Radxa ROCK Pi S have optional onboard SD NAND on board revision v1.1,

The optional SD NAND typically fails to initialize:
mmc_host mmc0: Bus speed (slot 0) = 400000Hz (slot req 400000Hz, actual 400000HZ div = 0)
mmc0: error -110 whilst initialising SD card

commit bf14ed81f5 upstream.
Since commit 5d0a661d80 ("mm/page_alloc: use only one PCP list for
THP-sized allocations") no longer differentiates the migration type of
pages in THP-sized PCP list, it's possible that non-movable allocation
requests may get a CMA page from the list, in some cases, it's not
acceptable.
If a large number of CMA memory are configured in system (for example, the
CMA memory accounts for 50% of the system memory), starting a virtual
machine with device passthrough will get stuck. During starting the
virtual machine, it will call pin_user_pages_remote(..., FOLL_LONGTERM,
...) to pin memory. Normally if a page is present and in CMA area,
pin_user_pages_remote() will migrate the page from CMA area to non-CMA
area because of FOLL_LONGTERM flag. But if non-movable allocation
requests return CMA memory, migrate_longterm_unpinnable_pages() will
migrate a CMA page to another CMA page, which will fail to pass the check
in check_and_migrate_movable_pages() and cause migration endless.
Call trace:
pin_user_pages_remote
--__gup_longterm_locked // endless loops in this function
----_get_user_pages_locked
----check_and_migrate_movable_pages
------migrate_longterm_unpinnable_pages
--------alloc_migration_target
This problem will also have a negative impact on CMA itself. For example,
when CMA is borrowed by THP, and we need to reclaim it through cma_alloc()
or dma_alloc_coherent(), we must move those pages out to ensure CMA's
users can retrieve that contigous memory. Currently, CMA's memory is
occupied by non-movable pages, meaning we can't relocate them. As a
result, cma_alloc() is more likely to fail.
To fix the problem above, we add one PCP list for THP, which will not
introduce a new cacheline for struct per_cpu_pages. THP will have 2 PCP
lists, one PCP list is used by MOVABLE allocation, and the other PCP list
is used by UNMOVABLE allocation. MOVABLE allocation contains GPF_MOVABLE,
and UNMOVABLE allocation contains GFP_UNMOVABLE and GFP_RECLAIMABLE.

commit d3882564a7 upstream.
Using sys_io_pgetevents() as the entry point for compat mode tasks
works almost correctly, but misses the sign extension for the min_nr
and nr arguments.
This was addressed on parisc by switching to
compat_sys_io_pgetevents_time64() in commit 6431e92fc8 ("parisc:
io_pgetevents_time64() needs compat syscall in 32-bit compat mode"),
as well as by using more sophisticated system call wrappers on x86 and
s390. However, arm64, mips, powerpc, sparc and riscv still have the
same bug.
Change all of them over to use compat_sys_io_pgetevents_time64()
like parisc already does. This was clearly the intention when the
function was originally added, but it got hooked up incorrectly in
the tables.

The old ftruncate() syscall, using the 32-bit off_t misses a sign

result, passing a negative length accidentally succeeds in truncating
to file size between 2GiB and 4GiB.
Changing the type of the compat syscall to the signed compat_off_t
changes the behavior so it instead returns -EINVAL.
The native entry point, the truncate() syscall and the corresponding
loff_t based variants are all correct already and do not suffer
from this mistake.

commit d8fb63e46c upstream.
When the mcp251xfd_start_xmit() function fails, the driver stops
processing messages, and the interrupt routine does not return,
running indefinitely even after killing the running application.
Error messages:
[ 441.298819] mcp251xfd spi2.0 can0: ERROR in mcp251xfd_start_xmit: -16
[ 441.306498] mcp251xfd spi2.0 can0: Transmit Event FIFO buffer not empty. (seq=0x000017c7, tef_tail=0x000017cf, tef_head=0x000017d0, tx_head=0x000017d3).
... and repeat forever.
The issue can be triggered when multiple devices share the same SPI
interface. And there is concurrent access to the bus.
The problem occurs because tx_ring->head increments even if
mcp251xfd_start_xmit() fails. Consequently, the driver skips one TX
package while still expecting a response in
mcp251xfd_handle_tefif_one().
Resolve the issue by starting a workqueue to write the tx obj
synchronously if err = -EBUSY. In case of another error, decrement
tx_ring->head, remove skb from the echo stack, and drop the message.

commit 537a350d14 upstream.
The internal handling of VLAN IDs in batman-adv is only specified for
following encodings:
* VLAN is used
- bit 15 is 1
- bit 11 - bit 0 is the VLAN ID (0-4095)
- remaining bits are 0
* No VLAN is used
- bit 15 is 0
- remaining bits are 0
batman-adv was only preparing new translation table entries (based on its
soft interface information) using this encoding format. But the receive
path was never checking if entries in the roam or TT TVLVs were also
following this encoding.
It was therefore possible to create more than the expected maximum of 4096
+ 1 entries in the originator VLAN list. Simply by setting the "remaining
bits" to "random" values in corresponding TVLV.

