bug.h: move BUILD_BUG_* defines to include/linux/bug.h

2016-01-25T15:39:59+00:00

BUILD_BUG_* macros have been defined in several headers.  It would
be nice to collect them in include/linux/bug.h like Linux.

This commit is cherry-picking useful macros from include/linux/bug.h
of Linux 4.4.

I did not import BUILD_BUG_ON_MSG() because it would not work if it
is used with include/common.h in U-Boot.  I'd like to postpone it
until the root cause (the "error()" macro in include/common.h causes
the name conflict with "__attribute__((error()))") is fixed.

Add more SPDX-License-Identifier tags

2016-01-19T13:31:21+00:00

In a number of places we had wordings of the GPL (or LGPL in a few
cases) license text that were split in such a way that it wasn't caught
previously.  Convert all of these to the correct SPDX-License-Identifier
tag.

ext4_common.c: Clean up failure cases in alloc_triple_indirect_block

2016-01-14T02:05:20+00:00

As noted by Coverity, when we have an error in
alloc_triple_indirect_block we will leak ti_pbuff_start_addr as it's not
being freed.  Further inspection here shows that we could also leak
ti_cbuff_start_addr in one corner case so free that as well.

block: pass block dev not num to read/write/erase()

2016-01-14T02:05:18+00:00

This will allow the implementation to make use of data in the block_dev
structure beyond the base device number. This will be useful so that eMMC
block devices can encompass the HW partition ID rather than treating this
out-of-band. Equally, the existence of the priv field is crying out for
this patch to exist.

fs: ext4: Prevent infinite loop in ext4fs_iterate_dir

2015-11-23T16:01:52+00:00

If the ext3 journal gets out of sync with what is written on disk, for
example because of an unexpected power cut, ext4fs_read_file can
return an all-zero directory entry.  In that case, ext4fs_iterate_dir
would infinite loop.

This patch detects when a directory entry's direntlen member is 0 and
returns a failure status, which breaks out of the infinite loop.  As a
result, U-Boot will not find files that may subsequently be recovered
when the journal is replayed.

This is better behaviour than hanging in an infinite loop, but as a
further improvement maybe U-Boot could interpret the ext3 journal and
actually find the unsynced entries.

Various Makefiles: Add SPDX-License-Identifier tags

2015-11-10T14:19:52+00:00

After consulting with some of the SPDX team, the conclusion is that
Makefiles are worth adding SPDX-License-Identifier tags too, and most of
ours have one.  This adds tags to ones that lack them and converts a few
that had full (or in one case, very partial) license blobs into the
equivalent tag.
