 emily | which I'm sure is a failure of my own searching, but you seem to know more about this than me, so… :) | 13:27:47 |

 K900 | @emily did your 320mhz change get merged | 17:45:59 |
| emily | no response yet | 18:59:08 |
| emily | it was only for GB though | 18:59:14 |
| emily | not sure about kernel list etiquette re: how long to wait before bumping it | 18:59:26 |
| K900 | Yeah I was thinking maybe I should send in the RU one but decided I don't actually care enough | 19:00:04 |

 ortolanbunting3002 | I have the following routes:
default via 192.168.1.1 dev wlan0 proto dhcp src 192.168.1.147 metric 3003
192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.100 dead linkdown
192.168.1.0/24 dev wlan0 proto dhcp scope link src 192.168.1.147 metric 3003
I have the following sysctl settings:
"net.ipv4.conf.all.ignore_routes_with_linkdown" = 1;
"net.ipv4.conf.default.ignore_routes_with_linkdown" = 1;
From the kernel docs: Ignore routes whose link is down when performing a FIB lookup.
% ip r g 192.168.1.1
192.168.1.1 dev wlan0 src 192.168.1.147 uid 1000
cache
%
eth0 is unplugged. Ping packets to 192.168.1.1 leave and arrive on wlan0 correctly. Despite that, the nixos-fw rpfilter chain drops those packets (checkReversePath = "strict", logReversePathDrops = true).
The relevant reverse path filter rule is fib saddr . mark . iif oif exists accept.
If I remove the routes on eth0, the pings are no longer dropped.
Why does routing work correctly, but the reverse path lookup fails?

 Ramses 🇵🇸 | I have the stable-privacy addressing method configured for all my networks with networkd, and I recently noticed that for one particular interface, this setting is not being honoured, and the interface still uses eui64. I checked that the right values are actually set in /proc/sys/net/ipv6/conf/<iface>/addr_gen_mode so it seems that networkd is doing what it's supposed to be doing, but the kernel isn't. One characteristic of this particular interface, is that it has a bunch of tagged vlan interfaces stacked on top of it, which is kind of the only thing that makes it stand out from the other interfaces. I was just wondering if anyone has by any change already stumbled upon this behaviour and looked into it? And if others are observing the same behaviour? | 11:23:18 |
| Ramses 🇵🇸 | Ah, I am talking about the LL addresses specifically here | 11:26:12 |
