2018-03-04dsa: Pass the port to get_sset_count()Andrew Lunn
By passing the port, we allow different ports to have different statistics. This is useful since some ports have SERDES interfaces with their own statistic counters.

2018-03-04net/ipv6: Add support for path selection using hash of 5-tupleDavid Ahern
Some operators prefer IPv6 path selection to use a standard 5-tuple hash rather than just an L3 hash with the flow the label. 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.

As of commit e37b1e978bec5 ("ipv6: route: dissect flow in input path if fib rules need it") fib_multipath_hash takes an optional flow keys. If non-NULL it means the skb has already been dissected.

2018-03-01ipv6: allow userspace to add IFA_F_OPTIMISTIC addressesSabrina Dubroca
According to RFC 4429 (section 3.1), adding new IPv6 addresses as optimistic addresses is acceptable, as long as the implementation follows some rules: * Optimistic DAD SHOULD only be used when the implementation is aware that the address is based on a most likely unique interface identifier (such as in [RFC2464]), generated randomly [RFC3041], or by a well-distributed hash function [RFC3972] or assigned by Dynamic Host Configuration Protocol for IPv6 (DHCPv6) [RFC3315]. Optimistic DAD SHOULD NOT be used for manually entered addresses. Thus, it seems reasonable to allow userspace to set the optimistic flag when adding new addresses. We must not let userspace set NODAD + OPTIMISTIC, since if the kernel is not performing DAD we would never clear the optimistic flag. We must also ignore userspace's request to add OPTIMISTIC flag to addresses that have already completed DAD (addresses that don't have the TENTATIVE flag, or that have the DADFAILED flag). Then we also need to clear the OPTIMISTIC flag on permanent addresses when DAD fails. Otherwise, IFA_F_OPTIMISTIC addresses added by userspace can still be used after DAD has failed, because in ipv6_chk_addr_and_flags(), IFA_F_OPTIMISTIC overrides IFA_F_TENTATIVE. Setting IFA_F_OPTIMISTIC from userspace is conditional on CONFIG_IPV6_OPTIMISTIC_DAD and the optimistic_dad sysctl.
