Between shooting down ptes to\na particular page, and actually dropping the struct page from the pagecache,\ndo_no_page from any process might fault on that page and establish a new\nmapping to the page just before it gets discarded from the pagecache.\n\nThe most common case where such invalidation is used is in file truncation.\nThis case was catered for by doing a sort of open-coded seqlock between the\nfile\u0027s i_size, and its truncate_count.\n\nTruncation will decrease i_size, then increment truncate_count before\nunmapping userspace pages; do_no_page will read truncate_count, then find the\npage if it is within i_size, and then check truncate_count under the page\ntable lock and back out and retry if it had subsequently been changed (ptl\nwill serialise against unmapping, and ensure a potentially updated\ntruncate_count is actually visible).\n\nComplexity and documentation issues aside, the locking protocol fails in the\ncase where we would like to invalidate pagecache inside i_size. do_no_page\ncan come in anytime and filemap_nopage is not aware of the invalidation in\nprogress (as it is when it is outside i_size). The end result is that\ndangling (-\u003emapping \u003d\u003d NULL) pages that appear to be from a particular file\nmay be mapped into userspace with nonsense data. Valid mappings to the same\nplace will see a different page.\n\nAndrea implemented two working fixes, one using a real seqlock, another using\na page-\u003eflags bit. He also proposed using the page lock in do_no_page, but\nthat was initially considered too heavyweight. However, it is not a global or\nper-file lock, and the page cacheline is modified in do_no_page to increment\n_count and _mapcount anyway, so a further modification should not be a large\nperformance hit. Scalability is not an issue.\n\nThis patch implements this latter approach. -\u003enopage implementations return\nwith the page locked if it is possible for their underlying file to be\ninvalidated (in that case, they must set a special vm_flags bit to indicate\nso). do_no_page only unlocks the page after setting up the mapping\ncompletely. invalidation is excluded because it holds the page lock during\ninvalidation of each page (and ensures that the page is not mapped while\nholding the lock).\n\nThis also allows significant simplifications in do_no_page, because we have\nthe page locked in the right place in the pagecache from the start.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "c32676eea19ce29cb74dba0f97b085e83f6b8915", "tree": "5eddf206e10b0b1857c899fd9939c517aa758359", "parents": [ "91ebecc74eeeeea0a2aa50bf1964ec2214a229c9" ], "author": { "name": "David Chinner", "email": "dgc@sgi.com", "time": "Thu Jul 19 16:28:58 2007 +1000" }, "committer": { "name": "Tim Shimmin", "email": "tes@chook.melbourne.sgi.com", "time": "Thu Jul 19 19:52:05 2007 +1000" }, "message": "[XFS] Fix inode size update before data write in xfs_setattr\n\nWhen changing the file size by a truncate() call, we log the change in the\ninode size.

When\ndealing with uncompressed realtime HD video streams in this format, it is\ncrucial that files do not get fragmented and that multiple files a placed\ncontiguously on disk.\n\nWhen multiple streams are being ingested and played out at the same time,\nit is critical that the filesystem does not cross the streams and\ninterleave them together as this creates seek and readahead cache miss\nlatency and prevents both ingest and playout from meeting frame rate\ntargets.\n\nThis patch set creates a \"stream of files\" concept into the allocator to\nplace all the data from a single stream contiguously on disk so that RAID\narray readahead can be used effectively. Each additional stream gets\nplaced in different allocation groups within the filesystem, thereby\nensuring that we don\u0027t cross any streams. When an AG fills up, we select a\nnew AG for the stream that is not in use.\n\nThe core of the functionality is the stream tracking - each inode that we\ncreate in a directory needs to be associated with the directories\u0027 stream.\nHence every time we create a file, we look up the directories\u0027 stream\nobject and associate the new file with that object.\n\nOnce we have a stream object for a file, we use the AG that the stream\nobject point to for allocations. If we can\u0027t allocate in that AG (e.g. it\nis full) we move the entire stream to another AG. Other inodes in the same\nstream are moved to the new AG on their next allocation (i.e. lazy\nupdate).