aec6244f8b BACKPORT: lib/vdso: Enable common headers
The vDSO library should only include the necessary headers required for
a userspace library (UAPI and a minimal set of kernel headers). To make
this possible it is necessary to isolate from the kernel headers the
common parts that are strictly necessary to build the library.

Refactor the unified vdso code to use the common headers.

ca48e5d84c UPSTREAM: lib/vdso: Make clock_getres() POSIX compliant again
A recent commit removed the NULL pointer check from the clock_getres()
implementation causing a test case to fault.

POSIX requires an explicit NULL pointer check for clock_getres() aside of
the validity check of the clock_id argument for obscure reasons.

Add it back for both 32bit and 64bit.

Note, this is only a partial revert of the offending commit which does not
bring back the broken fallback invocation in the the 32bit compat
implementations of clock_getres() and clock_gettime().

28652a9b58 UPSTREAM: lib/vdso/32: Provide legacy syscall fallbacks
To address the regression which causes seccomp to deny applications the
access to clock_gettime64() and clock_getres64() syscalls because they
are not enabled in the existing filters.

That trips over the fact that 32bit VDSOs use the new clock_gettime64() and
clock_getres64() syscalls in the fallback path.

Add a conditional to invoke the 32bit legacy fallback syscalls instead of
the new 64bit variants. The conditional can go away once all architectures
are converted.

7deebec2f3 UPSTREAM: lib/vdso/32: Remove inconsistent NULL pointer checks
The 32bit variants of vdso_clock_gettime()/getres() have a NULL pointer
check for the timespec pointer. That's inconsistent vs. 64bit.

But the vdso implementation will never be consistent versus the syscall
because the only case which it can handle is NULL. Any other invalid
pointer will cause a segfault. So special casing NULL is not really useful.

Remove it along with the superflouos syscall fallback invocation as that
will return -EFAULT anyway. That also gets rid of the dubious typecast
which only works because the pointer is NULL.

941fb316b4 UPSTREAM: lib/vdso: Make delta calculation work correctly
The x86 vdso implementation on which the generic vdso library is based on
has subtle (unfortunately undocumented) twists:

 1) The code assumes that the clocksource mask is U64_MAX which means that
    no bits are masked. Which is true for any valid x86 VDSO clocksource.
    Stupidly it still did the mask operation for no reason and at the wrong
    place right after reading the clocksource.

 2) It contains a sanity check to catch the case where slightly
    unsynchronized TSC values can be observed which would cause the delta
    calculation to make a huge jump. It therefore checks whether the
    current TSC value is larger than the value on which the current
    conversion is based on. If it's not larger the base value is used to
    prevent time jumps.

reason it is also completely wrong for clocksources with a smaller mask
which can legitimately wrap around during a conversion period. The core
timekeeping code does it correct by applying the mask after the delta
calculation:

	(now - base) & mask

around during a conversion period because there the now > base check is
just wrong and causes stale time stamps and time going backwards issues.

Unbreak it by:

  1) Removing the mask operation from the clocksource read which makes the
     fallback detection work for all clocksources

  2) Replacing the conditional delta calculation with a overrideable inline
     function.

results in a significant performance hit for the x86 VSDO. The timekeeping
core code must have the non optimized version as it has to operate
correctly with clocksources which have smaller masks as well to handle the
case where TSC is discarded as timekeeper clocksource and replaced by HPET
or pmtimer. For the VDSO there is no replacement clocksource. If TSC is
unusable the syscall is enforced which does the right thing.

To accommodate to the needs of various architectures provide an
override-able inline function which defaults to the regular delta
calculation with masking:

	(now - base) & mask

Override it for x86 with the non-masking and checking version.

This unbreaks the ARM64 syscall fallback operation, allows to use
clocksources with arbitrary width and preserves the performance
optimization for x86.

4e7e5eab74 UPSTREAM: lib/vdso: Provide generic VDSO implementation
In the last few years the kernel gained quite some architecture specific
vdso implementations which contain very similar code.

Introduce a generic VDSO implementation of gettimeofday() which will be
shareable between architectures once they are converted over.

The implementation is based on the current x86 VDSO code.

00dd1df3c2 lib/raid6: use vdupq_n_u8 to avoid endianness warnings
commit 1ad3935b39 upstream.

Clang warns: vector initializers are not compatible with NEON intrinsics
in big endian mode [-Wnonportable-vector-initialization]

While this is usually the case, it's not an issue for this case since
we're initializing the uint8x16_t (16x uint8_t's) with the same value.

Instead, use vdupq_n_u8 which both compilers lower into a single movi
instruction: https://godbolt.org/z/vBrgzt

This avoids the static storage for a constant value.

9af535dc01 uapi: rename ext2_swab() to swab() and share globally in swab.h
[ Upstream commit d5767057c9 ]

ext2_swab() is defined locally in lib/find_bit.c However it is not
specific to ext2, neither to bitmaps.

