Mostly uretprobes. "perf probe -x file sym%return" works like kretprobes.
TODO: longjmp() is not supported, currently we assume that the probed
function returns, this needs another series.
Also the powerpc fixes plus a couple of cleanups/optimizations in uprobes
and trace_uprobes.
Ananth N Mavinakayanahalli (3):
uprobes: Add trap variant helper
uprobes/powerpc: Teach uprobes to ignore gdb breakpoints
uprobes/powerpc: Remove additional trap instruction check
Anton Arapov (9):
uretprobes: Introduce uprobe_consumer->ret_handler()
uretprobes: Reserve the first slot in xol_vma for trampoline
uretprobes/x86: Hijack return address
uretprobes/powerpc: Hijack return address
uretprobes: Return probe entry, prepare_uretprobe()
uretprobes: Return probe exit, invoke handlers
uretprobes: Limit the depth of return probe nestedness
uretprobes: Remove -ENOSYS as return probes implemented
uretprobes: Documentation update
Oleg Nesterov (18):
uprobes: Use file_inode()
uprobes: Turn copy_opcode() into copy_from_page()
uprobes: Change __copy_insn() to use copy_from_page()
uprobes: Kill the unnecesary filp != NULL check in __copy_insn()
uprobes: Introduce copy_to_page()
uprobes: Change write_opcode() to use copy_*page()
uprobes/tracing: Kill the pointless task_pt_regs() calls
uprobes/tracing: Kill the pointless seq_print_ip_sym() call
uprobes/tracing: Kill the pointless local_save_flags/preempt_count calls
uprobes/tracing: Generalize struct uprobe_trace_entry_head
uprobes/tracing: Introduce uprobe_{trace,perf}_print() helpers
uprobes/tracing: Introduce is_ret_probe() and uretprobe_dispatcher()
uprobes/tracing: Make uprobe_{trace,perf}_print() uretprobe-friendly
uprobes/tracing: Make register_uprobe_event() paths uretprobe-friendly
uprobes/tracing: Make seq_printf() code uretprobe-friendly
uprobes/tracing: Change create_trace_uprobe() to support uretprobes
uprobes/tracing: Don't pass addr=ip to perf_trace_buf_submit()
uprobes/perf: Avoid perf_trace_buf_prepare/submit if ->perf_events is
empty
