* udf: Make stat on symlink report symlink length as st_sizeJan Kara2017-01-051-0/+1
| | | | | | | | | | UDF encodes symlinks in a more complex fashion and thus i_size of a symlink does not match the lenght of a string returned by readlink(2). This confuses some applications (see bug 191241) and may be considered a violation of POSIX. Fix the problem by reading the link into page cache in response to stat(2) call and report the length of the decoded path. Signed-off-by: Jan Kara <jack@suse.cz>

* udf: Fix conversion of 'dstring' fields to UTF8Andrew Gabbasov2016-04-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 9293fcfbc1812a22ad5ce1b542eb90c1bbe01be1 ("udf: Remove struct ustr as non-needed intermediate storage"), while getting rid of 'struct ustr', does not take any special care of 'dstring' fields and effectively use fixed field length instead of actual string length, encoded in the last byte of the field. Also, commit 484a10f49387e4386bf2708532e75bf78ffea2cb ("udf: Merge linux specific translation into CS0 conversion function") introduced checking of the length of the string being converted, requiring proper alignment to number of bytes constituing each character. The UDF volume identifier is represented as a 32-bytes 'dstring', and needs to be converted from CS0 to UTF8, while mounting UDF filesystem. The changes in mentioned commits can in some cases lead to incorrect handling of volume identifier: - if the actual string in 'dstring' is of maximal length and does not have zero bytes separating it from dstring encoded length in last byte, that last byte may be included in conversion, thus making incorrect resulting string; - if the identifier is encoded with 2-bytes characters (compression code is 16), the length of 31 bytes (32 bytes of field length minus 1 byte of compression code), taken as the string length, is reported as an incorrect (unaligned) length, and the conversion fails, which in its turn leads to volume mounting failure. This patch introduces handling of 'dstring' encoded length field in udf_CS0toUTF8 function, that is used in all and only cases when 'dstring' fields are converted. Currently these cases are processing of Volume Identifier and Volume Set Identifier fields. The function is also renamed to udf_dstrCS0toUTF8 to distinctly indicate that it handles 'dstring' input.

* udf: Remove struct ustr as non-needed intermediate storageAndrew Gabbasov2016-02-091-10/+3
| | | | | | | | | | | | | | | | | | | | Although 'struct ustr' tries to structurize the data by combining the string and its length, it doesn't actually make much benefit, since it saves only one parameter, but introduces an extra copying of the whole buffer, serving as an intermediate storage. It looks quite inefficient and not actually needed. This commit gets rid of the struct ustr by changing the parameters of some functions appropriately. Also, it removes using 'dstring' type, since it doesn't make much sense too. Just using the occasion, add a 'const' qualifier to udf_get_filename to make consistent parameters sets.

* udf: Adjust UDF_NAME_LEN to better reflect actual restrictionsAndrew Gabbasov2016-02-091-3/+3
| | | | | | | | | | | | | | | | | Actual name length restriction is 254 bytes, this is used in 'ustr' structure, and this is what fits into UDF File Ident structures. And in most cases the constant is used as UDF_NAME_LEN-2. So, it's better to just modify the constant to make it closer to reality. Also, in some cases it's useful to have a separate constant for the maximum length of file name field in CS0 encoding in UDF File Ident structures. Also, remove the unused UDF_PATH_LEN constant.

Although all call sites still have this length the same, this parameterization will make the function more universal and also consistent with udf_get_filename.

| | | | | | | | | | | | Symlink reading code does not check whether the resulting path fits into the page provided by the generic code. This isn't as easy as just checking the symlink size because of various encoding conversions we perform on path. So we have to check whether there is still enough space in the buffer on the fly.

* udf: Fix loading of special inodesJan Kara2014-10-091-1/+12
| | | | | | | | | | | | | | | Some UDF media have special inodes (like VAT or metadata partition inodes) whose link_count is 0. Thus commit 4071b9136223 (udf: Properly detect stale inodes) broke loading these inodes because udf_iget() started returning -ESTALE for them. Since we still need to properly detect stale inodes queried by NFS, create two variants of udf_iget() - one which is used for looking up special inodes (which ignores link_count == 0) and one which is used for other cases which return ESTALE when link_count == 0.

* udf: add extent cache support in case of file readingNamjae Jeon2013-01-221-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements extent caching in case of file reading. While reading a file, currently, UDF reads metadata serially which takes a lot of time depending on the number of extents present in the file. Caching last accessd extent improves metadata read time. Instead of reading file metadata from start, now we read from the cached extent. This patch considerably improves the time spent by CPU in kernel mode.

If the filesystem is on some phase change media, this leads to its quick degradation as such media is able to handle only 10000 overwrites or so. We solve the problem by writing new information into LVID only on umount, remount-ro and sync. This solves the problem at the price of longer media inconsistency (previously media became consistent after pdflush flushed dirty LVID buffer) but that should be acceptable.
