The Broadcom controller on aries S5PV210 boards sends out a couple of
unknown packets after the firmware is loaded. This will cause
logging of errors such as:
Bluetooth: hci0: Frame reassembly failed (-84)
This is probably also the case with other boards, as there are related
Android userspace patches for custom ROMs such as
https://review.lineageos.org/#/c/LineageOS/android_system_bt/+/142721/
Since this appears to be intended behaviour, treated them as diagnostic
packets.
Note that this is another variant of commit 01d5e44ace8a

mac80211 uses the frag list to build AMSDU. When freeing
the skb, it may not be really freed, since someone is still
holding a reference to it.
In that case, when TCP skb is being retransmitted, the
pointer to the frag list is being reused, while the data
in there is no longer valid.
Since we will never get frag list from the network stack,
as mac80211 doesn't advertise the capability, we can safely
free and nullify it before releasing the SKB.

Due to the alignment handling, it actually matters where in the code
we add the 4 bytes for the presence bitmap to the length; the first
field is the timestamp with 8 byte alignment so we need to add the
space for the extra vendor namespace presence bitmap *before* we do
any alignment for the fields.
Move the presence bitmap length accounting to the right place to fix
the alignment for the data properly.

NAME_DISTRIBUTOR messages are transmitted through unicast link on TIPC

TIPC 1.7. But at present, NAME_DISTRIBUTOR messages received by
broadcast link cannot be handled in tipc_rcv() until an unicast message
arrives, which may lead to a significant delay to update name table.
To avoid this delay, we will also deal with broadcast NAME_DISTRIBUTOR

Even though the link is down before entering hibernation,
there is an issue that the network interface always links up after resuming
from hibernation.
If the link is still down before enabling the network interface,
and after resuming from hibernation, the phydev->state is forcibly set
to PHY_UP in mdio_bus_phy_restore(), and the link becomes up.
In suspend sequence, only if the PHY is attached, mdio_bus_phy_suspend()
calls phy_stop_machine(), and mdio_bus_phy_resume() calls
phy_start_machine().
In resume sequence, it's enough to do the same as mdio_bus_phy_resume()
because the state has been preserved.
This patch fixes the issue by calling phy_start_machine() in
mdio_bus_phy_restore() in the same way as mdio_bus_phy_resume().

Current state for the lan78xx driver does not allow for changing the
MAC address of the interface, without either removing the module (if
you compiled it that way) or rebooting the machine. If you attempt to
change the MAC address, ifconfig will show the new address, however,
the system/interface will not respond to any traffic using that
configuration. A few short-term options to work around this are to
unload the module and reload it with the new MAC address, change the
interface to "promisc", or reboot with the correct configuration to
change the MAC.
This patch enables the ability to change the MAC address via fairly normal means...
ifdown <interface>
modify entry in /etc/network/interfaces OR a similar method
ifup <interface>
Then test via any network communication, such as ICMP requests to gateway.
My only test platform for this patch has been a raspberry pi model 3b+.

vxlan: Various fixes
This patch set contains three fixes for the vxlan driver.
Patch #1 fixes handling of offload mark on replaced VXLAN FDB entries. A
way to trigger this is to replace the FDB entry with one that can not be
offloaded. A future patch set should make it possible to veto such FDB
changes. However the FDB might still fail to be offloaded due to another
issue, and the offload mark should reflect that.
Patch #2 fixes problems in __vxlan_dev_create() when a call to
rtnl_configure_link() fails. These failures would be tricky to hit on a
real system, the most likely vector is through an error in vxlan_open().
However, with the abovementioned vetoing patchset, vetoing the created
entry would trigger the same problems (and be easier to reproduce).
Patch #3 fixes a problem in vxlan_changelink(). In situations where the
default remote configured in the FDB table (if any) does not exactly
match the remote address configured at the VXLAN device, changing the
remote address breaks the default FDB entry. Patch #4 is then a self
test for this issue.
v3:
- Patch #2:
- Reuse the same errout block for both cleanup paths. Use a bool to
decide whether the unregister_netdevice() call should be made.
v2:
- Drop former patch #3
- Patch #2:
- Delete the default entry before calling unregister_netdevice(). That
takes care of former patch #3, hence tweak the commit message to
mention that problem as well.

