* [SCSI] fnic: fix incorrect use of SLAB_CACHE_DMA flagAbhijeet Joglekar2011-06-293-19/+6
| | | | | | | | | | | Driver was incorrectly using the SLAB_CACHE_DMA flag when creating a cache for SGLs. fnic device does not have 24-bit DMA restrictions. Remove the flag and allocations from ZONE_DMA. Thanks to Roland Dreier and David Rientjes for pointing out the bug.

* SCSI host lock push-downJeff Garzik2010-11-162-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | Move the mid-layer's ->queuecommand() invocation from being locked with the host lock to being unlocked to facilitate speeding up the critical path for drivers who don't need this lock taken anyway. The patch below presents a simple SCSI host lock push-down as an equivalent transformation. No locking or other behavior should change with this patch. All existing bugs and locking orders are preserved. Additionally, add one parameter to queuecommand, struct Scsi_Host * and remove one parameter from queuecommand, void (*done)(struct scsi_cmnd *) Scsi_Host* is a convenient pointer that most host drivers need anyway, and 'done' is redundant to struct scsi_cmnd->scsi_done. Minimal code disturbance was attempted with this change. Most drivers needed only two one-line modifications for their host lock push-down.

| | | | | | | | | | | | | | This removes the driver's get_host_def_dev_loss_tmo callback and just has the driver set the dev loss using the fc class fc_host_dev_loss_tmo macro like is done for other fc params.

* [SCSI] libfcoe: fcoe: fnic: add FIP VN2VN point-to-multipoint supportJoe Eykholt2010-07-281-6/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The FC-BB-6 committee is proposing a new FIP usage model called VN_port to VN_port mode. It allows VN_ports to discover each other over a loss-free L2 Ethernet without any FCF or Fibre-channel fabric services. This is point-to-multipoint. There is also a variant of this called point-to-point which provides for making sure there is just one pair of ports operating over the Ethernet fabric. We add these new states: VNMP_START, _PROBE1, _PROBE2, _CLAIM, and _UP. These usually go quickly in that sequence. After waiting a random amount of time up to 100 ms in START, we select a pseudo-random proposed locally-unique port ID and send out probes in states PROBE1 and PROBE2, 100 ms apart. If no probe responses are heard, we proceed to CLAIM state 400 ms later and send a claim notification. We wait another 400 ms to receive claim responses, which give us a list of the other nodes on the network, including their FC-4 capabilities. After another 400 ms we go to VNMP_UP state and should start interoperating with any of the nodes for whic we receivec claim responses. More details are in the spec.j Add the new mode as FIP_MODE_VN2VN. The driver must specify explicitly that it wants to operate in this mode. There is no automatic detection between point-to-multipoint and fabric mode, and the local port initialization is affected, so it isn't anticipated that there will ever be any such automatic switchover. It may eventually be possible to have both fabric and VN2VN modes on the same L2 network, which may be done by two separate local VN_ports (lports). When in VN2VN mode, FIP replaces libfc's fabric-oriented discovery module with its own simple code that adds remote ports as they are discovered from incoming claim notifications and responses. These hooks are placed by fcoe_disc_init(). A linear list of discovered vn_ports is maintained under the fcoe_ctlr struct. It is expected to be short for now, and accessed infrequently. It is kept under RCU for lock-ordering reasons. The lport and/or rport mutexes may be held when we need to lookup a fcoe_vnport during an ELS send. Change fcoe_ctlr_encaps() to lookup the destination vn_port in the list of peers for the destination MAC address of the FIP-encapsulated frame. Add a new function fcoe_disc_init() to initialize just the discovery portion of libfcoe for VN2VN mode.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-306-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

| | | | | | | | | | | | | | | | | | | | | | | | | Use libfcoe as a common FIP implementation with fcoe. FIP or non-FIP mode is fully automatic if the firmware supports and enables it. Even if FIP is not supported, this uses libfcoe for the non-FIP handling of FLOGI and its response. Use the new lport_set_port_id() notification to capture successful FLOGI responses and port_id resets. While transitioning between Ethernet and FC mode, all rx and tx FC frames are queued. In Ethernet mode, all frames are passed to the exchange manager to capture FLOGI responses. Change to set data_src_addr to the ctl_src_addr whenever it would have previously been zero because we're not logged in. This seems safer so we'll never send a frame with a 0 source MAC. This also eliminates a special case for sending FLOGI frames.

