[PATCH] batctl: neighbor: Fix print neighbors table header
by noahbpeterson1997＠gmail.com 09 Sep '24

09 Sep '24

netlink_print_neighbors() now prints the correct header to match what batman-advanced currently outputs. The examples in the README.rst are updated too.

[PATCH] alfred: add more verbose error message
by noahbpeterson1997＠gmail.com 09 Sep '24

There is an issue with some Linux distributions (Raspian) where network interfaces are up and active, but do not have the correct link-local address. This condition is now checked and output to stderr to better help users troubleshoot this issue.

Re: bat0 not capable of MTU > 1500
by Rich Chase 03 Sep '24

I am trying to create an unimpeded path MTU of 1500 on my OpenWRT router (Belkin RT-3200). I built the firmware from git Master, with kernel version 6.1, and batman-adv version 2023.2. I have a batmesh hard-if device mastering an 802.1S mesh, which are both set to MTU=2304. Using Luci (OpenWRT web gui for uci), I set the MTU of bat0 to 1504 to accommodate .1q vlans on bat0 -- bat0.5, bat0.110, etc. I see in the system log: kern.err kernel: [751585.375855] bat0: mtu greater than device maximum Also, if I do: #> ip link set bat0 mtu 1504 I get: ip: SIOCSIFMTU: Invalid argument and if I test: #> ip link show bat0 ...it says that my mtu is 1500 still. For my life I can't see anything I'm doing wrong. Why can't bat0 have MTU greater than 1500? I don't have any other devices mastered by bat0, other than my .1s wifi mesh link. Throwing myself at your mercy. Help?
