babeld: add ubus bindings

2021-01-15T00:13:26Z

A better integration of babeld with OpenWrt is to connect the daemon to the IPC. So far, we can only communicate via a websocket. With ubus we can send and receive commands in json format. The commit adds a ubus interface to babeld with following functions: - get_info - get_neighbours - get_xroutes - get_routes All output is divided into IPv4 and IPv6. Ubus has to be enabled by setting "config general" option 'ubus_bindings' 'true' Example: root@OpenWrt:~# ubus call babeld get_info { "babeld-version": "babeld-1.9.2", "my-id": "32:xx:xx:xx:xx:xx:xx:xx", "host": "OpenWrt" } root@OpenWrt:~# ubus call babeld get_neighbours { "IPv4": { }, "IPv6": { "fe80::xx:xx:xx:xxx": { "dev": "br-lan", "hello-reach": 65408, "uhello-reach": 0, "rxcost": 96, "txcost": 96, "rtt": 4338271, "channel": -2, "if_up": true } } } root@OpenWrt:~# ubus call babeld get_xroutes { "IPv4": { "10.0.0.3/32": { "src-prefix": "0.0.0.0/0", "metric": 0 }, "10.0.0.0/24": { "src-prefix": "0.0.0.0/0", "metric": 0 } }, "IPv6": { "fdfa:xx:xx::1/128": { "src-prefix": "::/0", "metric": 0 } } } root@OpenWrt:~# ubus call babeld get_routes { "IPv4": { "10.2.0.1/32": { "src-prefix": "0.0.0.0/0", "route_metric": 96, "route_smoothed_metric": 96, "refmetric": 0, "id": "62:xx:xx:xx:xx:xx:xx:xx", "seqno": 41381, "channels": "", "age": 17, "via": "fe80::xx:xxxx:xxxx:xxxx", "nexthop": " nexthop ", "installed": true, "feasible": true }, "IPv6": { } } Additional IPC functionality will follow. Further, we changed the version to $version-ubus-mod. Signed-off-by: Nick Hainke

babeld: Update example configuration file

More example filters are provided, and new options such as "type" or "pref_src" are given as example. Signed-off-by: Baptiste Jonglez

babeld: Don't kill -9 on stop

2019-08-26T16:40:35Z

Killing anything with -9 is a bad idea. When killed this way, babeld won't be able to properly disassociate from its neighbours, withdraw its announced routes or remove routes from the kernel. This got introduced in bab933d4cad8 ("babeld: Update to version 1.8.3 + fix init") with an unrelated change. The purpose of the change is unclear because stopping and restarting babeld worked fine without this change. Signed-off-by: Baptiste Jonglez

babeld: Update to version 1.8.3 + fix init

2018-10-03T17:04:46Z

24 September 2018: babeld-1.8.3 * Fixed a read-only two byte buffer overflow in the packet parser. This is a read-only overflow, and hence most probably not exploitable. * Fixed an issue with creating unreachable routes on recent kernels (4.16 and up). Thanks to Christof Schulze. * Notice interface changes faster by listening to more netlink events. Thanks to Christof Schulze. * Fixed a local interface issue when an interface has no link-local address. Thanks to Christof Schulze. Also, the init script was edited to kill babeld on stop; restart works properly now, as well. Signed-off-by: Michael Adams

babeld: Cleanup old compatibility code in initscript

2017-01-15T23:13:15Z

It makes the init script more readable. It has been more than two years since babeld 1.5.1, let's hope nobody is still using the old (undocumented) option names. Incidentally, this commit fixes support for the "conf_dir" option, introduced by ac643416dc ("babeld: allow changing alternative configuration file and directory"). The default value of $OTHERCONFIGDIR was always used, because the variable was used *before* it was (possibly) redefined when parsing the UCI config. Signed-off-by: Baptiste Jonglez

babeld: add dynamic config files to the procd watch list

2017-01-09T16:07:40Z

This way, "/etc/init.d/babeld reload" will detect when one of these dynamic config files has changed, and restart babeld only if that is the case. Dynamic config files where introduced by 82d9002689 ("babeld: add support for dynamic config files"). Signed-off-by: Baptiste Jonglez

babeld: Log to the system log instead of logging to a file

2017-01-09T14:43:01Z

This avoids running out of flash or RAM space if babeld logs too much. The system log is stored on RAM by default and has a controlled size. It is still possible to tell babeld to log to a file, by using the following in /etc/config/babeld: config general option log_file "/var/log/babeld.log" Signed-off-by: Baptiste Jonglez

babeld: procd support

2017-01-09T14:37:52Z

note: dependant on openwrt commit 85fabd68, adding support for null arguments.

babeld: fix parsing of list import_table

2015-08-16T16:54:32Z

When parsing list options using config_load option_cb will be called with additional options ending in _ITEM$x and _LENGTH. This ignores any option containing _LENGTH or _ITEM as they can't possible be a valid babeld option making a config like config general list import_table 23 list import_table 42 work.
