[Oisf-users] Can't apply BPF from file when PF_RING enabled? 2.1beta3

I’m experiencing some strange behavior with 2.1beta3. When I specify an external BPF file, the filter fails to apply. When I copy & paste the exact same filter from the file and insert it as the value in the YAML config, it works. The error is from the PF_RING integration code, so maybe it’s a unique condition to PF_RING support?

Error when filter is set to file:
7/2/2015 -- 18:24:48 - <Info> - Set PF_RING bpf filter "/etc/suricata/bpf.filter" failed.
