Bug ID: 21890
Summary: bpf uprobes support
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: runtime
Assignee: systemtap at sourceware dot org
Reporter: fche at redhat dot com
Target Milestone: ---
Current bpf code can handle kprobes & kretprobes. It should not be hard to
bring up uprobes/uretprobes; the translator's side is almost identical. The
.bo symbol-name encoding would be fine too, as long as path names are included.
The stapbpf kprobe* functions just(tm) need to be forked or parametrized into
uprobe* ones (including those that manipulate the /sys/kernel/debug/tracing
files).
