Bug ID: 16309
Summary: SELinux prevents stap-serverd from opening the current
dir when spawning processes
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: server
Assignee: systemtap at sourceware dot org
Reporter: jlebon at redhat dot com
When stap-serverd tries to start stap or even zip, the open() call to "." in
spawn_and_wait fails with EACCES, and the log shows "Error in spawn getcwd".
This does not occur if in permissive mode.

--- Comment #1 from Jonathan Lebon <jlebon at redhat dot com> ---
This issue occurs because /usr/bin/stap-server does a cd to /usr/lib/modules
when treating the -i option. This cwd is inherited by stap-serverd, which does
not have the blessing of SELinux to open that directory. Fixed in commit
481d154 by always changing to / before starting stap-serverd.
