commit af199a1a9cb02ec0194804bd46c174b6db262075 upstream.
The number of ports is incorrectly set to the maximum available for a DSA
switch. Even if the extra ports are not used, this causes some functions
to be called later, like port_disable() and port_stp_state_set(). If the
driver doesn't check the port index, it will end up modifying unknown
registers.

commit 4d3da2d8d91f66988a829a18a0ce59945e8ae4fb upstream.
While trying to use the lantiq_gswip driver on one of my boards I made
a mistake when specifying the phy-mode (because the out-of-tree driver
wants phy-mode "gmii" or "mii" for the internal PHYs). In this case the
following error is printed multiple times:
Unsupported interface: 3
While it gives at least a hint at what may be wrong it is not very user
friendly. Print the human readable phy-mode and also which port is
configured incorrectly (this hardware supports ports 0..6) to improve
the cases where someone made a mistake.

commit 1c6463b6fc36f2261df1a68ee13a5ebd980914b1 upstream.
The current mv88e6xxx_smi_direct_wait function is only used to check
the 16th bit of the (16-bit) SMI Command register. But the bit shift
operation is not enough if we eventually use this function to check
other bits, thus replace it with a mask.

commit 38152ea37d8bdaffa22603e0a5b5b86cfa8714c9 upstream.
Currently, setting a bridge's self PVID to other value and deleting
the default VID 1 renders untagged ports of that VLAN unable to talk to
the CPU port:
bridge vlan add dev br0 vid 2 pvid untagged self
bridge vlan del dev br0 vid 1 self
bridge vlan add dev sw0p0 vid 2 pvid untagged
bridge vlan del dev sw0p0 vid 1
# br0 cannot send untagged frames out of sw0p0 anymore
That is because the CPU port is set to security mode and its PVID is
still 1, and untagged frames are dropped due to VLAN member violation.
Set the CPU port to fallback mode so untagged frames can pass through.

commit 5e5502e012b8129e11be616acb0f9c34bc8f8adb upstream.
When a client moves from a DSA user port to a software port in a bridge,
it cannot reach any other clients that connected to the DSA user ports.
That is because SA learning on the CPU port is disabled, so the switch
ignores the client's frames from the CPU port and still thinks it is at
the user port.
Fix it by enabling SA learning on the CPU port.
To prevent the switch from learning from flooding frames from the CPU
port, set skb->offload_fwd_mark to 1 for unicast and broadcast frames,
and let the switch flood them instead of trapping to the CPU port.
Multicast frames still need to be trapped to the CPU port for snooping,
so set the SA_DIS bit of the MTK tag to 1 when transmitting those frames
to disable SA learning.

commit 6344dbde6a27d10d16246d734b968f84887841e2 upstream.
When asking the ARL to read a MAC address, we will get a number of bins
returned in a single read. Out of those bins, there can essentially be 3
states:
- all bins are full, we have no space left, and we can either replace an
existing address or return that full condition
- the MAC address was found, then we need to return its bin index and
modify that one, and only that one
- the MAC address was not found and we have a least one bin free, we use
that bin index location then
The code would unfortunately fail on all counts.

Commit f949a12fd697 ("net: dsa: bcm_sf2: fix buffer overflow doing
set_rxnfc") tried to fix the some user controlled buffer overflows in
bcm_sf2_cfp_rule_set() and bcm_sf2_cfp_rule_del() but the fix was using
CFP_NUM_RULES, which while it is correct not to overflow the bitmaps, is
not representative of what the device actually supports. Correct that by
using bcm_sf2_cfp_rule_size() instead.
The latter subtracts the number of rules by 1, so change the checks from
greater than or equal to greater than accordingly.

When the bcm_sf2 was converted into a proper platform device driver and
used the new dsa_register_switch() interface, we would still be parsing
the legacy DSA node that contained all the port information since the
platform firmware has intentionally maintained backward and forward
compatibility to client programs. Ensure that we do parse the correct
node, which is "ports" per the revised DSA binding.

commit 536fab5bf5826404534a6c271f622ad2930d9119 upstream.
We were registering our slave MDIO bus with OF and doing so with
assigning the newly created slave_mii_bus of_node to the master MDIO bus
controller node. This is a bad thing to do for a number of reasons:
- we are completely lying about the slave MII bus is arranged and yet we
still want to control which MDIO devices it probes. It was attempted
before to play tricks with the bus_mask to perform that:
https://www.spinics.net/lists/netdev/msg429420.html but the approach
was rightfully rejected
- the device_node reference counting is messed up and we are effectively
doing a double probe on the devices we already probed using the
master, this messes up all resources reference counts (such as clocks)
The proper fix for this as indicated by David in his reply to the
thread above is to use a platform data style registration so as to
control exactly which devices we probe:
https://www.spinics.net/lists/netdev/msg430083.html
By using mdiobus_register(), our slave_mii_bus->phy_mask value is used
as intended, and all the PHY addresses that must be redirected towards
our slave MDIO bus is happening while other addresses get redirected
towards the master MDIO bus.

