Bug ID: 18889
Summary: lost ability to probe kernel module initializers
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: runtime
Assignee: systemtap at sourceware dot org
Reporter: fche at redhat dot com
Target Milestone: ---
On recent kernels, a probe requested on module .init.* functions no longer
receives hits. This appears to be because the kernel MODULE_STATE_COMING
notification is coming too early (before the module_sect_attrs are set), so we
cannot relocate symbols against .init.*, and thus cannot place probes. The
bz6503.* test case was too permissive to let us discover this immediately. The
kernel change that broke stap has not yet been identified.
