Pull pidfd fixes from Christian Brauner:
 "Userspace tools and libraries such as strace or glibc need a cheap and
  reliable way to tell whether CLONE_PIDFD is supported. The easiest way
  is to pass an invalid fd value in the return argument, perform the
  syscall and verify the value in the return argument has been changed
  to a valid fd.

  However, if CLONE_PIDFD is specified we currently check if pidfd == 0
  and return EINVAL if not.

  The check for pidfd == 0 was originally added to enable us to abuse
  the return argument for passing additional flags along with
  CLONE_PIDFD in the future.

  However, extending legacy clone this way would be a terrible idea and
  with clone3 on the horizon and the ability to reuse CLONE_DETACHED
  with CLONE_PIDFD there's no real need for this clutch. So remove the
  pidfd == 0 check and help userspace out.

  Also, accordig to Al, anon_inode_getfd() should only be used past the
  point of no failure and ksys_close() should not be used at all since
  it is far too easy to get wrong. Al's motto being "basically, once
  it's in descriptor table, it's out of your control". So Al's patch
  switches back to what we already had in v1 of the original patchset
  and uses a anon_inode_getfile() + put_user() + fd_install() sequence
  in the success path and a fput() + put_unused_fd() in the failure
  path.

  The other two changes should be trivial"

Pull AFS fixes from David Howells:
 "The in-kernel AFS client has been undergoing testing on opendev.org on
  one of their mirror machines. They are using AFS to hold data that is
  then served via apache, and Ian Wienand had reported seeing oopses,
  spontaneous machine reboots and updates to volumes going missing. This
  patch series appears to have fixed the problem, very probably due to
  patch (2), but it's not 100% certain.

  (1) Fix the printing of the "vnode modified" warning to exclude checks
      on files for which we don't have a callback promise from the
      server (and so don't expect the server to tell us when it
      changes).

      Without this, for every file or directory for which we still have
      an in-core inode that gets changed on the server, we may get a
      message logged when we next look at it. This can happen in bulk
      if, for instance, someone does "vos release" to update a R/O
      volume from a R/W volume and a whole set of files are all changed
      together.

      We only really want to log a message if the file changed and the
      server didn't tell us about it or we failed to track the state
      internally.

  (2) Fix accidental corruption of either afs_vlserver struct objects or
      the the following memory locations (which could hold anything).
      The issue is caused by a union that points to two different
      structs in struct afs_call (to save space in the struct). The call
      cleanup code assumes that it can simply call the cleanup for one
      of those structs if not NULL - when it might be actually pointing
      to the other struct.

      This means that every Volume Location RPC op is going to corrupt
      something.

  (3) Fix an uninitialised spinlock. This isn't too bad, it just causes
      a one-off warning if lockdep is enabled when "vos release" is
      called, but the spinlock still behaves correctly.

  (4) Fix the setting of i_block in the inode. This causes du, for
      example, to produce incorrect results, but otherwise should not be
      dangerous to the kernel"

d7ee287827 Generic DIM
From: Tal Gilboa and Yamin Fridman
 
 Implement net DIM over a generic DIM library, add RDMA DIM
 
 dim.h lib exposes an implementation of the DIM algorithm for
 dynamically-tuned interrupt moderation for networking interfaces.
 
 We want a similar functionality for other protocols, which might need to
 optimize interrupts differently. Main motivation here is DIM for NVMf
 storage protocol.
 
 Current DIM implementation prioritizes reducing interrupt overhead over
 latency. Also, in order to reduce DIM's own overhead, the algorithm might
 take some time to identify it needs to change profiles. While this is
 acceptable for networking, it might not work well on other scenarios.
 
 Here we propose a new structure to DIM. The idea is to allow a slightly
 modified functionality without the risk of breaking Net DIM behavior for
 netdev. We verified there are no degradations in current DIM behavior with
 the modified solution.
 
 Suggested solution:
 - Common logic is implemented in lib/dim/dim.c
 - Net DIM (existing) logic is implemented in lib/dim/net_dim.c, which uses
   the common logic in dim.c
 - Any new DIM logic will be implemented in "lib/dim/new_dim.c".
   This new implementation will expose modified versions of profiles,
   dim_step() and dim_decision().
 - DIM API is declared in include/linux/dim.h for all implementations.
 
 Pros for this solution are:
 - Zero impact on existing net_dim implementation and usage
 - Relatively more code reuse (compared to two separate solutions)
 - Increased extensibility

a653f2f538 net: dsa: qca8k: introduce reset via gpio feature
The QCA8337(N) has a RESETn signal on Pin B42 that
triggers a chip reset if the line is pulled low.
The datasheet says that: "The active low duration
must be greater than 10 ms".

This can hopefully fix some of the issues related
to pin strapping in OpenWrt for the EA8500 which
suffers from detection issues after a SoC reset.

