lib/raid6/test/Makefile: Use $(pound) instead of \# for Make 4.3
[ Upstream commit 633174a7046ec3b4572bec24ef98e6ee89bce14b ]
Buidling raid6test on Ubuntu 21.10 (ppc64le) with GNU Make 4.3 shows the
errors below:
$ cd lib/raid6/test/
$ make
<stdin>:1:1: error: stray ‘\’ in program
<stdin>:1:2: error: stray ‘#’ in program
<stdin>:1:11: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ \
before ‘<’ token
[...]
The errors come from the HAS_ALTIVEC test, which fails, and the POWER
optimized versions are not built. That’s also reason nobody noticed on the
other architectures.
GNU Make 4.3 does not remove the backslash anymore. From the 4.3 release
announcment:
> * WARNING: Backward-incompatibility!
> Number signs (#) appearing inside a macro reference or function invocation
> no longer introduce comments and should not be escaped with backslashes:
> thus a call such as:
> foo := $(shell echo '#')
> is legal. Previously the number sign needed to be escaped, for example:
> foo := $(shell echo '\#')
> Now this latter will resolve to "\#". If you want to write makefiles
> portable to both versions, assign the number sign to a variable:
> H := \#
> foo := $(shell echo '$H')
> This was claimed to be fixed in 3.81, but wasn't, for some reason.
> To detect this change search for 'nocomment' in the .FEATURES variable.

lib/test: use after free in register_test_dev_kmod()
[ Upstream commit dc0ce6cc4b133f5f2beb8b47dacae13a7d283c2c ]
The "test_dev" pointer is freed but then returned to the caller.

vsprintf: Fix %pK with kptr_restrict == 0
[ Upstream commit 84842911322fc6a02a03ab9e728a48c691fe3efd ]
Although kptr_restrict is set to 0 and the kernel is booted with
no_hash_pointers parameter, the content of /proc/vmallocinfo is
lacking the real addresses.
/ # cat /proc/vmallocinfo

...
According to the documentation for /proc/sys/kernel/, %pK is
equivalent to %p when kptr_restrict is set to 0.

vsprintf: Fix potential unaligned access
[ Upstream commit d75b26f880f60ead301e79ba0f4a635c5a60767f ]
The %p4cc specifier in some cases might get an unaligned pointer.
Due to this we need to make copy to local variable once to avoid
potential crashes on some architectures due to improper access.

kunit: make kunit_test_timeout compatible with comment
[ Upstream commit bdd015f7b71b92c2e4ecabac689642cc72553e04 ]
In function kunit_test_timeout, it is declared "300 * MSEC_PER_SEC"
represent 5min. However, it is wrong when dealing with arm64 whose
default HZ = 250, or some other situations. Use msecs_to_jiffies to fix
this, and kunit_test_timeout will work as desired.

lib/raid6/test: fix multiple definition linking error
commit a5359ddd052860bacf957e65fe819c63e974b3a6 upstream. GCC 10+ defaults to -fno-common, which enforces proper declaration of external references using "extern". without this change a link would fail with: lib/raid6/test/algos.c:28: multiple definition of `raid6_call'; lib/raid6/test/test.c:22: first defined here the pq.h header that is included already includes an extern declaration so we can just remove the redundant one here.

ANDROID: GKI: set vfs-only exports into their own namespace
We have namespaces, so use them for all vfs-exported namespaces so that filesystems can use them, but not anything else. Some in-kernel drivers that do direct filesystem accesses (because they serve up files) are also allowed access to these symbols to keep 'make allmodconfig' builds working properly, but it is not needed for Android kernel images.

