The code walks down the tree\nsetting tags before it has fully resolved the path to the leaf under\nthe assumption there will be a leaf slot with the tag set in the\nrange it is searching.\n\nUnfortunately, this is not a valid assumption - we can abort after\nsetting a tag on an intermediate node if we overrun the number of\ntags we are allowed to set in a batch, or stop scanning because we\nwe have passed the last scan index before we reach a leaf slot with\nthe tag we are searching for set.\n\nAs a result, we can leave the function with tags set on intemediate\nnodes which can be tripped over later by tag-based lookups. The\nresult of these stale tags is that lookup may end prematurely or\nlivelock because the lookup cannot make progress.\n\nThe fix for the problem involves reocrding the traversal path we\ntake to the leaf nodes, and only propagating the tags back up the\ntree once the tag is set in the leaf node slot. We are already\nrecording the path for efficient traversal, so there is no\nadditional overhead to do the intermediately node tag setting in\nthis manner.\n\nThis fixes a radix tree lookup livelock triggered by the new\nwriteback sync livelock avoidance code introduced in commit\nf446daaea9d4a420d16c606f755f3689dcb2d0ce (\"mm: implement writeback\nlivelock avoidance using page tagging\").\n\nSigned-off-by: Dave Chinner \u003cdchinner@redhat.com\u003e\nAcked-by: Jan Kara \u003cjack@suse.cz\u003e\n" }, { "commit": "b6dd08652e2b70e73661c4975ae46398066c06f8", "tree": "fa70f295a5074627a6b6dba11a8c8cf90d4e4b95", "parents": [ "da5cabf80e2433131bf0ed8993abc0f7ea618c73" ], "author": { "name": "Dave Chinner", "email": "dchinner@redhat.com", "time": "Mon Aug 23 10:33:19 2010 +1000" }, "committer": { "name": "Dave Chinner", "email": "david@fromorbit.com", "time": "Mon Aug 23 10:33:19 2010 +1000" }, "message": "radix-tree: clear all tags in radix_tree_node_rcu_free\n\nCommit f446daaea9d4a420d16c606f755f3689dcb2d0ce (\"mm: implement\nwriteback livelock avoidance using page tagging\") introduced a new\nradix tree tag, increasing the number of tags in each node from 2 to\n3.

Another is the Wii DMA - used to\nimplement the MEM2 DMA facility needed by its EHCI controller (for details:\nhttp://lkml.org/lkml/2010/5/18/303)\n\nOn bare-metal SWIOTLB is used when there are no hardware IOMMU. In virtualized\nenvironment it used when PCI pass-through is enabled for the guest. The problems\nwith PCI pass-through is that the guest\u0027s idea of PFN\u0027s is not the real thing.\nTo fix that, there is translation layer for PFN-\u003emachine frame number and vice-versa.\nTo bubble that up to the SWIOTLB layer there are two possible solutions.\n\nOne solution has been to wholesale copy the SWIOTLB, stick it in\narch/x86/xen/swiotlb.c and modify the virt_to_phys, phys_to_virt and others\nto use the Xen address translation functions. Unfortunately, since the kernel can\nrun on bare-metal, there would be big code overlap with the real SWIOTLB.\n(git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git xen/dom0/swiotlb-new)\n\nAnother approach, which this set of patches explores, is to abstract the\naddress translation and address determination functions away from the\nSWIOTLB book-keeping functions. This way the core SWIOTLB library functions\nare present in one place, while the address related functions are in\na separate library that can be loaded when running under non-bare-metal platform.\n\nChangelog:\nSince the last posting [v8.2] Konrad has done:\n - Added this changelog in the patch and referenced in the other patches\n this description.\n - \u0027enum dma_data_direction direction\u0027 to \u0027enum dma.. dir\u0027 so to be\n unified.\n[v8-v8.2 changes:]\n - Rolled-up the last two patches in one.\n - Rebased against linus latest.

This is due to stepping back too many levels during\nbacktracking. For simplicity let\u0027s assume that IDR_BITS\u003d1 -\u003e we have 2\nnodes at each level below the root node and each leaf node stores two IDs.\n (In reality for 32 bit systems IDR_BITS\u003d5, with 32 nodes at each sub-root\nlevel and 32 IDs in each leaf node). The sequence of freeing the nodes at\nthe moment is as follows:\n\nlayer\n1 -\u003e a(7)\n2 -\u003e b(3) c(5)\n3 -\u003e d(1) e(2) f(4) g(6)\n\nUntil step 4 things go fine, but then node c is freed, whereas node g\nshould be freed first. Since node c contains the pointer to node g we\u0027ll\nhave a use after free error at step 6.\n\nHow many levels we step back after visiting the leaf nodes is currently\ndetermined by the msb of the id we are currently visiting:\n\nStep\n1. node d with IDs 0,1 is freed, current ID is advanced to 2.\n msb of the current ID bit 1. This means we need to step back\n 1 level to node b and take the next sibling, node e.\n2-3. node e with IDs 2,3 is freed, current ID is 4, msb is bit 2.\n This means we need to step back 2 levels to node a, freeing\n node b on the way.\n4-5. node f with IDs 4,5 is freed, current ID is 6, msb is still\n bit 2. This means we again need to step back 2 levels to node\n a and free c on the way.\n6. We should visit node g, but its pointer is not available as\n node c was freed.\n\nThe fix changes how we determine the number of levels to step back.\nInstead of deducting this merely from the msb of the current ID, we should\nreally check if advancing the ID causes an overflow to a bit position\ncorresponding to a given layer. In the above example overflow from bit 0\nto bit 1 should mean stepping back 1 level. Overflow from bit 1 to bit 2\nshould mean stepping back 2 levels and so on.\n\nThe fix was tested with IDs up to 1 \u003c\u003c 20, which corresponds to 4 layers\non 32 bit systems.\n\nSigned-off-by: Imre Deak \u003cimre.deak@nokia.com\u003e\nReviewed-by: Tejun Heo \u003ctj@kernel.org\u003e\nCc: Eric Paris \u003ceparis@redhat.com\u003e\nCc: \"Paul E.
