Bug #: 14491
Summary: Add a proper stapdyn transport layer
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: runtime
AssignedTo: systemtap@sourceware.org
ReportedBy: jistone@redhat.com
Blocks: 14178
Classification: Unclassified
Right now there's not transport layer at all in stapdyn. Communication is only
going stapdyn->module via inferior calls, and script output is writing directly
on the target's stdout/err.
We really need a means for bidirectional communication, both for control
messages and for general script output. For a first draft, I propose listening
on a socket in stapdyn, opening that in the target with an inferior call, and
then send messages just as we do with staprun and kernel modules.
