Commit "initramfs: switch to tmpfs to fix ujail" switched initramfs to
now use tmpfs, it causes $(rootfs_type) to now return tmpfs when
running initramfs image instead of being empty.
This broke initramfs detection which prevents config files from
being saved as it does not work from initramfs.
So, lets test for $(rootfs_type) returning "tmpfs" instead.

Without the model-based devicename for LEDs, there are still cases
where a third component is required, typically when it refers to
internal "devices" like phys etc. An example are the following two
found on ramips:
- rt2800soc-phy0::radio
- rt2800pci-phy0::radio
So far, the rt2800*-phy: prefixes would be removed by the devicename
removal ("migration") script, and the configuration for these LEDs
would be broken.
To address this, this patch allows to add arguments to a call of
remove_devicename_leds, which will be compared against the first
part of the LED names/labels, and then be ignored by the routine,
and thus not removed:
remove_devicename_leds "rt2800soc-phy0" "rt2800pci-phy0"
This mechanism is supposed to be used when a "devicename" applies
to several devices. If only a single device is affected, it might
be more effective to use a case statement and exclude the device
from migration by that entirely.

Currently, we request LED labels in OpenWrt to follow the scheme
modelname:color:function
However, specifying the modelname at the beginning is actually
entirely useless for the devices we support in OpenWrt. In patches
subsequent to this one, we will thus remove the modelname from
the label definitions on various targets.
To migrate the existing definitions from older installations,
a migration script needs to be deployed that does
modelname:color:function -> color:function
e.g.
dir-789:green:status -> green:status
This patch introduces two functions that do exactly that:
For each entry in /etc/config/system, the routine will check whether
two (or more) colons are present, and then remove everything up to
(and including) the first colon.
For now, this will be applied unconditionally, i.e. if the function
is called for a device, all labels will be cut like this.
However, for a future case of mixed three-part and two-part labels,
it should not be too hard to provide a function argument with
exceptions to the removal.

vconfig has been disabled by default since 2015 [1] and there are
no remaining uses in entire OpenWrt trunk. However, we still set up
a specific name_type for it during boot.
While this setup is properly implemented to be only triggered when
vconfig is present, it still seems anachronistic and unnecessary
to set up a standard for a tool that is not used anymore.
Therefore, this removes the set_name_type initialization and leaves
it for those people actually using the tool to configure it as needed.

Set the default state for LEDs to off. When a trigger is set, the
trigger will turn the LED automatically on.
Currently LEDs might stay on, e.g. when the LED trigger is set to a
netdev trigger and the interface is never activated or the 'none'
trigger is selected without setting the 'default' option to 0 and it's
set for the LED indicating the system running state.
Using off as a default value is also consistent with the documentation

When passing a section or option value to config_get() which contains
characters that happen to be valid variable interpolation expressions,
the function returns a nonsensical expression result instead of the
expected empty string.
When the passed section or option name contains other characters which
are not valid within a shell variable name, a substitution error is
occuring instead.
The issue can be easily reproduced by one of the following examples:
root@OpenWrt:~# . /lib/functions.sh
root@OpenWrt:~# config load system
root@OpenWrt:~# config_get variable invalid-section option
root@OpenWrt:~# echo "$variable"
section_option:-

option:-
root@OpenWrt:~# . /lib/functions.sh
root@OpenWrt:~# config load system
root@OpenWrt:~# config_get variable section invalid@option

So far, the compatibility mechanism only works if both device and
image are already updated to the new routines. This patch extends
the sysupgrade metadata and fwtool_check_image() to account for
"older" images as well:
The basic mechanism for older devices to check for image compatibility
is the supported_devices entry. This can be exploited by putting
a custom message into this variable of the metadata, so older FW
will produce a mismatch and print the message as it thinks it's the
list of supported devices. So, we have two cases:
device 1.0, image 1.0:
The metadata will just contain supported_devices as before.
device 1.0, image 1.1:
The metadata will contain:
"new_supported_devices":["device_string1", "device_string2", ...],
"supported_devices":["Image version 1.1 incompatible to device: ..."]
If the device is "legacy", i.e. does not have the updated fwtool.sh,
it will just fail with image check and print the content of
supported_devices. If DEVICE_COMPAT_MESSAGE is set, this will be
printed on old devices as well through the same mechanism. Otherwise
a generic "Please check documentation ..." is appended.
Upgrade can still be performed with -F like when
SUPPORTED_DEVICES has been removed to prevent bricking.
If the device has updated fwtool.sh (but is 1.0), it will just use
the new_supported_devices instead, and work as intended (flashing
with -n will work, flashing without will print the appropriate
warning).
This mechanism should provide a fair tradeoff between simplicity
and functionality.
Since we touched a lot of fields in metadata, this also bumps
metadata_version to 1.1.

