[ Upstream commit 4c8874c2a6512b9fe7285cab1a6910d9211a6cfb ]
The SOC_HW_VERSION register in the BHI space is not correctly initialized
by the device and in many cases contains uninitialized data. The register
could contain 0xFFFFFFFF which is a special value to indicate a link
error in PCIe, therefore if observed, we could incorrectly think the
device is down.
Intercept reads for this register, and provide the correct value - every
production instance would read 0x60110200 if the device was operating as
intended.

There is no need to call MMIO reset using VPU_37XX_BUTTRESS_VPU_IP_RESET
register. IP will be reset by FLR or by entering d0i3. Also IP reset
during power_up is not needed as the VPU is already in reset.
Removing MMIO reset improves stability as it a partial device reset
that is not safe in some corner cases.

We need to wait for the CLOCK_RESOURCE_OWN_ACK bit to be set
after configuring the workpoint. This step ensures that the VPU
microcontroller clock is actively toggling and ready for operation.
Previously, we relied solely on the READY bit in the VPU_STATUS
register, which indicated the completion of the workpoint download.
However, this approach was insufficient, as the READY bit could be set
while the device was still running on a sideband clock until the PLL
locked. To guarantee that the PLL is locked and the device is running on
the main clock source, we now wait for the CLOCK_RESOURCE_OWN_ACK before
proceeding with the remainder of the power-up sequence.

`strncpy` is deprecated for use on NUL-terminated destination strings [1].
A suitable replacement is `strscpy` [2] due to the fact that it
guarantees NUL-termination on its destination buffer argument which is
_not_ the case for `strncpy`!
Also remove extraneous if-statement as it can never be entered. The
return value from `strncpy` is it's first argument. In this case,
`...dyndbg_cmd` is an array:
| char dyndbg_cmd[VPU_DYNDBG_CMD_MAX_LEN];
^^^^^^^^^^
This can never be NULL which means `strncpy`'s return value cannot be
NULL here. Just use `strscpy` which is more robust and results in
simpler and less ambiguous code.
Moreover, remove needless `... - 1` as `strscpy`'s implementation
ensures NUL-termination and we do not need to carefully dance around
ending boundaries with a "- 1" anymore.

The encode_dma() function has some validation on in_trans->size but it
would be more clear to move those checks to find_and_map_user_pages().
The encode_dma() had two checks:
if (in_trans->addr + in_trans->size < in_trans->addr || !in_trans->size)
return -EINVAL;
The in_trans->addr variable is the starting address. The in_trans->size
variable is the total size of the transfer. The transfer can occur in
parts and the resources->xferred_dma_size tracks how many bytes we have
already transferred.
This patch introduces a new variable "remaining" which represents the
amount we want to transfer (in_trans->size) minus the amount we have
already transferred (resources->xferred_dma_size).
I have modified the check for if in_trans->size is zero to instead check
if in_trans->size is less than resources->xferred_dma_size. If we have
already transferred more bytes than in_trans->size then there are negative
bytes remaining which doesn't make sense. If there are zero bytes
remaining to be copied, just return success.
The check in encode_dma() checked that "addr + size" could not overflow
and barring a driver bug that should work, but it's easier to check if
we do this in parts. First check that "in_trans->addr +
resources->xferred_dma_size" is safe. Then check that "xfer_start_addr +
remaining" is safe.
My final concern was that we are dealing with u64 values but on 32bit
systems the kmalloc() function will truncate the sizes to 32 bits. So
I calculated "total = in_trans->size + offset_in_page(xfer_start_addr);"
and returned -EINVAL if it were >= SIZE_MAX. This will not affect 64bit
systems.

memory content such as MMU translation faults, invalid context
descriptors being fetched and can lead to VPU FW crashes.

The encode_dma() function has integer overflow checks. The

did not. I added integer overflow checking everywhere. I also
updated the integer overflow checking in encode_dma() to use size_add()

Copy the bounds checking from encode_message() to decode_message().
This patch addresses the following concerns. Ensure that there is
enough space for at least one header so that we don't have a negative
size later.
if (msg_hdr_len < sizeof(*trans_hdr))
Ensure that we have enough space to read the next header from the
msg->data.
if (msg_len > msg_hdr_len - sizeof(*trans_hdr))
return -EINVAL;
Check that the trans_hdr->len is not below the minimum size:
if (hdr_len < sizeof(*trans_hdr))
This minimum check ensures that we don't corrupt memory in
decode_passthrough() when we do.
memcpy(out_trans->data, in_trans->data, len - sizeof(in_trans->hdr));
And finally, use size_add() to prevent an integer overflow:
if (size_add(msg_len, hdr_len) > msg_hdr_len)

There are several issues in this code. The check at the start of the
loop:
if (user_len >= user_msg->len) {
This check does not ensure that we have enough space for the trans_hdr
(8 bytes). Instead the check needs to be:
if (user_len > user_msg->len - sizeof(*trans_hdr)) {
That subtraction is done as an unsigned long we want to avoid
negatives. Add a lower bound to the start of the function.
if (user_msg->len < sizeof(*trans_hdr))
There is a second integer underflow which can happen if
trans_hdr->len is zero inside the encode_passthrough() function.
memcpy(out_trans->data, in_trans->data, in_trans->hdr.len - sizeof(in_trans->hdr));
Instead of adding a check to encode_passthrough() it's better to check
in this central place. Add that check:
if (trans_hdr->len < sizeof(trans_hdr)
The final concern is that the "user_len + trans_hdr->len" might have an
integer overflow bug. Use size_add() to prevent that.
- if (user_len + trans_hdr->len > user_msg->len) {
+ if (size_add(user_len, trans_hdr->len) > user_msg->len) {
