The 20170303 ACPICA kernel-resident subsystem updates are linuxized based
on the linux-pm/linux-next branch.
The patchset has passed the following build/boot tests.
Build tests are performed as follows:
1. i386 + allyes
2. i386 + allno
3. i386 + default + ACPI_DEBUGGER=y
4. i386 + default + ACPI_DEBUGGER=n + ACPI_DEBUG=y
5. i386 + default + ACPI_DEBUG=n + ACPI=y
6. i386 + default + ACPI=n
7. x86_64 + allyes
8. x86_64 + allno
9. x86_64 + default + ACPI_DEBUGGER=y
10.x86_64 + default + ACPI_DEBUGGER=n + ACPI_DEBUG=y
11.x86_64 + default + ACPI_DEBUG=n + ACPI=y
12.x86_64 + default + ACPI=n
Boot tests are performed as follows:
1. x86_64 + default + ACPI_DEBUGGER=y
Where:
1. i386: machine named as "Dell Inspiron Mini 1010"
2. x86_64: machine named as "Microsoft Surface Pro 3"
3. default: kernel configuration with following items enabled:
All hardware drivers related to the machines of i386/x86_64
All "drivers/acpi" configurations
All "drivers/platform" drivers
All other drivers that link the APIs provided by ACPICA subsystem
The divergences checking result:

ACPICA commit ba5020b2dbe1538e4ccd7ac2dfd8843a690c007f
This change enhances the detection of resource descriptors
within a buffer object. For the end_tag opcode, the second byte
is defined to be either a checksum or zero. All known ASL compilers
insert a zero for this byte. The disassembler now ensures this
byte is zero before deciding that a buffer should be disassembled
to a resource descriptor. This helps eliminate incorrect decisions
when attempting to disassemble a buffer to a resource descriptor.

ACPICA commit a23325b2e583556eae88ed3f764e457786bf4df6

When early abort is occurred due to invalid ACPI information, Linux kernel
terminates ACPI by calling acpi_terminate() function. The function calls
acpi_ns_terminate() function to delete namespace data and ACPI operand cache
(acpi_gbl_module_code_list).
But the deletion code in acpi_ns_terminate() function is wrapped in
ACPI_EXEC_APP definition, therefore the code is only executed when the
definition exists. If the define doesn't exist, ACPI operand cache
(acpi_gbl_module_code_list) is leaked, and stack dump is shown in kernel log.
This causes a security threat because the old kernel (<= 4.9) shows memory
locations of kernel functions in stack dump, therefore kernel ASLR can be
neutralized.
To fix ACPI operand leak for enhancing security, I made a patch which
removes the ACPI_EXEC_APP define in acpi_ns_terminate() function for
executing the deletion code unconditionally.

ACPICA commit 6b58810b9aad7358fbf1a0f4057fefa8d29838d3
This change fixes two instances where the repair code made an incorrect
assumption about how reference counts are assigned to package objects.
Resolves issues where a warning was issued about a "large reference
count" -- which usually indicates an attempt to delete an object
that has previously been poisoned and released into the object cache.

On the error return path when acpi_get_object_info fails the allocated
pathname is not free'd leading to a memory leak. Free pathname
to fix this.

ACPICA commit 91af5d18cd40b35f9d5568fb95fc403ff12474e5
When the single-step mode is used, evaluation is actually split by the
single-step command prompts, so this patch correctly marks the evaluation
segment with interpreter lock release/acquire.
This in return fixes an issue that in the single-step command prompt,
commands requiring to hold the namespace lock (ex. namespace) cannot be
executed. ACPICA BZ 1362, fixed by Lv Zheng.

ACPICA commit 637b88de24a78c20478728d9d66632b06fcaa5bf
If the IORT template is compiled and then iort.aml binary disassembled to
iort.dsl, SMMUv1 node lists incorrect offset for SMMU_Nsg_cfg_irpt Interrupt:
[0ECh 0236 8] SMMU_Nsg_irpt Interrupt : 0000000000000000
[0ECh 0236 8] SMMU_Nsg_cfg_irpt Interrupt : 0000000000000000
This is because iasl hasn't implemented SMMU GSI decoding yet.
This patch fixes this issue by preparing structures for decoding IORT SMMU
GSI. ACPICA BZ 1340, reported by Alexei Fedorov, fixed by Lv Zheng.

ACPICA commit c46f496df41e53a368f877f88b70bdfc9bd6fdbe
Change the Switch disassembly code to check if the conversion can be
done before removing temporary (_T_x) names. Prevents invalid
disassembly of AML created by older compilers (circa 2005).

