan flags and transmit on the real net device. The real net device has code that would add the vlan tag for fcoe skbs. This avoids some extra processing for data frames and provides a small performance improvement. Since fcoe_xmit was not using the vlan net device, __vlan_put_tag within the real net device's xmit routine was ultimately being called to set the vlan tag. With the below change the behavior of __vlan_put_tag changed slightly, it now sets the skb->protocol = vlan_proto. vlan_proto was not a field being set by fcoe_xmit, so the skb->protocol is now not being set to ETH_P_8021Q, as it should be. This patch converts fcoe_xmit to use the vlan_put_tag routine which will tag the skb and fcoe will continue to transmit fcoe skbs on the real net device. For reference, the below change was the one that altered the __vlan_put_tag behavior. commit 86a9bad3ab6b6f858fd4443b48738cabbb6d094c Author: Patrick McHardy <[email protected]> Date: Fri Apr 19 02:04:30 2013 +0000 net: vlan: add protocol argument to packet tagging functions Add a protocol argument to the VLAN packet tagging functions. In case of HW tagging, we need that protocol available in the ndo_start_xmit functions, so it is stored in a new field in the skb. The new field fits into a hole (on 64 bit) and doesn't increase the sks's size.

2013-06-24[SCSI] megaraid_sas: Add support for Uneven Span PRL11[email protected]5-50/+904
MegaRAID older Firmware does not support uneven span configuration for PRL11. E.g User wants to create 34 Driver PRL11 config, it was not possible using old firmware, since it was not supported configuration in old firmware Old Firmware expect even number of Drives in each span and same number of physical drives at each span. Considering above design, 17 Drives at Span-0 and 17 drives at span-1 was not possible. Now, using this new feature Firmware and Driver both required changes. New Firmware can allow user to create 16 Drives at span-0 and 18 Drives at span-1. This will allow user to create 34 Drives Uneven span PRL11. RAID map is interface between Driver and FW to fetch all required fields(attributes) for each Virtual Drives. Since legacy RAID map consider Even Span design, there was no place to keep Uneven span information in existing Raid map. Because of this limitation, for Uneven span VD, driver can not use RAID map. This patch address the changes required in Driver to support Uneven span PRL11 support. 1. Driver will find if Firmware has UnevenSpanSupport or not by reading Controller Info. 2. If Firmware has UnvenSpan PRL11 support, then Driver will inform about its capability of handling UnevenSpan PRL11 to the firmware. 3. Driver will update its copy of span info on each time Raid map update is called. 4. Follow different IO path if it is Uneven Span. (For Uneven Span, Driver uses Span Set info to find relavent fields for that particular Virtual Disk) More verbose prints will be available by setting "SPAN_DEBUG" to 1 at compilation time.
