afs_vol_interest objects represent the volume IDs currently being accessed
from a fileserver. These hold lists of afs_cb_interest objects that
repesent the superblocks using that volume ID on that server.
When a callback notification from the server telling of a modification by
another client arrives, the volume ID specified in the notification is
looked up in the server's afs_vol_interest list. Through the
afs_cb_interest list, the relevant superblocks can be iterated over and the
specific inode looked up and marked in each one.
Make the following efficiency improvements:
(1) Hold rcu_read_lock() over the entire processing rather than locking it
each time.
(2) Do all the callbacks for each vid together rather than individually.
Each volume then only needs to be looked up once.
(3) afs_vol_interest objects are now stored in an rb_tree rather than a
flat list to reduce the lookup step count.
(4) afs_vol_interest lookup is now done with RCU, but because it's in an
rb_tree which may rotate under us, a seqlock is used so that if it
changes during the walk, we repeat the walk with a lock held.
With this and the preceding patch which adds RCU-based lookups in the inode
cache, target volumes/vnodes can be taken without the need to take any
locks, except on the target itself.

When an AFS client accesses a file, it receives a limited-duration callback
promise that the server will notify it if another client changes a file.
This callback duration can be a few hours in length.
If a client mounts a volume and then an application prevents it from being
unmounted, say by chdir'ing into it, but then does nothing for some time,
the rxrpc_peer record will expire and rxrpc-level keepalive will cease.
If there is NAT or a firewall between the client and the server, the route
back for the server may close after a comparatively short duration, meaning
that attempts by the server to notify the client may then bounce.
The client, however, may (so far as it knows) still have a valid unexpired
promise and will then rely on its cached data and will not see changes made
on the server by a third party until it incidentally rechecks the status or
the promise needs renewal.
To deal with this, the client needs to regularly probe the server. This
has two effects: firstly, it keeps a route open back for the server, and
secondly, it causes the server to disgorge any notifications that got
queued up because they couldn't be sent.
Fix this by adding a mechanism to emit regular probes.
Two levels of probing are made available: Under normal circumstances the
'slow' queue will be used for a fileserver - this just probes the preferred
address once every 5 mins or so; however, if server fails to respond to any
probes, the server will shift to the 'fast' queue from which all its
interfaces will be probed every 30s. When it finally responds, the record
will switch back to the slow queue.
Further notes:
(1) Probing is now no longer driven from the fileserver rotation
algorithm.
(2) Probes are dispatched to all interfaces on a fileserver when that an
afs_server object is set up to record it.
(3) The afs_server object is removed from the probe queues when we start
to probe it. afs_is_probing_server() returns true if it's not listed
- ie. it's undergoing probing.
(4) The afs_server object is added back on to the probe queue when the
final outstanding probe completes, but the probed_at time is set when
we're about to launch a probe so that it's not dependent on the probe
duration.
(5) The timer and the work item added for this must be handed a count on
net->servers_outstanding, which they hand on or release. This makes
sure that network namespace cleanup waits for them.

Split the usage count on the afs_server struct to have an active count that
registers who's actually using it separately from the reference count on
the object.
This allows a future patch to dispatch polling probes without advancing the
"unuse" time into the future each time we emit a probe, which would
otherwise prevent unused server records from expiring.
Included in this:
(1) The latter part of afs_destroy_server() in which the RCU destruction
of afs_server objects is invoked and the outstanding server count is
decremented is split out into __afs_put_server().
(2) afs_put_server() now calls __afs_put_server() rather then setting the
management timer.
(3) The calls begun by afs_fs_give_up_all_callbacks() and
afs_fs_get_capabilities() can now take a ref on the server record, so
afs_destroy_server() can just drop its ref and needn't wait for the
completion of these calls. They'll put the ref when they're done.
(4) Because of (3), afs_fs_probe_done() no longer needs to wake up
afs_destroy_server() with server->probe_outstanding.
(5) afs_gc_servers can be simplified. It only needs to check if
server->active is 0 rather than playing games with the refcount.
(6) afs_manage_servers() can propose a server for gc if usage == 0 rather
than if ref == 1. The gc is effected by (5).

