[ Upstream commit 925ab1aa9394bbaeac47ee5b65d3fdf0fb8135cf ]
It's forbidden to manually change dev->features in run-time. Currently, this is
done in the driver to make sure that GSO_UDP_TUNNEL is advertized only when
VXLAN tunnel is set. However, since the stack actually does features intersection
with hw_enc_features, we can safely revert to advertizing features early when
registering the netdevice.

[ Upstream commit 31c128b66e5b28f468076e4f3ca3025c35342041 ]
Previously, the shift value used for time-stamping was constant and didn't
depend on the HW chip frequency. Change that to take the frequency into account
and calculate the maximal value in cycles per wraparound of ten seconds. This
time slot was chosen since it gives a good accuracy in time synchronization.
Algorithm for shift value calculation:
* Round up the maximal value in cycles to nearest power of two
* Calculate maximal multiplier by division of all 64 bits set
to above result
* Then, invert the function clocksource_khz2mult() to get the shift from
maximal mult value

RdropOvflw counts overrun of HW buffer, therefore should
be used for rx_fifo_errors only.
Currently RdropOvflw counter is mistakenly also set into
rx_missed_errors and rx_over_errors too, which makes the

[ Upstream commit 21a75f0915dde8674708b39abfcda113911c49b1 ]
The current logic in bond_arp_rcv will accept an incoming ARP for
validation if (a) the receiving slave is either "active" (which includes
the currently active slave, or the current ARP slave) or, (b) there is a
currently active slave, and it has received an ARP since it became active.
For case (b), the receiving slave isn't the currently active slave, and is
receiving the original broadcast ARP request, not an ARP reply from the
target.
This logic can fail if there is no currently active slave. In
this situation, the ARP probe logic cycles through all slaves, assigning
each in turn as the "current_arp_slave" for one arp_interval, then setting
that one as "active," and sending an ARP probe from that slave. The
current logic expects the ARP reply to arrive on the sending
current_arp_slave, however, due to switch FDB updating delays, the reply
may be directed to another slave.
This can arise if the bonding slaves and switch are working, but
the ARP target is not responding. When the ARP target recovers, a
condition may result wherein the ARP target host replies faster than the
switch can update its forwarding table, causing each ARP reply to be sent
to the previous current_arp_slave. This will never pass the logic in
bond_arp_rcv, as neither of the above conditions (a) or (b) are met.
Some experimentation on a LAN shows ARP reply round trips in the
200 usec range, but my available switches never update their FDB in less
than 4000 usec.
This patch changes the logic in bond_arp_rcv to additionally
accept an ARP reply for validation on any slave if there is a current ARP
slave and it sent an ARP probe during the previous arp_interval.

[ Upstream commit b7d987295c74500b733a0ba07f9a9bcc4074fa83 ]
tg3_tso_bug() can hit a condition where the entire tx ring is not big
enough to segment the GSO packet. For example, if MSS is very small,
gso_segs can exceed the tx ring size. When we hit the condition, it
will cause tx timeout.
tg3_tso_bug() is called to handle TSO and DMA hardware bugs.
For TSO bugs, if tg3_tso_bug() cannot succeed, we have to drop the packet.
For DMA bugs, we can still fall back to linearize the SKB and let the
hardware transmit the TSO packet.
This patch adds a function tg3_tso_bug_gso_check() to check if there
are enough tx descriptors for GSO before calling tg3_tso_bug().
The caller will then handle the error appropriately - drop or
lineraize the SKB.

[ Upstream commit 4f2c6ae5c64c353fb1b0425e4747e5603feadba1 ]
When switchdev drivers process FDB notifications from the underlying
device they resolve the netdev to which the entry points to and notify
the bridge using the switchdev notifier.
However, since the RTNL mutex is not held there is nothing preventing
the netdev from disappearing in the middle, which will cause
br_switchdev_event() to dereference a non-existing netdev.
Make switchdev drivers hold the lock at the beginning of the
notification processing session and release it once it ends, after
notifying the bridge.
Also, remove switchdev_mutex and fdb_lock, as they are no longer needed
when RTNL mutex is held.

