commit 442f1e746e8187b9deb1590176f6b0ff19686b11 upstream.
Commit 4b708b7b1a2c ("firmware: google: check if size is valid when
decoding VPD data") adds length checks, but the new vpd_decode_entry()
function botched the logic -- it adds the key length twice, instead of
adding the key and value lengths separately.
On my local system, this means vpd.c's vpd_section_create_attribs() hits
an error case after the first attribute it parses, since it's no longer
looking at the correct offset. With this patch, I'm back to seeing all
the correct attributes in /sys/firmware/vpd/...

commit c05f8f92b701576b615f30aac31fabdc0648649b upstream.
The kernel command line option efivar_ssdt= allows the name to be
specified of an EFI variable containing an ACPI SSDT table that should
be loaded into memory by the OS, and treated as if it was provided by
the firmware.
Currently, that code will always iterate over the EFI variables and
compare each name with the provided name, even if the command line
option wasn't set to begin with.
So bail early when no variable name was provided. This works around a
boot regression on the 2012 Mac Pro, as reported by Scott.

[ Upstream commit 9dc34d635c67e57051853855c43249408641a5ab ]
Sometimes platfom may take too long to respond to the command and OS
might timeout before platform transfer the ownership of the shared
memory region to the OS with the response.
Since the mailbox channel associated with the channel is freed and new
commands are dispatch on the same channel, OS needs to wait until it
gets back the ownership. If not, either OS may end up overwriting the
platform response for the last command(which is fine as OS timed out
that command) or platform might overwrite the payload for the next
command with the response for the old.
The latter is problematic as platform may end up interpretting the
response as the payload. In order to avoid such race, let's wait until
the OS gets back the ownership before we prepare the shared memory with
the payload for the next command.

[ Upstream commit b194a77fcc4001dc40aecdd15d249648e8a436d1 ]
AER info of PCIe fatal error is not printed in the current driver.
Because APEI driver will panic directly for fatal error, and can't
run to the place of printing AER info.
An example log is as following:
{763}[Hardware Error]: Hardware error from APEI Generic Hardware Error Source: 11
{763}[Hardware Error]: event severity: fatal
{763}[Hardware Error]: Error 0, type: fatal
{763}[Hardware Error]: section_type: PCIe error

{763}[Hardware Error]: vendor_id: 0x8086, device_id: 0x10fb
{763}[Hardware Error]: class_code: 000002
Kernel panic - not syncing: Fatal hardware error!
This issue was imported by the patch, '37448adfc7ce ("aerdrv: Move
cper_print_aer() call out of interrupt context")'. To fix this issue,
this patch adds print of AER info in cper_print_pcie() for fatal error.
Here is the example log after this patch applied:
{24}[Hardware Error]: Hardware error from APEI Generic Hardware Error Source: 10
{24}[Hardware Error]: event severity: fatal

[ Upstream commit 6e37ccf78a53296c6c7bf426065762c27829eb84 ]
We need to use the proper types and convert between physical addresses
and dma addresses here to avoid mismatch warnings. This is especially
important on systems with a different size for dma addresses and
physical addresses. Otherwise, we get the following warning:
drivers/firmware/qcom_scm.c: In function "qcom_scm_assign_mem":
drivers/firmware/qcom_scm.c:469:47: error: passing argument 3 of "dma_alloc_coherent" from incompatible pointer type [-Werror=incompatible-pointer-types]
We also fix the size argument to dma_free_coherent() because that size
doesn't need to be aligned after it's already aligned on the allocation
size. In fact, dma debugging expects the same arguments to be passed to
both the allocation and freeing sides of the functions so changing the
size is incorrect regardless.

commit 4b708b7b1a2c09fbdfff6b942ebe3a160213aacd upstream.
The VPD implementation from Chromium Vital Product Data project used to
parse data from untrusted input without checking if the meta data is
invalid or corrupted. For example, the size from decoded content may
be negative value, or larger than whole input buffer. Such invalid data
may cause buffer overflow.
To fix that, the size parameters passed to vpd_decode functions should
be changed to unsigned integer (u32) type, and the parsing of entry
header should be refactored so every size field is correctly verified
before starting to decode.

