Since commit:

    048e3a34a2 can: flexcan: poll MCR_LPM_ACK instead of GPR ACK for stop mode acknowledgment

the driver polls the IP core's internal bit MCR[LPM_ACK] as stop mode
acknowledge and not the acknowledgment on chip level.

This means the 4th and 5th value of the property "fsl,stop-mode" isn't used
anymore. This patch removes the used "ack_gpr" and "ack_bit" from the driver.

Add an helper function can_bit_time() which returns the duration (in

Rationale for this patch: the sync segment and the bit time are two
concepts which are defined in the CAN ISO standard. Device drivers for
CAN might need those.

0704c57436 can: m_can_platform: remove unnecessary m_can_class_resume() call

removed the m_can_class_resume() call in the runtime resume path to get
rid of a infinite recursion, so the runtime resume now only handles the device
clocks.

Unfortunately it did not remove the complementary m_can_class_suspend() call in
the runtime suspend function, so those paths are now unbalanced, which causes
the pinctrl state to get stuck on the "sleep" state, which breaks all CAN
functionality on SoCs where this state is defined. Remove the
m_can_class_suspend() call to fix this.

Else, if get_registers() failed instead, a randomly generated MAC

Vladimir Oltean 2e554a7a5d net: dsa: propagate switchdev vlan_filtering prepare phase to drivers
A driver may refuse to enable VLAN filtering for any reason beyond what
the DSA framework cares about, such as:
- having tc-flower rules that rely on the switch being VLAN-aware
- the particular switch does not support VLAN, even if the driver does
  (the DSA framework just checks for the presence of the .port_vlan_add
  and .port_vlan_del pointers)
- simply not supporting this configuration to be toggled at runtime

Currently, when a driver rejects a configuration it cannot support, it
does this from the commit phase, which triggers various warnings in
switchdev.

So propagate the prepare phase to drivers, to give them the ability to
refuse invalid configurations cleanly and avoid the warnings.

Since we need to modify all function prototypes and check for the
prepare phase from within the drivers, take that opportunity and move
the existing driver restrictions within the prepare phase where that is
possible and easy.

1. Keep the code for the normal (non-error) flow at the lowest
indentation level. And use "goto drop" for all error handling.

2. Replace code that pads short Ethernet frames with a "__skb_pad" call.

3. Change "dev_kfree_skb" to "kfree_skb" in error handling code.
"kfree_skb" is the correct function to call when dropping an skb due to
an error. "dev_kfree_skb", which is an alias of "consume_skb", is for
dropping skbs normally (not due to an error).

Thus, when kfree(dst_opts[i]) is called in the second loop in this
order, (i.e., inst_rollback followed by alloc_rollback),
dst_optsp[option_count - 2] is the first element freed, and
dst_opts[option_count - 1] does not get freed, and thus, a memory
leak is caused.

This memory leak can be fixed, by assigning i = option_count (instead of
option_count - 1).

Michael Chan 8d4bd96b54 bnxt_en: Eliminate unnecessary RX resets.
Currently, the driver will schedule RX ring reset when we get a buffer
error in the RX completion record.  These RX buffer errors can be due
to normal out-of-buffer conditions or a permanent error in the RX
ring.  Because the driver cannot distinguish between these 2
conditions, we assume all these buffer errors require reset.

This is very disruptive when it is just a normal out-of-buffer
condition.  Newer firmware will now monitor the rings for the permanent
failure and will send a notification to the driver when it happens.
This allows the driver to reset only when such a notification is
received.  In environments where we have predominently out-of-buffer
conditions, we now can avoid these unnecessary resets.

Michael Chan 1b5c8b63d6 bnxt_en: Reduce unnecessary message log during RX errors.
There is logic in the RX path to detect unexpected handles in the
RX completion.  We'll print a warning and schedule a reset.  The
next expected handle is then set to 0xffff which is guaranteed to
not match any valid handle.  This will force all remaining packets in
the ring to be discarded before the reset.  There can be hundreds of
these packets remaining in the ring and there is no need to print the
warnings for these forced errors.

