commit e5c23779f93d45e39a52758ca593bd7e62e9b4be upstream.
In the case where there is only a cycle counter available (i.e.
PMCR_EL0.N is 0) and an event other than CPU cycles is opened, the open
should fail as the event can never possibly be scheduled. However, the
event validation when an event is opened is skipped when the group
leader is opened. Fix this by always validating the group leader events.

commit 04ebaa1cfddae5f240cc7404f009133bb0389a47 upstream.
When we decode the latency and the max_latency, u16 value may not fit
the required size and could lead to the wrong LTR representation.
Scaling is represented as:
scale 0 - 1 (2^(5*0)) = 2^0
scale 1 - 32 (2^(5 *1))= 2^5
scale 2 - 1024 (2^(5 *2)) =2^10
scale 3 - 32768 (2^(5 *3)) =2^15
scale 4 - 1048576 (2^(5 *4)) = 2^20
scale 5 - 33554432 (2^(5 *4)) = 2^25
scale 4 and scale 5 required 20 and 25 bits respectively.
scale 6 reserved.
Replace the u16 type with the u32 type and allow corrected LTR
representation.

[ Upstream commit 3d0b93d92a2790337aa9d18cb332d02356a24126 ]
If the device is already in a runtime PM enabled state
pm_runtime_get_sync() will return 1.
Also, we need to call pm_runtime_put_noidle() when pm_runtime_get_sync()
fails, so use pm_runtime_resume_and_get() instead. this function
will handle this.

commit 206680c4e46b62fd8909385e0874a36952595b85 upstream.
The bug is here:
__func__, desc, &desc->tx_dma_desc.phys, ret, cookie, residue);
The list iterator 'desc' will point to a bogus position containing
HEAD if the list is empty or no element is found. To avoid dev_dbg()
prints a invalid address, use a new variable 'iter' as the list
iterator, while use the origin variable 'desc' as a dedicated
pointer to point to the found element.

commit aafa9f958342db36c17ac2a7f1b841032c96feb4 upstream.
Before detecting the cable type on the dma bar, the driver should check
whether the 'bmdma_addr' is zero, which means the adapter does not
support DMA, otherwise we will get the following error:

[ Upstream commit 857b06527f707f5df634b854898a191b5c1d0272 ]
We set the qedi_ep state to EP_STATE_OFLDCONN_START when the ep is
created. Then in qedi_set_path we kick off the offload work. If userspace
times out the connection and calls ep_disconnect, qedi will only flush the
offload work if the qedi_ep state has transitioned away from
EP_STATE_OFLDCONN_START. If we can't connect we will not have transitioned
state and will leave the offload work running, and we will free the qedi_ep
from under it.
This patch just has us init the work when we create the ep, then always
flush it.

[ Upstream commit 5ad7f18cd82cee8e773d40cc7a1465a526f2615c ]
commit 4298388574da ("net: macb: restart tx after tx used bit read")
added support for restarting transmission. Restarting tx does not work
in case controller asserts TXUBR interrupt and TQBP is already at the end
of the tx queue. In that situation, restarting tx will immediately cause
assertion of another TXUBR interrupt. The driver will end up in an infinite
interrupt loop which it cannot break out of.
For cases where TQBP is at the end of the tx queue, instead
only clear TX_USED interrupt. As more data gets pushed to the queue,
transmission will resume.
This issue was observed on a Xilinx Zynq-7000 based board.
During stress test of the network interface,
driver would get stuck on interrupt loop within seconds or minutes
causing CPU to stall.

