The timerfd code is new in 2.6.22 and if we merge this\ninto 2.6.23 then we should also merge it into 2.6.22.x. That will leave a few\nearly 2.6.22 kernels out in the wild which might misbehave when a future\ntimerfd-enabled glibc is run on them.\n\nmtk says: The difference would be that read() will only return 4 bytes, while\nthe application will expect 8. If the application is checking the size of\nreturned value, as it should, then it will be able to detect the problem (it\ncould even be sophisticated enough to know that if this is a 4-byte return,\nthen it is running on an old 2.6.22 kernel). If the application is not\nchecking the return from read(), then its 8-byte buffer will not be filled --\nthe contents of the last 4 bytes will be undefined, so the u64 value as a\nwhole will be

frequently need to lookup paths or\npath components starting from an arbitrary point in the namespace\n(identified by a dentry and a vfsmount). Currently, such file systems use\nlookup_one_len, which is frowned upon [1] as it does not pass the lookup\nintent along; not passing a lookup intent, for example, can trigger BUG_ON\u0027s\nwhen stacking on top of NFSv4.\n\nThe first patch introduces a new lookup function to allow lookup starting\nfrom an arbitrary point in the namespace. This approach has been suggested\nby Christoph Hellwig [2].\n\nThe second patch changes sunrpc to use vfs_path_lookup.\n\nThe third patch changes nfsctl.c to use vfs_path_lookup.\n\nThe fourth patch marks link_path_walk static.\n\nThe fifth, and last patch, unexports path_walk because it is no longer\nunnecessary to call it directly, and using the new vfs_path_lookup is\ncleaner.\n\nFor example, the following snippet of code, looks up \"some/path/component\"\nin a directory pointed to by parent_{dentry,vfsmnt}:\n\nerr \u003d vfs_path_lookup(parent_dentry, parent_vfsmnt,\n\t\t \"some/path/component\", 0, \u0026nd);\nif (!err) {\n\t/* exits */\n\n\t...\n\n\t/* once done, release the references */\n\tpath_release(\u0026nd);\n} else if (err \u003d\u003d -ENOENT) {\n\t/* doesn\u0027t exist */\n} else {\n\t/* other error */\n}\n\nVFS functions such as lookup_create can be used on the nameidata structure\nto pass the create intent to the file system.\n\nSigned-off-by: Josef \u0027Jeff\u0027 Sipek \u003cjsipek@cs.sunysb.edu\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nAcked-by: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nCc: Neil Brown \u003cneilb@suse.de\u003e\nCc: Michael Halcrow \u003cmhalcrow@us.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "b6a2fea39318e43fee84fa7b0b90d68bed92d2ba", "tree": "c9c3619cb2730b5c10c7427b837146bce3d69156", "parents": [ "bdf4c48af20a3b0f01671799ace345e3d49576da" ], "author": { "name": "Ollie Wild", "email": "aaw@google.com", "time": "Thu Jul 19 01:48:16 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Thu Jul 19 10:04:45 2007 -0700" }, "message": "mm: variable length argument support\n\nRemove the arg+env limit of MAX_ARG_PAGES by copying the strings directly from\nthe old mm into the new mm.\n\nWe create the new mm before the binfmt code runs, and place the new stack at\nthe very top of the address space.

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.
