Subject: [PATCH v4 0/2] Drop IPV6 packets if IPv6 is disabled on boot
Date: Fri, 30 Aug 2019 15:13:52 -0300	[thread overview]
Message-ID: <20190830181354.26279-1-leonardo@linux.ibm.com> (raw)

This patchset was prevously a single patch named:
- netfilter: nf_tables: fib: Drop IPV6 packets if IPv6 is disabled on boot

It fixes a bug where a host, with IPv6 disabled on boot, has to deal with
guest IPv6 packets, that comes from a bridge interface.
When these packets reach the host ip6tables they cause a kernel panic.

---
Changes from v3:
- Move drop logic from nft_fib6_eval{,_type} to nft_fib_netdev_eval
- Add another patch to drop ipv6 packets from bridge when ipv6 disabled  

Changes from v2:
- Replace veredict.code from NF_DROP to NFT_BREAK
- Updated commit message (s/package/packet)

Changes from v1:
- Move drop logic from nft_fib_inet_eval() to nft_fib6_eval{,_type}
so it can affect other usages of these functions.

Leonardo Bras (2):
  netfilter: Terminate rule eval if protocol=IPv6 and ipv6 module is
    disabled
  net: br_netfiler_hooks: Drops IPv6 packets if IPv6 module is not
    loaded
