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
