Currently, when a VF requests queue configuration via
VIRTCHNL_OP_CONFIG_VSI_QUEUES the PF driver expects that this message
will only be called once and we always assume the queues being
configured start from 0. This is incorrect and is causing issues when
a VF tries to send this message for multiple queue blocks. Fix this by
using the queue_id specified in the virtchnl message and allowing for
individual Rx and/or Tx queues to be configured.
Also, reduce the duplicated for loops for configuring the queues by
moving all the logic into a single for loop.

If a VM reboots and/or VF driver is unloaded, its cached hardware MAC
address (hw_lan_addr.addr) is cleared in some cases. If the VF is
trusted, then the PF driver allows the VF to clear its old MAC address
even if this MAC was configured by a host administrator. If the VF is
untrusted, then the PF driver allows the VF to clear its old MAC
address only if the host admin did not set it.
For the trusted VF case, this is unexpected and will cause issues
because the host configured MAC (i.e. via XML) will be cleared on VM
reboot. For the untrusted VF case, this is done to be consistent and it
will allow the VF to keep the same MAC across VM reboot.
Fix this by introducing dev_lan_addr to the VF structure. This will be
the VF's MAC address when it's up and running and in most cases will be
the same as the hw_lan_addr. However, to address the VM reboot and
unload/reload problem, the driver will never allow the hw_lan_addr to be
cleared via VIRTCHNL_OP_DEL_ETH_ADDR. When the VF's MAC is changed, the
dev_lan_addr and hw_lan_addr will always be updated with the same value.
The only ways the VF's MAC can change are the following:
- Set the VF's MAC administratively on the host via iproute2.
- If the VF is trusted and changes/sets its own MAC.
- If the VF is untrusted and the host has not set the MAC via iproute2.

Currently there is no way for a VF driver to specify if it wants to
change it's hardware address. New bits are being added to virtchnl.h
in struct virtchnl_ether_addr that allow for the VF to correctly
communicate this information. However, legacy VF drivers that don't
support the new virtchnl.h bits still need to be supported. Make a
best effort attempt at saving the VF's primary/device address in the
legacy case and depend on the VIRTCHNL_ETHER_ADDR_PRIMARY type for
the new case.
Legacy case - If a unicast MAC is being added and the
hw_lan_addr.addr is empty, then populate it. This assumes that the
address is the VF's hardware address. If a unicast MAC is being
added and the hw_lan_addr.addr is not empty, then cache it in the
legacy_last_added_umac.addr. If a unicast MAC is being deleted and it
matches the hw_lan_addr.addr, then zero the hw_lan_addr.addr.
Also, if the legacy_last_added_umac.addr has not expired, copy the
legacy_last_added_umac.addr into the hw_lan_addr.addr. This is done
because we cannot guarantee the order of VIRTCHNL_OP_ADD_ETH_ADDR and
VIRTCHNL_OP_DEL_ETH_ADDR.
New case - If a unicast MAC is being added and it's specified as
VIRTCHNL_ETHER_ADDR_PRIMARY, then replace the current
hw_lan_addr.addr. If a unicast MAC is being deleted and it's type
is specified as VIRTCHNL_ETHER_ADDR_PRIMARY, then zero the
hw_lan_addr.addr.
Untrusted VFs - Only allow above legacy/new changes to their
hardware address if the PF has not set it administratively via
iproute2.
Trusted VFs - Always allow above legacy/new changes to their
hardware address even if the PF has administratively set it via
iproute2.
Also, change the variable dflt_lan_addr to hw_lan_addr to clearly
represent the purpose of this variable since it's purpose is to
act as a hardware programmed MAC address for the VF.

Currently, there is no way for a VF driver to specify that it wants to
change its device/primary unicast MAC address. This makes it
difficult/impossible for the PF driver to track the VF's device/primary
unicast MAC address, which is used for VM/VF reboot and displaying on
the host. Fix this by using 2 bits of a pad byte in the
virtchnl_ether_addr structure so the VF can specify what type of MAC
it's adding/deleting.
Below are the values that should be used by all VF drivers going
forward.
VIRTCHNL_ETHER_ADDR_LEGACY(0):
- The type should only ever be 0 for legacy AVF drivers (i.e.
drivers that don't support the new type bits). The PF drivers
will track VF's device/primary unicast MAC, but this will only
be a best effort.
VIRTCHNL_ETHER_ADDR_PRIMARY(1):
- This type should only be used when the VF is changing their
device/primary unicast MAC. It should be used for both delete
and add cases related to the device/primary unicast MAC.
VIRTCHNL_ETHER_ADDR_EXTRA(2):
- This type should be used when the VF is adding and/or deleting
MAC addresses that are not the device/primary unicast MAC. For
example, extra unicast addresses and multicast addresses
assuming the PF supports "extra" addresses at all.
If a PF is parsing the type field of the virtchnl_ether_addr, then it
should use the VIRTCHNL_ETHER_ADDR_TYPE_MASK to mask the first two bits
of the type field since 0, 1, and 2 are the only valid values.