We regularly encounter the situation that devices are subject to
changes that will make them incompatible to previous versions.
Removing SUPPORTED_DEVICES will not really be helpful in most of these
cases, as this only helps after a rename.
To solve this situation, this patchset introduces a compatibility
version for devices. In this patch, the actual checks are implemented
into fwtool_check_image():
If an incompatible change is introduced, one can increase either
the minor version (1.0->1.1) or the major version (1.0->2.0).
Minor version increment:
This will still allow sysupgrade, but require to reset config
(-n or SAVE_CONFIG=0). If sysupgrade is called without -n, a
corresponding message will be printed. If sysupgrade is called
with -n, it will just pass, with supported devices being checked
as usual. (Which will allow us to add back SUPPORTED_DEVICES for
many cases.)
Major version increment:
This is meant for potential (rare) cases where sysupgrade is
not possible at all, because it would break the device.
In this case, a warning will be printed, and -n won't help.
If image check fails because of one of the versions parts not
matching, the content of DEVICE_COMPAT_MESSAGE is printed in
addition to the generic message (if set).
For both cases, upgrade can still be forced with -F as usual.

We regularly encounter the situation that devices are subject to
changes that will make them incompatible to previous versions.
Removing SUPPORTED_DEVICES will not really be helpful in most of these
cases, as this only helps after a rename.
To solve this situation, this patchset introduces a compatibility
version for devices. To complement the DEVICE_COMPAT_VERSION set
for the image to be flashed, this implements a compat_version on
the device, so it will have something to compare with the image.
The only viable way to achieve this seems to be via board.d files,
i.e. this is technically adding a compat version for the device's
config.
Like for the network setup, this will set up a command
ucidef_set_compat_version to set the compat_version in board.d.
This will then add a string to /etc/board.json, which will be
translated into uci system config by bin/config_generate.
By this, the compat_version, being a version of the config, will
also be exposed to the user.
As with DEVICE_COMPAT_VERSION, missing uci entry will be assumed
as compat_version "1.0", so we only need to add this if a device
needs to be bumped, e.g.
ucidef_set_compat_version "1.1"

Due to filesystem write caching the old configuration data could stay
out of flash for a long time during a first boot after the sysupgrade.
Power loss during this period could damage the overlay data and even
make device inaccessable via the network.
Fix this by syncing data to a flash as soon as the previous
configuration will be unpacked after the sysupgrade. Also sync the FS
state after the sysupgrade.tgz archive removing to prevent duplicative
extraction of a previous configuration.

tl;dr: dd will silently truncate the output if reading from special
files (e.g. sysfs attributes) with a too large bs parameter.
This problem was exposed on some RouterBOARD ipq40xx devices which use a
caldata payload which is larger than PAGE_SIZE, contrary to all other
currently supported RouterBOARD devices: the caldata would fail to
properly load with the current scripts.
Background: dd doesn't seem to correctly handle read() results that
return less than requested data. sysfs attributes have a kernel exchange
buffer which is at most PAGE_SIZE big, so only 1 page can be read() at a
time. In this case, if bs is larger than PAGE_SIZE, dd will silently
truncate blocks to PAGE_SIZE. With the current scripts using bs=<size>
count=1, the data is truncated to PAGE_SIZE as soon as the requested
<size> exceeds this value.
This commit works around this problem by using `cat` in the caldata
routines that can read from a file (routines that read from mtd devices
are untouched). cat correctly handles partial read requests. The output
is then piped to dd with the same parameters as before, to ensure that
the resulting file remains exactly the same.
This is a simple workaround, the downside is that it uses a pipe and one
more executable, and therefore has a larger memory footprint and is
slower. This is deemed acceptable considering these routines are only
used at boot time.
