The cited commit introduced the following coverity issue at function
mlx5_tc_ct_rule_to_tuple_nat:
- Memory - corruptions (OVERRUN)
Overrunning array "tuple->ip.src_v6.in6_u.u6_addr32" of 4 4-byte
elements at element index 7 (byte offset 31) using index
"ip6_offset" (which evaluates to 7).
In case of IPv6 destination address rewrite, ip6_offset values are
between 4 to 7, which will cause memory overrun of array
"tuple->ip.src_v6.in6_u.u6_addr32" to array
"tuple->ip.dst_v6.in6_u.u6_addr32".
Fixed by writing the value directly to array
"tuple->ip.dst_v6.in6_u.u6_addr32" in case ip6_offset values are
between 4 to 7.

Prior to this fix, in Striding RQ mode the driver was vulnerable when
receiving packets in the range (stride size - headroom, stride size].
Where stride size is calculated by mtu+headroom+tailroom aligned to the
closest power of 2.
Usually, this filtering is performed by the HW, except for a few cases:
- Between 2 VFs over the same PF with different MTUs
- On bluefield, when the host physical function sets a larger MTU than
the ARM has configured on its representor and uplink representor.
When the HW filtering is not present, packets that are larger than MTU
might be harmful for the RQ's integrity, in the following impacts:
1) Overflow from one WQE to the next, causing a memory corruption that
in most cases is unharmful: as the write happens to the headroom of next
packet, which will be overwritten by build_skb(). In very rare cases,
high stress/load, this is harmful. When the next WQE is not yet reposted
and points to existing SKB head.
2) Each oversize packet overflows to the headroom of the next WQE. On
the last WQE of the WQ, where addresses wrap-around, the address of the
remainder headroom does not belong to the next WQE, but it is out of the
memory region range. This results in a HW CQE error that moves the RQ
into an error state.
Solution:
Add a page buffer at the end of each WQE to absorb the leak. Actually
the maximal overflow size is headroom but since all memory units must be
of the same size, we use page size to comply with UMR WQEs. The increase
in memory consumption is of a single page per RQ. Initialize the mkey
with all MTTs pointing to a default page. When the channels are
activated, UMR WQEs will redirect the RX WQEs to the actual memory from
the RQ's pool, while the overflow MTTs remain mapped to the default page.

In case of pci is offline reclaim_pages_cmd() will still try to call
the FW to release FW pages, cmd_exec() in this case will return a silent
success without actually calling the FW.
This is wrong and will cause page leaks, what we should do is to detect
pci offline or command interface un-available before tying to access the
FW and manually release the FW pages in the driver.
In this patch we share the code to check for FW command interface
availability and we call it in sensitive places e.g. reclaim_pages_cmd().
Alternative fix:
1. Remove MLX5_CMD_OP_MANAGE_PAGES form mlx5_internal_err_ret_value,
command success simulation list.
2. Always Release FW pages even if cmd_exec fails in reclaim_pages_cmd().

It is possible that new command entry index allocation will temporarily
fail. The new command holds the semaphore, so it means that a free entry
should be ready soon. Add one second retry mechanism before returning an
error.
Patch "net/mlx5: Avoid possible free of command entry while timeout comp
handler" increase the possibility to bump into this temporarily failure
as it delays the entry index release for non-callback commands.

Once driver detects a command interface command timeout, it warns the
user and returns timeout error to the caller. In such case, the entry of
the command is not evacuated (because only real event interrupt is allowed
to clear command interface entry). If the HW event interrupt
of this entry will never arrive, this entry will be left unused forever.
Command interface entries are limited and eventually we can end up without
the ability to post a new command.
In addition, if driver will not consume the EQE of the lost interrupt and
rearm the EQ, no new interrupts will arrive for other commands.
Add a resiliency mechanism for manually polling the command EQ in case of
a command timeout. In case resiliency mechanism will find non-handled EQE,
it will consume it, and the command interface will be fully functional
again. Once the resiliency flow finished, wait another 5 seconds for the
command interface to complete for this command entry.
Define mlx5_cmd_eq_recover() to manage the cmd EQ polling resiliency flow.
Add an async EQ spinlock to avoid races between resiliency flows and real
interrupts that might run simultaneously.

Upon command completion timeout, driver simulates a forced command
completion. In a rare case where real interrupt for that command arrives
simultaneously, it might release the command entry while the forced
handler might still access it.
Fix that by adding an entry refcount, to track current amount of allowed
handlers. Command entry to be released only when this refcount is
decremented to zero.
Command refcount is always initialized to one. For callback commands,
command completion handler is the symmetric flow to decrement it. For
non-callback commands, it is wait_func().
Before ringing the doorbell, increment the refcount for the real completion
handler. Once the real completion handler is called, it will decrement it.
For callback commands, once the delayed work is scheduled, increment the
refcount. Upon callback command completion handler, we will try to cancel
the timeout callback. In case of success, we need to decrement the callback
refcount as it will never run.
In addition, gather the entry index free and the entry free into a one
flow for all command types release.