[ Upstream commit db0e51afa481088e6396f11e02018d64113a6578 ]
Since commit 76e398a62712 ("net: dsa: use switchdev obj for VLAN add/del
ops"), the Marvell 88E6xxx switch has been unable to pass traffic
between ports - any received traffic is discarded by the switch.
Taking a port out of bridge mode and configuring a vlan on it also the
port to start passing traffic.
With the debugfs files re-instated to allow debug of this issue by
comparing the register settings between the working and non-working
case, the reason becomes clear:
GLOBAL GLOBAL2 SERDES 0 1 2 3 4 5 6
- 7: 1111 707f 2001 2 2 2 2 2 0 2
+ 7: 1111 707f 2001 1 1 1 1 1 0 1
Register 7 for the ports is the default vlan tag register, and in the
non-working setup, it has been set to 2, despite vlan 2 not being
configured. This causes the switch to drop all packets coming in to
these ports. The working setup has the default vlan tag register set
to 1, which is the default vlan when none is configured.
Inspection of the code reveals why. The code prior to this commit
was:
- for (vid = vlan->vid_begin; vid <= vlan->vid_end; ++vid) {
...
- if (!err && vlan->flags & BRIDGE_VLAN_INFO_PVID)
- err = ds->drv->port_pvid_set(ds, p->port, vid);
but the new code is:
+ for (vid = vlan->vid_begin; vid <= vlan->vid_end; ++vid) {
...
+ }
...
+ if (pvid)
+ err = _mv88e6xxx_port_pvid_set(ds, port, vid);
This causes the new code to always set the default vlan to one higher
than the old code.
Fix this.

[ Upstream commit 9a368aff9cb370298fa02feeffa861f2db497c18 ]
Several times already this has been reported as kasan reports caused by
syzkaller and trinity and people always looked at RCU races, but it is
much more simple. :)
In case we bind a pptp socket multiple times, we simply add it to
the callid_sock list but don't remove the old binding. Thus the old
socket stays in the bucket with unused call_id indexes and doesn't get
cleaned up. This causes various forms of kasan reports which were hard
to pinpoint.
Simply don't allow multiple binds and correct error handling in
pptp_bind. Also keep sk_state bits in place in pptp_connect.

When configuring checksums on UDP tunnels, the flags are different
for IPv4 vs. IPv6 (and reversed). However, when lightweight tunnels
are enabled the flags used are always the IPv4 versions, which are

checksums can be controlled appropriately.

[ Upstream commit 81e8f2e930fe76b9814c71b9d87c30760b5eb705 ]
PHY status frames are not reliable, the PHY may not be able to send them
during heavy receive traffic. This overflow condition is signaled by the
PHY in the next status frame, but the driver did not make use of it.
Instead it always reported wrong tx timestamps to user space after an
overflow happened because it assigned newly received tx timestamps to old
packets in the queue.
This commit fixes this issue by clearing the tx timestamp queue every time
an overflow happens, so that no timestamps are delivered for overflow
packets. This way time stamping will continue correctly after an overflow.

The nl80211 layer expects P2P search operation to be aborted
if needed when stopping P2P device. If the P2P search operation
is still running after returning from stop_p2p_device
it causes a WARN_ON and possibly a kernel crash.
Fix this by aborting the P2P search in wil_cfg80211_stop_p2p_device
and preventing P2P search from being started on a stopped P2P
device.
Note, the fix does not cover the case where a regular scan
is started on the P2P device. It will be completed in the
future when support is added for aborting a scan operation.

In case we fail to map one of the TSO SKB fragments, we need to
clear all the mapped descriptors, from swhead to swhead+descs_used-1.
Change the desc index calculation to
i = (swhead + descs_used - 1) % vring->size;
to prevent unmpping of (swhead + descs_used) descriptor that wasn't
mapped.

napi_synchronize is called before releasing the vring, with the
assumption that setting txdata->enabled to 0 will prevent handling
of this vring in the next scheduled napi.
To guarantee this assumption, a memory barrier is added after disabling
the txdata.
In addition, as the ctx is zeroed in wil_tx_complete after this
descriptor is handled (protected by wmb), ctx needs to be checked
before releasing this descriptor in wil_vring_free.

There are 2 possible race conditions, both are solved by addition of
memory barrier:
1. wil_tx_complete reads the swhead to determine if the vring is
empty. In case the swhead was updated before the descriptor update
was performed in __wil_tx_vring/__wil_tx_vring_tso, the completion
loop will not end and as the DU bit may still be set from a previous
run, this skb can be handled as completed before it was sent, which
will lead to double free of the same SKB.
2. __wil_tx_vring/__wil_tx_vring_tso calculate the number of available
descriptors according to the swtail. In case the swtail is updated
before memset of ctx to zero is completed, we can handle this
descriptor while later on ctx is zeroed.