In the past, there were similar failures reported by CI from other IGT
tests, observed on other platforms.
Before commit 63baf4f3d5 ("drm/i915/gt: Only wait for GPU activity
before unbinding a GGTT fence"), i915_vma_revoke_fence() was waiting for
idleness of vma->active via fence_update(). That commit introduced
vma->fence->active in order for the fence_update() to be able to wait
selectively on that one instead of vma->active since only idleness of
fence registers was needed. But then, another commit 0d86ee3509
("drm/i915/gt: Make fence revocation unequivocal") replaced the call to
fence_update() in i915_vma_revoke_fence() with only fence_write(), and
also added that GEM_BUG_ON(!i915_active_is_idle(&fence->active)) in front.
No justification was provided on why we might then expect idleness of
vma->fence->active without first waiting on it.
The issue can be potentially caused by a race among revocation of fence
registers on one side and sequential execution of signal callbacks invoked
on completion of a request that was using them on the other, still
processed in parallel to revocation of those fence registers. Fix it by
waiting for idleness of vma->fence->active in i915_vma_revoke_fence().

Additionally, DMA memory is assumed to by contiguous in physical
address space, which is not guaranteed by vmalloc().
Resolve this by checking the module flag drm_leak_fbdev_smem when
DRM allocated the instance of struct fb_info. Fbdev-dma then only
sets smem_start only if required (via FBINFO_HIDE_SMEM_START). Also
guarantee that the framebuffer is not located in vmalloc address
space.

<mripard@kernel.org>, Thomas Zimmermann <tzimmermann@suse.de>
filp->pid is supposed to be a refcounted pointer; however, before this
patch, drm_file_update_pid() only increments the refcount of a struct
pid after storing a pointer to it in filp->pid and dropping the
dev->filelist_mutex, making the following race possible:
process A process B
========= =========
begin drm_file_update_pid
mutex_lock(&dev->filelist_mutex)
rcu_replace_pointer(filp->pid, <pid B>, 1)
mutex_unlock(&dev->filelist_mutex)
begin drm_file_update_pid
mutex_lock(&dev->filelist_mutex)
rcu_replace_pointer(filp->pid, <pid A>, 1)
mutex_unlock(&dev->filelist_mutex)
get_pid(<pid A>)
synchronize_rcu()
put_pid(<pid B>) *** pid B reaches refcount 0 and is freed here ***
get_pid(<pid B>) *** UAF ***
synchronize_rcu()
put_pid(<pid A>)
As far as I know, this race can only occur with CONFIG_PREEMPT_RCU=y
because it requires RCU to detect a quiescent state in code that is not
explicitly calling into the scheduler.
This race leads to use-after-free of a "struct pid".
It is probably somewhat hard to hit because process A has to pass
through a synchronize_rcu() operation while process B is between
mutex_unlock() and get_pid().
Fix it by ensuring that by the time a pointer to the current task's pid
is stored in the file, an extra reference to the pid has been taken.
This fix also removes the condition for synchronize_rcu(); I think
that optimization is unnecessary complexity, since in that case we
would usually have bailed out on the lockless check above.

fadvise64_64() has two 64-bit arguments at the wrong alignment

The downstream musl port for hexagon actually asks for a 6-argument

commit 3339b99ef6 upstream.
Both of these architectures require u64 function arguments to be
passed in even/odd pairs of registers or stack slots, which in case of
sync_file_range would result in a seven-argument system call that is
not currently possible. The system call is therefore incompatible with
all existing binaries.
While it would be possible to implement support for seven arguments
like on mips, it seems better to use a six-argument version, either
with the normal argument order but misaligned as on most architectures
or with the reordered sync_file_range2() calling conventions as on
arm and powerpc.