ARM: 9178/1: fix unmet dependency on BITREVERSE for HAVE_ARCH_BITREVERSE
[ Upstream commit 11c57c3ba94da74c3446924260e34e0b1950b5d7 ] Resending this to properly add it to the patch tracker - thanks for letting me know, Arnd :) When ARM is enabled, and BITREVERSE is disabled, Kbuild gives the following warning: WARNING: unmet direct dependencies detected for HAVE_ARCH_BITREVERSE Depends on [n]: BITREVERSE [=n] Selected by [y]: - ARM [=y] && (CPU_32v7M [=n] || CPU_32v7 [=y]) && !CPU_32v6 [=n] This is because ARM selects HAVE_ARCH_BITREVERSE without selecting BITREVERSE, despite HAVE_ARCH_BITREVERSE depending on BITREVERSE. This unmet dependency bug was found by Kismet, a static analysis tool for Kconfig. Please advise if this is not the appropriate solution.

FROMGIT: bpf: Add config to allow loading modules with BTF mismatches
BTF mismatch can occur for a separately-built module even when the ABI is otherwise compatible and nothing else would prevent successfully loading. Add a new Kconfig to control how mismatches are handled. By default, preserve the current behavior of refusing to load the module. If MODULE_ALLOW_BTF_MISMATCH is enabled, load the module but ignore its BTF information.

allocate a new pipe_buffer, but the "flags" member initializer is
missing.

Add new vmalloc-related tests: - vmalloc_helpers_tags() to check that exported vmalloc helpers can handle tagged pointers. - vmap_tags() to check that SW_TAGS mode properly tags vmap() mappings. - vm_map_ram_tags() to check that SW_TAGS mode properly tags vm_map_ram() mappings. - vmalloc_percpu() to check that SW_TAGS mode tags regions allocated for __alloc_percpu(). The tagging of per-cpu mappings is best-effort; proper tagging is tracked in [1].

UPSTREAM: kasan: test: fix compatibility with FORTIFY_SOURCE
With CONFIG_FORTIFY_SOURCE enabled, string functions will also perform dynamic checks using __builtin_object_size(ptr), which when failed will panic the kernel. Because the KASAN test deliberately performs out-of-bounds operations, the kernel panics with FORTIFY_SOURCE, for example: | kernel BUG at lib/string_helpers.c:910! | invalid opcode: 0000 [#1] PREEMPT SMP KASAN PTI | CPU: 1 PID: 137 Comm: kunit_try_catch Tainted: G B 5.16.0-rc3+ #3 | Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-2 04/01/2014 | RIP: 0010:fortify_panic+0x19/0x1b | ... | Call Trace: | kmalloc_oob_in_memset.cold+0x16/0x16 | ... Fix it by also hiding `ptr` from the optimizer, which will ensure that __builtin_object_size() does not return a valid size, preventing fortified string functions from panicking.

UPSTREAM: lib/stackdepot: always do filter_irq_stacks() in stack_depot_save()
The non-interrupt portion of interrupt stack traces before interrupt entry is usually arbitrary. Therefore, saving stack traces of interrupts (that include entries before interrupt entry) to stack depot leads to unbounded stackdepot growth. As such, use of filter_irq_stacks() is a requirement to ensure stackdepot can efficiently deduplicate interrupt stacks. Looking through all current users of stack_depot_save(), none (except KASAN) pass the stack trace through filter_irq_stacks() before passing it on to stack_depot_save(). Rather than adding filter_irq_stacks() to all current users of stack_depot_save(), it became clear that stack_depot_save() should simply do filter_irq_stacks().

UPSTREAM: kasan: test: add globals left-out-of-bounds test
Add a test checking that KASAN generic can also detect out-of-bounds accesses to the left of globals. Unfortunately it seems that GCC doesn't catch this (tested GCC 10, 11). The main difference between GCC's globals redzoning and Clang's is that GCC relies on using increased alignment to producing padding, where Clang's redzoning implementation actually adds real data after the global and doesn't rely on alignment to produce padding. I believe this is the main reason why GCC can't reliably catch globals out-of-bounds in this case. Given this is now a known issue, to avoid failing the whole test suite, skip this test case with GCC.

Intentional overflows, as performed by the KASAN tests, are detected at compile time[1] (instead of only at run-time) with the addition of __alloc_size.

