My reasons to vote to keep it
1. Strongswan implemented nflog after we did.So I am guessing it has some
2. AFIK : It is low footprint code and no reported security issues with it,
or going stale with older versions kernel or user space. Low maintance so
why throw it?
3. I do not think xfrm interface is an exact replacement for nflog. NFLOG
give access to different parts of the stack. I am not sure xfrm interface
will get all traffic such as clear traffic or block. In some cases it may
appear to get it, but not necessary.
