0c18c5679a base-files: export whole disk of fitblk backing partition
After commit ad62247800 ("base-files: improve lib/upgrade/common.sh")
behavior of export_bootdevice has been made consistent in such way that
always the whole disk device is exported (as that was the case already
when matching via UUID) rather than the partition device.
Do the same for the device holding the fitblk backing partition.

5992f976b3 base-files: recognize bootdevice on devices using fitblk
Boards using the fitblk driver need special treatment when it comes to
detecting the actual block device used to store the image used to boot
from. Transparently handle this in 'export_bootdevice' and provide new
'fitblk_get_bootdev' function to replace implementations in
/lib/upgrade/platform.sh.

base-files: sysupgrade: Add 2 sec sleep into process KILL loop
Add 2 seconds sleep after each forcibly killed/tried-to-kill process
in the final process termination loop in sysupgrade stage2.

This is needed especially for qualcommax/ipq807x, where ath11k
wireless driver may have a long 10-20 seconds delay after termination
before actually getting killed. This often breaks sysupgrade.

The current KILL loop in kill_remaining does all 10 kill attempts
consecutively without any delay, as evidenced here in a failing sysupgrade.
It does not allow any time for the process to finalize its internal
termination.

The change in this commit adds a 2 seconds delay after each kill attempt

9710712120 base-files: accept gzipped nand sysupgrade images
When firmware images only contained compressed kernels and squashfs roots,
uncompressed tar files were a good option. We are now using UBIFS images,
both raw and tarred, as well as ubinized (full UBI partition) images, all
of which benefit greatly from compression.

For example, a raw ubinized backup taken from a running Askey RT4230W REV6
(such full backups can be restored via the LUCI's sysupgrade UI) is over
400 MB, but compresses to less than 10 MB.

This commit adds support for gzipped versions of all file types already
accepted by the nand sysupgrade mechanism, be them raw or tarred.

7d02fc0951 base-files: fix sysupgrade for kernel-out-of-UBI
Commit ecbcc0b595 bricks devices on which the raw kernel and UBI mtd
partitions overlap.

This is the case of the ZyXEL NR7101 for example. Its OEM bootloader has
no UBI support. OpenWrt splits the stock kernel mtd partition into a raw
kernel part used by the bootloader and a UBI part used to store rootfs
and rootfs_data. Running mtd erase on the complete partition during
sysupgrade erases the UBI part and results in a soft brick.

Arguably the best solution would be to fix the partition layouts so that
kernel and UBI partitions do not overlap, also including a stock_kernel
partition to help reverting to stock firmware. This would have the added
benefit of protecting UBI from kernel images that are excessively large.

17b05045bd ipq40xx: Support Chromium OS image-type creation
See firmware-utils.git commits [1], which implemented the cros-vbutil
verified-boot payload-packing tool, and extended ptgen for the CrOS
kernel partition type. With these, it's now possible to package kernel +
rootfs to make disk images that can boot a Chrome OS-based system (e.g.,
Chromebooks, or even a few AP models).

Regarding PARTUUID= changes: Chromium bootloaders work well with a
partition number offset (i.e., relative to the kernel partition), so
we'll be using a slightly different root UUID line.

NB: I've made this support specific to ip40xx for now, because I only
plan to support an IPQ4019-based AP that uses a Chromium-based
bootloader, but this image format can be used for essentially any
Chromebook, as well as the Google OnHub, a prior Chromium-based AP using
an IPQ8064 chipset.

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.

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: stage2: improve /proc/*/stat parser
Simply reading /proc/*/stat as a space-separated string will not work
as the process name may itself contain spaces. Hence we must match on
the '(' and ')' characters around the process name and can then handle
the remaining string as space-separated values.
This fixes shell error messages which have been popping up the console
due to spaces in process names being interpreted as field separators.

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_'.

base-files: sysupgrade stage2: fix losetup detection
If the busybox applet losetup was selected, `command -v` selects that
during sysupgrade. As this applet is in another path and doesn't cover
the '-D' option which is used to make sure user-defined loop devices
are no longer active during sysupgrade.
Detect losetup at the path of the full utility to avoid error messages
in case of the busybox applet being selected.

d374e2cdb4 base-files: upgrade: use zcat command provided by busybox
Calling `switch_to_ramfs()` will not copy the gzip executable
(/bin/gzip) to ramfs, but `/bin/zcat` will call `/bin/gzip` when
package gzip is installed, instead of the busybox-supplied zcat.
This will cause `zcat` to fail to find `gzip`, then cause the
sysupgrade to fail. Adding the `busybox` prefix here will solve
the problem.
