[ Upstream commit 4a7aee96200ad281a5cc4cf5c7a2e2a49d2b97b0 ]
In kasan_init_region, when k_start is not page aligned, at the begin of
for loop, k_cur = k_start & PAGE_MASK is less than k_start, and then
`va = block + k_cur - k_start` is less than block, the addr va is invalid,
because the memory address space from va to block is not alloced by
memblock_alloc, which will not be reserved by memblock_reserve later, it
will be used by other places.
As a result, memory overwriting occurs.
for example:
int __init __weak kasan_init_region(void *start, size_t size)
{
[...]
/* if say block(dcd97000) k_start(feef7400) k_end(feeff3fe) */
block = memblock_alloc(k_end - k_start, PAGE_SIZE);
[...]
for (k_cur = k_start & PAGE_MASK; k_cur < k_end; k_cur += PAGE_SIZE) {
/* at the begin of for loop
* block(dcd97000) va(dcd96c00) k_cur(feef7000) k_start(feef7400)
* va(dcd96c00) is less than block(dcd97000), va is invalid
*/
void *va = block + k_cur - k_start;
[...]
}
[...]
}
Therefore, page alignment is performed on k_start before
memblock_alloc() to ensure the validity of the VA address.

[ Upstream commit 6442d79d880cf7a2fff18779265d657fef0cce4c ]
fw_devlink can detect most overlapping/intersecting cycles. However it was
missing a few corner cases because of an incorrect optimization logic that
tries to avoid repeating cycle detection for devices that are already
marked as part of a cycle.
Here's an example provided by Xu Yang (edited for clarity):
usb
+-----+
tcpc | |
+-----+ | +--|
| |----------->|EP|
|--+ | | +--|
|EP|<-----------| |
|--+ | | B |
| | +-----+
| A | |
+-----+ |
^ +-----+ |
| | | |
+-----| C |<--+

+-----+
usb-phy
Node A (tcpc) will be populated as device 1-0050.
Node B (usb) will be populated as device 38100000.usb.
Node C (usb-phy) will be populated as device 381f0040.usb-phy.
The description below uses the notation:
consumer --> supplier
child ==> parent
1. Node C is populated as device C. No cycles detected because cycle
detection is only run when a fwnode link is converted to a device link.
2. Node B is populated as device B. As we convert B --> C into a device
link we run cycle detection and find and mark the device link/fwnode
link cycle:
C--> A --> B.EP ==> B --> C
3. Node A is populated as device A. As we convert C --> A into a device
link, we see it's already part of a cycle (from step 2) and don't run
cycle detection. Thus we miss detecting the cycle:
A --> B.EP ==> B --> A.EP ==> A
Looking at it another way, A depends on B in one way:
A --> B.EP ==> B
But B depends on A in two ways and we only detect the first:
B --> C --> A
B --> A.EP ==> A
To detect both of these, we remove the incorrect optimization attempt in
step 3 and run cycle detection even if the fwnode link from which the
device link is being created has already been marked as part of a cycle.

commit 61a348857e869432e6a920ad8ea9132e8d44c316 upstream.
In current scenario if Plug-out and Plug-In performed continuously
there could be a chance while checking for dwc->gadget_driver in
dwc3_gadget_suspend, a NULL pointer dereference may occur.
Call Stack:
CPU1: CPU2:
gadget_unbind_driver dwc3_suspend_common
dwc3_gadget_stop dwc3_gadget_suspend
dwc3_disconnect_gadget
CPU1 basically clears the variable and CPU2 checks the variable.
Consider CPU1 is running and right before gadget_driver is cleared
and in parallel CPU2 executes dwc3_gadget_suspend where it finds
dwc->gadget_driver which is not NULL and resumes execution and then
CPU1 completes execution. CPU2 executes dwc3_disconnect_gadget where
it checks dwc->gadget_driver is already NULL because of which the
NULL pointer deference occur.

commit cc509b6a47e7c8998d9e41c273191299d5d9d631 upstream.
When power is recycled in usb controller during system power management,
the controller will recognize it and switch role if role has been changed
during power lost. In current design, it will be completed in resume()
function. However, this may bring issues since usb class devices have
their pm operations too and these device's resume() functions are still
not being called at this point. When usb controller recognized host role
should be stopped, these usb class devices will be removed at this point.
But these usb class devices can't be removed in some cases, such as scsi
devices. Since scsi driver may sync data to U-disk, however it will block
there because scsi drvier can only handle pm request when is in suspended
state. Therefore, there may exist a dependency between ci_resume() and usb
class device's resume(). To break this potential dependency, we need to
handle power lost work in a workqueue.

