cf7154db07 kernel: only optimized for size if small_flash
Add a new config option to allow to select the default compile
optimization level for the kernel.

Select the optimization for size by default if the small_flash feature is
set. Otherwise "Optimize for performance" is set.

Add the small_flash feature flag to all (sub)targets which had the
optimization for size in their default kernel config.

Remove CC_OPTIMIZE_FOR_* symbols from all kernel configs to apply the new
setting.

Exceptions to the above are:

  - lantiq, where the optimization for size is only required for the
    xway_legacy subtarget but was set for the whole target
  - mediatek, ramips/mt7620 & ramips/mt76x8 where boards should have
    plenty of space and an optimization for size doesn't make much sense
  - rb532, which has 128MByte flash

8b42a260ed mac80211: Expose support for ath9k Dynack
Enables support for Dynack feature.

When a remote station is far away, we need to compensate for the distance
by allowing more time for an ACK to arrive back before issueing a retransmission.
Currently, it needs to be set fixed to indicate the maximum distance the remote
station will ever be.

While this mostly works for static antennae, it introduces 2 issues:
- If the actual distance is less, speed is reduced due to a lot of wates wait-time
- If the distance becomes greater, retries start to occur and comms can get lost.

Allowing to set it dynamically using dynack ensures the best possible tradeoff
between speed vs distance.

This feature is currently only supported in ath9k.
it is also disabled by default.

Enabling it can be done in 2 ways:
- issue cmd:  iw phy0 set distance auto
- sending the NL80211_ATTR_WIPHY_DYN_ACK flag to mac80211 driver using netlink

Disabling it can be done by providing a valid fixed value.

To give an idea of a practical example:

In my usecase, we have mesh wifi device installed on ships/platforms.
Currently, the coverage class is set at 12000m fixed.

When a vessel moved closer (ex. 1500m), the measured link capacity was a lot
lower compared to setting the coverage class fixed to 1500m

Dynack completely solved this, nearly providing double the bandwidth at closer range
compared to the fixed setting of 12000m being used.

Also when a vessel sailed to a distance greater than the fixed setting,
communication was lost as the ACK's never arrived within the max allowed timeframe.

Actual distance: 6010m
iperf 60s run avg

Fixed 12150m:  31 Mbit/s
Dynack:        58 Mbit/s

Fixed 6300m:   51 Mbit/s
Dynack:        59 Mbit/s

Fixed 3000m:   13 Mbit/s  (lots of retries)
Dynack:        58 Mbit/s

Actual distance: 1504m
iperf 60s run avg

Fixed 12150m:  31 Mbit/s
Dynack:        86 Mbit/s

Fixed 6300m:   55 Mbit/s
Dynack:        87 Mbit/s

Fixed 3000m:   67 Mbit/s
Dynack:        87 Mbit/s

Debug messages now make sense again.

* wg-quick: android: support excluding applications

Android now supports excluding certain apps (uids) from the tunnel.

* selftest: ratelimiter: improve chance of success via retry
* qemu: bump default kernel version
* qemu: decide debug kernel based on KERNEL_VERSION

Some improvements to our testing infrastructure.

* receive: use NAPI on the receive path

This is a big change that should both improve preemption latency (by not
disabling it unconditionally) and vastly improve rx performance on most
systems by using NAPI. The main purpose of this snapshot is to test out this
technique.

a5188eb258 nasm: disable LTO, remove host specific workarounds
The recent build failures on various platforms were apparently caused by
the fact that LTO build support in the configure script does not check
if it has a suitable version of gcc and simply assumes that gcc-ar is
available and can be used for intermediate files.

Since we really don't need to build nasm with LTO, simply disable it and
keep the whole build more portable

6476148034 ath79: add support for OCEDO Raccoon
This commit adds support for the OCEDO Raccoon

SOC:	Atheros AR9344
RAM:    128MB
FLASH:  16MiB
WLAN1:  AR9344 2.4 GHz 802.11bgn 2x2
WLAN2:  AR9382 5 GHz 802.11an 2x2
INPUT:  RESET button
LED:    Power, LAN, WiFi 2.4, WiFi 5
Serial: Header Next to Black metal shield
        Pinout is 3.3V - GND - TX - RX (Arrow Pad is 3.3V)
        The Serial setting is 115200-8-N-1.

	NOTE: The U-Boot won't boot with the serial attached.
	Boot the device without serial attached and attach it
	after 3 seconds.

Tested and working:
 - Ethernet
 - 2.4 GHz WiFi
 - 5 GHz WiFi
 - TFTP boot from ramdisk image
 - Installation via ramdisk image
 - OpenWRT sysupgrade
 - Buttons
 - LEDs

Installation seems to be possible only through booting an OpenWRT
ramdisk image.

Hold down the reset button while powering on the device. It will load a
ramdisk image named 'raccoon-uImage-initramfs-lzma.bin' from 192.168.100.8.

Note: depending on the present software, the device might also try to
pull a file called 'raccoon-uimage-factory'. Only the name differs, it
is still used as a ramdisk image.

Wait for the ramdisk image to boot. OpenWRT can be written to the flash
via sysupgrade or mtd.

Due to the flip-flop bootloader which we not (yet) support, you need to
set the partition the bootloader is selecting. It is possible from the
initramfs image with

 > fw_setenv bootcmd run bootcmd_1

Afterwards you can reboot the device.

0b83a23560 ramips: add support for I-O DATA WN-AX1167GR
I-O DATA WN-AX1167GR is a 2.4/5 GHz band 11ac router, based on
MediaTek MT7621A.