Michael Chan 8fbf58e17d bnxt_en: Implement RX ring reset in response to buffer errors.
On some older chips, it is necessary to do a reset when we get buffer
errors associated with an RX ring.  These buffer errors may become
frequent if the RX ring underruns under heavy traffic.  The current
code does a global reset of all reasources when this happens.  This
works but creates a big disruption of all rings when one RX ring is
having problem.  This patch implements a localized RX ring reset of
just the RX ring having the issue.  All other rings including all
TX rings will not be affected by this single RX ring reset.

Only the older chips prior to the P5 class supports this reset.
Because it is not a global reset, packets may still be arriving
while we are calling firmware to reset that ring.  We need to be
sure that we don't post any buffers during this time while the
ring is undergoing reset.  After firmware completes successfully,
the ring will be in the reset state with no buffers and we can start
filling it with new buffers and posting them.

Vineetha G. Jaya Kumaran 388e201d41 net: stmmac: Modify configuration method of EEE timers
Ethtool manual stated that the tx-timer is the "the amount of time the
device should stay in idle mode prior to asserting its Tx LPI". The
previous implementation for "ethtool --set-eee tx-timer" sets the LPI TW
timer duration which is not correct. Hence, this patch fixes the
"ethtool --set-eee tx-timer" to configure the EEE LPI timer.

The LPI TW Timer will be using the defined default value instead of
"ethtool --set-eee tx-timer" which follows the EEE LS timer implementation.

Changelog V2
*Not removing/modifying the eee_timer.
*EEE LPI timer can be configured through ethtool and also the eee_timer
module param.
*EEE TW Timer will be configured with default value only, not able to be
configured through ethtool or module param. This follows the implementation
of the EEE LS Timer.

DPAA2 devices do not support controlling the action of independent

Vladimir Oltean 16a7a15f4b net: mscc: ocelot: offload redirect action to VCAP IS2
Via the OCELOT_MASK_MODE_REDIRECT flag put in the IS2 action vector, it
is possible to replace previous forwarding decisions with the port mask
installed in this rule.

I have studied Table 54 "MASK_MODE and PORT_MASK Combinations" from the
VSC7514 documentation and it appears to behave sanely when this rule is
installed in either lookup 0 or 1. Namely, a redirect in lookup 1 will
overwrite the forwarding decision taken by any entry in lookup 0.

Vladimir Oltean f854e6f6f4 net: mscc: ocelot: relax ocelot_exclusive_mac_etype_filter_rules()
The issue which led to the introduction of this check was that MAC_ETYPE
rules, such as filters on dst_mac and src_mac, would only match non-IP
frames. There is a knob in VCAP_S2_CFG which forces all IP frames to be
treated as non-IP, which is what we're currently doing if the user
requested a dst_mac filter, in order to maintain sanity.

But that knob is actually per IS2 lookup. And the good thing with
exposing the lookups to the user via tc chains is that we're now able to
offload MAC_ETYPE keys to one lookup, and IP keys to the other lookup.
So let's do that.

Xiaoliang Yang 75944fda1d net: mscc: ocelot: offload ingress skbedit and vlan actions to VCAP IS1
VCAP IS1 is a VCAP module which can filter on the most common L2/L3/L4
Ethernet keys, and modify the results of the basic QoS classification
and VLAN classification based on those flow keys.

There are 3 VCAP IS1 lookups, mapped over chains 10000, 11000 and 12000.
Currently the driver is hardcoded to use IS1_ACTION_TYPE_NORMAL half
keys.

Note that the VLAN_MANGLE has been omitted for now. In hardware, the
VCAP_IS1_ACT_VID_REPLACE_ENA field replaces the classified VLAN
(metadata associated with the frame) and not the VLAN from the header
itself. There are currently some issues which need to be addressed when
operating in standalone, or in bridge with vlan_filtering=0 modes,
because in those cases the switch ports have VLAN awareness disabled,
and changing the classified VLAN to anything other than the pvid causes
the packets to be dropped. Another issue is that on egress, we expect
port tagging to push the classified VLAN, but port tagging is disabled
in the modes mentioned above, so although the classified VLAN is
replaced, it is not visible in the packet transmitted by the switch.

