Some Arcadyan devices (e.g. MTS WG430223) keep their config in encrypted
mtd. This adds mtd_get_mac_encrypted_arcadyan() function to get the MAC
address from the encrypted partition. Function uses uencrypt utility for

618ab576be base-files: allow ignoring minor compat-version check
Downstream projects might re-generate device-specific configuration
based on OpenWrt's defaults on each upgrade, thus being unaffected by
forward- as well as backwards-breaking configuration.

Add a new sysupgrade parameter, which allows sysupgrades between minor
compat-versions. Upgrades will still fail upon mismatching major compat
versions.

base-files: make sure tools are present in sysupgrade ramdisk
Not all targets create /var/lock or touch /var/lock/fw_printenv.lock in
their platform.sh. This is problematic as fw_printenv then fails in
case /var/lock/fw_printenv.lock has not been created by previous calls
to fw_printenv/fw_setenv before sysupgrade is run.

Targets using fw_printenv/fw_setenv during sysupgrade:
 * ath79/*
 * ipq40xx/*
 * ipq806x/*
 * kirkwood/*
 * layerscape/*
 * mediatek/mt7622
 * mvebu/*
 * ramips/*
 * realtek/*

Targets currently using additional steps in /lib/upgrade/platform.sh
to make sure /var/lock/fw_printenv.lock (or at least /var/lock)
actually exists:
 * ath79/* (openmesh devices)
 * ipq40xx/* (linksys devices)
 * ipq806x/* (linksys devices)
 * kirkwood/* (linksys devices)
 * layerscape/*
 * mvebu/cortexa9 (linksys devices)

Given that accessing the U-Boot environment during sysupgrade is not
uncommon and the situation across targets is currently quite diverse,
just make sure both tools as well fw_env.config are always copied to
the ramdisk used for sysupgrade. Also make sure /var/lock always
exists.

This now allows to remove copying of fw_printenv/fw_setenv as well as
fw_env.config, creation of /var/lock or even /var/lock/fw_printenv.lock
from lib/upgrade/platform.sh or files included there.

As the same applies also to 'fwtool' which is used by generic eMMC
sysupgrade, also always copy that to ramdisk.

base-files: Make sure rootfs_data_max is considered
For sysupgrade on NAND/UBI devices there is the U-Boot environment
variable rootfs_data_max which can be used to limit the size of the
rootfs_data volume created on sysupgrade.
This stopped working reliable with recent kernels, probably due to a
race condition when reading the number of free erase blocks from sysfs
just after removing a volume.
Change the script to just try creating rootfs_data with the desired
size and retry with maximum size in case that fails. Hence calculating
the available size in the script can be dropped which works around the
problem.

base-files: add eMMC sysupgrade support
Adds generic support for sysupgrading on eMMC-based devices.

Provide function emmc_do_upgrade and emmc_copy_config to be used in
/lib/upgrade/platform.sh instead of redundantly implementing the same
logic over and over again.
Similar to generic sysupgrade on NAND, use environment variables
CI_KERNPART, CI_ROOTPART and newly introduce CI_DATAPART to indicate
GPT partition names to be used. On devices with more than one MMC
block device, CI_ROOTDEV can be used to specify the MMC device for
partition name lookups.

Also allow to select block devices directly using EMMC_KERN_DEV,
EMMC_ROOT_DEV and EMMC_DATA_DEV, as using GPT partition names is not
always an option (e.g. when forced to use MBR).

To easily handle writing kernel and rootfs make use of sysupgrade.tar
format convention which is also already used for generic NAND support.

f2c4064ecb base-files: dont always create kernel UBI volume
Currently nand_upgrade_tar() will pass the kernel length
to nand_upgrade_prepare_ubi() in all cases except for when
the kernel is to be installed in a separate partition as a
binary with the MTD tool.

While this is fine for almost all cases newer MikroTik NAND
devices like hAP ac3 require the kernel to be installed as a
UBIFS packed UBI volume in its own partition.

So, since we have a custom recipe to use ubiformat to flash
the kernel in its partition it makes no sense for sysupgrade
to also install the kernel as a UBI volume in the "ubi"
partition as it only wastes space and will never be used.

So, simply check whether CI_KERNPART is set to "none" and
if so unset the "has_kernel" variable which will in turn
prevent the kernel length from being passed on and then
the kernel UBI volume wont be created for no usefull purpose.

The ath79 MikroTik NAND target has been setting CI_KERNPART
to "none" for a while now altough that was not preventing
the kernel to be installed as UBI volume as well.

base-files: rename 'sdcard' to 'legacy-sdcard'
While an image layout based on MBR and 'bootfs' partition may be easy
to understand for users who are very used to the IBM PC and always have
the option to access the SD card outside of the device (and hence don't
really depend on other recovery methods or dual-boot), in my opinion
it's a dead end for many desirable features on embedded systems,
especially when managed remotely (and hence without an easy option to
access the SD card using another device in case things go wrong, for
example).

Let me explain:

* using a MSDOS/VFAT filesystem to store kernel(s) is problematic, as a
  single corruption of the bootfs can render the system into a state
  that it no longer boots at all. This makes dual-boot useless, or at
  least very tedious to setup with then 2 independent boot partitions
  to avoid the single point of failure on a "hot" block (the FAT index
  of the boot partition, written every time a file is changed in
  bootfs). And well: most targets even store the bootloader environment
  in a file in that very same FAT filesystem, hence it cannot be used
  to script a reliable dual-boot method (as loading the environment
  itself will already fail if the filesystem is corrupted).

