sparx5_phylink_validate() no longer needs to check for
PHY_INTERFACE_MODE_NA as phylink will walk the supported interface
types to discover the link mode capabilities. Neither is it necessary
to check the device capabilities as we will not be called for
unsupported interface modes. Remove these checks.

When calling setattr_prepare() to determine the validity of the attributes the
ia_{g,u}id fields contain the value that will be written to inode->i_{g,u}id.
When the {g,u}id attribute of the file isn't altered and the caller's fs{g,u}id
matches the current {g,u}id attribute the attribute change is allowed.
The value in ia_{g,u}id does already account for idmapped mounts and will have
taken the relevant idmapping into account. So in order to verify that the
{g,u}id attribute isn't changed we simple need to compare the ia_{g,u}id value
against the inode's i_{g,u}id value.
This only has any meaning for idmapped mounts as idmapping helpers are
idempotent without them. And for idmapped mounts this really only has a meaning
when circular idmappings are used, i.e. mappings where e.g. id 1000 is mapped
to id 1001 and id 1001 is mapped to id 1000. Such ciruclar mappings can e.g. be
useful when sharing the same home directory between multiple users at the same
time.
As an example consider a directory with two files: /source/file1 owned by
{g,u}id 1000 and /source/file2 owned by {g,u}id 1001. Assume we create an
idmapped mount at /target with an idmapping that maps files owned by {g,u}id
1000 to being owned by {g,u}id 1001 and files owned by {g,u}id 1001 to being
owned by {g,u}id 1000. In effect, the idmapped mount at /target switches the
ownership of /source/file1 and source/file2, i.e. /target/file1 will be owned
by {g,u}id 1001 and /target/file2 will be owned by {g,u}id 1000.
This means that a user with fs{g,u}id 1000 must be allowed to setattr
/target/file2 from {g,u}id 1000 to {g,u}id 1000. Similar, a user with fs{g,u}id
1001 must be allowed to setattr /target/file1 from {g,u}id 1001 to {g,u}id
1001. Conversely, a user with fs{g,u}id 1000 must fail to setattr /target/file1
from {g,u}id 1001 to {g,u}id 1000. And a user with fs{g,u}id 1001 must fail to
setattr /target/file2 from {g,u}id 1000 to {g,u}id 1000. Both cases must fail
with EPERM for non-capable callers.
Before this patch we could end up denying legitimate attribute changes and
allowing invalid attribute changes when circular mappings are used. To even get
into this situation the caller must've been privileged both to create that
mapping and to create that idmapped mount.
This hasn't been seen in the wild anywhere but came up when expanding the
testsuite during work on a series of hardening patches. All idmapped fstests
pass without any regressions and we add new tests to verify the behavior of
circular mappings.

The ath11k driver is caching the information about RSN/WPA IE in the
configured beacon template. The cached information is used during
associations to figure out whether 4-way PKT/2-way GTK peer flags need to
be set or not.
But the code never cleared the state when no such IE was found. This can
for example happen when moving from an WPA/RSN to an open setup. The
(seemingly connected) peer was then not able to communicate over the
link because the firmware assumed a different (encryption enabled) state
for the peer.

Whenever the MAC detects a color collision, or any of
its associated stations detects one, the firmware will
send out an event. Add the code to parse and handle
this event and pass the data up to mac80211.
The firmware does not provide an offload feature such
as the one used for CSA. The color change process is
hence triggered via the beacon offload tx completion
events sent out by firmware.
BSS color feature is enabled depending on service flag
advertised by firmware, based on which color change
functionality is invoked.

Currently ath11k only support string type with bus, chip id and board id
such as "bus=ahb,qmi-chip-id=1,qmi-board-id=4" for ahb bus chip and
"bus=pci,qmi-chip-id=0,qmi-board-id=255" for PCIe bus chip in
board-2.bin. For WCN6855, it is not enough to distinguish all different
chips.
This is to add a new string type which include bus, chip id, board id,
vendor, device, subsystem-vendor and subsystem-device for WCN6855.
ath11k will first load board-2.bin and search in it for the board data
with the above parameters, if matched one board data, then download it
to firmware, if not matched any one, then ath11k will download the file
board.bin to firmware.

