Bug ID: 19753
Summary: redirect udp.*msg probes to netfilter.*
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: tapsets
Assignee: systemtap at sourceware dot org
Reporter: fche at redhat dot com
Target Milestone: ---
As recently discussed on the mailing list, the current kprobes-based
udp.{send,recv}msg probes are less than ideal in that they sometimes pass along
null/not-yet-set host/port information. We should provide an alternative
(conditional on %( systemtap_v >= "3.0" ... %) that delegates to
netfilter.ip.local_{in,out} (?) instead of kprobes. We should be able to get
pretty much the same information, and without debuginfo.
