This looks strange.
The BUG in slab.c tells us that there is a GFP_ATOMIC missing. This means that
we are allocating kernel memory from softirq context with only GFP_KERNEL.
If I understand your backtrace correctly, what happens is:
- you are reloading a ruleset via setsockopt() from userspace
- the kernel then suddenly receives a packet and processes it (because the stack
shows ip_conntrack code)
- after resuming the sockopt, it tries to allocate the new memory and fails.
but allocation of the memory happens in syscall context... why would it need
