Is the libnetfilter_queue thread-safe?
Hi,
I would like to ask a question about the libnetfilter_queue. Is the libnetfilter_queue thread-safe? Would the API of libnetfilter_queue cause the kernel crash under multi-threading environment? I am using the Red Hat Enterprise Linux 5.2 with the kernel version 2.6.18-92.el5PAE to develop my own program. The version of libnetfilter_queue is 0.0.16 and the version of libnfnetlink is 0.0.40.
Thanks and Regards,
Jacky Luk

Is had yet to be decide :/ From my experience on NuFW, you can use it with multithreaded programs and you can have a reading thread and a writing thread working together on the same queue.

Clearly not, the worse that can happen is an application crash not a kernel crash.

I think it should be as long as you don't change anything related to the handle while using it. The remaining parts are merely a stateless communication mechanism, there's no reason why they shouldn't be thread-safe.