Vladimir Oltean 1397a2eb52 net: mscc: ocelot: create TCAM skeleton from tc filter chains
For Ocelot switches, there are 2 ingress pipelines for flow offload
rules: VCAP IS1 (Ingress Classification) and IS2 (Security Enforcement).
IS1 and IS2 support different sets of actions. The pipeline order for a
packet on ingress is:

Basic classification -> VCAP IS1 -> VCAP IS2

Furthermore, IS1 is looked up 3 times, and IS2 is looked up twice (each
TCAM entry can be configured to match only on the first lookup, or only
on the second, or on both etc).

Because the TCAMs are completely independent in hardware, and because of
the fixed pipeline, we actually have very limited options when it comes
to offloading complex rules to them while still maintaining the same
semantics with the software data path.

This patch maps flow offload rules to ingress TCAMs according to a
predefined chain index number. There is going to be a script in
selftests that clarifies the usage model.

There is also an egress TCAM (VCAP ES0, the Egress Rewriter), which is
modeled on top of the default chain 0 of the egress qdisc, because it
doesn't have multiple lookups.

Vladimir Oltean 319e4dd11a net: mscc: ocelot: introduce conversion helpers between port and netdev
Since the mscc_ocelot_switch_lib is common between a pure switchdev and
a DSA driver, the procedure of retrieving a net_device for a certain
port index differs, as those are registered by their individual
front-ends.

Up to now that has been dealt with by always passing the port index to
the switch library, but now, we're going to need to work with net_device
pointers from the tc-flower offload, for things like indev, or mirred.
It is not desirable to refactor that, so let's make sure that the flower
offload core has the ability to translate between a net_device and a
port index properly.

Vladimir Oltean ea9d1f30b1 net: mscc: ocelot: offload multiple tc-flower actions in same rule
At this stage, the tc-flower offload of mscc_ocelot can only delegate
rules to the VCAP IS2 security enforcement block. These rules have, in
hardware, separate bits for policing and for overriding the destination
port mask and/or copying to the CPU. So it makes sense that we attempt
to expose some more of that low-level complexity instead of simply
choosing between a single type of action.

Something similar happens with the VCAP IS1 block, where the same action
can contain enable bits for VLAN classification and for QoS
classification at the same time.

So model the action structure after the hardware description, and let
the high-level ocelot_flower.c construct an action vector from multiple
tc actions.

Maor Dickman 2b0219898b net/mlx5e: CT, Fix coverity issue
The cited commit introduced the following coverity issue at function
mlx5_tc_ct_rule_to_tuple_nat:
- Memory - corruptions (OVERRUN)
  Overrunning array "tuple->ip.src_v6.in6_u.u6_addr32" of 4 4-byte
  elements at element index 7 (byte offset 31) using index
  "ip6_offset" (which evaluates to 7).

In case of IPv6 destination address rewrite, ip6_offset values are
between 4 to 7, which will cause memory overrun of array
"tuple->ip.src_v6.in6_u.u6_addr32" to array
"tuple->ip.dst_v6.in6_u.u6_addr32".

Fixed by writing the value directly to array
"tuple->ip.dst_v6.in6_u.u6_addr32" in case ip6_offset values are
between 4 to 7.

Aya Levin c3c9402373 net/mlx5e: Add resiliency in Striding RQ mode for packets larger than MTU
Prior to this fix, in Striding RQ mode the driver was vulnerable when
receiving packets in the range (stride size - headroom, stride size].
Where stride size is calculated by mtu+headroom+tailroom aligned to the
closest power of 2.
Usually, this filtering is performed by the HW, except for a few cases:
- Between 2 VFs over the same PF with different MTUs
- On bluefield, when the host physical function sets a larger MTU than
  the ARM has configured on its representor and uplink representor.

When the HW filtering is not present, packets that are larger than MTU
might be harmful for the RQ's integrity, in the following impacts:
1) Overflow from one WQE to the next, causing a memory corruption that
in most cases is unharmful: as the write happens to the headroom of next
packet, which will be overwritten by build_skb(). In very rare cases,
high stress/load, this is harmful. When the next WQE is not yet reposted
and points to existing SKB head.
2) Each oversize packet overflows to the headroom of the next WQE. On
the last WQE of the WQ, where addresses wrap-around, the address of the
remainder headroom does not belong to the next WQE, but it is out of the
memory region range. This results in a HW CQE error that moves the RQ
into an error state.

