The hitch here\nis that the -\u003enopage handler didn\u0027t pass down enough information (ie.  pgoff).\n But it is more logical to pass pgoff rather than have the -\u003enopage function\ncalculate it itself anyway (because that\u0027s a similar layering violation).\n\nHaving the populate handler install the pte itself is likewise a nasty thing\nto be doing.\n\nThis patch introduces a new fault handler that replaces -\u003enopage and\n-\u003epopulate and (later) -\u003enopfn.  Most of the old mechanism is still in place\nso there is a lot of duplication and nice cleanups that can be removed if\neveryone switches over.\n\nThe rationale for doing this in the first place is that nonlinear mappings are\nsubject to the pagefault vs invalidate/truncate race too, and it seemed stupid\nto duplicate the synchronisation logic rather than just consolidate the two.\n\nAfter this patch, MAP_NONBLOCK no longer sets up ptes for pages present in\npagecache.

      "message": "mm: fix fault vs invalidate race for linear mappings\n\nFix the race between invalidate_inode_pages and do_no_page.\n\nAndrea Arcangeli identified a subtle race between invalidation of pages from\npagecache with userspace mappings, and do_no_page.\n\nThe issue is that invalidation has to shoot down all mappings to the page,\nbefore it can be discarded from the pagecache.  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"
