Spontaneous reboot when connected to SIP service

[axelgenus]

Describe the bug

When I connect ISP Fritz!Box 5530 Fiber to my QNAP QHora 301W, running the latest snapshot from this repository, the router automatically reboots. It keeps rebooting as soon as the Fritz!Box tries reconnecting to the Internet.

I get the following error message in system.log:

Mon Apr 10 09:09:15 2023 kern.alert kernel: [ 2988.379674] Unable to handle kernel execute from non-executable memory at virtual address 0000000000000000

OpenWrt version

r22557+1-6a7cb3a925

OpenWrt target/subtarget

ipq807x/generic

Device

QNAP 301w

Image kind

Self-built image

Steps to reproduce

1. Let the QNAP boot up and settle.
2. Connect the Fritz!Box and power it up.
3. Wait for the Fritz!Box to connect to the Internet.

Actual behaviour

The router reboots immediately.

Expected behaviour

The two routers should play nice together.

Additional info

I only use the Fritz!Box as a SIP client.

It is definitely an issue with SIP protocol: also connecting to the SIP service by means of Linphone triggers a kernel panic and the device restart.

Wow very interesting, you just found either a null pointer dereference or a use-after-free (UAF) in the nf_conntrack_sip helper module, nice one! :)

I'd suggest disabling those nftable conntrack helper modules temporarily, I'll have a look at it but there are plenty of things to stabilize more urgently (such as the current broken Wi-Fi...).

Thanks for the report btw!
