"[SCSI] fcoe: fix a circular locking issue with rtnl and sysfs mutex\n\nCurrently rtnl mutex is grabbed during fcoe create, destroy, enable\nand disable operations while sysfs s_active read mutex is already\nheld, but simultaneously other networking events could try grabbing\nwrite s_active mutex while rtnl is already held and that is causing\ncircular lock warning, its detailed log pasted at end.\n\nIn this log, the rtnl was held before write s_active during device\nrenaming but there are more such cases as Joe reported another\ninstance with tg3 open at:-\nhttp://www.open-fcoe.org/pipermail/devel/2010-February/008263.html\n\nThis patch fixes this issue by not waiting for rtnl mutex during\nfcoe ops, that means if rtnl mutex is not immediately available\nthen restart_syscall() to allow others waiting in line to\ngrab s_active along with rtnl mutex to finish their work first\nunder these mutex.\n\nCurrently rtnl mutex was grabbed twice during fcoe_destroy call flow,\nsecond grab was from fcoe_if_destroy called from fcoe_destroy after\ndropping rtnl mutex before calling fcoe_if_destroy, so instead made\nfcoe_if_destroy always called with rtnl mutex held to have this mutex\ngrabbed only once in this code path.\n\nHowever left matching rtnl_unlock as-is in its original place as it was\ndropped there for good reason since very next call causes synchronous\nfip worker flush and if rtnl mutex is still held before flush\nthen that would cause new circular warning between fip-\u003erecv_work and\nrtnl mutex, I\u0027ve added detailed comment for this on fcoe_if_destroy\ncalling and rtnl muxtes

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": "6409ea65b3b81ef693cbbc7c4b2300e50a4219dd", "tree": "78d71cc32541bd76fbe88b4f5923b9b7ad032205", "parents": [ "f47dd855d9e64a5d499a93e858a82bc5e7b21345" ], "author": { "name": "Rob Love", "email": "robert.w.love@intel.com", "time": "Thu Jan 21 10:16:05 2010 -0800" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Wed Feb 17 09:57:05 2010 -0600" }, "message": "[SCSI] fcoe: Only rmmod fcoe.ko if there are no active connections\n\nCurrently we\u0027re gracefully tearing down each active connection\nwhen fcoe.ko is removed.

But, it\u0027s using \u003e PAGE_SIZE compound pages\nas a single skb_frag. In the highmem linearize case that page will be\npassed to kmap_atomic to get a mapping to copy out of, but\nkmap_atomic will only allow access to the first PAGE_SIZE part.\nThe memcpy will keep going and cause a page fault once is crosses the\nfirst boundary.\n\nIf fc_fcp_send_data uses linear buffers from the start, it calls\nkmap_atomic one PAGE_SIZE at a time. That same logic needs to be\napplied when setting up skb_frags.\n\nSigned-off-by: Chris Leech \u003cchristopher.leech@intel.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": "cc0136c2e9c10e889cb36e39710c0eb10707b396", "tree": "b486a0e899ee7d06365f3efbe1e08c876b91b422", "parents": [ "349e11faa84ebdd6e484572cfe66f2cf4cb483a1" ], "author": { "name": "Yi Zou", "email": "yi.zou@intel.com", "time": "Tue Nov 03 11:49:59 2009 -0800" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Fri Dec 04 12:01:24 2009 -0600" }, "message": "[SCSI] fcoe: Fix using VLAN ID in creating lport\u0027s WWWN/WWPN\n\nIf the underlying netdev is a VLAN device, make sure the VLAN ID is integrated\ninto the WWNN/WWPN name generation.

Currently an EM instance is shared across all cpus to manage\n all exches for all cpus. This required em_lock across all\n cpus for an exch alloc, free, lookup and reset each frame\n and that made em_lock expensive, so instead having per cpu\n exch pool with their own per cpu pool lock will likely reduce\n locking contention in fast path for an exch alloc, free and\n lookup.\n\n 2. Per cpu exch pool will likely improve cache hit ratio since\n all frames of an exch will be processed on the same cpu on\n which exch originated.\n\nThis patch is only prep work to help in keeping complexity of next\npatch low, so this patch only sets up per cpu exch pool and related\nhelper funcs to be used by next patch. The next patch fully makes\nuse of per cpu exch pool in all code paths ie. tx, rx and reset.\n\nDivides per EM exch id range equally across all cpus to setup per\ncpu exch pool. This division is such that lower bits of exch id\ncarries cpu number info on which exch originated, later a simple\nbitwise AND operation on exch id of incoming frame with fc_cpu_mask\nretrieves cpu number info to direct all frames to same cpu on which\nexch originated. This required a global fc_cpu_mask and fc_cpu_order\ninitialized to max possible cpus number nr_cpu_ids rounded up to 2\u0027s\npower, this will be used in mapping exch id and exch ptr array\nindex in pool during exch allocation, find or reset code paths.\n\nAdds a check in fc_exch_mgr_alloc() to ensure specified min_xid\nlower bits are zero since these bits are used to carry cpu info.\n\nAdds and initializes struct fc_exch_pool with all required fields\nto manage exches in pool.\n\nAllocates per cpu struct fc_exch_pool with memory for exches array\nfor range of exches per pool.
