Subject: [PATCH 5.10 023/102] netfilter: nftables: add nft_parse_register_store() and use it
From: Pablo Neira Ayuso <pablo@...filter.org>
[ Upstream commit 345023b0db315648ccc3c1a36aee88304a8b4d91 ]
This new function combines the netlink register attribute parser
and the store validation function.
This update requires to replace:
enum nft_registers dreg:8;
in many of the expression private areas otherwise compiler complains
with:
error: cannot take address of bit-field ‘dreg’
when passing the register field as reference.
