airo: Fix read overflows sending packets

2020-06-07T09:33:02+00:00

commit 11e7a91994c29da96d847f676be023da6a2c1359 upstream.

The problem is that we always copy a minimum of ETH_ZLEN (60) bytes from
skb->data even when skb->len is less than ETH_ZLEN so it leads to a read
overflow.

The fix is to pad skb->data to at least ETH_ZLEN bytes.

net: dsa: mt7530: set CPU port to fallback mode

2020-06-07T09:33:01+00:00

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.

mt76: mt76x02u: Add support for newer versions of the XBox One wifi adapter

2020-06-07T09:32:59+00:00

commit b2934279c3e9719145ff4090d4ab951e340df17e upstream.

The current version has a new USB ID and reports as an 0x7632 device.
Adding the IDs results in it working out of the box.

p54usb: add AirVasT USB stick device-id

2020-06-07T09:32:58+00:00

commit 63e49a9fdac1b4e97ac26cb3fe953f210d83bc53 upstream.

This patch adds the AirVasT USB wireless devices 124a:4026
to the list of supported devices. It's using the ISL3886
usb firmware. Without this modification, the wiki adapter
is not recognized.

drivers/net/ibmvnic: Update VNIC protocol version reporting

2020-05-30T00:20:59+00:00

VNIC protocol version is reported in big-endian format, but it
is not byteswapped before logging. Fix that, and remove version
comparison as only one protocol version exists at this time.

net/mlx5e: replace EINVAL in mlx5e_flower_parse_meta()

2020-05-29T20:07:54+00:00

The drivers reports EINVAL to userspace through netlink on invalid meta
match. This is confusing since EINVAL is usually reserved for malformed
netlink messages. Replace it by more meaningful codes.

net/mlx5e: Fix MLX5_TC_CT dependencies

2020-05-29T20:07:54+00:00

Change MLX5_TC_CT config dependencies to include MLX5_ESWITCH instead of
MLX5_CORE_EN && NET_SWITCHDEV, which are already required by MLX5_ESWITCH.
Without this change mlx5 fails to compile if user disables MLX5_ESWITCH
without also manually disabling MLX5_TC_CT.

net/mlx5e: Properly set default values when disabling adaptive moderation

2020-05-29T20:07:53+00:00

Add a call to mlx5e_reset_rx/tx_moderation() when enabling/disabling
adaptive moderation, in order to select the proper default values.

In order to do so, we separate the logic of selecting the moderation values
and setting moderion mode (CQE/EQE based).

net/mlx5e: Fix arch depending casting issue in FEC

2020-05-29T20:07:53+00:00

Change type of active_fec to u32 to match the type expected by
mlx5e_get_fec_mode. Copy active_fec and configured_fec values to
unsigned long before preforming bitwise manipulations.
Take the same approach when configuring FEC over 50G link modes: copy
the policy into an unsigned long and only than preform bitwise
operations.

net/mlx5e: Remove warning "devices are not on same switch HW"

2020-05-29T20:07:53+00:00

On tunnel decap rule insertion, the indirect mechanism will attempt to
offload the rule on all uplink representors which will trigger the
"devices are not on same switch HW, can't offload forwarding" message
for the uplink which isn't on the same switch HW as the VF representor.

The above flow is valid and shouldn't cause warning message,
fix by removing the warning and only report this flow using extack.
