* iget: stop HOSTFS from using iget() and read_inode()David Howells2008-02-07
| | | | | | | | | | | | | | | | | | | | | | | | Stop the HOSTFS filesystem from using iget() and read_inode(). Provide hostfs_iget(), and call that instead of iget(). hostfs_iget() then uses iget_locked() directly and returns a proper error code instead of an inode in the event of an error. hostfs_fill_sb_common() returns any error incurred when getting the root inode instead of EINVAL. Note that the contents of hostfs_kern.c need to be examined: (*) hostfs_iget() should perhaps subsume init_inode() and hostfs_read_inode(). (*) It would appear that all hostfs inodes are the same inode because iget() was being called with inode number 0 - which forms the lookup key.

Rename the old do_ioctl to vfs_ioctl because the names vfs_XXX should preferably be reserved to callable VFS functions which modules may call, as many other vfs_XXX functions already do.

| * brk randomization: introduce CONFIG_COMPAT_BRKIngo Molnar2008-02-06
| | | | | | | | | | | | | | | | | | | | | | | | based on similar patch from: Pavel Machek <pavel@ucw.cz> Introduce CONFIG_COMPAT_BRK. If disabled then the kernel is free (but not obliged to) randomize the brk area. Heap randomization breaks ancient binaries, so we keep COMPAT_BRK enabled by default.

* | ext3: fix lock inversion in direct IOJan Kara2008-02-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We cannot start transaction in ext3_direct_IO() and just let it last during the whole write because dio_get_page() acquires mmap_sem which ranks above transaction start (e.g. because we have dependency chain mmap_sem->PageLock->journal_start, or because we update atime while holding mmap_sem) and thus deadlocks could happen. We solve the problem by starting a transaction separately for each ext3_get_block() call. We *could* have a problem that we allocate a block and before its data are written out the machine crashes and thus we expose stale data. But that does not happen because for hole-filling generic code falls back to buffered writes and for file extension, we add inode to orphan list and thus in case of crash, journal replay will truncate inode back to the original size.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ext3 file system was by default ignoring errors and continuing. This is not a good default as continuing on error could lead to file system corruption. Change the default to mark the file system readonly. Debian and ubuntu already does this as the default in their fstab.
