It is possible for the system to run out of memory when dealing
with large file uploads and installs.
As part of the upgrade procedure shutdown services that are not
essential for node operations to allow more memory for install
to take place.
Includes changes to linkled to indicate this new state as it will
be shutdown as part of the cleanup process.
Memory gain (approximate)
dropbear 100kb
linkled 200kb
logd 200kb
odhcp 100kb
snmpd 500kb
xinetd 100kb
Total(approximate): 1200kb (around %4 on 32mb devices)
This is somewhat similar to files/usr/local/bin/upgrade_kill_prep
except that it kills only a select group of services
so that the system can handle the file upload while
upgrade_kill_prep does the final system cleanup to run the full
upgrade.

RFC requires that the DHCP server include the default gateway (0.0.0.0/0) route as part the Classless network list.
Moved to node-setup so it can be set dynamically at setup run time.
fixes AREDN->ticket:155
Due to a firewall chain name changes in BB when a node was in NAT mode (instead of recommended direct mode) connections that went out over DTDLink as the first hop would not be masqed and as such would not work.
This changes the beacon rate from once every 100tu's to once every 500tu's
1tu=1024 microseconds
This will decrease the amount of RF time being used by beacon packets.
This is especially important on 900MHz and 2.4GHz using 5MHz wide channels where 10 nodes beaconing 10x a second at ~256kbit/s can use up around 45% of the RF channel in beacons alone.
Other bands and channels and widths are not expected to see as significant an advantage due to the faster data rates.
This adds support for 802.11n data rates on the mesh.
This should improve dataspeeds across the board
MIMO devices like Rocket and NanoStation should be able to use dual chains which allows diverse data transmission on each chain increasing throughput
MCS data rates in theory should cut through noise better than legacy modulation and have higher speeds on each step which should allow overall higher datarate between nodes.
Merging in latest release-3.15.1.0 changes into develop to provide a foundation with recent release fixes for the develop branch.
This should be 3.15.1.0b03 code.

We don't really need any files in there, and keeping the folder can interfere with the programs that populate /etc/aredn_include on firstboot from uci-default.
This will cause the node to boot up in default mode (with an AP on its interface on the default channels) during its first boot, and than very quickly reboot and come up under the mesh.
Not getting much debug information at moment, would like to put this in uci-defaults but with issues that I can't seem to log at moment (and not having serial cable for this device) I'm going with lets put it in /etc/init.d/local before nvram and similar gets set.

Old code would set mac on the sub-vlan not the master interface which could cause issues.

