They are required\nbecause some filesystems have intrinsic 64-bit inode numbers: NFS3+ and XFS\nfor example. The 64-bit inode numbers are then propagated to userspace\nautomatically where the arch supports it.\n\nProblems have been seen with userspace (eg: ld.so) using the 64-bit inode\nnumber returned by stat64() or getdents64() to differentiate files, and\nfailing because the 64-bit inode number space was compressed to 32-bits, and\nso overlaps occur.\n\nThis patch:\n\nMake filldir_t take a 64-bit inode number and struct kstat carry a 64-bit\ninode number so that 64-bit inode numbers can be passed back to userspace.\n\nThe stat functions then returns the full 64-bit inode number where\navailable and where possible. If it is not possible to represent the inode\nnumber supplied by the filesystem in the field provided by userspace, then\nerror EOVERFLOW will be issued.\n\nSimilarly, the getdents/readdir functions now pass the full 64-bit inode\nnumber to userspace where possible, returning EOVERFLOW instead when a\ndirectory entry is encountered that can\u0027t be properly represented.\n\nNote that this means that some inodes will not be stat\u0027able on a 32-bit\nsystem with old libraries where they were before - but it does mean that\nthere will be no ambiguity over what a 32-bit inode number refers to.\n\nNote similarly that directory scans may be cut short with an error on a\n32-bit system with old libraries where the scan would work before for the\nsame reasons.\n\nIt is judged unlikely that this situation will occur because modern glibc\nuses 64-bit capable versions of stat and getdents class functions\nexclusively, and that older systems are unlikely to encounter\nunrepresentable inode numbers anyway.\n\n[akpm: alpha build fix]\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "128e5ebaf8abbda375bba82690b09630003c9213", "tree": "8c8dcf1f0f8f04a9c56dd2e9378dac1a5a3e4e5c", "parents": [ "d00223f1693173c7b51f867dd52049955a92d0ed" ], "author": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Mon Oct 02 11:24:43 2006 -0400" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Mon Oct 02 11:24:43 2006 -0400" }, "message": "[GFS2] Remove iflags.h, use FS_\n\nUpdate GFS2 in the light of David Howells\u0027 patch:\n\n[PATCH] BLOCK: Move common FS-specific ioctls to linux/fs.h [try #6]\n36695673b012096228ebdc1b39a6a5850daa474e\n\nwhich calls the filesystem independant flags FS_..._FL.

Some drivers that use SCSI facilities -\n \t such as USB storage - end up disabled indirectly from this.\n\n (*) Various block-based device drivers, such as IDE and the old CDROM\n \t drivers.\n\n (*) MTD blockdev handling and FTL.\n\n (*) JFFS - which uses set_bdev_super(), something it could avoid doing by\n \t taking a leaf out of JFFS2\u0027s book.\n\n (*) Makes most of the contents of linux/blkdev.h, linux/buffer_head.h and\n linux/elevator.h contingent on CONFIG_BLOCK being set. sector_div() is,\n however, still used in places, and so is still available.\n\n (*) Also made contingent are the contents of linux/mpage.h, linux/genhd.h and\n parts of linux/fs.h.\n\n (*) Makes a number of files in fs/ contingent on CONFIG_BLOCK.\n\n (*) Makes mm/bounce.c (bounce buffering) contingent on CONFIG_BLOCK.\n\n (*) set_page_dirty() doesn\u0027t call __set_page_dirty_buffers() if CONFIG_BLOCK\n is not enabled.\n\n (*) fs/no-block.c is created to hold out-of-line stubs and things that are\n required when CONFIG_BLOCK is not set:\n\n (*) Default blockdev file operations (to give error ENODEV on opening).\n\n (*) Makes some /proc changes:\n\n (*) /proc/devices does not list any blockdevs.\n\n (*) /proc/diskstats and /proc/partitions are contingent on CONFIG_BLOCK.\n\n (*) Makes some compat ioctl handling contingent on CONFIG_BLOCK.\n\n (*) If CONFIG_BLOCK is not defined, makes sys_quotactl() return -ENODEV if\n given command other than Q_SYNC or if a special device is specified.\n\n (*) In init/do_mounts.c, no reference is made to the blockdev routines if\n CONFIG_BLOCK is not defined. This does not prohibit NFS roots or JFFS2.\n\n (*) The bdflush, ioprio_set and ioprio_get syscalls can now be absent (return\n error ENOSYS by way of cond_syscall if so).