[PATCH v1 0/6] netlink netfilter decoder

[Mathis Marion]

From: Mathis Marion <mathis.marion at silabs.com>

Hello,

I have been using strace to analyze the nftables kernel API, and ended
up implementing some decoders. This is by no means complete, but I
included already quite a lot of attributes. I hope that the community
will find this valuable.

I manually tested this series using 'strace nft', but I am opened to
spend a bit of time on writing unit tests if necessary. Testing all
attributes seems unreasonable though so I am interested to know more
about the project's expectations.

Mathis Marion (6):
  netlink_netfilter: decode base attributes
  netlink_netfilter: decode expressions
  netlink_netfilter: decode set elements
  netlink_netfilter: decode enums and flags
  netlink_netfilter: decode counters
  netlink_netfilter: decode hooks
