2018-03-05net: Convert arp_tables_net_ops and ip6_tables_net_opsKirill Tkhai
These pernet_operations call xt_proto_init() and xt_proto_fini(), which just register and unregister /proc entries. They are safe to be marked as async. Signed-off-by: Kirill Tkhai <ktkhai@virtuozzo.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-03-05net: Convert log pernet_operationsKirill Tkhai
These pernet_operations use nf_log_set() and nf_log_unset() in their methods: nf_log_bridge_net_ops nf_log_arp_net_ops nf_log_ipv4_net_ops nf_log_ipv6_net_ops nf_log_netdev_net_ops Nobody can send such a packet to a net before it's became registered, nobody can send a packet after all netdevices are unregistered. So, these pernet_operations are able to be marked as async. Signed-off-by: Kirill Tkhai <ktkhai@virtuozzo.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-03-05net: Convert broute_net_ops, frame_filter_net_ops and frame_nat_net_opsKirill Tkhai
These pernet_operations use ebt_register_table() and ebt_unregister_table() to act on the tables, which are used as argument in ebt_do_table(), called from ebtables hooks. Since there are no net-related bridge packets in-flight, when the init and exit methods are called, these pernet_operations are safe to be executed in parallel with any other.

2018-03-05net: Make RX-FCS and LRO mutually exclusiveGal Pressman
LRO and RX-FCS offloads cannot be enabled at the same time since it is not clear what should happen to the FCS of each coalesced packet. The FCS is not really part of the TCP payload, hence cannot be merged into one big packet. On the other hand, providing one big LRO packet with one FCS contradicts the RX-FCS feature goal. Use the fix features mechanism in order to prevent intersection of the features and drop LRO in case RX-FCS is requested.

In addition, some network operators prefer IPv6 path selection to use the 5-tuple. To that end, add support to IPv6 for multipath hash policy similar to bf4e0a3db97eb ("net: ipv4: add support for ECMP hash policy choice"). The default is still L3 which covers source and destination addresses along with flow label and IPv6 protocol. This gives users a choice in hash algorithms if they believe L3 only and the IPv6 flow label are not sufficient for their use case. A separate sysctl is added for IPv6, allowing IPv4 and IPv6 to use different algorithms if desired. The first 3 patches modify the IPv4 variant so that at the end of the patch set the ipv4 and ipv6 implementations are direct parallels. Patch 4 refactors the existing rt6_multipath_hash in preparation for adding the policy option. Patch 5 renames the existing netevent to have IPv4 in the name so ipv4 changes can be distinguished from IPv6 if the netevent handler cares. Patch 6 adds the skb as an argument through the FIB lookup functions to the multipath selection. Needed for the forwarding case. Patch 7 adds the L4 hash support. Patch 8 adds the hook for the netevent to the spectrum driver to update the ASIC. Patch 9 removes no longer used code. Patch 10 adds a testcase for IPv6 multipath with L4 hash. v3 - comments from Ido: - removed fib_info arg in patch 1; left by mistake on rebase to net-next - removed __get_hash_from_flowi4 declaration - line wrap change to spectrum_router.c to maintain 80 chars v2 - rebased to top of tree - added refactor of fib_multipath_hash following recent change - plumb skb through lookup functions to multipath selection - fix sysctl setting; was missing the data set in ipv6_sysctl_net_init - added test case RFC to v1: - rebase to top of net-next - fix addr_type in hash_keys and removed flow label as noticed by Ido - added a comment to cover letter about choice in algorithms based on use case per Or's comments ==================== Signed-off-by: David S.
