Hello sir,I wanted to clarify on some concepts in firewall hooks. I found FW_QUEUE as a return type in firewall hook functions in some codes which use firewall hooks. I wanted to know the significance of FW_QUEUE. When is this used as a return type in firewall hook functions ??
In the tcp/ip code for kernel 2.2.20, in ip_output.c; one of the comments says that when call_out_firewall returns FW_QUEUE silently drop the skb.
Can you please elaborate on this. Thanks in advance Regards Puja Puri
