+ Statement explaining the impact
+ =====================
- Looking at the smart code shows that the problem is in
- plugins/detectsys.py:
+ This bug affects anybody with the rpm package installed, or even removed
+ but not purged (see below how to reproduce). The landscape package
+ reporter (which is what is crashing) reports to the landscape server the
+ packages installed and available on each managed machine. If it crashes,
+ then the machine will show up in landscape has having no packages at
+ all.
- def detectRPMSystem():
- dir = os.path.join(sysconf.get("rpm-root", "/"), "var/lib/rpm")
- if os.path.isdir(dir):
- for alias in sysconf.keys("channels"):
- if sysconf.get(("channels", alias, "type")) == "rpm-sys":
- break
- else:
- sysconf.set("channels.rpm-sys", {
- "type": "rpm-sys",
- "name": "RPM System"
- })
+ How the bug has been addressed
+ ======================
- because of the sysconf.set call in the else: branch.
+ By conditionally loading the rpm smart plugin if it's available.
- affects landscape-client
- importance medium
- milestone 1.3.2
+ Detailed instructions how to reproduce the bug
+ ==============================
+
+ If the /var/lib/rpm directory exists on the system (this happens for instance
if
+ the "rpm" package is installed or removed but not purged), the call to
smart.initPlugins() in landscape/package/facade.py makes the
landscape-client-reporter crash.
