FROMGIT: kasan: Add KASAN mode kernel parameter
Architectures supported by KASAN_HW_TAGS can provide a sync or async mode
of execution. On an MTE enabled arm64 hw for example this can be identified
with the synchronous or asynchronous tagging mode of execution.
In synchronous mode, an exception is triggered if a tag check fault occurs.
In asynchronous mode, if a tag check fault occurs, the TFSR_EL1 register is
updated asynchronously. The kernel checks the corresponding bits
periodically.
KASAN requires a specific kernel command line parameter to make use of this
hw features.
Add KASAN HW execution mode kernel command line parameter.
Note: This patch adds the kasan.mode kernel parameter and the
sync/async kernel command line options to enable the described features.
[ Add a new var instead of exposing kasan_arg_mode to be consistent with
flags for other command line arguments. ]

FROMGIT: kasan: init memory in kasan_(un)poison for HW_TAGS
This change adds an argument to kasan_poison() and kasan_unpoison() that allows initializing memory along with setting the tags for HW_TAGS. Combining setting allocation tags with memory initialization will improve HW_TAGS KASAN performance when init_on_alloc/free is enabled. This change doesn't integrate memory initialization with KASAN, this is done is subsequent patches in this series.

BACKPORT: kasan: remove redundant config option
CONFIG_KASAN_STACK and CONFIG_KASAN_STACK_ENABLE both enable KASAN stack instrumentation, but we should only need one config, so that we remove CONFIG_KASAN_STACK_ENABLE and make CONFIG_KASAN_STACK workable. see [1].

FROMGIT: kasan: fix KASAN_STACK dependency for HW_TAGS
There's a runtime failure when running HW_TAGS-enabled kernel built with GCC on hardware that doesn't support MTE. GCC-built kernels always have CONFIG_KASAN_STACK enabled, even though stack instrumentation isn't supported by HW_TAGS. Having that config enabled causes KASAN to issue MTE-only instructions to unpoison kernel stacks, which causes the failure. Fix the issue by disallowing CONFIG_KASAN_STACK when HW_TAGS is used. (The commit that introduced CONFIG_KASAN_HW_TAGS specified proper dependency for CONFIG_KASAN_STACK_ENABLE but not for CONFIG_KASAN_STACK.)

BACKPORT: kasan, arm64: allow using KUnit tests with HW_TAGS mode
[ Conflicts due to conflicts when reverting the FROMGIT version. ]
On a high level, this patch allows running KUnit KASAN tests with the
hardware tag-based KASAN mode.
Internally, this change reenables tag checking at the end of each KASAN
test that triggers a tag fault and leads to tag checking being disabled.
Also simplify is_write calculation in report_tag_fault.
With this patch KASAN tests are still failing for the hardware tag-based
mode; fixes come in the next few patches.

UPSTREAM: lib/vsprintf: no_hash_pointers prints all addresses as unhashed
If the no_hash_pointers command line parameter is set, then
printk("%p") will print pointers as unhashed, which is useful for
debugging purposes. This change applies to any function that uses
vsprintf, such as print_hex_dump() and seq_buf_printf().
A large warning message is displayed if this option is enabled.
Unhashed pointers expose kernel addresses, which can be a security
risk.
Also update test_printf to skip the hashed pointer tests if the
command-line option is set.

FROMGIT: kasan, mm: fail krealloc on freed objects
Currently, if krealloc() is called on a freed object with KASAN enabled, it allocates and returns a new object, but doesn't copy any memory from the old one as ksize() returns 0. This makes the caller believe that krealloc() succeeded (KASAN report is printed though). This patch adds an accessibility check into __do_krealloc(). If the check fails, krealloc() returns NULL. This check duplicates the one in ksize(); this is fixed in the following patch. This patch also adds a KASAN-KUnit test to check krealloc() behaviour when it's called on a freed object.

This patch reworks KASAN-KUnit tests for krealloc() to: 1. Check both slab and page_alloc based krealloc() implementations. 2.

FROMGIT: lib: stackdepot: add support to disable stack depot
Add a kernel parameter stack_depot_disable to disable stack depot. So that stack hash table doesn't consume any memory when stack depot is disabled. The use case is CONFIG_PAGE_OWNER without page_owner=on. Without this patch, stackdepot will consume the memory for the hashtable. By default, it's 8M which is never trivial. With this option, in CONFIG_PAGE_OWNER configured system, page_owner=off, stack_depot_disable in kernel command line, we could save the wasted memory for the hashtable.

FROMGIT: lib: stackdepot: add support to configure STACK_HASH_SIZE
Use CONFIG_STACK_HASH_ORDER to configure STACK_HASH_SIZE. Aim is to have configurable value for STACK_HASH_SIZE, so depend on use case one can configure it. One example is of Page Owner, CONFIG_PAGE_OWNER works only if page_owner=on via kernel parameter on CONFIG_PAGE_OWNER configured system. Thus, unless admin enable it via command line option, the stackdepot will just waste 8M memory without any customer. Making it configurable and use lower value helps to enable features like CONFIG_PAGE_OWNER without any significant overhead.

UPSTREAM: lib/stackdepot.c: replace one-element array with flexible-array member
Patch series "lib/stackdepot.c: Replace one-element array with flexible-array member".
This series aims to replace a one-element array with a flexible-array
member. Also, make use of the struct_size(), flexible_array_size() and
array_size() helpers.
This patch (of 3):
There is a regular need in the kernel to provide a way to declare having a
dynamically sized set of trailing elements in a structure. Kernel code
should always use “flexible array members”[1] for these cases. The
older style of one-element or zero-length arrays should no longer be
used[2].
Refactor the code according to the use of a flexible-array member in
struct stack_record, instead of a one-element array, and use the
struct_size() helper to calculate the size for the allocation.

FROMGIT: kasan: fix bug detection via ksize for HW_TAGS mode
The currently existing kasan_check_read/write() annotations are intended to be used for kernel modules that have KASAN compiler instrumentation disabled. Thus, they are only relevant for the software KASAN modes that rely on compiler instrumentation. However there's another use case for these annotations: ksize() checks that the object passed to it is indeed accessible before unpoisoning the whole object. This is currently done via __kasan_check_read(), which is compiled away for the hardware tag-based mode that doesn't rely on compiler instrumentation. This leads to KASAN missing detecting some memory corruptions. Provide another annotation called kasan_check_byte() that is available for all KASAN modes. As the implementation rename and reuse kasan_check_invalid_free(). Use this new annotation in ksize(). To avoid having ksize() as the top frame in the reported stack trace pass _RET_IP_ to __kasan_check_byte(). Also add a new ksize_uaf() test that checks that a use-after-free is detected via ksize() itself, and via plain accesses that happen later.

On a high level, this patch allows running KUnit KASAN tests with the hardware tag-based KASAN mode. Internally, this change reenables tag checking at the end of each KASAN test that triggers a tag fault and leads to tag checking being disabled. Also simplify is_write calculation in report_tag_fault. With this patch KASAN tests are still failing for the hardware tag-based mode; fixes come in the next few patches.

FROMGIT: kasan: add match-all tag tests
Add 3 new tests for tag-based KASAN modes: 1. Check that match-all pointer tag is not assigned randomly. 2. Check that 0xff works as a match-all pointer tag. 3. Check that there are no match-all memory tags. Note, that test #3 causes a significant number (255) of KASAN reports to be printed during execution for the SW_TAGS mode.

FROMGIT: kasan: add macros to simplify checking test constraints
Some KASAN tests require specific kernel configs to be enabled. Instead of copy-pasting the checks for these configs add a few helper macros and use them.
