powerpc/entry: Fix double accounting of user time on interrupt entry
Since the switch to generic entry, an interrupt from user mode accounts user time twice: once in arch_interrupt_enter_prepare() and again in arch_enter_from_user_mode(), which irqentry_enter() invokes for the same interrupt: arch_interrupt_enter_prepare() account_cpu_user_entry() /* first */ irqentry_enter() arch_enter_from_user_mode() account_cpu_user_entry() /* second */ The second call charges the same interval again, because account_cpu_user_entry() accumulates the time spent in user mode since the last return to user space. The two calls come from the GENERIC_ENTRY preparation series, where each step was a no-op on its own. Commit |

The current use of strnlen(text, sizeof(n)) triggers -Wstringop-overread

sizeof(n) before memcpy().

powerpc/entry: Fix irq_soft_mask corruption on replayed interrupt exit
When __replay_soft_interrupts() replays a pending interrupt (e.g.
PACA_IRQ_DEC -> timer_interrupt), it calls the handler directly with a
synthetic pt_regs. The DEFINE_INTERRUPT_HANDLER_ASYNC wrapper around
each handler calls arch_interrupt_async_exit_prepare() on the way out,
which calls arch_interrupt_exit_prepare() -> local_irq_disable() ->
arch_local_irq_disable(), which does:
irq_soft_mask_set(IRQS_DISABLED) /* 0x1 */
This unconditionally overwrites irq_soft_mask with IRQS_DISABLED (0x1),
stripping the IRQS_PMI_DISABLED (0x2) bit. The result is that
irq_soft_mask is 0x1 instead of IRQS_ALL_DISABLED (0x3) when the
handler returns to __replay_soft_interrupts().
For a normally-taken interrupt this is harmless: the next interrupt
always enters through arch_interrupt_enter_prepare() which
unconditionally sets irq_soft_mask to IRQS_ALL_DISABLED. But during
replay, next_interrupt() is called directly between replayed handlers
without going back through arch_interrupt_enter_prepare(), so the
stripped bit is never restored. next_interrupt() then fires a WARNING:
WARNING: arch/powerpc/kernel/irq_64.c:75
WARN_ON(irq_soft_mask_return() != IRQS_ALL_DISABLED)
The warning was observed early in boot on a POWER10 pseries guest
during kmem_cache_init_late(), where a spinlock release triggers
interrupt replay that processes a pending timer interrupt.
Debugger state confirming the bug:
Before timer_interrupt(®s):
irq_soft_mask = 0x3 (IRQS_ALL_DISABLED) correct
irq_happened = 0x41 (HARD_DIS|REPLAYING) correct
After timer_interrupt(®s) returns:
irq_soft_mask = 0x1 (IRQS_DISABLED) WRONG - PMI bit stripped
irq_happened = 0x41 unchanged
The fix is to replace local_irq_disable() with hard_irq_disable().
hard_irq_disable() is the right primitive here for two reasons:
1. On PPC64 (hw_irq.h:301) it calls irq_soft_mask_set_return(IRQS_ALL_DISABLED),
setting the soft mask to 0x3 (both IRQS_DISABLED and IRQS_PMI_DISABLED),
which preserves the PMI bit and fixes the WARNING. The additional
work it does (__hard_irq_disable(), PACA_IRQ_HARD_DIS |=) is
redundant but safe since both are already set at this point in the
exit path; the trace_hardirqs_off() inside is guarded by
if (!arch_irqs_disabled_flags(flags)) so it will not double-fire.
2. On PPC32 (hw_irq.h:467) hard_irq_disable() maps to
arch_local_irq_disable() -> __hard_irq_disable(), which clears
MSR[EE] in hardware. This is exactly correct: PPC32 has no soft-mask
PACA mechanism, so the hardware disable is the right way to satisfy
irqentry_exit()'s requirement. This also fixes a build error on PPC32
where irq_soft_mask_set() is only defined under CONFIG_PPC64:
arch/powerpc/include/asm/entry-common.h:273: error: implicit
declaration of function 'irq_soft_mask_set'
Using hard_irq_disable() requires no #ifdef and is consistent with
how the rest of the entry code (e.g. entry-common.h:463) handles the
same PPC32/PPC64 split.

