[PATCH net-next 0/7] netfilter updates for net-next

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

This series contains initial netfilter skb drop_reason support, from
myself.

First few patches fix up a few spots to make sure we won't trip
when followup patches embed error numbers in the upper bits
(we already do this in some places).

Then, nftables and bridge netfilter get converted to call kfree_skb_reason
directly to let tooling pinpoint exact location of packet drops,
rather than the existing NF_DROP catchall in nf_hook_slow().

I would like to eventually convert all netfilter modules, but as some
callers cannot deal with NF_STOLEN (notably act_ct), more preparation
work is needed for this.

Last patch gets rid of an ugly 'de-const' cast in nftables.
