robin-mesh-v2's Issues

Add zram-swap support

The zram-swap package, currently in trunk, allows the creation of a compressed swap device at /dev/zram0.
https://dev.openwrt.org/changeset/35025/

Members of openwrt-devel seem quite keen on using this, along with the author of this presentation:
http://wiki.freifunk.net/images/7/73/Vortrag.pdf

Backport zram-swap to AA to permit swap usage, i.e. better conservation of available RAM.

Reduce swappiness

zram active on all nodes, but recommend tweaking the 'swappiness' valueto 0 - the default is 65. the higher the number, the more likely the kernel swaps out. if set to 0 zram is only used if the is no other possibility. of course: if swapping begins, the box freezes for some
seconds but it does not die.

the kernel likes to swap out processes which are not in use, e.g. uhttpd or dropbear. olsrd or other active processes are very unlikely to be swapped - the kernel is smart somehow 8-)

Enable custom.sh download via SSL

Using existing curl tool to allow downloading of custom.sh via SSL instead of HTTP (gated by a config parameter).

SquashFS boot problems on Engenius EOC-1650/EOC-2611P

A regression from Backfire, the current gpiolib implementation in Attitude Adjustment interferes with boot on Engenius EOC-1650/EOC-2611p, et al. This ticket tracks the current patch:
https://dev.openwrt.org/ticket/11969

Restore soft reboot to Engenius EOC-1650/EOC-2611P

The /sbin/reboot command is set to toggle the wrong GPIO, and consequently soft reboot doesn't work on Engenius EOC-1650/EOC-2611P radios since at least Backfire. This ticket tracks current patch:
https://dev.openwrt.org/ticket/6202

Switch from uhttpd to mini_httpd or busybox httpd

Check if mini_httpd or busybox httpd with haserl is a better choice over uhttpd with conventional lua scripts.

Recovery behavior when gateway node is completely unavailable

Options for when a gateway node is completely unavailable:

• If no other stations detected on mesh, periodic restart wireless interface and/or /etc/init.d/networking. (Did have to restart wifi on TP-Link MR3020 after 5days uptime due to silent wifi driver failure.) This option does at least preserve active DHCP leases.
• If other stations detected on mesh but no gateway node, periodic restart of OLSRd?
• Or, periodic reboot of node?

Period for any such restart process should be quite long to avoid oscillation, e.g. 30min or 1hr.

Suppress redundant/dublicate syslog entries from busybox/crond

Default configuration for crond/busybox has all crontab entries logging to syslog, no matter what. This pollutes the syslog buffer when there are regularly scheduled tasks (e.g. once every 5min), and it gobbles up bandwidth needlessly when remote logging is used.

Allow specified entries in /etc/crontab/cron to NOT trigger entry to syslog.

Use short IBSS slot time in 5.8GHz band

This patch allows short slot times for IBSS beacons in 5.8GHz, while maintaining standards compliance. Observed maybe ~10% throughput improvement when tested with two Nanostation M5's set to 1000ms beacon internal. Radios set to shorter beacon interval would probably see more throughput improvement.

https://patchwork.kernel.org/patch/1835531/

This patch is not included in Attitude Adjustment, as of this writing.

Restart olsrd when gateway node internet access restored

Existing ROBIN mesh v2 checkin scripts can detect when internet service goes out (e.g. ping to 8.8.8.8). Something weird about olsrd on a gateway node seems to cause it to break repeater nodes' route to internet if the gateway node loses its own internet connection, but then gets it back shortly thereafter (1hr).

Workaround is to have ROBIN checkin scripts restart olsrd on gateway node after Internet outage resolved.

CONFIG_LEDS_GPIO prevents boot on OM1P

Enabling CONFIG_LEDS_GPIO appears to prevent boot from flash on OM1P running Attitiude Adjustment and current trunk. This ticket tracks the current patch.
https://dev.openwrt.org/ticket/13340

Move all temporary files to /tmp

Both ROBIN v3xxx and the initial version of ROBIN v2 write a bunch of stuff to the flash disk on a regular basis, e.g. to /etc/update, on a regular basis. This is bad. Relocate all temporary data associated with dashboard checkings to /tmp, and only write the following files to /etc:

/etc/robin_version
/etc/olsrd_version
/etc/reboot_reasons

Verify sane recovery when gateway node switches

Verify all repeater nodes correctly update their gateway route (and likewise correctly forward NAT-ed traffic) when OLSRd switches them to a new gateway node.

Use upstream for ping latency too

When using general.services.upstream and general.services.speedtest_url for speed test values, use the hostname embedded in speedtest_url for ping latency measurements as well.

Support newer 802.11n TP-Link products

TP-Link TL-WR1043ND
Looks like next step w/r/t comparable price point beyond TL-MR3420, also supports MIMO 3x3:3 w/ 3 antennas.

Having portal spoof Apple devices

Cloning relevant issue from Commotion-OpenWRT:
https://code.commotionwireless.net/issues/482

This line needs to be added to the pre-authenticated dnsmasq.conf file:

address=/apple.com/0.0.0.0

This will prevent apple devices and computers from auto authenticating splash screens (so folks who connect can see the local content we want to show over commotion splash).

When apple devices connect to a wifi spot, they auto-ping apple.com, but if the rule is changed to 0.0.0.0 for apple.com, it tricks the device into not auto authenticating. After authentication, the dnsmasq needs to remove this rule, otherwise apple.com will be completely inaccessible over the whole network...

Port IBSS-RSN support to wpad-mini

At present, IBSS-RSN encryption seems to require installing the full hostapd and wpa_supplicant packages, which are quite large (total ~420kBytes), and which include unneeded stuff like Enterprise WPA2 support. See about porting IBSS-RSN over to the smaller packages like wpad-mini.
