commit d44238d8254a36249d576c96473269dbe500f5e4 upstream.
I have a ASUS PN51 S mini pc that has two xhci devices. One from AMD,
and other from ASMEDIA. The one from ASMEDIA have problems when resume
from suspend, and keep broken until unplug the power cord. I use this
kernel parameter: xhci-hcd.quirks=128 and then it works ok. I make a
path to reset only the ASMEDIA xhci.

This patch leads to passing 0 to simple_read_from_buffer()
as a fifth argument, turning the read method into a nop.
The change is fundamentally flawed, as it breaks the driver.

Some Plantronics headset as the below send an unexcept opposite
volume key's HID report for each volume key press after 200ms, like
unecepted Volume Up Key following Volume Down key pressed by user.
This patch adds a quirk to hid-plantronics for these devices, which
will ignore the second unexcepted opposite volume key if it happens
within 220ms from the last one that was handled.
Plantronics EncorePro 500 Series (047f:431e)
Plantronics Blackwire_3325 Series (047f:430c)
The patch was tested on the mentioned model, it shouldn't affect
other models, however, this quirk might be needed for them too.
Auto-repeat (when a key is held pressed) is not affected per test
result.

[ Upstream commit 40867d74c374b235e14d839f3a77f26684feefe5 ]
The fundamental premise of VRF and l3mdev core code is binding a socket
to a device (l3mdev or netdev with an L3 domain) to indicate L3 scope.
Legacy code resets flowi_oif to the l3mdev losing any original port
device binding. Ben (among others) has demonstrated use cases where the
original port device binding is important and needs to be retained.
This patch handles that by adding a new entry to the common flow struct
that can indicate the l3mdev index for later rule and table matching
avoiding the need to reset flowi_oif.
In addition to allowing more use cases that require port device binds,
this patch brings a few datapath simplications:
1. l3mdev_fib_rule_match is only called when walking fib rules and
always after l3mdev_update_flow. That allows an optimization to bail
early for non-VRF type uses cases when flowi_l3mdev is not set. Also,
only that index needs to be checked for the FIB table id.
2. l3mdev_update_flow can be called with flowi_oif set to a l3mdev
(e.g., VRF) device. By resetting flowi_oif only for this case the
FLOWI_FLAG_SKIP_NH_OIF flag is not longer needed and can be removed,
removing several checks in the datapath. The flowi_iif path can be
simplified to only be called if the it is not loopback (loopback can
not be assigned to an L3 domain) and the l3mdev index is not already
set.
3. Avoid another device lookup in the output path when the fib lookup
returns a reject failure.
Note: 2 functional tests for local traffic with reject fib rules are
updated to reflect the new direct failure at FIB lookup time for ping
rather than the failure on packet path. The current code fails like this:
HINT: Fails since address on vrf device is out of device scope
COMMAND: ip netns exec ns-A ping -c1 -w1 -I eth1 172.16.3.1
ping: Warning: source address might be selected on device other than: eth1
PING 172.16.3.1 (172.16.3.1) from 172.16.3.1 eth1: 56(84) bytes of data.
--- 172.16.3.1 ping statistics ---
1 packets transmitted, 0 received, 100% packet loss, time 0ms
where the test now directly fails:

COMMAND: ip netns exec ns-A ping -c1 -w1 -I eth1 172.16.3.1
ping: connect: No route to host

Performing a dummy read ensures that the register write operation is fully
completed, mitigating any potential bus delays that could otherwise impact
the frequency of bitbang usage. E.g., if the JTAG application uses GPIO to
control the JTAG pins (TCK, TMS, TDI, TDO, and TRST), and the application
sets the TCK clock to 1 MHz, the GPIO's high/low transitions will rely on
a delay function to ensure the clock frequency does not exceed 1 MHz.
However, this can lead to rapid toggling of the GPIO because the write
operation is POSTed and does not wait for a bus acknowledgment.

JMS_MIN_SIZE is the full ethernet frame length, while mtu is just the
data payload size. Comparing these two meant that mtus between 1500 and
1518 did not trigger enabling jumbo frames.
So instead compare the set mtu ETH_DATA_LEN, which is equal to
JMS_MIN_SIZE - ETH_HLEN - ETH_FCS_LEN;
Also do a check that the requested mtu is actually greater than the
minimum length, else we do not need to enable jumbo frames.
In practice this only introduced a very small range of mtus that did not
work properly. Newer chips allow 2000 byte large frames by default, and
older chips allow 1536 bytes long, which is equivalent to an mtu of
1514. So effectivly only mtus of 1515~1517 were broken.

There is a bug currently when there are more than one VLAN defined
and any reset that affects the PF is initiated, after the reset rebuild
no traffic will pass on any VLAN but the last one created.
This is caused by the iteration though the VLANs during replay each
clearing the vsi_map bitmap of the VSI that is being replayed. The
problem is that during rhe replay, the pointer to the vsi_map bitmap
is used by each successive vlan to determine if it should be replayed
on this VSI.
The logic was that the replay of the VLAN would replace the bit in the map
before the next VLAN would iterate through. But, since the replay copies
the old bitmap pointer to filt_replay_rules and creates a new one for the
recreated VLANS, it does not do this, and leaves the old bitmap broken
to be used to replay the remaining VLANs.
Since the old bitmap will be cleaned up in post replay cleanup, there is
no need to alter it and break following VLAN replay, so don't clear the
bit.

