Use memset to initialize sigaction struct

2010-03-12T15:44:17+00:00

The sa_restorer field is not present on some architectures, like alpha.
By using memset, the structure is initialized appropriately regardless of
struct contents.

Fix compilation outside of source directory

2009-12-16T08:36:39+00:00

Configure script can be invoked outside of source directory, which allows
to compile sources without spoiling the source directory with compilation
artifacts (like .o files). This patch tries to fix our Makefiles to allow
this to work.

You can test it in current GIT checkout (in the root dir):
# mkdir build; cd build; ../configure; make

As result, you should see all binary files in the 'build' directory.

Restrict the effective range of SIGUSR2 signal.

2009-10-04T14:36:00+00:00

Hi,

If a cgrulesengd daemon receives a SIGUSR2 signal (for reloading rules
configuration) while waiting in select(), a daemon finishes incorrectly
due to an "Interrupted system call" error.
If applying a patch "Add the strings of errno to cgrulesengd daemon's
message." and running `service cgred reload`, you can see the message
"selecting error: Interrupted system call". This patch fixes the problem.

There were some problems the deadlock happens related to a SIGUSR2 signal
and they have been fixed by the followings already:

* [PATCH] Fix the deadlock of vsyslog() call.
  http://libcg.git.sourceforge.net/git/gitweb.cgi?p=libcg;a=commit;h=70111cd03653c3ceab9d907c14fa35e5881b2735
* [PATCH] Fix the deadlock of rl_lock.
  http://libcg.git.sourceforge.net/git/gitweb.cgi?p=libcg;a=commit;h=0241c6f1df5068c006f756005c8e7faa63058c27

The above two patches fixed the problems by protecting the important
codes from receiving a SIGUSR2 signal. But this way was not good, because
the protecting code will be necessary if increasing the important codes.

Instead of protecting the important codes, this patch restricts the
effective range of receiving SIGUSR2 signal. So we will not need to add
a new protecting code by this patch.

Add the strings of errno to cgrulesengd daemon's message.

2009-10-04T14:36:00+00:00

Hi,

This patch adds  the strings of errno to cgrulesengd daemon's message.

For investigating a problem that cgrulesengd daemon finishes by
`service cgred reload`, I added the strings of errno to the daemon's
message. This strings were useful for investigating.

Thanks

Remove unnecessary includes from libcgroup.h

2009-08-29T05:20:25+00:00

libcgroup.h includes some header files, which are not then used. These should
be removed, resp. moved to the source files where they are actually needed.

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.