ACPICA commit c04d310039d3e0ed1cb62876fe7e596fbc75ab01
The key feature of this utility is that the original comments within
the input ASL files are preserved during the conversion process, and
included within the converted ASL+ file -- thus creating a transparent
conversion of existing ASL files to ASL+ (ASL 2.0)

ACPICA commit 9c54b8bbd483421ef2fef5225c00f1655b4a491c
Remove apparently arbitrary restriction on the size of the cache
objects to 16 (in acpi_os_create_cache). Now, the input object
size must be simply non-zero.

Hi,
It's fixed by PATCH 14 in the same series.
I'll combine them in order not to break bisection processes.
Thanks

ACPICA commit c04d310039d3e0ed1cb62876fe7e596fbc75ab01
ACPICA commit a65c1df7e6b4bad8e37df822018c40c6c446add9
The key feature of this utility is that the original comments within
the input ASL files are preserved during the conversion process, and
included within the converted ASL+ file -- thus creating a transparent
conversion of existing ASL files to ASL+ (ASL 2.0)
This patch is an automatic generation of the ASL converter commit,
Linux kernel isn't affected by the functionality provided in this
commit, but requires the linuxized changes to support future ACPICA
release automation.

This commit breaks things on my platform. I'm testing on an HPE ProLiant DL380Gen9
but I also see errors on other ProLiant servers, including much older ones.
With this commit, I see errors like:

This causes random things to break, such as the ability for an ACPI method
to make IPMI calls because ipmi_si doesn't find the ACPI-specified BMC.

If I replace the return with an ACPI_ERROR, I get output like this:
[ 4.497662] ACPI Error: Non-zero value: 0xE5 (20170303/utresrc-484)
[ 4.500111] ACPI Error: Non-zero value: 0xE5 (20170303/utresrc-484)
[ 4.506862] ACPI Error: Non-zero value: 0xE5 (20170303/utresrc-484)
[ 4.509011] ACPI Error: Non-zero value: 0xE5 (20170303/utresrc-484)
[ 4.516777] ACPI Error: Non-zero value: 0x50 (20170303/utresrc-484)
[ 4.519710] ACPI Error: Non-zero value: 0x50 (20170303/utresrc-484)
[ 4.541214] ACPI Error: Non-zero value: 0xE4 (20170303/utresrc-484)
[ 4.543670] ACPI Error: Non-zero value: 0xE4 (20170303/utresrc-484)
[ 4.584594] ACPI Error: Non-zero value: 0x07 (20170303/utresrc-484)
[ 4.586754] ACPI Error: Non-zero value: 0x11 (20170303/utresrc-484)
By not returning an error, I no longer see the other errors and everything
seems to work.
I haven't yet determined whether the non-zero value is a valid checksum but
it's definitely not zero.
If the byte is technically defined to be a checksum, then the code ought to
accept a valid checksum. If it turns out that my platform isn't actually
providing a valid checksum, then I'd like to see a warning or something
rather than a error, since this change will break a lot of systems.

I talked to our FW team and we do generate checksums and not a zero for at
least some
of the AML. Please revert this change until you can also validate
a checksum. Or shall I post a patch to remove the check?

I'll skip this patch, no need to do anything else. Thanks for your report!
Bob, can you revert this upstream, please? It looks like the
assumption it is based on doesn't hold.
Thanks,

Thanks. This patch is already in as of 4.12rc1 and not part of the most recent
ACPICA drop.

Bob, I'm happy to test something if there is a new patch that looks for zero
or a valid checksum. TBH, I'm not 100% certain that our checksums are
correct because nothing has ever tried to verify them.

Ah, OK.
I should have checked I guess. :-)
Anyway, I'll revert it, then.

Well, that's part of the problem here I guess. If they have never
been tested, they cannot be trusted.
Still, the commit in question clearly assumed that value to always be
0 and it clearly is not the case here.
Thanks,

Just stumbled across this on the moonshot m400 and breaks the parsing
of the PNP0A08 _CRS on that platform.

Hi Rafael, Is this still in the queue to be reverted?
I see it's still in rc5 but it really needs to go before 4.12 is released.
We've been broken since rc1.

[Moore, Robert]
It is on our list of things to look at, now that acpi 6.2 is released.
This has been a rather odd problem that we have been trying to fix for some time now; so we will of course need to come up with a permanent fix.
