OpenWrt uses a lot of (b)ash scripts for initial setup. This isn't the
best solution as they almost never consider syncing files / data. Still
this is what we have and we need to try living with it.
Without proper syncing OpenWrt can easily get into an inconsistent state
on power cut. It's because:
1. Actual (flash) inode and data writes are not synchronized
2. Data writeback can take up to 30 seconds (dirty_expire_centisecs)
3. ubifs adds extra 5 seconds (dirty_writeback_centisecs) "delay"
Some possible cases (examples) for new files:
1. Power cut during 5 seconds after write() can result in all data loss
2. Power cut happening between 5 and 35 seconds after write() can result
in empty file (inode flushed after 5 seconds, data flush queued)
Above affects e.g. uci-defaults. After executing some migration script
it may get deleted (whited out) without generated data getting actually
written. Power cut will result in missing data and deleted file.
There are three ways of dealing with that:
1. Rewriting all user-space init to proper C with syncs
2. Trying bash hacks (like creating tmp files & moving them)
3. Adding sync and hoping for no power cut during critical section
This change introduces the last solution that is the simplest. It
reduces time during which things may go wrong from ~35 seconds to
probably less than a second. Of course it applies only to IO operations
performed before /etc/init.d/boot . It's probably the stage when the
most new files get created.
All later changes are usually done using smarter C apps (e.g. busybox or
uci) that creates tmp files and uses rename() that is expected to be
atomic.

For now we have only kernel LED trigger support. With this change it is now
possible to use application triggers.
If we configure a LED with a non kernel trigger, then we check on every
restart and boot of the LED service if we have this trigger as an application
in "/usr/libexec/led-trigger". If this file with the name is found, then we
execute this to init the LED.
Possible use cases are:
- Start/Stop/Restart an application led trigger service for this led
- Init a LED that is configured by a hotplug script (VPN tunnel established)

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

More importantly, GPIO pins which are referenced by name will be immune
from pin mapping breakage while unintentional pin number changes are

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

The callback function receives two arguments when called, the config

returned by uci_validate_section().
This also updates several init scripts to use the new wrapper function.

Currently, the wifi detection script is executed as part of
the (early) boot process. Pluggable wifi USB devices, which
are inserted at a later time are not automatically
detected and therefore they don't show up in LuCI.
A user has to deal with wifi detection manually, or restart
the router.
However, the current "sleep 1" window - which the boot
process waits for wifi devices to "settle down" - is too
short to detect wifi devices for some routers anyway.
For example, this can happen with USB WLAN devices on the
WNDR4700. This is because the usb controller needs to load
its firmware from UBI and initialize, before it can operate.
The issue can be seen on a BT HomeHub 5A as well as soon as
the caldata are on an ubi volume. This is because the ath9k
card has to be initialized by owl-loader first. Which has to
wait for the firmware extraction script to retrieve the pci
initialization values inside the caldata.
This patch moves the wifi configuration to hotplug scripts.
For mac80211, the wifi configuration will now automatically
run any time a "ieee80211" device is added. Likewise
broadcom-wl's script checks for new "net" devices which
have the "wl$NUMBER" moniker.
Issues with spawning multiple interface configuration - in
case the detection script is run concurrently - have been
resolved by using a named section for the initial
configuration. Concurrent configuration scripts will now
simply overwrite the same existing configuration.
A workaround which preserves the "sleep 1" window for just
the first boot has been added. This allows the existing
brcm47xx boot and mvebu uci-default scripts to correctly
setup the initial mac addresses and regulatory domain.
And finally, the patch renames the "wifi detect" into
"wifi config". As the script no longer produces any output
that has to be redirected or appended to the configuration
file.
Thanks to Martin Blumenstingl for helping with the implementation
and testing of the patch.

Previously, wifi detect simply dumped its generated wireless
configuration to STDOUT. A second step was needed to append
the configuration to /etc/config/wireless (or create it, if
it didn't exist).
With this patch, The wifi detection script will now use uci
to update the wireless configuration directly.
This patch also makes the initially created wifi-iface a
named section ('default_radio$X' for mac80211 and
'default_wl$X' for broadcom). With this change, uci will
not print the cfgHASH to STDOUT (which would now corrupt
the wireless configuration). It will also prevent adding
duplicated wifi interface configurations, if the wifi
configuration is run concurrently.

We need to tell hwclock with -u commandline option, that we would like
to keep our RTC clock in UTC timezone. Linux kernel expects RTC in UTC
timezone anyway.
In current state of things, we don't tell hwclock to load/store time
from/to RTC in UTC timezone so it uses the timezone from the system
time. If it's set to different timezone then UTC, sysfixtime is going to
screw the time in RTC.
I've following in the setup script:
uci set system.@system[0].timezone='CET-1CEST,M3.5.0,M10.5.0/3'
uci set system.@system[0].zonename='Europe/Prague'
I've this RTC setup (rtc1 is RTC on i.MX6 SoC, rtc0 is battery backed RTC mcp7941x):
rtc-ds1307 3-006f: rtc core: registered mcp7941x as rtc0
snvs_rtc 20cc000.snvs:snvs-rtc-lp: rtc core: registered 20cc000.snvs:snvs-r as rtc1
Then we can experience following (current time is 10:15am):
$ date
Fri Oct 21 10:15:07 CEST 2016
$ hwclock -r -f /dev/rtc0
Fri Oct 21 08:14:46 2016 0.000000 seconds
$ hwclock -u -r -f /dev/rtc0
Fri Oct 21 10:14:46 2016 0.000000 seconds
And after current broken sysfixtime:
$ /etc/init.d/sysfixtime stop
$ date
Fri Oct 21 10:15:25 CEST 2016
$ hwclock -r -f /dev/rtc0
Fri Oct 21 10:15:31 2016 0.000000 seconds
Now we've time in our battery backed RTC in CEST timezone instead of
UTC. Then once again, but with this patch applied to sysfixtime, where
hwclock is using correctly the -u parameter:
$ /etc/init.d/sysfixtime stop
$ date
Fri Oct 21 10:15:53 CEST 2016
$ hwclock -r -f /dev/rtc0

dnsmasq maintains dnsmasq.time across reboots and uses it as a means of
determining if current time is good enough to validate dnssec time
stamps. By including /etc/dnsmasq.time as a time source for sysfixtime,
the mechanism was effectively defeated because time was set to the
last time that dnsmasq considered current even though that time is in
the past. Since that time is out of date, dns(sec) resolution would
fail thus defeating any ntp based mechanisms for setting the clock
correctly.
In theory the process is defeated by any files in /etc that are newer
than /etc/dnsmasq.time however dnsmasq now updates the file's timestamp
on process TERM so hopefully /etc/dnsmasq.time is the latest file
timestamp in /etc as part of LEDE shutdown/reboot.
Either way, including /etc/dnsmasq.time as a time source for
sysfixtime is not helpful.
