* [SCSI] scsi_transport_fc: replace BUS_ID_SIZE by fixed countJames Bottomley2009-06-211-1/+1

* sd, sr: fix Driver 'sd' needs updating messageHannes Reinecke2009-06-215-18/+3
| | | | | | | | | | | | If a SCSI ULD driver sets blk_queue_prep_rq(), it should clean it up itself on remove(), and not from the bus callbacks. This removes the need to hook into bus->remove(), which should not be used at the same time as driver->remove().

* fc_transport: The softirq_done function registration for BSG requestGiridhar Malavali2009-06-211-18/+19
| | | | | | | | | | | | | | Registered the softirq_done function, since this is requried iby an request using block level request timeout functionality. This function will be called by the block layer as part of time out clean process to release the BSG request. Moved some of the BSG request completion activities to softirq_done routine to take care of both normal and timout completions.

* ibmvfc: Fix endless PRLI loop in discoveryBrian King2009-06-212-4/+13
| | | | | | | | | | | | Fixes a problem seen where sending a PRLI to a target resulted in it sending a LOGO. This caused the ibmvfc driver to go back through discovery again, which caused another PRLI attempt, which caused another LOGO. Fix this behavior by ignoring LOGO if we haven't even logged into the target yet.

* ibmvfc: Process async events before command responsesBrian King2009-06-211-10/+10

* libfc: Add runtime debugging with debug_logging module parameterRobert Love2009-06-215-279/+235
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds the /sys/module/libfc/parameters/debug_logging file to sysfs as a module parameter. It accepts an integer bitmask for logging. Currently it supports: bit LSB 0 = general libfc debugging 1 = lport debugging 2 = disc debugging 3 = rport debugging 4 = fcp debugging 5 = EM debugging 6 = exch/seq debugging 7 = scsi logging (mostly error handling) the other bits are not used at this time. The patch converts all of the libfc source files to use these new macros and removes the old FC_DBG macro.

* libfcoe: Add runtime debugging with module param debug_loggingRobert Love2009-06-211-40/+54
| | | | | | | | | | | | | | | This patch adds a 'debug_logging' module parameter to libfcoe.ko. It is an unsigned int that represents a bitmask of available debug logging levels, each of which can be tuned at runtime. Currently there are only two logging levels for this module- bit LSB 0 = libfcoe general logging 1 = FIP logging Signed-off-by: Robert Love <robert.w.love@intel.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
* fcoe: Add runtime debug logging with module parameter debug_loggingRobert Love2009-06-212-55/+77
| | | | | | | | | | | | | | | | | | | | This patch converts all FC_DBG statements to use new runtime tunable debug macros. The fcoe.ko module now has a debug_logging module parameter. fcoe_debug_logging is an unsigned integer representing a bitmask of all available logging levels. Currently only two logging levels are supported- bit LSB 0 = general fcoe logging 1 = netdevice related logging This patch also attempts to clean up some debug statement formatting so it's more readable.

* scsi_transport_spi: Blacklist Ultrium-3 tape for IU transfersJames Bottomley2009-06-212-1/+40
| | | | | | | | | | | | There have been several bug reports which identified the Ultrium-3 tape as just hanging up on the bus during certain types of IU transfer. The identified culpret is type 0x02 (MULTIPLE COMMAND) transfers. The only way to prevent this tape wedging is to prevent it from using IU transfers at all. So this patch uses the exported blacklist matching technology to recognise the drive and force it not to use IU transfers. Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
* scsi_transport_spi: use spi target settings instead of inquiry data for DVJames Bottomley2009-06-211-5/+6
| | | | | | | | | | Right at the moment, we carefully set up the spi_support_xx in the device configuration routines, but then we never actually use the results: we rely on the inquiry strings. If we're going to allow overrides to the inquiry data, we have to rely on our own internal settings. Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
* enhance device info matching for multiple tablesJames Bottomley2009-06-212-22/+240
| | | | | | | | | | | The current scsi_devinfo.c matching routines use a single table for the global blacklist. However, we're developing a need to blacklist from specific transports too (notably some tape drives using SPI which don't respond well to high speed protocols). Instead of developing separate blacklist matching for each transport class needing it, enhance the current list matching to permit multiple lists.

| | | | | | | | | | | | | | | The net layer might return -EAGAIN because it could not get space/mem within the sock sndtimeo or becuase the tcp/ip connection was down. For the latter we do not want to retry because the conn/session should just be shutdown and restarted. libiscsi knows the state of the session recovery so propogate this error to that layer. It will either do iscsi recovery or have us retry the operation. Right now if we have partially sent a pdu we would always retry the IO xmit slowing down recovery.

The patch creates a generic framework that lays on top of bsg and the SGIO v4 ioctl in order to pass transaction requests to LLDD's. The interface supports the following operations: On an fc_host basis: Request login to the specified N_Port_ID, creating an fc_rport. Request logout of the specified N_Port_ID, deleting an fc_rport Send ELS request to specified N_Port_ID w/o requiring a login, and wait for ELS response. Send CT request to specified N_Port_ID and wait for CT response. Login is required, but LLDD is allowed to manage login and decide whether it stays in place after the request is satisfied. Vendor-Unique request. Allows a LLDD-specific request to be passed to the LLDD, and the passing of a response back to the application. On an fc_rport basis: Send ELS request to nport and wait for ELS response. Send CT request to nport and wait for CT response. The patch also exports several headers from include/scsi such that they can be available to user-space applications: include/scsi/scsi.h include/scsi/scsi_netlink.h include/scsi/scsi_netlink_fc.h include/scsi/scsi_bsg_fc.h For further information, refer to the last RFC: http://marc.info/?l=linux-scsi&m=123436574018579&w=2 Note: Documentation is still spotty and will be added later.

And, three directory names(ex:/debug/, /debugfs/, /sys/kernel/debug/) is existed in kernel source like ftrace, DRM, Wireless, Documentation, Network[sky2]files to mount debugfs filesystem. debugfs means debug filesystem for debugging easy to use by greg kroah hartman. "/sys/kernel/debug/" name is suitable as directory name of debugfs filesystem. - debugfs related reference: http://lwn.net/Articles/334546/ Fix inconsistency of directory name to mount debugfs filesystem. * From Steven Rostedt - find_debugfs() and tracing_files() in this patch.
