      strp: Stream parser for messages
      
      This patch set introduces a utility for parsing application layer
      protocol messages in a TCP stream. This is a generalization of the
      mechanism implemented of Kernel Connection Multiplexor.
      
      This patch set adapts KCM to use the strparser. We expect that kTLS
      can use this mechanism also. RDS would probably be another candidate
      to use a common stream parsing mechanism.
      
      The API includes a context structure, a set of callbacks, utility
      functions, and a data ready function. The callbacks include
      a parse_msg function that is called to perform parsing (e.g.
      BPF parsing in case of KCM), and a rcv_msg function that is called
      when a full message has been completed.
      
      For strparser we specify the return codes from the parser to allow
      the backend to indicate that control of the socket should be
      transferred back to userspace to handle some exceptions in the
      stream: The return values are:
      
            >0 : indicates length of successfully parsed message
             0  : indicates more data must be received to parse the message
             -ESTRPIPE : current message should not be processed by the
                kernel, return control of the socket to userspace which
                can proceed to read the messages itself
             other < 0 : Error is parsing, give control back to userspace
                assuming that synchronization is lost and the stream
                is unrecoverable (application expected to close TCP socket)
      
      There is one issue I haven't been able to fully resolve. If parse_msg
      returns ESTRPIPE (wants control back to userspace) the parser may
      already have consumed some bytes of the message. There is no way to
      put bytes back into the TCP receive queue and tcp_read_sock does not
      allow an easy way to peek messages. In lieu of a better solution, we
      return ENODATA on the socket to indicate that the data stream is
      unrecoverable (application needs to close socket). This condition
      should only happen if an application layer message header is split
      across two skbuffs and parsing just the first skbuff wasn't sufficient
      to determine the that transfer to userspace is needed.
      
      This patch set contains:
      
        - strparser implementation
        - changes to kcm to use strparser
        - strparser.txt documentation
      
      v2:
        - Add copyright notice to C files
        - Remove GPL module license from strparser.c
        - Add report of rxpause
      
      v3:
        - Restore GPL module license
        - Use EXPORT_SYMBOL_GPL
      
      v4:
        - Removed unused function, changed another to be static as suggested
          by davem
        - Rewoked data_ready to be called from upper layer, no longer requires
          taking over socket data_ready callback as suggested by Lance Chao
      
      Tested:
        - Ran a KCM thrash test for 24 hours. No behavioral or performance
          differences observed.

      strparser: Stream parser for messages · 43a0c675
      Tom Herbert authored
      This patch introduces a utility for parsing application layer protocol
      messages in a TCP stream. This is a generalization of the mechanism
      implemented of Kernel Connection Multiplexor.
      
      The API includes a context structure, a set of callbacks, utility
      functions, and a data ready function.
      
      A stream parser instance is defined by a strparse structure that
      is bound to a TCP socket. The function to initialize the structure
      is:
      
      int strp_init(struct strparser *strp, struct sock *csk,
                    struct strp_callbacks *cb);
      
      csk is the TCP socket being bound to and cb are the parser callbacks.
      
      The upper layer calls strp_tcp_data_ready when data is ready on the lower
      socket for strparser to process. This should be called from a data_ready
      callback that is set on the socket:
      
      void strp_tcp_data_ready(struct strparser *strp);
      
      A parser is bound to a TCP socket by setting data_ready function to
      strp_tcp_data_ready so that all receive indications on the socket
      go through the parser. This is assumes that sk_user_data is set to
      the strparser structure.
      
      There are four callbacks.
       - parse_msg is called to parse the message (returns length or error).
       - rcv_msg is called when a complete message has been received
       - read_sock_done is called when data_ready function exits
       - abort_parser is called to abort the parser
      
      The input to parse_msg is an skbuff which contains next message under
      construction. The backend processing of parse_msg will parse the
      application layer protocol headers to determine the length of
      the message in the stream. The possible return values are:
      
         >0 : indicates length of successfully parsed message
         0  : indicates more data must be received to parse the message
         -ESTRPIPE : current message should not be processed by the
            kernel, return control of the socket to userspace which
            can proceed to read the messages itself
         other < 0 : Error is parsing, give control back to userspace
            assuming that synchronzation is lost and the stream
            is unrecoverable (application expected to close TCP socket)
      
      In the case of error return (< 0) strparse will stop the parser
      and report and error to userspace. The application must deal
      with the error. To handle the error the strparser is unbound
      from the TCP socket. If the error indicates that the stream
      TCP socket is at recoverable point (ESTRPIPE) then the application
      can read the TCP socket to process the stream. Once the application
      has dealt with the exceptions in the stream, it may again bind the
      socket to a strparser to continue data operations.
      
