Yunseong Kim bab4923132 tracing/net_sched: NULL pointer dereference in perf_trace_qdisc_reset() 
In the TRACE_EVENT(qdisc_reset) NULL dereference occurred from

 qdisc->dev_queue->dev <NULL> ->name

This situation simulated from bunch of veths and Bluetooth disconnection
and reconnection.

During qdisc initialization, qdisc was being set to noop_queue.
In veth_init_queue, the initial tx_num was reduced back to one,
causing the qdisc reset to be called with noop, which led to the kernel
panic.

I've attached the GitHub gist link that C converted syz-execprogram
source code and 3 log of reproduced vmcore-dmesg.

 https://gist.github.com/yskelg/cc64562873ce249cdd0d5a358b77d740

Yeoreum and I use two fuzzing tool simultaneously.

One process with syz-executor : https://github.com/google/syzkaller

 $ ./syz-execprog -executor=./syz-executor -repeat=1 -sandbox=setuid \
    -enable=none -collide=false log1

The other process with perf fuzzer:
 https://github.com/deater/perf_event_tests/tree/master/fuzzer

 $ perf_event_tests/fuzzer/perf_fuzzer

I think this will happen on the kernel version.

 Linux kernel version +v6.7.10, +v6.8, +v6.9 and it could happen in v6.10.

This occurred from 51270d573a. I think this patch is absolutely
necessary. Previously, It was showing not intended string value of name.

I've reproduced 3 time from my fedora 40 Debug Kernel with any other module
or patched.

After applying our patch, I didn't find any kernel panic errors.

We've found a simple reproducer

 # echo 1 > /sys/kernel/debug/tracing/events/qdisc/qdisc_reset/enable

 # ip link add veth0 type veth peer name veth1

 Error: Unknown device type.

However, without our patch applied, I tested upstream 6.10.0-rc3 kernel
using the qdisc_reset event and the ip command on my qemu virtual machine.

This 2 commands makes always kernel panic.

Yeoreum and I don't know if the patch we wrote will fix the underlying
cause, but we think that priority is to prevent kernel panic happening.
So, we're sending this patch.
