71f70987f9 UPSTREAM: ubsan: remove overflow checks
Since GCC 8.0 -fsanitize=signed-integer-overflow doesn't work with
-fwrapv.  -fwrapv makes signed overflows defines and GCC essentially
disables ubsan checks.  On GCC < 8.0 -fwrapv doesn't have influence on
-fsanitize=signed-integer-overflow setting, so it kinda works but
generates false-positves and violates uaccess rules:

lib/iov_iter.o: warning: objtool: iovec_from_user()+0x22d: call to
__ubsan_handle_add_overflow() with UACCESS enabled

Disable signed overflow checks to avoid these problems.  Remove unsigned
overflow checks as well.  Unsigned overflow appeared as side effect of
commit cdf8a76fda ("ubsan: move cc-option tests into Kconfig"), but it
never worked (kernel doesn't boot).  And unsigned overflows are allowed by
C standard, so it just pointless.

65a04c1a8e UPSTREAM: ubsan: disable unsigned-overflow check for i386
Building ubsan kernels even for compile-testing introduced these
warnings in my randconfig environment:

  crypto/blake2b_generic.c:98:13: error: stack frame size of 9636 bytes in function 'blake2b_compress' [-Werror,-Wframe-larger-than=]
  static void blake2b_compress(struct blake2b_state *S,

  static void sha512_generic_block_fn(struct sha512_state *sst, u8 const *src,

  lib/crypto/curve25519-fiat32.c:312:22: error: stack frame size of 2180 bytes in function 'fe_mul_impl' [-Werror,-Wframe-larger-than=]
  static noinline void fe_mul_impl(u32 out[10], const u32 in1[10], const u32 in2[10])

  lib/crypto/curve25519-fiat32.c:444:22: error: stack frame size of 1588 bytes in function 'fe_sqr_impl' [-Werror,-Wframe-larger-than=]
  static noinline void fe_sqr_impl(u32 out[10], const u32 in1[10])

Further testing showed that this is caused by
-fsanitize=unsigned-integer-overflow, but is isolated to the 32-bit x86
architecture.

The one in blake2b immediately overflows the 8KB stack area
architectures, so better ensure this never happens by disabling the
option for 32-bit x86.

fca16257ca UPSTREAM: ubsan: remove UBSAN_MISC in favor of individual options
Make each UBSAN option individually selectable and remove UBSAN_MISC which
no longer has any purpose.  Add help text for each Kconfig, and include a
reference to the Clang sanitizer documentation.  Disable unsigned overflow
by default (not available with GCC and makes x86 unbootable with Clang).
Disable unreachable when objtool is in use (redundant and confuses things:
instrumentation appears at unreachable locations).

5eb5780afe UPSTREAM: ubsan: disable UBSAN_TRAP for all*config
Doing all*config builds attempts to build as much as possible. UBSAN_TRAP
effectively short-circuits lib/usban.c, so it should be disabled for

70e365831f UPSTREAM: ubsan: remove redundant -Wno-maybe-uninitialized
Patch series "Clean up UBSAN Makefile", v2.

This series attempts to address the issues seen with UBSAN's object-size
sanitizer causing problems under GCC.  In the process, the Kconfig and
Makefile are refactored to do all the cc-option calls in the Kconfig.
Additionally start to detangle -Wno-maybe-uninitialized, disable
UBSAN_TRAP under COMPILE_TEST for wider build coverage, and expand the
libusan tests.

This patch (of 7):

In commit 78a5255ffb ("Stop the ad-hoc games with
-Wno-maybe-initialized") -Wmaybe-uninitialized was disabled globally, so
keeping the disabling logic here too doesn't make sense.

dde7ff1c19 lib/mpi: use kcalloc in mpi_resize
[ Upstream commit b6f756726e ]

We should set the additional space to 0 in mpi_resize().
So use kcalloc() instead of kmalloc_array().

In lib/mpi/ec.c:
/****************
 * Resize the array of A to NLIMBS. the additional space is cleared
 * (set to 0) [done by m_realloc()]
 */
int mpi_resize(MPI a, unsigned nlimbs)

Like the comment of kernel's mpi_resize() said, the additional space
need to be set to 0, but when a->d is not NULL, it does not set.

The kernel's mpi lib is from libgcrypt, the mpi resize in libgcrypt
is _gcry_mpi_resize() which set the additional space to 0.

This bug may cause mpi api which use mpi_resize() get wrong result
under the condition of using the additional space without initiation.
If this condition is not met, the bug would not be triggered.
Currently in kernel, rsa, sm2 and dh use mpi lib, and they works well,
so the bug is not triggered in these cases.

add_points_edwards() use the additional space directly, so it will
get a wrong result.

