Wen Yang d2c50b1cd9 net: mscc: ocelot: add missing of_node_put after calling of_get_child_by_name
of_node_put needs to be called when the device node which is got
from of_get_child_by_name finished using.
In both cases of success and failure, we need to release 'ports',
so clean up the code using goto.

Florian Westphal 895b5c9f20 netfilter: drop bridge nf reset from nf_reset
commit 174e23810c
("sk_buff: drop all skb extensions on free and skb scrubbing") made napi
recycle always drop skb extensions.  The additional skb_ext_del() that is
performed via nf_reset on napi skb recycle is not needed anymore.

Most nf_reset() calls in the stack are there so queued skb won't block
'rmmod nf_conntrack' indefinitely.

This removes the skb_ext_del from nf_reset, and renames it to a more
fitting nf_reset_ct().

In a few selected places, add a call to skb_ext_reset to make sure that
no active extensions remain.

I am submitting this for "net", because we're still early in the release
cycle.  The patch applies to net-next too, but I think the rename causes
needless divergence between those trees.

Background: the switch only offers partial RX timestamps (24 bits) and
it is up to the driver to read the PTP clock to fill those timestamps up
to 64 bits. But the PTP clock readout needs to happen quickly enough (in
0.135 seconds, in fact), otherwise the PTP clock will wrap around 24
bits, condition which cannot be detected.

Looking at the 'max 134217731' value on output line 3, one can see that
in hex it is 0x8000003. Because the PTP clock resolution is 8 ns,
that means 0x1000000 in ticks, which is exactly 2^24. So indeed this is
a PTP clock wraparound, but the reason might be surprising.

What is going on is that sja1105_tstamp_reconstruct(priv, now, ts)
expects a "now" time that is later than the "ts" was snapshotted at.
This, of course, is obvious: we read the PTP time _after_ the partial RX
timestamp was received. However, the workqueue is processing frames from
a skb queue and reuses the same PTP time, read once at the beginning.
Normally the skb queue only contains one frame and all goes well. But
when the skb queue contains two frames, the second frame that gets
dequeued might have been partially timestamped by the RX MAC _after_ we
had read our PTP time initially.

The code was originally like that due to concerns that SPI access for
PTP time readout is a slow process, and we are time-constrained anyway
(aka: premature optimization). But some timing analysis reveals that the
time spent until the RX timestamp is completely reconstructed is 1 order
of magnitude lower than the 0.135 s deadline even under worst-case
conditions. So we can afford to read the PTP time for each frame in the
RX timestamping queue, which of course ensures that the full PTP time is
in the partial timestamp's future.

Ido Schimmel 979b9b251a mlxsw: spectrum: Clear VLAN filters during port initialization
When a port is created, its VLAN filters are not cleared by the
firmware. This causes tagged packets to be later dropped by the ingress
STP filters, which default to DISCARD state.

The above did not matter much until commit b5ce611fd9 ("mlxsw:
spectrum: Add devlink-trap support") where we exposed the drop reason to
users.

Without this patch, the drop reason users will see is not consistent. If
a port is enslaved to a VLAN-aware bridge and a packet with an invalid
VLAN tries to ingress the bridge, it will be dropped due to ingress STP
filter. If the VLAN is later enabled and then disabled, the packet will
be dropped by the ingress VLAN filter despite the above being a
seemingly NOP operation.

Fix this by clearing all the VLAN filters during port initialization.
Adjust the test accordingly.

However, for 16/32/64bit registers, the stride is 2/4/8 respectively. This

The size of individual pages in the page pool in given by an order. The
order is the binary logarithm of the number of pages that make up one of
the pages in the pool. However, the driver currently passes the number
of pages rather than the order, so it ends up wasting quite a bit of
memory.

Fix this by taking the binary logarithm and passing that in the order
field.

