5.2. Action on Reception of a Query When a system receives a Query, it does not respond immediately. Instead, it delays its response by a random amount of time, bounded by the Max Resp Time value derived from the Max Resp Code in the received Query message. A system may receive a variety of Queries on different interfaces and of different kinds (e.g., General Queries, Group-Specific Queries, and Group-and-Source-Specific Queries), each of which may require its own delayed response. Before scheduling a response to a Query, the system must first consider previously scheduled pending responses and in many cases schedule a combined response. Therefore, the system must be able to maintain the following state: o A timer per interface for scheduling responses to General Queries. o A per-group and interface timer for scheduling responses to Group- Specific and Group-and-Source-Specific Queries. o A per-group and interface list of sources to be reported in the response to a Group-and-Source-Specific Query. When a new Query with the Router-Alert option arrives on an interface, provided the system has state to report, a delay for a response is randomly selected in the range (0, [Max Resp Time]) where Max Resp Time is derived from Max Resp Code in the received Query message. The following rules are then used to determine if a Report needs to be scheduled and the type of Report to schedule. The rules are considered in order and only the first matching rule is applied. 1. If there is a pending response to a previous General Query scheduled sooner than the selected delay, no additional response needs to be scheduled. 2. If the received Query is a General Query, the interface timer is used to schedule a response to the General Query after the selected delay. Any previously pending response to a General Query is canceled. --8<-- Currently the timer is rearmed with new random expiration time for every incoming query regardless of possibly already pending report. Which is not aligned with the above RFE. It also might happen that higher rate of incoming queries can postpone the report after the expiration time of the first query causing group membership loss. Now the per interface general query timer is rearmed only when there is no pending report already scheduled on that interface or the newly selected expiration time is before the already pending scheduled report.

-
Johannes Berg authored
In ieee80211_xmit_fast(), 'info' is initialized to point to the skb that's passed in, but that skb may later be replaced by a clone (if it was shared), leading to an invalid pointer. This can lead to use-after-free and also later crashes since the real SKB's info->hw_queue doesn't get initialized properly. Fix this by assigning info only later, when it's needed, after the skb replacement (may have) happened. Cc: stable@vger.kernel.org Reported-by:

Guillaume Nault says: ==================== l2tp: socket lookup fixes for l2tp_ip and l2tp_ip6 There are still some cases that aren't correctly handled in the socket lookup functions of l2tp_ip and l2tp_ip6. This series fixes lookups for connected sockets and for sockets bound to the IPv6 unspecified address. bind() and connect() should now work as expected on IPPROTO_L2TP sockets. Extra features, like SO_REUSEADDR, remain unsupported. The matching conditions in __l2tp_ip6_bind_lookup() and __l2tp_ip_bind_lookup() are getting hard to read. I've kept the single test approach to make the intend of the patches clear. I'll split the conditionals once these fixes reach net-next. ==================== Signed-off-by: -

For connected sockets, __l2tp_ip{,6}_bind_lookup() needs to check the remote IP when looking for a matching socket. Otherwise a connected socket can receive traffic not originating from its peer. Drop l2tp_ip_bind_lookup() and l2tp_ip6_bind_lookup() instead of updating their prototype, as these functions aren't used. Signed-off-by:Guillaume Nault <g.nault@alphalink.fr> Signed-off-by:

An L2TP socket bound to the unspecified address should match with any address. If not, it can't receive any packet and __l2tp_ip6_bind_lookup() can't prevent another socket from binding on the same device/tunnel ID. While there, rename the 'addr' variable to 'sk_laddr' (local addr), to make following patch clearer. Signed-off-by:

->setattr() was recently implemented for socket files to sync the socket inode's uid to the new 'sk_uid' member of struct sock. It does this by copying over the ia_uid member of struct iattr. However, ia_uid is actually only valid when ATTR_UID is set in ia_valid, indicating that the uid is being changed, e.g. by chown. Other metadata operations such as chmod or utimes leave ia_uid uninitialized. Therefore, sk_uid could be set to a "garbage" value from the stack. Fix this by only copying the uid over when ATTR_UID is set. Fixes: 86741ec2 ("net: core: Add a UID field to struct sock.") Signed-off-by:

IPv4 output routes already use l3mdev device instead of loopback for dst's if it is applicable. Change local input routes to do the same. This fixes icmp responses for unreachable UDP ports which are directed to the wrong table after commit 9d1a6c4e because local_input routes use the loopback device. Moving from ingress device to loopback loses the L3 domain causing responses based on the dst to get to lost.

Jack Morgenstein authored
Demoting simple flow steering rule priority (for DPDK) was achieved by wrapping FW commands MLX4_QP_FLOW_STEERING_ATTACH/DETACH for the PF as well, and forcing the priority to MLX4_DOMAIN_NIC in the wrapper function for the PF and all VFs. In function mlx4_ib_create_flow(), this change caused the main rule creation for the PF to be wrapped, while it left the associated tunnel steering rule creation unwrapped for the PF. This mismatch caused rule deletion failures in mlx4_ib_destroy_flow() for the PF when the detach wrapper function did not find the associated tunnel-steering rule (since creation of that rule for the PF did not go through the wrapper function). Fix this by setting MLX4_QP_FLOW_STEERING_ATTACH/DETACH to be "native" (so that the PF invocation does not go through the wrapper), and perform the required priority demotion for the PF in the mlx4_ib_create_flow() code path.

mlx4_QP_FLOW_STEERING_DETACH_wrapper first removes the steering rule (which results in freeing the rule structure), and then references a field in this struct (the qp number) when releasing the busy-status on the rule's qp. Since this memory was freed, it could reallocated and changed. Therefore, the qp number in the struct may be incorrect, so that we are releasing the incorrect qp. This leaves the rule's qp in the busy state (and could possibly release an incorrect qp as well). Fix this by saving the qp number in a local variable, for use after removing the steering rule.

