854da99173 ipv4: Allow sending multicast packets on specific i/f using VRF socket
It is useful to be able to use the same socket for listening in a
specific VRF, as for sending multicast packets out of a specific
interface. However, the bound device on the socket currently takes
precedence and results in the packets not being sent.

Relax the condition on overriding the output interface to use for
sending packets out of UDP, raw and ping sockets to allow multicast
packets to be sent using the specified multicast interface.

6919622af3 bridge: mcast: Default back to multicast enabled state
Commit 13cefad2f2c1 ("net: bridge: convert and rename mcast disabled")
converted the 'multicast_disabled' field to an option bit named
'BROPT_MULTICAST_ENABLED'.

While the old field was implicitly initialized to 0, the new field is
not initialized, resulting in the bridge defaulting to multicast
disabled state and breaking existing applications.

Fix this by explicitly initializing the option.

====================
dpaa2-eth: Add support for Rx flow classification

The Management Complex (MC) firmware initially allowed the
configuration of a single key to be used both for Rx flow hashing
and flow classification. This prevented us from supporting
Rx flow classification independently of the hash key configuration.

Newer firmware versions expose separate commands for
configuring the two types of keys, so we can use them to
introduce Rx classification support. For frames that don't match
any classification rule, we fall back to statistical distribution
based on the current hash key.

The first patch in this set updates the Rx hashing code to use
the new firmware API for key config. Subsequent patches introduce
the firmware API for configuring the classification and actual
support for adding and deleting rules via ethtool.

afb90dbb5f dpaa2-eth: Add ethtool support for flow classification
Add support for inserting and deleting Rx flow classification
rules through ethtool.

We support classification based on some header fields for
flow-types ether, ip4, tcp4, udp4 and sctp4.

Rx queues are core affine, so the action argument effectively
selects on which cpu the matching frame will be processed.
Discarding the frame is also supported.

4aaaf9b95a dpaa2-eth: Configure Rx flow classification key
For firmware versions that support it, configure an Rx flow
classification key at probe time.

Hardware expects all rules in the classification table to share
the same key. So we setup a key containing all supported fields
at driver init and when a user adds classification rules through
ethtool, we will just mask out the unused header fields.

Since the key composition process is the same for flow
classification and hashing, reuse existing code where possible.

drivers using the usbnet.c core all declare their information as const
and the usbnet.c itself does not try and modify the struct.

It is therefore a good idea to make this const in the usbnet.c structure
in case anyone tries to modify it.

tcp_get_info() will acquire the socket lock for a short amount

45ec318578 net: systemport: Fix wake-up interrupt race during resume
The AON_PM_L2 is normally used to trigger and identify the source of a
wake-up event. Since the RX_SYS clock is no longer turned off, we also
have an interrupt being sent to the SYSTEMPORT INTRL_2_0 controller, and
that interrupt remains active up until the magic packet detector is
disabled which happens much later during the driver resumption.

The race happens if we have a CPU that is entering the SYSTEMPORT
INTRL2_0 handler during resume, and another CPU has managed to clear the
wake-up interrupt during bcm_sysport_resume_from_wol(). In that case, we
have the first CPU stuck in the interrupt handler with an interrupt
cause that has been cleared under its feet, and so we keep returning
IRQ_NONE and we never make any progress.

This was not a problem before because we would always turn off the
RX_SYS clock during WoL, so the SYSTEMPORT INTRL2_0 would also be turned
off as well, thus not latching the interrupt.

The fix is to make sure we do not enable either the MPD or
BRCM_TAG_MATCH interrupts since those are redundant with what the
AON_PM_L2 interrupt controller already processes and they would cause
such a race to occur.

0e1d6eca51 rtnl: limit IFLA_NUM_TX_QUEUES and IFLA_NUM_RX_QUEUES to 4096
We have an impressive number of syzkaller bugs that are linked
to the fact that syzbot was able to create a networking device
with millions of TX (or RX) queues.

Let's limit the number of RX/TX queues to 4096, this really should
cover all known cases.

A separate patch will add various cond_resched() in the loops
handling sysfs entries at device creation and dismantle.