Please note that the qca8k_probe() function does
currently require to read the chip's revision
register for identification purposes.

b2c709cce6 ipv6: Convert gateway validation to use fib6_info
Gateway validation does not need a dst_entry, it only needs the fib
entry to validate the gateway resolution and egress device. So,
convert ip6_nh_lookup_table from ip6_pol_route to fib6_table_lookup
and ip6_route_check_nh to use fib6_lookup over rt6_lookup.

ip6_pol_route is a call to fib6_table_lookup and if successful a call
to fib6_select_path. From there the exception cache is searched for an
entry or a dst_entry is created to return to the caller. The exception
entry is not relevant for gateway validation, so what matters are the
calls to fib6_table_lookup and then fib6_select_path.

Similarly, rt6_lookup can be replaced with a call to fib6_lookup with
RT6_LOOKUP_F_IFACE set in flags. Again, the exception cache search is
not relevant, only the lookup with path selection. The primary difference
in the lookup paths is the use of rt6_select with fib6_lookup versus
rt6_device_match with rt6_lookup. When you remove complexities in the
rt6_select path, e.g.,
1. saddr is not set for gateway validation, so RT6_LOOKUP_F_HAS_SADDR
   is not relevant
2. rt6_check_neigh is not called so that removes the RT6_NUD_FAIL_DO_RR
   return and round-robin logic.

the code paths are believed to be equivalent for the given use case -
validate the gateway and optionally given the device. Furthermore, it
aligns the validation with onlink code path and the lookup path actually
used for rx and tx.

Adjust the users, ip6_route_check_nh_onlink and ip6_route_check_nh to
handle a fib6_info vs a rt6_info when performing validation checks.

Existing selftests fib-onlink-tests.sh and fib_tests.sh are used to
verify the changes.

Vladimir Oltean says:

====================
FDB, VLAN and PTP fixes for SJA1105 DSA

This patchset is an assortment of fixes for the net-next version of the
sja1105 DSA driver:
- Avoid a kernel panic when the driver fails to probe or unregisters
- Finish Arnd Bermann's idea of compiling PTP support as part of the
  main DSA driver and not separately
- Better handling of initial port-based VLAN as well as VLANs for
  dsa_8021q FDB entries
- Fix address learning for the SJA1105 P/Q/R/S family
- Make static FDB entries persistent across switch resets
- Fix reporting of statically-added FDB entries in 'bridge fdb show'

d763778224 net: dsa: sja1105: Implement is_static for FDB entries on E/T
The first generation switches don't tell us through the dynamic config
interface whether the dumped FDB entries are static or not (the LOCKEDS
bit from P/Q/R/S).

However, now that we're keeping a mirror of all 'bridge fdb' commands in
the static config, this is an opportunity to compare a dumped FDB entry
to the driver's private database.  After all, what makes an entry static
is that *we* added it.

b3ee526a88 net: dsa: sja1105: Use correct dsa_8021q VIDs for FDB commands
A FDB entry means that "frames that match this VID and DMAC must be
forwarded to this port".

In the case of dsa_8021q however, the VID is not a single one (and
neither two, as my previous patch assumed). The VID can be set either by
the CPU port (1 tx_vid), or by any of the other front-panel port (n-1
rx_vid's).

17ae655540 net: dsa: sja1105: Populate is_static for FDB entries on P/Q/R/S
The reason why this wasn't tackled earlier is that I had hoped I
understood the user manual wrong.  But unfortunately hacks are required
in order to retrieve the static/dynamic nature of FDB entries on SJA1105
P/Q/R/S, since this info is stored in the writeback buffer of the
dynamic config command.

60f6053ff1 net: dsa: sja1105: Back up static FDB entries in kernel memory
After commit 8456721dd4 ("net: dsa: sja1105: Add support for
configuring address ageing time"), we started to reset the switch rather
often (each time the bridge core changes the ageing time on a switch
port).

The unfortunate reality is that SJA1105 doesn't have any {cold, warm,
whatever} reset mode in which it accepts a new configuration stream
without flushing the FDB.  Instead, in its world, the FDB *is* an
optional part of the static configuration.

So we play its game, and do what we also do for VLANs: for each 'bridge
fdb' command, we add the FDB entry through the dynamic interface, and we
append the in-kernel static config memory with info that we're going to
use later, when the next reset command is going to be issued.

The result is that 'bridge fdb' commands are now persistent (dynamically
learned entries are lost, but that's ok).

6c56e167cc net: dsa: sja1105: Make P/Q/R/S learn MAC addresses
At the end of the commit 1da7382134 ("net: dsa: sja1105: Add FDB
operations for P/Q/R/S series") message, I said that:

    At the moment only FDB entries installed statically through 'bridge fdb'
    are visible in the dump callback - the dynamically learned ones are
    still under investigation.

