[ Upstream commit e70515039d ]
During scan and remain-on-channel requests, a scan link vif (arvif) is
assigned and a temporary vdev is created. If vdev creation fails, the
assigned arvif is left attached until the virtual interface is removed,
leaving a stale link in ahvif.
Fix this by freeing the stale arvif and resetting the corresponding link in
ahvif by calling ath12k_mac_unassign_link_vif() when vdev creation fails.
While at it, propagate the actual error code from ath12k_mac_vdev_create()
instead of returning -EINVAL in ath12k_mac_initiate_hw_scan().

[ Upstream commit 448bf7b514 ]
Currently, vdev limit check is performed only in
ath12k_mac_assign_vif_to_vdev(). If the host has already created
maximum number of vdevs for the radio (ar) and a scan request
arrives for the same radio, ath12k_mac_initiate_hw_scan() attempts
to create a vdev without checking the limit, causing firmware asserts.
Centralize the vdev limit guard by moving the check into
ath12k_mac_vdev_create() so that all callers obey the limit.
While doing this, update the condition from
`num_created_vdevs > (TARGET_NUM_VDEVS(ab) - 1)` to
`num_created_vdevs >= TARGET_NUM_VDEVS(ab)` for clarity and to
eliminate unnecessary arithmetic.

[ Upstream commit 088a099690 ]
In ath12k_core_init() when ath12k_core_hw_group_create() fails,
ath12k_core_hw_group_destroy() is called where for each device below
path would get executed
ath12k_core_soc_destroy()

The detailed reason is, when qmi_handle_init() fails for a device
ab->qmi.handle is not correctly initialized. Then
ath12k_core_hw_group_create() returns failure, since error handing
is done for all device, eventually qmi_handle_release() is called for the
issue device and finally kernel crashes due to the uninitialized
ab->qmi.handle.
Fix this by moving error handling to ath12k_core_hw_group_create(), this
way the issue device can be skipped.

During firmware recovery or suspend/resume, m3 memory could be reused if
the size of the new m3 binary is equal to or less than that of the
existing memory. There will be issues for the latter case, since
m3_mem->size will be updated with a smaller value and this value is
eventually used in the free path, where the original total size should be
used instead.

memory size and use it in free path.

When triggering a stack dump via sysrq (echo t > /proc/sysrq-trigger),

The issue occurs as follows:

1. echo t > /proc/sysrq-trigger
show_trace_log_lvl
regs = unwind_get_entry_regs()
show_regs_if_on_stack(regs)
2. The stack value pointed by
`regs` keeps changing, and
so are the tags in its
KASAN shadow region.
__show_regs(regs)
regs->ax, regs->bx, ...
3. hit KASAN redzones, OOB
When task A walks task B's stack without suspending it, the continuous changes
in task B's stack (and corresponding KASAN shadow tags) may cause task A to
hit KASAN redzones when accessing obsolete values on the stack, resulting in
false positive reports.
Simply stopping the task before unwinding is not a viable fix, as it would
alter the state intended to inspect. This is especially true for diagnosing
misbehaving tasks (e.g., in a hard lockup), where stopping might fail or hide
the root cause by changing the call stack.
Therefore, fix this by disabling KASAN checks during asynchronous stack
unwinding, which is identified when the unwinding task does not match the
current task (task != current).

[ Upstream commit 622e8838a2 ]
SCTP_DBG_OBJCNT_INC() is called only when sctp_init_sock()
returns 0 after successfully allocating sctp_sk(sk)->ep.
OTOH, SCTP_DBG_OBJCNT_DEC() is called in sctp_close().
The code seems to expect that the socket is always exposed
to userspace once SCTP_DBG_OBJCNT_INC() is incremented, but
there is a path where the assumption is not true.
In sctp_accept(), sctp_sock_migrate() could fail after
sctp_init_sock().
Then, sk_common_release() does not call inet_release() nor
sctp_close(). Instead, it calls sk->sk_prot->destroy().
Let's move SCTP_DBG_OBJCNT_DEC() from sctp_close() to
sctp_destroy_sock().

[ Upstream commit ea5df88aec ]
The PTP initialization is two-step. First part are the function
vsc8584_ptp_probe_once() and vsc8584_ptp_probe() at probe time which
initialize the locks, queues, creates the PTP device. The second part is
the function vsc8584_ptp_init() at config_init() time which initialize
PTP in the HW.
For VSC8574 and VSC8572, the PTP initialization is incomplete. It is
missing the first part but it makes the second part. Meaning that the
ptp_clock_register() is never called.
There is no crash without the first part when enabling PTP but this is
unexpected because some PHys have PTP functionality exposed by the
driver and some don't even though they share the same PTP clock PTP.

To be sure an extensive test has been performed to be sure it's
safe, as downstream uses this flag for UFS as well.
As an experiment, I checked how the dma-coherent could impact
the UFS bandwidth, and it happens the max bandwidth on cached
write is slighly highter (up to 10%) while using less cpu time
since cache sync/flush is skipped.
