UBI: fix debugging messages

2012-01-26T01:24:44+00:00

commit 72f0d453d81d35087b1d3ad7c8285628c2be6e1d upstream.

Patch ab50ff684707031ed4bad2fdd313208ae392e5bb broke UBI debugging messages:
before that commit when UBI debugging was enabled, users saw few useful
debugging messages after attaching an MTD device. However, that patch turned
'dbg_msg()' into 'pr_debug()', so to enable the debugging messages users have
to enable them first via /sys/kernel/debug/dynamic_debug/control, which is
very impractical.

This commit makes 'dbg_msg()' to use 'printk()' instead of 'pr_debug()', just
as it was before the breakage.

UBI: fix nameless volumes handling

2012-01-26T01:24:44+00:00

commit 4a59c797a18917a5cf3ff7ade296b46134d91e6a upstream.

Currently it's possible to create a volume without a name. E.g:
ubimkvol -n 32 -s 2MiB -t static /dev/ubi0 -N ""

After that vtbl_check() will always fail because it does not permit
empty strings.

UBI: fix use-after-free on error path

2012-01-26T01:24:37+00:00

commit e57e0d8e818512047fe379157c3f77f1b9fabffb upstream.

When we fail to erase a PEB, we free the corresponding erase entry object,
but then re-schedule this object if the error code was something like -EAGAIN.
Obviously, it is a bug to use the object after we have freed it.

UBI: fix missing scrub when there is a bit-flip

2012-01-26T01:24:37+00:00

commit e801e128b2200c40a0ec236cf2330b2586b6e05a upstream.

Under some cases, when scrubbing the PEB if we did not get the lock on
the PEB it fails to scrub. Add that PEB again to the scrub list

Artem: minor amendments.

The older add_mtd_device()/add_mtd_partitions() and their removal

and mtd_device_unregister().

UBI: turn some macros into static inline

2011-05-20T05:30:34+00:00

Similarly as we have done for UBIFS in
1dcffad74183bb00e8129ba1c5bb2c9931d31bd7, turn the debugging macros into static
inline functions, for the same reasons: to avoid gcc 4.5 warnings.

UBI: improve checking in debugging prints

2011-05-20T05:30:34+00:00

When debugging is disabled, define debugging prints as if (0) printk() to make
sure that the compiler still the format string in debugging messages even if
debugging is disabled.

UBI: fix typo in a message

2011-04-14T10:38:59+00:00

When a PEB passes the torture test, UBI prints
"do not mark it a bad", but should print "do not mark it as bad".
This patch corrects the typo.
