Subject: [RFC PATCH v3 00/26] Early kprobe: enable kprobes at very early booting stage.
Date: Fri, 13 Feb 2015 13:38:27 +0800 [thread overview]
Message-ID: <1423805907-61335-1-git-send-email-wangnan0@huawei.com> (raw)
In-Reply-To: <1423743476-11927-1-git-send-email-wangnan0@huawei.com>
I fell very sorry for people who reviewed my v2 patch series yesterday
at https://lkml.org/lkml/2015/2/12/234 because I didn't provide enough
information in commit log. This v3 patch series add those missing
commit messages. There are also 2 small fix based on v2:
1. Fixes ftrace_sort_mcount_area. Original patch doesn't work for module.
2. Wraps setting of kprobes_initialized in stop_machine() context.
Wang Nan (26):
kprobes: set kprobes_all_disarmed earlier to enable re-optimization.
kprobes: makes kprobes/enabled works correctly for optimized kprobes.
kprobes: x86: mark 2 bytes NOP as boostable.
ftrace: don't update record flags if code modification fail.
ftrace/x86: Ensure rec->flags no change when failure occures.
ftrace: sort ftrace entries earlier.
ftrace: allow search ftrace addr before ftrace fully inited.
ftrace: enable make ftrace nop before ftrace_init().
ftrace: allow fixing code update failure by notifier chain.
ftrace: x86: try to fix ftrace when ftrace_replace_code.
early kprobes: introduce kprobe_is_early for futher early kprobe use.
early kprobes: Add an KPROBE_FLAG_EARLY for early kprobe.
early kprobes: ARM: directly modify code.
early kprobes: ARM: introduce early kprobes related code area.
early kprobes: x86: directly modify code.
early kprobes: x86: introduce early kprobes related code area.
early kprobes: introduces macros for allocing early kprobe resources.
early kprobes: allows __alloc_insn_slot() from early kprobes slots.
early kprobes: perhibit probing at early kprobe reserved area.
early kprobes: core logic of eraly kprobes.
early kprobes: add CONFIG_EARLY_KPROBES option.
early kprobes: introduce arch_fix_ftrace_early_kprobe().
early kprobes: x86: arch_restore_optimized_kprobe().
early kprobes: core logic to support early kprobe on ftrace.
early kprobes: introduce kconfig option to support early kprobe on
ftrace.
kprobes: enable 'ekprobe=' cmdline option for early kprobes.
