Currently, whether the alloc/free stack traces collection is enabled by
default for hardware tag-based KASAN depends on CONFIG_DEBUG_KERNEL.
The intention for this dependency was to only enable collection on slow
debug kernels due to a significant perf and memory impact.
As it turns out, CONFIG_DEBUG_KERNEL is not considered a debug option
and is enabled on many productions kernels including Android and Ubuntu.
As the result, this dependency is pointless and only complicates the
code and documentation.
Having stack traces collection disabled by default would make the
hardware mode work differently to to the software ones, which is
confusing.
This change removes the dependency and enables stack traces collection
by default.
Looking into the future, this default might makes sense for production
kernels, assuming we implement a fast stack trace collection approach.

Pull syscall entry fixes from Borislav Petkov:
- For syscall user dispatch, separate prctl operation from syscall
redirection range specification before the API has been made official
in 5.11.
- Ensure tasks using the generic syscall code do trap after returning
from a syscall when single-stepping is requested.

Michael Kerrisk suggested that, from an API perspective, it is a bad
idea to share the PR_SYS_DISPATCH_ defines between the prctl operation
and the selector variable.
Therefore, define two new constants to be used by SUD's selector variable
and update the corresponding documentation and test cases.
While this changes the API syscall user dispatch has never been part of a
Linux release, it will show up for the first time in 5.11.

Python retired in 2020, and some distributions do not provide the
'python' command any more.
As in commit 51839e29cb59 ("scripts: switch explicitly to Python 3"),
we need to use more specific 'python3' to invoke scripts even if they
are written in a way compatible with both Python 2 and 3.
This commit removes the variable 'PYTHON', and switches the existing
users to 'PYTHON3'.
BTW, PEP 394 (https://www.python.org/dev/peps/pep-0394/) is a helpful
material.

The most common question around building the Linux kernel with clang is
"does it work?" and the answer has always been "it depends on your
architecture, configuration, and LLVM version" with no hard answers for
users wanting to experiment. LLVM support has significantly improved
over the past couple of years, resulting in more architectures and
configurations supported, and continuous integration has made it easier
to see what works and what does not.
Add a section that goes over what architectures are supported in the
current kernel version, how they should be built (with just clang or the
LLVM utilities as well), and the level of support they receive. This
will make it easier for people to try out building their kernel with
LLVM and reporting issues that come about from it.

This document was written a long time ago. Update it.
[1] Drop the version information
The range of the supported GCC versions are always changing. The
current minimal GCC version is 4.9, and commit 1e860048c53e
("gcc-plugins: simplify GCC plugin-dev capability test") removed the
old code accordingly.
We do not need to mention specific version ranges like "all gcc versions
from 4.5 to 6.0" since we forget to update the documentation when we
raise the minimal compiler version.
[2] Drop the C compiler statements
Since commit 77342a02ff6e ("gcc-plugins: drop support for GCC <= 4.7")
the GCC plugin infrastructure only supports g++.
[3] Drop supported architectures
As of v5.11-rc4, the infrastructure supports more architectures;
arm, arm64, mips, powerpc, riscv, s390, um, and x86. (just grep
"select HAVE_GCC_PLUGINS") Again, we miss to update this document when a
new architecture is supported. Let's just say "only some architectures".
[4] Update the apt-get example
We are now discussing to bump the minimal version to GCC 5. The GCC 4.9
support will be removed sooner or later. Change the package example to
gcc-10-plugin-dev while we are here.
[5] Update the build target
Since commit ce2fd53a10c7 ("kbuild: descend into scripts/gcc-plugins/
via scripts/Makefile"), "make gcc-plugins" is not supported.
"make scripts" builds all the enabled plugins, including some other
tools.
[6] Update the steps for adding a new plugin
At first, all CONFIG options for GCC plugins were located in arch/Kconfig.
After commit 45332b1bdfdc ("gcc-plugins: split out Kconfig entries to
scripts/gcc-plugins/Kconfig"), scripts/gcc-plugins/Kconfig became the
central place to collect plugin CONFIG options. In my understanding,
this requirement no longer exists because commit 9f671e58159a ("security:
Create "kernel hardening" config area") moved some of plugin CONFIG
options to another file. Find an appropriate place to add the new CONFIG.
The sub-directory support was never used by anyone, and removed by
commit c17d6179ad5a ("gcc-plugins: remove unused GCC_PLUGIN_SUBDIR").
Remove the useless $(src)/ prefix.

The current description of ADC keys is not precise enough.
"when this key is pressed" leaves it open if a key is considered pressed
below or above the threshold. This has led to confusion:
drivers/input/keyboard/adc-keys.c ignores the meaning of thresholds and
sets the key that is closest to press-threshold-microvolt.
This patch nails down the definitions and provides an interpretation of the
supplied example.