In idle times 60G device can enter deep sleep and turn off
its XTAL clock.
Host access triggers the device power-up flow which will hold
the AHB during XTAL stabilization until device switches from
slow-clock to XTAL clock.
This behavior can stall the PCIe bus for some arbitrary period
of time.
In order to prevent this stall, host can vote for High Latency
Access Policy (HALP) before reading from PCIe bus.
This vote will wakeup the device from deep sleep and prevent
deep sleep until unvote is done.

P2P search can only run on the social channel (channel 2).
When issuing a scan request on the P2P_DEVICE interface,
driver ignored the channels argument and always performed a P2P
search.
Fix this by checking the channels argument, if it is
not specified (meaning full scan) or if a non-social channel
was specified, perform a regular scan and not a P2P search.

driver for dual WiFi.
Refactor the common api and data structure to avoid namespace
collision compilation error. Refactor sdio and pcie bus specific
kernel api and removed conditional compilation config flag.
The platform driver at run time identifies the wlan bus type
from the PHY device pointer passed by the wlan driver through
vos api and cnss platform driver redirects the cnss api according
the bus type.
Remove conditional compilation flag from cnss common api and
update cnss makefile for dual platform driver compilation
with single config flag.

Fix 2 race conditions found during test runs of P2P discovery:
1. Because wil_p2p_cancel_listen was not protected, user space
could start a new P2P listen/search before wmi_stop_discovery
completed. This caused a crash in the firmware.
2. In P2P listen, when listen timer expires and user space calls
cancel_remain_on_channel at the same time, code could send the
cfg80211_remain_on_channel_expired notification twice.
Added protections with wil->mutex to several places that call
wmi_stop_discovery.

Added support for the P2P_DEVICE virtual interface. This interface
is intended for P2P management operations such as discovery and
GO negotiation. Normally it is implemented by drivers to allow
a separate interface for P2P management with its own MAC address,
but for 11ad drivers it is needed to support P2P search, since it
cannot otherwise be separated from normal scan.
Since we only support a single interface/MAC address, we can't
easily separate between primary and P2P_DEVICE interfaces.
For example when a management packet arrives we can't tell for
which interface it is intended. To work around this, we store
a pointer to the interface where the last "radio operation" was
triggered such as scan or remain on channel, and we forward
management packets and scan results to this interface.

PBSS (Personal Basic Service Set) is a new BSS type for DMG
networks. It is similar to infrastructure BSS, having an AP-like
entity called PCP (PBSS Control Point), but it has few differences.
For example, stations inside a PBSS can communicate directly, and
the PCP role can be transferred between stations.
This change adds PBSS support, and has 2 main parts:
1. When starting an AP, add an option to start as a PCP instead.
This is implemented by a new PBSS flag which is passed as part of
the cfg80211_ap_settings structure.
2. When connecting to a BSS, add an option to connect to a PCP
instead of an AP. This is again implemented by a new PBSS flag,
added to the cfg80211_connect_params structure.

In previous commit cd958296acba
("wil6210: enable WA for PCIe HW errata")
relaxed ordering (bit 5) was set, in addition
to the 'No snoop" setting.
Enabling relaxed ordering can cause a race condition
between the write transactions and interrupts when
using INT instead of MSI.
As relaxed ordering is not required to resolve the
PCIe HW issue, it should be disabled.

PBSS (Personal Basic Service Set) is a new BSS type for DMG
networks. It is similar to infrastructure BSS, having an AP-like
entity called PCP (PBSS Control Point), but it has few differences.
PBSS support is mandatory for 11ad devices.
Add support for PBSS by introducing a new PBSS flag attribute.
The PBSS flag is used in the START_AP command to request starting
a PCP instead of an AP, and in the CONNECT command to request
connecting to a PCP instead of an AP.

Switch to auto-generated version of wmi.h which is maintained
by FW team. This will allow better sync between teams in the
future and avoid bugs because of unexpected API changes.
The wmi.h will have many differences but most are cosmetic.
It also includes these real differences:
1. is_go parameter added to BCON_CTRL and START_PCP commands.
2. max_rx_pl_per_desc added to CFG_RX_CHAIN command.
3. various small API updates that are not currently used by
driver.

Add support for discovery mode during scan. When discovery mode
is active, station transmits special beacons while scanning.
This can optimize the scan mainly when there is only one AP/PCP
around.
Discovery mode is implicitly used by firmware during P2P search.
Since there is currently no use case where user space has a
reason to directly control discovery mode, we expose it only
through a debugfs flag.
Also fix name confusion in the wmi_scan_type enumeration.
The type previously called WMI_LONG_SCAN is actually
WMI_ACTIVE_SCAN.
