This avoids a possible denial of service attack. Thanks to Carl-Daniel Hailfinger from SuSE for pointing this out. - Fix compilation warnings on ia64. (Randy Dunlap) - - Use i_size_read() in fs/ntfs/attrib.c::ntfs_attr_set(). - - Use i_size_read() in fs/ntfs/logfile.c::ntfs_{check,empty}_logfile(). - - Use i_size_read() once and then use the cached value in - fs/ntfs/lcnalloc.c::ntfs_cluster_alloc(). - - Use i_size_read() in fs/ntfs/file.c::ntfs_file_open(). + - Use i_size_{read,write}() instead of reading i_size by hand and cache + the value where apropriate. - Add size_lock to the ntfs_inode structure. This is an rw spinlock and it locks against access to the inode sizes. Note, ->size_lock is also accessed from irq context so you must use the _irqsave and - _irqrestore lock and unlock functions, respectively. - - Use i_size_read() in fs/ntfs/compress.c at the start of the read and - use the cached value afterwards. Cache the initialized_size in the - same way and protect access to the two sizes using the size_lock. - - Use i_size_read() in fs/ntfs/dir.c once and then use the cached - value afterwards. - - Use i_size_read() in fs/ntfs/super.c once and then use the cached - value afterwards. Cache the initialized_size in the same way and - protect access to the two sizes using the size_lock. + _irqrestore lock and unlock functions, respectively. Protect all + accesses to allocated_size, initialized_size, and compressed_size. - Minor optimization to fs/ntfs/super.c::ntfs_statfs() and its helpers. - - Use i_size_read() in fs/ntfs/inode.c once and then use the cached - value afterwards when reading the size of the bitmap inode. - - Use i_size_{read,write}() in fs/ntfs/{aops.c,mft.c} and protect - access to the i_size and other size fields using the size_lock. - Implement extension of resident files in the regular file write code paths (fs/ntfs/aops.c::ntfs_{prepare,commit}_write()). At present this only works until the data attribute becomes too big for the mft |