Architectures supported by KASAN_HW_TAGS can provide an asymmetric mode of execution. On an MTE enabled arm64 hw for example this can be identified with the asymmetric tagging mode of execution. In particular, when such a mode is present, the CPU triggers a fault on a tag mismatch during a load operation and asynchronously updates a register when a tag mismatch is detected during a store operation.

mm/hmm.c: allow VM_MIXEDMAP to work with hmm_range_fault
commit 87c01d57fa23de82fff593a7d070933d08755801 upstream.
hmm_range_fault() can be used instead of get_user_pages() for devices
which allow faulting however unlike get_user_pages() it will return an
error when used on a VM_MIXEDMAP range.
To make hmm_range_fault() more closely match get_user_pages() remove
this restriction. This requires dealing with the !ARCH_HAS_PTE_SPECIAL
case in hmm_vma_handle_pte(). Rather than replicating the logic of
vm_normal_page() call it directly and do a check for the zero pfn
similar to what get_user_pages() currently does.
Also add a test to hmm selftest to verify functionality.

[ Upstream commit 37dbb4c7c7442dbfc9b651e4ddd4afe30b26afc9 ] It's possible that a parameterised test could end up with zero parameters. At the moment, the test function will nevertheless be called with NULL as the parameter. Instead, don't try to run the test code, and just mark the test as SKIPped.

lib/logic_iomem: Fix operation on 32-bit
[ Upstream commit 4e8a5edac5010820e7c5303fc96f5a262e096bb6 ]
On 32-bit, the first entry might be at 0/NULL, but that's
strange and leads to issues, e.g. where we check "if (ret)".
Use a IOREMAP_BIAS/IOREMAP_MASK of 0x80000000UL to avoid
this. This then requires reducing the number of areas (via
MAX_AREAS), but we still have 128 areas, which is enough.

lib/logic_iomem: Fix 32-bit build
[ Upstream commit 4e84139e14af5ea60772cc4f33d7059aec76e0eb ]
On a 32-bit build, the (unsigned long long) casts throw warnings
(or errors) due to being to a different integer size. Cast to
uintptr_t first (with the __force for sparse) and then further
to get the consistent print on 32 and 64-bit.

siphash: use _unaligned version by default
commit f7e5b9bfa6c8820407b64eabc1f29c9a87e8993d upstream.
On ARM v6 and later, we define CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS
because the ordinary load/store instructions (ldr, ldrh, ldrb) can
tolerate any misalignment of the memory address. However, load/store
double and load/store multiple instructions (ldrd, ldm) may still only
be used on memory addresses that are 32-bit aligned, and so we have to
use the CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS macro with care, or we
may end up with a severe performance hit due to alignment traps that
require fixups by the kernel. Testing shows that this currently happens
with clang-13 but not gcc-11. In theory, any compiler version can
produce this bug or other problems, as we are dealing with undefined
behavior in C99 even on architectures that support this in hardware,
see also https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100363.
Fortunately, the get_unaligned() accessors do the right thing: when
building for ARMv6 or later, the compiler will emit unaligned accesses
using the ordinary load/store instructions (but avoid the ones that
require 32-bit alignment). When building for older ARM, those accessors
will emit the appropriate sequence of ldrb/mov/orr instructions. And on
architectures that can truly tolerate any kind of misalignment, the
get_unaligned() accessors resolve to the leXX_to_cpup accessors that
operate on aligned addresses.
Since the compiler will in fact emit ldrd or ldm instructions when
building this code for ARM v6 or later, the solution is to use the
unaligned accessors unconditionally on architectures where this is
known to be fast. The _aligned version of the hash function is
however still needed to get the best performance on architectures
that cannot do any unaligned access in hardware.
This new version avoids the undefined behavior and should produce
the fastest hash on all architectures we support.

printk: restore flushing of NMI buffers on remote CPUs after NMI backtraces
commit 5d5e4522a7f404d1a96fd6c703989d32a9c9568d upstream.
printk from NMI context relies on irq work being raised on the local CPU
to print to console. This can be a problem if the NMI was raised by a
lockup detector to print lockup stack and regs, because the CPU may not
enable irqs (because it is locked up).
Introduce printk_trigger_flush() that can be called another CPU to try
to get those messages to the console, call that where printk_safe_flush
was previously called.