This reverts commit 6815e21fe2 which is
commit 1027b96ec9 upstream.

The function __do_once_done() added a new parameter to handle the
problem when unloading modules with that function in it.  Android does
not support module unloading so just revert this as it breaks the kabi.

6815e21fe2 once: Fix panic when module unload
[ Upstream commit 1027b96ec9 ]

DO_ONCE
DEFINE_STATIC_KEY_TRUE(___once_key);
__do_once_done
  once_disable_jump(once_key);
    INIT_WORK(&w->work, once_deferred);
    struct once_work *w;
    w->key = key;
    schedule_work(&w->work);                     module unload
                                                   //*the key is
destroy*
process_one_work
  once_deferred
    BUG_ON(!static_key_enabled(work->key));
       static_key_count((struct static_key *)x)    //*access key, crash*

When module uses DO_ONCE mechanism, it could crash due to the above
concurrency problem, we could reproduce it with link[1].

Fix it by add/put module refcount in the once work process.

4a31baf55f net: add kcov handle to skb extensions
[ Upstream commit 6370cc3bbd ]

Remote KCOV coverage collection enables coverage-guided fuzzing of the
code that is not reachable during normal system call execution. It is
especially helpful for fuzzing networking subsystems, where it is
common to perform packet handling in separate work queues even for the
packets that originated directly from the user space.

Enable coverage-guided frame injection by adding kcov remote handle to
skb extensions. Default initialization in __alloc_skb and
__build_skb_around ensures that no socket buffer that was generated
during a system call will be missed.

Code that is of interest and that performs packet processing should be
annotated with kcov_remote_start()/kcov_remote_stop().

An alternative approach is to determine kcov_handle solely on the
basis of the device/interface that received the specific socket
buffer. However, in this case it would be impossible to distinguish
between packets that originated during normal background network
processes or were intentionally injected from the user space.

ff53dfb323 lib/decompress_unlz4.c: correctly handle zero-padding around initrds.
[ Upstream commit 2c484419ef ]

lz4 compatible decompressor is simple.  The format is underspecified and
relies on EOF notification to determine when to stop.  Initramfs buffer
format[1] explicitly states that it can have arbitrary number of zero
padding.  Thus when operating without a fill function, be extra careful to
ensure that sizes less than 4, or apperantly empty chunksizes are treated
as EOF.

To test this I have created two cpio initrds, first a normal one,
main.cpio.  And second one with just a single /test-file with content
"second" second.cpio.  Then i compressed both of them with gzip, and with
lz4 -l.  Then I created a padding of 4 bytes (dd if=/dev/zero of=pad4 bs=1
count=4).  To create four testcase initrds:

 1) main.cpio.gzip + extra.cpio.gzip = pad0.gzip
 2) main.cpio.lz4  + extra.cpio.lz4 = pad0.lz4
 3) main.cpio.gzip + pad4 + extra.cpio.gzip = pad4.gzip
 4) main.cpio.lz4  + pad4 + extra.cpio.lz4 = pad4.lz4

The pad4 test-cases replicate the initrd load by grub, as it pads and
aligns every initrd it loads.

All of the above boot, however /test-file was not accessible in the initrd
for the testcase #4, as decoding in lz4 decompressor failed.  Also an
error message printed which usually is harmless.

Whith a patched kernel, all of the above testcases now pass, and
/test-file is accessible.

This fixes lz4 initrd decompress warning on every boot with grub.  And
more importantly this fixes inability to load multiple lz4 compressed
initrds with grub.  This patch has been shipping in Ubuntu kernels since
January 2021.

f9fb4986f4 seq_buf: Fix overflow in seq_buf_putmem_hex()
commit d3b16034a2 upstream.

There's two variables being increased in that loop (i and j), and i
follows the raw data, and j follows what is being written into the buffer.
We should compare 'i' to MAX_MEMHEX_BYTES or compare 'j' to HEX_CHARS.
Otherwise, if 'j' goes bigger than HEX_CHARS, it will overflow the
destination buffer.

456554040e lib/math/rational.c: fix divide by zero
[ Upstream commit 65a0d3c146 ]

If the input is out of the range of the allowed values, either larger than
the largest value or closer to zero than the smallest non-zero allowed
value, then a division by zero would occur.

In the case of input too large, the division by zero will occur on the
first iteration.  The best result (largest allowed value) will be found by
always choosing the semi-convergent and excluding the denominator based
limit when finding it.