\n\nStream objects are kept in a cache and hold a reference on the inode.\nHence the inode cannot be reclaimed while there is an outstanding stream\nreference. This means that on unlink we need to remove the stream\nassociation and we also need to flush all the associations on certain\nevents that want to reclaim all unreferenced inodes (e.g. filesystem\nfreeze).\n\nSGI-PV: 964469\nSGI-Modid: xfs-linux-melb:xfs-kern:29096a\n\nSigned-off-by: David Chinner \u003cdgc@sgi.com\u003e\nSigned-off-by: Barry Naujok \u003cbnaujok@sgi.com\u003e\nSigned-off-by: Donald Douwsma \u003cdonaldd@sgi.com\u003e\nSigned-off-by: Christoph Hellwig \u003chch@infradead.org\u003e\nSigned-off-by: Tim Shimmin \u003ctes@sgi.com\u003e\nSigned-off-by: Vlad Apostolov \u003cvapo@sgi.com\u003e\n" }, { "commit": "0892ccd6fe13e08ad9e57007afbb78fe02d66005", "tree": "ea9ee48df07cd725e4aa6ecc05fd66aad5b76c8f", "parents": [ "fbf3ce8d8ec508f6bd99b36de034d2ae3e1ae7ac" ], "author": { "name": "Andrew Morton", "email": "akpm@linux-foundation.org", "time": "Thu Jun 28 16:46:56 2007 +1000" }, "committer": { "name": "Tim Shimmin", "email": "tes@chook.melbourne.sgi.com", "time": "Sat Jul 14 15:40:02 2007 +1000" }, "message": "[XFS] Use uninitialized_var macro to stop warning about rtx\n\nAppease gcc in regards to \"warning: \u0027rtx\u0027 is used uninitialized in\nthis function\".\n\nSGI-PV: 907752\nSGI-Modid: xfs-linux-melb:xfs-kern:29007a\n\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Tim Shimmin \u003ctes@sgi.com\u003e\n" }, { "commit": "fbf3ce8d8ec508f6bd99b36de034d2ae3e1ae7ac", "tree": "5b10e8948c422b85f7e19da711d2b4d5c9b5e244", "parents": [ "16a087d8e1af9b974125870dceb9e4a35249ad1d" ], "author": { "name": "Christoph Hellwig", "email": "hch@infradead.org", "time": "Thu Jun 28 16:46:47 2007 +1000" }, "committer": { "name": "Tim Shimmin", "email": "tes@chook.melbourne.sgi.com", "time": "Sat Jul 14 15:37:37 2007 +1000" }, "message": "[XFS] XFS should not be looking at filp reference counts\n\nA check for file_count is always a bad idea.

The buffer then remains locked\nuntil the transaction is committed into the incore log buffer. The result\nof this is that with enough transactions on the fly the incore superblock\nbuffer becomes a bottleneck.\n\nThe result of contention on the incore superblock buffer is that\ntransaction rates fall - the more pressure that is put on the superblock\nbuffer, the slower things go.\n\nThe key to removing the contention is to not require the superblock fields\nin question to be locked. We do that by not marking the superblock dirty\nin the transaction. IOWs, we modify the incore superblock but do not\nmodify the cached superblock buffer. In short, we do not log superblock\nmodifications to critical fields in the superblock on every transaction.\nIn fact we only do it just before we write the superblock to disk every\nsync period or just before unmount.\n\nThis creates an interesting problem - if we don\u0027t log or write out the\nfields in every transaction, then how do the values get recovered after a\ncrash? the answer is simple - we keep enough duplicate, logged information\nin other structures that we can reconstruct the correct count after log\nrecovery has been performed.\n\nIt is the AGF and AGI structures that contain the duplicate information;\nafter recovery, we walk every AGI and AGF and sum their individual\ncounters to get the correct value, and we do a transaction into the log to\ncorrect them. An optimisation of this is that if we have a clean unmount\nrecord, we know the value in the superblock is correct, so we can avoid\nthe summation walk under normal conditions and so mount/recovery times do\nnot change under normal operation.\n\nOne wrinkle that was discovered during development was that the blocks\nused in the freespace btrees are never accounted for in the AGF counters.\nThis was once a valid optimisation to make; when the filesystem is full,\nthe free space btrees are empty and consume no space. Hence when it\nmatters, the \"accounting\" is correct. But that means the when we do the\nAGF summations, we would not have a correct count and xfs_check would\ncomplain. Hence a new counter was added to track the number of blocks used\nby the free space btrees. This is an *on-disk format change*.