Xin Long ba56d8ce38 macsec: drop skb sk before calling gro_cells_receive
Fei Liu reported a crash when doing netperf on a topo of macsec
dev over veth:

  [  449.136088]  __do_softirq+0x128/0x320

The issue was caused by skb's true_size changed without its sk's
sk_wmem_alloc increased in tcp/skb_gro_receive(). Later when the
skb is being freed and the skb's truesize is subtracted from its
sk's sk_wmem_alloc in tcp_wfree(), underflow occurs.

macsec is calling gro_cells_receive() to receive a packet, which
actually requires skb->sk to be NULL. However when macsec dev is
over veth, it's possible the skb->sk is still set if the skb was
not unshared or expanded from the peer veth.

ip_rcv() is calling skb_orphan() to drop the skb's sk for tproxy,
but it is too late for macsec's calling gro_cells_receive(). So
fix it by dropping the skb's sk earlier on rx path of macsec.

Juliet Kim b27507bb59 net/ibmvnic: unlock rtnl_lock in reset so linkwatch_event can run
Commit a5681e20b5 ("net/ibmnvic: Fix deadlock problem in reset")
made the change to hold the RTNL lock during a reset to avoid deadlock
but linkwatch_event is fired during the reset and needs the RTNL lock.
That keeps linkwatch_event process from proceeding until the reset
is complete. The reset process cannot tolerate the linkwatch_event
processing after reset completes, so release the RTNL lock during the
process to allow a chance for linkwatch_event to run during reset.
This does not guarantee that the linkwatch_event will be processed as
soon as link state changes, but is an improvement over the current code
where linkwatch_event processing is always delayed, which prevents
transmissions on the device from being deactivated leading transmit
watchdog timer to time-out.

Release the RTNL lock before link state change and re-acquire after
the link state change to allow linkwatch_event to grab the RTNL lock
and run during the reset.

Dmytro Linkin fe1587a7de net/mlx5e: Fix matching on tunnel addresses type
In mlx5 parse_tunnel_attr() function dispatch on encap IP address type
is performed by directly checking flow_rule_match_key() on
FLOW_DISSECTOR_KEY_ENC_IPV4_ADDRS, and then on
FLOW_DISSECTOR_KEY_ENC_IPV6_ADDRS. However, since those are stored in
union, first check is always true if any type of encap address is set,
which leads to IPv6 tunnel encap address being parsed as IPv4 by mlx5.

Saeed Mahameed d22fcc806b net/mlx5e: Fix traffic duplication in ethtool steering
Before this patch, when adding multiple ethtool steering rules with
identical classification, the driver used to append the new destination
to the already existing hw rule, which caused the hw to forward the
traffic to all destinations (rx queues).

Here we avoid this by setting the "no append" mlx5 fs core flag when
adding a new ethtool rule.

Yan-Hsuan Chuang 0b8dc6abbd rtw88: configure firmware after HCI started
After firmware has been downloaded, driver should send
some information to it through H2C commands. Those H2C
commands are transmitted through TX path.

But before HCI has been started, the TX path is not
working completely. Such as PCI interfaces, the interrupts
are not enabled, hence TX interrupts will not be issued
after H2C skb has been DMAed to the device. And the H2C
skbs will not be released until the device is powered off.

As the object is the trivial empty case, change the called function
to accept a NULL pointer to mean the same thing and remove the
large variable in the two callers.

Yan-Hsuan Chuang 0e41edcdfe rtw88: pci: release tx skbs DMAed when stop
Interrupt is disabled to stop PCI, which means the skbs
queued for each TX ring will not be released via DMA
interrupt. To avoid those skbs remained being left in
the skb queue until PCI has been removed, driver needs
to release skbs by itself.

Murilo Fossa Vicentini dd0f9d896d ibmvnic: Warn unknown speed message only when carrier is present
With commit 0655f9943d ("net/ibmvnic: Update carrier state after link
state change") we are now able to detect when the carrier is properly
present in the device, so only report an unexpected unknown speed when it
is properly detected. Unknown speed is expected to be seen by the device
in case the backing device has no link detected.

by making that function available, but do almost nothing but

While at it, also fix that function itself to not error out

just send the empty firmware command in this case as well.

Merge tag 'leds-for-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds

Pull LED updates from Jacek Anaszewski:
 "In this cycle we've finally managed to contribute the patch set
  sorting out LED naming issues. Besides that there are many changes
  scattered among various LED class drivers and triggers.

