mm: percpu: increase PERCPU_DYNAMIC_SIZE_SHIFT on certain builds.
Arnd reported a build failure due to the BUILD_BUG_ON() statement in
alloc_kmem_cache_cpus(). The test
PERCPU_DYNAMIC_EARLY_SIZE < NR_KMALLOC_TYPES * KMALLOC_SHIFT_HIGH * sizeof(struct kmem_cache_cpu)
The factors that increase the right side of the equation:
- PAGE_SIZE > 4KiB increases KMALLOC_SHIFT_HIGH
- For the local_lock_t in kmem_cache_cpu:
- PREEMPT_RT adds an actual lock.
- LOCKDEP increases the size of the lock.
- LOCK_STAT adds additional bytes plus padding to the lockdep
structure.
The net difference with and without PREEMPT_RT is 88 bytes for the
lock_lock_t, 96 bytes for kmem_cache_cpu due to additional padding. This
is enough to exceed the 80KiB limit with 16KiB page size - the 8KiB page
size is fine.
Increase PERCPU_DYNAMIC_SIZE_SHIFT to 13 on configs with PAGE_SIZE larger
than 4KiB and LOCKDEP enabled.

selftests/mm: replace atomic_bool with pthread_barrier_t
Patch series "selftests/mm: fix deadlock after pthread_create". On Android arm, pthread_create followed by a fork caused a deadlock in the case where the fork required work to be completed by the created thread. Update the synchronization primitive to use pthread_barrier instead of atomic_bool. Apply the same fix to the wp-fork-with-event test. This patch (of 2): Swap synchronization primitive with pthread_barrier, so that stdatomic.h does not need to be included. The synchronization is needed on Android ARM64; we see a deadlock with pthread_create when the parent thread races forward before the child has a chance to start doing work.

nilfs2: propagate directory read errors from nilfs_find_entry()
Syzbot reported that a task hang occurs in vcs_open() during a fuzzing test for nilfs2. The root cause of this problem is that in nilfs_find_entry(), which searches for directory entries, ignores errors when loading a directory page/folio via nilfs_get_folio() fails. If the filesystem images is corrupted, and the i_size of the directory inode is large, and the directory page/folio is successfully read but fails the sanity check, for example when it is zero-filled, nilfs_check_folio() may continue to spit out error messages in bursts. Fix this issue by propagating the error to the callers when loading a page/folio fails in nilfs_find_entry(). The current interface of nilfs_find_entry() and its callers is outdated and cannot propagate error codes such as -EIO and -ENOMEM returned via nilfs_find_entry(), so fix it together.

mm/mmap: correct error handling in mmap_region()
Commit f8d112a4e657 ("mm/mmap: avoid zeroing vma tree in mmap_region()")
changed how error handling is performed in mmap_region().
The error value defaults to -ENOMEM, but then gets reassigned immediately
to the result of vms_gather_munmap_vmas() if we are performing a MAP_FIXED
mapping over existing VMAs (and thus unmapping them).
This overwrites the error value, potentially clearing it.
After this, we invoke may_expand_vm() and possibly vm_area_alloc(), and
check to see if they failed. If they do so, then we perform error-handling
logic, but importantly, we do NOT update the error code.
This means that, if vms_gather_munmap_vmas() succeeds, but one of these
calls does not, the function will return indicating no error, but rather an
address value of zero, which is entirely incorrect.
Correct this and avoid future confusion by strictly setting error on each
and every occasion we jump to the error handling logic, and set the error
code immediately prior to doing so.
This way we can see at a glance that the error code is always correct.
Many thanks to Vegard Nossum who spotted this issue in discussion around
this problem.

