hi, i'm having some troubles to avoid race conditions between a netfilter function (in PRE_ROUTING hook) and a kernel thread. both share (for read and write) data structures created by the netfilter function, and only removed by the kernel thread. i've read "Unreliable Guide To Locking" and have the following questions: * what's the context in which run netfilter hooks? (maybe softirq?) * my development scenario is a UP with preempt enable, but the production scenario would be a SMP with preempt (that matters?) * what's the condition i don't know, thats 'freezes' the system? with spin_lock/unlock i'm getting total 'freeze' in some of the stress tests i run... what kind of locking i need to use instead? thanks in advance, toni -- toni <agar9938@xxxxxxxxxxxxxxxxxx> -- Kernelnewbies: Help each other learn about the Linux kernel.
