Bug ID: 27818
Summary: tapset function pgrp() not working with the bpf
runtime
Product: systemtap
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: bpf
Assignee: systemtap at sourceware dot org
Reporter: agentzh at gmail dot com
Target Milestone: ---
The pgrp() tapset function does not work with the bpf runtime:
```
[agentzh@fed32-min ~/git/systemtap.new 0 (master)]$ /opt/stap/bin/stap --bpf -e
'probe oneshot { println(pgrp()) }'
semantic error: unresolved function pgrp (similar: pp, gid, pn, cpu, pid):
identifier 'pgrp' at <input>:1:25
source: probe oneshot { println(pgrp()) }
^
Pass 2: analysis failed. [man error::pass2]
```
while the kernel runtime works:
```
[agentzh@fed32-min ~/git/systemtap.new 1 (master)]$ /opt/stap/bin/stap -e
'probe oneshot { println(pgrp()) }'
83822
```
It'll be great if we can have this covered in ebpf. Thanks!
