Subject: [PATCH v2 0/6] arm64: Add audit support
Date: Fri, 17 Jan 2014 17:13:13 +0900 [thread overview]
Message-ID: <1389946399-4525-1-git-send-email-takahiro.akashi@linaro.org> (raw)
In-Reply-To: <1383733546-2846-1-git-send-email-takahiro.akashi@linaro.org>
This patchset adds system call audit support on arm64.
Both 32-bit (AUIDT_ARCH_ARM[EB]) and 64-bit tasks (AUDIT_ARCH_AARCH64[EB])
are supported, but presuming 32-LE on 64-LE or 32-BE on 64-BE.
There are some prerequisites for this patch to work correctly:
* "generic compat system call audit support" patch
* "correct a type mismatch in audit_syscall_exit()" patch
(already accepted and queued in 3.14)
* "Modify a set of system calls in audit class" patch
* userspace audit tool (v2.3.2 + my patch for arm64)
All those were already or will be soon posted separately.
Please review them as well for better understandings.
This code was tested on both 32-bit and 64-bit LE userland
in the following two ways:
1) basic operations with auditctl/autrace
# auditctl -a exit,always -S openat -F path=/etc/inittab
# auditctl -a exit,always -F dir=/tmp -F perm=rw
# auditctl -a task,always
# autrace /bin/ls
by comparing output from autrace with one from strace
2) audit-test-code (+ my workarounds for arm/arm64)
by running "audit-tool", "filter" and "syscalls" test categories.
Changes v1 -> v2:
* Modified to utilize "generic compat system call audit" [3/6, 4/6, 5/6]
Please note that a required header, unistd_32.h, is automatically
generated from unistd32.h.
* Refer to regs->orig_x0 instead of regs->x0 as the first argument of
system call in audit_syscall_entry() [6/6]
* Include "Add regs_return_value() in syscall.h" patch [2/6],
which was not intentionally included in v1 because it could be added
by "kprobes support".
