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 --- include/asm-generic/ioctl.h | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) create mode 100644 include/asm-generic/ioctl.h (limited to 'include/asm-generic/ioctl.h') diff --git a/include/asm-generic/ioctl.h b/include/asm-generic/ioctl.h new file mode 100644 index 000000000..9fda9ed00 --- /dev/null +++ b/include/asm-generic/ioctl.h @@ -0,0 +1,18 @@ +/* SPDX-License-Identifier: GPL-2.0 */ +#ifndef _ASM_GENERIC_IOCTL_H +#define _ASM_GENERIC_IOCTL_H + +#include + +#ifdef __CHECKER__ +#define _IOC_TYPECHECK(t) (sizeof(t)) +#else +/* provoke compile error for invalid uses of size argument */ +extern unsigned int __invalid_size_argument_for_IOC; +#define _IOC_TYPECHECK(t) \ + ((sizeof(t) == sizeof(t[1]) && \ + sizeof(t) < (1 << _IOC_SIZEBITS)) ? \ + sizeof(t) : __invalid_size_argument_for_IOC) +#endif + +#endif /* _ASM_GENERIC_IOCTL_H */ -- cgit v1.3.1
