Revert "fs: ext4: check the minimal partition size to mount"

2023-10-18T00:50:52+00:00

This check breaks small partitions (under 1024 blocks) because part_length
is in units of part.blksz and not bytes. Given the purpose of this
function, we really want to make sure the partition is SUPERBLOCK_START +
SUPERBLOCK_SIZE (2048) bytes so we can call ext4_read_superblock without
error.

The obvious solution is to convert callers from things like

	ext4fs_mount(part_info.size)

to

	ext4fs_mount(part_info.size * part_info.blksz);

However, I'm not really a fan of the bloat that would cause, especially
since the error is now suppressed. I think the best course of action here
is to just revert the patch.

This reverts commit 9905cae65e03335aefcb1ebfab5b7ee62d89f64e.

fs: ext4: fix files seen as symlink during deletion

2023-03-30T19:09:59+00:00

The deletion process handles special case for symlinks whose target are
small enough that it fits in struct ext2_inode.b.symlink. So no block had
been allocated. But the check of file type wrongly considered regular
files as symlink. So, no block was freed. So, the EXT4 partition could be
corrupted because of no free block available.

fs: ext4: check the minimal partition size to mount

2023-03-22T16:51:14+00:00

No need to mount a too small partition to handle a EXT4 file system.

This patch add a test on partition size before to read the
SUPERBLOCK_SIZE buffer and avoid error latter in fs_devread() function.

fs: ext4: Fix free(NULL)

2022-12-08T14:28:31+00:00

The 'depth_dirname', 'ptr', 'parent_inode' and 'first_inode' pointers
may be null. Thus, it is necessary to check them before using free() to
avoid free(NULL) cases.

fs: Quieten down the filesystems more

2022-10-18T03:17:12+00:00

When looking for a filesystem on a partition we should do so quietly. At
present if the filesystem is very small (e.g. 512 bytes) we get a host of
messages.

Update these to only show when debugging.

fs: ext4: Use CRC-16 implementation from linux/crc16.h

2022-04-21T18:32:40+00:00

Implementation in linux/crc16.h provides standard CRC-16 algorithm with
polynomial x^16 + x^15 + x^2 + 1. Use it and remove duplicate ext4 CRC-16
specific code.

part: Drop disk_partition_t typedef

2020-05-18T21:33:33+00:00

We should not be using typedefs and these make it harder to use
forward declarations (to reduce header file inclusions). Drop the typedef.