commit f17c34ffc792bbb520e4b61baa16b6cfc7d44b13 upstream.
The OTG 1.3 spec has the feature A_ALT_HNP_SUPPORT, which tells
a device that it is connected to the wrong port. Some devices
refuse to operate if you enable that feature, because it indicates
to them that they ought to request to be connected to another port.
According to the spec this feature may be used based only the following
three conditions:
6.5.3 a_alt_hnp_support
Setting this feature indicates to the B-device that it is connected to
an A-device port that is not capable of HNP, but that the A-device does
have an alternate port that is capable of HNP.
The A-device is required to set this feature under the following conditions:
• the A-device has multiple receptacles
• the A-device port that connects to the B-device does not support HNP
• the A-device has another port that does support HNP
A check for the third and first condition is missing. Add it.

commit 2840143e393a4ddc1caab4372969ea337371168c upstream.
In case of a spurious or otherwise delayed notification it is
possible that CCI still reports the previous completion. The
UCSI spec is aware of this and provides two completion bits in
CCI, one for normal commands and one for acks. As acks and commands
alternate the notification handler can determine if the completion
bit is from the current command.
The initial UCSI code correctly handled this but the distinction
between the two completion bits was lost with the introduction of
the new API.
To fix this revive the ACK_PENDING bit for ucsi_acpi and only complete
commands if the completion bit matches.

commit c1d6708bf0d3dd976460d435373cf5abf21ce258 upstream.
If a input device is opened before hid_hw_start is called, events may
not be received from the hardware. In the case of USB-backed devices,
for example, the hid_hw_start function is responsible for filling in
the URB which is submitted when the input device is opened. If a device
is opened prematurely, polling will never start because the device will
not have been in the correct state to send the URB.
Because the wacom driver registers its input devices before calling
hid_hw_start, there is a window of time where a device can be opened
and end up in an inoperable state. Some ARM-based Chromebooks in particular
reliably trigger this bug.
This commit splits the wacom_register_inputs function into two pieces.
One which is responsible for setting up the allocated inputs (and runs
prior to hid_hw_start so that devices are ready for any input events
they may end up receiving) and another which only registers the devices
(and runs after hid_hw_start to ensure devices can be immediately opened
without issue). Note that the functions to initialize the LEDs and remotes
are also moved after hid_hw_start to maintain their own dependency chains.

commit ab41a31dd5e2681803642b6d08590b61867840ec upstream.
The xf86-input-wacom driver does not treat '0' as a valid serial
number and will drop any input report which contains an
MSC_SERIAL = 0 event. The kernel driver already takes care to
avoid sending any MSC_SERIAL event if the value of serial[0] == 0
(which is the case for devices that don't actually report a
serial number), but this is not quite sufficient.
Only the lower 32 bits of the serial get reported to userspace,
so if this portion of the serial is zero then there can still
be problems.
This commit allows the driver to report either the lower 32 bits
if they are non-zero or the upper 32 bits otherwise.

commit 0a9bab391e336489169b95cb0d4553d921302189 upstream.
Tasklets have an inherent problem with memory corruption. The function
tasklet_action_common calls tasklet_trylock, then it calls the tasklet
callback and then it calls tasklet_unlock. If the tasklet callback frees
the structure that contains the tasklet or if it calls some code that may
free it, tasklet_unlock will write into free memory.
The commits 8e14f610159d and d9a02e016aaf try to fix it for dm-crypt, but
it is not a sufficient fix and the data corruption can still happen [1].
There is no fix for dm-verity and dm-verity will write into free memory
with every tasklet-processed bio.
There will be atomic workqueues implemented in the kernel 6.9 [2]. They
will have better interface and they will not suffer from the memory
corruption problem.
But we need something that stops the memory corruption now and that can be
backported to the stable kernels. So, I'm proposing this commit that
disables tasklets in both dm-crypt and dm-verity. This commit doesn't

commit f4469f3858352ad1197434557150b1f7086762a0 upstream.
Current code uses the specified ring buffer size (either the default of 128
Kbytes or a module parameter specified value) to encompass the one page
ring buffer header plus the actual ring itself. When the page size is 4K,
carving off one page for the header isn't significant. But when the page
size is 64K on ARM64, only half of the default 128 Kbytes is left for the
actual ring. While this doesn't break anything, the smaller ring size
could be a performance bottleneck.
Fix this by applying the VMBUS_RING_SIZE macro to the specified ring buffer
size. This macro adds a page for the header, and rounds up the size to a
page boundary, using the page size for which the kernel is built. Use this
new size for subsequent ring buffer calculations. For example, on ARM64
with 64K page size and the default ring size, this results in the actual
ring being 128 Kbytes, which is intended.

