An array for\npages is already allocated for us by nfs_readdata_alloc() (and the write\nand commit equivalents).\n\nThis is also required for adding support for vectored I/O to the NFS direct\nI/O path.\n\nThe original reason to pin the user buffer and allocate all the NFS data\nstructures before trying to schedule I/O was to ensure all needed resources\nare allocated on the client before starting to send requests. This reduces\nthe chance that resource exhaustion on the client will cause a short read\nor write.\n\nOn the other hand, for an application making very large application I/O\nrequests, this means that it will be nearly impossible for the application\nto make forward progress on a resource-limited client.\n\nThus, moving the buffer pinning functionality into the I/O scheduling\nloops should be good for scalability. The next patch will do the same for\nNFS data structure allocation.\n\nSigned-off-by: Chuck Lever \u003ccel@netapp.com\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "9c93ab7dff5eb22027ab15010557bb73f9b44c99", "tree": "654a010c2aa161d0f9f49d7137410aaca1ebd2ba", "parents": [ "51a7bc6caec94bab256b272bffd24d00ea81c698" ], "author": { "name": "Chuck Lever", "email": "cel@netapp.com", "time": "Tue Jun 20 12:56:31 2006 -0400" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Sat Jun 24 13:11:39 2006 -0400" }, "message": "NFS: refactor nfs_direct_free_user_pages\n\nClean-up and fix a minor bug: the logic was dirtying page cache pages on\nboth read and write operations.\n\nSigned-off-by: Chuck Lever \u003ccel@netapp.com\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "51a7bc6caec94bab256b272bffd24d00ea81c698", "tree": "29e19b93449e6affb53a737b73ddec847e21cc50", "parents": [ "fedb595c66e1fbd5acafe0d43b7e95c13c936d61" ], "author": { "name": "Chuck Lever", "email": "cel@netapp.com", "time": "Tue Jun 20 12:56:16 2006 -0400" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Sat Jun 24 13:11:39 2006 -0400" }, "message": "NFS: remove user_addr, user_count, and pos from nfs_direct_req\n\nMake the user_addr, user_count, and pos parameters explicit to the\nscheduler routines, and remove the fields from nfs_direct_req.

Any O_DIRECT write to an NFS file where the\nuser buffer starts with a valid mapped page and contains an unmapped page,\nwill crash in this way. I haven\u0027t followed the code, but O_DIRECT reads with\nsimilar user buffers will probably also crash albeit in different ways.\n\nDetails: when nfs_get_user_pages() calls get_user_pages(), it detects and\ncorrectly handles get_user_pages() returning an error, which happens if the\nfirst page covered by the user buffer\u0027s address range is unmapped. However,\nif the first page is mapped but some subsequent page isn\u0027t, get_user_pages()\nwill return a positive number which is less than the number of pages requested\n(this behaviour is sort of analagous to a short write() call and appears to be\nintentional). nfs_get_user_pages() doesn\u0027t detect this and hands off the\narray of pages (whose last few elements are random rubbish from the newly\nallocated array memory) to it\u0027s caller, whence they go to\nnfs_direct_write_seg(), which then totally ignores the nr_pages it\u0027s given,\nand calculates its own idea of how many pages are in the array from the user\nbuffer length. Needless to say, when it comes to transmit those uninitialised\npage* pointers, we see a crash in the network stack.\n\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "1935245655996ca4d14e687c3a100d2e2bbdc78d", "tree": "9b5d286f8c72ce08b3b723ef4f9af76db430894a", "parents": [ "fba3bad488a2eec2d76c067edb7a5ff92ef42431" ], "author": { "name": "Dirk Mueller", "email": "dmueller@suse.com", "time": "Wed Feb 01 12:19:47 2006 -0500" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Wed Feb 01 12:52:25 2006 -0500" }, "message": "NFSv3: fix sync_retry in direct i/o NFS\n\n Only do a sync_retry if the memcmp failed.\n\n Signed-off-by: Dirk Mueller \u003cdmueller@suse.com\u003e\n Signed-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "566dd6064e89b15ff2dec666a421bebf0f98f26c", "tree": "45ccdc3084c56557ba5baeae771be7c1e0564ae5", "parents": [ "70b9ecbdb9c5fdc731f8780bffd45d9519020c4a" ], "author": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Tue Jan 03 09:55:35 2006 +0100" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Fri Jan 06 14:58:50 2006 -0500" }, "message": "NFS: Make directIO aware of compound pages...\n\n ...and avoid calling set_page_dirty on them\n\n Signed-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "40859d7ee64ed6bfad8a4e93f9bb5c1074afadff", "tree": "ed4069423c3d6551035d5b6116f50452cdac4103", "parents": [ "325cfed9ae901320e9234b18c21434b783dbe342" ], "author": { "name": "Chuck Lever", "email": "cel@netapp.com", "time": "Wed Nov 30 18:09:02 2005 -0500" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Fri Jan 06 14:58:49 2006 -0500" }, "message": "NFS: support large reads and writes on the wire\n\n Most NFS server implementations allow up to 64KB reads and writes on the\n wire.
