Hi,
I'm trying to understand the difference between BPF, eBPF and netfilter. I
understand that BPF is a packet filter, but it appears to not be strictly
for firewalls, in the way that netfilter/iptables is?
It appears that applications like firewall-cmd, ipfire, etc are using
netfilter, but I also see references to other firewalls using BPF.
Any help to understand these differences and relationships would be
appreciated.
Wikipedia has a nice discussion/history of eBPF.
here's a snippet:
"eBPF evolved from the Berkeley Packet Filter as an extended version,
but its use case outgrew networking"