Pull fbdev platform driver fix from Helge Deller:
"Switch fbdev drivers back to struct platform_driver::remove()
Now that 'remove()' has been converted to the sane new API, there's
no reason for the 'remove_new()' use, so this converts back to the
traditional and simpler name.
See commits
5c5a7680e67b ("platform: Provide a remove callback that returns no value")
0edb555a65d1 ("platform: Make platform_driver::remove() return void")
for background to this all"

RCU fix for v6.12
Fix rcuog kthread wakeup invocation from softirq context on a CPU which has been marked offline. This can happen when new callbacks are enqueued from a softirq on an offline CPU before it calls rcutree_report_cpu_dead(). When this happens on NOCB configuration, the rcuog wake-up is deferred through an IPI to an online CPU. This is done to avoid call into the scheduler which can risk arming the RT-bandwidth after hrtimers have been migrated out and disabled. However, doing IPI call from softirq is not allowed Fix this by forcing deferred rcuog wakeup through the NOCB timer when the CPU is offline. -----BEGIN PGP SIGNATURE----- iHUEABYIAB0WIQSi2tPIQIc2VEtjarIAHS7/6Z0wpQUCZwjWYAAKCRAAHS7/6Z0w pQ8iAP9vbhWlWuwlfZqQJK8Xb5b0kVx3nJjAin/5pY/lbWV7IgEA1DUzTAZKXU5Z yZmjM3l9RpMAxLSgevJKoJD+vR0POQA= =EVin -----END PGP SIGNATURE----- Merge tag 'rcu.fixes.6.12-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rcu/linux Pull RCU fix from Neeraj Upadhyay: "Fix rcuog kthread wakeup invocation from softirq context on a CPU which has been marked offline.

Power management updates for 6.12-rc3
- Fix the TPMI_RAPL_REG_DOMAIN_INFO register offset in the TPMI part of
the Intel RAPL power capping driver, make it ignore minor hardware
version mismatches (which only indicate exposing additional features)
and update register definitions in it to enable PL4 support (Zhang
Rui).
- Add Arrow Lake-U to the list of processors supporting PL4 in the MSR
part of the Intel RAPL power capping driver (Sumeet Pawnikar).
- Remove excess pci_disable_device() calls from the processor part of
the int340x thermal driver to address a warning triggered during
module unload and remove unused CPU hotplug code related to RAPL
support from it (Zhang Rui).

This is because is it done very early in the exception and there are not enough registers available to keep a pointer to thread struct. However, dcbz instruction is buggy and doesn't update DAR register on fault. That is detected and generates a call to FixupDAR workaround which updates DAR copy in thread struct but doesn't fix DAR register. Let's fix DAR in addition to the update of DAR copy in thread struct.

ring-buffer: Fix for 6.12
- Do not have boot-mapped buffers use CPU hotplug callbacks When a ring buffer is mapped to memory assigned at boot, it also splits it up evenly between the possible CPUs. But the allocation code still attached a CPU notifier callback to this ring buffer. When a CPU is added, the callback will happen and another per-cpu buffer is created for the ring buffer. But for boot mapped buffers, there is no room to add another one (as they were all created already). The result of calling the CPU hotplug notifier on a boot mapped ring buffer is unpredictable and could lead to a system crash. If the ring buffer is boot mapped simply do not attach the CPU notifier to it. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZwfxchQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qrduAQC2xZ+lqeoDJ3o+H201bqshgx/YDANF p1q1BFmC0yFlOAD/XB/I9o4UFNHAb9D05zPADS+8bF1RxdisJJjqUae1TgM= =lBZ/ -----END PGP SIGNATURE----- Merge tag 'trace-ringbuffer-v6.12-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fix from Steven Rostedt: "Ring-buffer fix: do not have boot-mapped buffers use CPU hotplug callbacks When a ring buffer is mapped to memory assigned at boot, it also splits it up evenly between the possible CPUs.

of: Skip kunit tests when arm64+ACPI doesn't populate root node
A root node is required to apply DT overlays. A root node is usually
present after commit 7b937cc243e5 ("of: Create of_root if no dtb
provided by firmware"), except for on arm64 systems booted with ACPI
tables. In that case, the root node is intentionally not populated
because it would "allow DT devices to be instantiated atop an ACPI base
system"[1].
Introduce an OF function that skips the kunit test if the root node
isn't populated. Limit the test to when both CONFIG_ARM64 and
CONFIG_ACPI are set, because otherwise the lack of a root node is a bug.
Make the function private and take a kunit test parameter so that it
can't be abused to test for the presence of the root node in non-test
code.
Use this function to skip tests that require the root node. Currently
that's the DT tests and any tests that apply overlays.

