ubi: wl: Fix uninitialized variable

2019-05-07T19:58:33+00:00

There is a potential execution path in which variable *err*
is compared against UBI_IO_BITFLIPS without being properly
initialized previously.

Fix this by initializing variable *err* to 0.

ubi: wl: Silence uninitialized variable warning

2019-03-05T20:21:07+00:00

This condition needs to be fipped around because "err" is uninitialized
when "force" is set.  The Smatch static analysis tool complains and
UBsan will also complain at runtime.

ubi: Expose the bitrot interface

2019-02-24T10:40:45+00:00

Using UBI_IOCRPEB and UBI_IOCSPEB userspace can force
reading and scrubbing of PEBs.

In case of bitflips UBI will automatically take action
and move data to a different PEB.
This interface allows a daemon to foster your NAND.

ubi: Introduce in_pq()

2019-02-24T10:13:44+00:00

This function works like in_wl_tree() but checks whether an ubi_wl_entry
is currently in the protection queue.
We need this function to query the current state of an ubi_wl_entry.

ubi: Do not drop UBI device reference before using

2018-12-13T21:09:44+00:00

The UBI device reference is dropped but then the device is used as a
parameter of ubi_err. The bug is introduced in changing ubi_err's
behavior. The old ubi_err does not require a UBI device as its first
parameter, but the new one does.

ubi: Put MTD device after it is not used

2018-12-13T21:09:32+00:00

The MTD device reference is dropped via put_mtd_device, however its
field ->index is read and passed to ubi_msg. To fix this, the patch
moves the reference dropping after calling ubi_msg.

where we are expecting to fall through.