There are many potential users of it, so rename it to just swab() and
move to include/uapi/linux/swab.h

ABI guarantees that size of unsigned long corresponds to BITS_PER_LONG,
therefore drop unneeded cast.

4052265b8b FROMLIST: lib: test_stackinit.c: XFAIL switch variable init tests
The tests for initializing a variable defined between a switch
statement's test and its first "case" statement are currently not
initialized in Clang[1] nor the proposed auto-initialization feature in
GCC.

We should retain the test (so that we can evaluate compiler fixes),
but mark it as an "expected fail". The rest of the kernel source will
be adjusted to avoid this corner case.

Also disable -Wswitch-unreachable for the test so that the intentionally
broken code won't trigger warnings for GCC (nor future Clang) when
initialization happens this unhandled place.

da3418ad74 lib/stackdepot.c: fix global out-of-bounds in stack_slabs
[ Upstream commit 305e519ce4 ]

Walter Wu has reported a potential case in which init_stack_slab() is
called after stack_slabs[STACK_ALLOC_MAX_SLABS - 1] has already been
initialized.  In that case init_stack_slab() will overwrite
stack_slabs[STACK_ALLOC_MAX_SLABS], which may result in a memory
corruption.

acaf62810c lib/scatterlist.c: adjust indentation in __sg_alloc_table
[ Upstream commit 4e456fee21 ]

Clang warns:

  ../lib/scatterlist.c:314:5: warning: misleading indentation; statement
  is not part of the previous 'if' [-Wmisleading-indentation]
                          return -ENOMEM;
                          ^
  ../lib/scatterlist.c:311:4: note: previous statement is here
                          if (prv)
                          ^
  1 warning generated.

This warning occurs because there is a space before the tab on this
line.  Remove it so that the indentation is consistent with the Linux
kernel coding style and clang no longer warns.

91b8348cb1 UPSTREAM: lib/test_stackinit: Handle Clang auto-initialization pattern
Upstream commit 8c30d32b1a ("lib/test_stackinit: Handle Clang
auto-initialization pattern").

While the gcc plugin for automatic stack variable initialization (i.e.
CONFIG_GCC_PLUGIN_STRUCTLEAK_BYREF_ALL) performs initialization with
0x00 bytes, the Clang automatic stack variable initialization (i.e.
CONFIG_INIT_STACK_ALL) uses various type-specific patterns that are
typically 0xAA. Therefore the stackinit selftest has been fixed to check
that bytes are no longer the test fill pattern of 0xFF (instead of looking
for bytes that have become 0x00). This retains the test coverage for the
0x00 pattern of the gcc plugin while adding coverage for the mostly 0xAA
pattern of Clang.

f6a291e73a UPSTREAM: lib: Introduce test_stackinit module
Upstream commit 50ceaa95ea ("lib: Introduce test_stackinit module").

Adds test for stack initialization coverage. We have several build options
that control the level of stack variable initialization. This test lets us
visualize which options cover which cases, and provide tests for some of
the pathological padding conditions the compiler will sometimes fail to
initialize.

All options pass the explicit initialization cases and the partial
initializers (even with padding):

test_stackinit: u8_zero ok
test_stackinit: u16_zero ok
test_stackinit: u32_zero ok
test_stackinit: u64_zero ok
test_stackinit: char_array_zero ok
test_stackinit: small_hole_zero ok
test_stackinit: big_hole_zero ok

test_stackinit: big_hole_dynamic_partial ok
test_stackinit: trailing_hole_dynamic_partial ok
test_stackinit: packed_dynamic_partial ok
test_stackinit: small_hole_static_partial ok
test_stackinit: big_hole_static_partial ok
test_stackinit: trailing_hole_static_partial ok
test_stackinit: packed_static_partial ok
test_stackinit: packed_static_all ok
test_stackinit: packed_dynamic_all ok
test_stackinit: packed_runtime_all ok

The results of the other tests (which contain no explicit initialization),
change based on the build's configured compiler instrumentation.

No options:

test_stackinit: small_hole_static_all FAIL (uninit bytes: 3)
test_stackinit: big_hole_static_all FAIL (uninit bytes: 61)

d936a940f4 UPSTREAM: dynamic_debug: allow to work if debugfs is disabled
With the realization that having debugfs enabled on "production" systems
is generally not a good idea, debugfs is being disabled from more and
more platforms over time.  However, the functionality of dynamic
debugging still is needed at times, and since it relies on debugfs for
its user api, having debugfs disabled also forces dynamic debug to be
disabled.

To get around this, also create the "control" file for dynamic_debug in
procfs.  This allows people turn on debugging as needed at runtime for
individual driverfs and subsystems.

When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.

359cc3bca0 lib/test_kasan.c: fix memory leak in kmalloc_oob_krealloc_more()
commit 3e21d9a501 upstream.

In case memory resources for _ptr2_ were allocated, release them before
return.

Notice that in case _ptr1_ happens to be NULL, krealloc() behaves
exactly like kmalloc().

