Freeing the iova range that is \u003e\u003d the last iova in the\nlower 32bit range when there is still an iova above the 32bit range will\ncorrupt the cached iova by pointing it to a region that is above 32bit.\nIf that region is also larger than the device\u0027s dma mask, a subsequent\nallocation will return an unusable iova and cause dma failure.\n\nSimply don\u0027t cache an iova that is above the 32bit caching boundary.\n\nReported-by: Mike Travis \u003ctravis@sgi.com\u003e\nReported-by: Mike Habeck \u003chabeck@sgi.com\u003e\nCc: stable@kernel.org\nAcked-by: Mike Travis \u003ctravis@sgi.com\u003e\nTested-by: Mike Habeck \u003chabeck@sgi.com\u003e\nSigned-off-by: Chris Wright \u003cchrisw@sous-sol.org\u003e\nSigned-off-by: David Woodhouse \u003cDavid.Woodhouse@intel.com\u003e\n" }, { "commit": "cb452a4040bb051d92e85d6e7eb60c11734c1781", "tree": "ef19298ec70274c9c199fa74a4f08e77cc69080b", "parents": [ "8fcc5372fbac085199d84a880503ed67aba3fe49" ], "author": { "name": "Mike Travis", "email": "travis@sgi.com", "time": "Sat May 28 13:15:03 2011 -0500" }, "committer": { "name": "David Woodhouse", "email": "David.Woodhouse@intel.com", "time": "Wed Jun 01 12:47:36 2011 +0100" }, "message": "intel-iommu: Speed up processing of the identity_mapping function\n\nWhen there are a large count of PCI devices, and the pass through\noption for iommu is set, much time is spent in the identity_mapping\nfunction hunting though the iommu domains to check if a specific\ndevice is \"identity mapped\".\n\nSpeed up the function by checking the cached info to see if\nit\u0027s mapped to the static identity domain.\n\nSigned-off-by: Mike Travis \u003ctravis@sgi.com\u003e\nReviewed-by: Mike Habeck \u003chabeck@sgi.com\u003e\nCc: stable@kernel.org\nSigned-off-by: David Woodhouse \u003cDavid.Woodhouse@intel.com\u003e\n" }, { "commit": "8fcc5372fbac085199d84a880503ed67aba3fe49", "tree": "aab84e5ac18fa8028efa49e2cc47a5b97d873916", "parents": [ "9b4554b21ed07e8556405510638171f0c787742a" ], "author": { "name": "Chris Wright", "email": "chrisw@sous-sol.org", "time": "Sat May 28 13:15:02 2011 -0500" }, "committer": { "name": "David Woodhouse", "email": "David.Woodhouse@intel.com", "time": "Wed Jun 01 12:47:34 2011 +0100" }, "message": "intel-iommu: Check for identity mapping candidate using system dma mask\n\nThe identity mapping code appears to make the assumption that if the\ndevices dma_mask is greater than 32bits the device can use identity\nmapping.

We never have to\nworry about *breaking* superpages, since we trust that we will always\n*unmap* the same range that was mapped.