rcu/nocb: Fix rcuog wake-up from offline softirq
After a CPU has set itself offline and before it eventually calls
rcutree_report_cpu_dead(), there are still opportunities for callbacks
to be enqueued, for example from a softirq. When that happens on NOCB,
the rcuog wake-up is deferred through an IPI to an online CPU in order
not to call into the scheduler and risk arming the RT-bandwidth after
hrtimers have been migrated out and disabled.
But performing a synchronized IPI from a softirq is buggy as reported in
the following scenario:
WARNING: CPU: 1 PID: 26 at kernel/smp.c:633 smp_call_function_single
Modules linked in: rcutorture torture
CPU: 1 UID: 0 PID: 26 Comm: migration/1 Not tainted 6.11.0-rc1-00012-g9139f93209d1 #1
Stopper: multi_cpu_stop+0x0/0x320 <- __stop_cpus+0xd0/0x120
RIP: 0010:smp_call_function_single
<IRQ>
swake_up_one_online
__call_rcu_nocb_wake
__call_rcu_common
? rcu_torture_one_read
call_timer_fn
__run_timers
run_timer_softirq
handle_softirqs
irq_exit_rcu
? tick_handle_periodic
sysvec_apic_timer_interrupt
</IRQ>
Fix this with forcing deferred rcuog wake up through the NOCB timer when
the CPU is offline. The actual wake up will happen from
rcutree_report_cpu_dead().

(????????) ---[ end trace 0000000000000000 ]--- This patch add a toy implementation that performs a simple return to prevent such panic. This is because MSS can be set in sock_create_kern or smc_setsockopt, similar to how it's done in AF_SMC. However, for AF_SMC, there is currently no way to synchronize MSS within __sys_connect_file. This toy implementation lays the groundwork for us to support such feature for IPPROTO_SMC in the future.

docs: netdev: document guidance on cleanup patches
The purpose of this section is to document what is the current practice regarding clean-up patches which address checkpatch warnings and similar problems. I feel there is a value in having this documented so others can easily refer to it. Clearly this topic is subjective. And to some extent the current practice discourages a wider range of patches than is described here. But I feel it is best to start somewhere, with the most well established part of the current practice.

Merge branch 'rtnetlink-handle-error-of-rtnl_register_module'
Kuniyuki Iwashima says:
====================
rtnetlink: Handle error of rtnl_register_module().
While converting phonet to per-netns RTNL, I found a weird comment
/* Further rtnl_register_module() cannot fail */
that was true but no longer true after commit addf9b90de22 ("net:
rtnetlink: use rcu to free rtnl message handlers").
Many callers of rtnl_register_module() just ignore the returned
value but should handle them properly.
This series introduces two helpers, rtnl_register_many() and
rtnl_unregister_many(), to do that easily and fix such callers.
All rtnl_register() and rtnl_register_module() will be converted
to _many() variant and some rtnl_lock() will be saved in _many()
later in net-next.
Changes:
v4:
* Add more context in changelog of each patch
v3: https://lore.kernel.org/all/20241007124459.5727-1-kuniyu@amazon.com/
* Move module *owner to struct rtnl_msg_handler
* Make struct rtnl_msg_handler args/vars const
* Update mctp goto labels
v2: https://lore.kernel.org/netdev/20241004222358.79129-1-kuniyu@amazon.com/
* Remove __exit from mctp_neigh_exit().

phonet: Handle error of rtnl_register_module().
Before commit addf9b90de22 ("net: rtnetlink: use rcu to free rtnl
message handlers"), once the first rtnl_register_module() allocated
rtnl_msg_handlers[PF_PHONET], the following calls never failed.
However, after the commit, rtnl_register_module() could fail silently
to allocate rtnl_msg_handlers[PF_PHONET][msgtype] and requires error
handling for each call.
Handling the error allows users to view a module as an all-or-nothing
thing in terms of the rtnetlink functionality. This prevents syzkaller
from reporting spurious errors from its tests, where OOM often occurs
and module is automatically loaded.
Let's use rtnl_register_many() to handle the errors easily.
Fixes: addf9b90de22 ("net: rtnetlink: use rcu to free rtnl message handlers")