      Note that ENODATA may be returned to the application. In this case
      parse_msg returned -ESTRPIPE, however strparser was unable to maintain
      synchronization of the stream (i.e. some of the message in question
      was already read by the parser).
      
      strp_pause and strp_unpause are used to provide flow control. For
      instance, if rcv_msg is called but the upper layer can't immediately
      consume the message it can hold the message and pause strparser.

      While commit 9c706a49 ("net: ipconfig: fix use after free") avoids
      the use after free, the resulting code still ends up calling both the
      ic_setup_if() and ic_setup_routes() after calling ic_close_devs(), and
      access to the device is still required.
      
      Move the call to ic_close_devs() to the very end of the function.

      net_sched: convert tcf_exts from list to pointer array · 22dc13c8
      WANG Cong authored
      As pointed out by Jamal, an action could be shared by
      multiple filters, so we can't use list to chain them
      any more after we get rid of the original tc_action.
      Instead, we could just save pointers to these actions
      in tcf_exts, since they are refcount'ed, so convert
      the list to an array of pointers.
      
      The "ugly" part is the action API still accepts list
      as a parameter, I just introduce a helper function to
      convert the array of pointers to a list, instead of
      relying on the C99 feature to iterate the array.

      pull request for net-next: batman-adv 2016-08-16
      
      This feature patchset is all about adding netlink support, which should
      supersede our debugfs configuration interface in the long run. It is
      especially necessary when batman-adv should be used in different
      namespaces, since debugfs can not differentiate between those.
      
      More specifically, the following changes are included:
      
       - Two fixes for namespace handling by Andrew Lunn, checking also the
         namespaces for parent interfaces, and supress debugfs entries
         for non-default netns
      
       - Implement various netlink commands for the new interface, by
         Matthias Schiffer, Andrew Lunn, Sven Eckelmann and Simon Wunderlich
         (13 patches):
          * routing algorithm list
          * hardif list
          * translation tables (local and global)
          * TTVN for the translation tables
          * originator and neighbor tables for B.A.T.M.A.N. IV
            and B.A.T.M.A.N. V
          * gateway dump functionality for B.A.T.M.A.N. IV
            and B.A.T.M.A.N. V
          * Bridge Loop Avoidance claims, and corresponding BLA group
          * Bridge Loop Avoidance backbone tables
      
       - Finally, mark batman-adv as netns compatible, by Andrew Lunn (1 patch)

      Intel Wired LAN Driver Updates 2016-08-16
      
      This series contains fixes to e1000e, igb, ixgbe and i40e.
      
      Kshitiz Gupta provides a fix for igb to resolve the PHY delay compensation
      math in several functions.
      
      Jarod Wilson provides a fix for e1000e which had to broken up into 2
      patches, first is prepares the driver for expanding the list of NICs
      that have occasional ~10 hour clock jumps when being used for PTP.
      Second patch actually fixes i218 silicon which has been experiencing
      the clock jumps while using PTP.
      
      Alex provides 2 patches for ixgbe now that he is back at Intel.  First
      fixes setting VLNCTRL.VFE bit, which was left unchanged in earlier patches
      which resulted in disabling VLAN filtering for all the VFs.  Second
      corrects the support for disabling the VLAN tag filtering via the
      feature bit.
      
      Lastly, David fixes i40e which was causing a kernel panic when
      non-contiguous traffic classes or traffic classes not starting with TC0,
      were configured on a link partner switch.  To fix this, changed the
      logic when determining the total number of TCs enabled.

      ====================
      mlxsw: IPv4 UC router fixes
      
      Ido says:
      Patches 1-3 fix a long standing problem in the driver's init sequence,
      which manifests itself quite often when routing daemons try to configure
      an IP address on registered netdevs that don't yet have an associated
      vPort.
      
      Patches 4-9 add missing packet traps for the router to work properly and
      also fix ordering issue following the recent changes to the driver's init
      sequence.
      
