31e99fe3da which introduced this code was unfortunately untested.
This commit fixes a number of issues and works around the fact that in
this particular scheme, the LZO payload may be padded at the end which
will trigger a harmless lzo decompression error.
This commit also disambiguates the debug printks.

(cherry picked from commit 2ea481193c)
Some newer MikroTik RouterBOARD devices use a new encoding scheme
for their WLAN calibration data. This patch provides support for
decoding this new scheme.
Signed-off-by: Thibaut VARÈNE <hacks@slashdirt.org>
This driver exposes the data encoded in the "hard_config" flash segment
of MikroTik RouterBOARDs devices. It presents the data in a sysfs folder
named "hard_config". The WLAN calibration data is available on demand via
the 'wlan_data' sysfs file in that folder.
This driver permanently allocates a chunk of RAM as large as the
"hard_config" MTD partition (typically 4KB), although it is technically
possible to operate entirely from the MTD device without using a local
buffer (except when requesting WLAN calibration data), at the cost of a
performance penalty.
This driver does not reuse any of the existing code previously found in
routerboot.c.
This driver has been successfully tested on BE (ath79) and LE (ipq40xx
and ramips) hardware.

ar8229 and ar8236 don't allow unknown unicast/multicast frames and
broadcast frames to be flooded to cpu port. This isn't desired behavior
for swconfig as we treat it as a standalone switch.
Current code doesn't enable unicast frame flooding for ar8229 and uses
wrong setup for ar8236. This commit fixes both of them by enabling port
0 flooding for all unknown frames.

Upstream commit dda9f4b9ca ("f2fs: fix to skip verifying block address
for non-regular inode").
On 4.14, attempting to perform operations on a non-regular inode
residing on an f2fs filesystem, such rm-ing a device node, would fail
and lead to a warning / call trace in dmesg. This fix was already
applied to other kernels upstream - including 4.19, from which the patch
was taken.

The Atheros AR8327 and AR8337 have (according to their datasheet) a
VLAN table with a maximum of 4096 entries.
Currently, there's a hard limit of 128 VLANs, which is the same as
for most other Atheros switches. Increase this limit only for the
AR83x7 series and modify some shared functions to allow them to work
with a variable max VLAN count.

This fixes off-by-one error introduced in commit dc76900021
("kernel: Correctly search for the FIT image in mtd partition.")
Function `mtd_read` starts reading at `offset` and
needs `hdr_len` number of bytes to be available. Suppose
the easiest case when `offset` is `0` and `hdr_len` equals
to `mtd->size` - the `for` loop will not be entered even
when enough bytes are available to be read.
Same happens for any non-zero `offset`, when `hdr_len` is
just enough bytes to be read until `mtd->size` is reached.
Imagine that for example `mtd->size=5`, `offset=4` and
`hdr_len=1`. Then `offset+hdr_len=5` and the check has to
be `offset+hdr_len <= mtd->size`, i.e. `5 <= 5`. The
check for `offset + hdr_len` value needs to be inclusive,
therefore use `<=`.

Commit fcb41decf6 ("config: enable some useful features on
!SMALL_FLASH devices") enabled netns, which in turn lead to the crash in
the flow offload target.
When the flow offloading framework intends to delete a flow from the
hardware table, it is necessary to retrieve the namespace from
nf_flowtable->ft_net. However, no one ever wrote the namespace into
nf_flowtable->ft_net in advance. So the framework will mistakenly use a
NULL namespace to execute dev_get_by_index_rcu(net, ifindex), leading to
the kernel panic.
