cc2e77dddf net: dsa: b53: fix jumbo frame mtu check
[ Upstream commit 42fb3acf6826c6764ba79feb6e15229b43fd2f9f ]

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.

fba28f12ee net: phy: dp83869: fix memory corruption when enabling fiber
[ Upstream commit a842e443ca8184f2dc82ab307b43a8b38defd6a5 ]

When configuring the fiber port, the DP83869 PHY driver incorrectly
calls linkmode_set_bit() with a bit mask (1 << 10) rather than a bit
number (10). This corrupts some other memory location -- in case of
arm64 the priv pointer in the same structure.

Since the advertising flags are updated from supported at the end of the
function the incorrect line isn't needed at all and can be removed.

6bb154f4ac ice: fix VLAN replay after reset
[ Upstream commit 0eae2c136cb624e4050092feb59f18159b4f2512 ]

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.

df727900ad RDMA/rxe: Fix seg fault in rxe_comp_queue_pkt
commit 2b23b6097303ed0ba5f4bc036a1c07b6027af5c6 upstream.

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 values of the variables xres and yres are placed in strbuf.
These variables are obtained from strbuf1.
The strbuf1 array contains digit characters
and a space if the array contains non-digit characters.
Then, when executing sprintf(strbuf, "%ux%ux8", xres, yres);
more than 16 bytes will be written to strbuf.
It is suggested to increase the size of the strbuf array to 24.

5bcc565db4 usb: dwc2: Adjust the timing of USB Driver Interrupt Registration in the Crashkernel Scenario
[ Upstream commit 4058c39bd176daf11a826802d940d86292a6b02b ]

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.

Please refer to the Crashkernel dmesg information as follows
(the message on line 3 was added before devm_request_irq is

9f06c4e294 ntb: ntb_hw_switchtec: Fix use after free vulnerability in switchtec_ntb_remove due to race condition
[ Upstream commit e51aded92d42784313ba16c12f4f88cc4f973bbb ]

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.

93ce148c92 RDMA/mad: Improve handling of timed out WRs of mad agent
[ Upstream commit 2a777679b8ccd09a9a65ea0716ef10365179caac ]

Current timeout handler of mad agent acquires/releases mad_agent_priv
lock for every timed out WRs. This causes heavy locking contention
when higher no. of WRs are to be handled inside timeout handler.

This leads to softlockup with below trace in some use cases where
rdma-cm path is used to establish connection between peer nodes

382027a63c Input: synaptics-rmi4 - fix UAF of IRQ domain on driver removal
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.

098bb6f404 virtio_console: fix misc probe bugs
[ Upstream commit b9efbe2b8f0177fa97bfab290d60858900aa196b ]

This fixes the following issue discovered by code review:

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
and out vq callbacks invoke find_port_by_vq which attempts to take
ports_lock which also has not been initialized.

To fix, init all locks and work before creating vqs.

5a37f561e7 net: ethernet: cortina: Drop TSO support
[ Upstream commit ac631873c9e7a50d2a8de457cfc4b9f86666403e ]

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.

11889a0690 vhost/scsi: null-ptr-dereference in vhost_scsi_get_req()
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.

Below is the KASAN report:

c9a7d95ef5 ACPI: battery: Fix possible crash when unregistering a battery hook
[ Upstream commit 76959aff14a0012ad6b984ec7686d163deccdc16 ]

When a battery hook returns an error when adding a new battery, then
the battery hook is automatically unregistered.
However the battery hook provider cannot know that, so it will later
call battery_hook_unregister() on the already unregistered battery
hook, resulting in a crash.

Fix this by using the list head to mark already unregistered battery
hooks as already being unregistered so that they can be ignored by
battery_hook_unregister().

[ Upstream commit 6b44aa559d6c7f4ea591ef9d2352a7250138d62a ]

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
in later iterations of the VOP hardware block.

36a33fc208 drm/rockchip: support gamma control on RK3399
[ Upstream commit 7ae7a6211fe7251543796d5af971acb8c9e2da9e ]

The RK3399 has a 1024-entry gamma LUT with 10 bits per component on its
"big" VOP and a 256-entry, 8 bit per component LUT on the "little" VOP.
Compared to the RK3288, it no longer requires disabling gamma while
updating the LUT. On the RK3399, the LUT can be updated at any time as
the hardware has two LUT buffers, one can be written while the other is
in use. A swap of the buffers is triggered by writing 1 to the
update_gamma_lut register.

cafee81fda drm/rockchip: define gamma registers for RK3399
[ Upstream commit 3ba000d6ae999b99f29afd64814877a5c4406786 ]

The VOP on RK3399 has a different approach from previous versions for
setting a gamma lookup table, using an update_gamma_lut register. As
this differs from RK3288, give RK3399 its own set of "common" register
definitions.

It is not valid to call pm_runtime_set_suspended() for devices

already and working. So, call pm_runtime_disable() before to fix it.

0fdf37d1b6 gpio: davinci: fix lazy disable
commit 3360d41f4ac490282fddc3ccc0b58679aa5c065d upstream.

On a few platforms such as TI's AM69 device, disable_irq() fails to keep
track of the interrupts that happen between disable_irq() and
enable_irq() and those interrupts are missed. Use the ->irq_unmask() and
->irq_mask() methods instead of ->irq_enable() and ->irq_disable() to
correctly keep track of edges when disable_irq is called.

This solves the issue of disable_irq() not working as expected on such
platforms.

commit 675faf5a14c14a2be0b870db30a70764df81e2df upstream.

The commit b8c43360f6e4 ("net: stmmac: No need to calculate speed divider
when offload is disabled") allows the "port_transmit_rate_kbps" to be
set to a value of 0, which is then passed to the "div_s64" function when
tc-cbs is disabled. This leads to a zero-division error.

When tc-cbs is disabled, the idleslope, sendslope, and credit values the
credit values are not required to be configured. Therefore, adding a return
statement after setting the txQ mode to DCB when tc-cbs is disabled would
prevent a zero-division error.

commit ade508b545c969c72cd68479f275a5dd640fd8b9 upstream.

With PWRSTS_OFF_ON, PCIe GDSCs are turned off during gdsc_disable(). This
can happen during scenarios such as system suspend and breaks the resume
of PCIe controllers from suspend.

So use PWRSTS_RET_ON to indicate the GDSC driver to not turn off the GDSCs
during gdsc_disable() and allow the hardware to transition the GDSCs to
retention when the parent domain enters low power state during system
suspend.

commit c5a85ed88e043474161bbfe54002c89c1cb50ee2 upstream.

in venus_probe, core->work is bound with venus_sys_error_handler, which is
used to handle error. The code use core->sys_err_done to make sync work.
The core->work is started in venus_event_notify.

If we call venus_remove, there might be an unfished work. The possible
sequence is as follows:

CPU0                  CPU1

                     |venus_sys_error_handler
venus_remove         |

					 |venus_hfi_queues_reinit
                     |//use hdev

Fix it by canceling the work in venus_remove.