commit 91b80cc5b39f00399e8e2d17527cad2c7fa535e2 upstream.
On systems with 64k page size and 512M huge page sizes, the allocation and
test succeeds but errors out at the munmap. As the comment states, munmap
will failure if its not HUGEPAGE aligned. This is due to the length of
the mapping being 1/2 the size of the hugepage causing the munmap to not
be hugepage aligned. Fix this by making the mapping length the full
hugepage if the hugepage is larger than the length of the mapping.

commit 52e63d67b5bb423b33d7a262ac7f8bd375a90145 upstream.
In order for the page table level 5 to be in use, the CPU must have the
setting enabled in addition to the CONFIG option. Check for the flag to be
set to avoid false test failures on systems that do not have this cpu flag
set.
The test does a series of mmap calls including three using the
MAP_FIXED flag and specifying an address that is 1<<47 or 1<<48. These
addresses are only available if you are using level 5 page tables,
which requires both the CPU to have the capabiltiy (la57 flag) and the
kernel to be configured. Currently the test only checks for the kernel
configuration option, so this test can still report a false positive.
Here are the three failing lines:
$ ./va_high_addr_switch | grep FAILED
mmap(ADDR_SWITCH_HINT, 2 * PAGE_SIZE, MAP_FIXED): 0xffffffffffffffff - FAILED
mmap(HIGH_ADDR, MAP_FIXED): 0xffffffffffffffff - FAILED
mmap(ADDR_SWITCH_HINT, 2 * PAGE_SIZE, MAP_FIXED): 0xffffffffffffffff - FAILED
I thought (for about a second) refactoring the test so that these three
mmap calls will only be run on systems with the level 5 page tables
available, but the whole point of the test is to check the level 5
feature...

commit 9319b647902cbd5cc884ac08a8a6d54ce111fc78 upstream.
(struct dirty_throttle_control *)->thresh is an unsigned long, but is
passed as the u32 divisor argument to div_u64(). On architectures where
unsigned long is 64 bytes, the argument will be implicitly truncated.
Use div64_u64() instead of div_u64() so that the value used in the "is
this a safe division" check is the same as the divisor.
Also, remove redundant cast of the numerator to u64, as that should happen
implicitly.
This would be difficult to exploit in memcg domain, given the ratio-based
arithmetic domain_drity_limits() uses, but is much easier in global
writeback domain with a BDI_CAP_STRICTLIMIT-backing device, using e.g.
vm.dirty_bytes=(1<<32)*PAGE_SIZE so that dtc->thresh == (1<<32)

ksm_tests was previously mmapping a region of memory, aligning the
returned pointer to a PMD boundary, then setting MADV_HUGEPAGE, but was
setting it past the end of the mmapped area due to not taking the pointer
alignment into consideration. Fix this behaviour.
Up until commit efa7df3e3bb5 ("mm: align larger anonymous mappings on THP
boundaries"), this buggy behavior was (usually) masked because the
alignment difference was always less than PMD-size. But since the
mentioned commit, `ksm_tests -H -s 100` started failing.

Oddly enough, adding debug code into test_csum_ipv6_magic() made the

The gcc manual says:
"The "memory" clobber tells the compiler that the assembly code performs
memory reads or writes to items other than those listed in the input

"
This is definitely the case for csum_ipv6_magic(). Indeed, adding the

Since we're setting the CRYPTO_TFM_REQ_MAY_BACKLOG flag on our
requests to the crypto API, crypto_aead_{encrypt,decrypt} can return
-EBUSY instead of -EINPROGRESS in valid situations. For example, when
the cryptd queue for AESNI is full (easy to trigger with an
artificially low cryptd.cryptd_max_cpu_qlen), requests will be enqueued
to the backlog but still processed. In that case, the async callback
will also be called twice: first with err == -EINPROGRESS, which it
seems we can just ignore, then with err == 0.
Compared to Sabrina's original patch this version uses the new
tls_*crypt_async_wait() helpers and converts the EBUSY to
EINPROGRESS to avoid having to modify all the error handling
paths. The handling is identical.

may exit as soon as the async crypto handler calls complete()
so any code past that point risks touching already freed data.
Try to avoid the locking and extra flags altogether.
Have the main thread hold an extra reference, this way
we can depend solely on the atomic ref counter for
synchronization.
Don't futz with reiniting the completion, either, we are now
tightly controlling when completion fires.
