rtl_rx() and rtl_tx() are called only if the respective bits are set
in the interrupt status register. Under high load NAPI may not be
able to process all data (work_done == budget) and it will schedule
subsequent calls to the poll callback.
rtl_ack_events() however resets the bits in the interrupt status
register, therefore subsequent calls to rtl8169_poll() won't call
rtl_rx() and rtl_tx() - chip interrupts are still disabled.
Fix this by calling rtl_rx() and rtl_tx() independent of the bits
set in the interrupt status register. Both functions will detect
if there's nothing to do for them.

This fixes a general protection fault, caused by accessing the contents
of a flip_done completion object that has already been freed. It occurs
due to the preemption of a non-blocking commit worker thread W by
another commit thread X. X continues to clear its atomic state at the
end, destroying the CRTC commit object that W still needs. Switching
back to W and accessing the commit objects then leads to bad results.
Worker W becomes preemptable when waiting for flip_done to complete. At
this point, a frequently occurring commit thread X can take over. Here's
an example where W is a worker thread that flips on both CRTCs, and X
does a legacy cursor update on both CRTCs:
...
1. W does flip work
2. W runs commit_hw_done()
3. W waits for flip_done on CRTC 1
4. > flip_done for CRTC 1 completes
5. W finishes waiting for CRTC 1
6. W waits for flip_done on CRTC 2
7. > Preempted by X
8. > flip_done for CRTC 2 completes
9. X atomic_check: hw_done and flip_done are complete on all CRTCs
10. X updates cursor on both CRTCs
11. X destroys atomic state
12. X done
13. > Switch back to W
14. W waits for flip_done on CRTC 2
15. W raises general protection fault
The error looks like so:
general protection fault: 0000 [#1] PREEMPT SMP PTI

Note that i915 has this issue masked, since hw_done is signaled after
waiting for flip_done. Doing so will block the cursor update from
happening until hw_done is signaled, preventing the cursor commit from
destroying the state.
v2: The reference on the commit object needs to be obtained before
hw_done() is signaled, since that's the point where another commit
is allowed to modify the state. Assuming that the
new_crtc_state->commit object still exists within flip_done() is
incorrect.
Fix by getting a reference in setup_commit(), and releasing it
during default_clear().

Commit 713a98d90c5e ("virtio-net: serialize tx routine during reset")
introduces netif_tx_disable() after netif_device_detach() in order to
avoid use-after-free of tx queues. However, there are two issues.
1) Its operation is redundant with netif_device_detach() in case the
interface is running.
2) In case of the interface is not running before suspending and
resuming, the tx does not get resumed by netif_device_attach().
This results in losing network connectivity.
It is better to use netif_tx_lock_bh()/netif_tx_unlock_bh() instead for
serializing tx routine during reset. This also preserves the symmetry
of netif_device_detach() and netif_device_attach().

When the switch driver (e.g., mlxsw_spectrum) determines it needs to
flash a new firmware version it resets the ASIC after the flashing
process. The bus driver (e.g., mlxsw_pci) then registers itself again
with mlxsw_core which means (among other things) that the device
registers itself again with the hwmon subsystem again.
Since the device was registered with the hwmon subsystem using
devm_hwmon_device_register_with_groups(), then the old hwmon device
(registered before the flashing) was never unregistered and was
referencing stale data, resulting in a use-after free.
Fix by removing reliance on device managed APIs in mlxsw_hwmon_init().

pin_index can be indirectly controlled by user-space, hence leading

This issue was detected with the help of Smatch:

Fix this by sanitizing pin_index before using it to index

function ptp_set_pinfunc(), in which it is used to index
info->pin_config.

to kill the speculation on the first load and not worry if it can be

Clang currently warns:
drivers/net/ethernet/qlogic/qla3xxx.c:384:24: warning: signed shift
result (0xF00000000) requires 37 bits to represent, but 'int' only has
32 bits [-Wshift-overflow]
((ISP_NVRAM_MASK << 16) | qdev->eeprom_cmd_data));
~~~~~~~~~~~~~~ ^ ~~
1 warning generated.
The warning is certainly accurate since ISP_NVRAM_MASK is defined as
(0x000F << 16) which is then shifted by 16, resulting in 64424509440,
well above UINT_MAX.
Given that this is the only location in this driver where ISP_NVRAM_MASK
is shifted again, it seems likely that ISP_NVRAM_MASK was originally
defined without a shift and during the move of the shift to the
definition, this statement wasn't properly removed (since ISP_NVRAM_MASK
is used in the statenent right above this). Only the maintainers can
confirm this since this statment has been here since the driver was
first added to the kernel.

Commit 7a68d9fb8510 ("USB: usbdevfs: sanitize flags more") checks the
transfer flags for URBs submitted from userspace via usbfs. However,
the check for whether the USBDEVFS_URB_SHORT_NOT_OK flag should be
allowed for a control transfer was added in the wrong place, before
the code has properly determined the direction of the control
transfer. (Control transfers are special because for them, the
direction is set by the bRequestType byte of the Setup packet rather
than direction bit of the endpoint address.)
This patch moves code which sets up the allow_short flag for control
transfers down after is_in has been set to the correct value.

Commit db65f35f50e0 ("net: fec: add support of ethtool get_regs") introduce
ethool "--register-dump" interface to dump all FEC registers.
But not all silicon implementations of the Freescale FEC hardware module
have the FRBR (FIFO Receive Bound Register) and FRSR (FIFO Receive Start
Register) register, so we should not be trying to dump them on those that
don't.
To fix it we create a quirk flag, FEC_QUIRK_HAS_RFREG, and check it before
dump those RX FIFO registers.

On GENETv5, there is a hardware issue which prevents the GENET hardware
from generating a link UP interrupt when the link is operating at
10Mbits/sec. Since we do not have any way to configure the link
detection logic, fallback to polling in that case.

Originally, we have an issue where r8169 MSI-X interrupt is broken after
S3 suspend/resume on RTL8106e of ASUS X441UAR.

We found the all of the values in PCI BAR=4 of the ethernet adapter
become 0xFF after system resumes. That breaks the MSI-X interrupt.
Therefore, we can only fall back to MSI interrupt to fix the issue at
that time.
However, there is a commit which resolves the drivers getting nothing in
PCI BAR=4 after system resumes. It is 04cb3ae895d7 "PCI: Reprogram
bridge prefetch registers on resume" by Daniel Drake.
After apply the patch, the ethernet adapter works fine before suspend
and after resume. So, we can revert the workaround after the commit
"PCI: Reprogram bridge prefetch registers on resume" is merged into main
tree.
This patch reverts commit 7bb05b85bc2d1a1b647b91424b2ed4a18e6ecd81
"r8169: don't use MSI-X on RTL8106e".

It doesn't make sense for a perf event to be configured as a CHAIN event
in isolation, so extend the arm_pmu structure with a ->filter_match()
function to allow the backend PMU implementation to reject CHAIN events
early.
