Until now, they have\nbeen stored in the subvolume trees, indexed by the inode that is\nreferencing the data block. This means that when we read the inode,\nwe\u0027ve probably read in at least some checksums as well.\n\nBut, this has a few problems:\n\n* The checksums are indexed by logical offset in the file. When\ncompression is on, this means we have to do the expensive checksumming\non the uncompressed data. It would be faster if we could checksum\nthe compressed data instead.\n\n* If we implement encryption, we\u0027ll be checksumming the plain text and\nstoring that on disk. This is significantly less secure.\n\n* For either compression or encryption, we have to get the plain text\nback before we can verify the checksum as correct. This makes the raid\nlayer balancing and extent moving much more expensive.\n\n* It makes the front end caching code more complex, as we have touch\nthe subvolume and inodes as we cache extents.\n\n* There is potentitally one copy of the checksum in each subvolume\nreferencing an extent.\n\nThe solution used here is to store the extent checksums in a dedicated\ntree. This allows us to index the checksums by phyiscal extent\nstart and length. It means:\n\n* The checksum is against the data stored on disk, after any compression\nor encryption is done.\n\n* The checksum is stored in a central location, and can be verified without\nfollowing back references, or reading inodes.\n\nThis makes compression significantly faster by reducing the amount of\ndata that needs to be checksummed. It will also allow much faster\nraid management code in general.\n\nThe checksums are indexed by a key with a fixed objectid (a magic value\nin ctree.h) and offset set to the starting byte of the extent. This\nallows us to copy the checksum items into the fsync log tree directly (or\nany other tree), without having to invent a second format for them.\n\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\n" }, { "commit": "c99e905c945c462085c6d64646dc5af0c0a16815", "tree": "3aed8630c0778c4a8b26a5d8eb2fba42fbb5e26c", "parents": [ "2a7108ad89e1ea9a30afbbece8b581a0532afd12" ], "author": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Tue Dec 02 11:18:37 2008 -0500" }, "committer": { "name": "Chris Mason", "email": "chris.mason@oracle.com", "time": "Tue Dec 02 11:18:37 2008 -0500" }, "message": "Btrfs: Fix sparse endian warnings in struct-funcs.c\n\nThe btrfs macros to access individual struct members on disk were\nsending the same variable to functions that expected different types\nof endianness.

That\u0027s fine if we have a hold on inode; however, for all\nother cases we need to make damn sure we don\u0027t race with umount. We can\n*NOT* just grab a reference to a watch - inotify_unmount_inodes() will\nhappily sail past it and we\u0027ll end with reference to inode potentially\noutliving its superblock.\n\nIdeally we just want to grab an active reference to superblock if we\ncan; that will make sure we won\u0027t go into inotify_umount_inodes() until\nwe are done. Cleanup is just deactivate_super().\n\nHowever, that leaves a messy case - what if we *are* racing with\numount() and active references to superblock can\u0027t be acquired anymore?\nWe can bump -\u003es_count, grab -\u003es_umount, which will almost certainly wait\nuntil the superblock is shut down and the watch in question is pining\nfor fjords. That\u0027s fine, but there is a problem - we might have hit the\nwindow between -\u003es_active getting to 0 / -\u003es_count - below S_BIAS (i.e.\nthe moment when superblock is past the point of no return and is heading\nfor shutdown) and the moment when deactivate_super() acquires\n-\u003es_umount.\n\nWe could just do drop_super() yield() and retry, but that\u0027s rather\nantisocial and this stuff is luser-triggerable. OTOH, having grabbed\n-\u003es_umount and having found that we\u0027d got there first (i.e. that\n-\u003es_root is non-NULL) we know that we won\u0027t race with\ninotify_umount_inodes().\n\nSo we could grab a reference to watch and do the rest as above, just\nwith drop_super() instead of deactivate_super(), right? Wrong. We had\nto drop ih-\u003emutex before we could grab -\u003es_umount. So the watch\ncould\u0027ve been gone already.\n\nThat still can be dealt with - we need to save watch-\u003ewd, do idr_find()\nand compare its result with our pointer. If they match, we either have\nthe damn thing still alive or we\u0027d lost not one but two races at once,\nthe watch had been killed and a new one got created with the same -\u003ewd\nat the same address. That couldn\u0027t have happened in inotify_destroy(),\nbut inotify_rm_wd() could run into that. Still, \"new one got created\"\nis not a problem - we have every right to kill it or leave it alone,\nwhatever\u0027s more convenient.\n\nSo we can use idr_find(...) \u003d\u003d watch \u0026\u0026 watch-\u003einode-\u003ei_sb \u003d\u003d sb as\n\"grab it and kill it\" check. If it\u0027s been our original watch, we are\nfine, if it\u0027s a newcomer - nevermind, just pretend that we\u0027d won the\nrace and kill the fscker anyway; we are safe since we know that its\nsuperblock won\u0027t be going away.\n\nAnd yes, this is far beyond mere \"not very pretty\"; so\u0027s the entire\nconcept of inotify to start with.\n\nSigned-off-by: Al Viro
