Among several other changes it contains the rest of the fixes & cleanups from the Bluetooth UnplugFest (that didn't need to be hurried to 4.3). - Refactoring & cleanups to 6lowpan code - New USB ids for two Atheros controllers and BCM43142A0 from Broadcom - Fix (quirk) for broken Broadcom BCM2045 controllers - Support for latest Apple controllers - Improvements to the vendor diagnostic message support Please let me know if there are any issues pulling. Thanks. ==================== Signed-off-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-10-23 This series contains updates to i40e, i40evf, if_link, ixgbe and ixgbevf. Anjali adds a workaround to drop any flow control frames from being transmitted from any VSI, so that a malicious VF cannot send flow control or PFC packets out on the wire. Also fixed a bug in debugfs by grabbing the filter list lock before adding or deleting a filter. Akeem fixes an issue where we were unconditionally returning VEB bridge mode before allowing LB in the add VSI routine, resolve by checking if the bridge is actually in VEB mode first. Mitch fixed an issue where the incorrect structure was being used for VLAN filter list, which meant the VLAN filter list did not get processed correctly and VLAN filters would not be re-enabled after any kind of reset. Helin fixed a problem of possibly getting inconsistent flow control status after a PF reset. The issue was requested_mode was being set with a default value during probe, but the hardware state could be a different value from this mode. Carolyn fixed a problem where the driver output of the OEM version string varied from the other tools. Jean Sacren fixes up kernel documentation by fixing function header comments to match actual variables used in the functions. Also cleaned up variable initialization, when the variable would be over-written immediately. Hiroshi Shimanoto provides three patches to add "trusted" VF by adding netlink directives and an NDO entry. Then implement these new controls in ixgbe and ixgbevf. This series has gone through several iterations to address all the suggested community changes and concerns. ==================== Signed-off-by: -

Change the selection of a multipath route to use a flow-based hash. This more suitable for traffic sensitive to reordering within a flow (e.g. TCP, L2VPN) and whilst still allowing a good distribution of traffic given enough flows. Selection of the path for a multipath route is done using a hash of: 1. Label stack up to MAX_MP_SELECT_LABELS labels or up to and including entropy label, whichever is first. 2. 3-tuple of (L3 src, L3 dst, proto) from IPv4/IPv6 header in MPLS payload, if present. Naturally, a 5-tuple hash using L4 information in addition would be possible and be better in some scenarios, but there is a tradeoff between looking deeper into the packet to achieve good distribution, and packet forwarding performance, and I have erred on the side of the latter as the default.

This patch adds support for MPLS multipath routes. Includes following changes to support multipath: - splits struct mpls_route into 'struct mpls_route + struct mpls_nh' - 'struct mpls_nh' represents a mpls nexthop label forwarding entry - moves mpls route and nexthop structures into internal.h - A mpls_route can point to multiple mpls_nh structs - the nexthops are maintained as a array (similar to ipv4 fib) - In the process of restructuring, this patch also consistently changes all labels to u8 - Adds support to parse/fill RTA_MULTIPATH netlink attribute for multipath routes similar to ipv4/v6 fib - In this patch, the multipath route nexthop selection algorithm simply returns the first nexthop. It is replaced by a hash based algorithm from Robert Shearman in the next patch - mpls_route_update cleanup: remove 'dev' handling in mpls_route_update. mpls_route_update though implemented to update based on dev, it was never used that way. And the dev handling gets tricky with multiple nexthops. Cannot match against any single nexthops dev. So, this patch removes the unused 'dev' handling in mpls_route_update. - dead route/path handling will be implemented in a subsequent patch Example: $ip -f mpls route add 100 nexthop as 200 via inet 10.1.1.2 dev swp1 \ nexthop as 700 via inet 10.1.1.6 dev swp2 \ nexthop as 800 via inet 40.1.1.2 dev swp3 $ip -f mpls route show 100 nexthop as to 200 via inet 10.1.1.2 dev swp1 nexthop as to 700 via inet 10.1.1.6 dev swp2 nexthop as to 800 via inet 40.1.1.2 dev swp3 Signed-off-by: -

Neil Armstrong says: ==================== Refactor nested mdiobus read/write functions In order to avoid locked signal false positive for nested mdiobus read/write calls, nested code was introduced in mv88e6xxx and mdio-mux. But mv88e6060 also needs such nested mdiobus read/write calls. For sake of refactoring, introduce nested variants of mdiobus read/write and make them used by mv88e6xxx and mv88e6060. In a next patch, mdio-mux should also use these variant calls. ==================== Signed-off-by: -

The limitation of the number of multicast address for VF is not enough for the large scale server with SR-IOV feature. IPv6 requires the multicast MAC address for each IP address to handle the Neighbor Solicitation message. We couldn't assign over 30 IPv6 addresses to a single VF. This patch introduces the new mailbox API, IXGBE_VF_UPDATE_XCAST_MODE, to update multicast mode of VF. This adds 3 modes; - NONE only L2 exact match addresses or Flow Director enabled - MULTI BAM and ROMPE set - ALLMULTI BAM, ROMPE and MPE set If a guest VF user wants over 30 MAC multicast addresses, set IFF_ALLMULTI to request PF to update xcast mode to enable VF multicast promiscuous mode. On the other hand, enabling VF multicast promiscuous mode may affect security and performance in the network of the NIC. Only trusted VF can enable multicast promiscuous mode. The behavior of untrusted VF is the same as previous version. Signed-off-by:

Implements the new netdev op to trust VF in ixgbe. The administrator can turn on and off VF trusted by ip command which supports trust message. # ip link set dev eth0 vf 1 trust on or # ip link set dev eth0 vf 1 trust off Send a ping to reset VF on changing the status of trusting.

Multiple cpus can process duplicates of incoming ACK messages matching a SYN_RECV request socket. This is a rare event under normal operations, but definitely can happen. Only one must win the race, otherwise corruption would occur. To fix this without adding new atomic ops, we use logic in inet_ehash_nolisten() to detect the request was present in the same ehash bucket where we try to insert the new child. If request socket was not found, we have to undo the child creation. This actually removes a spin_lock()/spin_unlock() pair in reqsk_queue_unlink() for the fast path.

Currently adding a new ipv4 address always cause the creation of the related network route, with default metric. When a host has multiple interfaces on the same network, multiple routes with the same metric are created. If the userspace wants to set specific metric on each routes, i.e. giving better metric to ethernet links in respect to Wi-Fi ones, the network routes must be deleted and recreated, which is error-prone. This patch implements the support for IFA_F_NOPREFIXROUTE for ipv4 address. When an address is added with such flag set, no associated network route is created, no network route is deleted when said IP is gone and it's up to the user space manage such route. Signed-off-by:

Vivien Didelot says: ==================== net: dsa: implement port_fdb_dump in drivers Not all switch chips provide a Get Next kind of operation to dump FDB entries. It is preferred to let the driver handle the dump operation the way it works best for the chip. Thus, drop port_fdb_getnext and implement the port_fdb_dump operation in DSA, which pushes the switchdev FDB dump callback down to the drivers. mv88e6xxx is the only driver affected and is updated accordingly. v3 -> v4: fix rejects on latest net-next v2 -> v3: opencode switchdev_obj_dump_cb_t to avoid multiple typedef; use ether_addr_copy in fdb_dump v1 -> v2: fix a few "return err" instead of "goto unlock" in mv88e6xxx.c ==================== Signed-off-by: -