The U-version VLDB volume record retrieved by the VL.GetEntryByNameU rpc op
carries a change counter (the serverUnique field) for each fileserver
listed in the record as backing that volume. This is incremented whenever
the registration details for a fileserver change (such as its address
list). Note that the same value will be seen in all UVLDB records that
refer to that fileserver.
This should be checked before calling the VL server to re-query the address
list for a fileserver. If it's the same, there's no point doing the query.

When a lookup is done in an AFS directory, the filesystem will speculate
and fetch up to 49 other statuses for files in the same directory and fetch
those as well, turning them into inodes or updating inodes that already
exist.
However, occasionally, a callback break might go missing due to NAT timing
out, but the afs filesystem doesn't then realise that the directory is not
up to date.
Alleviate this by using one of the status slots to check the directory in
which the lookup is being done.

Make the inode hash table RCU searchable so that searches that want to
access or modify an inode without taking a ref on that inode can do so
without taking the inode hash table lock.
The main thing this requires is some RCU annotation on the list
manipulation operations. Inodes are already freed by RCU in most cases.
Users of this interface must take care as the inode may be still under
construction or may be being torn down around them.
There are at least three instances where this can be of use:
(1) Testing whether the inode number iunique() is going to return is
currently unique (the iunique_lock is still held).
(2) Ext4 date stamp updating.
(3) AFS callback breaking.

Currently when a VSI is built (i.e. reset, set channels, etc.)
the coalesce settings will be preserved in most cases. However, when the
number of q_vectors are increased the settings for the new q_vectors
will be set to the driver defaults of AIM on, Rx/Tx ITR 50, and INTRL 0.
This is causing issues with how the ethtool layer gets the current
coalesce settings since it only uses q_vector 0. So, assume that the user
set the coalesce settings globally (i.e. ethtool -C eth0) and use q_vector
0's settings for all of the new q_vectors.

A VF driver has the ability to request reset via VIRTCHNL_OP_RESET_VF.
This is a required step in VF driver load. Currently, the PF is only
allowing a VF to request reset using this method after the VF has
already communicated resources via VIRTCHNL_OP_GET_VF_RESOURCES.
However, this is incorrect because the VF can request reset before
requesting resources. Fix this by allowing the VF to request a reset
once it has been initialized.

Currently the PF is modifying the VF's port VLAN on the fly when
configured via iproute. This is okay for most cases, but if the VF
already has guest VLANs configured the PF has to remove all of those
filters so only VLAN tagged traffic that matches the port VLAN will
pass. Instead of adding functionality to track which guest VLANs have
been added, just reset the VF each time port VLAN parameters are

Currently the driver does not recognize when there is an 802.1AD VLAN
tag right after the dmac/smac (outermost VLAN tag). If any DCB map is
applied and/or DCB is enabled this is causing the hardware to insert a
VLAN 0 tag after the 802.1AD VLAN tag that is already in the packet.
Fix this by preventing VLAN tag 0 from being added when any VLAN is
already present after dmac/smac (software offloaded) or skb (hardware

Currently a user is not allowed to clear a VF's administratively set MAC
on the PF. Fix this by allowing an all zero MAC address via "ip link set

An example use case for this would be issuing a "virsh shutdown"
command on a VM. The call to iproute mentioned above is part of this flow.
Without this change the driver incorrectly rejects clearing the VF's

If a 6 GHz channel exists, then we can probably safely assume that

This will probably need to be extended to check the interface type

Add some code to obtain and parse the 6 GHz operation field
inside the HE operation element.
While at it, fix the required length using sizeof() the new
struct, which is 5 instead of 4 now.

This allows identifying whether or not a channel is a PSC
(preferred scanning channel).

My previous commit here was wrong, it didn't check the new
flag in two necessary places, so things didn't work. Fix that.

The 6GHz band does not have regulatory approval yet, but things are
moving forward. However, that has led to a change in the channelization
of the 6GHz band which has been accepted in the 11ax specification. It
also fixes a missing MHZ_TO_KHZ() macro for 6GHz channels while at it.
This change is primarily thrown in to discuss how to deal with it.
I noticed ath11k adding 6G support with old channelization and ditto
for iw. It probably involves changes in hostapd as well.

The updates to change to kHz frequencies and the 6 GHz
additions evidently overlapped (or rather, I didn't see
it when applying the latter), so the 6 GHz is broken.
Fix this.
