commit c12296bbec upstream.
In __team_options_register, team_options are allocated and appended to
the team's option_list.
If one option instance allocation fails, the "inst_rollback" cleanup
path frees the previously allocated options but doesn't remove them from
the team's option_list.
This leaves dangling pointers that can be dereferenced later by other
parts of the team driver that iterate over options.
This patch fixes the cleanup path to remove the dangling pointers from
the list.
As far as I can tell, this uaf doesn't have much security implications
since it would be fairly hard to exploit (an attacker would need to make
the allocation of that specific small object fail) but it's still nice
to fix.

If a device sends a packet that is inbetween 0
and sizeof(u64) the value passed to skb_trim()
as length will wrap around ending up as some very
large value.
The driver will then proceed to parse the header
located at that position, which will either oops or
process some random value.
The fix is to check against sizeof(u64) rather than
0, which the driver currently does. The issue exists
since the introduction of the driver.

[ Upstream commit f24a49a375 ]
Starting with commit 4e51bf44a0 ("net: bridge: move the switchdev
object replay helpers to "push" mode") the switchdev_bridge_port_offload()
helper was extended with the intention to provide switchdev drivers easy
access to object addition and deletion replays. This works by calling
the replay helpers with non-NULL notifier blocks.
In the same commit, the dpaa2-switch driver was updated so that it
passes valid notifier blocks to the helper. At that moment, no
regression was identified through testing.
In the meantime, the blamed commit changed the behavior in terms of
which ports get hit by the replay. Before this commit, only the initial
port which identified itself as offloaded through
switchdev_bridge_port_offload() got a replay of all port objects and
FDBs. After this, the newly joining port will trigger a replay of
objects on all bridge ports and on the bridge itself.
This behavior leads to errors in dpaa2_switch_port_vlans_add() when a
VLAN gets installed on the same interface multiple times.
The intended mechanism to address this is to pass a non-NULL ctx to the
switchdev_bridge_port_offload() helper and then check it against the
port's private structure. But since the driver does not have any use for
the replayed port objects and FDBs until it gains support for LAG
offload, it's better to fix the issue by reverting the dpaa2-switch
driver to not ask for replay. The pointers will be added back when we
are prepared to ignore replays on unrelated ports.

