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 bab933d ("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 <git@bitsofnetworks.org>
Changes:
* Fixed a bug that caused confustion between learned routes and
imported routes (thanks to Fabian Bläse).
* Fixed a bug that prevented install filters from being evaluated
(thanks to Killian Lufau).

This applies some style improvements to make this ready for migration to openwrt/packages. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
20 August 2019: babeld-1.9.1
* Fixed a crash that could happen when unicast and RTT estimation are
both enabled on an interface. Thanks to Dave Taht.
* Fixed compilation under BSD. Thanks to Dave Taht.
4 August 2019: babeld-1.9.0
* Reworked buffering of unicast packets to use a per-neighbour buffer
rather than a single buffer per interface. This makes unicast as
efficient as multicast, at the cost of slightly higher memory usage.
* Added option "unicast" that allows sending most TLVs over unicast.
This is necessary for the DTLS extension.
* Implemented parsing of unicast Hellos. This makes it possible to
interoperate with neighbours that only speak unicast (e.g. over some
kinds of tunnels that only do unicast).
* Implemented sending of unscheduled unicast Hellos. This makes the
RTT extension work over unicast too.
* Reworked the xroute data structures to use binary search and
linear-time comparison.
* Don't attempt to modify the rp_filter sysctl if it already has the
desired value; this makes it possible to run babeld in an
unpriviledged container. Thanks to Christof Schulze.
* Reinstated logging of late hellos. Thanks to Dave Taht.
* Don't send wildcard requests or Hellos to newish nodes. This makes
acquisition of new neighbours slower, but drastically reduces noise at
startup. Thanks to Teco Boot.
* Remove an arbitrary limit on the number of interfaces. Thanks to
Christof Schulze.
* Removed class E from martian filter. Thanks to Dave Taht.
* Added the ability to set the preferred source address in install filters.
Thanks to Killian Lufau.
* Fixed a number of read-only buffer overflows. Thanks to Leo Stefanesco.

@adrianschmutzler err, I don't understand, what does this has to do with babeld? |
|
@zorun It has nothing to do with babel. I just posted here, because I saw that you own a ZBT WE3526, and the PR was closed anyway. |

@adrianschmutzler ah, got it |
