Johannes Kimmel 87d923c1ef fff-dhcp: increase dns cachesize
The default cachesize for dnsmasq is 150 entries, which results in a
poor cache hit rate.

Raise the default to 1024 to provide better cache hit rates on all
devices while still keeping memory usage in check.

Further increase the cachesize to 8192 entries for systems with enough
ram (currently more than 64MB).

The memory usage will increase roughly 100B per entry.

The size was chosen empirically. Higher values don't seem to increase
cache hit rate a lot.

Fabian Bläse a5ad4a9b00 fff-config: Set panic on OOM
The OOM killer does not make much sense on a router, because regardless
of which process is killed, most of the time some essential core
functionality is affected.

Set the panic on OOM sysctl, so every OOM leads to a kernel panic and
results in a reboot of the router, which restores a clean state.

Fabian Bläse 17bc1a7e62 fff-layer3-config: Always clear client interface list completely
Previously, some interfaces in the client ifname list have been kept.
The actual reason for this is unknown, it might have been used for the

Filtering the interface list in this way might lead to interfaces being

As it is not required anymore, remove the retention of some interfaces

Fabian Bläse 1c3328e64a Remove static configuration from dynamic script
Most of the configuration done in configurenetwork is static and does
not change after the first boot. Move this static configuration into a
uci-defaults script, which is only executed on first boot.

Configuration which might be changed at runtime (e.g. port assignment),
is kept in the configurenetwork script.

To improve readability and speed, combine multiple uci commands into a
uci batch. Drop any existing network configuration before applying our
own configuration. This requires the network.globals section to be
created explicitly. Also, the fdff:: addresses, ETHMESHMAC and ROUTERMAC
can be set unconditionally, as the uci-defaults script is only executed
once. Other than that, the static configuration has not been altered.

Adrian Schmutzler 27baecaf37 treewide: set PKG_RELEASE automatically
COMMITCOUNT allows to have the PKG_RELEASE calculated automatically
based on the number of commits for the package folder.

AUTORELEASE will count the number of commits since the last upstream
bump. This is relevant for packages with PKG_VERSION or
PKG_SOURCE_DATE set, but will not work for us since it assumes the
use of certain identifiers in commit titles.

COMMITCOUNT works fine for most of our packages, with the following
exceptions:

 * fff-nodewatcher would yield a commit count of 55, while the
   current PKG_RELEASE is 61. Thus, we do not touch it for now.

 * Packages that have been renamed will start counting from 1 after
   the rename, since folder renames are not tracked by git. This
   will result in descreasing PKG_RELEASE after the change for
   these packages.
   However, since moving essentially creates a new package anyway,
   counting from 1 makes sense conceptually, and PKG_RELEASE is
   still replaced for these packages.

 * alfred-json and fff-macnock use upstream code and thus would
   normally require AUTORELEASE. As discussed above, this will
   not work for us, so just leave these two untouched.

Note that all this is quite irrelevant for the way we use packages
currently, as without opkg PKG_RELEASE does not matter to us anyway.
So, let's just be happy about not having to bump PKG_RELEASE
anymore, while keeping the basic functionality intact.

The only package where the PKG_RELEASE is actually used for
something is fff-nodewatcher, where the version will be displayed
in the Monitoring.

For some purposes (e.g. SNAT, vxlan) it might be necessary to have an
additional address just for the router which is not attached to any

interface.

config to allow the user to configure such addresses. It is possible to
both specify the address with or without a subnet size.

The default configuration contains the IPv4 loopback address
(127.0.0.1/8) explicitly, but this is not necessary. These addresses are
configured automatically, even if they are not present in the
configuration, so they can safely be removed, if present.