  LED naming related improvements:

   - add new 'function' and 'color' fwnode properties and deprecate
     'label' property which has been frequently abused for conveying
     vendor specific names that have been available in sysfs anyway

   - introduce a set of standard LED_FUNCTION* definitions

   - introduce a set of standard LED_COLOR_ID* definitions

   - add a new {devm_}led_classdev_register_ext() API with the
     capability of automatic LED name composition basing on the
     properties available in the passed fwnode; the function is
     backwards compatible in a sense that it uses 'label' data, if
     present in the fwnode, for creating LED name

   - add tools/leds/get_led_device_info.sh script for retrieving LED
     vendor, product and bus names, if applicable; it also performs
     basic validation of an LED name

   - update following drivers and their DT bindings to use the new LED
     registration API:

        - leds-an30259a, leds-gpio, leds-as3645a, leds-aat1290, leds-cr0014114,
          leds-lm3601x, leds-lm3692x, leds-lp8860, leds-lt3593, leds-sc27xx-blt

  Other LED class improvements:

   - replace {devm_}led_classdev_register() macros with inlines

   - allow to call led_classdev_unregister() unconditionally

   - switch to use fwnode instead of be stuck with OF one

  LED triggers improvements:

   - led-triggers:
        - fix dereferencing of null pointer
        - fix a memory leak bug

   - ledtrig-gpio:
        - GPIO 0 is valid

  Drop superseeded apu2/3 support from leds-apu since for apu2+ a newer,
  more complete driver exists, based on a generic driver for the AMD
  SOCs gpio-controller, supporting LEDs as well other devices:

   - drop profile field from priv data

   - drop iosize field from priv data

   - drop enum_apu_led_platform_types

   - drop superseeded apu2/3 led support

   - add pr_fmt prefix for better log output

   - fix error message on probing failure

  Other misc fixes and improvements to existing LED class drivers:

   - leds-ns2, leds-max77650:
        - add of_node_put() before return

   - leds-pwm, leds-is31fl32xx:
        - use struct_size() helper

   - leds-lm3697, leds-lm36274, leds-lm3532:
        - switch to use fwnode_property_count_uXX()

   - leds-lm3532:
        - fix brightness control for i2c mode
        - change the define for the fs current register
        - fixes for the driver for stability
        - add full scale current configuration
        - dt: Add property for full scale current.
        - avoid potentially unpaired regulator calls
        - move static keyword to the front of declarations
        - fix optional led-max-microamp prop error handling

   - leds-max77650:
        - add of_node_put() before return
        - add MODULE_ALIAS()
        - Switch to fwnode property API

   - leds-as3645a:
        - fix misuse of strlcpy

   - leds-netxbig:
        - add of_node_put() in netxbig_leds_get_of_pdata()
        - remove legacy board-file support

   - leds-is31fl319x:
        - simplify getting the adapter of a client

   - leds-ti-lmu-common:
        - fix coccinelle issue
        - move static keyword to the front of declaration

   - leds-syscon:
        - use resource managed variant of device register

   - leds-ktd2692:
        - fix a typo in the name of a constant

   - leds-lp5562:
        - allow firmware files up to the maximum length

   - leds-an30259a:
        - fix typo

   - leds-pca953x:
        - include the right header"

 platforms based on the XScale and ARM9 CPU cores, which are between 10
 and 20 years old.
 
 The Kendin/Micrel/Microchip KS8695, Winbond/Nuvoton W90x900 and Intel
 IOP33x/IOP13xx platforms are removed after we determined that nobody is
 using them any more.
 
 The TI Davinci and NXP LPC32xx platforms on the other hand are still in
 active use and are converted to the ARCH_MULTIPLATFORM build, meaning
 that we can compile a kernel that works on these along with most other
 ARMv5 platforms. Changes toward that goal are also merged for IOP32x,
 but additional work is needed to complete this. Patches for the
 remaining ARMv5 platforms have started but need more work and some
 testing.
 
