dd1b527831 net: add location to trace_consume_skb()
kfree_skb() includes the location, it makes sense
to add it to consume_skb() as well.

c078381856 rxrpc: Fix overproduction of wakeups to recvmsg()
Fix three cases of overproduction of wakeups:

 (1) rxrpc_input_split_jumbo() conditionally notifies the app that there's
     data for recvmsg() to collect if it queues some data - and then its
     only caller, rxrpc_input_data(), goes and wakes up recvmsg() anyway.

     Fix the rxrpc_input_data() to only do the wakeup in failure cases.

 (2) If a DATA packet is received for a call by the I/O thread whilst
     recvmsg() is busy draining the call's rx queue in the app thread, the
     call will left on the recvmsg() queue for recvmsg() to pick up, even
     though there isn't any data on it.

     This can cause an unexpected recvmsg() with a 0 return and no MSG_EOR
     set after the reply has been posted to a service call.

     Fix this by discarding pending calls from the recvmsg() queue that
     don't need servicing yet.

 (3) Not-yet-completed calls get requeued after having data read from them,
     even if they have no data to read.

     Fix this by only requeuing them if they have data waiting on them; if
     they don't, the I/O thread will requeue them when data arrives or they
     fail.

b20b8aec6f devlink: Fix netdev notifier chain corruption
Cited commit changed devlink to register its netdev notifier block on
the global netdev notifier chain instead of on the per network namespace
one.

However, when changing the network namespace of the devlink instance,
devlink still tries to unregister its notifier block from the chain of
the old namespace and register it on the chain of the new namespace.
This results in corruption of the notifier chains, as the same notifier
block is registered on two different chains: The global one and the per
network namespace one. In turn, this causes other problems such as the
inability to dismantle namespaces due to netdev reference count issues.

Fix by preventing devlink from moving its notifier block between
namespaces.

Reproducer:

 # echo "10 1" > /sys/bus/netdevsim/new_device
 # ip netns add test123
 # devlink dev reload netdevsim/netdevsim10 netns test123
 # ip netns del test123
 [   71.935619] unregister_netdevice: waiting for lo to become free. Usage count = 2
 [   71.938348] leaked reference.

1a30a6b25f wifi: brcmfmac: p2p: Introduce generic flexible array frame member
Silence run-time memcpy() false positive warning when processing
management frames:

  memcpy: detected field-spanning write (size 27) of single field "&mgmt_frame->u" at drivers/net/wireless/broadcom/brcm80211/brcmfmac/p2p.c:1469 (size 26)

Due to this (soon to be fixed) GCC bug[1], FORTIFY_SOURCE (via
__builtin_dynamic_object_size) doesn't recognize that the union may end
with a flexible array, and returns "26" (the fixed size of the union),
rather than the remaining size of the allocation. Add an explicit
flexible array member and set it as the destination here, so that we
get the correct coverage for the memcpy().

Saeed Mahameed says:

====================
mlx5-updates-2023-02-10

1) From Roi and Mark: MultiPort eswitch support

MultiPort E-Switch builds on newer hardware's capabilities and introduces
a mode where a single E-Switch is used and all the vports and physical
ports on the NIC are connected to it.

The new mode will allow in the future a decrease in the memory used by the
driver and advanced features that aren't possible today.

This represents a big change in the current E-Switch implantation in mlx5.
Currently, by default, each E-Switch manager manages its E-Switch.
Steering rules in each E-Switch can only forward traffic to the native
physical port associated with that E-Switch. While there are ways to target
non-native physical ports, for example using a bond or via special TC
rules. None of the ways allows a user to configure the driver
to operate by default in such a mode nor can the driver decide
to move to this mode by default as it's user configuration-driven right now.

While MultiPort E-Switch single FDB mode is the preferred mode, older
generations of ConnectX hardware couldn't support this mode so it was never
implemented. Now that there is capable hardware present, start the
transition to having this mode by default.

Introduce a devlink parameter to control MultiPort Eswitch single FDB mode.
This will allow users to select this mode on their system right now
and in the future will allow the driver to move to this mode by default.

Commit e48c414ee6 ("[INET]: Generalise the TCP sock ID lookup routines")
commented out the definition of SOCK_REFCNT_DEBUG in 2005 and later another
commit 463c84b97f ("[NET]: Introduce inet_connection_sock") removed it.
Since we could track all of them through bpf and kprobe related tools
and the feature could print loads of information which might not be
that helpful even under a little bit pressure, the whole feature which
has been inactive for many years is no longer supported.

6e4c0d0460 wifi: mac80211: add a workaround for receiving non-standard mesh A-MSDU
At least ath10k and ath11k supported hardware (maybe more) does not implement
mesh A-MSDU aggregation in a standard compliant way.
802.11-2020 9.3.2.2.2 declares that the Mesh Control field is part of the
A-MSDU header (and little-endian).
As such, its length must not be included in the subframe length field.
Hardware affected by this bug treats the mesh control field as part of the
MSDU data and sets the length accordingly.
In order to avoid packet loss, keep track of which stations are affected
by this and take it into account when converting A-MSDU to 802.3 + mesh control
packets.