However, the packet should be considered as if it is being arrived via the sending interface (eth0), otherwise it would break the expectation of the userspace application (e.g. the DHCPRELEASE message from dhcp_release binary would be ignored by the dnsmasq daemon, since it come from lo which is not the interface dnsmasq bind to) Fixes: 0b922b7a ("net: original ingress device index in PKTINFO") Acked-by:

ipv6: Should use consistent conditional judgement for ip6 fragment between __ip6_append_data and ip6_finish_output There is an inconsistent conditional judgement between __ip6_append_data and ip6_finish_output functions, the variable length in __ip6_append_data just include the length of application's payload and udp6 header, don't include the length of ipv6 header, but in ip6_finish_output use (skb->len > ip6_skb_dst_mtu(skb)) as judgement, and skb->len include the length of ipv6 header. That causes some particular application's udp6 payloads whose length are between (MTU - IPv6 Header) and MTU were fragmented by ip6_fragment even though the rst->dev support UFO feature. Add the length of ipv6 header to length in __ip6_append_data to keep consistent conditional judgement as ip6_finish_output for ip6 fragment. Signed-off-by:

Under the switchdev/offloads mode, packets that don't match any e-switch steering rule are sent towards the e-switch management port. We use a NIC HW steering rule set per vport (uplink and VFs) to make them be received into the host OS through the respective vport representor netdevice. Currnetly such missed RoCE packets will not get to this NIC steering rule, and hence VF RoCE will not work over the slow path of the offloads mode. This is b/c these packets will be matched by a steering rule added by the firmware that serves RoCE traffic set on the PF NIC vport which is also the e-switch management port under SRIOV. Disabling RoCE on the e-switch management vport when we are in the offloads mode, will signal to the firmware to remove their RoCE rule, and then the missed RoCE packets will be matched by the representor NIC steering rule as any other missed packets. To achieve that, we disable RoCE on the PF vport. We do that by removing (hot-unplugging) the IB device instance associated with the PF. This is also required by our current model where the PF serves as the uplink representor and hence only SW switching (TC, bridge, OVS) applications and slow path vport mlx5e net-device should be running over that vport.

There is currently a small window during which the network device registered by stmmac can be made visible, yet all resources, including and clock and MDIO bus have not had a chance to be set up, this can lead to the following error to occur: [ 473.919358] stmmaceth 0000:01:00.0 (unnamed net_device) (uninitialized): stmmac_dvr_probe: warning: cannot get CSR clock [ 473.919382] stmmaceth 0000:01:00.0: no reset control found [ 473.919412] stmmac - user ID: 0x10, Synopsys ID: 0x42 [ 473.919429] stmmaceth 0000:01:00.0: DMA HW capability register supported [ 473.919436] stmmaceth 0000:01:00.0: RX Checksum Offload Engine supported [ 473.919443] stmmaceth 0000:01:00.0: TX Checksum insertion supported [ 473.919451] stmmaceth 0000:01:00.0 (unnamed net_device) (uninitialized): Enable RX Mitigation via HW Watchdog Timer [ 473.921395] libphy: PHY stmmac-1:00 not found [ 473.921417] stmmaceth 0000:01:00.0 eth0: Could not attach to PHY [ 473.921427] stmmaceth 0000:01:00.0 eth0: stmmac_open: Cannot attach to PHY (error: -19) [ 473.959710] libphy: stmmac: probed [ 473.959724] stmmaceth 0000:01:00.0 eth0: PHY ID 01410cc2 at 0 IRQ POLL (stmmac-1:00) active [ 473.959728] stmmaceth 0000:01:00.0 eth0: PHY ID 01410cc2 at 1 IRQ POLL (stmmac-1:01) [ 473.959731] stmmaceth 0000:01:00.0 eth0: PHY ID 01410cc2 at 2 IRQ POLL (stmmac-1:02) [ 473.959734] stmmaceth 0000:01:00.0 eth0: PHY ID 01410cc2 at 3 IRQ POLL (stmmac-1:03) Fix this by making sure that register_netdev() is the last thing being done, which guarantees that the clock and the MDIO bus are available.

Pull networking fixes from David Miller: 1) Various ipvlan fixes from Eric Dumazet and Mahesh Bandewar. The most important is to not assume the packet is RX just because the destination address matches that of the device. Such an assumption causes problems when an interface is put into loopback mode. 2) If we retry when creating a new tc entry (because we dropped the RTNL mutex in order to load a module, for example) we end up with -EAGAIN and then loop trying to replay the request. But we didn't reset some state when looping back to the top like this, and if another thread meanwhile inserted the same tc entry we were trying to, we re-link it creating an enless loop in the tc chain. Fix from Daniel Borkmann. 3) There are two different WRITE bits in the MDIO address register for the stmmac chip, depending upon the chip variant. Due to a bug we could set them both, fix from Hock Leong Kweh. 4) Fix mlx4 bug in XDP_TX handling, from Tariq Toukan. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: net: stmmac: fix incorrect bit set in gmac4 mdio addr register r8169: add support for RTL8168 series add-on card. net: xdp: remove unused bfp_warn_invalid_xdp_buffer() openvswitch: upcall: Fix vlan handling. ipv4: Namespaceify tcp_tw_reuse knob net: korina: Fix NAPI versus resources freeing net, sched: fix soft lockup in tc_classify net/mlx4_en: Fix user prio field in XDP forward tipc: don't send FIN message from connectionless socket ipvlan: fix multicast processing ipvlan: fix various issues in ipvlan_process_multicast()