powerpc/rtas_pci: No hotplug on permanently removed device on pSeries
The eeh_driver disables and offlines the PE permanently when it exceeds the freeze count beyond eeh_max_freeze within the last hour. The PE is only offline, so the device tree entries, eeh device references are all intact till the real unplug of the device from the guest/host takes place. On pSeries, with a new hotplug of any PCI device, the drmgr initiates a system-wide PCI rescan, which finds devices offlined by the eeh_driver and there will be attempts to bring them online. This leads to recurring EEHs either at the config read time itself or a bit later depending on the type of the problem. For PowerNV, the commit |

powerpc: Do not restore KUAP in arch_exit_to_user_mode_prepare()
KUAP means kernel cannot touch user memory unless it explicitly is enabled. In the kernel it should stay AMR_KUAP_BLOCKED. While returning to userspace just before RFI, kernel should restore the user AMR value back. Looks like GENERIC_ENTRY might be treating arch_exit_to_user_mode_prepare() as the last architecture step before returning to userspace. commit |

powerpc: Don't drop _TIF_RESTOREALL on syscall restart
So the syscall return sequence is as follows:
A syscall return to userspace is prepared and then a short asm sequence
that actually does the RFI. Note that this asm range is restartable i.e.
EE is still on, so an interrupt (e.g. decrementer or external interrupt)
can hit while SRR/GPRs are being loaded. This is defined via:
RESTART_TABLE(.Lsyscall_rst_start, .Lsyscall_rst_end, syscall_restart)
This restart table then sends us to syscall_restart rather than resuming
in the middle of the RFI. The same stub is also used if irq_happened
already has a pending bit (soft-masked irq that has not been replayed
yet (PowerPC special case of local_irq_disable())).
Here is a bit of a flow of sequence of code to visualize:
syscall_exit_prepare
decide full-GPR restore (_TIF_RESTOREALL) for signal,
rt_sigreturn or syscall trace
save that in regs->exit_result and return it in r3
|
v
.Lsyscall_rst_start .. _end EE still on
irq_happened set or interrupt in this range?
| no | yes
v v
cmpdi r3,0 syscall_exit_restart
restore all / zero replay irq, try exit again
volatiles; RFI must return flags in r3
again for the same cmpdi
Now r3 after prepare is the flags word, not the actual syscall return. A nested
interrupt clobbers it, so the restart stub reloads RESULT into r3 and the
C handler (syscall_exit_restart()) should put the flags back (because later asm
checks whether r3 returned from C has _TIF_RESTOREALL set or not):
cmpdi r3, 0
bne .Lsyscall_restore_regs
Note that syscall_exit_restart() already ORs any new _TIF_RESTOREALL into
exit_result, but then it only returns the new sample and not the full
regs->exit_result.
That sample could be often 0 even when restore-all is still required:
- rt_sigreturn / syscall trace set the bit in prepare's local
ret and in exit_result. They never set exit_flags, which is
what restart samples.
- a signal does set exit_flags but restart clears it. A
second pass through the stub then returns 0 while
exit_result still has the bit.
The asm as mentioned earlier then treats r3==0 as the fast path and
zeros r0/r4-r12. That means the userspace that needed the full register
set could SIGSEGVs, (which could happen often in ld64.so.2 like while
doing a parallel kernel build as reported by Venkat).
So we should instead return the accumulated exit_result, like how we do
in interrupt_exit_user_restart(). Note that prior to this commit

powerpc/entry: Clear TIF_SYSCALL_RET before syscall error return
Shivaprasad reported a boot failure due to userspace processes crash on
abort() from libc.so.6. It was bisected to merge request
commit '3424d8c18a7d ("Merge tag 'core-entry-2026-08-17' of
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip")'
Upon checking the merge, when syscall_enter_from_user_mode_randomize_stack
fails, which could happen when a tracer like seccomp or ptrace intercepts
and skips the syscall, the code returns to userspace immediately without
clearing the intermediate flag which was set.
When the next syscall is made, it immediately aborts the valid syscall
since the flag is still set. Hence clear the flag on occurrence of first
failure.