Overlayfs's volatile option allows the user to bypass all forced sync calls
to the upperdir filesystem. This comes at the cost of safety. We can never
ensure that the user's data is intact, but we can make a best effort to
expose whether or not the data is likely to be in a bad state.
The best way to handle this in the time being is that if an overlayfs's
upperdir experiences an error after a volatile mount occurs, that error
will be returned on fsync, fdatasync, sync, and syncfs. This is
contradictory to the traditional behaviour of VFS which fails the call
once, and only raises an error if a subsequent fsync error has occurred,
and been raised by the filesystem.
One awkward aspect of the patch is that we have to manually set the
superblock's errseq_t after the sync_fs callback as opposed to just
returning an error from syncfs. This is because the call chain looks
something like this:
sys_syncfs ->
sync_filesystem ->
__sync_filesystem ->
/* The return value is ignored here
sb->s_op->sync_fs(sb)
_sync_blockdev
/* Where the VFS fetches the error to raise to userspace */
errseq_check_and_advance
Because of this we call errseq_set every time the sync_fs callback occurs.
Due to the nature of this seen / unseen dichotomy, if the upperdir is an
inconsistent state at the initial mount time, overlayfs will refuse to
mount, as overlayfs cannot get a snapshot of the upperdir's errseq that
will increment on error until the user calls syncfs.

The IP block evolved from its rk3288/rk3399 base and the vendor
designates them with a numerical version. rk3399 for example
is designated V10 probably meaning V1.0.
There doesn't seem to be an actual version register we could read that
information from, so allow the match_data to carry that information
for future differentiation.
Also carry that information in the hw_revision field of the media-
controller API, so that userspace also has access to that.
The added versions are:
- V10: at least rk3288 + rk3399
- V11: seemingly unused as of now, but probably appeared in some soc
- V12: at least rk3326 + px30
- V13: at least rk1808

"A single fix for objtool to generate proper unwind info for newer
toolchains which do not generate section symbols anymore. And a

This was originally going to go during the next merge window but

Arnd found a randconfig that produces the warning:
arch/x86/entry/thunk_64.o: warning: objtool: missing symbol for insn at
offset 0x3e
when building with LLVM_IAS=1 (Clang's integrated assembler). Josh
notes:
With the LLVM assembler not generating section symbols, objtool has no
way to reference this code when it generates ORC unwinder entries,
because this code is outside of any ELF function.
The limitation now being imposed by objtool is that all code must be
contained in an ELF symbol. And .L symbols don't create such symbols.
So basically, you can use an .L symbol *inside* a function or a code
segment, you just can't use the .L symbol to contain the code using a
SYM_*_START/END annotation pair.
Fangrui notes that this optimization is helpful for reducing image size
when compiling with -ffunction-sections and -fdata-sections. I have
observed on the order of tens of thousands of symbols for the kernel
images built with those flags.
A patch has been authored against GNU binutils to match this behavior
of not generating unused section symbols ([1]), so this will
also become a problem for users of GNU binutils once they upgrade to 2.36.
Omit the .L prefix on a label so that the assembler will emit an entry
into the symbol table for the label, with STB_LOCAL binding. This
enables objtool to generate proper unwind info here with LLVM_IAS=1 or
GNU binutils 2.36+.

Properties with standard unit suffixes already have a type and don't need
type definitions. They also default to a single entry, so 'maxItems: 1'
can be dropped.
adi,ad5758 is an oddball which defined an enum of arrays. While a valid
schema, it is simpler as a whole to only define scalar constraints.

The use of a tagged address could be pretty confusing for the
whole memslot infrastructure as well as the MMU notifiers.
Forbid it altogether, as it never quite worked the first place.

The initially proposed KASAN command line parameters are redundant.
This change drops the complex "kasan.mode=off/prod/full" parameter and
adds a simpler kill switch "kasan=off/on" instead. The new parameter
together with the already existing ones provides a cleaner way to
express the same set of features.
The full set of parameters with this change:
kasan=off/on - whether KASAN is enabled
kasan.fault=report/panic - whether to only print a report or also panic
kasan.stacktrace=off/on - whether to collect alloc/free stack traces
Default values:
kasan=on
kasan.fault=report
kasan.stacktrace=on (if CONFIG_DEBUG_KERNEL=y)
kasan.stacktrace=off (otherwise)

Pull driver core fixes from Greg KH:
"Here are some small driver core fixes for 5.11-rc5 that resolve some
reported problems:
- revert of a -rc1 patch that was causing problems with some machines
- device link device name collision problem fix (busses only have to
name devices unique to their bus, not unique to all busses)
- kernfs splice bugfixes to resolve firmware loading problems for
Qualcomm systems.
- other tiny driver core fixes for minor issues reported.
All of these have been in linux-next with no reported problems"

The device link device's name was of the form:
<supplier-dev-name>--<consumer-dev-name>
This can cause name collision as reported here [1] as device names are
not globally unique. Since device names have to be unique within the
bus/class, add the bus/class name as a prefix to the device names used to
construct the device link device name.

<supplier-bus-name>:<supplier-dev-name>--<consumer-bus-name>:<consumer-dev-name>
