Date: Tue, 18 Nov 2014 14:19:39 +0800 Message-ID: <1416291582-74982-1-git-send-email-wangnan0@huawei.com> X-Mailer: git-send-email 1.8.4 MIME-Version: 1.0 Content-Type: text/plain X-Originating-IP: [10.107.197.247] X-CFilter-Loop: Reflected Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org This is part of version 8 of 'ARM: kprobes: enable OPTPROBES for ARM32'. Its main goal is introducing checker mechanism to give a chance to detail check each probed instructions. Different from previous version, this series redesign stack checker following Tixy's advise: https://lkml.org/lkml/2014/10/27/662 Previous discussion can be found in following threads: https://lkml.org/lkml/2014/10/25/48 https://lkml.org/lkml/2014/10/22/254 https://lkml.org/lkml/2014/8/27/255 https://lkml.org/lkml/2014/8/12/12 https://lkml.org/lkml/2014/8/8/992 https://lkml.org/lkml/2014/8/8/5 https://lkml.org/lkml/2014/8/5/63 Wang Nan (3): ARM: kprobes: introduces checker ARM: kprobes: collects stack consumption for store instructions ARM: kprobes: disallow probing stack consuming instructions arch/arm/include/asm/kprobes.h | 1 - arch/arm/include/asm/probes.h | 13 ++++ arch/arm/kernel/Makefile | 6 +- arch/arm/kernel/entry-armv.S | 3 +- arch/arm/kernel/kprobes-arm.c | 3 + arch/arm/kernel/kprobes-test-arm.c | 16 +++-- arch/arm/kernel/kprobes-thumb.c | 4 ++ arch/arm/kernel/kprobes.c | 15 ++++- arch/arm/kernel/kprobes.h | 7 +- arch/arm/kernel/probes-arm.c | 5 +- arch/arm/kernel/probes-arm.h | 3 +- arch/arm/kernel/probes-checkers-arm.c | 99 ++++++++++++++++++++++++++++ arch/arm/kernel/probes-checkers-common.c | 87 +++++++++++++++++++++++++ arch/arm/kernel/probes-checkers-thumb.c | 108 +++++++++++++++++++++++++++++++ arch/arm/kernel/probes-checkers.h | 54 ++++++++++++++++ arch/arm/kernel/probes-thumb.c | 10 +-- arch/arm/kernel/probes-thumb.h | 6 +- arch/arm/kernel/probes.c | 61 ++++++++++++++++- arch/arm/kernel/probes.h | 11 +++- arch/arm/kernel/uprobes.c | 2 +- 20 files changed, 488 insertions(+), 26 deletions(-) create mode 100644 arch/arm/kernel/probes-checkers-arm.c create mode 100644 arch/arm/kernel/probes-checkers-common.c create mode 100644 arch/arm/kernel/probes-checkers-thumb.c create mode 100644 arch/arm/kernel/probes-checkers.h -- 1.8.4