Default remotes are stored as FDB entries with an Ethernet address of
00:00:00:00:00:00. When a request is made to change a remote address of
a VXLAN device, vxlan_changelink() first deletes the existing default
remote, and then creates a new FDB entry.
This works well as long as the list of default remotes matches exactly
the configuration of a VXLAN remote address. Thus when the VXLAN device
has a remote of X, there should be exactly one default remote FDB entry
X. If the VXLAN device has no remote address, there should be no such
entry.
Besides using "ip link set", it is possible to manipulate the list of
default remotes by using the "bridge fdb". It is therefore easy to break
the above condition. Under such circumstances, the __vxlan_fdb_delete()
call doesn't delete the FDB entry itself, but just one remote. The
following vxlan_fdb_create() then creates a new FDB entry, leading to a
situation where two entries exist for the address 00:00:00:00:00:00,
each with a different subset of default remotes.
An even more obvious breakage rooted in the same cause can be observed
when a remote address is configured for a VXLAN device that did not have
one before. In that case vxlan_changelink() doesn't remove any remote,
and just creates a new FDB entry for the new address:
$ ip link add name vx up type vxlan id 2000 dstport 4789
$ bridge fdb ap dev vx 00:00:00:00:00:00 dst 192.0.2.20 self permanent
$ bridge fdb ap dev vx 00:00:00:00:00:00 dst 192.0.2.30 self permanent
$ ip link set dev vx type vxlan remote 192.0.2.30
$ bridge fdb sh dev vx | grep 00:00:00:00:00:00
00:00:00:00:00:00 dst 192.0.2.30 self permanent <- new entry, 1 rdst
00:00:00:00:00:00 dst 192.0.2.20 self permanent <- orig. entry, 2 rdsts
00:00:00:00:00:00 dst 192.0.2.30 self permanent
To fix this, instead of calling vxlan_fdb_create() directly, defer to
vxlan_fdb_update(). That has logic to handle the duplicates properly.
Additionally, it also handles notifications, so drop that call from
changelink as well.

When a failure occurs in rtnl_configure_link(), the current code
calls unregister_netdevice() to roll back the earlier call to
register_netdevice(), and jumps to errout, which calls
vxlan_fdb_destroy().
However unregister_netdevice() calls transitively ndo_uninit, which is
vxlan_uninit(), and that already takes care of deleting the default FDB
entry by calling vxlan_fdb_delete_default(). Since the entry added
earlier in __vxlan_dev_create() is exactly the default entry, the
cleanup code in the errout block always leads to double free and thus a
panic.
Besides, since vxlan_fdb_delete_default() always destroys the FDB entry
with notification enabled, the deletion of the default entry is notified
even before the addition was notified.
Instead, move the unregister_netdevice() call after the manual destroy,
which solves both problems.

When rdst of an offloaded FDB entry is replaced, it certainly isn't
offloaded anymore. Drivers are notified about such replacements, and can
re-mark the entry as offloaded again if they so wish. However until a
driver does so explicitly, assume a replaced FDB entry is not offloaded.
Note that replaces coming via vxlan_fdb_external_learn_add() are always
immediately followed by an explicit offload marking.

When reading buffer descriptors on RX or on TX completion, an
RX_USED/TX_USED bit is checked first to ensure that the descriptors have
been populated, i.e. the ownership has been transferred. However, there
are no memory barriers to ensure that the data protected by the
RX_USED/TX_USED bit is up-to-date with respect to that bit.
Specifically:
- TX timestamp descriptors may be loaded before ctrl is loaded for the
TX_USED check, which is racy as the descriptors may be updated between
the loads, causing old timestamp descriptor data to be used.
- RX ctrl may be loaded before addr is loaded for the RX_USED check,
which is racy as a new frame may be written between the loads, causing
old ctrl descriptor data to be used.
This issue exists for both macb_rx() and gem_rx() variants.
Fix the races by adding DMA read memory barriers on those paths and
reordering the reads in macb_rx().
I have not observed any actual problems in practice caused by these
being missing, though.

