There are several long-standing issues present in the UCI shell API as
documented in https://wiki.openwrt.org/doc/devel/config-scripting. They
relate both to high-level, user-defined callback functions used to
process UCI config files, and also to low-level functions used within
scripts generally.
The related problems have been encountered now and in the past, e.g.
https://forum.openwrt.org/viewtopic.php?id=54295, and include:
a) UCI parsing option() function and user-defined option_cb() callbacks
being erroneously called during processing of "list" config file entries;
b) normal usage of the low-level config_set() unexpectedy calling any
defined option_cb() if present; and
c) handling of the list_cb() not respecting the NO_CALLBACK variable.
Root causes include a function stack "inversion", where the low-level
config_set() function incorrectly calls the high-level option() function,
intended only for processing the "option" keyword of UCI config files.
This change addresses the inversion and other issues, making the option
handling code more consistent and smaller, and simplifying developers'
usage of UCI callbacks.

Our commands setting accept_ra to 0 on all interfaces got lost in the
transition to procd. This remained unnoticed for a long time, as we also
enable forwarding on all interfaces, which prevents RA handling by default.
Restore the commands, while also fixing a possible race condition in the
old version.

We don't need two versions of this. The escaping quotes

it has nothing to do with the contents of the file, thus

Obviously not all GPIO controller allow to change the direction. The issue
is around since the beginning of the script but only due to the recent
changes error messages are more visible.
Add a check if a change of the direction is supported by the GPIO
controller and fallback to setting only the value if not.

Use the "low" and "high" values to configure the GPIO as an output with
that initial value. It ensures that the gpio doesn't have a unwanted value
during the time the direction is set to ouput and the actual value is
applied.
We don't need to take care of the GPIO polarity for now, since our
exported GPIOs are always active low.

To not clutter the system when building an opkg free image, generate the
distfeeds.conf only if CLEAN_IPKG is unset.
Since opkg is now a shared package, we can't rely on PACKAGE_opkg, but
since opkg is not reasonably usable without the status information, we
can tie the distfeeds.conf to it.

All the relevant options used for distfeeds.conf are part of base-files,

The /bin/config_generate script and some other scripts are assuming the
/etc/config directory exists in the image. This is true in case for
example the package firewall, dropbear or dnsmasq are included, which
are adding the files under /etc/config/. Without any of these package
the system will not boot up fully because the /etc/config/ directory is
missing and some init scripts just fail.
Make sure all images with the base-files contain a /etc/config/
directory.

Setting ipv6 to auto in case of a pppoe interface will trigger the
creation of a dynamic wan_6 interface meaning two IPv6 interfaces
(wan6 and wan_6) will be active on top of the pppoe interface.
This leads to unpredictable behavior in the network; therefore set
ipv6 to 1 which will prevent the dynamic creation of the wan_6
interface.
Further alias the wan6 interface on top of the wan interface for pppoe
as the wan6 interface can only be started when the link local address is
ready. In case of pppoe the link local address is negotiated during the
Internet Protocol Control Protocol when the PPP link is setup meaning
all the IP address info is only available when the wan interface is up.

Set sysctl fs.suid_dumpable = 2
This allows suid processes to dump core according to kernel.core_pattern
setting. LEDE typically uses suid to drop root priviledge rather than
gain it but without this setting any suid process would be unable to
produce coredumps (e.g. dnsmasq)
Processes still need to set a non zero core file process limit ('ulimit
-c unlimited' or if procd used 'procd_set_param limits
core="unlimited"') in order to produce a core. This setting removes an
obscure stumbling block along the way.
>From https://www.kernel.org/doc/Documentation/sysctl/fs.txt
suid_dumpable:
This value can be used to query and set the core dump mode for setuid
or otherwise protected/tainted binaries. The modes are
0 - (default) - traditional behaviour. Any process which has changed
privilege levels or is execute only will not be dumped.
1 - (debug) - all processes dump core when possible. The core dump is
owned by the current user and no security is applied. This is
intended for system debugging situations only. Ptrace is unchecked.
This is insecure as it allows regular users to examine the memory
contents of privileged processes.
2 - (suidsafe) - any binary which normally would not be dumped is dumped
anyway, but only if the "core_pattern" kernel sysctl is set to
either a pipe handler or a fully qualified path. (For more details
on this limitation, see CVE-2006-2451.) This mode is appropriate
when administrators are attempting to debug problems in a normal
environment, and either have a core dump pipe handler that knows
to treat privileged core dumps with care, or specific directory
defined for catching core dumps. If a core dump happens without
a pipe handler or fully qualifid path, a message will be emitted
to syslog warning about the lack of a correct setting.
