      ieee802154: properly unshare skbs in ieee802154 *_rcv functions · 8cfad496
      Phoebe Buckheister authored 
      ieee802154 sockets do not properly unshare received skbs, which leads to
panics (at least) when they are used in conjunction with 6lowpan, so
run skb_share_check on received skbs.
6lowpan also contains a use-after-free, which is trivially fixed by
replacing the inlined skb_share_check with the explicit call.

====================
this is a pull request of three patches for net-next/master.

It consists of a patch by Oliver Hartkopp, which unifies the MTU
settings for CAN interfaces. A patch by Christopher R. Baker populates
netdev::dev_id for udev discrimination for multi interface CAN devices.
Alexander Shiyan contributes a patch for the mcp251x driver which fixes
the regulators operation if CONFIG_REGULATOR is not enabled.

      doc: update driver TX algorithm in timestamping.txt · 59cb89e6
      Jakub Kicinski authored 
      Since cd4d8fda ("net: kernel panic in dev_hard_start_xmit:
remove faulty software TX time stamping") dev_hard_start_xmit()
will not provide software timestamps. It's a responsibility of
the drivers to call skb_tx_timestamp() at the right time.

      net: sched: use no more than one page in struct fw_head · d37d8ac1
      Eric Dumazet authored 
      In commit b4e9b520 ("[NET_SCHED]: Add mask support to fwmark
classifier") Patrick added an u32 field in fw_head, making it slightly
bigger than one page.

Lets use 256 slots to make fw_hash() more straight forward, and move
@mask to the beginning of the structure as we often use a small number
of skb->mark. @mask and first hash buckets share the same cache line.

This brings back the memory usage to less than 4000 bytes, and permits
John to add a rcu_head at the end of the structure later without any
worry.

      Steffen Klassert says:

====================
One patch to rename a newly introduced struct. The rest is
the rework of the IPsec virtual tunnel interface for ipv6 to
support inter address family tunneling and namespace crossing.

1) Rename the newly introduced struct xfrm_filter to avoid a
   conflict with iproute2. From Nicolas Dichtel.

2) Introduce xfrm_input_afinfo to access the address family
   dependent tunnel callback functions properly.

3) Add and use a IPsec protocol multiplexer for ipv6.

4) Remove dst_entry caching. vti can lookup multiple different
   dst entries, dependent of the configured xfrm states. Therefore
   it does not make to cache a dst_entry.

5) Remove caching of flow informations. vti6 does not use the the
   tunnel endpoint addresses to do route and xfrm lookups.

6) Update the vti6 to use its own receive hook.

7) Remove the now unused xfrm_tunnel_notifier. This was used from vti
   and is replaced by the IPsec protocol multiplexer hooks.

8) Support inter address family tunneling for vti6.

9) Check if the tunnel endpoints of the xfrm state and the vti interface
   are matching and return an error otherwise.

10) Enable namespace crossing for vti devices.

      i40evf: Rename i40e_ptype_lookup i40evf_ptype_lookup · 37a622c1
      Eric W Biederman authored 
      When compiling the i40e and the i40evf driver into the same kernel I get:
LD      drivers/net/ethernet/intel/built-in.o
drivers/net/ethernet/intel/i40evf/built-in.o:(.data+0x300): multiple definition of `i40e_ptype_lookup'

make[2]: *** [drivers/net/ethernet/intel] Error 2

Fix this by renaming the i40evf version of this structure from

====================
Altera Triple Speed Ethernet (TSE) Driver

This is the version 6 submission for the Altera Triple Speed Ethernet (TSE)
driver. All comments received during the version 2, 3, 4, and 5 submissions
have been accepted. Please find the change log and a description of the
submission below.

If you find the submission acceptable, please consider this patch set for
inclusion into the Linux kernel.

V6: Address comments from V5 review
    - add call to skb_tx_timestamp in the drivers transmit path
    - correct use of unsigned int where it was cast to pointer. Use types
      appropriate for intended and correct use to let the compiler warn us
      when type usage is incorrect.
    - use correct semantics for pointer arithmetic in same code path

V5: Address comments from V4 review
    - Add descriptions of statistics to driver documentation. The statstics
      supported by the driver/controller map to IEEE and RFC statistics, and
      the names and mappings are described in the user documentation.
    - Change "unsigned int" to u32 in device structure definitions
    - Change used of netdev_warn to netif_warn in altera_sgdma.c
    - Change stat name rx_fifo_drops to ether_drops to match the event
      actually counted by the hardware.

V4: Address comments from V3 review
    - Change statistics names in ethtool module to follow common use in
      other ethernet drivers.
    - remove an unnecessary case in ethtool module
    - change logging to use netdev_* where possible instead of dev_*
    - remove logging for OOM errors since those are already logged

V3: Address comments from V2 review
    - Reorder patch submission so that net/ethernet Makefile and Kconfig
      are committed last, thus not breaking bisect
    - Use of_get_mac_address instead of of_get_property
    - Change supplemental and hash configuration bindings to boolean/empty,
      and more meaningful names
    - Add check for failure from calls to of_phy_connect and
      connect_local_phy
    - Correct code to find mdio child node
    - Update bindings document
    - Remove cast to u64 when not necessary
    - add use of const for statistics strings

V2: Address comments from initial RFC review.
    - The driver files were broken up by major sections of functionality.
      These include MSGDMA, SGDMA, Misc, and Main.
    - Add patch for MAINTAINERS file, add the maintainer for this submission
    - Use 32-bit lower/upper physical address accessor functions so the driver
      is 64-bit ready.
    - Use standard bindings where applicable. Especially phy-addr, and change
      "altr,rx-fifo-depth" to "rx-fifo-depth" and "altr,tx-fifo-depth" to
      "tx-fifo-depth".
    - Add use of max-frame-size property
    - Update bindings documents accordingly
    - Correct interrupt handler to use budget parameter in the convential way
    - Use macros consistently to define bit fields across files
    - Correct include exclusion macro in altera_msgdmahw.h (typo)
    - Remove use of barriers, these were not necessary since the DMA APIs
      ensure memory & buffer consistency
    - Remove use of netif_carrier_off in driver
    - move probing of phy from the open function to the probe function
    - use of_get_phy_mode instead of custom function
    - Use the .data field in the device structure to obtain a pointer
      to SGDMA or MSGDMA device specific properties and functions.
    - remove custom function to access devicetree since Altera specific
      bindings requiring it's use have been deprecated in favor of
      standard bindings.

The Altera TSE is a 10/100/1000 Mbps Ethernet soft IP component that can be
configured and synthesized using Quartus, and programmed into Altera FPGAs.
Two types of soft DMA IP components are supported by this driver - the Altera
SGDMA and the MSGDMA. The MSGDMA DMA component is preferred over the SGDMA,
since the SGDMA will be deprecated in favor of the MSGDMA. Software supporting
both is provided for customers still using the SGDMA and to demonstrate how
multiple types of DMA engines may be supported by the TSE driver in the event
customers wish to develop their own custom soft DMA engine for particular
applications.

The design has been tested on Altera's Cyclone 4, 5, and Cyclone 5 SOC
development kits using an ARM A9 processor and an Altera NIOS2 processor.
Differences in CPU/DMA coherency management and address alignment are
addressed by proper use of driver APIs and semantics.