      The last patch isn't related to the router, but fixes a general problem
      in which under certain conditions packets aren't trapped to CPU.
      
      v1->v2:
      - Change order of patch 7
      - Add patch 6 following Ilan's comment
      - Add patchset name and cover letter

      mlxsw: spectrum: Allow packets to be trapped from any PG · 9ffcc372
      Ido Schimmel authored
      When packets enter the device they are classified to a priority group
      (PG) buffer based on their PCP value. After their egress port and
      traffic class are determined they are moved to the switch's shared
      buffer and await transmission, if:
      
      (Ingress{Port}.Usage < Thres && Ingress{Port,PG}.Usage < Thres &&
       Egress{Port}.Usage < Thres && Egress{Port,TC}.Usage < Thres)
      ||
      (Ingress{Port}.Usage < Min || Ingress{Port,PG} < Min ||
       Egress{Port}.Usage < Min || Egress{Port,TC}.Usage < Min)
      
      Packets scheduled to transmission through CPU port (trapped to CPU) use
      traffic class 7, which has a zero maximum and minimum quotas. However,
      when such packets arrive from PG 0 they are admitted to the shared
      buffer as PG 0 has a non-zero minimum quota.
      
      Allow all packets to be trapped to the CPU - regardless of the PG they
      were classified to - by assigning a 10KB minimum quota for CPU port and
      TC7.

      Before destroying the 802.1Q FID we should first remove the VID-to-FID

      mlxsw: spectrum: Add missing rollbacks in error path · 0583272d
      Ido Schimmel authored
      While going over the code I noticed we are missing two rollbacks in the
      port's creation error path. Add them and adjust the place of one of them
      in the port's removal sequence so that both are symmetric.

      mlxsw: spectrum: Trap loop-backed packets · a94a614f
      Ido Schimmel authored
      One of the conditions to generate an ICMP Redirect Message is that "the
      packet is being forwarded out the same physical interface that it was
      received from" (RFC 1812).
      
      Therefore, we need to be able to trap such packets and let the kernel
      decide what to do with them.
      
      For each RIF, enable the loop-back filter, which will raise the LBERROR
      trap whenever the ingress RIF equals the egress RIF.

      Add the following traps:
      
      1) MTU Error: Trap packets whose size is bigger than the egress RIF's
      MTU. If DF bit isn't set, traffic will continue to be routed in slow
      path.
      
      2) TTL Error: Trap packets whose TTL expired. This allows traceroute to
      work properly.

      mlxsw: spectrum: Mark port as active before registering it · 2f25844c
      Ido Schimmel authored
      Commit bbf2a475 ("mlxsw: spectrum: Initialize ports at the end of
      init sequence") moved ports initialization to the end of the init
      sequence, which means ports are the first to be removed during fini.
      
      Since the FDB delayed work is still active when ports are removed it's
      possible for it to process FDB notifications of inactive ports,
      resulting in a warning message.
      
      Fix that by marking ports as inactive only after unregistering them. The
      NETDEV_UNREGISTER event will invoke bridge's driver port removal
      sequence that will cause the FDB (and FDB notifications) to be flushed.

      mlxsw: spectrum: Create PVID vPort before registering netdevice · 05978481
      Ido Schimmel authored
      After registering a netdevice it's possible for user space applications
      to configure an IP address on it. From the driver's perspective, this
      means a router interface (RIF) should be created for the PVID vPort.
      
      Therefore, we must create the PVID vPort before registering the
      netdevice.

      mlxsw: spectrum: Remove redundant errors from the code · fa66d7e3
      Ido Schimmel authored
      Currently, when device configuration fails we emit errors to the kernel
      log despite the fact we already get these from the EMAD transaction
      layer, so remove them.
      
      In addition to being unnecessary, removing these error messages will
      allow us to reuse mlxsw_sp_port_add_vid() to create the PVID vPort
      before registering the netdevice.

      mlxsw: spectrum: Don't return upon error in removal path · 7a35583e
      Ido Schimmel authored
      When removing a VLAN filter from the device we shouldn't return upon the
      first error we encounter, as otherwise we'll have resources that will
      never be freed nor used.
      
      Instead, we should keep trying to free as much resources as possible in
      a best effort mode.
      
      Remove the error message as well, since we already get these from the
      EMAD transaction code.
