There are RFC uretprobes implementation. I'd be grateful for review. RFCv1: https://lkml.org/lkml/2012/12/21/133
I've intentionally removed the retprobe bypass logic, it requires a bit more work. not fixed since last prior RFC review: unify xol_get_trampoline_slot() and xol_take_insn_slot() protect uprobe in prepare_uretprobe() v2 changes: introduced rp_handler(), get rid of return_consumers get rid of uretprobe_[un]register() introduced arch_uretprobe_get_sp() removed uprobe_task->doomed, kill task immediately fix arch_uretprobe_hijack_return_addr()'s returns address the v1 minor issues thanks, Anton Arapov (5): uretprobes/x86: hijack return address uretprobes: trampoline implementation uretprobes: return probe entry, prepare uretprobe uretprobes: invoke return probe handlers arch/x86/include/asm/uprobes.h | 6 ++ arch/x86/kernel/uprobes.c | 48 +++++++++++ include/linux/uprobes.h | 9 ++ kernel/events/uprobes.c | 181 ++++++++++++++++++++++++++++++++++++++++- 4 files changed, 241 insertions(+), 3 deletions(-) -- 1.8.0.2 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