Linus Torvalds
d9711896dd Partially revert "kfifo: fix kfifo_alloc() and kfifo_init()"
[ Upstream commit ab9bb6318b ]

Commit dfe2a77fd2 ("kfifo: fix kfifo_alloc() and kfifo_init()") made
the kfifo code round the number of elements up.  That was good for
__kfifo_alloc(), but it's actually wrong for __kfifo_init().

The difference? __kfifo_alloc() will allocate the rounded-up number of
elements, but __kfifo_init() uses an allocation done by the caller.  We
can't just say "use more elements than the caller allocated", and have
to round down.

The good news? All the normal cases will be using power-of-two arrays
anyway, and most users of kfifo's don't use kfifo_init() at all, but one
of the helper macros to declare a KFIFO that enforce the proper
power-of-two behavior.  But it looks like at least ibmvscsis might be
affected.

The bad news? Will Deacon refers to an old thread and points points out
that the memory ordering in kfifo's is questionable.  See

  https://lore.kernel.org/lkml/20181211034032.32338-1-yuleixzhang@tencent.com/

for more.

0fea8f5ee0 devres: allow const resource arguments
[ Upstream commit 9dea44c914 ]

devm_ioremap_resource() does not currently take 'const' arguments,
which results in a warning from the first driver trying to do it
anyway:

drivers/gpio/gpio-amd-fch.c: In function 'amd_fch_gpio_probe':
drivers/gpio/gpio-amd-fch.c:171:49: error: passing argument 2 of 'devm_ioremap_resource' discards 'const' qualifier from pointer target type [-Werror=discarded-qualifiers]
  priv->base = devm_ioremap_resource(&pdev->dev, &amd_fch_gpio_iores);
                                                 ^~~~~~~~~~~~~~~~~~~

Change the prototype to allow it, as there is no real reason not to.

4dcb40753b UPSTREAM: lib/test_meminit.c: add bulk alloc/free tests
Upstream commit dc5c5ad79f ("lib/test_meminit.c: add bulk alloc/free
tests").

kmem_cache_alloc_bulk/kmem_cache_free_bulk are used to make multiple
allocations of the same size to avoid the overhead of multiple
kmalloc/kfree calls.  Extend the kmem_cache tests to make some calls to
these APIs.

877fb9d674 UPSTREAM: kcov: improve CONFIG_ARCH_HAS_KCOV help text
(Upstream commit 40453c4f9bb6d166a56a102a8c51dd24b0801557.)

The help text for CONFIG_ARCH_HAS_KCOV is stale, and describes the
feature as being enabled only for x86_64, when it is now enabled for
several architectures, including arm, arm64, powerpc, and s390.

Let's remove that stale help text, and update it along the lines of hat
for ARCH_HAS_FORTIFY_SOURCE, better describing when an architecture
should select CONFIG_ARCH_HAS_KCOV.

0cec640db8 idr: Fix idr_get_next_ul race with idr_remove
[ Upstream commit 5a74ac4c4a ]

Commit 5c089fd0c7 ("idr: Fix idr_get_next race with idr_remove")
neglected to fix idr_get_next_ul().  As far as I can tell, nobody's
actually using this interface under the RCU read lock, but fix it now
before anybody decides to use it.

458f77a499 lib: raid6: fix awk build warnings
commit 702600eef7 upstream.

Newer versions of awk spit out these fun warnings:
	awk: ../lib/raid6/unroll.awk:16: warning: regexp escape sequence `\#' is not a known regexp operator

As commit 700c1018b8 ("x86/insn: Fix awk regexp warnings") showed, it
turns out that there are a number of awk strings that do not need to be
escaped and newer versions of awk now warn about this.

Fix the string up so that no warning is produced.  The exact same kernel
module gets created before and after this patch, showing that it wasn't
needed.

6a471a2665 lib/genalloc.c: include vmalloc.h
[ Upstream commit 35004f2e55 ]

Fixes build break on most ARM/ARM64 defconfigs:

  lib/genalloc.c: In function 'gen_pool_add_virt':
  lib/genalloc.c:190:10: error: implicit declaration of function 'vzalloc_node'; did you mean 'kzalloc_node'?
  lib/genalloc.c:190:8: warning: assignment to 'struct gen_pool_chunk *' from 'int' makes pointer from integer without a cast [-Wint-conversion]
  lib/genalloc.c: In function 'gen_pool_destroy':
  lib/genalloc.c:254:3: error: implicit declaration of function 'vfree'; did you mean 'kfree'?

0321fe1cdd lib/genalloc.c: use vzalloc_node() to allocate the bitmap
[ Upstream commit 6862d2fc81 ]

Some devices may have big memory on chip, such as over 1G.  In some
cases, the nbytes maybe bigger then 4M which is the bounday of the
memory buddy system (4K default).

So use vzalloc_node() to allocate the bitmap.  Also use vfree to free
it.
