Bug #: 13186
Summary: systemtap does not correctly point out offending
structure when accidentally dereferencing a structure
as a string
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: translator
AssignedTo: systemtap@sourceware.org
ReportedBy: anish@chelsio.com
Classification: Unclassified
probe point :
printf("%s : %s\n",thread_indent(1),kernel_string($kobj->dentry->d_name))
error message :
Pass 1: parsed user script and 76 library script(s) using
138788virt/22212res/2784shr kb, in 140usr/10sys/152real ms.
semantic error: 'struct qstr' is being accessed instead of a member: identifier
'$kobj' at /tmp/sysfs.stp:14:53
source: printf("%s :
%s\n",thread_indent(1),kernel_string($kobj->dentry->d_name))
^
Here d_name is a structure of type qstr; which is the offending dereference
however the translator points to $kobj instead of d_name.
