[Bug 218320] Re: Hangs at "Starting kernel log daemon..." in OpenVZ container

[Jakob Unterwurzacher]

in ksym_mod.c we have

        ksyms = fopen(KSYMS, "r");

	if ( ksyms == NULL )
	{
		if ( errno == ENOENT )
			Syslog(LOG_INFO, "No module symbols loaded - "
			       "kernel modules not enabled.\n");
		else
			Syslog(LOG_ERR, "Error loading kernel symbols " \
			       "- %s\n", strerror(errno));
		fclose(ksyms);
		return(0);
	}

We fclose a NULL file descriptor?

On OpenVZ, /proc/kallsyms (=KSYMS) does not exist. So it segfaults here.

** Attachment added: "Do no fclose null file descriptor"

** Summary changed:

- Hangs at "Starting kernel log daemon..." in OpenVZ container
+ klogd segfaults on startup in OpenVZ container, makes boot+upgrade hang at "Starting kernel log daemon..."
