It allows VN_ports to discover each other\nover a loss-free L2 Ethernet without any FCF or Fibre-channel fabric\nservices. This is point-to-multipoint. There is also a variant\nof this called point-to-point which provides for making sure there\nis just one pair of ports operating over the Ethernet fabric.\n\nWe add these new states: VNMP_START, _PROBE1, _PROBE2, _CLAIM, and _UP.\nThese usually go quickly in that sequence. After waiting a random\namount of time up to 100 ms in START, we select a pseudo-random\nproposed locally-unique port ID and send out probes in states PROBE1\nand PROBE2, 100 ms apart. If no probe responses are heard, we\nproceed to CLAIM state 400 ms later and send a claim notification.\nWe wait another 400 ms to receive claim responses, which give us\na list of the other nodes on the network, including their FC-4\ncapabilities. After another 400 ms we go to VNMP_UP state and\nshould start interoperating with any of the nodes for whic we\nreceivec claim responses. More details are in the spec.j\n\nAdd the new mode as FIP_MODE_VN2VN. The driver must specify\nexplicitly that it wants to operate in this mode. There is\nno automatic detection between point-to-multipoint and fabric\nmode, and the local port initialization is affected, so it isn\u0027t\nanticipated that there will ever be any such automatic switchover.\n\nIt may eventually be possible to have both fabric and VN2VN\nmodes on the same L2 network, which may be done by two separate\nlocal VN_ports (lports).\n\nWhen in VN2VN mode, FIP replaces libfc\u0027s fabric-oriented discovery\nmodule with its own simple code that adds remote ports as they\nare discovered from incoming claim notifications and responses.\nThese hooks are placed by fcoe_disc_init().\n\nA linear list of discovered vn_ports is maintained under the\nfcoe_ctlr struct. It is expected to be short for now, and\naccessed infrequently. It is kept under RCU for lock-ordering\nreasons. The lport and/or rport mutexes may be held when we\nneed to lookup a fcoe_vnport during an ELS send.\n\nChange fcoe_ctlr_encaps() to lookup the destination vn_port in\nthe list of peers for the destination MAC address of the\nFIP-encapsulated frame.\n\nAdd a new function fcoe_disc_init() to initialize just the\ndiscovery portion of libfcoe for VN2VN mode.\n\nSigned-off-by: Joe Eykholt \u003cjeykholt@cisco.com\u003e\nSigned-off-by: Robert Love \u003crobert.w.love@intel.com\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@suse.de\u003e\n" }, { "commit": "3d902ac09a2812b359edf633425d1327a18399e9", "tree": "188605c45a1502862610b03e8429a67ed3d3a7b7", "parents": [ "0685230c59b5482e04ab50e7afc51119ceaba651" ], "author": { "name": "Joe Eykholt", "email": "jeykholt@cisco.com", "time": "Tue Jul 20 15:19:58 2010 -0700" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Wed Jul 28 09:05:52 2010 -0500" }, "message": "[SCSI] libfcoe: fcoe: fnic: change fcoe_ctlr_init interface to specify mode\n\nThere are three modes that libfcoe currently supports, and a new one\nis coming.

Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my\n distributed build env didn\u0027t work with gcov compiles) and a few\n more options had to be turned off depending on archs to make things\n build (like ipr on powerpc/64 which failed due to missing writeq).\n\n * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n * powerpc and powerpc64 SMP allmodconfig\n * sparc and sparc64 SMP allmodconfig\n * ia64 SMP allmodconfig\n * s390 SMP allmodconfig\n * alpha SMP allmodconfig\n * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n" }, { "commit": "f90f50d7c530793c9c705a8f7fa3deb01714f21a", "tree": "b8116aac0f8a72dd55f0b0ec640e3165b485864d", "parents": [ "c693a71d2556128ef0b5b2440f0b579cd42c425d" ], "author": { "name": "Venkata Siva Vijayendra Bhamidipati", "email": "vbhamidi@cisco.com", "time": "Tue Feb 16 12:15:55 2010 -0800" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Wed Feb 17 17:43:54 2010 -0600" }, "message": "[SCSI] fnic: Set fnic driver version\n\nUpdate fnic driver version.\n\nSigned-off-by: Venkata Siva Vijayendra Bhamidipati \u003cvbhamidi@cisco.com\u003e\nSigned-off-by: Robert Love \u003crobert.w.love@intel.com\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@suse.de\u003e\n" }, { "commit": "c693a71d2556128ef0b5b2440f0b579cd42c425d", "tree": "f168a845b4ef7d52adb147ac47f2eda1e420bee8", "parents": [ "aaa5e569ca96f5cf70202679a5864e60798b8ef6" ], "author": { "name": "Venkata Siva Vijayendra Bhamidipati", "email": "vbhamidi@cisco.com", "time": "Tue Feb 16 12:15:50 2010 -0800" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Wed Feb 17 17:43:52 2010 -0600" }, "message": "[SCSI] fnic: lport stats need to be initialized in fnic_probe()\n\nIncorrect initialization of lport stats in fnic_probe() causes fnic to\ncrash at bootup and a node hang if fip is enabled and all links are brought\nup after fnic is loaded.\n\nSigned-off-by: Joe Eykholt \u003cjeykholt@cisco.com\u003e\nSigned-off-by: Venkata Siva Vijayendra Bhamidipati \u003cvbhamidi@cisco.com\u003e\nSigned-off-by: Robert Love \u003crobert.w.love@intel.com\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@suse.de\u003e\n" }, { "commit": "aaa5e569ca96f5cf70202679a5864e60798b8ef6", "tree": "198c37cf6307fd972436e80dc2b9dffdf4606fe8", "parents": [ "e9ee2cf438066aa02df98db959733e1547432983" ], "author": { "name": "Venkata Siva Vijayendra Bhamidipati", "email": "vbhamidi@cisco.com", "time": "Tue Feb 16 12:15:44 2010 -0800" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Wed Feb 17 17:43:49 2010 -0600" }, "message": "[SCSI] fnic: Allow multicast and unicast address registrations for fnic\n\nTo enable FIP support in fnic, we have to register with hardware to receive\nFIP solication frames on a well-known multicast address.\nBefore FIP support, the firmware interface allowed multicast address\nregistrations only for enic devices.

For Legacy however, since the\ninterrupt is shared, the handler can be called as soon as it is registered.\n\nSolution is to register interrupt handlers with OS as last step before\nenabling device interrupts.\n\nSigned-off-by: Abhijeet Joglekar \u003cabjoglek@cisco.com\u003e\nSigned-off-by: Robert Love \u003crobert.w.love@intel.com\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@suse.de\u003e\n" }, { "commit": "65d430fa99cbd0e88d09a3343f697c51fc8a7009", "tree": "d0e7f7353bb227ff7585ff77cc682611acd1680b", "parents": [ "03b147083a2f9a2a3fbbd2505fa88ffa3c6ab194" ], "author": { "name": "Christof Schmitt", "email": "christof.schmitt@de.ibm.com", "time": "Fri Oct 30 17:59:29 2009 +0100" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Fri Dec 04 12:00:52 2009 -0600" }, "message": "[SCSI] scsi_transport_fc: Introduce helper function for blocking scsi_eh\n\nMove the duplicated code from FC LLDs to SCSI FC transport class.