\n\n (*) The seclvl_bd_claim() and seclvl_bd_release() security calls do nothing if\n CONFIG_BLOCK is not set, since they can\u0027t then happen.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\nSigned-off-by: Jens Axboe \u003caxboe@kernel.dk\u003e\n" }, { "commit": "36695673b012096228ebdc1b39a6a5850daa474e", "tree": "4b617e27256750f367b2b50653981c70db0ce2d0", "parents": [ "863d5b822c02d0e7215fb84ca79e9f8c3e35f04e" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Tue Aug 29 19:06:16 2006 +0100" }, "committer": { "name": "Jens Axboe", "email": "axboe@nelson.home.kernel.dk", "time": "Sat Sep 30 20:52:28 2006 +0200" }, "message": "[PATCH] BLOCK: Move common FS-specific ioctls to linux/fs.h [try #6]\n\nMove common FS-specific ioctls from linux/ext2_fs.h to linux/fs.h as FS_IOC_*\nand FS_IOC32_* and have the users of them use those as a base.\n\nAlso move the GETFLAGS/SETFLAGS flags to linux/fs.h as FS_*_FL macros, and then\nhave the other users use them as a base.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\nSigned-off-by: Jens Axboe \u003caxboe@kernel.dk\u003e\n" }, { "commit": "cf9a2ae8d49948f861b56e5333530e491a9da190", "tree": "21f0b0d781b3e60cc60464d39b6d95681201b37e", "parents": [ "4090959aee403817ff386415f9bc602c1a0882ef" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Tue Aug 29 19:05:54 2006 +0100" }, "committer": { "name": "Jens Axboe", "email": "axboe@nelson.home.kernel.dk", "time": "Sat Sep 30 20:31:19 2006 +0200" }, "message": "[PATCH] BLOCK: Move functions out of buffer code [try #6]\n\nMove some functions out of the buffering code that aren\u0027t strictly buffering\nspecific.

For most filesystems, this should be done with simple_set_mnt()\nwhich will set the superblock pointer and then set the root dentry to the\nsuperblock\u0027s s_root (as per the old default behaviour).\n\nThe get_sb() op now returns an integer as there\u0027s now no need to return the\nsuperblock pointer.\n\nThis patch permits a superblock to be implicitly shared amongst several mount\npoints, such as can be done with NFS to avoid potential inode aliasing. In\nsuch a case, simple_set_mnt() would not be called, and instead the mnt_root\nand mnt_sb would be set directly.\n\nThe patch also makes the following changes:\n\n (*) the get_sb_*() convenience functions in the core kernel now take a vfsmount\n pointer argument and return an integer, so most filesystems have to change\n very little.\n\n (*) If one of the convenience function is not used, then get_sb() should\n normally call simple_set_mnt() to instantiate the vfsmount. This will\n always return 0, and so can be tail-called from get_sb().\n\n (*) generic_shutdown_super() now calls shrink_dcache_sb() to clean up the\n dcache upon superblock destruction rather than shrink_dcache_anon().\n\n This is required because the superblock may now have multiple trees that\n aren\u0027t actually bound to s_root, but that still need to be cleaned up. The\n currently called functions assume that the whole tree is rooted at s_root,\n and that anonymous dentries are not the roots of trees which results in\n dentries being left unculled.\n\n However, with the way NFS superblock sharing are currently set to be\n implemented, these assumptions are violated: the root of the filesystem is\n simply a dummy dentry and inode (the real inode for \u0027/\u0027 may well be\n inaccessible), and all the vfsmounts are rooted on anonymous[*] dentries\n with child trees.\n\n [*] Anonymous until discovered from another tree.\n\n (*) The documentation has been adjusted, including the additional bit of\n changing ext2_* into foo_* in the documentation.\n\n[akpm@osdl.org: convert ipath_fs, do other stuff]\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nAcked-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Nathan Scott \u003cnathans@sgi.com\u003e\nCc: Roland Dreier \u003crolandd@cisco.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "c89681ed7d0e4a61d35bdc12c06c6733b718b2cb", "tree": "170d7c54d578480ba231dd690243aa21067ca253", "parents": [ "09d967c6f32b35eab15b45862ae16e4f06259d8e" ], "author": { "name": "Miklos Szeredi", "email": "miklos@szeredi.hu", "time": "Thu Jun 22 14:47:22 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Thu Jun 22 15:05:57 2006 -0700" }, "message": "[PATCH] remove steal_locks()\n\nThis patch removes the steal_locks() function.