udf: Check length of extended attributes and allocation descriptors

2015-09-18T01:20:45Z

commit 23b133bdc452aa441fcb9b82cbf6dd05cfd342d0 upstream. Check length of extended attributes and allocation descriptors when loading inodes from disk. Otherwise corrupted filesystems could confuse the code and make the kernel oops. Reported-by: Carl Henrik Lunde Signed-off-by: Jan Kara [lizf: Backported to 3.4: - call make_bad_inode() and then return - relace bs with inode->i_sb->s_blocksize] Signed-off-by: Zefan Li

udf: Verify i_size when loading inode

2015-04-14T09:33:47Z

commit e159332b9af4b04d882dbcfe1bb0117f0a6d4b58 upstream. Verify that inode size is sane when loading inode with data stored in ICB. Otherwise we may get confused later when working with the inode and inode size is too big. Reported-by: Carl Henrik Lunde Signed-off-by: Jan Kara [lizf: Backported to 3.4: just return on error, as there's no "out" label] Signed-off-by: Zefan Li

udf: don't increment lenExtents while writing to a hole

2013-01-17T16:50:53Z

commit fb719c59bdb4fca86ee1fd1f42ab3735ca12b6b2 upstream. Incrementing lenExtents even while writing to a hole is bad for performance as calls to udf_discard_prealloc and udf_truncate_tail_extent would not return from start if isize != lenExtents Signed-off-by: Namjae Jeon Signed-off-by: Ashish Sangwan Signed-off-by: Jan Kara Signed-off-by: Shuah Khan Signed-off-by: Greg Kroah-Hartman

udf: fix memory leak while allocating blocks during write

2013-01-17T16:50:53Z

commit 2fb7d99d0de3fd8ae869f35ab682581d8455887a upstream. Need to brelse the buffer_head stored in cur_epos and next_epos. Signed-off-by: Namjae Jeon Signed-off-by: Ashish Sangwan Signed-off-by: Jan Kara Signed-off-by: Shuah Khan Signed-off-by: Greg Kroah-Hartman

udf: Fix file entry logicalBlocksRecorded

2012-02-29T20:53:47Z

ECMA 1.67 requires setting logicalBlocksRecorded to zero if the file has no extents. This should be checked in udf_update_inode(). udf_fill_inode() will then take care of itself. Signed-off-by: Steven P. Nickel Signed-off-by: Jan Kara

udf: Init/maintain file entry checkpoint field

2012-02-29T20:53:46Z

In accordance with ECMA 1.67 Part 4, 14.9.15, the checkpoint field should be initialized to 1 at creation. (Zero is *not* a valid value.) Signed-off-by: Steven P. Nickel Signed-off-by: Jan Kara

udf: Fix deadlock when converting file from in-ICB one to normal one

2012-01-09T12:52:08Z

During BKL removal in 2.6.38, conversion of files from in-ICB format to normal format got broken. We call ->writepage with i_data_sem held but udf_get_block() also acquires i_data_sem thus creating A-A deadlock. We fix the problem by dropping i_data_sem before calling ->writepage() which is safe since i_mutex still protects us against any changes in the file. Also fix pagelock - i_data_sem lock inversion in udf_expand_file_adinicb() by dropping i_data_sem before calling find_or_create_page().

udf: Cleanup calling convention of inode_getblk()

2012-01-09T12:52:08Z

inode_getblk() always returned NULL and passed results in its parameters. Make the function return something useful - found block number. Signed-off-by: Jan Kara

udf: propagate umode_t

2012-01-04T03:55:08Z

note re mount options: fmask and dmask are explicitly truncated to 12bit, UDF_INVALID_MODE just needs to be guaranteed to differ from any such value. And umask is used only in &= with umode_t, so we ignore other bits anyway. Signed-off-by: Al Viro
