Bug ID: 21889
Summary: kernel bpf stress test
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: testsuite
Assignee: systemtap at sourceware dot org
Reporter: fche at redhat dot com
Target Milestone: ---
As per bug #2725, we know kernel kprobes have had a history of imperfect
robustness. With the bpf backend, we can & should try that again, namely to
check whether the kernel's kprobes + bpf interpreter can survive large
wildcards, longer operations, probe-read memory accesses. Stuff that should be
harmless, were it not for bugs.
