101ee137 - udf: Drop VARCONV support

Wed, 18 Jan 2023 12:27:07 +0000

udf: Drop VARCONV supportUDF was supporting a strange mode where the media was containing 7blocks of unknown data for every 32 blocks of the filesystem. I have yetto see the media that would need such conversion (maybe it comes frompacket writing times) and the conversions have been inconsistent in thecode. In particular any write will write to a wrong block and corruptthe media. This is an indication and no user actually needs this solet's just drop the support instead of trying to fix it.Signed-off-by: Jan Kara List of files: /linux-6.15/fs/udf/misc.c

fcbf7637 - udf: Fix signed/unsigned format specifiers

Thu, 12 Oct 2017 13:48:41 +0000

udf: Fix signed/unsigned format specifiersFix problems noted in compilion with -Wformat=2 -Wformat-signedness.In particular, a mismatch between the signedness of a value and thesignedness of its format specifier can result in unsigned values beingprinted 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.

b490bdd6 - udf: Fix 64-bit sign extension issues affecting blocks > 0x7FFFFFFF

Thu, 12 Oct 2017 13:48:40 +0000

udf: Fix 64-bit sign extension issues affecting blocks > 0x7FFFFFFFLarge (> 1 TiB) UDF filesystems appear subject to several problems whenmounted 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 representationof UDF block addresses. Ultimately, all driver functions that manipulateUDF block addresses should use this type; for now, deployment is limitedto functions with actual or potential sign extension issues.Changes to udf_readdir() and udf_block_map() address the issues notedabove; other changes address potential similar issues uncovered duringaudit of the driver code.Signed-off-by: Steven J.

udf: move headers out include/linux/There's really no reason to keep udf headers in include/linux as they'renot 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 andinclude/linux/udf_fs.h into fs/udf/udfdecl.h.The only thing remaining in include/linux/ is a stub of udf_fs_i.hdefining the four user-visible udf ioctls. It's also moved fromunifdef-y to headers-y because it can be included unconditionally now.Signed-off-by: Christoph Hellwig Signed-off-by: Jan Kara List of files: /linux-6.15/fs/udf/misc.c