The commit ae81feb7338c ("sch_htb: fix null pointer dereference
on a null new_q") fixes a NULL pointer dereference bug, but it
is not correct.
Because htb_graft_helper properly handles the case when new_q
is NULL, and after the previous patch by skipping this call
which creates an inconsistency : dev_queue->qdisc will still
point to the old qdisc, but cl->parent->leaf.q will point to
the new one (which will be noop_qdisc, because new_q was NULL).
The code is based on an assumption that these two pointers are
the same, so it can lead to refcount leaks.
The correct fix is to add a NULL pointer check to protect
qdisc_refcount_inc inside htb_parent_to_leaf_offload.

wireguard fixes for 5.13-rc5
Here are bug fixes to WireGuard for 5.13-rc5:
1-2,6) These are small, trivial tweaks to our test harness.
3) Linus thinks -O3 is still dangerous to enable. The code gen wasn't so
much different with -O2 either.
4) We were accidentally calling synchronize_rcu instead of
synchronize_net while holding the rtnl_lock, resulting in some rather
large stalls that hit production machines.
5) Peer allocation was wasting literally hundreds of megabytes on real
world deployments, due to oddly sized large objects not fitting
nicely into a kmalloc slab.
7-9) We move from an insanely expensive O(n) algorithm to a fast O(1)
algorithm, and cleanup a massive memory leak in the process, in
which allowed ips churn would leave danging nodes hanging around
without cleanup until the interface was removed. The O(1) algorithm
eliminates packet stalls and high latency issues, in addition to
bringing operations that took as much as 10 minutes down to less
than a second.

When removing single nodes, it's possible that that node's parent is an
empty intermediate node, in which case, it too should be removed.
Otherwise the trie fills up and never is fully emptied, leading to
gradual memory leaks over time for tries that are modified often. There
was originally code to do this, but was removed during refactoring in
2016 and never reworked. Now that we have proper parent pointers from
the previous commits, we can implement this properly.
In order to reduce branching and expensive comparisons, we want to keep
the double pointer for parent assignment (which lets us easily chain up
to the root), but we still need to actually get the parent's base
address. So encode the bit number into the last two bits of the pointer,
and pack and unpack it as needed. This is a little bit clumsy but is the
fastest and less memory wasteful of the compromises. Note that we align
the root struct here to a minimum of 4, because it's embedded into a
larger struct, and we're relying on having the bottom two bits for our
flag, which would only be 16-bit aligned on m68k.
The existing macro-based helpers were a bit unwieldy for adding the bit
packing to, so this commit replaces them with safer and clearer ordinary
functions.
We add a test to the randomized/fuzzer part of the selftests, to free
the randomized tries by-peer, refuzz it, and repeat, until it's supposed
to be empty, and then then see if that actually resulted in the whole
thing being emptied. That combined with kmemcheck should hopefully make
sure this commit is doing what it should. Along the way this resulted in
various other cleanups of the tests and fixes for recent graphviz.

The previous commit moved from O(n) to O(1) for removal, but in the
process introduced an additional pointer member to a struct that
increased the size from 60 to 68 bytes, putting nodes in the 128-byte
slab. With deployed systems having as many as 2 million nodes, this
represents a significant doubling in memory usage (128 MiB -> 256 MiB).
Fix this by using our own kmem_cache, that's sized exactly right. This
also makes wireguard's memory usage more transparent in tools like
slabtop and /proc/slabinfo.

