Add a process name to the log of cgrulesengd daemon.

2009-07-07T14:35:21+00:00

Hi,

Current cgrulesengd daemon changes the cgroup of each process by a rule
based on uid, gid, and process name. And it is good that the log of the
daemon contains a process name with uid and gid.
This patch adds a process name to the log message.

Thanks

Reduce "Cgroup change for PID:X, UID:X, GID:X FAILED!" messages.

2009-07-07T14:35:21+00:00

Hi,

Changelog since v1:
===================
 * Rebase the latest code.
 * Cleanup.

The log message "Cgroup change for PID:X, UID:X, GID:X FAILED!" is output
by cgrulesengd daemon, even if a process finished already and that is not
a problem.
This patch prevents the daemon from outputting this spam log message.

* Reference
  [PATCH 2/2] Reduce "Cgroup change for PID:X, UID:X, GID:X FAILED!" messages.

Cleanup: find better name for CGRULE_CGRED_TEMP_FILE

2009-07-01T15:04:49+00:00

Rename CGRULE_CGRED_TEMP_FILE to CGRULE_CGRED_SOCKET_PATH to better describe
the macro usage - it's not a temporary file, it's a socket.

Add the handler of unchanged process to cgrulesengd daemon.

2009-06-29T11:17:32+00:00

Hi,

Changelog of v6:
================
 * No change.

Changelog of v5:
================
 * No change.

Changelog of v4:
================
 * Add the comment "FIXME: Change the temporary file to configurable one."
 * Define the number of allocation.

Changelog of v3:
================
 * Set the value 0x1 to CGROUP_DAEMON_UNCHANGE_CHILDREN flag.

Changelog of v2:
================
 * New patch.

Description:
============
This patch adds the handler of unchanged process to the cgrulesengd daemon.
By this patch, the daemon does not change a process which is executed by
'cgexec' command, because it is possible to notify the unchanged process to
the daemon by using "unix domain socket".

Thanks

around the netlink method.

Cleanup: Integrate similar code to cgroup_get_uid_gid_from_procfs().

2009-06-08T09:03:25+00:00

CHANGELOG of v2.1:
================
* Rebase the patch for commit '340feae163c4797a6cb1247b3812c1ccdc52fa41'.

There are some similar functions for getting process's data (uid, gid) from
/proc//status file, so this patch integrates these functions into one
cgroup_get_uid_gid_from_procfs().

Add options to enable/disable various build targets.

2009-05-25T07:48:34+00:00

By default, everything is compiled. I want to add options to ./configure,
which can selectively disable tools, daemon and pam module. The library
itself is mandatory component and cannot be disabled.


Usage:
./configure --help
./configure --disable-tools --disable-pam --disable-daemon