In the case of the input too small, the division by zero will occur on the
second iteration.  The numerator based semi-convergent should not be
calculated to avoid the division by zero.  But the semi-convergent vs
previous convergent test is still needed, which effectively chooses
between 0 (the previous convergent) vs the smallest allowed fraction (best
semi-convergent) as the result.

f18f7a2276 lockdep/selftests: Fix selftests vs PROVE_RAW_LOCK_NESTING
[ Upstream commit c0c2c0dad6 ]

When PROVE_RAW_LOCK_NESTING=y many of the selftests FAILED because
HARDIRQ context is out-of-bounds for spinlocks. Instead make the
default hardware context the threaded hardirq context, which preserves
the old locking rules.

The wait-type specific locking selftests will have a non-threaded
HARDIRQ variant.

5a3ac10611 locking/lockdep: Reduce LOCKDEP dependency list
[ Upstream commit b8e00abe7d ]

Some arches (um, sparc64, riscv, xtensa) cause a Kconfig warning for
LOCKDEP.
These arch-es select LOCKDEP_SUPPORT but they are not listed as one
of the arch-es that LOCKDEP depends on.

Since (16) arch-es define the Kconfig symbol LOCKDEP_SUPPORT if they
intend to have LOCKDEP support, replace the awkward list of
arch-es that LOCKDEP depends on with the LOCKDEP_SUPPORT symbol.

But wait. LOCKDEP_SUPPORT is included in LOCK_DEBUGGING_SUPPORT,
which is already a dependency here, so LOCKDEP_SUPPORT is redundant
and not needed.
That leaves the FRAME_POINTER dependency, but it is part of an
expression like this:
	depends on (A && B) && (FRAME_POINTER || B')
where B' is a dependency of B so if B is true then B' is true
and the value of FRAME_POINTER does not matter.
Thus we can also delete the FRAME_POINTER dependency.

Fixes this kconfig warning: (for um, sparc64, riscv, xtensa)

9e914f59cc lib: vsprintf: Fix handling of number field widths in vsscanf
[ Upstream commit 900fdc4573 ]

The existing code attempted to handle numbers by doing a strto[u]l(),
ignoring the field width, and then repeatedly dividing to extract the
field out of the full converted value. If the string contains a run of
valid digits longer than will fit in a long or long long, this would
overflow and no amount of dividing can recover the correct value.

This patch fixes vsscanf() to obey number field widths when parsing
the number.

A new _parse_integer_limit() is added that takes a limit for the number
of characters to parse. The number field conversion in vsscanf is changed
to use this new function.

If a number starts with a radix prefix, the field width  must be long
enough for at last one digit after the prefix. If not, it will be handled
like this:

 sscanf("0x4", "%1i", &i): i=0, scanning continues with the 'x'
 sscanf("0x4", "%2i", &i): i=0, scanning continues with the '4'

This is consistent with the observed behaviour of userland sscanf.

Note that this patch does NOT fix the problem of a single field value
overflowing the target type. So for example:

  sscanf("123456789abcdef", "%x", &i);

Will not produce the correct result because the value obviously overflows
INT_MAX. But sscanf will report a successful conversion.

Note that where a very large number is used to mean "unlimited", the value
INT_MAX is used for consistency with the behaviour of vsnprintf().

c556b938b3 seq_buf: Make trace_seq_putmem_hex() support data longer than 8
commit 6a2cbc58d6 upstream.

Since the raw memory 'data' does not go forward, it will dump repeated
data if the data length is more than 8. If we want to dump longer data
blocks, we need to repeatedly call macro SEQ_PUT_HEX_FIELD. I think it
is a bit redundant, and multiple function calls also affect the performance.

52ccdf90b9 FROMLIST: lockdep: Remove console_verbose when disable lock debugging
debug_locks_off can be called in scenarios where the kernel doesn't
immediately panic. For instance, debug_locks_off is called with a
mismatched preempt_count or when registering an improper lockdep map
and fails the sanity check for lock-class key [1]. Both of these issues
were discovered in vendor kernel code and were fixed.

When console_verbose is enabled, we have found that kernel tends to be
unstable because it is spending much of its time printing to the serial
log, so the system may miss watchdog pats. We explicitly set our system
to reduce the loglevel in order to prevent such scenarios, however
lockdep can circumvent the commandline setting. Thus, when we ran into
the kernel bugs, we first ended up trying to debug why the kernel wasn't
able to respond to watchdog pets and why it was spending all of its time
flushing the console, which did not quickly lead us to the "real"
lock dependency issue.

Remove the console_verbose when turning off lock debugging. Other debug
facilities, such as KASAN, KFENCE, SPINLOCK_DEBUG, and DEBUG_OBJECTS
don't set console_verbose when issues are detected. Current other uses
for console_verbose are in situations where kernel is in a panic path.

f20eef4d06 lib/lz4: explicitly support in-place decompression
commit 89b158635a upstream.

