      net: Fix permission check in netlink_connect() · 46833a86
      Mike Pecovnik authored
      netlink_sendmsg() was changed to prevent non-root processes from sending
      messages with dst_pid != 0.
      netlink_connect() however still only checks if nladdr->nl_groups is set.
      This patch modifies netlink_connect() to check for the same condition.

      net/cxgb4: use remove handler as shutdown handler · 687d705c
      Thadeu Lima de Souza Cascardo authored
      Without a shutdown handler, T4 cards behave very badly after a kexec.
      Some firmware calls return errors indicating allocation failures, for
      example. This is probably because thouse resources were not released by
      a BYE message to the firmware, for example.
      
      Using the remove handler guarantees we will use a well tested path.
      
      With this patch I applied, I managed to use kexec multiple times and
      probe and iSCSI login worked every time.

      ipv4: ipv6: better estimate tunnel header cut for correct ufo handling · 91a48a2e
      Hannes Frederic Sowa authored
      Currently the UFO fragmentation process does not correctly handle inner
      UDP frames.
      
      (The following tcpdumps are captured on the parent interface with ufo
      disabled while tunnel has ufo enabled, 2000 bytes payload, mtu 1280,
      both sit device):
      
      IPv6:
      16:39:10.031613 IP (tos 0x0, ttl 64, id 3208, offset 0, flags [DF], proto IPv6 (41), length 1300)
          192.168.122.151 > 1.1.1.1: IP6 (hlim 64, next-header Fragment (44) payload length: 1240) 2001::1 > 2001::8: frag (0x00000001:0|1232) 44883 > distinct: UDP, length 2000
      16:39:10.031709 IP (tos 0x0, ttl 64, id 3209, offset 0, flags [DF], proto IPv6 (41), length 844)
          192.168.122.151 > 1.1.1.1: IP6 (hlim 64, next-header Fragment (44) payload length: 784) 2001::1 > 2001::8: frag (0x00000001:0|776) 58979 > 46366: UDP, length 5471
      
      We can see that fragmentation header offset is not correctly updated.
      (fragmentation id handling is corrected by 916e4cf4 ("ipv6: reuse
      ip6_frag_id from ip6_ufo_append_data")).
      
      IPv4:
      16:39:57.737761 IP (tos 0x0, ttl 64, id 3209, offset 0, flags [DF], proto IPIP (4), length 1296)
          192.168.122.151 > 1.1.1.1: IP (tos 0x0, ttl 64, id 57034, offset 0, flags [none], proto UDP (17), length 1276)
          192.168.99.1.35961 > 192.168.99.2.distinct: UDP, length 2000
      16:39:57.738028 IP (tos 0x0, ttl 64, id 3210, offset 0, flags [DF], proto IPIP (4), length 792)
          192.168.122.151 > 1.1.1.1: IP (tos 0x0, ttl 64, id 57035, offset 0, flags [none], proto UDP (17), length 772)
          192.168.99.1.13531 > 192.168.99.2.20653: UDP, length 51109
      
      In this case fragmentation id is incremented and offset is not updated.
      
      First, I aligned inet_gso_segment and ipv6_gso_segment:
      * align naming of flags
      * ipv6_gso_segment: setting skb->encapsulation is unnecessary, as we
        always ensure that the state of this flag is left untouched when
        returning from upper gso segmenation function
      * ipv6_gso_segment: move skb_reset_inner_headers below updating the
        fragmentation header data, we don't care for updating fragmentation
        header data
      * remove currently unneeded comment indicating skb->encapsulation might
        get changed by upper gso_segment callback (gre and udp-tunnel reset
        encapsulation after segmentation on each fragment)
      
      If we encounter an IPIP or SIT gso skb we now check for the protocol ==
      IPPROTO_UDP and that we at least have already traversed another ip(6)
      protocol header.
      
      The reason why we have to special case GSO_IPIP and GSO_SIT is that
      we reset skb->encapsulation to 0 while skb_mac_gso_segment the inner
      protocol of GSO_UDP_TUNNEL or GSO_GRE packets.

      tcp: reduce the bloat caused by tcp_is_cwnd_limited() · d10473d4
      Eric Dumazet authored
      tcp_is_cwnd_limited() allows GSO/TSO enabled flows to increase
      their cwnd to allow a full size (64KB) TSO packet to be sent.
      
      Non GSO flows only allow an extra room of 3 MSS.
      
      For most flows with a BDP below 10 MSS, this results in a bloat
      of cwnd reaching 90, and an inflate of RTT.
      
      Thanks to TSO auto sizing, we can restrict the bloat to the number
      of MSS contained in a TSO packet (tp->xmit_size_goal_segs), to keep
      original intent without performance impact.
      
      Because we keep cwnd small, it helps to keep TSO packet size to their
      optimal value.
      