Previously, deleting peers would require traversing the entire trie in
order to rebalance nodes and safely free them. This meant that removing
1000 peers from a trie with a half million nodes would take an extremely
long time, during which we're holding the rtnl lock. Large-scale users
were reporting 200ms latencies added to the networking stack as a whole
every time their userspace software would queue up significant removals.
That's a serious situation.
This commit fixes that by maintaining a double pointer to the parent's
bit pointer for each node, and then using the already existing node list
belonging to each peer to go directly to the node, fix up its pointers,
and free it with RCU. This means removal is O(1) instead of O(n), and we
don't use gobs of stack.
The removal algorithm has the same downside as the code that it fixes:
it won't collapse needlessly long runs of fillers. We can enhance that
in the future if it ever becomes a problem. This commit documents that
limitation with a TODO comment in code, a small but meaningful
improvement over the prior situation.
Currently the biggest flaw, which the next commit addresses, is that
because this increases the node size on 64-bit machines from 60 bytes to
68 bytes. 60 rounds up to 64, but 68 rounds up to 128. So we wind up
using twice as much memory per node, because of power-of-two
allocations, which is a big bummer. We'll need to figure something out
there.

With deployments having upwards of 600k peers now, this somewhat heavy
structure could benefit from more fine-grained allocations.
Specifically, instead of using a 2048-byte slab for a 1544-byte object,
we can now use 1544-byte objects directly, thus saving almost 25%
per-peer, or with 600k peers, that's a savings of 303 MiB. This also
makes wireguard's memory usage more transparent in tools like slabtop
and /proc/slabinfo.

Many of the synchronization points are sometimes called under the rtnl
lock, which means we should use synchronize_net rather than
synchronize_rcu. Under the hood, this expands to using the expedited
flavor of function in the event that rtnl is held, in order to not stall
other concurrent changes.
This fixes some very, very long delays when removing multiple peers at
once, which would cause some operations to take several minutes.

This adds support for SO_TIMESTAMP(NS). Timestamps are passed to
userspace in the same way as for plain tcp sockets.

MPTCP is builtin, so no need to add EXPORT_SYMBOL()s.
It will be used to support SO_TIMESTAMP(NS) ancillary
messages in the mptcp receive path.

Move the pre-check to the function that handles all SOL_SOCKET values.
At this point there is complete coverage for all values that were
accepted by the pre-check.
BUSYPOLL functions are accepted but will not have any functionality
yet until its clear how the expected mptcp behaviour should look like.

This adds support for TIMESTAMP(NS) setsockopt.
This doesn't make things work yet, because the mptcp receive path
doesn't convert the skb timestamps to cmsgs for userspace consumption.
receive path cmsg support is added ina followup patch.

This exports SO_TIMESTAMP_* function for re-use by MPTCP.
Without this there is too much copy & paste needed to support

Add HW VLAN acceleration protocol handling. In case of HW VLAN tagging,
we need that protocol available in the ndo_start_xmit(), so that it will be
stored in a new fields in the skb.
HW offloading is set to OFF by default.
Users are allow to turn on/off Rx/Tx HW VLAN acceleration via ethtool.

Complete to commit c8d4725e985d ("intel: Update drivers to use
ethtool_sprintf")
Update the igc driver to make use of ethtool_sprintf. The general idea
is to reduce code size and overhead by replacing the repeated pattern of
string printf statements and ETH_STRING_LEN counter increments.

On m68k, integers are aligned on addresses that are multiples of two,
not four, bytes. Hence the size of a structure containing integers may
not be divisible by 4.
Fix this by adding explicit padding.

Currently in the ice driver, the check whether to
allow a LLDP packet to egress the interface from the
PF_VSI is being based on the SKB's priority field.
It checks to see if the packets priority is equal to
TC_PRIO_CONTROL. Injected LLDP packets do not always
meet this condition.
SCAPY defaults to a sk_buff->protocol value of ETH_P_ALL
(0x0003) and does not set the priority field. There will
be other injection methods (even ones used by end users)
that will not correctly configure the socket so that
SKB fields are correctly populated.
Then ethernet header has to have to correct value for
the protocol though.
Add a check to also allow packets whose ethhdr->h_proto
matches ETH_P_LLDP (0x88CC).

Ethtool incorrectly reported supported and advertised auto-negotiation
settings for a backplane PHY image which did not support auto-negotiation.
This can occur when using media or PHY type for reporting ethtool
supported and advertised auto-negotiation settings.
Remove setting supported and advertised auto-negotiation settings based
on PHY type in ice_phy_type_to_ethtool(), and MAC type in
ice_get_link_ksettings().
Ethtool supported and advertised auto-negotiation settings should be
based on the PHY image using the AQ command get PHY capabilities with
media. Add setting supported and advertised auto-negotiation settings
based get PHY capabilities with media in ice_get_link_ksettings().