LZ4 final literal copy could be overlapped when doing
in-place decompression, so it's unsafe to just use memcpy()
on an optimized memcpy approach but memmove() instead.

Upstream LZ4 has updated this years ago [1] (and the impact
is non-sensible [2] plus only a few bytes remain), this commit
just synchronizes LZ4 upstream code to the kernel side as well.

It can be observed as EROFS in-place decompression failure
on specific files when X86_FEATURE_ERMS is unsupported,
memcpy() optimization of commit 59daa706fb ("x86, mem:
Optimize memcpy by avoiding memory false dependece") will
be enabled then.

Currently most modern x86-CPUs support ERMS, these CPUs just
use "rep movsb" approach so no problem at all. However, it can
still be verified with forcely disabling ERMS feature...

arch/x86/lib/memcpy_64.S:
        ALTERNATIVE_2 "jmp memcpy_orig", "", X86_FEATURE_REP_GOOD, \
-                     "jmp memcpy_erms", X86_FEATURE_ERMS
+                     "jmp memcpy_orig", X86_FEATURE_ERMS

We didn't observe any strange on arm64/arm/x86 platform before
since most memcpy() would behave in an increasing address order
("copy upwards" [3]) and it's the correct order of in-place
decompression but it really needs an update to memmove() for sure
considering it's an undefined behavior according to the standard
and some unique optimization already exists in the kernel.

a504731003 FROMLIST: bootconfig: Support mixing a value and subkeys under a key
Support mixing a value and subkeys under a key. Since kernel cmdline
options will support "aaa.bbb=value1 aaa.bbb.ccc=value2", it is
better that the bootconfig supports such configuration too.

Note that this does not change syntax itself but just accepts
mixed value and subkeys e.g.

key = value1
key.subkey = value2

But this is not accepted;

key {
 value1
 subkey = value2
}

That will make value1 as a subkey.

Also, the order of the value node under a key is fixed. If there
are a value and subkeys, the value is always the first child node
of the key. Thus if user specifies subkeys first, e.g.

key.subkey = value1
key = value2

In the program (and /proc/bootconfig), it will be shown as below

key = value2
key.subkey = value1

Picking this up FROMLIST to get the fix ASAP. It is likely to be
accepted upstream.

7559923b1a FROMLIST: bootconfig: Change array value to use child node
It is not possible to put an array value with subkeys under
a key node, because both of subkeys and the array elements
are using "next" field of the xbc_node.

Thus this changes the array values to use "child" field in
the array case. The reason why split this change is to
test it easily.

Picking this up FROMLIST to get the fix ASAP. It is likely to be
accepted upstream.

359a038bbf FROMGIT: printk: introduce dump_stack_lvl()
dump_stack() is used for many different cases, which may require a log
level consistent with other kernel messages surrounding the dump_stack()
call.  Without that, certain systems that are configured to ignore the
default level messages will miss stack traces in critical error reports.

This patch introduces dump_stack_lvl() that behaves similarly to
dump_stack(), but accepts a custom log level.  The old dump_stack()
becomes equal to dump_stack_lvl(KERN_DEFAULT).

A somewhat similar patch has been proposed in 2012:
https://lore.kernel.org/lkml/1332493269.2359.9.camel@hebo/ , but wasn't
merged.

20530f7fde kobject_uevent: remove warning in init_uevent_argv()
commit b4104180a2 upstream.

syzbot can trigger the WARN() in init_uevent_argv() which isn't the
nicest as the code does properly recover and handle the error.  So
change the WARN() call to pr_warn() and provide some more information on
what the buffer size that was needed.

fe5c0a63ad kasan: fix unit tests with CONFIG_UBSAN_LOCAL_BOUNDS enabled
commit f649dc0e0d upstream.

These tests deliberately access these arrays out of bounds, which will
cause the dynamic local bounds checks inserted by
CONFIG_UBSAN_LOCAL_BOUNDS to fail and panic the kernel.  To avoid this
problem, access the arrays via volatile pointers, which will prevent the
compiler from being able to determine the array bounds.

These accesses use volatile pointers to char (char *volatile) rather than
the more conventional pointers to volatile char (volatile char *) because
we want to prevent the compiler from making inferences about the pointer
itself (i.e.  its array bounds), not the data that it refers to.

d6c635a8cc net: fix nla_strcmp to handle more then one trailing null character
[ Upstream commit 2c16db6c92 ]

Android userspace has been using TCA_KIND with a char[IFNAMESIZ]
many-null-terminated buffer containing the string 'bpf'.

This works on 4.19 and ceases to work on 5.10.

I'm not entirely sure what fixes tag to use, but I think the issue
was likely introduced in the below mentioned 5.4 commit.
