Browse files Browse the repository at this point in the history
The code for frame diverter is unmaintained and has bitrotted.
The number of users is very small and the code has lots of problems.
If anyone is using it, they maybe exposing themselves to bad packet attacks.

What: frame diverter
When: November 2006
Why: The frame diverter is included in most distribution kernels, but is
broken. It does not correctly handle many things:
- IPV6
- non-linear skb's
- network device RCU on removal
- input frames not correctly checked for protocol errors
It also adds allocation overhead even if not enabled.
It is not clear if anyone is still using it.
