      net: atheros: atl1: use new api ethtool_{get|set}_link_ksettings · 1dae02b3
      Philippe Reynes authored 
      The ethtool api {get|set}_settings is deprecated.
We move this driver to new api {get|set}_link_ksettings.

The previous implementation of set_settings was modifying
the value of advertising, but with the new API, it's not
possible. The structure ethtool_link_ksettings is defined
as const.

      net: fix sleeping for sk_wait_event() · d9dc8b0f
      WANG Cong authored 
      Similar to commit 14135f30 ("inet: fix sleeping inside inet_wait_for_connect()"),
sk_wait_event() needs to fix too, because release_sock() is blocking,
it changes the process state back to running after sleep, which breaks
the previous prepare_to_wait().

Switch to the new wait API.

====================
Netfilter updates for net-next

The following patchset contains a second batch of Netfilter updates for
your net-next tree. This includes a rework of the core hook
infrastructure that improves Netfilter performance by ~15% according to
synthetic benchmarks. Then, a large batch with ipset updates, including
a new hash:ipmac set type, via Jozsef Kadlecsik. This also includes a
couple of assorted updates.

Regarding the core hook infrastructure rework to improve performance,
using this simple drop-all packets ruleset from ingress:

        nft add table netdev x
        nft add chain netdev x y { type filter hook ingress device eth0 priority 0\; }
        nft add rule netdev x y drop

And generating traffic through Jesper Brouer's
samples/pktgen/pktgen_bench_xmit_mode_netif_receive.sh script using -i
option. perf report shows nf_tables calls in its top 10:

    17.30%  kpktgend_0   [nf_tables]            [k] nft_do_chain
    15.75%  kpktgend_0   [kernel.vmlinux]       [k] __netif_receive_skb_core
    10.39%  kpktgend_0   [nf_tables_netdev]     [k] nft_do_chain_netdev

I'm measuring here an improvement of ~15% in performance with this
patchset, so we got +2.5Mpps more. I have used my old laptop Intel(R)
Core(TM) i5-3320M CPU @ 2.60GHz 4-cores.

This rework contains more specifically, in strict order, these patches:

1) Remove compile-time debugging from core.

2) Remove obsolete comments that predate the rcu era. These days it is
   well known that a Netfilter hook always runs under rcu_read_lock().

3) Remove threshold handling, this is only used by br_netfilter too.
   We already have specific code to handle this from br_netfilter,
   so remove this code from the core path.

4) Deprecate NF_STOP, as this is only used by br_netfilter.

5) Place nf_state_hook pointer into xt_action_param structure, so
   this structure fits into one single cacheline according to pahole.
   This also implicit affects nftables since it also relies on the
   xt_action_param structure.

6) Move state->hook_entries into nf_queue entry. The hook_entries
   pointer is only required by nf_queue(), so we can store this in the
   queue entry instead.

7) use switch() statement to handle verdict cases.

8) Remove hook_entries field from nf_hook_state structure, this is only
   required by nf_queue, so store it in nf_queue_entry structure.

9) Merge nf_iterate() into nf_hook_slow() that results in a much more
   simple and readable function.

10) Handle NF_REPEAT away from the core, so far the only client is
    nf_conntrack_in() and we can restart the packet processing using a
    simple goto to jump back there when the TCP requires it.
    This update required a second pass to fix fallout, fix from
    Arnd Bergmann.

11) Set random seed from nft_hash when no seed is specified from
    userspace.

12) Simplify nf_tables expression registration, in a much smarter way
    to save lots of boiler plate code, by Liping Zhang.

13) Simplify layer 4 protocol conntrack tracker registration, from
    Davide Caratti.

14) Missing CONFIG_NF_SOCKET_IPV4 dependency for udp4_lib_lookup, due
    to recent generalization of the socket infrastructure, from Arnd
    Bergmann.

15) Then, the ipset batch from Jozsef, he describes it as it follows:

* Cleanup: Remove extra whitespaces in ip_set.h
* Cleanup: Mark some of the helpers arguments as const in ip_set.h
* Cleanup: Group counter helper functions together in ip_set.h
* struct ip_set_skbinfo is introduced instead of open coded fields
  in skbinfo get/init helper funcions.
* Use kmalloc() in comment extension helper instead of kzalloc()
  because it is unnecessary to zero out the area just before
  explicit initialization.
* Cleanup: Split extensions into separate files.
* Cleanup: Separate memsize calculation code into dedicated function.
* Cleanup: group ip_set_put_extensions() and ip_set_get_extensions()
  together.
* Add element count to hash headers by Eric B Munson.
* Add element count to all set types header for uniform output
  across all set types.
* Count non-static extension memory into memsize calculation for
  userspace.
* Cleanup: Remove redundant mtype_expire() arguments, because
  they can be get from other parameters.
* Cleanup: Simplify mtype_expire() for hash types by removing
  one level of intendation.
* Make NLEN compile time constant for hash types.
* Make sure element data size is a multiple of u32 for the hash set
  types.
* Optimize hash creation routine, exit as early as possible.
* Make struct htype per ipset family so nets array becomes fixed size
  and thus simplifies the struct htype allocation.
* Collapse same condition body into a single one.
* Fix reported memory size for hash:* types, base hash bucket structure
  was not taken into account.
* hash:ipmac type support added to ipset by Tomasz Chilinski.
* Use setup_timer() and mod_timer() instead of init_timer()
  by Muhammad Falak R Wani, individually for the set type families.

16) Remove useless connlabel field in struct netns_ct, patch from
    Florian Westphal.

17) xt_find_table_lock() doesn't return ERR_PTR() anymore, so simplify
    {ip,ip6,arp}tables code that uses this.

dsa: mv88e6xxx: Fixes for port refactoring

The patches which refactored setting up the switch MACs introduced a
couple of regressions. The RGMII delays for a port can be set using
other mechanism than just phy-mode. Don't overwrite the delays unless
explicitly asked to. This broke my Armada 370 RD. Also, the mv88e6351
family supports setting RGMII delays, but is missing the necessary
entries in the ops structures to allow this.

These fixes are to patches currently in net-next. No need for stable
etc.

      The recent refactoring of setting the MAC configuration broke setting
of RGMII delays, via the phy-mode, on the 6351 family. Add the missing
ops to the structure.

      net: dsa: mv88e6xxx: Don't modify RGMII delays when not RGMII mode · fedf1865
      Andrew Lunn authored 
      The RGMII modes delays can be set via strapping pings or EEPROM.
Don't change them unless explicitly asked to change them.  The recent
refactoring of setting the MAC configuration changed this behaviours,
in that CPU and DSA ports have any pre-configured RGMII delays
removed. This breaks the Armada 370RD board. Restore the previous
behaviour, in that RGMII delays are only applied/removed when
explicitly asked for via an phy-mode being PHY_INTERFACE_MODE_RGMII*
