UBIFS: correct data corruption range

2013-10-26T10:33:38+00:00

With power-cut emulation, it is possible that sometimes no data at all is
corrupted and that confusing messages are printed due to errors in the
computation of data corruption range.

[1] The start of the range should be [0..len-1], not [0..len].
[2] The end of the range should always be at least 1 greater than the start.

UBIFS: rename random32() to prandom_u32()

2013-01-15T13:45:27+00:00

Use more preferable function name which implies using a pseudo-random
number generator.

ubifs: use prandom_bytes

This also converts filling memory loop to use memset.

UBIFS: fix power cut emulation for mtdram

2012-08-31T14:32:38+00:00

The power cut emulation did not work correctly because we corrupted more than
one max. I/O unit in the buffer and then wrote the entire buffer. This lead to
recovery errors because UBIFS complained about corrupted free space. And this
was easily reproducible on mtdram because max. write size is very small there
(64 bytes), and we could easily have a 1KiB buffer, corrupt 128 bytes there,
and then write the entire buffer.

The fix is to corrupt max. write size bytes at most, and write only up to the
last corrupted max. write size chunk, not the entire buffer.

UBIFS: always print full error reports

2012-08-22T14:41:44+00:00

Even when we are emulating power cuts, otherwise it is difficult to investigate
failures during emulated power cuts testing.
