f7ad68bf98 rhashtable: rename rht_for_each*continue as *from.
The pattern set by list.h is that for_each..continue()
iterators start at the next entry after the given one,
while for_each..from() iterators start at the given
entry.

The rht_for_each*continue() iterators are documented as though the
start at the 'next' entry, but actually start at the given entry,
and they are used expecting that behaviour.
So fix the documentation and change the names to *from for consistency
with list.h

4feb7c7a4f rhashtable: don't hold lock on first table throughout insertion.
rhashtable_try_insert() currently holds a lock on the bucket in
the first table, while also locking buckets in subsequent tables.
This is unnecessary and looks like a hold-over from some earlier
version of the implementation.

As insert and remove always lock a bucket in each table in turn, and
as insert only inserts in the final table, there cannot be any races
that are not covered by simply locking a bucket in each table in turn.

When an insert call reaches that last table it can be sure that there
is no matchinf entry in any other table as it has searched them all, and
insertion never happens anywhere but in the last table.  The fact that
code tests for the existence of future_tbl while holding a lock on
the relevant bucket ensures that two threads inserting the same key
will make compatible decisions about which is the "last" table.

This simplifies the code and allows the ->rehash field to be
discarded.

We still need a way to ensure that a dead bucket_table is never
re-linked by rhashtable_walk_stop().  This can be achieved by calling
call_rcu() inside the locked region, and checking with
rcu_head_after_call_rcu() in rhashtable_walk_stop() to see if the
bucket table is empty and dead.

====================
net: phy: Move Omega PHY entry to Cygnus PHY driver

In order to pave the way for adding some specific Omega PHY features
that may not be desirable on other products covered by the bcm7xxx PHY
driver, split the Omega PHY entry into the Cygnus PHY driver such that
the PHY drivers are reflective of product lines/business units
maintaining them within Broadcom.

No functional changes intended.

17cc982176 net: phy: Move Omega PHY entry to Cygnus PHY driver
Cygnus and Omega are part of the same business unit and product line, it
makes sense to group PHY entries by products such that a platform can
select only the drivers that it needs. Bring all the functionality that
the BCM7XXX_28NM_GPHY() macro hides for us and remove the Omega PHY
entry from bcm7xxx.c.

As an added bonus, we now have a proper mdio_device_id entry to permit
auto-loading.

9ab948a91b ipv4: Allow amount of dirty memory from fib resizing to be controllable
fib_trie implementation calls synchronize_rcu when a certain amount of
pages are dirty from freed entries. The number of pages was determined
experimentally in 2009 (commit c3059477fc).

At the current setting, synchronize_rcu is called often -- 51 times in a
second in one test with an average of an 8 msec delay adding a fib entry.
The total impact is a lot of slow down modifying the fib. This is seen
in the output of 'time' - the difference between real time and sys+user.
For example, using 720,022 single path routes and 'ip -batch'[1]:

    $ time ./ip -batch ipv4/routes-1-hops
    real    0m14.214s
    user    0m2.513s
    sys     0m6.783s

So roughly 35% of the actual time to install the routes is from the ip
command getting scheduled out, most notably due to synchronize_rcu (this
is observed using 'perf sched timehist').

This patch makes the amount of dirty memory configurable between 64k where
the synchronize_rcu is called often (small, low end systems that are memory
sensitive) to 64M where synchronize_rcu is called rarely during a large
FIB change (for high end systems with lots of memory). The default is 512kB
which corresponds to the current setting of 128 pages with a 4kB page size.

As an example, at 16MB the worst interval shows 4 calls to synchronize_rcu
in a second blocking for up to 30 msec in a single instance, and a total
of almost 100 msec across the 4 calls in the second. The trade off is
allowing FIB entries to consume more memory in a given time window but
but with much better fib insertion rates (~30% increase in prefixes/sec).
With this patch and net.ipv4.fib_sync_mem set to 16MB, the same batch
file runs in:

    $ time ./ip -batch ipv4/routes-1-hops
    real    0m9.692s
    user    0m2.491s
    sys     0m6.769s

So the dead time is reduced to about 1/2 second or <5% of the real time.

[1] 'ip' modified to not request ACK messages which improves route
    insertion times by about 20%

0c3e0e3bb6 tun: Add ioctl() TUNGETDEVNETNS cmd to allow obtaining real net ns of tun device
In commit f2780d6d74 "tun: Add ioctl() SIOCGSKNS cmd to allow
obtaining net ns of tun device" it was missed that tun may change
its net ns, while net ns of socket remains the same as it was
created initially. SIOCGSKNS returns net ns of socket, so it is
not suitable for obtaining net ns of device.

We may have two tun devices with the same names in two net ns,
and in this case it's not possible to determ, which of them
fd refers to (TUNGETIFF will return the same name).

This patch adds new ioctl() cmd for obtaining net ns of a device.

c7a1ce397a ipv6: Change addrconf_f6i_alloc to use ip6_route_info_create
Change addrconf_f6i_alloc to generate a fib6_config and call
ip6_route_info_create. addrconf_f6i_alloc is the last caller to
fib6_info_alloc besides ip6_route_info_create, and there is no
reason for it to do its own initialization on a fib6_info.

Host routes need to be created even if the device is down, so add a
new flag, fc_ignore_dev_down, to fib6_config and update fib6_nh_init
to not error out if device is not up.

Notes on the conversion:
- ip_fib_metrics_init is the same as fib6_config has fc_mx set to NULL
  and fc_mx_len set to 0
- dst_nocount is handled by the RTF_ADDRCONF flag
- dst_host is handled by fc_dst_len = 128

nh_gw does not get set after the conversion to ip6_route_info_create
but it should not be set in addrconf_f6i_alloc since this is a host
route not a gateway route.