      Example for a 10Mbit flow, with low TCP Small queue limits (no more than
      2 skb in qdisc/device tx ring)
      
      Before patch :
      
      lpk51:~# ./ss -i dst lpk52:44862 | grep cwnd
               cubic wscale:6,6 rto:215 rtt:15.875/2.5 mss:1448 cwnd:96
      ssthresh:96
      send 70.1Mbps unacked:14 rcv_space:29200
      
      After patch :
      
      lpk51:~# ./ss -i dst lpk52:52916 | grep cwnd
               cubic wscale:6,6 rto:206 rtt:5.206/0.036 mss:1448 cwnd:15

      ipv6: reuse ip6_frag_id from ip6_ufo_append_data · 916e4cf4
      Hannes Frederic Sowa authored
      Currently we generate a new fragmentation id on UFO segmentation. It
      is pretty hairy to identify the correct net namespace and dst there.
      Especially tunnels use IFF_XMIT_DST_RELEASE and thus have no skb_dst
      available at all.
      
      This causes unreliable or very predictable ipv6 fragmentation id
      generation while segmentation.
      
      Luckily we already have pregenerated the ip6_frag_id in
      ip6_ufo_append_data and can use it here.

      net: sctp: rework multihoming retransmission path selection to rfc4960 · 4c47af4d
      Daniel Borkmann authored
      Problem statement: 1) both paths (primary path1 and alternate
      path2) are up after the association has been established i.e.,
      HB packets are normally exchanged, 2) path2 gets inactive after
      path_max_retrans * max_rto timed out (i.e. path2 is down completely),
      3) now, if a transmission times out on the only surviving/active
      path1 (any ~1sec network service impact could cause this like
      a channel bonding failover), then the retransmitted packets are
      sent over the inactive path2; this happens with partial failover
      and without it.
      
      Besides not being optimal in the above scenario, a small failure
      or timeout in the only existing path has the potential to cause
      long delays in the retransmission (depending on RTO_MAX) until
      the still active path is reselected. Further, when the T3-timeout
      occurs, we have active_patch == retrans_path, and even though the
      timeout occurred on the initial transmission of data, not a
      retransmit, we end up updating retransmit path.
      
      RFC4960, section 6.4. "Multi-Homed SCTP Endpoints" states under
      6.4.1. "Failover from an Inactive Destination Address" the
      following:
      
        Some of the transport addresses of a multi-homed SCTP endpoint
        may become inactive due to either the occurrence of certain
        error conditions (see Section 8.2) or adjustments from the
        SCTP user.
      
        When there is outbound data to send and the primary path
        becomes inactive (e.g., due to failures), or where the SCTP
        user explicitly requests to send data to an inactive
        destination transport address, before reporting an error to
        its ULP, the SCTP endpoint should try to send the data to an
        alternate __active__ destination transport address if one
        exists.
      
        When retransmitting data that timed out, if the endpoint is
        multihomed, it should consider each source-destination address
        pair in its retransmission selection policy. When retransmitting
        timed-out data, the endpoint should attempt to pick the most
        divergent source-destination pair from the original
        source-destination pair to which the packet was transmitted.
      
        Note: Rules for picking the most divergent source-destination
        pair are an implementation decision and are not specified
        within this document.
      
      So, we should first reconsider to take the current active
      retransmission transport if we cannot find an alternative
      active one. If all of that fails, we can still round robin
      through unkown, partial failover, and inactive ones in the
      hope to find something still suitable.
      
      Commit 4141ddc0 ("sctp: retran_path update bug fix") broke
      that behaviour by selecting the next inactive transport when
      no other active transport was found besides the current assoc's
      peer.retran_path. Before commit 4141ddc0, we would have
      traversed through the list until we reach our peer.retran_path
      again, and in case that is still in state SCTP_ACTIVE, we would
      take it and return. Only if that is not the case either, we
      take the next inactive transport.
      
      Besides all that, another issue is that transports in state
      SCTP_UNKNOWN could be preferred over transports in state
      SCTP_ACTIVE in case a SCTP_ACTIVE transport appears after
      SCTP_UNKNOWN in the transport list yielding a weaker transport
      state to be used in retransmission.
      
      This patch mostly reverts 4141ddc0, but also rewrites
      this function to introduce more clarity and strictness into
      the code. A strict priority of transport states is enforced
      in this patch, hence selection is active > unkown > partial
      failover > inactive.

      tipc: make bearer set up in module insertion stage · 970122fd
      Ying Xue authored
      Accidentally a side effect is involved by commit 6e967adf(tipc:
      relocate common functions from media to bearer). Now tipc stack
      handler of receiving packets from netdevices as well as netdevice
      notification handler are registered when bearer is enabled rather
      than tipc module initialization stage, but the two handlers are
      both unregistered in tipc module exit phase. If tipc module is
      inserted and then immediately removed, the following warning
      message will appear:
      
      "dev_remove_pack: ffffffffa0380940 not found"
      
      This is because in module insertion stage tipc stack packet handler
      is not registered at all, but in module exit phase dev_remove_pack()
      needs to remove it. Of course, dev_remove_pack() cannot find tipc
      protocol handler from the kernel protocol handler list so that the
      warning message is printed out.
      