In rxe_comp_queue_pkt() an incoming response packet skb is enqueued to the
resp_pkts queue and then a decision is made whether to run the completer
task inline or schedule it. Finally the skb is dereferenced to bump a 'hw'
performance counter. This is wrong because if the completer task is
already running in a separate thread it may have already processed the skb
and freed it which can cause a seg fault. This has been observed
infrequently in testing at high scale.
This patch fixes this by changing the order of enqueuing the packet until
after the counter is accessed.

The issue is that before entering the crash kernel, the DWC USB controller
did not perform operations such as resetting the interrupt mask bits.
After entering the crash kernel,before the USB interrupt handler
registration was completed while loading the DWC USB driver,an GINTSTS_SOF
interrupt was received.This triggered the misroute_irq process within the
GIC handling framework,ultimately leading to the misrouting of the
interrupt,causing it to be handled by the wrong interrupt handler
and resulting in the issue.
Summary:In a scenario where the kernel triggers a panic and enters
the crash kernel,it is necessary to ensure that the interrupt mask
bit is not enabled before the interrupt registration is complete.
If an interrupt reaches the CPU at this moment,it will certainly
not be handled correctly,especially in cases where this interrupt
is reported frequently.

For i.MX7D DRAM related mux clock, the clock source change should ONLY
be done done in low level asm code without accessing DRAM, and then
calling clk API to sync the HW clock status with clk tree, it should never
touch real clock source switch via clk API, so CLK_SET_PARENT_GATE flag
should NOT be added, otherwise, DRAM's clock parent will be disabled when
DRAM is active, and system will hang.

In the switchtec_ntb_add function, it can call switchtec_ntb_init_sndev
function, then &sndev->check_link_status_work is bound with
check_link_status_work. switchtec_ntb_link_notification may be called
to start the work.
If we remove the module which will call switchtec_ntb_remove to make
cleanup, it will free sndev through kfree(sndev), while the work
mentioned above will be used. The sequence of operations that may lead
to a UAF bug is as follows:
CPU0 CPU1
| check_link_status_work
switchtec_ntb_remove |
kfree(sndev); |
| if (sndev->link_force_down)
| // use sndev
Fix it by ensuring that the work is canceled before proceeding with
the cleanup in switchtec_ntb_remove.

commit fbf8d71742557abaf558d8efb96742d442720cc2 upstream.
Calling irq_domain_remove() will lead to freeing the IRQ domain
prematurely. The domain is still referenced and will be attempted to get
used via rmi_free_function_list() -> rmi_unregister_function() ->
irq_dispose_mapping() -> irq_get_irq_data()'s ->domain pointer.
With PaX's MEMORY_SANITIZE this will lead to an access fault when
attempting to dereference embedded pointers, as in Torsten's report that
was faulting on the 'domain->ops->unmap' test.
Fix this by releasing the IRQ domain only after all related IRQs have
been deactivated.

after vqs have been created, a buggy device can send an interrupt.
A control vq callback will then try to schedule control_work which has
not been initialized yet. Similarly for config interrupt. Further, in

ports_lock which also has not been initialized.
To fix, init all locks and work before creating vqs.

The recent change to allow large frames without hardware checksumming
slotted in software checksumming in the driver if hardware could not
do it.
This will however upset TSO (TCP Segment Offloading). Typical
error dumps includes this:
skb len=2961 headroom=222 headlen=66 tailroom=0
(...)
WARNING: CPU: 0 PID: 956 at net/core/dev.c:3259 skb_warn_bad_offload+0x7c/0x108
gemini-ethernet-port: caps=(0x0000010000154813, 0x00002007ffdd7889)
And the packets do not go through.
The TSO implementation is bogus: a TSO enabled driver must propagate
the skb_shinfo(skb)->gso_size value to the TSO engine on the NIC.
Drop the size check and TSO offloading features for now: this
needs to be fixed up properly.
After this ethernet works fine on Gemini devices with a direct connected
PHY such as D-Link DNS-313.
Also tested to still be working with a DSA switch using the Gemini
ethernet as conduit interface.

commit 221af82f606d928ccef19a16d35633c63026f1be upstream.
Since commit 3f8ca2e115e5 ("vhost/scsi: Extract common handling code
from control queue handler") a null pointer dereference bug can be
triggered when guest sends an SCSI AN request.
In vhost_scsi_ctl_handle_vq(), `vc.target` is assigned with
`&v_req.tmf.lun[1]` within a switch-case block and is then passed to
vhost_scsi_get_req() which extracts `vc->req` and `tpg`. However, for
a `VIRTIO_SCSI_T_AN_*` request, tpg is not required, so `vc.target` is
set to NULL in this branch. Later, in vhost_scsi_get_req(),
`vc->target` is dereferenced without being checked, leading to a null
pointer dereference bug. This bug can be triggered from guest.
When this bug occurs, the vhost_worker process is killed while holding
`vq->mutex` and the corresponding tpg will remain occupied
indefinitely.

The RK3066 VOP sets a dma_stop bit when it's done scanning out a frame
and needs the driver to acknowledge that by clearing the bit.
Unless we clear it "between" frames, the RGB output only shows noise
instead of the picture. atomic_flush is the place for it that least
affects other code (doing it on vblank would require converting all
other usages of the reg_lock to spin_(un)lock_irq, which would affect
performance for everyone).
This seems to be a redundant synchronization mechanism that was removed
