Storte the value of net_ipvs in a variable named ipvs so that when there are more users struct netns_ipvs in ip_vs_in_cmp and ip_vs_in_icmp_v6 they won't need to compute the value again. Signed-off-by:

Use the address of ipvs not the address of net when computing the hash value. This removes an unncessary dependency on struct net. Signed-off-by:

In practice struct netns_ipvs is as meaningful as struct net and more useful as it holds the ipvs specific data. So store a pointer to struct netns_ipvs. Update the accesses of param->net to access param->ipvs->net instead. In functions where we are searching for an svc and filtering by net filter by ipvs instead. Signed-off-by:

ipvs is what is actually desired so change the parameter and the modify the callers to pass struct netns_ipvs. Signed-off-by:

So store a pointer to struct netns_ipvs. Update the accesses of param->net to access param->ipvs->net instead. When lookup up struct ip_vs_conn in a hash table replace comparisons of cp->net with comparisons of cp->ipvs which is possible now that ipvs is present in ip_vs_conn_param. Signed-off-by:

The addition of sysctl_sloppy_sctp in sctp_conn_schedule resulted in a use of ipvs before it was computed. Hoist the computation of ipvs earlier to avoid this problem. Signed-off-by:

Pablo Neira Ayuso says: ==================== Netfilter/IPVS updates for net-next The following patchset contains Netfilter/IPVS updates for your net-next tree in this 4.4 development cycle, they are: 1) Schedule ICMP traffic to IPVS instances, this introduces a new schedule_icmp proc knob to enable/disable it. By default is off to retain the old behaviour. Patchset from Alex Gartrell. I'm also including what Alex originally said for the record: "The configuration of ipvs at Facebook is relatively straightforward. All ipvs instances bgp advertise a set of VIPs and the network prefers the nearest one or uses ECMP in the event of a tie. For the uninitiated, ECMP deterministically and statelessly load balances by hashing the packet (usually a 5-tuple of protocol, saddr, daddr, sport, and dport) and using that number as an index (basic hash table type logic). The problem is that ICMP packets (which contain really important information like whether or not an MTU has been exceeded) will get a different hash value and may end up at a different ipvs instance. With no information about where to route these packets, they are dropped, creating ICMP black holes and breaking Path MTU discovery. Suddenly, my mom's pictures can't load and I'm fielding midday calls that I want nothing to do with. To address this, this patch set introduces the ability to schedule icmp packets which is gated by a sysctl net.ipv4.vs.schedule_icmp. If set to 0, the old behavior is maintained -- otherwise ICMP packets are scheduled." 2) Add another proc entry to ignore tunneled packets to avoid routing loops from IPVS, also from Alex. 3) Fifteen patches from Eric Biederman to: * Stop passing nf_hook_ops as parameter to the hook and use the state hook object instead all around the netfilter code, so only the private data pointer is passed to the registered hook function. * Now that we've got state->net, propagate the netns pointer to netfilter hook clients to avoid its computation over and over again. A good example of how this has been simplified is the former TEE target (now nf_dup infrastructure) since it has killed the ugly pick_net() function. There's another round of netns updates from Eric Biederman making the line. To avoid the patchbomb again to almost all the networking mailing list (that is 84 patches) I'd suggest we send you a pull request with no patches or let me know if you prefer a better way. ==================== Signed-off-by: -