\n\nAs a result of this, lazy superblock counters are a mkfs option and at the\nmoment on linux there is no way to convert an old filesystem. This is\npossible - xfs_db can be used to twiddle the right bits and then\nxfs_repair will do the format conversion for you. Similarly, you can\nconvert backwards as well. At some point we\u0027ll add functionality to\nxfs_admin to do the bit twiddling easily....\n\nSGI-PV: 964999\nSGI-Modid: xfs-linux-melb:xfs-kern:28652a\n\nSigned-off-by: David Chinner \u003cdgc@sgi.com\u003e\nSigned-off-by: Christoph Hellwig \u003chch@infradead.org\u003e\nSigned-off-by: Tim Shimmin \u003ctes@sgi.com\u003e\n" }, { "commit": "3260f78ad6d5b788e78ea709d377f58e569bee41", "tree": "9ba46ac087769061b0cc3f0fec67be863c4a28b7", "parents": [ "92dfe8d266eaf35a50607a0e0dcf525e1d367c80" ], "author": { "name": "Andrew Morton", "email": "akpm@linux-foundation.org", "time": "Thu May 24 15:25:42 2007 +1000" }, "committer": { "name": "Tim Shimmin", "email": "tes@chook.melbourne.sgi.com", "time": "Sat Jul 14 15:23:53 2007 +1000" }, "message": "[XFS] Use generic shrinker interfaces in XFS.\n\nSGI-PV: 964986\nSGI-Modid: xfs-linux-melb:xfs-kern:28642a\n\nSigned-Off-By: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: David Chinner \u003cdgc@sgi.com\u003e\nSigned-off-by: Tim Shimmin \u003ctes@sgi.com\u003e\n" }, { "commit": "92dfe8d266eaf35a50607a0e0dcf525e1d367c80", "tree": "a9149b1bcad2142b14b8b25c06c64a0ae7399f64", "parents": [ "511105b3d7c2440ee84fc3f90d200569aac88162" ], "author": { "name": "David Chinner", "email": "dgc@sgi.com", "time": "Thu May 24 15:22:19 2007 +1000" }, "committer": { "name": "Tim Shimmin", "email": "tes@chook.melbourne.sgi.com", "time": "Sat Jul 14 15:23:40 2007 +1000" }, "message": "[XFS] Make hole punching at EOF atomic.\n\nIf hole punching at EOF is done as two steps (i.e. truncate then extend)\nthe file is in a transient state between the two steps where an\napplication can see the incorrect file size.

Without the fix the update\nof a file\u0027s size, as a result of a write beyond eof, is independent of\nwhen the cached data is flushed to disk. Often the file size update would\nbe written to the filesystem log before the data is flushed to disk. When\na system crashes between these two events and the filesystem log is\nreplayed on mount the file\u0027s size will be set but since the contents never\nmade it to disk the file is full of holes. If some of the cached data was\nflushed to disk then it may just be a section of the file at the end that\nhas holes.\n\nThere are existing fixes to help alleviate this problem, particularly in\nthe case where a file has been truncated, that force cached data to be\nflushed to disk when the file is closed. If the system crashes while the\nfile(s) are still open then this flushing will never occur.\n\nThe fix that we have implemented is to introduce a second file size,\ncalled the in-memory file size, that represents the current file size as\nviewed by the user. The existing file size, called the on-disk file size,\nis the one that get\u0027s written to the filesystem log and we only update it\nwhen it is safe to do so. When we write to a file beyond eof we only\nupdate the in- memory file size in the write operation. Later when the I/O\noperation, that flushes the cached data to disk completes, an I/O\ncompletion routine will update the on-disk file size. The on-disk file\nsize will be updated to the maximum offset of the I/O or to the value of\nthe in-memory file size if the I/O includes eof.\n\nSGI-PV: 958522\nSGI-Modid: xfs-linux-melb:xfs-kern:28322a\n\nSigned-off-by: Lachlan McIlroy \u003clachlan@sgi.com\u003e\nSigned-off-by: David Chinner \u003cdgc@sgi.com\u003e\nSigned-off-by: Tim Shimmin \u003ctes@sgi.com\u003e\n" }, { "commit": "2a32963130aec5e157b58ff7dfa3dfa1afdf7ca1", "tree": "97b38a1d7c69bad94fafeee75102a0701c44f27e", "parents": [ "e6d29426bc8a5d07d0eebd0842fe0cf6ecc862cd" ], "author": { "name": "Lachlan McIlroy", "email": "lachlan@sgi.com", "time": "Tue May 08 13:49:39 2007 +1000" }, "committer": { "name": "Tim Shimmin", "email": "tes@sgi.com", "time": "Tue May 08 13:49:39 2007 +1000" }, "message": "[XFS] Fix race condition in xfs_write().\n\nThis change addresses a race in xfs_write() where, for direct I/O, the\nflags need_i_mutex and need_flush are setup before the iolock is acquired.\nThe logic used to setup the flags may change between setting the flags and\nacquiring the iolock resulting in these flags having incorrect values.