Firewall rules don't get called because vtund is at /usr/sbin/vtund not /usr/bin/vtund
Also make the check if line posix compatible while we are chaning the path to be sure it works in the future too.
Remove the chmod step inside of setup.
Came across one time where this didn't trigger.
In addition this saves us from using additional storage space on the node as a +x creates a duplicate file.
wifi detect is called in /etc/init.d/boot before uci_apply_defaults is called.
Because of this if we don't have the data about the radio0path we need to remove the wifi config file first before calling wifi detect.
Needs to be in uci-defaults to be sure these data sets execute BEFORE the OS boots
We also need to get radio0 path because its mandatory for wifi to work.
Needed for sysupgrade from 3.0.2 to latest version.
Allows nodes to default to a common channel that is in the most common bandplan space for Part 97 usage.
Local cordination is still needed by users to make sure the channel matches the local deployment.
Defaults are as follows:
Band : Channel Freq : Bandwidth
900 : 912MHz : 5MHz
2400 : 1 2412MHz : 20MHz
3400 : 3420MHz : 5MHz
5800 : 149 5745MHz : 5MHz
2.4GHz keeps channel 1 at 20MHz because it is the standard deployment.
All other bands are still 'new' and no standard exist so we are creating one.
5MHz chosen because it better fits the emcomm goal. Smaller width should be stronger allowing for better networks.
Local networks can change as they see fit.
Remove setting RF channel on first boot in uci-defaults.
This should allow the node to use standard wifi channels when it boots allowing mesh setup to be run from a laptop or mobile device.
We will later move them to a real mesh channel during the mesh setup page.
Should also resolv issue where nodes were booting up on channel -2 and similar and wifi would refuse to start due to regdomain.
Config file is present upon initial start and in mesh mode.
Daemon still starts up in other modes but will not function w/o settings.
Firewall:
Permit access for UDP:161 (SNMPD) on WIFI and DTDLINK
Lan is permitted by default allow rules.
Makes the nodes advertise using DHCP Options 121 and 249 routes to the mesh (10.0.0.0/8) and the reserved (172.16.0.0/12) address ranges.
This change allows directing systems to prefer the mesh node for mesh ranges unless another network rule is more specific (such as a directly connected network)
This is mostly useful where a PC may have multiple network connections active as it improves the desire for the packets to travel via the mesh network.
Currently the:
10.0.0.0/8 range is used by mesh nodes and dtdlinking of mesh nodes.
172.27.0.0/16 is used for default LAN network on NAT nodes.
172.33.0.0/16 is for ad-hoc tunnels
All others in the advertised range are reserved for future network use.
Under Barrier Breaker sometimes OLSRD gets started before any interface is up causing OLSRD to shutdown because no interfaces exist.
Forces OLSRD to stay on and wait for the interfaces to come online.
Nodes sometimes show up as a mid1 entry when dtdlink and RF connected.
Sometimes the nodes will get the eth0 ip because wlan0 is not up yet.
Under Barrier Breaker the MainIP option is now supported as part of the uci system which allows us to restore using this setting.
We can now force the IP address that is claimed (wlan0) for the primary IP of the node.
Since a large number of the BBHNDev team has decided to create firmware fully independent of the BBHN Project the decision has been made to rebrand the firmware to differentiate from the origional BBHN work.
We would like to thank all those whom have worked on the BBHN firmware over the years and all those who continue to work on the firmware under AREDN(TM).
When a non mesh-gw node has a route via the WAN interface and through a mesh-gw it will choose the mesh-gw instead of the local WAN connection.and
We change the routing list to prefer the WAN link.
When the WAN is static configured the user will need to disable the WAN interface for the mesh internet to be chosen.
When the WAN is configured to dynamic the loss of a DHCP lease will allow the node to chose the remote mesh internet.
The simple solution would be to change the WAN to disabled and reboot to ensure a remote node is used instead if the local internet fails.
Thanks to Joe AE6XE and Clint AE5CA for pointing out this scenario.
By checking the "Keep Settings" box the node will run sysupgrade instead of mtd. Core settings are stored between installs and the _setup files are updated by pulling in missing items from the _setup.default files.
Using a press of around 5 seconds (3-7) the node will reset the passord to BBHN default and enable dhcp on the lan interface.
A press of around 10 seconds (8-12) will cause the node to reset the node to 'just flashed' status and cause the node to reboot.
Due to multiple issues that olsrd secure seems to make occur more often (but is not soley caused by OLSR Secure) causing olsr to crash olsr secure is being pulled while we work on the module.
This partialy reverts commit 553c126490.

Required for 900mhz devices to be supported due to band size.
This can also be useful for allowing more devices to fit into the same amount of RF space as nodes may often not need full 20mhz wide channels.

In order to maintain compatibility with existing deployed nodes, known common encrypted ports will NOT be blocked by default.
Users will receive a message during first setup encouraging them to review the rules that apply to how they intend to use their node and that laws very by country and frequency.
A package blockknownencrypted has been created in changeset:123a521df2b63ba1c5bdd6ad94ac402b86394579/bbhn_packages to be used in blocking known encrypted ports if the user feels it is necessary.
As developers we are not stating an opinion as to what the rules say or do not say in relationship to the traffic this deals with. Each user will need to make their own determination of the rules.
This has been the current case since day one.
New file fwinfo page shows if the package is installed AND displays the active firewall rules at the time of the access. This allows future grown to help test (because of the adhoc nature of the mesh) if packet filtering is the cause of a connection not working.