Bit RX_USED set to 0 in the address field allows the controller to write
data to the receive buffer descriptor.
The driver does not ensure the ctrl field is ready (cleared) when the
controller sees the RX_USED=0 written by the driver. The ctrl field might
only be cleared after the controller has already updated it according to
a newly received frame, causing the frame to be discarded in gem_rx() due
to unexpected ctrl field contents.
A message is logged when the above scenario occurs:
macb ff0b0000.ethernet eth0: not whole frame pointed by descriptor
Fix the issue by ensuring that when the controller sees RX_USED=0 the
ctrl field is already cleared.

64-bit DMA addresses are split in upper and lower halves that are
written in separate fields on GEM. For RX, bit 0 of the address is used
as the ownership bit (RX_USED). When the RX_USED bit is unset the
controller is allowed to write data to the buffer.
The driver does not guarantee that the controller already sees the upper
half when the RX_USED bit is cleared, possibly resulting in the
controller writing an incoming frame to an address with an incorrect
upper half and therefore possibly corrupting unrelated system memory.
Fix that by adding the necessary DMA memory barrier between the writes.
This corruption was observed on a ZynqMP based system.

On some platforms (currently detected only on SAMA5D4) TX might stuck
even the pachets are still present in DMA memories and TX start was
issued for them. This happens due to race condition between MACB driver
updating next TX buffer descriptor to be used and IP reading the same
descriptor. In such a case, the "TX USED BIT READ" interrupt is asserted.
GEM/MACB user guide specifies that if a "TX USED BIT READ" interrupt
is asserted TX must be restarted. Restart TX if used bit is read and
packets are present in software TX queue. Packets are removed from software
TX queue if TX was successful for them (see macb_tx_interrupt()).

On many devices the RTL8723BS device gets reset during suspend/resume,
causing it to lose its firmware and all state.
Testing has shown it drops back to communicating at 115200 bps and sends
sync-request packages, indicating it has been fully reset.
This commit fixes this by queueing a reprobe on resume.
This mirrors how USB RTL BT devices, which have the same problem, are
handled in the btusb driver, there we set the USB_QUIRK_RESET_RESUME for
all RTL devices, which also causes a reprobe on resume. The only difference
is that here we need to do the reprobe ourselves.
Since we are doing a full reprobe on resume now, we can also turn off the
device on suspend to save power while suspended.

Current btf internal verbose logger logs fwd type as
[2] FWD A type_id=0
where A is the type name.
Commit 9d5f9f701b18 ("bpf: btf: fix struct/union/fwd types
with kind_flag") introduced kind_flag which can be used
to distinguish whether a forward type is a struct or
union.
Also, "type_id=0" does not carry any meaningful
information for fwd type as btf_type.type = 0 is simply
enforced during btf verification and is not used
anywhere else.
This commit changed the log to
[2] FWD A struct
if kind_flag = 0, or
[2] FWD A union
if kind_flag = 1.

Similar to commit 143ece654f9f ("tipc: check tsk->group in tipc_wait_for_cond()")
we have to reload grp->dests too after we re-take the sock lock.
This means we need to move the dsts check after tipc_wait_for_cond()
too.

HCI_QUIRK_RESET_ON_CLOSE quirk is required for BT v1.0 based devices,
to send a reset command to the chip during hci device close. Serdev
architecture is used for the latest BT chips, which doesn't require to
send the reset command during close. If still chips required reset
command during close, it would be better enabling it in the vendor
probes or in proto setup.

John Fastabend says:
====================
This adds a size field to the sk_msg_md data structure used by SK_MSG
programs. Without this in the zerocopy case and in the copy case
where multiple iovs are in use its difficult to know how much data
can be pulled in. The normal method of reading data and data_end
only give the current contiguous buffer. BPF programs can attempt to
pull in extra data but have to guess if it exists. This can result
in multiple "guesses" its much better if we know upfront the size
of the sk_msg.

The BCM43430A0 has the default MAC address 43:43:A0:12:1F:AC if none
is given. This address was found when enabling Bluetooth on a bunch of
boards with the AMPAK AP6210 module, all sharing the same address. It
also contains the sequence 4343A0, which is suspicious as that is also
the name the chip identifies itself as.
Add this to the list of default MAC addresses and leave it to the user
to configure a valid one.