string: uninline memcpy_and_pad
commit 5c4e0a21fae877a7ef89be6dcc6263ec672372b8 upstream.
When building m68k:allmodconfig, recent versions of gcc generate the
following error if the length of UTS_RELEASE is less than 8 bytes.
In function 'memcpy_and_pad',
inlined from 'nvmet_execute_disc_identify' at
drivers/nvme/target/discovery.c:268:2: arch/m68k/include/asm/string.h:72:25: error:
'__builtin_memcpy' reading 8 bytes from a region of size 7
Discussions around the problem suggest that this only happens if an
architecture does not provide strlen(), if -ffreestanding is provided as
compiler option, and if CONFIG_FORTIFY_SOURCE=n. All of this is the case
for m68k. The exact reasons are unknown, but seem to be related to the
ability of the compiler to evaluate the return value of strlen() and
the resulting execution flow in memcpy_and_pad(). It would be possible
to work around the problem by using sizeof(UTS_RELEASE) instead of
strlen(UTS_RELEASE), but that would only postpone the problem until the
function is called in a similar way. Uninline memcpy_and_pad() instead
to solve the problem for good.

dyndbg: make dyndbg a known cli param
[ Upstream commit 5ca173974888368fecfb17ae6fe455df5fd2a9d2 ]
Right now dyndbg shows up as an unknown parameter if used on boot:
Unknown command line parameters: dyndbg=+p
That's because it is unknown, it doesn't sit in the __param
section, so the processing done to warn users supplying an unknown
parameter doesn't think it is legitimate.
Install a dummy handler to register it. dynamic debug needs to search
the whole command line for modules listed that are currently builtin,
so there's no real work to be done in this callback.

This patch fixes an error in the tail call limit test that caused the

report the total number of tail calls made. However, after a tail call
fall-through, the value of the R0 register is undefined. Now, all tail

lib/xz: Validate the value before assigning it to an enum variable
[ Upstream commit 4f8d7abaa413c34da9d751289849dbfb7c977d05 ] This might matter, for example, if the underlying type of enum xz_check was a signed char. In such a case the validation wouldn't have caught an unsupported header. I don't know if this problem can occur in the kernel on any arch but it's still good to fix it because some people might copy the XZ code to their own projects from Linux instead of the upstream XZ Embedded repository. This change may increase the code size by a few bytes. An alternative would have been to use an unsigned int instead of enum xz_check but using an enumeration looks cleaner.

lib/xz: Avoid overlapping memcpy() with invalid input with in-place decompression
[ Upstream commit 83d3c4f22a36d005b55f44628f46cc0d319a75e8 ] With valid files, the safety margin described in lib/decompress_unxz.c ensures that these buffers cannot overlap. But if the uncompressed size of the input is larger than the caller thought, which is possible when the input file is invalid/corrupt, the buffers can overlap. Obviously the result will then be garbage (and usually the decoder will return an error too) but no other harm will happen when such an over-run occurs. This change only affects uncompressed LZMA2 chunks and so this should have no effect on performance.

lib/xz: Add MicroLZMA decoder
MicroLZMA is a yet another header format variant where the first byte of a raw LZMA stream (without the end of stream marker) has been replaced with a bitwise-negation of the lc/lp/pb properties byte. MicroLZMA was created to be used in EROFS but can be used by other things too where wasting minimal amount of space for headers is important. This is implemented using most of the LZMA2 code as is so the amount of new code is small. The API has a few extra features compared to the XZ decoder. On the other hand, the API lacks XZ_BUF_ERROR support which is important to take into account when using this API. MicroLZMA doesn't support BCJ filters. In theory they could be added later as there are many unused/reserved values for the first byte of the compressed stream but in practice it is somewhat unlikely to happen due to a few implementation reasons.

lib/xz: Move s->lzma.len = 0 initialization to lzma_reset()
It's a more logical place even if the resetting needs to be done only once per LZMA2 stream (if lzma_reset() called in the middle of an LZMA2 stream, .len will already be 0).