| | | | | | | | | | | | | | | | | | | | | allocation I'd like to keep basic initialization together with allocation, which means this can't just be a tail-call to scsi_host_alloc. This is needed to create a generic libfc host allocation routine for NPIV VN_Ports, which will share the exchange ID space (through sharing exchange manager structures) with the parent lport. In order to clone the exchange manager list when the lport is allocated, the list head must be initialized earlier. Also, update fnic to use the libfc_host_alloc so that later changes do not break it.

* [SCSI] fnic: Allocate OS interrupt resources just before enabling interruptsAbhijeet Joglekar2009-12-041-11/+10
| | | | | | | | | | | | | | | | | | | The OS interrupt vectors were getting allocated before the interrupt resources were mapped from hardware. For Legacy interrupts, since they are shared with other devices, as soon as an interrupt is registered with the OS, it can fire while the fnic isr resource is still unmapped. This can cause crash because of access to unmapped resources. For MSIX and MSI, since interrupts are not shared with other devices, this problem didnt happen, because the interrupt is enabled as the last step before returning from _probe. For Legacy however, since the interrupt is shared, the handler can be called as soon as it is registered. Solution is to register interrupt handlers with OS as last step before enabling device interrupts.

* [SCSI] fnic: Process all cq entries per ISRAbhijeet Joglekar2009-12-041-9/+9
| | | | | | | | | | | | | | | | | | | | | Driver was processing a fixed max number of cq descriptors per ISR. For instance, for the SCSI IO queue, number of IOs processed per ISR were 8. If hardware writes 9 cq descriptors to the cq and generates an interrupt, driver would process only 8 descriptors and decrement the outstanding credit count by 8. Unless another interrupt event happens, the hw does not generate any additional interrupt. This results in the cq descriptor sitting in the queue without being procesed and can cause IO timeouts and aborts. Modify all ISR functions to process all queued cq descriptors in one shot. Since bulk of ELS frame processing is done in thread context and bulk of SCSI IO processing is done in soft ISR deferred context, the cycles spent in the ISR per cq descriptor is small.

* [SCSI] fcoe, fnic, libfc: modifies current code paths to use EM anchor listVasu Dev2009-08-222-12/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modifies current code to use EM anchor list in EM allocation, EM free, EM reset, exch allocation and exch lookup code paths. 1. Modifies fc_exch_mgr_alloc to accept EM match function and then have allocated EM added to the lport using fc_exch_mgr_add API while also updating EM kref for newly added EM. 2. Updates fc_exch_mgr_free API to accept only lport pointer instead EM and then have this API free all EMs of the lport from EM anchor list. 3. Removes single lport pointer link from the EM, which was used in associating lport pointer in newly allocated exchange. Instead have lport pointer passed along new exchange allocation call path and then store passed lport pointer in newly allocated exchange, this will allow a single EM instance to be used across more than one lport and used in EM reset to reset only lport specific exchanges. 4. Modifies fc_exch_mgr_reset to reset all EMs from the EM anchor list of the lport, adds additional exch lport pointer (ep->lp) check for shared EM case to reset exchange specific to a lport requested reset. 5. Updates exch allocation API fc_exch_alloc to use EM anchor list and its anchor match func pointer. The fc_exch_alloc will walk the list of EMs until it finds a match, a match will be either null match func pointer or call to match function returning true value. 6. Updates fc_exch_recv to accept incoming frame on local port using only lport pointer and frame pointer without specifying EM instance of incoming frame. Instead modified fc_exch_recv to locate EM for the incoming frame by matching xid of incoming frame against a EM xid range. This change was required to use EM list in libfc Rx path and after this change the lport fc_exch_mgr pointer emp is not needed anymore, so removed emp pointer. 7. Updates fnic for removed lport emp pointer and above modified libfc APIs fc_exch_recv, fc_exch_mgr_alloc and fc_exch_mgr_free. 8. Removes exch_get and exch_put from libfc_function_template as these are no longer needed with EM anchor list and its match function use. Also removes its default function fc_exch_get.
