Description nucleo 2011-10-02 21:27:52 UTC
Description of problem:
iotop can not be run with non root user but with works fine.

Version-Release number of selected component (if applicable):
iotop-0.4.3-1.fc17

Steps to Reproduce:
1. Start iotop with non-root user
2.
3.
  
Actual results:
Traceback (most recent call last):
  File "/usr/bin/iotop", line 16, in <module>
    main()
  File "/usr/lib/python2.7/site-packages/iotop/ui.py", line 563, in main
    main_loop()
  File "/usr/lib/python2.7/site-packages/iotop/ui.py", line 553, in <lambda>
    main_loop = lambda: run_iotop(options)
  File "/usr/lib/python2.7/site-packages/iotop/ui.py", line 465, in run_iotop
    return curses.wrapper(run_iotop_window, options)
  File "/usr/lib/python2.7/curses/wrapper.py", line 43, in wrapper
    return func(stdscr, *args, **kwds)
  File "/usr/lib/python2.7/site-packages/iotop/ui.py", line 457, in run_iotop_window
    process_list = ProcessList(taskstats_connection, options)
  File "/usr/lib/python2.7/site-packages/iotop/data.py", line 373, in __init__
    self.update_process_counts()
  File "/usr/lib/python2.7/site-packages/iotop/data.py", line 429, in update_process_counts
    stats = self.taskstats_connection.get_single_task_stats(thread)
  File "/usr/lib/python2.7/site-packages/iotop/data.py", line 158, in get_single_task_stats
    reply = GeNlMessage.recv(self.connection)
  File "/usr/lib/python2.7/site-packages/iotop/genetlink.py", line 50, in recv
    msg = conn.recv()
  File "/usr/lib/python2.7/site-packages/iotop/netlink.py", line 229, in recv
    raise err
OSError: Netlink error: Operation not permitted (1)


Expected results:
iotop should work for any user.

Additional info:
On F15 machine iotop-0.4.3-1.fc15 works fine with non-root user so maybe something broken on Rawhide machine but I don't know what can be broken there.

Comment 1 Michel Alexandre Salim 2011-10-06 09:20:53 UTC
Seems to have something to do with the newer kernel versions; I run a self-compiled 3.1.0-rc kernel on my F-15 machine and it's affected by this problem too, with iotop-0.4.3-1.fc15

Comment 2 nucleo 2011-10-06 13:08:15 UTC
So adding kernel maintainers to CC.

Comment 3 Michal Hlavinka 2011-10-06 13:44:05 UTC
closing as duplicate of abrt report, because abrt will cc more people there