Solution:
Add a page buffer at the end of each WQE to absorb the leak. Actually
the maximal overflow size is headroom but since all memory units must be
of the same size, we use page size to comply with UMR WQEs. The increase
in memory consumption is of a single page per RQ. Initialize the mkey
with all MTTs pointing to a default page. When the channels are
activated, UMR WQEs will redirect the RX WQEs to the actual memory from
the RQ's pool, while the overflow MTTs remain mapped to the default page.

Saeed Mahameed b898ce7bcc net/mlx5: cmdif, Avoid skipping reclaim pages if FW is not accessible
In case of pci is offline reclaim_pages_cmd() will still try to call
the FW to release FW pages, cmd_exec() in this case will return a silent
success without actually calling the FW.

This is wrong and will cause page leaks, what we should do is to detect
pci offline or command interface un-available before tying to access the
FW and manually release the FW pages in the driver.

In this patch we share the code to check for FW command interface
availability and we call it in sensitive places e.g. reclaim_pages_cmd().

Alternative fix:
 1. Remove MLX5_CMD_OP_MANAGE_PAGES form mlx5_internal_err_ret_value,
    command success simulation list.
 2. Always Release FW pages even if cmd_exec fails in reclaim_pages_cmd().

Eran Ben Elisha 1d5558b1f0 net/mlx5: poll cmd EQ in case of command timeout
Once driver detects a command interface command timeout, it warns the
user and returns timeout error to the caller. In such case, the entry of
the command is not evacuated (because only real event interrupt is allowed
to clear command interface entry). If the HW event interrupt
of this entry will never arrive, this entry will be left unused forever.
Command interface entries are limited and eventually we can end up without
the ability to post a new command.

In addition, if driver will not consume the EQE of the lost interrupt and
rearm the EQ, no new interrupts will arrive for other commands.

Add a resiliency mechanism for manually polling the command EQ in case of
a command timeout. In case resiliency mechanism will find non-handled EQE,
it will consume it, and the command interface will be fully functional
again. Once the resiliency flow finished, wait another 5 seconds for the
command interface to complete for this command entry.

Define mlx5_cmd_eq_recover() to manage the cmd EQ polling resiliency flow.
Add an async EQ spinlock to avoid races between resiliency flows and real
interrupts that might run simultaneously.

Eran Ben Elisha 50b2412b7e net/mlx5: Avoid possible free of command entry while timeout comp handler
Upon command completion timeout, driver simulates a forced command
completion. In a rare case where real interrupt for that command arrives
simultaneously, it might release the command entry while the forced
handler might still access it.

Fix that by adding an entry refcount, to track current amount of allowed
handlers. Command entry to be released only when this refcount is
decremented to zero.

Command refcount is always initialized to one. For callback commands,
command completion handler is the symmetric flow to decrement it. For
non-callback commands, it is wait_func().

Before ringing the doorbell, increment the refcount for the real completion
handler. Once the real completion handler is called, it will decrement it.

For callback commands, once the delayed work is scheduled, increment the
refcount. Upon callback command completion handler, we will try to cancel
the timeout callback. In case of success, we need to decrement the callback
refcount as it will never run.

In addition, gather the entry index free and the entry free into a one
flow for all command types release.

Eran Ben Elisha 432161ea26 net/mlx5: Fix a race when moving command interface to polling mode
As part of driver unload, it destroys the commands EQ (via FW command).
As the commands EQ is destroyed, FW will not generate EQEs for any command
that driver sends afterwards. Driver should poll for later commands status.

Driver commands mode metadata is updated before the commands EQ is
actually destroyed. This can lead for double completion handle by the
driver (polling and interrupt), if a command is executed and completed by
FW after the mode was changed, but before the EQ was destroyed.

Fix that by using the mlx5_cmd_allowed_opcode mechanism to guarantee
that only DESTROY_EQ command can be executed during this time period.

Xie He 8306266c1d drivers/net/wan/hdlc_fr: Correctly handle special skb->protocol values
The fr_hard_header function is used to prepend the header to skbs before
transmission. It is used in 3 situations:
1) When a control packet is generated internally in this driver;
2) When a user sends an skb on an Ethernet-emulating PVC device;
3) When a user sends an skb on a normal PVC device.

These 3 situations need to be handled differently by fr_hard_header.
Different headers should be prepended to the skb in different situations.

