ext2fs: fix warning: 'blocknxt' may be used uninitialized

2012-07-08T20:55:04+00:00

This warning was introduced in 436da3c "ext2load: increase read
speed":

ext2fs.c: In function 'ext2fs_read_file':
ext2fs.c:458:19: warning: 'blocknxt' may be used uninitialized in this function [-Wuninitialized]

this change makes it go away.

ext2load: increase read speed

2012-06-21T20:49:33+00:00

This patch dramatically drops the amount of time u-boot needs to read a
file from an ext2 partition.  On a typical 2 to 5 MB file (kernels and
initrds) it goes from tens of seconds to a couple seconds.

All we are doing here is grouping contiguous blocks into one read.

Boot tested on Globalscale Technologies Dreamplug (Kirkwood ARM SoC)
with three different files.  sha1sums were calculated in Linux
userspace, and then confirmed after ext2load.

gunzip: rename z{alloc, free} to gz{alloc, free}

2012-04-30T14:54:51+00:00

This allows us to add a proper zalloc() func (one that does a zeroing
alloc), and removes duplicate prototypes.

FAT write: Fix compile errors

2012-03-24T22:27:32+00:00

This patch removes compile errors introduced by
commit 9813b750f32c0056f0a35813b9a9ec0f68b664af
'fs/fat: Fix FAT detection to support non-DOS partition tables'

fat_write.c: In function 'disk_write':
fat_write.c:54: error: 'part_offset' undeclared (first use in this function)
fat_write.c:54: error: (Each undeclared identifier is reported only once
fat_write.c:54: error: for each function it appears in.)
fat_write.c: In function 'do_fat_write':
fat_write.c:950: error: 'part_size' undeclared (first use in this function)

These errors only appear when this code is enabled by
defining CONFIG_FAT_WRITE option.

FAT: update the second FAT when writing a file

2012-01-05T19:10:38+00:00

After susccessful write to the FAT partition,
fsck program may print warning message due to different FAT,
provided that the filesystem supports two FATs.

This patch makes the second FAT to be same with the first one
when writing a file.

fs/fat: Improve error handling

2012-01-05T19:10:37+00:00

The FAT filesystem fails silently in inexplicable ways when given a
filesystem with a block-size that does not match the device sector size.
In theory this is not an unsupportable combination but requires a major
rewrite of a lot of the filesystem.  Until that occurs, the filesystem
should detect that scenario and display a helpful error message.

This scenario in particular occurred on a 512-byte blocksize FAT fs
stored in an El-Torito boot volume on a CD-ROM (2048-byte sector size).

Additionally, in many circumstances the ->block_read method will not
return a negative number to indicate an error but instead return 0 to
indicate the number of blocks successfully read (IE: None).

The FAT filesystem should defensively check to ensure that it got all of
the sectors that it asked for when reading.
