(v1 was created mistakenly. Please igore it.) lib/audit.c provides a generic definition for auditing system calls. lib/compat_audit.c similarly adds compat syscall support for bi-architectures (32/64-bit). Each architecture must define audit_is_compat() in asm/audit.h.

Will, I always thank you for your comments: On 11/26/2013 04:01 AM, Will Deacon wrote: You are completely right. In my current (v3 prototype) implementation, "abi" argument, which can be AUDIT_ARCH_ARM(EB) or AUDIT_ARCH_AARCH64(EB), passed to audit_classify_syscall() is determined per-task using is_compat_thread() when audit_syscall_entry() is executed in syscall_trace(). (Obviously audit_is_compat() is true only in case of AUDIT_ARCH_ARM.) V3 based on this patch is working for 32-bit and 64-bit userland. I can submit v3 patch if you want. Thanks, -Takahiro AKASHI

You could use a CONFIG_AUDIT_COMPAT_GENERIC and simplify other #ifdefs as well. Here and in other places, just define a default audit_is_compat() functions which returns false when !CONFIG_COMPAT to avoid the #ifdefs. It most likely is architecture dependent. BTW, since they aren't many, you could get the arch code to define __NR_compat_open etc. explicitly and use these. On arm64 we have a few of these defined to avoid name collision in signal handling code. -- Catalin

My preference is as above, a few __NR_compat_* (just those required by audit) defined in unistd.h but I'm not an audit maintainer. -- Catalin

To: Eric, Al Could you please give me your comments on my patch below? I don't think this patch breaks anything on existing architectures which support audit. If you don't prefer the way, I'm going to keep the code arm64-specific to support audit on AArch64(arm64) as in my old patch series.: https://www.redhat.com/archives/linux-audit/2013-November/msg00040.html Thank you, -Takahiro AKASHI On 11/19/2013 04:33 PM, AKASHI Takahiro wrote:
