[ Upstream commit 472497d0bdae890a896013332a0b673f9acdf2bf ]
If selftest and reset are performed at the same time, the phy
loopback setting may be still in enable state after the reset,
and device cannot link up. So fix this issue by disabling phy
loopback before phy_start().

[ Upstream commit b416e872be06fdace3c36cf5210130509d0f0e72 ]
Currently, netif_tx_stop_all_queues() is used to ensure that
the xmit is not running, but for the concurrent case it will
not take effect, since netif_tx_stop_all_queues() just sets
a flag without locking to indicate that the xmit queue(s)
should not be run.
So use netif_tx_disable() to replace netif_tx_stop_all_queues(),
it takes the xmit queue lock while marking the queue stopped.

[ Upstream commit 905416f18fe74bdd4de91bf94ef5a790a36e4b99 ]
When skb->ip_summed is CHECKSUM_PARTIAL, for non-tunnel udp packet,
which has a dest port as the IANA assigned, the hardware is expected
to do the checksum offload, but the hardware whose version is below
V3 will not do the checksum offload when udp dest port is 4790.
So fixes it by doing the checksum in software for this case.

[ Upstream commit b4047aac4ec1066bab6c71950623746d7bcf7154 ]
In some cases, the device is not initialized because reset failed.
If another task calls hns3_reset_notify_up_enet() before reset
retry, it will cause an error since uninitialized pointer access.
So add check for HNS3_NIC_STATE_INITED before calling
hns3_nic_net_open() in hns3_reset_notify_up_enet().

[ Upstream commit ce4f62f9dd8cf43ac044045ed598a0b80ef33890 ]
If spm_lvl is set to 0 or 1, when system suspend kicks start and HBA is
runtime active, system suspend may just bail without doing anything (the
fast path), leaving other contexts still running, e.g., clock gating and
clock scaling. When system resume kicks start, concurrency can happen
between ufshcd_resume() and these contexts, leading to various stability
issues.
Add a check against HBA's runtime state and allowing fast path only if HBA
is runtime suspended, otherwise let system suspend go ahead call
ufshcd_suspend(). This will guarantee that these contexts are stopped by
either runtime suspend or system suspend.

[ Upstream commit fcb16d9a8ecf1e9bfced0fc654ea4e2caa7517f4 ]
In a case when the initiator in P2P mode by some circumstances does not
send PRLI, the target, in a case when the target port's WWPN is less than
initiator's, changes the discovery state in DSC_GNL. When gnl completes it
sends PRLI to the initiator.
Usually the initiator in P2P mode always sends PRLI. We caught this issue
on Linux stable v5.4.6 https://www.spinics.net/lists/stable/msg458515.html.
Fix this particular corner case in the behaviour of the P2P mod target
login state machine.

[ Upstream commit 04922b7445a1950b86f130a1fe8c52cc27b3e30b ]
The char device setup and cleanup has device lifetime issues regarding when
parts are initialized and cleaned up. The initialization of struct device is
done incorrectly. device_initialize() needs to be called on the 'struct
device' and then additional changes can be added. The ->release() function
needs to be setup via device_type before dev_set_name() to allow proper
cleanup. The change re-parents the cdev under the wq->conf_dev to get
natural reference inheritance. No known dependency on the old device path exists.

There are calls to idxd_cmd_exec that pass a null status pointer however
a recent commit has added an assignment to *status that can end up
with a null pointer dereference. The function expects a null status

status is first null checked. Fix the issue by null checking status
before making the assignment.

Function qtnf_event_handle_external_auth calls memcpy without
checking the length.
A user could control that length and trigger a buffer overflow.
Fix by checking the length is within the maximum allowed size.

Fix the following out-of-bounds warnings by adding a new structure
wl3501_req instead of duplicating the same members in structure
wl3501_join_req and wl3501_scan_confirm:
arch/x86/include/asm/string_32.h:182:25: warning: '__builtin_memcpy' offset [39, 108] from the object at 'sig' is out of the bounds of referenced subobject 'beacon_period' with type 'short unsigned int' at offset 36 [-Warray-bounds]

memcpy(). Now that a new struct wl3501_req enclosing all those adjacent

&sig.beacon_period and &this->bss_set[i].beacon_period, because the

instead.
This helps with the ongoing efforts to globally enable -Warray-bounds

on memcpy().

[ Upstream commit 994d6608efe4a4c8834bdc5014c86f4bc6aceea6 ]
In early AMD desktop/mobile platforms (during 2013), when the IOMMU
Performance Counter (PMC) support was first introduced in
commit 30861ddc9cca ("perf/x86/amd: Add IOMMU Performance Counter
resource management"), there was a HW bug where the counters could not
be accessed. The result was reading of the counter always return zero.
At the time, the suggested workaround was to add a test logic prior
to initializing the PMC feature to check if the counters can be programmed
and read back the same value. This has been working fine until the more
recent desktop/mobile platforms start enabling power gating for the PMC,
which prevents access to the counters. This results in the PMC support
being disabled unnecesarily.
Unfortunatly, there is no documentation of since which generation
of hardware the original PMC HW bug was fixed. Although, it was fixed
soon after the first introduction of the PMC. Base on this, we assume
that the buggy platforms are less likely to be in used, and it should
be relatively safe to remove this legacy logic.

This reverts commit 6778ff5b21bd8e78c8bd547fd66437cf2657fd9b.
The original commit tries to address an issue, where PMC power-gating
causing the IOMMU PMC pre-init test to fail on certain desktop/mobile
platforms where the power-gating is normally enabled.
There have been several reports that the workaround still does not
guarantee to work, and can add up to 100 ms (on the worst case)
to the boot process on certain platforms such as the MSI B350M MORTAR
with AMD Ryzen 3 2200G.
Therefore, revert this commit as a prelude to removing the pre-init
test.

[ Upstream commit 48a5494d6a4cb5812f0640d9515f1876ffc7a013 ]
If we (for example) have a trans_cfg entry in the PCI IDs table,
but then don't find a full cfg entry for it in the info table,
we fall through to the code that treats the PCI ID table entry
as a full cfg entry. This obviously causes crashes later, e.g.
when trying to build the firmware name string.
Avoid such crashes by using the low bit of the pointer as a tag
for trans_cfg entries (automatically using a macro that checks
the type when assigning) and then checking that before trying to
use the data as a full entry - if it's just a partial entry at
that point, fail.
Since we're adding some macro magic, also check that the type is
in fact either struct iwl_cfg_trans_params or struct iwl_cfg,
failing compilation ("initializer element is not constant") if
it isn't.

When operating two VAP on a MT7610 with encryption (PSK2, SAE, OWE),
only the first one to be created will transmit properly encrypteded
frames.
All subsequently created VAPs will sent out frames with the payload left
unencrypted, breaking multicast traffic (ICMP6 NDP) and potentially
disclosing information to a third party.
Disable GTK offloading and encrypt these frames in software to
circumvent this issue. THis only seems to be necessary on MT7610 chips,
as MT7612 is not affected from our testing.