Specification:

- MT7621A (2-Cores, 4-Threads)
- 64 MB of RAM (DDR2)
- 16 MB of Flash (SPI)
- 2T2R 2.4/5 GHz
- 5x 10/100/1000 Mbps Ethernet
- 2x LEDs, 4x keys (2x buttons, 1x slide switch)
- UART header on PCB
  - Vcc, GND, TX, RX from ethernet port side
  - baudrate: 115200 bps (U-Boot, OpenWrt)

Stock firmware:

In the stock firmware, WN-AX1167GR has two os images each composed of
Linux kernel and rootfs.
These images are stored in "Kernel" and "app" partition of the
following partitions, respectively.

(excerpt from dmesg):

MX25L12805D(c2 2018c220) (16384 Kbytes)
mtd .name = raspi, .size = 0x01000000 (16M) .erasesize = 0x00010000 (64K) .numeraseregions = 0
Creating 10 MTD partitions on "raspi":
0x000000000000-0x000001000000 : "ALL"
0x000000000000-0x000000030000 : "Bootloader"
0x000000030000-0x000000040000 : "Config "
0x000000040000-0x000000050000 : "Factory"
0x000000050000-0x000000060000 : "iNIC_rf"
0x000000060000-0x0000007e0000 : "Kernel"
0x000000800000-0x000000f80000 : "app"
0x000000f90000-0x000000fa0000 : "Key"

0x000000fb0000-0x000001000000 : "storage"

The flag for boot partition is stored in "Key" partition, and U-Boot
reads this and determines the partition to boot.

If the image that U-Boot first reads according to the flag is
"Bad Magic Number", U-Boot then tries to boot from the other image.
If the second image is correct, change the flag to the number
corresponding to that image and boot from that image.

(example):

## Booting image at bc800000 ...
Bad Magic Number,FFFFFFFF
Boot from KERNEL 1  !!
## Booting image at bc060000 ...
   Image Name:   MIPS OpenWrt Linux-4.14.50

87493dac11 mac80211: initialize sinfo in cfg80211_get_station
Most of the implementations behind cfg80211_get_station will not initialize
sinfo to zero before manipulating it. For example, the member "filled",
which indicates the filled in parts of this struct, is often only modified
by enabling certain bits in the bitfield while keeping the remaining bits
in their original state. A caller without a preinitialized sinfo.filled can
then no longer decide which parts of sinfo were filled in by
cfg80211_get_station (or actually the underlying implementations).

cfg80211_get_station must therefore take care that sinfo is initialized to
zero. Otherwise, the caller may tries to read information which was not
filled in and which must therefore also be considered uninitialized. In
batadv_v_elp_get_throughput's case, an invalid "random" expected throughput
may be stored for this neighbor and thus the B.A.T.M.A.N V algorithm may
switch to non-optimal neighbors for certain destinations.

1c01e02575 ath10k-ct: search DT for BDF variant info
Board Data File (BDF) is loaded upon driver boot-up procedure. The right
board data file is identified on QCA4019 using bus, bmi-chip-id and
bmi-board-id.

The problem, however, can occur when the (default) board data file cannot
fulfill the vendor requirements and it is necessary to use a different
board data file.

This problem was solved for SMBIOS by adding a special SMBIOS type 0xF8.
Something similar has to be provided for systems without SMBIOS but with
device trees. No solution was specified by QCA and therefore a new one has
to be found for ath10k.

The device tree requires addition strings to define the variant name

    wifi@a000000 {
    	status = "okay";
    	qcom,ath10k-calibration-variant = "RT-AC58U";
    };

    wifi@a800000 {
    	status = "okay";
    	qcom,ath10k-calibration-variant = "RT-AC58U";
    };

This would create the boarddata identifiers for the board-2.bin search

 *  bus=ahb,bmi-chip-id=0,bmi-board-id=16,variant=RT-AC58U
 *  bus=ahb,bmi-chip-id=0,bmi-board-id=17,variant=RT-AC58U

206fbbfec2 config: add config option for KERNEL_TASKSTATS
In order for monitoring tools such as atop and htop to track and report
i/o data, kernel support for task statistics and io accounting is
required.

Add a config option to enable building this support in the kernel.

b19622044d mbedtls: Activate deterministic ECDSA
With deterministic ECDSA the value k needed for the ECDSA signature is
not randomly generated any more, but generated from a hash over the
private key and the message to sign. If the value k used in a ECDSA
signature or the relationship between the two values k used in two
different ECDSA signatures over the same content is know to an attacker
he can derive the private key pretty easily. Using deterministic ECDSA
as defined in the RFC6979 removes this problem by deriving the value k
deterministically from the private key and the content which gets
signed.

The resulting signature is still compatible to signatures generated not
deterministic.

This increases the size of the ipk on mips 24Kc by about 2 KByte.
old:
166.240 libmbedtls_2.11.0-1_mips_24kc.ipk
new:
167.811 libmbedtls_2.11.0-1_mips_24kc.ipk

This does not change the ECDSA performance in a measurable way.

5a078180d0 mbedtls: Disable MBEDTLS_SHA256_SMALLER implementation
Disable MBEDTLS_SHA256_SMALLER implementation, not enabled by default in
upstream and reduces performance by quite a bit.

Source: include/mbedtls/config.h

Enable an implementation of SHA-256 that has lower ROM footprint but also
lower performance.

The default implementation is meant to be a reasonnable compromise between
performance and size. This version optimizes more aggressively for size at
the expense of performance. Eg on Cortex-M4 it reduces the size of
mbedtls_sha256_process() from ~2KB to ~0.5KB for a performance hit of
about 30%.

The size of mbedtls increased a little bit:
ipkg for mips_24kc before:
164.382 Bytes
ipkg for mips_24kc after:
166.240 Bytes