\n\nAcked-by: James Smart \u003cjames.smart@emulex.com\u003e\nAcked-by: Giridhar Malavali \u003cgiridhar.malavali@qlogic.com\u003e\nAcked-by: Abhijeet Joglekar \u003cabjoglek@cisco.com\u003e\nSigned-off-by: Christof Schmitt \u003cchristof.schmitt@de.ibm.com\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@suse.de\u003e\n" }, { "commit": "4b53662bd594941e5e5e540baaaff6a3e66d062c", "tree": "934e76d1254c90af5017e6454718e847217c14ad", "parents": [ "f9bdc3da4c9c2af4886bc6a562effc05cbf75234" ], "author": { "name": "Abhijeet Joglekar", "email": "abjoglek@cisco.com", "time": "Wed Oct 21 16:28:25 2009 -0700" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Fri Dec 04 12:00:36 2009 -0600" }, "message": "[SCSI] fnic: Pad the unused bytes of CDB to 0s\n\nSigned-off-by: Abhijeet Joglekar \u003cabjoglek@cisco.com\u003e\nSigned-off-by: Robert Love \u003crobert.w.love@intel.com\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@suse.de\u003e\n" }, { "commit": "f9bdc3da4c9c2af4886bc6a562effc05cbf75234", "tree": "3aea57eeee1f43905dabec0a7c1194f7be5935c8", "parents": [ "d5cf4b28e13989ace24cf26de1e1debec18e9685" ], "author": { "name": "Abhijeet Joglekar", "email": "abjoglek@cisco.com", "time": "Wed Oct 21 16:28:19 2009 -0700" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Fri Dec 04 12:00:35 2009 -0600" }, "message": "[SCSI] fnic: Set max_cmd_len to driver supported CDB length\n\nSigned-off-by: Abhijeet Joglekar \u003cabjoglek@cisco.com\u003e\nSigned-off-by: Robert Love \u003crobert.w.love@intel.com\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@suse.de\u003e\n" }, { "commit": "d5cf4b28e13989ace24cf26de1e1debec18e9685", "tree": "f1b5ad05036ef81a5ab1c16d25d6484dadb73d13", "parents": [ "8f550f937e9fdafa5c37e348e214aecec851ef3f" ], "author": { "name": "Abhijeet Joglekar", "email": "abjoglek@cisco.com", "time": "Wed Oct 21 16:28:14 2009 -0700" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Fri Dec 04 12:00:35 2009 -0600" }, "message": "[SCSI] fnic: Process all cq entries per ISR\n\nDriver was processing a fixed max number of cq descriptors per ISR.

Modifies fc_exch_mgr_alloc to accept EM match function and then\n have allocated EM added to the lport using fc_exch_mgr_add API\n while also updating EM kref for newly added EM.\n\n 2. Updates fc_exch_mgr_free API to accept only lport pointer instead\n EM and then have this API free all EMs of the lport from EM anchor\n list.\n\n 3. Removes single lport pointer link from the EM, which was used in\n associating lport pointer in newly allocated exchange. Instead have\n lport pointer passed along new exchange allocation call path and\n then store passed lport pointer in newly allocated exchange, this\n will allow a single EM instance to be used across more than one\n lport and used in EM reset to reset only lport specific exchanges.\n\n 4. Modifies fc_exch_mgr_reset to reset all EMs from the EM anchor list\n of the lport, adds additional exch lport pointer (ep-\u003elp) check for\n shared EM case to reset exchange specific to a lport requested reset.\n\n 5. Updates exch allocation API fc_exch_alloc to use EM anchor list and\n its anchor match func pointer. The fc_exch_alloc will walk the list\n of EMs until it finds a match, a match will be either null match\n func pointer or call to match function returning true value.\n\n 6. Updates fc_exch_recv to accept incoming frame on local port using\n only lport pointer and frame pointer without specifying EM instance\n of incoming frame. Instead modified fc_exch_recv to locate EM for the\n incoming frame by matching xid of incoming frame against a EM xid range.\n This change was required to use EM list in libfc Rx path and after this\n change the lport fc_exch_mgr pointer emp is not needed anymore, so\n removed emp pointer.\n\n 7. Updates fnic for removed lport emp pointer and above modified libfc APIs\n fc_exch_recv, fc_exch_mgr_alloc and fc_exch_mgr_free.\n\n 8.