Currently fr_hard_header distinguishes these 3 situations using
skb->protocol. For situation 1 and 2, a special skb->protocol value
will be assigned before calling fr_hard_header, so that it can recognize
these 2 situations. All skb->protocol values other than these special ones
are treated by fr_hard_header as situation 3.

However, it is possible that in situation 3, the user sends an skb with
one of the special skb->protocol values. In this case, fr_hard_header
would incorrectly treat it as situation 1 or 2.

This patch tries to solve this issue by using skb->dev instead of
skb->protocol to distinguish between these 3 situations. For situation
1, skb->dev would be NULL; for situation 2, skb->dev->type would be
ARPHRD_ETHER; and for situation 3, skb->dev->type would be ARPHRD_DLCI.

This way fr_hard_header would be able to distinguish these 3 situations
correctly regardless what skb->protocol value the user tries to use in
situation 3.

Geert Uytterhoeven a6f51f2efa ravb: Add support for explicit internal clock delay configuration
Some EtherAVB variants support internal clock delay configuration, which
can add larger delays than the delays that are typically supported by
the PHY (using an "rgmii-*id" PHY mode, and/or "[rt]xc-skew-ps"
properties).

Historically, the EtherAVB driver configured these delays based on the
"rgmii-*id" PHY mode.  This caused issues with PHY drivers that
implement PHY internal delays properly[1].  Hence a backwards-compatible
workaround was added by masking the PHY mode[2].

Add proper support for explicit configuration of the MAC internal clock
delays using the new "[rt]x-internal-delay-ps" properties.
Fall back to the old handling if none of these properties is present.

Carl Huang 8ec5a6ab9c ath11k: start a timer to update TCL HP
The timer is to check if TCL HP isn't updated to target.
The timer will postpone itself if there are TX operations
during the interval, otherwise the timer handler updates
the HP again so the index value in HP register will be
forwarded to target register, and the timer stops afterwards.

Carl Huang e838c14a9e ath11k: enable shadow register configuration and access
To enable shadow register access, host needs to pass shadow
register configuration to firmware via qmi message. Host also
needs to update ring's HP or TP address to shadow register
address. The write operation to shadow register will be
forwarded to target register by hardware automatically, and
the write operation to shadow register is permitted even
when the target is in power save or sleep mode.

Update the shadow config whenever power up happens.

This feature is controlled by hw parameter supports_shadow_regs which is only
enabled for QCA6390.

Carl Huang a05bd85133 ath11k: read and write registers below unwindowed address
For QCA6390, host can read and write registers below unwindowed
address directly without programming the window register. For
registers below bar0 + 4k - 32, host can read and write regardless
of the power save state. Shadow registers are located below
bar0 + 4K - 32.

Before MHI power up, there is no need to wakeup MHI so ini_done is
added to indicate it.

Carl Huang 089ba909f8 ath11k: debugfs: fix crash during rmmod
With QCA6390 when doing rmmod the kernel crashed. The reason was that the
destroy functions ath11k_debugfs_pdev_destroy() and ath11k_debugfs_soc_destroy()
accidentally had swapped the debugfs directories and
ath11k_debugfs_soc_destroy() was removing an already removed directory, which
crashed the kernel.

The source of confusion is badly named function and variable names. I think the
best way to clean this up is actually to merge the corresponding functions, but
that's for another patch. Let's first just fix the crash.

Carl Huang 6fbd8898b3 ath11k: pci: fix rmmod crash
For QCA6390 we first need to call free_irq() and only then disable_msi(). Otherwise a
kernel BUG below will happen. Also free core, hal_srng and ce resources during
ath11k_pci_remove().

Carl Huang 701e48a43e ath11k: add packet log support for QCA6390
Add packet log support for QCA6390, otherwise the data connection will stall
within a minute or so.  Enable it via debugfs and use trace-cmd to capture the
pktlogs.

echo 0xffff 1 > /sys/kernel/debug/ath11k/qca6390\ hw2.0/mac0/pktlog_filter

The mon status ring doesn't support interrupt so far, so host starts
a timer to reap this ring. The timer handler also reaps the
rxdma_err_dst_ring in case of monitor mode.

As QCA6390 requires bss created ahead of starting vdev, so check
vdev_start_delay for monitor mode.

