Peter Zijlstra asked us to find bad annotation that blows up the lockdep
storage [1][2][3] but we could not find such annotation [4][5], and
Peter cannot give us feedback any more [6]. Since we tested this patch
on linux-next.git without problems, and keeping this problem unresolved
discourages kernel testing which is more painful, I'm sending this patch
without forever waiting for response from Peter.

The test code in scripts/test_dwarf5_support.sh is somewhat difficult
to understand, but after all, we want to check binutils >= 2.35.2
From the former discussion, the requirement for generating DWARF v5 from
C code is as follows:
- gcc + gnu as -> requires gcc 5.0+ (but 7.0+ for full support)
- clang + gnu as -> requires binutils 2.35.2+
- clang + integrated as -> OK

It can be quite useful to have ld emit a link map file, in order to
debug or verify that special sections end up where they are supposed
to, and to see what LD_DEAD_CODE_DATA_ELIMINATION manages to get rid
of.
The only reason I'm not just adding this unconditionally is that the
.map file can be rather large (several MB), and that's a waste of
space when one isn't interested in these things. Also make it depend
on CONFIG_EXPERT.

Commit 9af7706492f9 ("lib/vsprintf: Remove support for %pF and %pf in
favour of %pS and %ps") removed support for %pF and %pf, and correctly
removed the handling of those cases in vbin_printf(). However, the
corresponding cases in bstr_printf() were left behind.
In the same series, %pf was re-purposed for dealing with
fwnodes (3bd32d6a2ee6, "lib/vsprintf: Add %pfw conversion specifier
for printing fwnode names").
So should anyone use %pf with the binary printf routines,
vbin_printf() would (correctly, as it involves dereferencing the
pointer) do the string formatting to the u32 array, but bstr_printf()
would not copy the string from the u32 array, but instead interpret
the first sizeof(void*) bytes of the formatted string as a pointer -
which generally won't end well (also, all subsequent get_args would be
out of sync).

We have a need in the TPM2 trusted keys to return the ASN.1 form of the TPM
key blob so it can be operated on by tools outside of the kernel. The
specific tools are the openssl_tpm2_engine, openconnect and the Intel
tpm2-tss-engine. To do that, we have to be able to read and write the same
binary key format the tools use. The current ASN.1 decoder does fine for
reading, but we need pieces of an ASN.1 encoder to write the key blob in
binary compatible form.
For backwards compatibility, the trusted key reader code will still accept
the two TPM2B quantities that it uses today, but the writer will only
output the ASN.1 form.
The current implementation only encodes the ASN.1 bits we actually need.

This change adds KASAN-KUnit tests support for the async HW_TAGS mode.
In async mode, tag fault aren't being generated synchronously when a
bad access happens, but are instead explicitly checked for by the kernel.
As each KASAN-KUnit test expect a fault to happen before the test is over,
check for faults as a part of the test handler.

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. ]

list_sort() internally casts the comparison function passed to it
to a different type with constant struct list_head pointers, and
uses this pointer to call the functions, which trips indirect call
Control-Flow Integrity (CFI) checking.
Instead of removing the consts, this change defines the
list_cmp_func_t type and changes the comparison function types of
all list_sort() callers to use const pointers, thus avoiding type
mismatches.

ARM64 currently defaults to posted MMIO (nGnRE), but some devices
require the use of non-posted MMIO (nGnRnE). Introduce a new ioremap()
variant to handle this case. ioremap_np() returns NULL on arches that
do not implement this variant.
sparc64 is the only architecture that needs to be touched directly,
because it includes neither of the generic io.h or iomap.h headers.
This adds the IORESOURCE_MEM_NONPOSTED flag, which maps to this
variant and marks a given resource as requiring non-posted mappings.
This is implemented in the resource system because it is a SoC-level
requirement, so existing drivers do not need special-case code to pick
this ioremap variant.
Then this is implemented in devres by introducing devm_ioremap_np(),
and making devm_ioremap_resource() automatically select this variant
when the resource has the IORESOURCE_MEM_NONPOSTED flag set.

We have several modifiers for plain pointers (%p, %px and %pK) and now
also the no_hash_pointers boot parameter. The documentation should help
to choose which variant to use. Importantly, we should discourage %px
in favor of %p (with the new boot parameter when debugging), and stress
that %pK should be only used for procfs and similar files, not dmesg
buffer. This patch clarifies the documentation in that regard.

Add a kunit_fail_current_test() function to fail the currently running
test, if any, with an error message.
This is largely intended for dynamic analysis tools like UBSAN and for
fakes.
E.g. say I had a fake ops struct for testing and I wanted my `free`
function to complain if it was called with an invalid argument, or
caught a double-free. Most return void and have no normal means of
signalling failure (e.g. super_operations, iommu_ops, etc.).
Key points:
* Always update current->kunit_test so anyone can use it.
* commit 83c4e7a0363b ("KUnit: KASAN Integration") only updated it for
CONFIG_KASAN=y
* Create a new header <kunit/test-bug.h> so non-test code doesn't have
to include all of <kunit/test.h> (e.g. lib/ubsan.c)
* Forward the file and line number to make it easier to track down
failures
* Declare the helper function for nice __printf() warnings about mismatched
format strings even when KUnit is not enabled.
Example output from kunit_fail_current_test("message"):
[15:19:34] [FAILED] example_simple_test
[15:19:34] # example_simple_test: initializing
[15:19:34] # example_simple_test: lib/kunit/kunit-example-test.c:24: message

TL;DR
$ ./tools/testing/kunit/kunit.py run --kunitconfig=lib/kunit
Per suggestion from Ted [1], we can reduce the amount of typing by
assuming a convention that these files are named '.kunitconfig'.
In the case of [1], we now have
$ ./tools/testing/kunit/kunit.py run --kunitconfig=fs/ext4
Also add in such a fragment for kunit itself so we can give that as an
example more close to home (and thus less likely to be accidentally
broken).

gcc-11 points out a mismatch between the declaration and the definition

lib/crypto/poly1305-donna32.c:13:67: error: argument 2 of type ‘const u8[16]’ {aka ‘const unsigned char[16]’} with mismatched bound [-Werror=array-parameter=]

21 | void poly1305_core_setkey(struct poly1305_core_key *key, const u8 *raw_key);
This is harmless in principle, as the calling conventions are the same,
but the more specific prototype allows better type checking in the
caller.
Change the declaration to match the actual function definition.
The poly1305_simd_init() is a bit suspicious here, as it previously
had a 32-byte argument type, but looks like it needs to take the
16-byte POLY1305_BLOCK_SIZE array instead.

because there're so many flavors. Let's interpret them in pGp as well.
To be compitable with the existed format of pGp, the new introduced ones
also use '|' as the separator, then the user tools parsing pGp won't
need to make change, suggested by Matthew. The new information is
tracked onto the end of the existed one.
