Bug ID: 22392
Summary: bpf translator: segfault possible when performing
operation on result of void function call.
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: translator
Assignee: systemtap at sourceware dot org
Reporter: amerey at redhat dot com
Target Milestone: ---
example:
stap --runtime=bpf -u -e 'probe kernel.function("sys_read") { x =
printf("test\n") }'
When translating the assignment, the bpf translator attempts to dereference a
NULL value. We want to perform checks similar to the default translator which
instead raises a "void value not ignored as it ought to be" error when
translating the example script.