\n\nsteal_locks() doesn\u0027t work correctly with any filesystem that does it\u0027s own\nlock management, including NFS, CIFS, etc.\n\nIn addition it has weird semantics on local filesystems in case tasks\nsharing file-descriptor tables are doing POSIX locking operations in\nparallel to execve().\n\nThe steal_locks() function has an effect on applications doing:\n\nclone(CLONE_FILES)\n /* in child */\n lock\n execve\n lock\n\nPOSIX locks acquired before execve (by \"child\", \"parent\" or any further\ntask sharing files_struct) will after the execve be owned exclusively by\n\"child\".\n\nAccording to Chris Wright some LSB/LTP kind of suite triggers without the\nstealing behavior, but there\u0027s no known real-world application that would\nalso fail.\n\nApps using NPTL are not affected, since all other threads are killed before\nexecve.\n\nApps using LinuxThreads are only affected if they\n\n -

Things which would require two or three syscalls with\n fadvise() can be done in a single syscall.\n\n- Using fadvise() in this manner is something not covered by POSIX.\n\nThe patch wires up the syscall for x86.\n\nThe sycall is implemented in the new fs/sync.c. The intention is that we can\nmove sys_fsync(), sys_fdatasync() and perhaps sys_sync() into there later.\n\nDocumentation for the syscall is in fs/sync.c.\n\nA test app (sync_file_range.c) is in\nhttp://www.zip.com.au/~akpm/linux/patches/stuff/ext3-tools.tar.gz.\n\nThe available-to-GPL-modules do_sync_file_range() is for knfsd: \"A COMMIT can\nsay NFS_DATA_SYNC or NFS_FILE_SYNC. I can skip the -\u003efsync call for\nNFS_DATA_SYNC which is hopefully the more common.\"\n\nNote: the `async\u0027 writeout mode SYNC_FILE_RANGE_WRITE will turn synchronous if\nthe queue is congested. This is trivial to fix: add a new flag bit, set\nwbc-\u003enonblocking. But I\u0027m not sure that we want to expose implementation\ndetails down to that level.\n\nNote: it\u0027s notable that we can sync an fd which wasn\u0027t opened for writing.\nSame with fsync() and fdatasync()).\n\nNote: the code takes some care to handle attempts to sync file contents\noutside the 16TB offset on 32-bit machines. It makes such attempts appear to\nsucceed, for best 32-bit/64-bit compatibility.

Any pages which are currently under\nwriteout are skipped, whether or not they are dirty.\n\nLINUX_FADV_WRITE_WAIT: wait upon writeout of any dirty pages between file\noffsets `offset\u0027 and `offset+len\u0027.\n\nBy combining these two operations the application may do several things:\n\nLINUX_FADV_ASYNC_WRITE: push some or all of the dirty pages at the disk.\n\nLINUX_FADV_WRITE_WAIT, LINUX_FADV_ASYNC_WRITE: push all of the currently dirty\npages at the disk.\n\nLINUX_FADV_WRITE_WAIT, LINUX_FADV_ASYNC_WRITE, LINUX_FADV_WRITE_WAIT: push all\nof the currently dirty pages at the disk, wait until they have been written.\n\nIt should be noted that none of these operations write out the file\u0027s\nmetadata. So unless the application is strictly performing overwrites of\nalready-instantiated disk blocks, there are no guarantees here that the data\nwill be available after a crash.\n\nTo complete this suite of operations I guess we should have a \"sync file\nmetadata only\" operation. This gives applications access to all the building\nblocks needed for all sorts of sync operations. But sync-metadata doesn\u0027t fit\nwell with the fadvise() interface. Probably it should be a new syscall:\nsys_fmetadatasync().\n\nThe patch also diddles with the meaning of `endbyte\u0027 in sys_fadvise64_64().\nIt is made to represent that last affected byte in the file (ie: it is\ninclusive). Generally, all these byterange and pagerange functions are\ninclusive so we can easily represent EOF with -1.\n\nAs Ulrich notes, these two functions are somewhat abusive of the fadvise()\nconcept, which appears to be \"set the future policy for this fd\".\n\nBut these commands are a perfect fit with the fadvise() impementation, and\nseveral of the existing fadvise() commands are synchronous and don\u0027t affect\nfuture policy either.
