CVE-2024-50038: netfilter: xtables: avoid NFPROTO_UNSPEC where needed

In the Linux kernel, the following vulnerability has been resolved:

netfilter: xtables: avoid NFPROTOUNSPEC where needed

syzbot managed to call xtcluster match via ebtables:

WARNING: CPU: 0 PID: 11 at net/netfilter/xtcluster.c:72 xtclustermt+0x196/0x780 [..] ebtdotable+0x174b/0x2a40

Module registers to NFPROTOUNSPEC, but it assumes ipv4/ipv6 packet processing. As this is only useful to restrict locally terminating TCP/UDP traffic, register this for ipv4 and ipv6 family only.

Pablo points out that this is a general issue, direct users of the set/getsockopt interface can call into targets/matches that were only intended for use with ip(6)tables.

Check all UNSPEC matches and targets for similar issues:

- matches and targets are fine except if they assume skbnetworkheader() is valid -- this is only true when called from inet layer: ip(6) stack pulls the ip/ipv6 header into linear data area. - targets that return XTCONTINUE or other xtables verdicts must be restricted too, they are incompatbile with the ebtables traverser, e.g. EBTCONTINUE is a completely different value than XTCONTINUE.

Most matches/targets are changed to register for NFPROTOIPV4/IPV6, as they are provided for use by ip(6)tables.

The MARK target is also used by arptables, so register for NFPROTOARP too.

While at it, bail out if connbytes fails to enable the corresponding conntrack family.

This change passes the selftests in iptables.git.

  72. Configuration

    Register matches and targets that assume IPv4/IPv6 packet processing, including those incompatible with the ebtables traverser or relying on skb_network_header(), only for NFPROTO_IPV4 and NFPROTO_IPV6 instead of NFPROTO_UNSPEC.

    Linux netfilter xtables matches and targets NFPROTO_UNSPEC registration = NFPROTO_IPV4 and NFPROTO_IPV6
  73. Configuration

    Register the MARK target for NFPROTO_ARP as well as NFPROTO_IPV4 and NFPROTO_IPV6 because it is also used by arptables.

    Linux netfilter MARK target protocol-family registration = NFPROTO_IPV4, NFPROTO_IPV6, and NFPROTO_ARP
  74. Configuration

    Bail out when connbytes cannot enable the corresponding conntrack family.

    Linux netfilter connbytes corresponding conntrack family enablement = fail if enablement fails