Rust fixes for v7.3
Toolchain and infrastructure:
- Fix KCFI failures, such as in Rust doctests, by disabling function
merging when CFI is enabled. Gary reported the LLVM bug to upstream
and it is now fixed in their mainline.
- Fix 'objtool' fallthrough warnings under the experimental
'CONFIG_RUST_INLINE_HELPERS' by passing (for the combined Rust and
helpers code) the LLVM options needed to preserve the unreachable
traps that 'rustc' normally emits.
In addition, fix 'objtool' errors when LTO is enabled on top, by
also filtering out the LTO flags (for the combined Rust and helpers
code) so that the traps are kept in place.
- Fix 'objtool' warnings by adding one more 'noreturn' function.
- Fix 'make rusttest' target when the 'rustc-dev' component is
installed and Rust >= 1.82.0, <= 1.87.0 is used.
'kernel' crate:
- 'num' module: fix soundness issue in the 'Bounded' conversion from
'bool' by restricting the conversions to unsigned 'Bounded'.
- 'jump_label' module: fix future 'make rusttest' target failures when
'ARCH=' is set to an arch different than the host's.
- 'list' module: fix incorrect 'pop_back()' comment.

Pull Rust fixes from Miguel Ojeda:
"Toolchain and infrastructure:
- Fix KCFI failures, such as in Rust doctests, by disabling function
merging when CFI is enabled. Gary reported the LLVM bug to upstream
and it is now fixed in their mainline.
- Fix 'objtool' fallthrough warnings under the experimental
'CONFIG_RUST_INLINE_HELPERS' by passing (for the combined Rust and
helpers code) the LLVM options needed to preserve the unreachable
traps that 'rustc' normally emits.
In addition, fix 'objtool' errors when LTO is enabled on top, by
also filtering out the LTO flags (for the combined Rust and helpers
code) so that the traps are kept in place.
- Fix 'objtool' warnings by adding one more 'noreturn' function.
- Fix 'make rusttest' target when the 'rustc-dev' component is
installed and Rust >= 1.82.0, <= 1.87.0 is used.
'kernel' crate:
- 'num' module: fix soundness issue in the 'Bounded' conversion from
'bool' by restricting the conversions to unsigned 'Bounded'.
- 'jump_label' module: fix future 'make rusttest' target failures
when 'ARCH=' is set to an arch different than the host's.
- 'list' module: fix incorrect 'pop_back()' comment"

