udf: Propagate errors from udf_truncate_extents()

2019-03-18T15:30:02+00:00

Make udf_truncate_extents() properly propagate errors to its callers and
let udf_setsize() handle the error properly as well. This lets userspace
know in case there's some error when truncating blocks.

udf: Fix crash on IO error during truncate

2019-03-18T15:29:52+00:00

When truncate(2) hits IO error when reading indirect extent block the
code just bugs with:

kernel BUG at linux-4.15.0/fs/udf/truncate.c:249!
...

Fix the problem by bailing out cleanly in case of IO error.

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

2017-10-17T09:56:45+00:00

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.

udf: Do not decrement i_blocks when freeing indirect extent block

2012-07-09T11:24:21+00:00

Indirect extent block is not accounted in i_blocks during allocation
thus we should not decrement i_blocks when we are freeing such block
during truncation.

udf: Convert printks to pr_

2011-10-31T22:43:52+00:00

Use the current logging styles.

Convert a few printks that should have been udf_warn and udf_err.
Coalesce formats.  Add #define pr_fmt.
Move an #include "udfdecls.h" above other includes in udftime.c
so pr_fmt works correctly.  Strip prefixes from conversions as appropriate.
Reorder logging definitions in udfdecl.h
