/etc/init.d/heartbeat status calls heartbeat -s
for non root users this worked fine before 2.1.x (in etch 2.0.7) it returned
the same value for root and non-root users
After 2.1.x it returns :
"heartbeat is stopped. No process"
even tho its wrong.
The pid file access rights are still the same
ls -la /var/run/heartbeat.pid
-rw-r--r-- 1 root root 11 2009-02-12 11:47 /var/run/heartbeat.pid
it seems an additional check has been added to cl_pidfile.c, previously only
long running_hb_pid = cl_read_pidfile(PIDFILE);
was called - i.e. only the value of the pidfile - without verifying if the pid
was running at all.
The additional check is propbably this:
if (CL_KILL(pid, 0) < 0 && errno == ESRCH) {
goto bail;
}
this calls kill -s 0 HEARTBEAT_PID
which returns
kill: (HEARTBEAT_PID) - Operation not permitted
which is not verified at all in the cl_pidfile.c.
The above check should be changed, using signal 0 requires permission as root
user.
But, it should be possible to query if the process is running without an issue
- since ps aux as non-root user also returns if a process is running.
The main issue is, that programs which interpret heartbeat status are wrongly
led that heartbeat isnt running.