tracing fixes for v7.3:
- Fix error output of boot instance creation failure Currently if a boot instance creation fails, instead of printing out the name of the instance that failed, it prints "(null)". That is because it prints "cur_str" that had already been processed by strsep(). Print the saved name instead. While at it, print the error code of the failure. - Fix use-after-free for same named historgrams Histograms can be named so that they can be used in multiple events. But if the named histogram has a variable attached, the second event that uses the named histogram which duplicates it and needs to free the original after duplication leaves the old variable in place and still visible. If another histogram uses than variable, it will use the stale one which will try to reference the freed duplicate histogram and crash the kernel. Free the duplicate variables along with the duplicated histogram data. - Check return value of kthread_run() in event self test The events self tests uses a kthread for testing but does not check if it succeeded in creating a kthread. If the kthread creation were to fail, the code will still try to call kthread_stop() on the error returned. - Fix race between reading trace_pipe and updating subbuffer size If a user is reading the trace_pipe file at the same time they update the ring buffer sub-buffer size, can cause the trace_pipe read to read stale data. Add trace_access_lock() around updating the ring buffer sub-buffer size. - Fix eventfs_inode on failure path in creation of the events directory In the creation of the "events" directory, if after allocating the eventfs_inode a failure is detected, it calls cleanup_ei() which calls free_ei(). The free_ei() will test if eventfs_inode being freed has no children. It is a bug if it does. But on the failure case of the creation of the "events" directory, the children lists have not yet been initialized and the free will trigger a warning because list_empty() on an uninitialized list returns false. Move the initialization into init_ei() where it makes more sense and makes sure that a created eventfs_inode has its lists initialized upon creation. - Check return value of kthread_run() in ftrace direct sample code The sample code that shows how to use the ftrace direct calls does not test the return of kthread_run() to see if it succeeds. Return a failure if the kthread_run() doesn't succeed. - Clear user events state on fork in case of alloc failure On fork, the child gets a pointer to the parent's user events state. It makes a copy of it then updates the child's pointer to it. But if the allocation fails, the duplication function leaves the child with a pointer to its parent's descriptor. When the child cleans up its data, it will free the parent's descriptor while the parent is still using it. In the duplication function, set the child's user_event_mm to NULL before testing if the allocation succeeded, and when it exits it will not free the parent's descriptor. - Fix retry exhaustion in simple ring buffer reader swap simple_ring_buffer_swap_reader_page() starts with retry set to 8 and post-decrements it only after a failed link replacement. On the final attempt, a successful replacement leaves retry at zero, while a failed replacement leaves it at -1. But the check for success expects the retry value to be non-zero and exits with an error on zero. This is the opposite result. Fix it. - Fail nicely when the remote swap_reader_page() returns an error Currently, if the swap_reader_page() of a remote buffer fails, it triggers a WARN_ON_ONCE() and continues normally. Instead, have it exit with an error and a pr_warn() print instead of a full WARNING. -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCapOC3hQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qvjkAQCGVuyK980rwiBnfenWLpeB3QjfHA8B mV0mJSlGWm1t1gEA9WWzMGbp+OHeRV2xyA+xW7OS1S58VO9OIGrzXCGqbAM= =TrF5 -----END PGP SIGNATURE----- Merge tag 'trace-v7.3-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Fix error output of boot instance creation failure Currently if a boot instance creation fails, instead of printing out the name of the instance that failed, it prints "(null)".

openrisc: fix arbitrary kernel memory access via or1k_atomic syscall
sys_or1k_atomic() (syscall 244 in the "or1k" ABI) takes two user
pointers, v1 and v2, and swaps the words they point to in hand-written
assembly.
l.lwz r29,0(r4)
l.lwz r27,0(r5)
l.sw 0(r4),r27
l.sw 0(r5),r29
The pointers are not checked with access_ok(). The four memory
accesses also have no exception table entries.
A caller passes a kernel address as either pointer, and the syscall
reads from and writes to it directly.
This gives an unprivileged process a kernel read/write primitive. It
overwrites kernel data such as the sys_call_table, gaining code
execution in kernel context.
Check both pointers before entering the critical section. Add fixups
for the four memory accesses so faults on valid but unmapped user
addresses return -EFAULT.

ipmi: Fix some minor issues, add async init
Several cleanup on error fixes and a missing RCU wait and proper validation on a received message in one place. The biggest change is the initialization of the driver can be done asynchronously on a work queue.

A wide variety of mostly CephFS fixes and cleanups, split between
changes that address edge cases (Sam, Xiubo, Matthew), efficiency improvements (Max) and AI-assisted hardening (Michael, Jeremy). One thing that stands out is Alex's change to how CephFS behaves in NEARFULL scenarios: the long-standing "make all writes synchronous" behavior has become opt-in. It was always somewhat controversial and doesn't make much sense for modern deployments; the new default is to continue normal operation (i.e. buffer writes as MDS allows, etc). The behavior in case the cluster reaches any FULL state remains the same as before. -----BEGIN PGP SIGNATURE----- iQFHBAABCgAxFiEEydHwtzie9C7TfviiSn/eOAIR84sFAmqRz9QTHGlkcnlvbW92 QGdtYWlsLmNvbQAKCRBKf944AhHzi/63CACpEmwY/3lOZ4M0IQV2UJqSWzNNtUDI Hdq7hosk5gRXP/gG1bV63i935Ibe/Sp6Cb/XkTRcrPIxy/1eky8PDZN3knPlPocM TMAdLKUOzzpmehqORWdVsEGSYIXuIfVhrey30pfHVLQc86orTj7worDZydYl8r3L K6nAM8gfcT9l9Sd4jtquaT61kqCcjXKPANlvUtt8oqniMRdpL63GnFHaU33n3XTE 5Dalh4YHtIL4gTA6xZLbZqOq+99QbmmqlqlMiwFNtrfpVtPO7HWHrEy61mYrKW7U Nr7HRF6X+MeUngZVI5AgrH5K6HtlE0SeHZt2XSKuMKGMG+I4dcygUcSr =F8+z -----END PGP SIGNATURE----- Merge tag 'ceph-for-7.3-rc1' of https://github.com/ceph/ceph-client Pull ceph updates from Ilya Dryomov: "A wide variety of mostly CephFS fixes and cleanups, split between changes that address edge cases (Sam, Xiubo, Matthew), efficiency improvements (Max) and AI-assisted hardening (Michael, Jeremy).

