__inet6_lookup_established() expect th->dport passed in host-endian, not net-endian. The reason is microoptimization in __inet6_lookup(), but if you use the lower-level helpers, you have to play by their rules... Signed-off-by:

Ido Schimmel says: ==================== mlxsw: Enable MC-aware mode for mlxsw ports Petr says: Due to an issue in Spectrum chips, when unicast traffic shares the same queue as BUM traffic, and there is a congestion, the BUM traffic is admitted to the queue anyway, thus pushing out all UC traffic. In order to give unicast traffic precedence over BUM traffic, configure multicast-aware mode on all ports. Under multicast-aware regime, when assigning traffic class to a packet, the switch doesn't merely take the value prescribed by the QTCT register. For BUM traffic, it instead assigns that value plus 8. That limits the number of available TCs, but since mlxsw currently only uses the lower eight anyway, it is no real loss. The two TCs (UC and MC one) are then mapped to the same subgroup and strictly prioritized so that UC traffic is preferred in case of congestion. In patch #1, introduce a new register, QTCTM, which enables the multicast-aware mode. In patch #2, fix a typo in related code. In patch #3, set up TCs and QTCTM to enable multicast-aware mode. ==================== Signed-off-by: -

In order to give unicast traffic precedence over BUM traffic, configure multicast-aware mode on all ports. Under multicast-aware regime, when assigning traffic class to a packet, the switch doesn't merely take the value prescribed by the QTCT register. For BUM traffic, it instead assigns that value plus 8. ETS elements for TCs 8..15 thus need to be configured as well. Extend mlxsw_sp_port_ets_init() so that it maps each of them to the same subgroup as their corresponding TC from the range 0..7, such that TCs X and X+8 map to the same subgroup. The existing code configures TCs with strict priority. So far this was immaterial, because each TC had its own subgroup. Now that two TCs share a subgroup it becomes important. TCs are prioritized in order of 7, 6, ..., 0, 15, 14, ..., 8: the higher TCs used for BUM traffic end up being deprioritized. Since that's what's needed, keep that configuration as it is, and configure the new TCs likewise. Finally in mlxsw_sp_port_create(), invoke configuration of QTCTM to enable MC-aware mode on each port. Signed-off-by:

don't bother with pathological cases, they only waste cycles. IPv6 requires a minimum MTU of 1280 so we should never see fragments smaller than this (except last frag). v3: don't use awkward "-offset + len" v2: drop IPv4 part, which added same check w. IPV4_MIN_MTU (68). There were concerns that there could be even smaller frags generated by intermediate nodes, e.g. on radio networks.

Peter Oskolkov says: ==================== ip: Use rb trees for IP frag queue. This patchset * changes IPv4 defrag behavior to match that of IPv6: overlapping fragments now cause the whole IP datagram to be discarded (suggested by David Miller): there are no legitimate use cases for overlapping fragments; * changes IPv4 defrag queue from a list to a rb tree (suggested by Eric Dumazet): this change removes a potential attach vector. Upcoming patches will contain similar changes for IPv6 frag queue, as well as a comprehensive IP defrag self-test (temporarily delayed). ==================== Signed-off-by: -

When a ICMPV6_PKT_TOOBIG is received from a link local address the pmtu will be updated on a route with an arbitrary interface index. Subsequent packets sent back to the same link local address may therefore end up not considering the updated pmtu. Current behavior breaks TAHI v6LC4.1.4 Reduce PMTU On-link. Referring to RFC 1981: Section 3: "Note that Path MTU Discovery must be performed even in cases where a node "thinks" a destination is attached to the same link as itself. In a situation such as when a neighboring router acts as proxy [ND] for some destination, the destination can to appear to be directly connected but is in fact more than one hop away."

This patch is to support automatic configuration for ptp timer. If required ptp dts properties are not provided, driver could try to calculate a set of default configurations to initialize the ptp timer. This makes the driver work for many boards which don't have the required ptp dts properties in current kernel. Also the users could set dts properties by themselves according to their requirement.

Michael Chan says: ==================== bnxt_en: Updates for net-next. This series includes the usual firmware spec update. The driver has added external phy loopback test and phy setup retry logic that is needed during hotplug. In the SRIOV space, the driver has added a new VF resource allocation mode that requires the VF driver to reserve resources during IFUP. IF state changes are now propagated to firmware so that firmware can release some resources during IFDOWN. ethtool method to get firmware core dump and hwmon temperature reading have been added. DSCP to user priority support has been added to the driver's DCBNL interface, and the CoS queue logic has been refined to make sure that the special RDMA Congestion Notification hardware CoS queue will not be used for networking traffic. ==================== Signed-off-by: -

The CNP CoS queue is reserved for internal RDMA Congestion Notification Packets (CNP) and should not be used for a TC. Modify the CoS queue discovery code to skip over the CNP CoS queue and to reduce bp->max_tc accordingly. However, if RDMA is disabled in NVRAM, the the CNP CoS queue can be used for a TC.

Set the default hash mode flag in HWRM_VNIC_RSS_CFG to signal to the firmware that the driver is compliant with the latest spec. With that, the firmware can return expanded RSS profile IDs that the driver checks to setup the proper gso_type for GRO-HW packets. But instead of checking for the new profile IDs, we check the IP_TYPE flag in TPA_START which is more straight forward than checking a list of profile IDs. Signed-off-by:

The driver gathers statistics using 2 mechanisms. Some stats are DMA'ed directly from hardware and others are polled from the driver's timer.

Pablo Neira Ayuso says: ==================== Netfilter updates for net-next The following patchset contains Netfilter updates for your net-next tree: 1) Support for transparent proxying for nf_tables, from Mate Eckl. 2) Patchset to add OS passive fingerprint recognition for nf_tables, from Fernando Fernandez. This takes common code from xt_osf and place it into the new nfnetlink_osf module for codebase sharing. 3) Lightweight tunneling support for nf_tables. 4) meta and lookup are likely going to be used in rulesets, make them direct calls. From Florian Westphal. A bunch of incremental updates: 5) use PTR_ERR_OR_ZERO() from nft_numgen, from YueHaibing. 6) Use kvmalloc_array() to allocate hashtables, from Li RongQing. 7) Explicit dependencies between nfnetlink_cttimeout and conntrack timeout extensions, from Harsha Sharma. 8) Simplify NLM_F_CREATE handling in nf_tables. 9) Removed unused variable in the get element command, from YueHaibing. 10) Expose bridge hook priorities through uapi, from Mate Eckl. And a few fixes for previous Netfilter batch for net-next: 11) Use per-netns mutex from flowtable event, from Florian Westphal. 12) Remove explicit dependency on iptables CT target from conntrack zones, from Florian. 13) Fix use-after-free in rmmod nf_conntrack path, also from Florian. ==================== Signed-off-by: -
