Bug#1056406: linux-image-6.1.0-13-amd64: Rule traversal error in the routing table



Package: src:linux
Version: 6.1.55-1
Severity: important

Dear Maintainer,

The issue is that IPv4 routing entries (in kernel routing tables) are processed incorrectly, unless a tweak is done in the priority of processing of the routing tables. The tweak (described in the end) helps to fix the issue, but the issue comes back once the computer is rebooted. The situation is reproduced in Debian 11, 12 (and not in Debian 10).

Reproduction scenario.
I need to add a network 203.0.113.0/24 to the blackhole.

First, I check the priority of processing of the routing tables. It is configured by default so:
root@computer:~# ip rule show
0: from all lookup local
32766: from all lookup main
32767: from all lookup default

Below are the routes related either to the default gateway or the network 203.0.113.0/24 in the main table before the experiment.
root@computer:~# ip r show table main | grep -e '203\|default'
default via 185.50.156.1 dev enp4s0 proto dhcp src 185.50.159.149 metric 1024

The default gateway is OK. The network 203.0.113.0/24 is not there in the table, that is also OK.
Checking the routing to the 203.0.113.0/24 network before starting the experiment:
root@computer:~# ip r get 203.0.113.1
203.0.113.1 via 185.50.156.1 dev enp4s0 src 185.50.159.149 uid 0 cache

OK, the network is routed to the default gateway from the main table.
I add a blackhole route to the main table:
root@computer:~# ip r add blackhole 203.0.113.0/24

Checking the entries in the main table that are relevant to the experiment:
root@computer:~# ip r show table main | grep -e '203\|default'
default via 185.50.156.1 dev enp4s0 proto dhcp src 185.50.159.149 metric 1024
blackhole 203.0.113.0/24

Checking how the 203.0.113.0/24 network is routed:
root@computer:~# ip r get 203.0.113.1
RTNETLINK answers: Invalid argument

Great, the route leads into the blackhole.
Then I add the default route, which is supposed to have no effect on the network routing rules, to the default table the same way as it was done to the main table. The default table was empty before the experiment, and its priority is lower:
root@computer:~# ip r add default via 185.50.156.1 dev enp4s0 proto dhcp src 185.50.159.149 metric 1024 table default

It is expected that the network 203.0.113.0/24 is routed to the blackhole route as before (as set in the main table).

Checking:
root@computer:~# ip r get 203.0.113.1
203.0.113.1 via 185.50.156.1 dev enp4s0 table default src 185.50.159.149 uid 0 cache

Problem: the blackhole route in the main table stopped working, although it is listed in there. Instead, the routing of the default table was used.

Proposed workaround:
1. Add a little non-impacting rule which would lead to the main table (the processing rule with priority 32766 is still there, as it was there before the experiment):
root@computer:~# ip rule add lookup main pref 32000

This helps to eliminate the problem, but only until the computer is rebooted.

2. The rule with priority 32000 can be deleted.
root@computer:~# ip rule del lookup main pref 32000

The idea is that you kind of do a «touch» to the «ip rule» table, and — magically — this fixes the processing of the entries.
