ACPICA: acpi_madt_oem_data: Fix flexible array member definition

2023-04-06T18:29:12+00:00

ACPICA commit e7f6d8c1b7f79eb4b9b07f1bc09c549a2acbd6e8

Use ACPI_FLEX_ARRAY() helper to define flexible array member alone in a
struct. Fixes issue #812.

No binary changes appear in the .text nor .data sections.

ACPICA: struct acpi_nfit_interleave: Replace 1-element array with flexible array

2023-04-06T18:29:12+00:00

ACPICA commit e66decc6fca36b59194b0947d87d6a9bec078bc3

Similar to "Replace one-element array with flexible-array", replace the
1-element array with a proper flexible array member as defined by C99.

This allows the code to operate without tripping compile-time and run-
time bounds checkers (e.g. via __builtin_object_size(), -fsanitize=bounds,
and/or -fstrict-flex-arrays=3).

Unlike struct acpi_nfit_flush_address and struct acpi_nfit_smbios, which
had their sizeof() uses adjusted in code, struct acpi_nfit_interleave did
not. This appears to have been a bug. After this change, there is a binary
difference in acpi_dm_dump_nfit() since the size of the structure now has
the correct size, as the prior result was including the trailing U32:

-       mov    $0x14,%ebp
+       mov    $0x10,%ebp

ACPICA: actbl2: Replace 1-element arrays with flexible arrays

2023-04-06T18:29:11+00:00

ACPICA commit 44f1af0664599e87bebc3a1260692baa27b2f264

Similar to "Replace one-element array with flexible-array", replace the
1-element array with a proper flexible array member as defined by C99.

This allows the code to operate without tripping compile-time and run-
time bounds checkers (e.g. via __builtin_object_size(), -fsanitize=bounds,
and/or -fstrict-flex-arrays=3).

The sizeof() uses with struct acpi_nfit_flush_address and struct
acpi_nfit_smbios have been adjusted to drop the open-coded subtraction
of the trailing single element. The result is no binary differences in
.text nor .data sections.

ACPICA commit 005e24bcaa6e4c7db327b4f81fb63b2715aac7e6

Complies with ACPI for Memory System Resource Partitioning and
Monitoring 2.0 [1]. Document number: DEN0065, as of December 2022.

Support for all types of MPAM resources. No support yet for:
1) MPAM PCC Interface Type
2) The optional Resource-specific data per MSC node, introduced in v2 of the
MPAM ACPI spec.

ACPICA: Headers: Delete bogus node_array array of pointers from AEST table

2023-04-06T18:29:10+00:00

ACPICA commit f0c4a06f1dfc4886d4e0c2aa30bc57b10c5a8c53

Like many tables, this is a header followed by multiple subtables of
varying self-identifying types, and ACPICA does not normally add a field
for the subtables, instead relying on pointer arithmetic past the end of
the first header struct, since indexing a flexible array member is
meaningless for variable-length entries. If we really wanted a field for
this, we could use a u8 flexible array member, but it contradicts the
current style. Using void *, however, is categorically wrong, as ACPI
tables never contain native C-language pointers.
