ptrace, treewide: Rename ptrace_report_syscall_entry() to ptrace_report_syscall_permit_entry()

2026-07-12T10:38:02+00:00

The return value of that function is boolean and tells the caller whether to permit the syscall processing or not. Rename the function so the purpose is clear and make the return type bool.

seccomp, treewide: Rename and convert __secure_computing() to return boolean

2026-07-12T10:38:02+00:00

The return value of __secure_computing() currently uses 0 to indicate that a system call should be allowed, and -1 to indicate that it should be blocked/killed. This 0/-1 pattern is non-intuitive for a security check function and makes the control flow at the call sites less readable. Furthermore, any potential future changes to these return values would require a high-risk, error-prone audit of all its users across different architectures. Sanitize this logic by converting the return type of __secure_computing() to a proper boolean, where 'true' explicitly means 'allow' and 'false' means 'fail/deny'. Update all the two dozen or so call sites across the tree to align with this new boolean semantic. No functional changes are intended, as the callers still return -1 to the lower-level assembly entry code upon seccomp denial. Rename the function to __seccomp_permit_syscall() so that the purpose is entirely clear.

xtensa/simdisk: Avoid referring to module::args

2026-07-10T12:26:46+00:00

When simdisk support is built as a loadable module, simdisk_param_set_filename() receives a pointer into module::args and stores each filename pointer as is. In preparation for removing module::args, update the simdisk.filename parameter code to copy the provided string. This is somewhat complicated by the fact that simdisk support can also be built-in, in which case the parameters are parsed during early boot before slab is available. In that case, the command line itself is preserved for the lifetime of the kernel, so continue storing the incoming pointer directly. Reviewed-by: Max Filippov Signed-off-by: Petr Pavlu

strncpy() has no remaining callers in the kernel[1]. Remove the xtensa-specific inline assembly implementation and __HAVE_ARCH_STRNCPY define, falling back to the generic version in lib/string.c. Link: https://github.com/KSPP/linux/issues/90 [1] Signed-off-by: Kees Cook

xtensa: correct CONFIG_XTENSA_CALIBRATE_CCOUNT macro name in comment

A comment in arch/xtensa/include/asm/platform.h incorrectly refers to CONFIG_XTENSA_CALIBRATE instead of CONFIG_XTENSA_CALIBRATE_CCOUNT. Correct it. Discovered while searching for CONFIG_* symbols referenced in code but not defined in any Kconfig file.

Pull interrupt core updates from Thomas Gleixner: - Rework of /proc/interrupt handling: /proc/interrupts was subject to micro optimizations for a long time, but most of the low hanging fruit was left on the table. This rework addresses the major time consuming issues: - Printing a long series of zeros one by one via a format string instead of counting subsequent zeros and emitting a string constant. - Simplify and cache the conditions whether interrupts should be printed - Use a proper iteration over the interrupt descriptor xarray instead of walking and testing one by one. - Provide helper functions for the architecture code to emit the architecture specific counters - Convert the counter structure in x86 to an array, which simplifies the output and add mechanisms to suppress unused architecture interrupts, which just occupy space for nothing. Adopt the new core mechanisms. This adjusts the gdb scripts related to interrupt counter statistics to work with the new mechanisms. - Prevent a string overflow in the /proc/irq/$N/ directory name creation code. * tag 'irq-core-2026-06-13' of gitolite.kernel.org:pub/scm/linux/kernel/git/tip/tip: x86/irq: Add missing 's' back to thermal event printout genirq/proc: Speed up /proc/interrupts iteration genirq/proc: Runtime size the chip name genirq: Expose irq_find_desc_at_or_after() in core code genirq: Add rcuref count to struct irq_desc genirq/proc: Increase default interrupt number precision to four genirq: Calculate precision only when required genirq: Cache the condition for /proc/interrupts exposure genirq/manage: Make NMI cleanup RT safe genirq: Expose nr_irqs in core code scripts/gdb: Update x86 interrupts to the array based storage x86/irq: Move IOAPIC misrouted and PIC/APIC error counts into irq_stats x86/irq: Suppress unlikely interrupt stats by default x86/irq: Make irqstats array based genirq/proc: Utilize irq_desc::tot_count to avoid evaluation genirq/proc: Avoid formatting zero counts in /proc/interrupts x86/irq: Optimize interrupts decimals printing genirq/proc: Size interrupt directory names for 10-digit interrupt numbers
