1) New index member of struct rxe_queue was introduced but not zeroed so
the initial value of index may be random.
2) The current index is not masked off to index_mask.
In this case producer_addr() and consumer_addr() will get an invalid
address by the random index and then accessing the invalid address
triggers the following panic:
"BUG: unable to handle page fault for address: ffff9ae2c07a1414"
Fix the issue by using kzalloc() to zero out index member.

schedule_delayed_work does not push back the work if it was already
scheduled before, so amdgpu_device_delay_enable_gfx_off ran ~100 ms
after the first time GFXOFF was disabled and re-enabled, even if GFXOFF
was disabled and re-enabled again during those 100 ms.
This resulted in frame drops / stutter with the upcoming mutter 41
release on Navi 14, due to constantly enabling GFXOFF in the HW and
disabling it again (for getting the GPU clock counter).
To fix this, call cancel_delayed_work_sync when the disable count
transitions from 0 to 1, and only schedule the delayed work on the
reverse transition, not if the disable count was already 0. This makes
sure the delayed work doesn't run at unexpected times, and allows it to
be lock-free.
v2:
* Use cancel_delayed_work_sync & mutex_trylock instead of
mod_delayed_work.
v3:
* Make amdgpu_device_delay_enable_gfx_off lock-free (Christian König)
v4:
* Fix race condition between amdgpu_gfx_off_ctrl incrementing
adev->gfx.gfx_off_req_count and amdgpu_device_delay_enable_gfx_off
checking for it to be 0 (Evan Quan)

The devlink dev info command reports version information about the
device and firmware running on the board. This includes the "board.id"
field which is supposed to represent an identifier of the board design.
The ice driver uses the Product Board Assembly identifier for this.
In some cases, the PBA is not present in the NVM. If this happens,
devlink dev info will fail with an error. Instead, modify the
ice_info_pba function to just exit without filling in the context
buffer. This will cause the board.id field to be skipped. Log a dev_dbg
message in case someone wants to confirm why board.id is not showing up
for them.

rxe_mcast_add_grp_elem() in rxe_mcast.c calls rxe_alloc() while holding
spinlocks which in turn calls kzalloc(size, GFP_KERNEL) which is
incorrect. This patch replaces rxe_alloc() by rxe_alloc_locked() which
uses GFP_ATOMIC. This bug was caused by the below mentioned commit and
failing to handle the need for the atomic allocate.

Currently dpaa2_switch_takedown has a funny name and does not do the
opposite of dpaa2_switch_init, which makes probing fail when we need to
handle an -EPROBE_DEFER.
A sketch of what dpaa2_switch_init does:
dpsw_open
dpaa2_switch_detect_features
dpsw_reset
for (i = 0; i < ethsw->sw_attr.num_ifs; i++) {
dpsw_if_disable
dpsw_if_set_stp
dpsw_vlan_remove_if_untagged
dpsw_if_set_tci
dpsw_vlan_remove_if
}
dpsw_vlan_remove
alloc_ordered_workqueue
dpsw_fdb_remove
dpaa2_switch_ctrl_if_setup
When dpaa2_switch_takedown is called from the error path of
dpaa2_switch_probe(), the control interface, enabled by
dpaa2_switch_ctrl_if_setup from dpaa2_switch_init, remains enabled,
because dpaa2_switch_takedown does not call
dpaa2_switch_ctrl_if_teardown.
Since dpaa2_switch_probe might fail due to EPROBE_DEFER of a PHY, this
means that a second probe of the driver will happen with the control
interface directly enabled.
This will trigger a second error:
[ 93.273528] fsl_dpaa2_switch dpsw.0: dpsw_ctrl_if_set_pools() failed
[ 93.281966] fsl_dpaa2_switch dpsw.0: fsl_mc_driver_probe failed: -13
[ 93.288323] fsl_dpaa2_switch: probe of dpsw.0 failed with error -13
Which if we investigate the /dev/dpaa2_mc_console log, we find out is
caused by:
[E, ctrl_if_set_pools:2211, DPMNG] ctrl_if must be disabled
So make dpaa2_switch_takedown do the opposite of dpaa2_switch_init (in
reasonable limits, no reason to change STP state, re-add VLANs etc), and
rename it to something more conventional, like dpaa2_switch_teardown.

Without this patch, ATR does not work. Receive/transmit uses queue
selection based on SW DCB hashing method.
If traffic classes are not configured for PF, then use
netdev_pick_tx function for selecting queue for packet transmission.
Instead of calling i40e_swdcb_skb_tx_hash, call netdev_pick_tx,
which ensures that packet is transmitted/received from CPU that is
running the application.
Reproduction steps:
1. Load i40e driver
2. Map each MSI interrupt of i40e port for each CPU
3. Disable ntuple, enable ATR i.e.:
ethtool -K $interface ntuple off
ethtool --set-priv-flags $interface flow-director-atr
4. Run application that is generating traffic and is bound to a
single CPU, i.e.:
taskset -c 9 netperf -H 1.1.1.1 -t TCP_RR -l 10
5. Observe behavior:
Application's traffic should be restricted to the CPU provided in
taskset.

Two legacy PCI sysfs objects "legacy_io" and "legacy_mem" were updated
to use an unified address space in the commit 636b21b50152 ("PCI: Revoke
mappings like devmem"). This allows for revocations to be managed from
a single place when drivers want to take over and mmap() a /dev/mem
range.
Following the update, both of the sysfs objects should leverage the
iomem_get_mapping() function to get an appropriate address range, but
only the "legacy_io" has been correctly updated - the second attribute
seems to be using a wrong variable to pass the iomem_get_mapping()
function to.
Thus, correct the variable name used so that the "legacy_mem" sysfs
object would also correctly call the iomem_get_mapping() function.

The Renoir XHCI controller apparently doesn't resume reliably with the
standard D3hot-to-D0 delay. Increase it to 20ms.
[Alex: I talked to the AMD USB hardware team and the AMD Windows team and
they are not aware of any HW errata or specific issues. The HW works fine
in Windows. I was told Windows uses a rather generous default delay of

kmalloc_array() is called to allocate memory for tx->descp. If it fails,
the function __sdma_txclean() is called:
__sdma_txclean(dd, tx);
However, in the function __sdma_txclean(), tx-descp is dereferenced if
tx->num_desc is not zero:
sdma_unmap_desc(dd, &tx->descp[0]);
To fix this possible null-pointer dereference, assign the return value of
kmalloc_array() to a local variable descp, and then assign it to tx->descp
if it is not NULL. Otherwise, go to enomem.

Currently we are unable to ping a bridge on top of a felix switch which
uses the ocelot-8021q tagger. The packets are dropped on the ingress of
the user port and the 'drop_local' counter increments (the counter which
denotes drops due to no valid destinations).
Dumping the PGID tables, it becomes clear that the PGID_SRC of the user
port is zero, so it has no valid destinations.
But looking at the code, the cpu_fwd_mask (the bit mask of DSA tag_8021q
ports) is clearly missing from the forwarding mask of ports that are
under a bridge. So this has always been broken.
Looking at the version history of the patch, in v7
https://patchwork.kernel.org/project/netdevbpf/patch/20210125220333.1004365-12-olteanv@gmail.com/
the code looked like this:
/* Standalone ports forward only to DSA tag_8021q CPU ports */
unsigned long mask = cpu_fwd_mask;
(...)
} else if (ocelot->bridge_fwd_mask & BIT(port)) {
mask |= ocelot->bridge_fwd_mask & ~BIT(port);
while in v8 (the merged version)
https://patchwork.kernel.org/project/netdevbpf/patch/20210129010009.3959398-12-olteanv@gmail.com/
it looked like this:
unsigned long mask;
(...)
} else if (ocelot->bridge_fwd_mask & BIT(port)) {
mask = ocelot->bridge_fwd_mask & ~BIT(port);
So the breakage was introduced between v7 and v8 of the patch.

Commit a20dcf53ea98 ("usb: typec: tcpm: Respond Not_Supported if no
snk_vdo"), stops tcpm_pd_data_request() calling tcpm_handle_vdm_request()
when port->nr_snk_vdo is not set. But the VDM might be intended for an
altmode-driver, in which case nr_snk_vdo does not matter.
This change breaks the forwarding of connector hotplug (HPD) events
for displayport altmode on devices which don't set nr_snk_vdo.
tcpm_pd_data_request() is the only caller of tcpm_handle_vdm_request(),
so we can move the nr_snk_vdo check to inside it, at which point we
have already looked up the altmode device so we can check for this too.
Doing this check here also ensures that vdm_state gets set to
VDM_STATE_DONE if it was VDM_STATE_BUSY, even if we end up with
responding with PD_MSG_CTRL_NOT_SUPP later.
Note that tcpm_handle_vdm_request() was already sending
PD_MSG_CTRL_NOT_SUPP in some circumstances, after moving the nr_snk_vdo
check the same error-path is now taken when that check fails. So that
we have only one error-path for this and not two. Replace the
tcpm_queue_message(PD_MSG_CTRL_NOT_SUPP) used by the existing error-path
with the more robust tcpm_pd_handle_msg() from the (now removed) second
error-path.

This fixes improper iotlb invalidation in intel_pasid_tear_down_entry().
When a PASID was used as nested mode, released and reused, the following
error message will appear:
[ 180.187556] Unexpected page request in Privilege Mode
[ 180.187565] Unexpected page request in Privilege Mode
[ 180.279933] Unexpected page request in Privilege Mode
[ 180.279937] Unexpected page request in Privilege Mode
Per chapter 6.5.3.3 of VT-d spec 3.3, when tear down a pasid entry, the
software should use Domain selective IOTLB flush if the PGTT of the pasid
entry is SL only or Nested, while for the pasid entries whose PGTT is FL
only or PT using PASID-based IOTLB flush is enough.

A PASID reference is increased whenever a device is bound to an mm (and
its PASID) successfully (i.e. the device's sdev user count is increased).
But the reference is not dropped every time the device is unbound
successfully from the mm (i.e. the device's sdev user count is decreased).
The reference is dropped only once by calling intel_svm_free_pasid() when
there isn't any device bound to the mm. intel_svm_free_pasid() drops the
reference and only frees the PASID on zero reference.
Fix the issue by dropping the PASID reference and freeing the PASID when
no reference on successful unbinding the device by calling
intel_svm_free_pasid() .

Syzbot reported uninit-value in asix_mdio_read(). The problem was in
missing error handling. asix_read_cmd() should initialize passed stack
variable smsr, but it can fail in some cases. Then while condidition
checks possibly uninit smsr variable.
Since smsr is uninitialized stack variable, driver can misbehave,
because smsr will be random in case of asix_read_cmd() failure.
Fix it by adding error handling and just continue the loop instead of
checking uninit value.
Added helper function for checking Host_En bit, since wrong loop was used
in 4 functions and there is no need in copy-pasting code parts.

When registering mdiobus children, if we get an -EPROBE_DEFER, we shouldn't
ignore it and continue registering the rest of the mdiobus children. This
would permanently prevent the deferring child mdiobus from working instead
of reattempting it in the future. So, if a child mdiobus needs to be
reattempted in the future, defer the entire mdio-mux initialization.
This fixes the issue where PHYs sitting under the mdio-mux aren't
initialized correctly if the PHY's interrupt controller is not yet ready
when the mdio-mux is being probed. Additional context in the link below.
