  Nothing major, regression fixes are mostly in drivers, two more of

  changes went into -rc5, we'll try to keep an eye on frequency of PRs
  from sub-trees.

  Also disproportional number of fixes for bugs added in v6.4, strange
  coincidence.

  Current release - regressions:

   - igc: fix LED-related deadlock on driver unbind

     process

   - Revert "wifi: iwlwifi: bump FW API to 90 for BZ/SC devices", kernel

     __this_cpu_{add|sub}* are not IRQ-safe

   - dsa: mv88e6xx: fix link setup for 88E6250

  Previous releases - always broken:

   - ip: validate dev returned from __in_dev_get_rcu(), prevent possible
     null-derefs in a few places

   - switch number of for_each_rcu() loops using call_rcu() on the

syzbot reported a lockdep splat regarding unix_gc_lock and
unix_state_lock().

One is called from recvmsg() for a connected socket, and another
is called from GC for TCP_LISTEN socket.

So, the splat is false-positive.

Let's add a dedicated lock class for the latter to suppress the splat.

Note that this change is not necessary for net-next.git as the issue
is only applied to the old GC impl.

b44_free_rings() accesses b44::rx_buffers (and ::tx_buffers)
unconditionally, but b44::rx_buffers is only valid when the
device is up (they get allocated in b44_open(), and deallocated
again in b44_close()), any other time these are just a NULL pointers.

So if you try to change the pause params while the network interface
is disabled/administratively down, everything explodes (which likely
netifd tries to do).

In scenario where pin is registered with multiple parent pins via
dpll_pin_on_pin_register(..), all belonging to the same dpll device.
A second call to dpll_pin_on_pin_unregister(..) would cause a call trace,
as it tries to use already released registration resources (due to fix
introduced in b446631f). In this scenario pin was registered twice,
so resources are not yet expected to be release until each registered
pin/pin pair is unregistered.

Fix by adding a parent pointer as a cookie when creating a registration,

As interrupts are now requested from ravb_probe(), before calling
register_netdev(), ndev->name still contains the template "eth%d",
leading to funny names in /proc/interrupts.  E.g. on R-Car E3:

	89:  0      0  GICv2  93 Level  eth%d:ch22:multi
	90:  0      3  GICv2  95 Level  eth%d:ch24:emac

	93:  0  13735  GICv2  89 Level  eth%d:ch18:tx_be
	94:  0      0  GICv2  90 Level  eth%d:ch19:tx_nc

Worse, on platforms with multiple RAVB instances (e.g. R-Car V4H), all
interrupts have similar names.

Fix this by using the device name instead, like is done in several other
drivers:

	89:  0      0  GICv2  93 Level  e6800000.ethernet:ch22:multi

The CPTS, by design, captures the messageType (Sync, Delay_Req, etc.)
field from the second nibble of the PTP header which is defined in the
PTPv2 (1588-2008) specification. In the PTPv1 (1588-2002) specification
the first two bytes of the PTP header are defined as the versionType
which is always 0x0001. This means that any PTPv1 packets that are
tagged for TX timestamping by the CPTS will have their messageType set
to 0x0 which corresponds to a Sync message type. This causes issues
when a PTPv1 stack is expecting a Delay_Req (messageType: 0x1)
timestamp that never appears.

Fix this by checking if the ptp_class of the timestamped TX packet is
PTP_CLASS_V1 and then matching the PTP sequence ID to the stored
sequence ID in the skb->cb data structure. If the sequence IDs match
and the packet is of type PTPv1 then there is a chance that the
messageType has been incorrectly stored by the CPTS so overwrite the
messageType stored by the CPTS with the messageType from the skb->cb
data structure. This allows the PTPv1 stack to receive TX timestamps
for Delay_Req packets which are necessary to lock onto a PTP Leader.

====================
Fix isolation of broadcast traffic and unmatched unicast traffic with MACsec offload

Some device drivers support devices that enable them to annotate whether a
Rx skb refers to a packet that was processed by the MACsec offloading
functionality of the device. Logic in the Rx handling for MACsec offload
does not utilize this information to preemptively avoid forwarding to the
macsec netdev currently. Because of this, things like multicast messages or
unicast messages with an unmatched destination address such as ARP requests
are forwarded to the macsec netdev whether the message received was MACsec
encrypted or not. The goal of this patch series is to improve the Rx
handling for MACsec offload for devices capable of annotating skbs received
that were decrypted by the NIC offload for MACsec.

Here is a summary of the issue that occurs with the existing logic today.

