[PATCH] arm64: Add MIDR-based check for FEAT_ECBHB

by Oliver Upton

Prior to commit e8cde32f111f ("arm64/cpufeatures/kvm: Add ARMv8.9 FEAT_ECBHB bits in ID_AA64MMFR1 register") KVM was erroneously masking FEAT_ECBHB from VMs, giving the perception that safe implementations are actually vulnerable to Spectre-BHB. And, after commit e403e8538359 ("arm64: errata: Assume that unknown CPUs _are_ vulnerable to Spectre BHB") guests are enabling the loop mitigation. This broken virtual hardware is going to be around for some time, so do the ugly thing and check for revisions of Neoverse-V2 [1], Cortex-X3 [2], Cortex-A720 [3], and Neoverse-N3 [4] that are documented to have FEAT_ECBHB.

[PATCH v3 0/3] pwm: axi-pwmgen: add external clock

by David Lechner

When we created the driver for the AXI PWMGEN IP block, we overlooked the fact that it can optionally be configured to use an external clock in addition to the AXI bus clock. This is easy to miss in testing because the bus clock is always on because it is driving other peripherals as well. Up to now, users were specifying the external clock if there was one and the AXI bus clock otherwise. But the proper way to do this is to would be to always specify the bus clock and only specify the external clock if the IP block has been configured to use it. To fix this, we add clock-names to the devicetree bindings and change clocks to allow 1 or 2 clocks. --- Changes in v3: - Fixed clock-names DT property restrictions (was failing dt_binding_check) - Added Cc: stable - Picked up trailers - Link to v2: https://lore.kernel.org/r/20250522-pwm-axi-pwmgen-add-external-clock-v2-0-0… Changes in v2: - Consider this a fix rather than a new feature. - Make clock-names required. - Simplify the logic in the pwm driver to avoid needing to test if clock-names is present in old dtbs that used the broken binding. - Link to v1: https://lore.kernel.org/r/20250520-pwm-axi-pwmgen-add-external-clock-v1-0-6… --- David Lechner (3): dt-bindings: pwm: adi,axi-pwmgen: update documentation link dt-bindings: pwm: adi,axi-pwmgen: fix clocks pwm: axi-pwmgen: fix missing separate external clock .../devicetree/bindings/pwm/adi,axi-pwmgen.yaml | 15 +++++++++++--- drivers/pwm/pwm-axi-pwmgen.c | 23 +++++++++++++++++++--- 2 files changed, 32 insertions(+), 6 deletions(-) --- base-commit: 484803582c77061b470ac64a634f25f89715be3f change-id: 20250515-pwm-axi-pwmgen-add-external-clock-0364fbdf809b Best regards, -- David Lechner <dlechner(a)baylibre.com>

[PATCH] iio: accel: fxls8962af: Fix use after free in fxls8962af_fifo_flush

by Sean Nyekjaer

fxls8962af_fifo_flush() uses indio_dev->active_scan_mask (with iio_for_each_active_channel()) without making sure the indio_dev stays in buffer mode. There is a race if indio_dev exits buffer mode in the middle of the interrupt that flushes the fifo.

[PATCH] mm: Fix vmstat after removing NR_BOUNCE

by Kirill A. Shutemov

Hongyu noticed that the nr_unaccepted counter kept growing even in the absence of unaccepted memory on the machine. This happens due to a commit that removed NR_BOUNCE: it removed the counter from the enum zone_stat_item, but left it in the vmstat_text array. As a result, all counters below nr_bounce in /proc/vmstat are shifted by one line, causing the numa_hit counter to be labeled as nr_unaccepted. To fix this issue, remove nr_bounce from the vmstat_text array. Signed-off-by: Kirill A.

This clashes with the protection bit define from the uapi for mmap() declared in include/uapi/asm-generic/mman-common.h, which is indeed what those casually reading this code would assume this to refer to.

[PATCH v2] iio: adc: adi-axi-adc: fix ad7606_bus_reg_read()

by David Lechner

Mask the value read before returning it. The value read over the parallel bus via the AXI ADC IP block contains both the address and the data, but callers expect val to only contain the data. axi_adc_raw_write() takes a u32 parameter, so addr was the wrong type. This wasn't causing any issues but is corrected anyway since we are touching the same line to add a new variable.

[PATCH 1/2] apparmor: Fix 8-byte alignment for initial dfa blob streams

by deller＠kernel.org

From: Helge Deller <deller(a)gmx.de> The dfa blob stream for the aa_dfa_unpack() function is expected to be aligned on a 8 byte boundary. The static nulldfa_src[] and stacksplitdfa_src[] arrays store the inital apparmor dfa blob streams, but since they are declared as an array-of-chars the compiler and linker will only ensure a "char" (1-byte) alignment. Add an __aligned(8) annotation to the arrays to tell the linker to always align them on a 8-byte boundary. This avoids runtime warnings at startup on alignment-sensitive platforms like parisc such as: Kernel: unaligned access to 0x7f2a584a in aa_dfa_unpack+0x124/0x788 (iir 0xca0109f) Kernel: unaligned access to 0x7f2a584e in aa_dfa_unpack+0x210/0x788 (iir 0xca8109c) Kernel: unaligned access to 0x7f2a586a in aa_dfa_unpack+0x278/0x788 (iir 0xcb01090) Signed-off-by: Helge Deller <deller(a)gmx.de> Cc: stable(a)vger.kernel.org --- security/apparmor/lsm.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/security/apparmor/lsm.c b/security/apparmor/lsm.c index 9b6c2f157f83..531bde29cccb 100644 --- a/security/apparmor/lsm.c +++ b/security/apparmor/lsm.c @@ -2149,12 +2149,12 @@ static int __init apparmor_nf_ip_init(void) __initcall(apparmor_nf_ip_init); #endif -static char nulldfa_src[] = { +static char nulldfa_src[] __aligned(8) = { #include "nulldfa.in" }; static struct aa_dfa *nulldfa; -static char stacksplitdfa_src[] = { +static char stacksplitdfa_src[] __aligned(8) = { #include "stacksplitdfa.in" }; struct aa_dfa *stacksplitdfa; -- 2.47.0