 Support for the new ASpeed AST2600 gets added, this is based on the
 Cortex-A7 ARMv7 core, and is a newer version of the existing ARMv5 and
 ARMv6 chips in the same family.
 
 Other changes include a cleanup of the ST-Ericsson ux500 platform
 and the move of the TI Davinci platform to a new clocksource driver.

ena_dev->intr_moder_rx/tx_interval save the intervals received from the
user after dividing them by ena_dev->intr_delay_resolution. Therefore
when intr_delay_resolution changes, the code needs to first mutiply
intr_moder_rx/tx_interval by the previous intr_delay_resolution to get
the value originally given by the user, and only then divide it by the
new intr_delay_resolution.

Current code does not first multiply intr_moder_rx/tx_interval by the old
intr_delay_resolution. This commit fixes it.

Alexandru Ardelean 65d7be094f net: phy: adin: implement Energy Detect Powerdown mode via phy-tunable
This driver becomes the first user of the kernel's `ETHTOOL_PHY_EDPD`
phy-tunable feature.
EDPD is also enabled by default on PHY config_init, but can be disabled via
the phy-tunable control.

When enabling EDPD, it's also a good idea (for the ADIN PHYs) to enable TX
periodic pulses, so that in case the other PHY is also on EDPD mode, there
is no lock-up situation where both sides are waiting for the other to
transmit.

Via the phy-tunable control, TX pulses can be disabled if specifying 0
`tx-interval` via ethtool.

The ADIN PHY supports only fixed 1 second intervals; they cannot be
configured. That is why the acceptable values are 1,
ETHTOOL_PHY_EDPD_DFLT_TX_MSECS and ETHTOOL_PHY_EDPD_NO_TX (which disables
TX pulses).

Dongli Zhang 00b368502d xen-netfront: do not assume sk_buff_head list is empty in error handling
When skb_shinfo(skb) is not able to cache extra fragment (that is,
skb_shinfo(skb)->nr_frags >= MAX_SKB_FRAGS), xennet_fill_frags() assumes
the sk_buff_head list is already empty. As a result, cons is increased only
by 1 and returns to error handling path in xennet_poll().

However, if the sk_buff_head list is not empty, queue->rx.rsp_cons may be
set incorrectly. That is, queue->rx.rsp_cons would point to the rx ring
buffer entries whose queue->rx_skbs[i] and queue->grant_rx_ref[i] are
already cleared to NULL. This leads to NULL pointer access in the next
iteration to process rx ring buffer entries.

Below is how xennet_poll() does error handling. All remaining entries in
tmpq are accounted to queue->rx.rsp_cons without assuming how many
outstanding skbs are remained in the list.

 985 static int xennet_poll(struct napi_struct *napi, int budget)
... ...
1032           if (unlikely(xennet_set_skb_gso(skb, gso))) {
1033                   __skb_queue_head(&tmpq, skb);
1034                   queue->rx.rsp_cons += skb_queue_len(&tmpq);
1035                   goto err;
1036           }

It is better to always have the error handling in the same way.

Sameeh Jubran a53651ec93 net: ena: don't wake up tx queue when down
There is a race condition that can occur when calling ena_down().
The ena_clean_tx_irq() - which is a part of the napi handler -
function might wake up the tx queue when the queue is supposed
to be down (during recovery or changing the size of the queues
for example) This causes the ena_start_xmit() function to trigger
and possibly try to access the destroyed queues.

The race is illustrated below:

Flow A:                                       Flow B(napi handler)
ena_down()
   netif_carrier_off()
   netif_tx_disable()
                                                      ena_clean_tx_irq()
                                                         netif_tx_wake_queue()
   ena_napi_disable_all()
   ena_destroy_all_io_queues()

After these flows the tx queue is active and ena_start_xmit() accesses
the destroyed queue which leads to a kernel panic.

Vladimir Oltean 317ab5b86c net: dsa: sja1105: Configure the Time-Aware Scheduler via tc-taprio offload
This qdisc offload is the closest thing to what the SJA1105 supports in
hardware for time-based egress shaping. The switch core really is built
around SAE AS6802/TTEthernet (a TTTech standard) but can be made to
operate similarly to IEEE 802.1Qbv with some constraints:

- The gate control list is a global list for all ports. There are 8
  execution threads that iterate through this global list in parallel.
  I don't know why 8, there are only 4 front-panel ports.