The 6390 family uses an extended register to set the port connected to

the priority of the frames as they pass through the switch, what
egress queue they should use, etc. Since frames being set to the CPU
are typically management frames, BPDU, IGMP, ARP, etc set the priority
to 7, the reset default, and the highest.

commit af580ae2dcb250719857b4b7024bd4bb0c2e05fb upstream.
The purpose here is to avoid ptp4l fail due to this condition:
timed out while polling for tx timestamp
increasing tx_timestamp_timeout may correct this issue, but it is likely caused by a driver bug
port 1: send peer delay request failed
So either reset the switch before the management frame was sent, or
after it was timestamped as well, but not in the middle.
The condition may arise either due to a true timeout (i.e. because
re-uploading the static config takes time), or due to the TX timestamp
actually getting lost due to reset. For the former we can increase
tx_timestamp_timeout in userspace, for the latter we need this patch.
Locking all traffic during switch reset does not make sense at all,
though. Forcing all CPU-originated traffic to potentially block waiting
for a sleepable context to send > 800 bytes over SPI is not a good idea.
Flows that are autonomously forwarded by the switch will get dropped
anyway during switch reset no matter what. So just let all other
CPU-originated traffic be dropped as well.

commit 5fc0f21246e50afdf318b5a3a941f7f4f57b8947 upstream.
Since it became possible for the DSA core to use a CPU port different
than 8, our bcm_sf2_imp_setup() function was broken because it assumes
that registers are applicable to port 8. In particular, the port's MAC
is going to stay disabled, so make sure we clear the RX_DIS and TX_DIS
bits if we are not configured for port 8.

The QCA8K family supports up to 7 ports. So use the existing

operations with the switch ports.
This was not an issue until commit 0394a63acfe2 ("net: dsa: enable and

[ Upstream commit e8521e53cca584ddf8ec4584d3c550a6c65f88c4 ]
There has been some confusion between the port number and
the VLAN ID in this driver. What we need to check for
validity is the VLAN ID, nothing else.
The current confusion came from assigning a few default
VLANs for default routing and we need to rewrite that
properly.
Instead of checking if the port number is a valid VLAN
ID, check the actual VLAN IDs passed in to the callback
one by one as expected.

[ Upstream commit af7cd0366ee994e8b35985d407261dc0ed9dfb4d ]
PHYLIB and PHYLINK handle fixed-link interfaces differently. PHYLIB
wraps them in a software PHY ("pseudo fixed link") phydev construct such
that .adjust_link driver callbacks see an unified API. Whereas PHYLINK
simply creates a phylink_link_state structure and passes it to
.mac_config.
At the time the driver was introduced, DSA was using PHYLIB for the
CPU/cascade ports (the ones with no net devices) and PHYLINK for
everything else.
As explained below:
commit aab9c4067d2389d0adfc9c53806437df7b0fe3d5
Author: Florian Fainelli <f.fainelli@gmail.com>
Date: Thu May 10 13:17:36 2018 -0700
net: dsa: Plug in PHYLINK support
Drivers that utilize fixed links for user-facing ports (e.g: bcm_sf2)
will need to implement phylink_mac_ops from now on to preserve
functionality, since PHYLINK *does not* create a phy_device instance
for fixed links.
In the above patch, DSA guards the .phylink_mac_config callback against
a NULL phydev pointer. Therefore, .adjust_link is not called in case of
a fixed-link user port.
This patch fixes the situation by converting the driver from using
.adjust_link to .phylink_mac_config. This can be done now in a unified
fashion for both slave and CPU/cascade ports because DSA now uses
PHYLINK for all ports.

We get this regression when using RTL8366RB as part of a bridge

realtek-smi switch lan0: failed to initialize vlan filtering on this port
This is because it is trying to disable VLAN filtering
on VLAN0, as we have forgot to add 1 to the port number
to get the right VLAN in rtl8366_vlan_filtering(): when
we initialize the VLAN we associate VLAN1 with port 0,
VLAN2 with port 1 etc, so we need to add 1 to the port
offset.

The hardware values for link speed are held in the sja1105_speed_t enum.
However they do not increase in the order that sja1105_get_speed_cfg was
iterating over them (basically from SJA1105_SPEED_AUTO - 0 - to
SJA1105_SPEED_1000MBPS - 1 - skipping the other two).
Another bug is that the code in sja1105_adjust_port_config relies on the
fact that an invalid link speed is detected by sja1105_get_speed_cfg and
returned as -EINVAL. However storing this into an enum that only has
positive members will cast it into an unsigned value, and it will miss
the negative check.
So take the simplest approach and remove the sja1105_get_speed_cfg
function and replace it with a simple switch-case statement.

When non-bridged, non-vlan'ed mv88e6xxx port is moving down, error
message is logged:
failed to kill vid 0081/0 for device eth_cu_1000_4
This is caused by call from __vlan_vid_del() with vin set to zero, over
call chain this results into _mv88e6xxx_port_vlan_del() called with
vid=0, and mv88e6xxx_vtu_get() called from there returns -EINVAL.
On symmetric path moving port up, call goes through
mv88e6xxx_port_vlan_prepare() that calls mv88e6xxx_port_check_hw_vlan()
that returns -EOPNOTSUPP for zero vid.
This patch changes mv88e6xxx_vtu_get() to also return -EOPNOTSUPP for
