We can miss FIB notifications sent between the time the ports were
created and the FIB notification block registered.
Instead of receiving these notifications only when they are replayed for
the FIB notification block during registration, just register the
notification block before the ports are created.

As explained in the previous commits, we need to process FIB entries
addition / deletion events in FIFO order or otherwise we can have a
mismatch between the kernel's FIB table and the device's.
Create an ordered workqueue for rocker to which these work items will be
submitted to.

FIB offload is currently done in process context with RTNL held, but
we're about to dump the FIB tables in RCU critical section, so we can no
longer sleep.
Instead, defer the operation to process context using deferred work. Make
sure fib info isn't freed while the work is queued by taking a reference
on it and releasing it after the operation is done.
Deferring the operation is valid because the upper layers always assume
the operation was successful. If it's not, then the driver-specific
abort mechanism is called and all routed traffic is directed to slow
path.
The work items are submitted to an ordered workqueue to prevent a
mismatch between the kernel's FIB table and the device's.

We're going to start processing FIB entries addition / deletion events
in deferred work. These work items must be processed in the order they
were submitted or otherwise we can have differences between the kernel's
FIB table and the device's.
Solve this by creating an ordered workqueue to which these work items
will be submitted to. Note that we can't simply convert the current
workqueue to be ordered, as EMADs re-transmissions are also processed in
deferred work.
Later on, we can migrate other work items to this workqueue, such as FDB
notification processing and nexthop resolution, since they all take the
same lock anyway.

As explained in the previous commit, modules are going to need to take a

The FIB notification chain is going to be converted to an atomic chain,
which means switchdev drivers will have to offload FIB entries in
deferred work, as hardware operations entail sleeping.
However, while the work is queued fib info might be freed, so a
reference must be taken. To release the reference (and potentially free
the fib info) fib_info_put() will be called, which in turn calls
free_fib_info().
Export free_fib_info() so that modules will be able to invoke
fib_info_put().

====================
40GbE Intel Wired LAN Driver Updates 2016-12-02
This series contains updates to i40e and i40evf only.
Alex provides changes so that we are much more robust about defining what
we can and cannot offload in i40e and i40evf by doing additional checks
other than L4 tunnel header length.
Jake provides several fixes/changes, first cleaning up a label that is
unnecessary, as well as cleaned up the use of a "magic number". Clarified
the code by separating the global private flags and the regular private
flags per interface into two arrays, so that future additions will not
produce duplication and buggy code. Adds additional checks to protect
against NULL values for msix_entries and q_vectors pointers.
Michal adds Clause22 method for accessing registers for some external
PHYs.
Piotr adds additional protocol support for the admin queue discover
capabilities function.
Tushar Dave fixes a panic seen on SPARC, where writel() should not be
used to write directly to a memory address but only to a memory mapped
I/O address otherwise it causes data access exceptions.
Joe Perches separates out a section of code into its own function, to
help reduce i40evf_reset_task() a bit.
Alan fixes an issue by checking for NULL before dereferencing msix_entries
and returning early in the case where it is NULL within the i40evf_close()
code path.
Henry provides code cleanup to remove unreachable and redundant sections
of code. Fixed up an issue where new NICs were not identifying "unknown
PHYs" correctly.
Harshitha fixes a issue where the ethtool "Supported Link" modes list
backplane interfaces on X722 devices for 10 GbE with SFP+ and Cortina
retimer, where these interfaces should not be visible to the user since
they cannot use them.
Carolyn changes an X722 informational message so that it only appears
when extra messages are desired.

Before commit 850cbaddb52d ("udp: use it's own memory accounting
schema"), the udp protocol allowed sk_rmem_alloc to grow beyond
the rcvbuf by the whole current packet's truesize. After said commit
we allow sk_rmem_alloc to exceed the rcvbuf only if the receive queue
is empty. As reported by Jesper this cause a performance regression
for some (small) values of rcvbuf.
This commit is intended to fix the regression restoring the old
handling of the rcvbuf limit.

Logically, EFX_BUG_ON_PARANOID can never be correct. For, BUG_ON should
only be used if it is not possible to continue without potential harm;
and since the non-DEBUG driver will continue regardless (as the BUG_ON is
compiled out), clearly the BUG_ON cannot be needed in the DEBUG driver.
So, replace every EFX_BUG_ON_PARANOID with either an EFX_WARN_ON_PARANOID
or the newly defined EFX_WARN_ON_ONCE_PARANOID.

samples, bpf: Refactor; Add automated tests for cgroups
These two patches are around refactoring out some old, reusable code from the

test.
There is some generic cgroupsv2 setup & cleanup code, given that most
environment still don't have it setup by default. With this code, we're able

This patch adds the sample program test_cgrp2_attach2. This program is
similar to test_cgrp2_attach, but it performs automated testing of the
cgroupv2 BPF attached filters. It runs the following checks:
* Simple filter attachment
* Application of filters to child cgroups
* Overriding filters on child cgroups
* Checking that this still works when the parent filter is removed
The filters that are used here are simply allow all / deny all filters, so
it isn't checking the actual functionality of the filters, but rather
the behaviour around detachment / attachment. If net_cls is enabled,
this test will fail.

net_generic() function is both a) inline and b) used ~600 times.
It has the following code inside
...
ptr = ng->ptr[id - 1];
...
"id" is never compile time constant so compiler is forced to subtract 1.
And those decrements or LEA [r32 - 1] instructions add up.
We also start id'ing from 1 to catch bugs where pernet sybsystem id
is not initialized and 0. This is quite pointless idea (nothing will
work or immediate interference with first registered subsystem) in
general but it hints what needs to be done for code size reduction.
Namely, overlaying allocation of pointer array and fixed part of
structure in the beginning and using usual base-0 addressing.
Ids are just cookies, their exact values do not matter, so lets start
with 3 on x86_64.