f2fs-for-7.3-rc1
In this round, key enhancements focus on reducing inode management memory
overhead, introducing resizable tail sections with unified pinned allocation,
and boosting I/O throughput via parallel multi-device flushes and asynchronous
f2fs_write_end_io() execution. We also add dynamic device alias reservations to
allow on-the-fly space donation from user partitions.
Alongside these features, critical bug fixes resolve folio race conditions,
lingering dirty flags, dentry and block counter leaks, and potential deadloops
in f2fs_fsync_node_pages(). Additional stability patches address error-path
handling across symlink, sync, and rename/unlink operations, prevent pinned file
fragmentation, and correct segment migration and free section accounting in
free_segment_range.
Enhancement:
- reduce memory footprint of ino management
- support dynamic reserve/release for device aliasing
- issue multi-device flushes in parallel
- add a way to run f2fs_write_end_io() asynchronously
- support resizable tail section and unify pinned allocation
Bug fix:
- fix to pass folio->index to f2fs_sanity_check_node_footer()
- fix folio_nr_pages() race after put in large folio invalidate
- fix to clear dirty flag on folio in error path
- accurately adjust free_sections during free_segment_range
- fix to avoid potential deadloop in f2fs_fsync_node_pages()
- fix the error path in symlink, device alias in rename/unlink,
f2fs_sync_fs,
- fix to migrate all curseg types during free_segment_range
- fix to avoid pinfile fragment on fragment:{block, segment} mode
- fix valid block count leak on data block allocation failure
- fix dentry folio leak in find_in_level
- reject overlapping move range after len expansion
- fix some bugs related to file pinning, GC functions, i_size.
And, the series includes a number of minor bug fixes.

Hi,
I had to think a lot how to put this into few paragraphs. I hope this will makes sense to you and I'm not too confusing. The bulk of this pull request are Ross Philipson's TPM enablers for the Trenchboot patch series. The commits expose TPM constants, and decouple and improve robustness of tpm_buf a bit in order to implement a minimal early TPM driver. Early boot code will call either SKINIT on AMD or GETSEC[SENTER] on Intel before jumping into kernel's entry point. They re-initalize TPM PCRs but leave up to the early boot code measure initrd, boot_params and Trenchboot associated metadata. The motivation here is just that we would want in future iterations of the series put our full focus to the x86 part of the review, and call it a day as per TPM changes. Further, even if Trenchboot turned out to be empty lottery the worst possible outcome for TPM driver is that things get cleaned up a bit.

ring-buffer: Stop remote reader update when page swap fails
The remote swap_reader_page callback can return -EBUSY when the writer
moves the head before the remote catches it, particularly during an event
storm on a small buffer. __rb_get_reader_page_from_remote() currently
warns about that failure but continues with the unchanged reader ID and
rearranges the local page list as though the swap succeeded.
Handle the callback failure as a recoverable error. Report it with
pr_warn_ratelimited() and return NULL. Callers already handle a NULL reader
page as a failed attempt. This avoids splicing the same page as both the
previous and new reader without flooding the log under contention.