commit b9fd2affe4 upstream.
When creating a new block group, it calls btrfs_add_new_free_space() to add
the entire block group range into the free space accounting.
__btrfs_add_free_space_zoned() checks if size == block_group->length to
detect the initial free space adding, and proceed that case properly.
However, if the zone_capacity == zone_size and the over-write speed is fast
enough, the entire zone can be over-written within one transaction. That
confuses __btrfs_add_free_space_zoned() to handle it as an initial free
space accounting. As a result, that block group becomes a strange state: 0
used bytes, 0 zone_unusable bytes, but alloc_offset == zone_capacity (no
allocation anymore).
The initial free space accounting can properly be checked by checking
alloc_offset too.

commit 30766f1105 upstream.
The unusual function calling conventions on SuperH ended up causing
sync_file_range to have the wrong argument order, with the 'flags'
argument getting sorted before 'nbytes' by the compiler.
In userspace, I found that musl, glibc, uclibc and strace all expect the
normal calling conventions with 'nbytes' last, so changing the kernel
to match them should make all of those work.
In order to be able to also fix libc implementations to work with existing
kernels, they need to be able to tell which ABI is used. An easy way
to do this is to add yet another system call using the sync_file_range2
ABI that works the same on all architectures.
Old user binaries can now work on new kernels, and new binaries can
try the new sync_file_range2() to work with new kernels or fall back
to the old sync_file_range() version if that doesn't exist.

The liointc hardware provides separate Interrupt Status Registers (ISR) for
each core. The current code uses always the ISR of core #0, which works
during boot because by default all interrupts are routed to core #0.
When the interrupt routing changes in the firmware configuration then this
causes interrupts to be lost because they are not configured in the
corresponding core.
Use the core index to access the correct ISR instead of a hardcoded 0.

commit 2d64eaeeed upstream.
Multi-bridge machines required that all eiointc controllers in the system
are initialized, otherwise the system does not boot.
The initialization happens on the boot CPU during early boot and relies on
cpu_to_node() for identifying the individual nodes.
That works when the number of possible CPUs is large enough, but with a
command line limit, e.g. "nr_cpus=$N" for kdump, but fails when the CPUs
of the secondary nodes are not covered.
During early ACPI enumeration all CPU to node mappings are recorded up to
CONFIG_NR_CPUS. These are accessible via early_cpu_to_node() even in the
case that "nr_cpus=N" truncates the number of possible CPUs and only
provides the possible CPUs via cpu_to_node() translation.
Change the node lookup in the driver to use early_cpu_to_node() so that
even with a limitation on the number of possible CPUs all eointc instances
are initialized.
This can't obviously cure the case where CONFIG_NR_CPUS is too small.

commit a1ff59784b upstream.
It is reported that single-thread performance on some hybrid systems
dropped significantly after commit 7feec7430e ("ACPI: CPPC: Only probe
for _CPC if CPPC v2 is acked") which prevented _CPC from being used if
the support for it had not been confirmed by the platform firmware.
The problem is that if the platform firmware does not confirm CPPC v2
support, cppc_get_perf_caps() returns an error which prevents the
intel_pstate driver from enabling ITMT. Consequently, the scheduler
does not get any hints on CPU performance differences, so in a hybrid
system some tasks may run on CPUs with lower capacity even though they
should be running on high-capacity CPUs.
To address this, modify intel_pstate to use the information from
MSR_HWP_CAPABILITIES to enable ITMT if CPPC is not available (which is
done already if the highest performance number coming from CPPC is not
realistic).

This patch enhances error handling in scenarios with RTS (Request to

Previously, sessions were only released at the end of j1939_xtp_rx_rts().
Potentially this could be reproduced with something like:
testj1939 -r vcan0:0x80 &
while true; do
# send first RTS

commit 8e1ec117ef upstream.
Sometimes errors are seen, when doing DR swap, like:
[ 24.672481] ucsi-stm32g0-i2c 0-0035: UCSI_GET_PDOS failed (-5)
[ 24.720188] ucsi-stm32g0-i2c 0-0035: ucsi_handle_connector_change:
GET_CONNECTOR_STATUS failed (-5)
There may be some race, which lead to read CCI, before the command complete
flag is set, hence returning -EIO. Similar fix has been done also in
ucsi_acpi [1].
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.
To fix this add the ACK_PENDING bit for ucsi_stm32g0 and only complete
commands if the completion bit matches.

The device_for_each_child_node() macro requires explicit calls to
fwnode_handle_put() in all early exits of the loop if the child node is
not required outside. Otherwise, the child node's refcount is not
decremented and the resource is not released.
The current implementation of pmic_glink_ucsi_probe() makes use of the
device_for_each_child_node(), but does not release the child node on
early returns. Add the missing calls to fwnode_handle_put().