Commit 31582373a4a8 ("ath11k: Change number of TCL rings to one for
QCA6390") avoids initializing the other entries of dp->tx_ring cause
the corresponding TX rings on QCA6390/WCN6855 are not used, but leaves
those ring masks in ath11k_hw_ring_mask_qca6390.tx unchanged. Normally
this is OK because we will only get interrupts from the first TX ring
on these chips and thus only the first entry of dp->tx_ring is involved.
In case of one MSI vector, all DP rings share the same IRQ. For each
interrupt, all rings have to be checked, which means the other entries
of dp->tx_ring are involved. However since they are not initialized,
system crashes.
Fix this issue by simply removing those ring masks.

The DMA buffers of dbring which is used for spectral/cfr
starts at certain offset from original kmalloc() returned buffer.
This is not cache line aligned.
And also driver tries to access the data that is immediately before
this offset address (i.e. buff->paddr) after doing dma map.
This will cause cache line sharing issues and data corruption,
if CPU happen to write back cache after HW has dma'ed the data.
Fix this by mapping a cache line aligned buffer to dma.

Firmware credit flow control is enabled for WMI control services,
which expects available tokens should be acquired before sending a
command to the target. Also the token gets released when firmware
receives the command.
This credit-based flow limits driver to send WMI command only
when the token available which is causing WMI commands to timeout and
return -EAGAIN, whereas firmware has enough capability to process the
WMI command. To fix this Tx starvation issue, introduce the ability to
disable the credit flow for the WMI path.
The driver sends WMI configuration for disabling credit flow to firmware
by two ways.
1. By using a global flag
(HTC_MSG_SETUP_COMPLETE_EX_ID msg type flags)
2. By using a local flag
(ATH11K_HTC_CONN_FLAGS_DISABLE_CREDIT_FLOW_CTRL = 1 << 3)
Ath11k uses both these configurations to disable credit flow for the
WMI path completely.
Also added a hw_param member for credit flow control by which we can
enable or disable it based on per-target basis. Currently we are disabling
credit flow for IPQ8074, IPQ6018, and QCN9074 as recommended by firmware.

Some ETSI countries have a small overlap in the wireless-regdb with an ETSI
channel (5590-5650). A good example is Australia:
country AU: DFS-ETSI
(2400 - 2483.5 @ 40), (36)
(5150 - 5250 @ 80), (23), NO-OUTDOOR, AUTO-BW
(5250 - 5350 @ 80), (20), NO-OUTDOOR, AUTO-BW, DFS
(5470 - 5600 @ 80), (27), DFS
(5650 - 5730 @ 80), (27), DFS
(5730 - 5850 @ 80), (36)
(57000 - 66000 @ 2160), (43), NO-OUTDOOR
If the firmware (or the BDF) is shipped with these rules then there is only
a 10 MHz overlap with the weather radar:
* below: 5470 - 5590
* weather radar: 5590 - 5600
* above: (none for the rule "5470 - 5600 @ 80")
There are several wrong assumption in the ath11k code:
* there is always a valid range below the weather radar
(actually: there could be no range below the weather radar range OR range
could be smaller than 20 MHz)
* intersected range in the weather radar range is valid
(actually: the range could be smaller than 20 MHz)
* range above weather radar is either empty or valid
(actually: the range could be smaller than 20 MHz)
These wrong assumption will lead in this example to a rule
(5590 - 5600 @ 20), (N/A, 27), (600000 ms), DFS, AUTO-BW
which is invalid according to is_valid_reg_rule() because the freq_diff is
only 10 MHz but the max_bandwidth is set to 20 MHz. Which results in a
rejection like:

ath11k c000000.wifi: failed to perform regd update : -22
Invalid regulatory domain detected
To avoid this, the algorithm has to be changed slightly. Instead of
splitting a rule which overlaps with the weather radar range into 3 pieces
and accepting the first two parts blindly, it must actually be checked for
each piece whether it is a valid range. And only if it is valid, add it to
the output array.
When these checks are in place, the processed rules for AU would end up as
country AU: DFS-ETSI

