See below.) This patchset contains some patches commonly applied for audit and ftrace. Patch [1/4] defines syscall trace related TIF_* flags in order to add hooks, including ftrace, audit and seccomp, later on. Those features will be implemented in separate patchsets, but it's safe to check for all TIF_* now because they can not be turned on anyway. Patch [2/4] doesn't change a behavior but make it easy and manageable to confirm we invoke those hooks in correct order by splitting syscall_trace(). Patch [3/4] adds a commonly used function, which returns a return value of system call. Patch [4/4] removes is_compat_task from asm/compat.h to avoid conflicted definitions. Changes v5 -> v6: * renamed a temporary variable's name to more meaningful one [2/4] Changes v4 -> v5: * added the following patch from my seccomp patch since it is required for audit and ftrace in case of !COMPAT, too. [4/4] "arm64: is_compat_task is defined both in asm/compat.h and linux/compat.h" Changes v3 -> v4: * added "arm64: split syscall_trace() into separate functions for enter/ exit", which is just a preparation for adding syscall trace hooks later. Changes v2 -> v3: * reverted a change in syscall_trace() in v1 [1/2] * added "arm64: Add regs_return_value() in syscall.h" patch which was previously included in audit patch [2/2] Changes v1 -> v2: * added a guard against TIF_SYSCALL_TRACE at tracehook_report_syscall_*() * renamed _TIF_WORK_SYSCALL to _TIF_SYSCALL_WORK AKASHI Takahiro (4): arm64: make a single hook to syscall_trace() for all syscall features arm64: split syscall_trace() into separate functions for enter/exit arm64: Add regs_return_value() in syscall.h arm64: is_compat_task is defined both in asm/compat.h and linux/compat.h arch/arm64/include/asm/compat.h | 5 ---- arch/arm64/include/asm/ptrace.h | 5 ++++ arch/arm64/include/asm/thread_info.h | 13 +++++++++ arch/arm64/kernel/entry.S | 15 +++++----- arch/arm64/kernel/hw_breakpoint.c | 2 +- arch/arm64/kernel/process.c | 1 + arch/arm64/kernel/ptrace.c | 51 ++++++++++++++++++++-------------- arch/arm64/kernel/signal.c | 2 +- 8 files changed, 58 insertions(+), 36 deletions(-) -- 1.7.9.5 From mboxrd@z Thu Jan 1 00:00:00 1970 From: takahiro.akashi@linaro.org (AKASHI Takahiro) Date: Wed, 30 Apr 2014 18:51:28 +0900 Subject: [PATCH v6 0/4] arm64: prerequisites for audit and ftrace In-Reply-To: <1394861948-28712-1-git-send-email-takahiro.akashi@linaro.org> References: <1394861948-28712-1-git-send-email-takahiro.akashi@linaro.org> Message-ID: <1398851492-16345-1-git-send-email-takahiro.akashi@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org (This patchset was already acked by the maintainer along with a minor typo fix.
