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.

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.

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.

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. Signed-off-by: Jan Safranek <jsafrane@redhat.com> Signed-off-by: Dhaval Giani <dhaval@linux.vnet.ibm.com>
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 Ken'ichi Ohmichi Signed-off-by: Ken'ichi Ohmichi <oomichi@mxs.nes.nec.co.jp> Signed-off-by: Dhaval Giani <dhaval@linux.vnet.ibm.com>
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. http://sourceforge.net/mailarchive/message.php?msg_name=4A10EE7E.60403%40mxs.nes.nec.co.jp Thanks Ken'ichi Ohmichi Signed-off-by: Ken'ichi Ohmichi <oomichi@mxs.nes.nec.co.jp> Signed-off-by: Dhaval Giani <dhaval@linux.vnet.ibm.com>

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".

Changelog of v3: ================ * No change. Changelog of v2: ================ * New patch. Description: ============ This patch separates the netlink method for the readability, because the later patch [PATCH 6/9] adds "unix domain socket" handling method around the netlink method.