It looks like the reason why they were not visible in 'bridge fdb' was
that they were never learned - always flooded.

SJA1105 P/Q/R/S manual says about the MAXADDRP[port] field:

    Specify the maximum number of MAC address dynamically learned from
    the respective port. It is used to limit the number of learned MAC
    addresses per port.

It looks like not providing a value in the static config (aka providing
zeroes) is enough for it to not store the learned addresses in the FDB.

For now we divide the 1024 entry FDB "equally" amongst the 5 ports. This
may be revisited if the situation calls for that - for now I'm happy
that learning works.

e3502b8297 net: dsa: sja1105: Make vid 1 the default pvid
In SJA1105 there is no concept of 'default values' per se, everything
needs to be driver-supplied through the static configuration tables.

The issue is that the hardware manual says that 'at least the default
untagging VLAN' is mandatory to be provided through the static config.
But VLAN 0 isn't a very good initial pvid - its use is reserved for
priority-tagged frames, and the layers of the stack that care about
those already make sure that this VLAN is installed, as can be seen in
the message below:

  8021q: adding VLAN 0 to HW filter on device swp2

So change the pvid provided through the static configuration to 1, which
matches the bridge core's defaults.

with len = 1, 2 or 4. We can thus drop the if (len > SPI_TX_BUF_LEN)
check and we can also drop the allocation of the txbuf which is part
of the driver data and wastes 256 bytes for no reason. Regmap covers
the whole thing now.

Jeff Kirsher says:

====================
Intel Wired LAN Driver Updates 2019-06-26

This series contains updates to ixgbe and i40e only.

Mauro S. M. Rodrigues update the ixgbe driver to handle transceivers who
comply with SFF-8472 but do not implement the Digital Diagnostic
Monitoring (DOM) interface.  Update the driver to check the necessary
bits to see if DOM is implemented before trying to read the additional
256 bytes in the EEPROM for DOM data.

Young Xiao fixes a potential divide by zero issue in ixgbe driver.

Aleksandr fixes i40e to recognize 2.5 and 5.0 GbE link speeds so that it
is not reported as "Unknown bps".  Fixes the driver to read the firmware
LLDP agent status during DCB initialization, and to properly log the
LLDP agent status to help with debugging when DCB fails to initialize.

Martyna fixes i40e for the missing supported and advertised link modes
information in ethtool.

Jake fixes a function header comment that was incorrect for a PTP
function in i40e.

Maciej fixes an issue for i40e when a XDP program is loaded the
descriptor count gets reset to the default value, resolve the issue by
making the current descriptor count persistent across resets.

Alice corrects a copyright date which she found to be incorrect.

Piotr adds a log entry when the traffic class 0 is added or deleted, which
was not being logged previously.

Gustavo A. R. Silva updates i40e to use struct_size() where possible.

11d458c1cb batman-adv: mcast: apply optimizations for routable packets, too
Now that we not only track the presence of multicast listeners but also

61caf3d109 batman-adv: mcast: detect, distribute and maintain multicast router presence
To be able to apply our group aware multicast optimizations to packets
with a scope greater than link-local we need to not only keep track of
multicast listeners but also multicast routers.

With this patch a node detects the presence of multicast routers on
its segment by checking if
/proc/sys/net/ipv{4,6}/conf/<bat0|br0(bat)>/mc_forwarding is set for one
thing. This option is enabled by multicast routing daemons and needed
for the kernel's multicast routing tables to receive and route packets.

For another thing if a bridge is configured on top of bat0 then the
presence of an IPv6 multicast router behind this bridge is currently
detected by checking for an IPv6 multicast "All Routers Address"
(ff02::2). This should later be replaced by querying the bridge, which
performs proper, RFC4286 compliant Multicast Router Discovery (our
simplified approach includes more hosts than necessary, most notably
not just multicast routers but also unicast ones and is not applicable
for IPv4).

If no multicast router is detected then this is signalized via the new
BATADV_MCAST_WANT_NO_RTR4 and BATADV_MCAST_WANT_NO_RTR6
multicast tvlv flags.

3bcacd1e06 batman-adv: no need to check return value of debugfs_create functions
When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.

Because we don't care if debugfs works or not, this trickles back a bit
so we can clean things up by making some functions return void instead
of an error value that is never going to fail.

390dcd48cd batman-adv: mcast: avoid redundant multicast TT entries with bridges
When a bridge is added on top of bat0 we set the WANT_ALL_UNSNOOPABLES
flag. Which means we sign up for all traffic for ff02::1/128 and
224.0.0.0/24.

When the node itself had IPv6 enabled or joined a group in 224.0.0.0/24
itself then so far this would result in a multicast TT entry which is
redundant to the WANT_ALL_UNSNOOPABLES.

With this patch such redundant TT entries are avoided.