commit 66f030eac257a572fbedab3d9646d87d647351fd upstream.
TI-SCI firmware will only respond to messages when the
TI_SCI_FLAG_REQ_ACK_ON_PROCESSED flag is set. Most messages already do
this, set this for the ones that do not.
This will be enforced in future firmware that better match the TI-SCI
specifications, this patch will not break users of existing firmware.

[ Upstream commit 94bccc34071094c165c79b515d21b63c78f7e968 ]
iscsi_ibft can use ACPI to find the iBFT entry during bootup,
currently, ISCSI_IBFT depends on ISCSI_IBFT_FIND which is
a X86 legacy way to find the iBFT by searching through the
low memory. This patch changes the dependency so that other
arch like ARM64 can use ISCSI_IBFT as long as the arch supports
ACPI.
ibft_init() needs to use the global variable ibft_addr declared
in iscsi_ibft_find.c. A #ifndef CONFIG_ISCSI_IBFT_FIND is needed
to declare the variable if CONFIG_ISCSI_IBFT_FIND is not selected.
Moving ibft_addr into the iscsi_ibft.c does not work because if
ISCSI_IBFT is selected as a module, the arch/x86/kernel/setup.c won't
be able to find the variable at compile time.

Since commit 85f1abe0019f ("kthread, sched/wait: Fix kthread_parkme()

before being stopped. At the moment the PSCI checker calls
kthread_stop() directly on the suspend kthread, which triggers the
following warning:

Pull EFI fixes from Ingo Molnar:
"Four fixes:
- fix a kexec crash on arm64
- fix a reboot crash on some Android platforms
- future-proof the code for upcoming ACPI 6.2 changes
- fix a build warning on x86"
* 'efi-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
efibc: Replace variable set function in notifier call
x86/efi: fix a -Wtype-limits compilation warning
efi/bgrt: Drop BGRT status field reserved bits check
efi/memreserve: deal with memreserve entries in unmapped memory
|

Replace the variable set function from "efivar_entry_set" to
"efivar_entry_set_safe" in efibc panic notifier.
In safe function parameter "block" will set to false
and will call "efivar_entry_set_nonblocking"to set efi variables.
efivar_entry_set_nonblocking is guaranteed to
not block and is suitable for calling from crash/panic handlers.
In UEFI android platform, when warm reset happens,
with this change, efibc will not block the reboot process.
Otherwise, set variable will call queue work and send to other offlined
cpus then cause another panic, finally will cause reboot failure.

Pull still more SPDX updates from Greg KH:
"Another round of SPDX updates for 5.2-rc6
Here is what I am guessing is going to be the last "big" SPDX update
for 5.2. It contains all of the remaining GPLv2 and GPLv2+ updates
that were "easy" to determine by pattern matching. The ones after this
are going to be a bit more difficult and the people on the spdx list
will be discussing them on a case-by-case basis now.
Another 5000+ files are fixed up, so our overall totals are:
Files checked: 64545
Files with SPDX: 45529
Compared to the 5.1 kernel which was:
Files checked: 63848
Files with SPDX: 22576
This is a huge improvement.
Also, we deleted another 20000 lines of boilerplate license crud,
always nice to see in a diffstat"

i.MX fixes for 5.2:
- A build fix for soc-imx8 driver which needs SOC_BUS support. To
avoid dealing with the dependency for every single i.MX SoC bus
driver, we selects at from architecture level.
- A fix on i.MX SCU firmware driver to ensure SCU irq is enabled only
after IPC is ready.
- A regression fix on cpuidle-imx6sx driver, which causes some
characters loss on serial communication.

ARM: imx: cpuidle-imx6sx: Restrict the SW2ISO increase to i.MX6SX