Tested:

lpaa6:~# ip link add gre-4097 numtxqueues 4097 numrxqueues 4097 type ip6gretap
RTNETLINK answers: Invalid argument

lpaa6:~# time ip link add gre-4096 numtxqueues 4096 numrxqueues 4096 type ip6gretap

0f3b914c9c bonding: fix warning message
RX queue config for bonding master could be different from its slave
device(s). With the commit 6a9e461f6fe4 ("bonding: pass link-local
packets to bonding master also."), the packet is reinjected into stack
with skb->dev as bonding master. This potentially triggers the
message:

   "bondX received packet on queue Y, but number of RX queues is Z"

whenever the queue that packet is received on is higher than the
numrxqueues on bonding master (Y > Z).

2ab2ddd301 inet: make sure to grab rcu_read_lock before using ireq->ireq_opt
Timer handlers do not imply rcu_read_lock(), so my recent fix
triggered a LOCKDEP warning when SYNACK is retransmit.

Lets add rcu_read_lock()/rcu_read_unlock() pairs around ireq->ireq_opt
usages instead of guessing what is done by callers, since it is
not worth the pain.

Get rid of ireq_opt_deref() helper since it hides the logic
without real benefit, since it is now a standard rcu_dereference().

Jeff Kirsher says:

====================
100GbE Intel Wired LAN Driver Updates 2018-10-02

This series contains updates to ice driver only.

Anirudh expands the use of VSI handles across the rest of the driver,
which includes refactoring the code to correctly use VSI handles.  After
a reset, ensure that all configurations for a VSI get re-applied before
moving on to rebuilding the next VSI.

Dave fixed the driver to check the current link state after reset to
ensure that the correct link state of a port is reported.  Fixed an
issue where if the driver is unloaded when traffic is in progress,
errors are generated.

Preethi breaks up the IRQ tracker into a software and hardware IRQ
tracker, where the software IRQ tracker tracks only the PF's IRQ
requests and does not play any role in the VF initialization.  The
hardware IRQ tracker represents the device's interrupt space and will be
looked up to see if the device has run our of interrupts when a
interrupt has to be allocated in the device for either PF or VF.

Md Fahad adds support for enabling/disabling RSS via ethtool.

Brett aligns the ice_reset_req enum values to the values that the
hardware understands.  Also added initial support for dynamic interrupt
moderation in the ice driver.

fe3a83af6a declance: Fix continuation with the adapter identification message
Fix a commit 4bcc595ccd80 ("printk: reinstate KERN_CONT for printing
continuation lines") regression with the `declance' driver, which caused
the adapter identification message to be split between two lines, e.g.:

declance.c: v0.011 by Linux MIPS DECstation task force
tc6: PMAD-AA
, addr = 08:00:2b:1b:2a:6a, irq = 14
tc6: registered as eth0.

Address that properly, by printing identification with a single call,
making the messages now look like:

declance.c: v0.011 by Linux MIPS DECstation task force
tc6: PMAD-AA, addr = 08:00:2b:1b:2a:6a, irq = 14

During certain heavy network loads TX could time out

TX is sometimes never restarted after reaching
"tx_stop_threshold" because function "fec_enet_tx_queue"

In addition the TX timeout callback function failed to

9e4ab4c29a ice: Add support for dynamic interrupt moderation
Currently there is no support for dynamic interrupt moderation. This
patch adds some initial code to support this. The following changes
were made:

1. Currently we are using multiple members to store the interrupt
   granularity (itr_gran_25/50/100/200). This is not necessary because
   we can query the device to determine what the interrupt granularity
   should be set to, done by a new function ice_get_itr_intrl_gran.

2. Added intrl to ice_q_vector structure to support interrupt rate
   limiting.

3. Added the function ice_intrl_usecs_to_reg for converting to a value
   in usecs that the device understands.

4. Added call to write to the GLINT_RATE register. Disable intrl by
   default for now.

5. Changed rx/tx_itr_setting to itr_setting because having both seems
   redundant because a ring is either Tx or Rx.

6. Initialize itr_setting for both Tx/Rx rings in ice_vsi_alloc_rings()
