2025-09-16x86/bugs: Fix reporting of LFENCE retpolineDavid Kaplan
The LFENCE retpoline mitigation is not secure but the kernel prints inconsistent messages about this fact. The dmesg log says 'Mitigation: LFENCE', implying the system is mitigated. But sysfs reports 'Vulnerable: LFENCE' implying the system (correctly) is not mitigated. Fix this by printing a consistent 'Vulnerable: LFENCE' string everywhere when this mitigation is selected.

2025-09-16x86/bugs: Fix spectre_v2 forcingDavid Kaplan
There were two oddities with spectre_v2 command line options. First, any option other than 'off' or 'auto' would force spectre_v2 mitigations even if the CPU (hypothetically) wasn't vulnerable to spectre_v2. That was inconsistent with all the other bugs where mitigations are ignored unless an explicit 'force' option is specified. Second, even though spectre_v2 mitigations would be enabled in these cases, the X86_BUG_SPECTRE_V2 bit wasn't set. This is again inconsistent with the forcing behavior of other bugs and arguably incorrect as it doesn't make sense to enable a mitigation if the X86_BUG bit isn't set. Fix both issues by only forcing spectre_v2 mitigations when the 'spectre_v2=on' option is specified (which was already called SPECTRE_V2_CMD_FORCE) and setting the relevant X86_BUG_* bits in that case. This also allows for simplifying bhi_update_mitigation() because spectre_v2_cmd will now always be SPECTRE_V2_CMD_NONE if the CPU is immune to spectre_v2.

2025-09-16powerpc/32: Remove PAGE_KERNEL_TEXT to fix startup failureChristophe Leroy
PAGE_KERNEL_TEXT is an old macro that is used to tell kernel whether kernel text has to be mapped read-only or read-write based on build time options. But nowadays, with functionnalities like jump_labels, static links, etc ... more only less all kernels need to be read-write at some point, and some combinations of configs failed to work due to innacurate setting of PAGE_KERNEL_TEXT. On the other hand, today we have CONFIG_STRICT_KERNEL_RWX which implements a more controlled access to kernel modifications. Instead of trying to keep PAGE_KERNEL_TEXT accurate with all possible options that may imply kernel text modification, always set kernel text read-write at startup and rely on CONFIG_STRICT_KERNEL_RWX to provide accurate protection. Do this by passing PAGE_KERNEL_X to map_kernel_page() in __maping_ram_chunk() instead of passing PAGE_KERNEL_TEXT. Once this is done, the only remaining user of PAGE_KERNEL_TEXT is mmu_mark_initmem_nx() which uses it in a call to setibat(). As setibat() ignores the RW/RO, we can seamlessly replace PAGE_KERNEL_TEXT by PAGE_KERNEL_X here as well and get rid of PAGE_KERNEL_TEXT completely.

2025-09-16powerpc/fprobe: fix updated fprobe for function-graph tracerHari Bathini
Since commit 4346ba160409 ("fprobe: Rewrite fprobe on function-graph tracer"), FPROBE depends on HAVE_FUNCTION_GRAPH_FREGS. With previous patch adding HAVE_FUNCTION_GRAPH_FREGS for powerpc, FPROBE can be enabled on powerpc. But with the commit b5fa903b7f7c ("fprobe: Add fprobe_header encoding feature"), asm/fprobe.h header is needed to define arch dependent encode/decode macros. The fprobe header MSB pattern on powerpc is not 0xf. So, define FPROBE_HEADER_MSB_PATTERN expected on powerpc. Also, commit 762abbc0d09f ("fprobe: Use ftrace_regs in fprobe exit handler") introduced HAVE_FTRACE_REGS_HAVING_PT_REGS for archs that have pt_regs in ftrace_regs. Advertise that on powerpc to reuse common definitions like ftrace_partial_regs().

2025-09-16powerpc/ftrace: support CONFIG_FUNCTION_GRAPH_RETVALAditya Bodkhe
commit a1be9ccc57f0 ("function_graph: Support recording and printing the return value of function") introduced support for function graph return value tracing. Additionally, commit a3ed4157b7d8 ("fgraph: Replace fgraph_ret_regs with ftrace_regs") further refactored and optimized the implementation, making `struct fgraph_ret_regs` unnecessary. This patch enables the above modifications for powerpc all, ensuring that function graph return value tracing is available on this architecture. In this patch we have redefined two functions: - 'ftrace_regs_get_return_value()' - the existing implementation on ppc returns -ve of return value based on some conditions not relevant to our patch. - 'ftrace_regs_get_frame_pointer()' - always returns 0 in current code . We also allocate stack space to equivalent of 'SWITCH_FRAME_SIZE', allowing us to directly use predefined offsets like 'GPR3' and 'GPR4' this keeps code clean and consistent with already defined offsets . After this patch, v6.14+ kernel can also be built with FPROBE on powerpc but there are a few other build and runtime dependencies for FPROBE to work properly. The next patch addresses them.

2025-09-16xfs: fix log CRC mismatches between i386 and other architecturesChristoph Hellwig
When mounting file systems with a log that was dirtied on i386 on other architectures or vice versa, log recovery is unhappy: [ 11.068052] XFS (vdb): Torn write (CRC failure) detected at log block 0x2. Truncating head block from 0xc. This is because the CRCs generated by i386 and other architectures always diff. The reason for that is that sizeof(struct xlog_rec_header) returns different values for i386 vs the rest (324 vs 328), because the struct is not sizeof(uint64_t) aligned, and i386 has odd struct size alignment rules. This issue goes back to commit 13cdc853c519 ("Add log versioning, and new super block field for the log stripe") in the xfs-import tree, which adds log v2 support and the h_size field that causes the unaligned size. At that time it only mattered for the crude debug only log header checksum, but with commit 0e446be44806 ("xfs: add CRC checks to the log") it became a real issue for v5 file system, because now there is a proper CRC, and regular builds actually expect it match. Fix this by allowing checksums with and without the padding.

2025-09-16ALSA: pcm: Disable bottom softirqs as part of spin_lock_irq() on PREEMPT_RTSebastian Andrzej Siewior
snd_pcm_group_lock_irq() acquires a spinlock_t and disables interrupts via spin_lock_irq(). This also implicitly disables the handling of softirqs such as TIMER_SOFTIRQ. On PREEMPT_RT softirqs are preemptible and spin_lock_irq() does not disable them. That means a timer can be invoked during spin_lock_irq() on the same CPU. Due to synchronisations reasons local_bh_disable() has a per-CPU lock named softirq_ctrl.lock which synchronizes individual softirq against each other. syz-bot managed to trigger a lockdep report where softirq_ctrl.lock is acquired in hrtimer_cancel() in addition to hrtimer_run_softirq(). This is a possible deadlock. The softirq_ctrl.lock can not be made part of spin_lock_irq() as this would lead to too much synchronisation against individual threads on the system. To avoid the possible deadlock, softirqs must be manually disabled before the lock is acquired. Disable softirqs before the lock is acquired on PREEMPT_RT.

2025-09-16hinic3: Fix missing napi->dev in netif_queue_set_napiFan Gong
As netif_queue_set_napi checks napi->dev, if it doesn't have it and it will warn_on and return. So we should use netif_napi_add before netif_queue_set_napi because netif_napi_add has "napi->dev = dev".
