c5bf9a8ced base-files: gpio switch: add named GPIO support
Previously, gpio_switch only accepts GPIO pin number as input. Once a
GPIO pin is exported and named by device tree, its pin state cannot be
configured and saved across reboots by UCI.

This patch adds support for named GPIO pins. Thus GPIO pin can be
exported by device tree with active high/low correctly configured,
having human-readable name in /sys/class/gpio/ is also now possible.

More importantly, GPIO pins which are referenced by name will be immune
from pin mapping breakage while unintentional pin number changes are
introduced by kernel or driver updates.

880c1f0336 base-files: prevent issues w/ overlay on powerloss after sysupgrade
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.

Tested with AMD Geode based board.

7557e7f267 package/base-files: caldata: work around dd's limitation
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.

282e817350 base-files: do not source system.sh in functions.sh
The default_postinst() function in /lib/functions.sh sources
/lib/functions/system.sh before cycling through uci-defaults files.

This creates a pseudo-cyclic dependency as system.sh also uses
functions that are located in functions.sh. Despite that, there
is actually only one uci-defaults file in the entire repo that needs
system.sh, and this one contains an explicit source for system.sh
anyway.

Consequently, this patch removes the sourcing of system.sh in
functions.sh. There are no relevant uses in packages, routing and
luci repositories.
This may require adjustments for downstream, though.

12020f8a95 base-files: Add /etc/shinit for non-login shell init
Because /etc/profile (and ~/.profile) are read by login shells only,
aliases and functions defined there are not available to non-login
shells, e.g. when using screen or tmux.

If the ENV environment variable exists (exported by /etc/profile or
~/.profile) and references an existing file, then all interactive shells
(login or non-login) will read that file as well.

This sets the ENV environment variable in /etc/profile, pointing to
/etc/shinit.

This also adds /etc/shinit, which:

* Contains alias and function definitions originally in /etc/profile

* Sources /etc/mkshrc if the user is using mksh (also originally in
  /etc/profile), as /etc/mkshrc is meant for all interactive shells

* Sources ~/.mkshrc if the user is using mksh, to compensate for the
  fact that mksh will not read ~/.mkshrc if ENV is set

* Sources ~/.shinit if the user is not using mksh

This also removes the shebang from /etc/profile, as the file is sourced,
not executed.

a422b171ac base-files: diag: restore default trigger for 'boot' LED
For devices without a dedicated 'diag' LED, we use sometimes one of
other LEDs for indicating at least 'boot', 'failsafe' and 'upgrade'
stages. In some cases, at the same time these LEDs have defined default
triggers in DTS using 'linux,default-trigger' property. Current 'diag'
setup removes the trigger and turns off 'boot' LED after bootup.

One of the examples of such device is TP-Link TL-WR841N v14 (ramips)
which uses 'wlan' LED with defined 'linux,default-trigger' for 'diag':

aliases {
        led-boot = &led_wlan;
        led-failsafe = &led_wlan;
        led-upgrade = &led_wlan;
};

[...]

led_wlan: wlan {
        label = "tl-wr841n-v14:green:wlan";
        gpios = <&gpio1 9 GPIO_ACTIVE_LOW>;
        linux,default-trigger = "phy0tpt";
};

This patch extends 'diag.sh' and 'leds.sh' scripts to make sure default
trigger defined in DTS is restored for 'diag' LED which isn't used for
indicating 'running' stage.

174ff7d754 base-files: send informational UDP message each second waiting
The preinit network initialisation and failsafe informational message
are inherently racy as the interface takes some time to become
functional after "ip link set $pi_ifname up" command.

Consider this timing:

[   12.002713] IPv6: ADDRCONF(NETDEV_UP): eth1: link is not ready
[   12.008819] IPv6: ADDRCONF(NETDEV_UP): eth1.1: link is not ready
[   12.118877] random: procd: uninitialized urandom read (4 bytes read)
[   13.068614] eth1: link up (1000Mbps/Full duplex)
[   13.073309] IPv6: ADDRCONF(NETDEV_CHANGE): eth1: link becomes ready
[   13.080445] IPv6: ADDRCONF(NETDEV_CHANGE): eth1.1: link becomes ready

Since the UDP message was sent prior to link becoming ready, it was
never seen on the wire.

The default failsafe timeout is set to 2 seconds, so with this patch
there are two attempts to send the message, one spent in vain, and the
other visible in tcpdump on an attached host. Of course, in cases when
the interface is brought up faster it leads to two messages, however it
should be harmless. This patch (almost) doesn't affect normal boot time
while still allowing to enter failsafe reliably with a single button
press, matching the official "generic failsafe" documentation.

a6fbdd3a78 base-files: don't store label MAC address in uci system config
If set, label MAC address is available from one of two sources,
device tree or board.json. So far, the function get_mac_label
was meant for retrieving the address, while an option in uci
system config was specified only for case 2 (board.json).

The uci config option has several drawbacks:
- it is only used for a fraction of devices (those not in DT)
- label MAC address is a device property, while config implies
  user interaction
- label_macaddr option will only be set if /etc/config/system
  does not exist (i.e. only for new installations)

Thus, this patch changes the behavior of get_mac_label:
Instead of writing the value in board.json to uci system config
and reading from this location afterwards, get_mac_label now
extracts data from board.json directly. The uci config option
won't be used anymore.
In addition, two utility functions for extraction only from DT
or from board.json are introduced.

Since this is only changing the access to the label MAC address, it
won't interfere with the addresses stored in the code base so far.
