* fs: udf: Replace GPL 2.0 boilerplate license notice with SPDX identifierBagas Sanjaya2023-05-301-5/+1

* udf: Drop VARCONV supportJan Kara2023-01-261-17/+1
| | | | | | | | | | | | UDF was supporting a strange mode where the media was containing 7 blocks of unknown data for every 32 blocks of the filesystem. I have yet to see the media that would need such conversion (maybe it comes from packet writing times) and the conversions have been inconsistent in the code. In particular any write will write to a wrong block and corrupt the media. This is an indication and no user actually needs this so let's just drop the support instead of trying to fix it.

* udf_get_extendedattr() had no boundary checks.Stian Skjelstad2021-08-231-2/+11
| | | | | | | | | When parsing the ExtendedAttr data, malicous or corrupt attribute length could cause kernel hangs and buffer overruns in some special cases.

* udf: Fix signed/unsigned format specifiersSteve Magnani2017-10-171-2/+2
| | | | | | | | | | | | | | | | | | Fix problems noted in compilion with -Wformat=2 -Wformat-signedness. In particular, a mismatch between the signedness of a value and the signedness of its format specifier can result in unsigned values being printed as negative numbers, e.g.: Partition (0 type 1511) starts at physical 460, block length -1779968542 ...which occurs when mounting a large (> 1 TiB) UDF partition. Changes since V1: * Fixed additional issues noted in udf_bitmap_free_blocks(), udf_get_fileident(), udf_show_options() Signed-off-by: Steven J.

* udf: Fix 64-bit sign extension issues affecting blocks > 0x7FFFFFFFSteve Magnani2017-10-171-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | Large (> 1 TiB) UDF filesystems appear subject to several problems when mounted on 64-bit systems: * readdir() can fail on a directory containing File Identifiers residing above 0x7FFFFFFF. This manifests as a 'ls' command failing with EIO. * FIBMAP on a file block located above 0x7FFFFFFF can return a negative value. The low 32 bits are correct, but applications that don't mask the high 32 bits of the result can perform incorrectly. Per suggestion by Jan Kara, introduce a udf_pblk_t type for representation of UDF block addresses. Ultimately, all driver functions that manipulate UDF block addresses should use this type; for now, deployment is limited to functions with actual or potential sign extension issues. Changes to udf_readdir() and udf_block_map() address the issues noted above; other changes address potential similar issues uncovered during audit of the driver code. Signed-off-by: Steven J.

* udf: Rename udf_error to udf_errJoe Perches2011-10-101-10/+8
| | | | | | | | | | | | | | | | | | Rename udf_error to udf_err for consistency with normal logging uses of pr_err. Rename function udf_err to _udf_err. Remove __func__ from uses and move __func__ to a new udf_err macro that calls _udf_err. Some of the udf_error uses had \n terminations, some did not so standardize \n's to udf_err uses, remove \n from _udf_err function. Coalesce udf_err formats. One message prefixed with udf_read_super is now prefixed with udf_fill_super.

* udf: Promote some debugging messages to udf_errorJoe Perches2011-10-101-4/+9
| | | | | | | | | | | | | | If there is a problem with a scratched disc or loader, it's valuable to know which error occurred. Convert some debug messages to udf_error, neaten those messages too. Add the calculated tag checksum and the read checksum to error message. Make udf_error a public function and move the logging prototypes together.

* udf: Fix handling of multisession mediaSebastian Manciulea2008-04-171-8/+5
| | | | | | | | | | According to OSTA UDF specification, only anchor blocks and primary volume descriptors are placed on media relative to the last session. All other block numbers are absolute (in the partition or the whole media). This seems to be confirmed by multisession media created by other systems.

* udf: move headers out include/linux/Christoph Hellwig2008-04-171-1/+0
| | | | | | | | | | | | | | | | There's really no reason to keep udf headers in include/linux as they're not used by anything but fs/udf/. This patch merges most of include/linux/udf_fs_i.h into fs/udf/udf_i.h, include/linux/udf_fs_sb.h into fs/udf/udf_sb.h and include/linux/udf_fs.h into fs/udf/udfdecl.h. The only thing remaining in include/linux/ is a stub of udf_fs_i.h defining the four user-visible udf ioctls. It's also moved from unifdef-y to headers-y because it can be included unconditionally now. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jan Kara <jack@suse.cz>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
