Hi Diamian,

There shouldn’t be any critical sections in an ips options. The current threading model places 1 interface set / pcap per thread, so threads shouldn’t need to share any data with each other. What global data are you trying to share?

Subject: [Snort-devel] Multi threading in ips_options

How does multi threading work in Snort 3? I mean - i made IPS Option and I want it to be stateful (as in use global data shared amongst all ips option instances). However from what I saw in manual Snort 3 support multi threading. So how do I handle critical sections in IPS Option module code? Can I just use pthread mutexes? Or is there some other recommended way?

Best regards
Damian Chilinski