      But if registering the two handlers is adjusted from enabling bearer
      phase into inserting module stage, the warning message will be
      eliminated. Due to this change, tipc_core_start_net() and
      tipc_core_stop_net() can be deleted as well.

      tipc: remove all enabled flags from all tipc components · 9fe7ed47
      Ying Xue authored
      When tipc module is inserted, many tipc components are initialized
      one by one. During the initialization period, if one of them is
      failed, tipc_core_stop() will be called to stop all components
      whatever corresponding components are created or not. To avoid to
      release uncreated ones, relevant components have to add necessary
      enabled flags indicating whether they are created or not.
      
      But in the initialization stage, if one component is unsuccessfully
      created, we will just destroy successfully created components before
      the failed component instead of all components. All enabled flags
      defined in components, in turn, become redundant. Additionally it's
      also unnecessary to identify whether table.types is NULL in
      tipc_nametbl_stop() because name stable has been definitely created
      successfully when tipc_nametbl_stop() is called.

      xen-netfront: reset skb network header before checksum · d554f73d
      Wei Liu authored
      In ed1f50c3 ("net: add skb_checksum_setup") we introduced some checksum
      functions in core driver. Subsequent change b5cf66cd ("xen-netfront:
      use new skb_checksum_setup function") made use of those functions to
      replace its own implementation.
      
      However with that change netfront is broken. It sees a lot of checksum
      error. That's because its own implementation of checksum function was a
      bit hacky (dereferencing skb->data directly) while the new function was
      implemented using ip_hdr(). The network header is not reset before skb
      is passed to the new function. When the new function tries to do its
      job, it's confused and reports error.
      
      The fix is simple, we need to reset network header before passing skb to
      checksum function. Netback is not affected as it already does the right
      thing.

      Netfilter fixes for net
      
      The following patchset contains Netfilter fixes for your net tree,
      they are:
      
      * Fix nf_trace in nftables if XT_TRACE=n, from Florian Westphal.
      
      * Don't use the fast payload operation in nf_tables if the length is
        not power of 2 or it is not aligned, from Nikolay Aleksandrov.
      
      * Fix missing break statement the inet flavour of nft_reject, which
        results in evaluating IPv4 packets with the IPv6 evaluation routine,
        from Patrick McHardy.
      
      * Fix wrong kconfig symbol in nft_meta to match the routing realm,
        from Paul Bolle.
      
      * Allocate the NAT null binding when creating new conntracks via
        ctnetlink to avoid that several packets race at initializing the
        the conntrack NAT extension, original patch from Florian Westphal,
        revisited version from me.
      
      * Fix DNAT handling in the snmp NAT helper, the same handling was being
        done for SNAT and DNAT and 2.4 already contains that fix, from
        Francois-Xavier Le Bail.

        One fix touches code outside of arch/arm, which is related to sorting

        conversion from PFNs to addresses where people assume that shifting an
        unsigned long left by PAGE_SHIFT results in a correct address.  This
        is not the case with C: the integer promotion happens at assignment
        after evaluation.  This fixes the recently introduced dma_max_pfn()

      of_mdio: fix phy interrupt passing · f15c586d
      Ben Dooks authored
      The of_mdiobus_register_phy() is not setting phy->irq thus causing
      some drivers to incorrectly assume that the PHY does not have an
      IRQ associated with it. Not only do some drivers report no IRQ
      they do not install an interrupt handler for the PHY.
      
      Simplify the code setting irq and set the phy->irq at the same
      time so that we cover the following issues, which should cover
      all the cases the code will find:
      
      - Set phy->irq if node has irq property and mdio->irq is NULL
      - Set phy->irq if node has no irq and mdio->irq is not NULL
      - Leave phy->irq as PHY_POLL default if none of the above
      
      This fixes the issue:
       net eth0: attached PHY 1 (IRQ -1) to driver Micrel KSZ8041RNLI
      
      to the correct:
       net eth0: attached PHY 1 (IRQ 416) to driver Micrel KSZ8041RNLI

      net: ethernet: update dependency and help text of mvneta · 4b636b53
      Thomas Petazzoni authored
      With the introduction of the support for Armada 375 and Armada 38x,
      the hidden Kconfig option MACH_ARMADA_370_XP is being renamed to
      MACH_MVEBU_V7. Therefore, the dependency that was used for the mvneta
      driver can no longer work. This commit replaces this dependency by a
      dependency on PLAT_ORION, which is used similarly for the mv643xx_eth
      driver.
      
      In addition to this, it takes this opportunity to adjust the
      description and help text to indicate that the driver can is also used
      for Armada 38x. Note that Armada 375 cannot use this driver as it has
      a completely different networking unit, which will require a separate
      driver.
