... with ipv4/v6 nat now provided directly via nf_nat.ko.
Also changes:
ret = nf_nat_ipv4_fn(priv, skb, state);
if (ret != NF_DROP && ret != NF_STOLEN &&
into
if (ret != NF_ACCEPT)
return ret;
everywhere.
The nat hooks never should return anything other than
ACCEPT or DROP (and the latter only in rare error cases).
The original code uses multi-line ANDing including assignment-in-if:
if (ret != NF_DROP && ret != NF_STOLEN &&
!(IPCB(skb)->flags & IPSKB_XFRM_TRANSFORMED) &&
(ct = nf_ct_get(skb, &ctinfo)) != NULL) {
I removed this while moving, breaking those in separate conditionals
and moving the assignments into extra lines.
checkpatch still generates some warnings:
1. Overly long lines (of moved code).
Breaking them is even more ugly. so I kept this as-is.
2. use of extern function declarations in a .c file.
This is necessary evil, we must call
nf_nat_l3proto_register() from the nat core now.
All l3proto related functions are removed later in this series,
those prototypes are then removed as well.
v2: keep empty nf_nat_ipv6_csum_update stub for CONFIG_IPV6=n case.
v3: remove IS_ENABLED(NF_NAT_IPV4/6) tests, NF_NAT_IPVx toggles
are removed here.
v4: also get rid of the assignments in conditionals.

Open vSwitch is a multilayer Ethernet switch targeted at virtualized
|
|
environments. In addition to supporting a variety of features
|
|
expected in a traditional hardware switch, it enables fine-grained
|
|
programmatic extension and flow-based control of the network. This
|
|
control is useful in a wide variety of applications but is
|
|
particularly important in multi-server virtualization deployments,
|
|
which are often characterized by highly dynamic endpoints and the
|
|
need to maintain logical abstractions for multiple tenants.
|
|
|
|
The Open vSwitch datapath provides an in-kernel fast path for packet
|
|
forwarding. It is complemented by a userspace daemon, ovs-vswitchd,
|
|
which is able to accept configuration from a variety of sources and
|
|
translate it into packet processing rules.
|
|
|
|
See http://openvswitch.org for more information and userspace
|
|
utilities.