Publishing net_generic pointer is done with silly mistake: new array is
published BEFORE setting freshly acquired pernet subsystem pointer.
memcpy
rcu_assign_pointer
kfree_rcu
ng->ptr[id - 1] = data;
This bug was introduced with commit dec827d174d7f76c457238800183ca864a639365
("[NETNS]: The generic per-net pointers.") in the glorious days of
chopping networking stack into containers proper 8.5 years ago (whee...)
How it didn't trigger for so long?
Well, you need quite specific set of conditions:
*) race window opens once per pernet subsystem addition
(read: modprobe or boot)
*) not every pernet subsystem is eligible (need ->id and ->size)
*) not every pernet subsystem is vulnerable (need incorrect or absense
of ordering of register_pernet_sybsys() and actually using net_generic())
*) to hide the bug even more, default is to preallocate 13 pointers which
is actually quite a lot. You need IPv6, netfilter, bridging etc together
loaded to trigger reallocation in the first place. Trimmed down
config are OK.

nla_ok() consists of 3 clauses:
1) int rem >= (int)sizeof(struct nlattr)
2) u16 nla_len >= sizeof(struct nlattr)
3) u16 nla_len <= int rem
The statement is that clause (1) is redundant.
What it does is ensuring that "rem" is a positive number,
so that in clause (3) positive number will be compared to positive number
with no problems.
However, "u16" fully fits into "int" and integers do not change value
when upcasting even to signed type. Negative integers will be rejected
by clause (3) just fine. Small positive integers will be rejected
by transitivity of comparison operator.
NOTE: all of the above DOES NOT apply to nlmsg_ok() where ->nlmsg_len is
u32(!), so 3 clauses AND A CAST TO INT are necessary.

As David Miller pointed out for for the previous patch, the whitespace
in some functions looks rather odd. This was caused by commit 6329da5f258a
("obsolete config in kernel source: USE_INTERNAL_TIMER"), which removed
some conditions but did not reindent the code.
This fixes the indentation in the file and removes extraneous whitespace
at the end of the lines and before tabs.
There are many other minor coding style problems in the driver, but I'm

Couple conflicts resolved here:
1) In the MACB driver, a bug fix to properly initialize the
RX tail pointer properly overlapped with some changes
to support variable sized rings.
2) In XGBE we had a "CONFIG_PM" --> "CONFIG_PM_SLEEP" fix
overlapping with a reorganization of the driver to support
ACPI, OF, as well as PCI variants of the chip.
3) In 'net' we had several probe error path bug fixes to the
stmmac driver, meanwhile a lot of this code was cleaned up
and reorganized in 'net-next'.
4) The cls_flower classifier obtained a helper function in
'net-next' called __fl_delete() and this overlapped with
Daniel Borkamann's bug fix to use RCU for object destruction
in 'net'. It also overlapped with Jiri's change to guard
the rhashtable_remove_fast() call with a check against
tc_skip_sw().
5) In mlx4, a revert bug fix in 'net' overlapped with some
unrelated changes in 'net-next'.
6) In geneve, a stale header pointer after pskb_expand_head()
bug fix in 'net' overlapped with a large reorganization of
the same code in 'net-next'. Since the 'net-next' code no
longer had the bug in question, there was nothing to do
other than to simply take the 'net-next' hunks.

sets the promiscuous mode based on when broadcast filters are added or
removed.
I40E_VLAN_ANY will request a broadcast filter for all VLANs, (as we're
in untagged mode) while a broadcast filter on a specific VLAN will only
request broadcast for that VLAN.
Thus, we restore addition of broadcast filter to the array, but we add
special handling for these such that they enable the broadcast
promiscuous mode instead of being sent as regular filters.
The end result is that we will correctly receive all broadcast packets
(even those with a *source* address equal to the broadcast address) but
will not receive packets for which we don't have an active VLAN filter.

This patch fixes the problem where the ethtool Supported link
modes list backplane interfaces on X722 devices for 10GbE with
SFP+ and Cortina retimer. This patch fixes the problem by setting
and using a flag for this particular device since the backplane
interface is only between the internal PHY and the retimer and it
should not be seen by the user as they cannot use it.
Without this patch, the user wrongly thinks that backplane interfaces
are supported on their device when they actually are not.

Update the functions which free msix_entries and q_vectors so that they
are safe against NULL values. This allows calling code to not care
whether these have already been freed when disabling and freeing them.

The PHY type value for unrecognized PHYs and cables was changed
based on firmware version number. Newer hardware use lower firmware
version numbers and this was causing some PHYs to be identified
as type 0x16 instead of 0xe (unknown).
Without this patch, newer card will incorrectly identify unknown
PHYs and cables.
This change adds hardware type to the check for firmware version
so the PHY type is reported correctly.

The code at the end of i40e_read_phy_register_clause22() contained
unreachable code and redundant control statements.
This change removes the unreachable code. And deletes the redundant
goto statement and if statement.

It is possible for msix_entries to be freed by a previous suspend/remove
before a VF is closed. This patch fixes the issue by checking for NULL
before dereferencing msix_entries and returning early in the case where
it is NULL within the i40evf_close code path. Without this patch it is
possible to trigger a kernel panic through NULL dereference.
