[PATCH 0/3] UBI: block: Some fixes for static volumes

Hi all,

This patchset addresses some issues found when using static volumes
and playing with volume resize, update, and truncate operations.

The first patch changes the block interface to use the volume 'used_bytes'
which is the actual data size. It fixes a current issue with static volumes
which produces a nasty error when they are read past the data offset.

$ cat /dev/ubiblock0_0 > /dev/null
UBI error: ubiblock_read_to_buf: ubiblock0_0 ubi_read error -22
end_request: I/O error, dev ubiblock0_0, sector 9536
Buffer I/O error on device ubiblock0_0, logical block 2384
[snip]

It's an annoying error, but on the other side, it should never be produced
if the block is used to mount a file system, so I'm not sure it's serious
enough to go the -stable.

The second and third patches add the required changes for the block interface
to catch the "volume updated" notification. For static volumes, the
'used_bytes' parameter can be changed when updating the volume.

Comments and feedback welcome!

  UBI: block: Add support for the UBI_VOLUME_UPDATED notification
  UBI: Dispatch update notification if the volume is updated

ubifs_dump_node must bounds check ubifs_ch->len

I believe that ubifs_dump_node() must bounds check ch->len in the
UBIFS_DATA_NODE case. It currently does not which resulted in a crash
on a system. See below.

This is the source code as it stands today:

int dlen = le32_to_cpu(ch->len) - UBIFS_DATA_NODE_SZ;
print_hex_dump(KERN_ERR, "\t", DUMP_PREFIX_OFFSET, 32, 1,
                               (void *)&dn->data, dlen, 0);

For some reason, ch->len was 47. UBIFS_DATA_NODE_SZ appears to be 48,
so dlen got assigned -1 which is then coerced into a size_t. Since
size_t is unsigned, it effectively passes 0xFFFFFFFF to
print_hex_dump().

Hm, at the very least there ought to be a cond_resched() in there
somewhere. But really, the problem is that the iteration over inodes to
be checked is *entirely* naïve.

[PATCH 1/2] mtd: nand: Base BCH ECC bytes on required strength

From: Jordan Friendshuh <jfriendshuh <at> xes-inc.com>

NAND devices with page sizes over 4 KiB require more than 4-bits of ECC
coverage. This patch calculates the value of ecc_bytes based on a still
assumed 512-byte step size (13-bits) and the ecc_strength.

Example:
Micron M73A devices (8 KiB page) require 8-bit ECC per 512-byte

[PATCH] mkfs.ubifs: use gid from table instead 2x uid

If the devtable is used then the tool uses uid twice and doesn't

cfi_intelext_is_locked() misses get_chip()/put_chip() calls

Hi,

cfi_intelext_is_locked() in cfi_cmdset_0001.c calls 
do_getlockstatus_oneblock() withou calling get_chip() before and 
put_chip() afterwards. So chip state is changed without protection.
This may lead to hanging processes.

Is this analysis correct?

If someone can fix this quickly - fine - but I can also provide a patch.

greets,
ron

[PATCH] mtd: bcm53xxspiflash: new driver for SPI flahes on Broadcom ARM SoCs

Broadcom ARM SoCs often include SPI controller, it's used to attach
flash chip. It's registered as "bcm53xxspiflash" SPI device.
This patch adds SPI driver that handles such flashes. It uses spi-nor
framework to share some code and devices database.

Support for wait_till_ready is not implemented yet, so it's disabled
(depends on BROKEN) right now. We'll be able to enable it once we clean
the wait_till_ready.

Signed-off-by: Rafał Miłecki <zajec5 <at> gmail.com>
---
This driver was succesfully tested with two ARM routers, one with
"w25q128" and the other one with "mx25l25635f" chips. Support for the
"mx25l25635f" is currently not included, as it needs some cleaning
before I can push it.

This driver doesn't work for flash found in Netgear R6250. It replies
with 0xFF all the time, so it may be some bug in controller driver.