Don't create eswitch QoS (root TSAR) on switch mode change. Create it on
first child TSAR object creation - vport or rate group. Keep track
root TSAR references and release root TSAR with last object deletion.
No need to check for QoS is enabled when installing tc matchall filter.
Remove related helper function due to no users of it.

Vports' QoS is not commonly used but consume SW/HW resources, which
becomes an issue on BlueField SoC systems.
Don't enable QoS on vports by default on eswitch mode change and enable
when it's going to be used by one of the top level users:
- configuring TC matchall filter with police action;
- setting rate with legacy NDO API;
- calling devlink ops->rate_leaf_*() callbacks.
Disable vport QoS on vport cleanup.

An eswitch vport of the devlink port is always enabled before a
devlink port is registered. And a eswitch vport is always disabled
after a devlink port is unregistered.
Hence avoid the vport enabled check in the devlink callback routine.
Such check is only applicable in the legacy SR-IOV callbacks.

There is a use case that the local and remote VTEPs are in the same
host. Currently, the out ifindex is not specified when looking up the
decap route for offloads. So in this case, a local route is returned
and the route dev is lo.
Actual tunnel interface can be created with a parameter "dev" [1],
which specifies the physical device to use for tunnel endpoint
communication. Pass this parameter to driver when looking up decap
route for offloads. So that a unicast route will be returned.

The recent addition of timestamp correction to compensate the CDC error
introduced a subtle signed/unsigned bug in stmmac_get_tx_hwtstamp() while
it managed for some obscure reason to avoid that in stmmac_get_rx_hwtstamp().
The issue is:
s64 adjust = 0;
u64 ns;
adjust += -(2 * (NSEC_PER_SEC / priv->plat->clk_ptp_rate));
ns += adjust;
works by chance on 64bit, but falls apart on 32bit because the compiler
knows that adjust fits into 32bit and then treats the addition as a u64 +
u32 resulting in an off by ~2 seconds failure.
The RX variant uses an u64 for adjust and does the adjustment via
ns -= adjust;
because consistency is obviously overrated.
Get rid of the pointless zero initialized adjust variable and do:
ns -= (2 * NSEC_PER_SEC) / priv->plat->clk_ptp_rate;
which is obviously correct and spares the adjust obfuscation. Aside of that
it yields a more accurate result because the multiplication takes place
before the integer divide truncation and not afterwards.
Stick the calculation into an inline so it can't be accidentally
disimproved. Return an u32 from that inline as the result is guaranteed
to fit which lets the compiler optimize the substraction.

Without dropping dst, the packets sent from local mirred/redirected
to ingress will may still use the old dst. ip_rcv() will drop it as
the old dst is for output and its .input is dst_discard.
This patch is to fix by also dropping dst for those packets that are
mirred or redirected from egress to ingress in act_mirred.
Note that we don't drop it for the direction change from ingress to
egress, as on which there might be a user case attaching a metadata
dst by act_tunnel_key that would be used later.

When the amt module is being removed, it calls cancel_delayed_work()
to cancel pending delayed_work. But this function doesn't wait for
canceling delayed_work.
So, workers can be still doing after module delete.
In order to avoid this, cancel_delayed_work_sync() should be used instead.

With newer chip versions ASPM-related issues seem to occur only if
L1.2 is enabled. I have a test system with RTL8168h that gives a
number of rx_missed errors when running iperf and L1.2 is enabled.
With L1.2 disabled (and L1 + L1.1 active) everything is fine.
See also [0]. Can't test this, but L1 + L1.1 being active should be
sufficient to reach higher package power saving states.