As part of driver unload, it destroys the commands EQ (via FW command).
As the commands EQ is destroyed, FW will not generate EQEs for any command
that driver sends afterwards. Driver should poll for later commands status.
Driver commands mode metadata is updated before the commands EQ is
actually destroyed. This can lead for double completion handle by the
driver (polling and interrupt), if a command is executed and completed by
FW after the mode was changed, but before the EQ was destroyed.
Fix that by using the mlx5_cmd_allowed_opcode mechanism to guarantee
that only DESTROY_EQ command can be executed during this time period.

cfae58ed681c ("platform/x86: intel-vbtn: Only blacklist SW_TABLET_MODE
on the 9 / "Laptop" chasis-type")
1fac39fd0316 ("platform/x86: intel-vbtn: Also handle tablet-mode switch on
"Detachable" and "Portable" chassis-types")
Enabled reporting of SW_TABLET_MODE on more devices since the vbtn ACPI
interface is used by the firmware on some of those devices to report this.
Testing has shown that unconditionally enabling SW_TABLET_MODE reporting
on all devices with a chassis type of 8 ("Portable") or 10 ("Notebook")
which support the VGBS method is a very bad idea.
Many of these devices are normal laptops (non 2-in-1) models with a VGBS
which always returns 0, which we translate to SW_TABLET_MODE=1. This in
turn causes userspace (libinput) to suppress events from the builtin
keyboard and touchpad, making the laptop essentially unusable.
Since the problem of wrongly reporting SW_TABLET_MODE=1 in combination
with libinput, leads to a non-usable system. Where as OTOH many people will
not even notice when SW_TABLET_MODE is not being reported, this commit
changes intel_vbtn_has_switches() to use a DMI based allow-list.
The new DMI based allow-list matches on the 31 ("Convertible") and
32 ("Detachable") chassis-types, as these clearly are 2-in-1s and
so far if they support the intel-vbtn ACPI interface they all have
properly working SW_TABLET_MODE reporting.
Besides these 2 generic matches, it also contains model specific matches
for 2-in-1 models which use a different chassis-type and which are known
to have properly working SW_TABLET_MODE reporting.
This has been tested on the following 2-in-1 devices:
Dell Venue 11 Pro 7130 vPro
HP Pavilion X2 10-p002nd
HP Stream x360 Convertible PC 11
Medion E1239T

Nathan reports that building the new mokvar table code for 32-bit
ARM fails with errors such as
error: implicit declaration of function 'early_memunmap'
error: implicit declaration of function 'early_memremap'
This is caused by the lack of an explicit #include of the appropriate
header, and ARM apparently does not inherit that inclusion via another
header file. So add the #include.

As before, when the ZIP device is too busy to creat a request, it will
return '-EBUSY'. But the crypto process think the '-EBUSY' means a
successful request and wait for its completion.
So replace '-EBUSY' with '-EAGAIN' to show crypto this request is failed.

from Chuanhong Guo <gch981213@gmail.com>:
"program" mode on this controller can trigger up to 56 bits of data
shifting. During the operation, data in PRGDATA[0-5] will be
shifted out from MOSI, and data from MISO will be continuously filling
SHREG[0-9].
Currently this mode is used to implement transfer_one_message for 6-byte
full-duplex transfer, but it can execute a transfer for up-to 7 bytes
as long as the last byte is read only.
transfer_one_message is expected to perform full-duplex transfer,
instead of transfer with specific format. mtk_nor_spi_mem_prg is
added here to use this extra byte.
Newer version of this controller can trigger longer data shifting with
shift bytes more than PRGDATA_MAX + SHREG_MAX. This patch is implemented
with that in mind and it checks against both SHREG_MAX and PRG_CNT_MAX
for future support of new controllers.
Patch 3/3 is a fix for:
commit a59b2c7c56bf7 ("spi: spi-mtk-nor: support standard spi properties")
which breaks supports_op logic. But it can't be separated as it depends
on patch 2/3. Fortuantely the broken commit isn't in stable yet.
Chuanhong Guo (3):
spi: spi-mtk-nor: make use of full capability of prg mode
spi: spi-mtk-nor: add helper for checking prg mode ops
spi: spi-mtk-nor: fix op checks in supports_op

commit a59b2c7c56bf7 ("spi: spi-mtk-nor: support standard spi properties")
tries to inverse the logic of supports_op when adding
spi_mem_default_supports_op check, but it didn't get it done properly.
There are two regressions introduced by this commit:
1. reading ops supported by program mode is rejected.
2. all ops with special controller routines are incorrectly further
checked against program mode.
This commits inverses the logic back:
1. check spi_mem_default_supports_op and reject unsupported ops first.
2. return true for ops with special controller routines.
3. check the left ops against controller program mode.
