Running your firewall's "wan" zone in REJECT zone (1) exposes the
presence of the router, (2) depending on the sophistication of
fingerprinting tools might identify the OS and release running on
the firewall which then identifies known vulnerabilities with it
and (3) perhaps most importantly of all, your firewall can be
used in a DDoS reflection attack with spoofed traffic generating
ICMP Unreachables or TCP RST's to overwhelm a victim or saturate
his link.
This rule, when enabled, allows traceroute to work even when the
default input policy of the firewall for the wan zone has been
set to DROP.

The current implementation is significantly lowering lantiq
performace [1][2] by using RPS with non-irq CPUs and XPS
with alternating CPUs.
The previous netifd implementation (by default but could be
configured) simply used all CPUs and this patch essentially
reverts to this behaviour.
The only document suggesting using non-interrupt CPUs is Red
Hat [3] where if the network interrupt rate is extremely high
excluding the CPU that handles network interrupts *may* also
improve performance.
The original packet steering patches [4] advise that optimal
settings for the CPU mask seems to depend on architectures
and cache hierarcy so one size does not fit all. It also
advises that the overhead in processing for a lightly loaded
server can cause performance degradation.
Ideally, proper IRQ balancing is a better option with
the irqbalance daemon or manually.
The kernel does not enable packet steering by default, so
also disable in OpenWRT by default. (Though mvebu with its
hardware scheduling issues [5] might want to enable packet
steering by default.)
Change undocumented "default_ps" parameter to clearer
"packet_steering" parameter. The old parameter was only ever
set in target/linux/mediatek/base-files/etc/uci-defaults/99-net-ps
and matched the default.

Prepare netifd for handling procd service jails having their own
network namespace.
Intefaces having the jail attribute will only be brought up inside the
jail's network namespace by procd calling the newly introduced ubus
method 'netns_updown'.
Currently proto 'static' is supported and configuration changes are
not yet being handled (ie. you'll have to restart the jailed service
for changes to take effect).
Example /etc/config/network snippet:
config device 'veth0'
option type 'veth'
option name 'vhost0'
option peer_name 'virt0'
config interface 'virt'
option type 'bridge'
list ifname 'vhost0'
option proto 'static'
option ipaddr '10.0.0.1'
option netmask '255.255.255.0'
config interface 'virt0'
option ifname 'virt0'
option proto 'static'
option ipaddr '10.0.0.2'
option netmask '255.255.255.0'
option gateway '10.0.0.1'
option dns '10.0.0.1'
option jail 'transmission'

When ASLR_PIE was activated globally these drivers failed to build
because the user space LDFLAGS leaked into the kernel build process.
This was fixed in upstream Linux kernel commit ce99d0bf312d ("kbuild:
clear LDFLAGS in the top Makefile") which went into Linux 4.17. The
lantiq target is now on Linux 4.19 only and these exceptions are not
needed any more.

I've removed service_running from netifd/network init script as well,
because it was not working properly, looked quite strange and I didn't
understand the intention:
$ /etc/init.d/network stop
$ service network running && echo "yes" || echo "nope"
( have to wait for 30s )

509e673 firewall3: Improve ipset support
The enabled option did not work properly for ipsets, as it was not
checked on create/destroy of a set. After this commit, sets are only
created/destroyed if enabled is set to true.
Add support for reloading, or recreating, ipsets on firewall reload. By
setting "reload_set" to true, the set will be destroyed and then
re-created when the firewall is reloaded.
Add support for the counters and comment extensions. By setting
"counters" or "comment" to true, then counters or comments are added to
the set.