    * The current design of the MACsec offload handling path tries to use
      "best guess" mechanisms for determining whether a packet associated
      with the currently handled skb in the datapath was processed via HW
      offload
    * The best guess mechanism uses the following heuristic logic (in order of
      precedence)
      - Check if header destination MAC address matches MACsec netdev MAC
        address -> forward to MACsec port
      - Check if packet is multicast traffic -> forward to MACsec port
      - MACsec security channel was able to be looked up from skb offload
        context (mlx5 only) -> forward to MACsec port
    * Problem: plaintext traffic can potentially solicit a MACsec encrypted
      response from the offload device
      - Core aspect of MACsec is that it identifies unauthorized LAN connections
        and excludes them from communication
        + This behavior can be seen when not enabling offload for MACsec
      - The offload behavior violates this principle in MACsec

I believe this behavior is a security bug since applications utilizing
MACsec could be exploited using this behavior, and the correct way to
resolve this is by having the hardware correctly indicate whether MACsec
offload occurred for the packet or not. In the patches in this series, I
leave a warning for when the problematic path occurs because I cannot
figure out a secure way to fix the security issue that applies to the core
MACsec offload handling in the Rx path without breaking MACsec offload for
other vendors.

Shown at the bottom is an example use case where plaintext traffic sent to
a physical port of a NIC configured for MACsec offload is unable to be
handled correctly by the software stack when the NIC provides awareness to
the kernel about whether the received packet is MACsec traffic or not. In
this specific example, plaintext ARP requests are being responded with
MACsec encrypted ARP replies (which leads to routing information being
unable to be built for the requester).

9f74a3df ("ice: Fix VF Reset paths when interface in a failed over
aggregate"), the ice driver has acquired the LAG mutex in ice_reset_vf().
The commit placed this lock acquisition just prior to the acquisition of
the VF configuration lock.

If ice_reset_vf() acquires the configuration lock via the ICE_VF_RESET_LOCK
flag, this could deadlock with ice_vc_cfg_qs_msg() because it always
acquires the locks in the order of the VF configuration lock and then the
LAG mutex.

Lockdep reports this violation almost immediately on creating and then
removing 2 VF:

If the MFS is set below the default (0x2600), a warning message is
reported like the following :

	MFS for port 1 has been set below the default: 600

This message is a bit confusing as the number shown here (600) is in
fact an hexa number: 0x600 = 1536

Without any explicit "0x" prefix, this message is read like the MFS is
set to 600 bytes.

MFS, as per MTUs, are usually expressed in decimal base.

This commit reports both current and default MFS values in decimal
so it's less confusing for end-users.

Can now correctly identify where the packets should be delivered by using
md_dst or its absence on devices that provide it.

This detection is not possible without device drivers that update md_dst. A
fallback pattern should be used for supporting such device drivers. This
fallback mode causes multicast messages to be cloned to both the non-macsec
and macsec ports, independent of whether the multicast message received was
encrypted over MACsec or not. Other non-macsec traffic may also fail to be
handled correctly for devices in promiscuous mode.

Cannot know whether a Rx skb missing md_dst is intended for MACsec or not
without knowing whether the device is able to update this field during an
offload. Assume that an offload to a MACsec device cannot support updating
md_dst by default. Capable devices can advertise that they do indicate that
an skb is related to a MACsec offloaded packet using the md_dst.

There is an smp function call named reset_counters() to init PMU
registers of every CPU in PMU initialization state. It requires that all
CPUs are online. However there is an early_initcall() wrapper for the
PMU init funciton init_hw_perf_events(), so that pmu init funciton is
called in do_pre_smp_initcalls() which before function smp_init().
Function reset_counters() cannot work on other CPUs since they haven't
boot up still.

Here replace the wrapper early_initcall() with pure_initcall(), so that
the PMU init function is called after every cpu is online.

The DP83869 driver sets the MII bit (needed for PHY to work in MII mode)
only if the op-mode is either DP83869_100M_MEDIA_CONVERT or
DP83869_RGMII_100_BASE.

Some drivers i.e. ICSSG support MII mode with op-mode as
DP83869_RGMII_COPPER_ETHERNET for which the MII bit is not set in dp83869
driver. As a result MII mode on ICSSG doesn't work and below log is seen.

TI DP83869 300b2400.mdio:0f: selected op-mode is not valid with MII mode
icssg-prueth icssg1-eth: couldn't connect to phy ethernet-phy@0

Fix this by setting MII bit for DP83869_RGMII_COPPER_ETHERNET op-mode as
well.