- Care must be taken by the user to make sure that two execution threads
  never get to execute a GCL entry simultaneously. I created a O(n^4)
  checker for this hardware limitation, prior to accepting a taprio
  offload configuration as valid.

- The spec says that if a GCL entry's interval is shorter than the frame
  length, you shouldn't send it (and end up in head-of-line blocking).
  Well, this switch does anyway.

- The switch has no concept of ADMIN and OPER configurations. Because
  it's so simple, the TAS settings are loaded through the static config
  tables interface, so there isn't even place for any discussion about
  'graceful switchover between ADMIN and OPER'. You just reset the
  switch and upload a new OPER config.

- The switch accepts multiple time sources for the gate events. Right
  now I am using the standalone clock source as opposed to PTP. So the
  base time parameter doesn't really do much. Support for the PTP clock
  source will be added in a future series.

Vladimir Oltean 5f06c63bd3 net: dsa: sja1105: Advertise the 8 TX queues
This is a preparation patch for the tc-taprio offload (and potentially
for other future offloads such as tc-mqprio).

Instead of looking directly at skb->priority during xmit, let's get the
netdev queue and the queue-to-traffic-class mapping, and put the
resulting traffic class into the dsa_8021q PCP field. The switch is
configured with a 1-to-1 PCP-to-ingress-queue-to-egress-queue mapping
(see vlan_pmap in sja1105_main.c), so the effect is that we can inject
into a front-panel's egress traffic class through VLAN tagging from
Linux, completely transparently.

Unfortunately the switch doesn't look at the VLAN PCP in the case of
management traffic to/from the CPU (link-local frames at
01-80-C2-xx-xx-xx or 01-1B-19-xx-xx-xx) so we can't alter the
transmission queue of this type of traffic on a frame-by-frame basis. It
is only selected through the "hostprio" setting which ATM is harcoded in
the driver to 7.

Ciara Loftus 2e78fc620f ixgbe: fix xdp handle calculations
Commit 7cbbf9f1fa ("ixgbe: fix xdp handle calculations") reintroduced
the addition of the umem headroom to the xdp handle in the ixgbe_zca_free,
ixgbe_alloc_buffer_slow_zc and ixgbe_alloc_buffer_zc functions. However,
the headroom is already added to the handle in the function
ixgbe_run_xdp_zc. This commit removes the latter addition and fixes the
case where the headroom is non-zero.

Alexandru Ardelean 5f109d45a4 net: stmmac: socfpga: re-use the `interface` parameter from platform data
The socfpga sub-driver defines an `interface` field in the `socfpga_dwmac`
struct and parses it on init.

The shared `stmmac_probe_config_dt()` function also parses this from the
device-tree and makes it available on the returned `plat_data` (which is
the same data available via `netdev_priv()`).

All that's needed now is to dig that information out, via some
`dev_get_drvdata()` && `netdev_priv()` calls and re-use it.

Using static analysis, I discovered that the "dpriv->pci_priv->pdev"

during probe and is essential for the driver to work.  It would be easy
to add a "ppriv->pdev = pdev;" to dscc4_found1() but this driver has
been broken since before we started using git and no one has complained
so probably we should just remove it.

Bjørn Mork 4d7ffcf3bf cdc_ether: fix rndis support for Mediatek based smartphones
A Mediatek based smartphone owner reports problems with USB
tethering in Linux.  The verbose USB listing shows a rndis_host
interface pair (e0/01/03 + 10/00/00), but the driver fails to
bind with

[  355.960428] usb 1-4: bad CDC descriptors

The problem is a failsafe test intended to filter out ACM serial
functions using the same 02/02/ff class/subclass/protocol as RNDIS.
The serial functions are recognized by their non-zero bmCapabilities.