[ Upstream commit d760117060 ]
This patch fixes two issues:
Issue 1
-------
Description
```````````
Current code does not call dma_sync_single_for_cpu() to sync data from
the device side memory to the CPU side memory before the XDP code path
uses the CPU side data.
This causes the XDP code path to read the unset garbage data in the CPU
side memory, resulting in incorrect handling of the packet by XDP.
Solution
````````
1. Add a call to dma_sync_single_for_cpu() before the XDP code starts to
use the data in the CPU side memory.
2. The XDP code verdict can be XDP_PASS, in which case there is a
fallback to the non-XDP code, which also calls
dma_sync_single_for_cpu().
To avoid calling dma_sync_single_for_cpu() twice:
2.1. Put the dma_sync_single_for_cpu() in the code in such a place where
it happens before XDP and non-XDP code.
2.2. Remove the calls to dma_sync_single_for_cpu() in the non-XDP code
for the first buffer only (rx_copybreak and non-rx_copybreak
cases), since the new call that was added covers these cases.
The call to dma_sync_single_for_cpu() for the second buffer and on
stays because only the first buffer is handled by the newly added
dma_sync_single_for_cpu(). And there is no need for special
handling of the second buffer and on for the XDP path since
currently the driver supports only single buffer packets.
Issue 2
-------
Description
```````````
In case the XDP code forwarded the packet (ENA_XDP_FORWARDED),
ena_unmap_rx_buff_attrs() is called with attrs set to 0.
This means that before unmapping the buffer, the internal function
dma_unmap_page_attrs() will also call dma_sync_single_for_cpu() on
the whole buffer (not only on the data part of it).
This sync is both wasteful (since a sync was already explicitly
called before) and also causes a bug, which will be explained
using the below diagram.
The following diagram shows the flow of events causing the bug.
The order of events is (1)-(4) as shown in the diagram.

crashing the kernel.
Solution

Explicitly tell ena_unmap_rx_buff_attrs() not to call
dma_sync_single_for_cpu() by passing it the ENA_DMA_ATTR_SKIP_CPU_SYNC
flag.

New states introduced:
IAVF_FDIR_FLTR_DIS_REQUEST
IAVF_FDIR_FLTR_DIS_PENDING
IAVF_FDIR_FLTR_INACTIVE
Current FDIR state machines (SM) are not adequate to handle a few
scenarios in the link DOWN/UP event, reset event and ntuple-feature.
For example, when VF link goes DOWN and comes back UP administratively,
the expectation is that previously installed filters should also be
restored. But with current SM, filters are not restored.
So with new SM, during link DOWN filters are marked as INACTIVE in
the iavf list but removed from PF. After link UP, SM will transition
from INACTIVE to ADD_REQUEST to restore the filter.
Similarly, with VF reset, filters will be removed from the PF, but
marked as INACTIVE in the iavf list. Filters will be restored after
reset completion.
Steps to reproduce:
-------------------
1. Create a VF. Here VF is enp8s0.
2. Assign IP addresses to VF and link partner and ping continuously
from remote. Here remote IP is 1.1.1.1.
3. Check default RX Queue of traffic.
ethtool -S enp8s0 | grep -E "rx-[[:digit:]]+\.packets"
4. Add filter - change default RX Queue (to 15 here)
ethtool -U ens8s0 flow-type ip4 src-ip 1.1.1.1 action 15 loc 5
5. Ensure filter gets added and traffic is received on RX queue 15 now.
Link event testing:
-------------------
6. Bring VF link down and up. If traffic flows to configured queue 15,
test is success, otherwise it is a failure.
Reset event testing:
--------------------
7. Reset the VF. If traffic flows to configured queue 15, test is success,
otherwise it is a failure.

We are issuing HWRM_FUNC_RESET cmd to reset the device including
all reserved resources, but not clearing the reservations
within the driver struct. As a result, when the driver re-initializes
as part of resume, it believes that there is no need to do any
resource reservation and goes ahead and tries to allocate rings
which will eventually fail beyond a certain number pre-reserved by

After calling ethtool -g it was not possible to adjust the TX ring

# ethtool -g eth1
Ring parameters for eth1:
Pre-set maximums:
RX: 4

The reason for this is that the readonly setting rx_pending get

fails regardless of the provided parameter. So fix this by accepting
the exposed RX defaults. Instead of adding another magic number

The qca_spi driver stop and restart the SPI kernel thread
(via ndo_stop & ndo_open) in case of TX ring changes. This is
a big issue because it allows userspace to prevent restart of
the SPI kernel thread (via signals). A subsequent change of
TX ring wrongly assume a valid spi_thread pointer which result
in a crash.
So prevent this by stopping the network traffic handling and

In such a case, the comparing function should return false, as there is no

Furthermore, this will result in an attempt to enter switchdev mode

[ Upstream commit eab0da3891 ]
Due to the cited patch, devlink health commands take devlink lock and
this may result in deadlock for mlx5e_tx_reporter as it takes local
state_lock before calling devlink health report and on the other hand
devlink health commands such as diagnose for same reporter take local
state_lock after taking devlink lock (see kernel log below).
To fix it, remove local state_lock from mlx5e_tx_timeout_work() before
calling devlink_health_report() and take care to cancel the work before
any call to close channels, which may free the SQs that should be
handled by the work. Before cancel_work_sync(), use current_work() to
check we are not calling it from within the work, as
mlx5e_tx_timeout_work() itself may close the channels and reopen as part
of recovery flow.
While removing state_lock from mlx5e_tx_timeout_work() keep rtnl_lock to
ensure no change in netdev->real_num_tx_queues, but use rtnl_trylock()
and a flag to avoid deadlock by calling cancel_work_sync() before
closing the channels while holding rtnl_lock too.

commit 4b0768b655 upstream.
When FIFO reaches near full state, device will issue pause frame.
If pause slot is enabled(set to 1), in this time, device will issue
pause frame only once. But if pause slot is disabled(set to 0), device
will keep sending pause frames until FIFO reaches near empty state.
When pause slot is disabled, if there is no one to handle receive
packets, device FIFO will reach near full state and keep sending
pause frames. That will impact entire local area network.
This issue can be reproduced in Chromebox (not Chromebook) in
developer mode running a test image (and v5.10 kernel):
1) ping -f $CHROMEBOX (from workstation on same local network)
2) run "powerd_dbus_suspend" from command line on the $CHROMEBOX
3) ping $ROUTER (wait until ping fails from workstation)
Takes about ~20-30 seconds after step 2 for the local network to
stop working.
Fix this issue by enabling pause slot to only send pause frame once
when FIFO reaches near full state.