Everything else is a straight forward map between fib6_info and
fib6_config.

reordering that happen in between different nodes.
Unfortunately, we forgot checking at receiving side to ignore intra node.

We fix this by checking and returning if arrived message from intra node.

====================
net: refactor ndo_select_queue()

Currently, on most devices implementing ndo_select_queue(), we get 2
indirect calls per xmit packet, at least in some scenarios.

We can avoid one of such indirect calls refactoring the ndo_select_queue()
usage so that we don't need anymore the 'fallback' argument.

The first patch renames a helper used later as a public API, the second one
changes the af packet implementation so that it uses the common infrastructure
to select the xmit queue, and the second patch drops the now unneeded argument
from ndo_select_queue().

Alternatively we could use the INDIRECT_CALL_WRAPPER infrastructure to avoid
the fallback indirect call in the common case, but this solution allows also
for some code cleanup.

 v1 -> v2:
  - renamed select queue helpers, as per Eric's and David's suggestions

a350eccee5 net: remove 'fallback' argument from dev->ndo_select_queue()
After the previous patch, all the callers of ndo_select_queue()
provide as a 'fallback' argument netdev_pick_tx.
The only exceptions are nested calls to ndo_select_queue(),
which pass down the 'fallback' available in the current scope
- still netdev_pick_tx.

We can drop such argument and replace fallback() invocation with
netdev_pick_tx(). This avoids an indirect call per xmit packet
in some scenarios (TCP syn, UDP unconnected, XDP generic, pktgen)
with device drivers implementing such ndo. It also clean the code
a bit.

Tested with ixgbe and CONFIG_FCOE=m

With pktgen using queue xmit:

b71b5837f8 packet: rework packet_pick_tx_queue() to use common code selection
Currently packet_pick_tx_queue() is the only caller of
ndo_select_queue() using a fallback argument other than
netdev_pick_tx.

Leveraging rx queue, we can obtain a similar queue selection
behavior using core helpers. After this change, ndo_select_queue()
is always invoked with netdev_pick_tx() as fallback.
We can change ndo_select_queue() signature in a followup patch,
dropping an indirect call per transmitted packet in some scenarios
(e.g. TCP syn and XDP generic xmit)

This changes slightly how af packet queue selection happens when
PACKET_QDISC_BYPASS is set. It's now more similar to plan dev_queue_xmit()
tacking in account both XPS and TC mapping.

 v1  -> v2:
  - rebased after helper name change

  - initialize sender_cpu to the expected value

f295b3ae9f net/tls: Add support of AES128-CCM based ciphers
Added support for AES128-CCM based record encryption. AES128-CCM is
similar to AES128-GCM. Both of them have same salt/iv/mac size. The
notable difference between the two is that while invoking AES128-CCM
operation, the salt||nonce (which is passed as IV) has to be prefixed
with a hardcoded value '2'. Further, CCM implementation in kernel
requires IV passed in crypto_aead_request() to be full '16' bytes.
Therefore, the record structure 'struct tls_rec' has been modified to
reserve '16' bytes for IV. This works for both GCM and CCM based cipher.

5c5f626bca net: phy: improve handling link_change_notify callback
Currently the Phy driver's link_change_notify callback is called
whenever the state machine is run (every second if polling), no matter
whether the state changed or not. This isn't needed and may confuse
users considering the name of the callback. Actually it contradicts
its kernel-doc description. Therefore let's change the behavior and
call this callback only in case of an actual state change.

This requires changes to the at803x and rockchip drivers.
at803x can be simplified so that it reacts on a state change to
PHY_NOLINK only.
The rockchip driver can also be much simplified. We simply re-init
the AFE/DSP registers whenever we change to PHY_RUNNING and speed
is 100Mbps. This causes very small overhead because we do this even
if the speed was 100Mbps already. But this is negligible and
I think justified by the much simpler code.

Changes are compile-tested only.

A little bit problematic seems to be to find somebody with the
hardware to test the changes to the two PHY drivers. See also [0].
David may be able to test the Rockchip driver.

100GbE Intel Wired LAN Driver Updates 2019-03-19

This series contains updates to ice driver only.

Michal adds support for the pruning enable flag to avoid seeing

Akeem fixes an issue with VF queues being disabled and the VF netdev
network carrier being lost after reset. Fixed an issue issue when doing
PFR and CORER resets, where all VF VSIs need to be reset and rebuilt
with the main VSIs before replaying all VSIs.  Resolved an issue to
properly initialize VFs in the guest OS via PCI passthrough.

Bruce adds a local variable to avoid unnecessary de-references
throughout ice_probe().

Brett cleans up the code a bit by removing the need for a local variable
and re-designs the loop to simply return when get a successful result.
Cleans up the code to replace loop calls with a predefined macro to make
the code more consistent.  Updated the driver to ensure ITR granularity
is always 2 usecs. Refactors the calculation of VSIs per PF into a
general function that can calculate per PF allocations for not just VSIs
but across multiple resource types.  Improve the driver performance of
the driver when using the default settings by determining the ring size
and the number of descriptors for transmit and receive based on a
calculation with the PAGE_SIZE, ICE_MAX_NUM_DESC, and
ICE_REQ_DESC_MULTIPLE.

Chinh fixes an issue, where a reserved bit was possibly being set when
it should never be set.

ad71b256ba ice: Determine descriptor count and ring size based on PAGE_SIZE

default. For Rx this amounts to a full page (assuming 4K pages) because
each Rx descriptor is 32 Bytes, but for Tx it only amounts to a half
page because each Tx descriptor is 16 Bytes (assuming 4K pages).
Instead of assuming 4K pages, determine the ring size and the number of
