From 75467f60a3d14f08f86f2b353298d2826382ff23 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Fri, 25 Sep 2026 15:55:03 -0700 Subject: Merge tag 'ipe-pr-20260925' of git://git.kernel.org/pub/scm/linux/kernel/git/wufan/ipe Pull IPE fixes from Fan Wu: "Two fixes for use-after-free issues found by recent LLM-assisted code analysis. - move successful policy load auditing under the new policy directory's inode lock, preventing a concurrent policy deletion from freeing the policy while it is still being audited - protect the dm-verity root hash with RCU, preventing policy evaluation from racing with root hash replacement during preresume" * tag 'ipe-pr-20260925' of git://git.kernel.org/pub/scm/linux/kernel/git/wufan/ipe: ipe: protect the dm-verity root hash with RCU ipe: fix use-after-free when auditing a newly loaded policy --- Documentation/ABI/testing/sysfs-kernel-irq | 60 ++++++++++++++++++++++++++++++ 1 file changed, 60 insertions(+) create mode 100644 Documentation/ABI/testing/sysfs-kernel-irq (limited to 'Documentation/ABI/testing/sysfs-kernel-irq') diff --git a/Documentation/ABI/testing/sysfs-kernel-irq b/Documentation/ABI/testing/sysfs-kernel-irq new file mode 100644 index 000000000..8910d0c4b --- /dev/null +++ b/Documentation/ABI/testing/sysfs-kernel-irq @@ -0,0 +1,60 @@ +What: /sys/kernel/irq +Date: September 2016 +KernelVersion: 4.9 +Contact: Craig Gallek +Description: Directory containing information about the system's IRQs. + Specifically, data from the associated struct irq_desc. + The information here is similar to that in /proc/interrupts + but in a more machine-friendly format.