* loading the kernel uImage from bootfs and using rootfs inside an
  additional partition means the bootloader can only validate the
  kernel -- if rootfs is broken or corrupted, this can lead to a reboot
  loop, which is often a quite costly thing to happen in terms of
  hardware lifetime.

* imitating MBR-boot behavior with a FAT-formatted bootfs partition
  (like IBM PC in the 80s and 90s) is just one of many choices on
  embedded targets. There are much better options with modern U-Boot
  (which is what we use and build from source for all targets booting
  off SD cards), see examples in mediatek/mt7622 and mediatek/mt7623.

Hence rename the 'sdcard' feature to 'legacy-sdcard', and prefix
functions with 'legacy_sdcard_' instead of 'sdcard_'.

b118aba8cb base-files: upgrade: use procd to kill managed daemons
These processes are managed by procd and set to start again when killed
via the procd instance parameter "respawn" being set during init.

Example:
procd_set_param respawn 3600 1 0

When they are killed manually during sysupgrade,
they are started again in 5 seconds or less, depending on
how the "respawn" parameter is set.

Use procd through ubus to disable the instances that respawn them,
however, allow dnsmasq, netifd, and logd to restart for remote logging.

Properly closing all these processes increases free memory by about 3 MB,
which should help low memory devices upgrade without crashing.

For very low memory devices (set to 32 MB for now)
also kill dnsmasq, netifd, and logd for an additional 3 MB of free memory.

Also, bump sleep values to allow at least 10 seconds
for network interfaces and daemons

before caches are dropped.

Check if firmware environment variable 'rootfs_data_max' exists and is

volume to that size instead of using the maximum available size.

This is useful on devices with lots of flash where users may want to
have eg. a volume for persistent logs and statistics or for external
applications/containers. Persistence on rootfs overlay is limited by
the size of memory available during the sysugprade process as that
data needs to be copied to RAM while the volume is being recreated
during sysupgrade. Hence it is unsuitable for keeping larger amounts
of data accross upgrade which makes additional volume(s) for
application data desirable.

e6aac8d98f image: add support for building FIT image with filesystem
Allow for single (external-data) FIT image to hold kernel, dtb and
squashfs. In that way, the bootloader verifies the system integrity
including the rootfs, because what's the point of checking that the
hash of the kernel is correct if it won't boot in case of squashfs
being corrupted? Better allow bootloader to check everything needed
to make it at least up to failsafe mode. As a positive side effect
this change also makes the sysupgrade process on nand potentially
much easier as it is now.
In short: mkimage has a parameter '-E' which allows generating FIT
images with 'external' data rather than embedding the data into the
device-tree blob itself. In this way, the FIT structure itself remains
small and can be parsed easily (rather than having to page around
megabytes of image content). This patch makes use of that and adds
support for adding sub-images of type 'filesystem' which are used to
store the squashfs. Now U-Boot can verify the whole OS and the new
partition parsers added in the Linux kernel can detect the filesystem
sub-images, create partitions for them, and select the active rootfs
volume based on the configuration in FIT (passing configuration via
device tree could be implemented easily at a later stage).

This new FIT partition parser works for NOR flash (on top of mtdblock),

(ie. eMMC, SDcard, SATA, NVME, ...).
It could even be used to mount such FIT images via `losetup -P` on a
user PC if this patch gets included in Linux upstream one day ;)

396a35dd51 base-files: remove execute bit and shebang from functions.sh
/lib/functions.sh was executable for no obvious reason and its
execute property was even checked in package-ipkg.mk just to
source it afterwards.

Remove the execute bit and shebang as this is clearly a library.

331892f85f treewide: drop shebang from non-executable lib files
This drops the shebang from another bunch of files in various /lib
folders, as these are sourced and the shebang is useless.

Fix execute bit in one case, too.

This should cover almost all trivial cases now, i.e. where /lib is
actually used for library files.

While the speed improvement might be negligible, there is still no

927b9df938 x86/efi: add FAT32 esp mounting support
Adds a new function get_magic_fat32() in base-files to read FAT32 magic.
Now FAT32 EFI system partition can be handled in the same way as FAT12/FAT16.

49d678f0d2 base-files: allow reusing of boolean value extraction logic
The `functions.sh` script has `config_get_bool()` function, which is
usable when using UCI config direct access API, but there is no
equivalent for the callback API. Introduce `get_bool()` function to
allow reusing it from init scripts.

Example:

```sh
option_cb() {
    local option="$1"
    local value="$(get_bool "$2")"
    ...
}
```

3d12b47985 base-files: flush kernel memory cache during sysupgrade
Flush kernel memory caches during sysupgrade in order
to mitigate the impact from memory consumption spikes
in low-RAM devices.

This may help to prevent sysupgrade causing a reboot
before the actual flashing starts.

d82c191283 package/base-files: caldata: use dd iflag fullblock
This dd flag ensures that the requested size
is retrieved from pipes or special filesystems (if available).

Without this flag, on multi-core systems,
Piped or special filesystem data can be truncated
when a size greater than PIPE_BUF is requested.

9290539ca9 base-files: allow setting device and bridge macs
Add code for setting mac addresses inside board.json and rendering
them out to uci. On switches we want to have a unique MAC on each port.
With 48 port switches that would require 48 device sections in
/etc/config/network. Doing so via board.json is easier.