[ Upstream commit 047ae665577776b7feb11bd4f81f46627cff95e7 ]
kzalloc() is a memory allocation function which can return NULL when
some internal memory errors happen. So it is better to check it to
prevent potential wrong memory access.
Besides, since mdp5_plane_reset() is void type, so we should better
set `plane-state` to NULL after releasing it.

commit bd8963e602c77adc76dbbbfc3417c3cf14fed76b upstream.
Wait for completion of write transfers before returning from the driver.
At first sight it may seem advantageous to leave write transfers queued
for the controller to carry out on its own time, but there's a couple of
issues with it:
* Driver doesn't check for FIFO space.
* The queued writes can complete while the driver is in its I2C read
transfer path which means it will get confused by the raising of
XEN (the 'transaction ended' signal). This can cause a spurious
ENODATA error due to premature reading of the MRXFIFO register.
Adding the wait fixes some unreliability issues with the driver. There's
some efficiency cost to it (especially with pasemi_smb_waitready doing
its polling), but that will be alleviated once the driver receives
interrupt support.

commit 08c1af8f1c13bbf210f1760132f4df24d0ed46d6 upstream.
It is possible to set up dm-integrity in such a way that the
"tag_size" parameter is less than the actual digest size. In this
situation, a part of the digest beyond tag_size is ignored.
In this case, dm-integrity would write beyond the end of the
ic->recalc_tags array and corrupt memory. The corruption happened in
integrity_recalc->integrity_sector_checksum->crypto_shash_final.
Fix this corruption by increasing the tags array so that it has enough
padding at the end to accomodate the loop in integrity_recalc() being
able to write a full digest size for the last member of the tags
array.

commit e4f1541caf60fcbe5a59e9d25805c0b5865e546a upstream.
"Pre-multiplied" is the default pixel blend mode for KMS/DRM, as
documented in supported_modes of drm_plane_create_blend_mode_property():
https://cgit.freedesktop.org/drm/drm-misc/tree/drivers/gpu/drm/drm_blend.c
In this mode, both 'pixel alpha' and 'plane alpha' participate in the
calculation, as described by the pixel blend mode formula in KMS/DRM
documentation:
out.rgb = plane_alpha * fg.rgb +
(1 - (plane_alpha * fg.alpha)) * bg.rgb
Considering the blend config mechanisms we have in the driver so far,
the alpha mode that better fits this blend mode is the
_PER_PIXEL_ALPHA_COMBINED_GLOBAL_GAIN, where the value for global_gain
is the plane alpha (global_alpha).
With this change, alpha property stops to be ignored. It also addresses
Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1734
v2:
* keep the 8-bit value for global_alpha_value (Nicholas)
* correct the logical ordering for combined global gain (Nicholas)
* apply to dcn10 too (Nicholas)

commit 5a6b06f5927c940fa44026695779c30b7536474c upstream.
The ieee80211_tx_info_clear_status() helper also clears the rate counts and
the driver-private part of struct ieee80211_tx_info, so using it breaks
quite a few other things. So back out of using it, and instead define a
ath-internal helper that only clears the area between the
status_driver_data and the rates info. Combined with moving the
ath_frame_info struct to status_driver_data, this avoids clearing anything
we shouldn't be, and so we can keep the existing code for handling the rate
information.
While fixing this I also noticed that the setting of
tx_info->status.rates[tx_rateindex].count on hardware underrun errors was
always immediately overridden by the normal setting of the same fields, so
rearrange the code so that the underrun detection actually takes effect.
The new helper could be generalised to a 'memset_between()' helper, but
leave it as a driver-internal helper for now since this needs to go to
stable.

commit 037250f0a45cf9ecf5b52d4b9ff8eadeb609c800 upstream.
The ath9k driver was not properly clearing the status area in the
ieee80211_tx_info struct before reporting TX status to mac80211. Instead,
it was manually filling in fields, which meant that fields introduced later
were left as-is.
Conveniently, mac80211 actually provides a helper to zero out the status
area, so use that to make sure we zero everything.
The last commit touching the driver function writing the status information
seems to have actually been fixing an issue that was also caused by the
area being uninitialised; but it only added clearing of a single field
instead of the whole struct. That is now redundant, though, so revert that
commit and use it as a convenient Fixes tag.