986e43b19a wifi: mac80211: fix receiving A-MSDU frames on mesh interfaces
The current mac80211 mesh A-MSDU receive path fails to parse A-MSDU packets
on mesh interfaces, because it assumes that the Mesh Control field is always
directly after the 802.11 header.
802.11-2020 9.3.2.2.2 Figure 9-70 shows that the Mesh Control field is
actually part of the A-MSDU subframe header.
This makes more sense, since it allows packets for multiple different
destinations to be included in the same A-MSDU, as long as RA and TID are
still the same.
Another issue is the fact that the A-MSDU subframe length field was apparently
accidentally defined as little-endian in the standard.

In order to fix this, the mesh forwarding path needs happen at a different
point in the receive path.

ieee80211_data_to_8023_exthdr is changed to ignore the mesh control field
and leave it in after the ethernet header. This also affects the source/dest
MAC address fields, which now in the case of mesh point to the mesh SA/DA.

ieee80211_amsdu_to_8023s is changed to deal with the endian difference and
to add the Mesh Control length to the subframe length, since it's not covered
by the MSDU length field.

With these changes, the mac80211 will get the same packet structure for
converted regular data packets and unpacked A-MSDU subframes.

The mesh forwarding checks are now only performed after the A-MSDU decap.
For locally received packets, the Mesh Control header is stripped away.
For forwarded packets, a new 802.11 header gets added.

Currently authentication request event interface doesn't have support to
indicate the user space whether it should enable MLO or not during the
authentication with the specified AP. But driver needs such capability
since the connection is MLO or not decided by the driver in case of SME
offload to the driver.

Add support for driver to indicate MLD address of the AP in
authentication offload request to inform user space to enable MLO during
authentication process. Driver shall look at NL80211_ATTR_MLO_SUPPORT
flag capability in NL80211_CMD_CONNECT to know whether the user space
supports enabling MLO during the authentication offload.

User space should enable MLO during the authentication only when it
receives the AP MLD address in authentication offload request. User
space shouldn't enable MLO if the authentication offload request doesn't
indicate the AP MLD address even if the AP is MLO capable.

When MLO is enabled, user space should use the MAC address of the
interface (on which driver sent request) as self MLD address. User space
and driver to use MLD addresses in RA, TA and BSSID fields of the frames
between them, and driver translates the MLD addresses to/from link
addresses based on the link chosen for the authentication.

There are currently two mechanisms for populating hardware stats:
1. Using flow_offload api to query the flow's statistics.
   The api assumes that the same stats values apply to all
   the flow's actions.
   This assumption breaks when action drops or jumps over following
   actions.
2. Using hw_action api to query specific action stats via a driver
   callback method. This api assures the correct action stats for
   the offloaded action, however, it does not apply to the rest of the
   actions in the flow's actions array.

Extend the flow_offload stats callback to indicate that a per action
stats update is required.
Use the existing flow_offload_action api to query the action's hw stats.
In addition, currently the tc action stats utility only updates hw actions.
Reuse the existing action stats cb infrastructure to query any action
stats.

bba047f158 wifi: mwifiex: Support SD8978 chipset
The Marvell SD8978 (aka NXP IW416) uses identical registers as SD8987,
so reuse the existing mwifiex_reg_sd8987 definition.

Note that mwifiex_reg_sd8977 and mwifiex_reg_sd8997 are likewise
identical, save for the fw_dump_ctrl register:  They define it as 0xf0
whereas mwifiex_reg_sd8987 defines it as 0xf9.  I've verified that
0xf9 is the correct value on SD8978.  NXP's out-of-tree driver uses
0xf9 for all of them, so there's a chance that 0xf0 is not correct
in the mwifiex_reg_sd8977 and mwifiex_reg_sd8997 definitions.  I cannot
test that for lack of hardware, hence am leaving it as is.

NXP has only released a firmware which runs Bluetooth over UART.
Perhaps Bluetooth over SDIO is unsupported by this chipset.
Consequently, only an "sdiouart" firmware image is referenced, not an
alternative "sdsd" image.

022c3f87f8 net: phy: add genphy_c45_ethtool_get/set_eee() support
Add replacement for phy_ethtool_get/set_eee() functions.

Current phy_ethtool_get/set_eee() implementation is great and it is
possible to make it even better:
- this functionality is for devices implementing parts of IEEE 802.3
  specification beyond Clause 22. The better place for this code is
  phy-c45.c
- currently it is able to do read/write operations on PHYs with
  different abilities to not existing registers. It is better to
  use stored supported_eee abilities to avoid false read/write
  operations.
- the eee_active detection will provide wrong results on not supported
  link modes. It is better to validate speed/duplex properties against
  supported EEE link modes.
- it is able to support only limited amount of link modes. We have more
  EEE link modes...

By refactoring this code I address most of this point except of the last
one. Adding additional EEE link modes will need more work.
