Both are now implemented by nf_nat_masquerade.c, so no need to keep
different headers.

netfilter: nf_tables: merge route type into core

2019-04-08T21:01:42+00:00

very little code, so it really doesn't make sense to have extra
modules or even a kconfig knob for this.

Merge them and make functionality available unconditionally.
The merge makes inet family route support trivial, so add it
as well here.

netfilter: ip6t_srh: fix NULL pointer dereferences

2019-03-18T15:22:48+00:00

skb_header_pointer may return NULL. The current code dereference
its return values without a NULL check.

The fix inserts the checks to avoid NULL pointer dereferences.

netfilter: nf_tables: merge ipv4 and ipv6 nat chain types

2019-03-01T13:36:59+00:00

Merge the ipv4 and ipv6 nat chain type. This is the last
missing piece which allows to provide inet family support
for nat in a follow patch.

The kconfig knobs for ipv4/ipv6 nat chain are removed, the
nat chain type will be built unconditionally if NFT_NAT
expression is enabled.

netfilter: nf_tables: nat: merge nft_masq protocol specific modules

The family specific masq modules are way too small to warrant
an extra module, just place all of them in nft_masq.