[ Upstream commit ec4eb8a86ade4d22633e1da2a7d85a846b7d1798 ]
When a slip driver is detaching, the slip_close() will act to
cleanup necessary resources and sl->tty is set to NULL in
slip_close(). Meanwhile, the packet we transmit is blocked,
sl_tx_timeout() will be called. Although slip_close() and
sl_tx_timeout() use sl->lock to synchronize, we don`t judge
whether sl->tty equals to NULL in sl_tx_timeout() and the
null pointer dereference bug will happen.

| slip_close()
| spin_lock_bh(&sl->lock)

sl_tx_timeout() | spin_unlock_bh(&sl->lock)
spin_lock(&sl->lock); |

... | synchronize_rcu()
We set NULL to sl->tty in position (1) and dereference sl->tty
in position (2).
This patch adds check in sl_tx_timeout(). If sl->tty equals to
NULL, sl_tx_timeout() will goto out.

[Why]
On resume we do link detection for all non-MST connectors.
MST is handled separately. However the condition for telling
if connector is on mst branch is not enough for mst hub case.
Link detection for mst branch link leads to mst topology reset.
That causes assert in dc_link_allocate_mst_payload()
[How]
Use link type as indicator for mst link.

[ Upstream commit afb8e246527536848b9b4025b40e613edf776a9d ]
aqc111_rx_fixup() contains several out-of-bounds accesses that can be
triggered by a malicious (or defective) USB device, in particular:
- The metadata array (desc_offset..desc_offset+2*pkt_count) can be out of bounds,
causing OOB reads and (on big-endian systems) OOB endianness flips.
- A packet can overlap the metadata array, causing a later OOB
endianness flip to corrupt data used by a cloned SKB that has already
been handed off into the network stack.
- A packet SKB can be constructed whose tail is far beyond its end,
causing out-of-bounds heap data to be considered part of the SKB's
data.
Found doing variant analysis. Tested it with another driver (ax88179_178a), since
I don't have a aqc111 device to test it, but the code looks very similar.

The adapter request_limit is hardcoded to be INITIAL_SRP_LIMIT which is
currently an arbitrary value of 800. Increase this value to 1024 which
better matches the characteristics of the typical IBMi Initiator that

This change also has the secondary benefit of being a power of two as
required by the kfifo API. Since, Commit ab9bb6318b09 ("Partially revert

We need to get_page() under cmdr_lock to avoid concurrent
tcmu_blocks_release().

[ Upstream commit b6cae15b5710c8097aad26a2e5e752c323ee5348 ]
When reading a packet from a host-to-guest ring buffer, there is no
memory barrier between reading the write index (to see if there is
a packet to read) and reading the contents of the packet. The Hyper-V
host uses store-release when updating the write index to ensure that
writes of the packet data are completed first. On the guest side,
the processor can reorder and read the packet data before the write
index, and sometimes get stale packet data. Getting such stale packet
data has been observed in a reproducible case in a VM on ARM64.
Fix this by using virt_load_acquire() to read the write index,
ensuring that reads of the packet data cannot be reordered
before it. Preventing such reordering is logically correct, and
with this change, getting stale data can no longer be reproduced.

As the kmalloc_array() may return null, the 'event_waiters[i].wait' would lead to null-pointer dereference.
Therefore, it is better to check the return value of kmalloc_array() to avoid this confusion.

The member 'msm_dsi->connector' isn't assigned until
msm_dsi_manager_connector_init() returns (see msm_dsi_modeset_init() and
how it assigns the return value). Therefore this pointer is going to be
NULL here. Let's use 'connector' which is what was intended.

[ Upstream commit a6aaa00324240967272b451bfa772547bd576ee6 ]
When using a fixed-link, the altr_tse_pcs driver crashes
due to null-pointer dereference as no phy_device is provided to
tse_pcs_fix_mac_speed function. Fix this by adding a check for
phy_dev before calling the tse_pcs_fix_mac_speed() function.
Also clean up the tse_pcs_fix_mac_speed function a bit. There is
no need to check for splitter_base and sgmii_adapter_base
because the driver will fail if these 2 variables are not
derived from the device tree.
