The AFS v2 parser uses footer[8] to locate the image information block
inside the current erase block, then uses the image information
region_count to walk entries from a fixed local array. The footer offset
and region count come from flash contents and are not checked against the
erase block or the local image-info array before use.
Reject v2 entries whose image information offset would underflow the
erase block calculation, and reject region counts that cannot fit in the
local image-info array before walking region entries.

RedBoot FIS partition names are stored in a fixed 16-byte field that is
expected to be NUL-terminated. parse_redboot_partitions() used strlen()
to size the names area and later copied the same field with strcpy(), so
a malformed table entry without a terminator could make both operations
read beyond the descriptor.
Validate each accepted FIS name with strnlen() before adding it to the
partition list.

mtdconcat finally makes it in, after several years of being merged and
reverted.
Baikal SoC support is being removed, so MTD bits are being removed as
well.
All the other changes are misc cleanups.
* NAND changes
The main changes happened in the SunXi driver in order to
support new versions of the Allwinner NAND controller.
There are also some DT-binding improvements and cleanups.
Finally a couple of actual fixes (Realtek ECC and Winbond SPI NAND),
aside with the usual load of misc changes.
* SPI NOR changes
There is only a collection of bugfixes this time around, with no notable
changes to the core. Some of the more noteworthy bugfixes listed below.
- Enable die erase on MT35XU02GCBA. We knew this flash needed this fixup
since 7f77c561e2 ("mtd: spi-nor: micron-st: add TODO for fixing
mt35xu02gcba") but did not add it due to lack of hardware to test on.
- Fix locking on some Winbond w25q series flashes.
- Fix Auto Address Increment (AAI) writes on SST that flashes that start
on odd address. The write enable latch needs to be set again after the
single byte program.

In order to parse sub-partitions, add_mtd_partitions() calls
parse_mtd_partitions() for all previously found partitions.
Each partition will end up being passed to parse_fixed_partitions(), and
its of_node will be treated as the ofpart_node.
Commit 7cce81df7d ("mtd: parsers: ofpart: fix OF node refcount leak in
parse_fixed_partitions()") added of_node_put() calls for ofpart_node on
all exit paths.
In the case where the partition passed to parse_fixed_partitions() has a
parent, it is treated as a dedicated partitions node, and of_node_put()
is wrongly called for it, even if of_node_get() was not called
explicitly.
On repeated bind / unbinds of the MTD, the extra of_node_put() ends up
decrementing the refcount down to 0, which should never happen,
resulting in the following error:
OF: ERROR: of_node_release() detected bad of_node_put() on
/soc/spi@80007000/flash@0/partitions/partition@0
Call of_node_get() to balance the call to of_node_put() done for

finishes. for_each_child_of_node() correctly calls of_node_put() for all
device nodes it iterates over as long as we don't break or jump out of

Calling of_node_put() inside the ofpart_none path will wrongly decrement
the ref count of the last node in the for_each_child_of_node() loop.
Move the call to of_node_put() under the ofpart_fail label to fix this.

This fortify warning looks legit to me -- this code used to be reading

Since the size of the dynamic allocation is calculated with strlen()
we can use strcmp() instead of memcmp() and remain within bounds.

This converts some of the visually simpler cases that have been split
over multiple lines. I only did the ones that are easy to verify the
resulting diff by having just that final GFP_KERNEL argument on the next
line.
Somebody should probably do a proper coccinelle script for this, but for
me the trivial script actually resulted in an assertion failure in the
middle of the script. I probably had made it a bit _too_ trivial.
So after fighting that far a while I decided to just do some of the
syntactically simpler cases with variations of the previous 'sed'
scripts.
The more syntactically complex multi-line cases would mostly really want
whitespace cleanup anyway.

This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

of_get_child_by_name() returns a node pointer with refcount incremented,
which must be released with of_node_put() when done. However, in
parse_fixed_partitions(), when dedicated is true (i.e., a "partitions"
subnode was found), the ofpart_node obtained from of_get_child_by_name()
is never released on any code path.
Add of_node_put(ofpart_node) calls on all exit paths when dedicated is
true to fix the reference count leak.

mtd_parser_tplink_safeloader_read_table(). If the allocation for

Fix this by freeing the temporary buffer buf in the err_free label.

Currently even if none of the custom parsers are selected a struct
of_device_id and a dummy function that just returns -EOPNOTSUPP is
compiled in for each of them.
Its not obvious from the code but struct of_device_id is massive,
196 or 200 bytes (see link), so this is a lot more wasteful than you'd
think just skimming the code and assuming the wasted size is just the
length of the string with some small overhead.
If they aren't enabled use ifdef's to avoid anything being compiled
in and remove the dummy functions.

Since commit 8b41fc4454 ("kbuild: create modules.builtin without
Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations
are used to identify modules. As a consequence, uses of the macro
in non-modules will cause modprobe to misidentify their containing
object file as a module when it is not (false positives), and modprobe
might succeed rather than failing with a suitable error message.
So remove it in the files in this commit, none of which can be built as

SPI NOR changes:
* small fixes on core and spansion driver.
Add a mechanism to handle the case in which partitions are present as
direct child of the nand controller node and #size-cells is set to <0>.
This could happen if the nand-controller node in the DTS is supposed to
have #size-cells set to 0, but for some historical reason/bug it was set
to 1 in the past, and the firmware (e.g. U-Boot) is adding the partition
as direct children of the nand-controller defaulting to #size-cells
being to 1.
This prevents a real boot failure on colibri-imx7 that happened during v6.1
development cycles.

Commit dd5c672d7c ("arm64: bcmbca: Merge ARCH_BCM4908 to ARCH_BCMBCA")
removes config ARCH_BCM4908 as config ARCH_BCMBCA has the same intent.
Probably due to concurrent development, commit 002181f5b1 ("mtd: parsers:

create a reference to a non-existing config symbol.
Adjust the MTD_BRCM_U_BOOT definition to refer to ARCH_BCMBCA instead of
ARCH_BCM4908 to remove the reference to the non-existing config symbol
ARCH_BCM4908.

There is already a real partitions.yaml file, so assuming everybody
knows hot to read yaml schema now, this text file is no longer needed,
so drop it.
Depending on the situation, the lines referring to this file are either
dropped or edited to point to mtd.yaml which includes partition{,s}.yaml.

On 64 bit systems, the highest 32 bits of the "offset" variable are
not initialized. Also the existing code is not endian safe (it will
fail on big endian systems). Change the type of "offset" to a u32.

There is some code in the parser that tries to read 0x8000
bytes into a block to "read in the middle" of the block. Well
that only works if the block is also 0x10000 bytes all the time,
else we get these parse errors as we reach the end of the flash:
spi-nor spi0.0: mx25l1606e (2048 Kbytes)
mtd_read error while parsing (offset: 0x200000): -22
mtd_read error while parsing (offset: 0x201000): -22
(...)
Fix the code to do what I think was intended.

This adds an MTD partition parser for the Sercomm partition table that
is used in some Beeline, Netgear and Sercomm routers.
The Sercomm partition map table contains real partition offsets, which
may differ from device to device depending on the number and location of
bad blocks on NAND.

In the event of a skipped partition (case when the entry name is empty)
the kernel panics in the cleanup function as the name entry is NULL.
Rework the parser logic by first checking the real partition number and
then allocate the space and set the data for the valid partitions.
The logic was also fundamentally wrong as with a skipped partition, the
parts number returned was incorrect by not decreasing it for the skipped
partitions.