For QCA6390, it uses wbm_desc_rel_ring to return descriptors.
It also uses rx_refill_buf_ring to fill mon buffer instead of
rxdma_mon_buf_ring.

Kalle Valo 3f6e6c3291 ath11k: disable monitor mode on QCA6390
QCA6390 does not support monitor mode at the moment so disable it altogether,
using a hack as mac80211 does not support disabling it otherwise. Add a boolean
to hw_params to know if hardware supports monitor mode.

IPQ8074 continues to support monitor mode normally.

There are different versions of QCA6390. Check TCSR_SOC_HW_VERSION to make sure
that the device is hw2.0, all the rest are unsupported.

This needs to be checked after ath11k_pci_claim() so move the whole switch choosing hw_ver.

Kalle Valo 2626c26970 ath11k: add interface_modes to hw_params
As QCA6390 does not support mesh interfaces, move the interface_modes to
hw_params. Also create interface combinations dynamically so that it's easy to
change the values.

Now QCA6390 does not claim to support mesh interfaces to user space, but
IPQ8074 continues to do that.

For QCA6390, station vdev needs to delay startup but not for AP mode. On AP
mode vdev starts up immediately after bss peer is created in chanctx assignment
context.

This patch does not affect IPQ8074 family of devices.

The QCA6390 board I have, model 8291M-PR comes with an ELF board file.  To get
this to at least somewhat work, I renamed bdwlan.e04 to 'board.bin' and then
added this patch to check for ELF magic string in the beginning of the file.
If that is found, use type ELF.  After this the driver loads.

Avraham Stern 3ac13d56ec iwlwifi: mvm: ignore the scan duration parameter
The scan request may specify the request scan dwell time.
However, this value may not always be optimal (e.g. short dwell
time for a passive channel). This may happen in a scan request
as a result of beacon report request, in which the AP may request
an active scan, thus setting a short dwell time, but the station
will perform a passive scan due to regulatory.

Ignore the scan duration parameter and always use the internal
scan dwell time which should be optimal.

The overcome instabilities in the RTT results add smoothing logic
to the reported results. In short, the smoothing logic tracks the
RTT average of each responder for a period of time, and in case
a new RTT results is found to be a spur, the tracked RTT average
is reported instead of the current RTT measurement.

Smooth logic debug configuration using iwl-dbg-cfg.ini:

- MVM_FTM_INITIATOR_ENABLE_SMOOTH: Set to 1 to enable smoothing logic
 (default=0).
- MVM_FTM_INITIATOR_SMOOTH_ALPHA: A value between 0 - 100, defining
  the weight of the current RTT results vs. the RTT average tracked
  based on the previous results. A value of 100 means use only the
  current RTT results.
- MVM_FTM_INITIATOR_SMOOTH_AGE_SEC: The maximal time in seconds in which
  the RTT average tracked based on previous results is considered valid.
- MVM_FTM_INITIATOR_SMOOTH_UNDERSHOOT: if the current RTT is positive
  and below the RTT average by at least this value, report the average
  RTT instead of the current one. In units of picoseconds.
- MVM_FTM_INITIATOR_SMOOTH_OVERSHOOT: if the current RTT is positive
  and above the RTT average by at least this value, report the average

Luca Coelho dd2a1256e6 iwlwifi: acpi: rename geo structs to contain versioning
Add the version number to the iwl_geo_tx_power_profile_cmd structs and
move the union into a common place.  Additionally, reuse the code that
sets elements that are at the same place in the struct across
different versions.

While at it remove an unused variable, add a comment and move the v2
specific element setting to inside the if statement.  Additionally,
invert the if for slightly more readability.

Naftali Goldstein 2b3eb12234 iwlwifi: mvm: process ba-notifications also when sta rcu is invalid
The the driver prevents new Tx from being sent during the remove-station
flow is by invalidating the fw_id_to_mac_id rcu of that station.

However, if there was any Tx still in-flight (tx-cmd was sent but the
ba-notif wasn't received yet) the ba-response to those frames is simply
ignored without actually reclaiming anything. This later causes the
driver to think that that some of the station's queues aren't empty when
in practice they are which causes errors in the station remove flow.

Fix this by performing the tx-reclaim also if the rcu is invalid. any DB
that can't be updated due to this is not very important at this stage
since the station is about to be removed soon anyways.