No RNDIS function with non-zero bmCapabilities were known at the time
this failsafe was added. But it turns out that some Wireless class
RNDIS functions are using the bmCapabilities field. These functions
are uniquely identified as RNDIS by their class/subclass/protocol, so
the failing test can safely be disabled.  The same applies to the two
types of Misc class RNDIS functions.

Applying the failsafe to Communication class functions only retains
the original functionality, and fixes the problem for the Mediatek based
smartphone.

Tow examples of CDC functional descriptors with non-zero bmCapabilities
from Wireless class RNDIS functions are:

0e8d:000a  Mediatek Crosscall Spider X5 3G Phone

      CDC Header:
        bcdCDC               1.10
      CDC ACM:
        bmCapabilities       0x0f
          connection notifications
          sends break
          line coding and serial state
          get/set/clear comm features
      CDC Union:
        bMasterInterface        0
        bSlaveInterface         1
      CDC Call Management:
        bmCapabilities       0x03
          call management
          use DataInterface
        bDataInterface          1

and

19d2:1023  ZTE K4201-z

      CDC Header:
        bcdCDC               1.10
      CDC ACM:
        bmCapabilities       0x02
          line coding and serial state
      CDC Call Management:
        bmCapabilities       0x03
          call management
          use DataInterface
        bDataInterface          1
      CDC Union:
        bMasterInterface        0
        bSlaveInterface         1

The Mediatek example is believed to apply to most smartphones with
Mediatek firmware.  The ZTE example is most likely also part of a larger
family of devices/firmwares.

Tzu-En Huang 5227c2ee45 rtw88: 8822c: add SW DPK support
Power amplifiers are not linear components, and require DPK to
reduce its nonlinearity. DPK is called Digital Pre-distortion
Calibration, can be used to compensate the output of power.

DPK tracking is in charge of tracking the thermal changes. And
it then shifts the power curve accordingly, which makes the
power output remains linear even if the PA works in different
temperature.

To perform DPK, the parameter table should also be updated.
And the table will be applied when device is powered on.
Then DPK will reference the values to calibrate.

Yan-Hsuan Chuang 1ac3294bf7 rtw88: 8822c: add FW IQK support
Add support for doing IQK in firmware

Ideally the RF component's I/Q vectors should be orthogonal,
but usually they are not. So we need to calibrate for the RF
components, ex. PA/LNA, ADC/DAC.

And if the I/Q vectors are more orthogonal, the mixed signal
will have less deviation. This helps with those rates with
higher modulation (MCS8-9), because they have more strict
EVM/SNR requirement. Also the better of the quality of the
signal, the longer it can propagate, and the better throughput
performance we can get.

(u8 *), even though it should be a little-endian word array (__le32 *).
That will be changed in the next patch.

Several places where checkpatch.pl complains about a space after a cast
are fixed.

Larry Finger 360226fdc5 rtlwifi: rtl8723be: Replace local bit manipulation macros
This driver uses a set of local macros to manipulate the RX and TX
descriptors, which are all little-endian quantities. These macros
are replaced by the bitfield macros le32p_replace_bits() and
le32_get_bits(). In several places, the macros operated on an entire
32-bit word. In these cases, a direct read or replacement is used.

Larry Finger 64578a3d34 rtlwifi: rtl8723be: Remove unused SET_XXX and GET_XXX macros
iAs the first step in converting from macros that get/set information
in the RX and TX descriptors, unused macros are being removed.

Larry Finger 773755d911 rtlwifi: rtl8723ae: Convert inline routines to little-endian words
In this step, the read/write routines for the descriptors are converted
to use __le32 quantities, thus a lot of casts can be removed. Callback
routines still use the 8-bit arrays, but these are changed within the
specified routine.

The macro that cleared a descriptor has now been converted into an inline
routine.

Larry Finger a9db071f78 rtlwifi: rtl8723ae: Convert macros that set descriptor
As a first step in the conversion, the macros that set the RX and TX
descriptors are converted to static inline routines, and the names are
changed from upper to lower case. To minimize the changes in a given
step, the input descriptor information is left as as a byte array
(u8 *), even though it should be a little-endian word array (__le32 *).
That will be changed in the next patch.

Several places where checkpatch.pl reports lines too long are fixed.