By calling objlayout_io_set_result() for\neach failing device.\n\nIn objio_osd:\n* Allocate io-error descriptors space as part of io_state\n* Use generic objlayout error reporting at end of io.\n\nSigned-off-by: Boaz Harrosh \u003cbharrosh@panasas.com\u003e\nSigned-off-by: Benny Halevy \u003cbhalevy@panasas.com\u003e\n" }, { "commit": "04a555498e03b3804e2dec916a4669f5f560e503", "tree": "4fab39683df70cee7f7aea7d7718072a811ad153", "parents": [ "8a1636c459cb7a4b32ba4024cd1b2ba21fba6aed" ], "author": { "name": "Andy Adamson", "email": "andros@netapp.com", "time": "Sun May 22 19:53:10 2011 +0300" }, "committer": { "name": "Boaz Harrosh", "email": "bharrosh@panasas.com", "time": "Sun May 29 20:54:37 2011 +0300" }, "message": "pnfs: encode_layoutreturn\n\nAdd a layout driver method to encode the layout type specific\nopaque part of layout return in-line in the xdr stream.\n\nCurrently the pnfs-objects layout driver uses it to encode i/o error\ninformation on LAYOUTRETURN.\n\nSigned-off-by: Andy Adamson \u003candros@netapp.com\u003e\n[fixup layout header pointer for encode_layoutreturn]\nSigned-off-by: Benny Halevy \u003cbhalevy@panasas.com\u003e\n" }, { "commit": "8a1636c459cb7a4b32ba4024cd1b2ba21fba6aed", "tree": "f9c46f272b98ceb65f997f226d47da68c6fcac6b", "parents": [ "cbe8260369c9f88eafa035cd327dc3e02fad528c" ], "author": { "name": "Benny Halevy", "email": "bhalevy@panasas.com", "time": "Wed Jul 14 15:43:57 2010 -0400" }, "committer": { "name": "Boaz Harrosh", "email": "bharrosh@panasas.com", "time": "Sun May 29 20:54:36 2011 +0300" }, "message": "pnfs: layoutret_on_setattr\n\nWith the objects layout security model, we have object capabilities\nthat are associated with the layout and we anticipate that the server\nwill issue a cb_layoutrecall for any setattr that changes security\nrelated attributes (user/group/mode/acl) or truncates the file.\n\nTherefore, the layout is returned before issuing the setattr to avoid\nthe anticipated cb_layoutrecall.\n\nSigned-off-by: Benny Halevy \u003cbhalevy@panasas.com\u003e\n" }, { "commit": "cbe8260369c9f88eafa035cd327dc3e02fad528c", "tree": "13316d9b1a761cf58c35e663375b72f6ac07c5d2", "parents": [ "04f83450388e87d86b387cf4a27b81eb7e69de7d" ], "author": { "name": "Benny Halevy", "email": "bhalevy@panasas.com", "time": "Sun May 22 19:52:37 2011 +0300" }, "committer": { "name": "Boaz Harrosh", "email": "bharrosh@panasas.com", "time": "Sun May 29 20:54:36 2011 +0300" }, "message": "pnfs: layoutreturn\n\nNFSv4.1 LAYOUTRETURN implementation\n\nCurrently, does not support layout-type payload encoding.\n\nSigned-off-by: Alexandros Batsakis \u003cbatsakis@netapp.com\u003e\nSigned-off-by: Andy Adamson \u003candros@citi.umich.edu\u003e\nSigned-off-by: Andy Adamson \u003candros@netapp.com\u003e\nSigned-off-by: Dean Hildebrand \u003cdhildeb@us.ibm.com\u003e\nSigned-off-by: Fred Isaman \u003ciisaman@citi.umich.edu\u003e\nSigned-off-by: Fred Isaman \u003ciisaman@netapp.com\u003e\nSigned-off-by: Marc Eshel \u003ceshel@almaden.ibm.com\u003e\nSigned-off-by: Zhang Jingwang \u003czhangjingwang@nrchpc.ac.cn\u003e\n[call pnfs_return_layout right before pnfs_destroy_layout]\n[remove assert_spin_locked from pnfs_clear_lseg_list]\n[remove wait parameter from the layoutreturn path.]\n[remove return_type field from nfs4_layoutreturn_args]\n[remove range from nfs4_layoutreturn_args]\n[no need to send layoutcommit from _pnfs_return_layout]\n[don\u0027t wait on sync layoutreturn]\n[fix layout stateid in layoutreturn args]\n[fixed NULL deref in _pnfs_return_layout]\n[removed recaim member of nfs4_layoutreturn_args]\nSigned-off-by: Benny Halevy \u003cbhalevy@panasas.com\u003e\n" }, { "commit": "04f83450388e87d86b387cf4a27b81eb7e69de7d", "tree": "99c10d6a995ed1e7b872abb0127fc38d6bef9982", "parents": [ "d20581aa4be11407c9eeeb75992df5ef176bba0f" ], "author": { "name": "Boaz Harrosh", "email": "bharrosh@panasas.com", "time": "Sun May 22 19:52:19 2011 +0300" }, "committer": { "name": "Boaz Harrosh", "email": "bharrosh@panasas.com", "time": "Sun May 29 20:54:15 2011 +0300" }, "message": "pnfs-obj: osd raid engine read/write implementation\n\nWith the use of the in-kernel osd library.
