conntrackd: add support to display statistics on existing child processes

2009-06-11T18:33:14+00:00

This patch adds the ability to dump the list of existing child processes. In general, it would be hard to display one since child processes are generally forked for very specific tasks, like commit and flush operations, and they have very limited lifetime. However, this can be handy for debugging problems. Signed-off-by: Pablo Neira Ayuso

conntrackd: allow to limit the number of simultaneous child processes

2009-06-11T17:34:50+00:00

This patch allows to limit the number of simultaneous child processes. This is required by the next patch that replaces disposable handlers to commit and flush with permanent handlers. Signed-off-by: Pablo Neira Ayuso

conntrackd: block signals during the access to the process list

2009-06-11T17:27:44+00:00

A child process may finish while we are walking on the process list. This fixes possible concurrency problems. Signed-off-by: Pablo Neira Ayuso

conntrackd: add missing initialization of PID in process infrastructure

2009-06-11T17:26:49+00:00

In 0374398fd14bf587d80d9d31e361e266e69387c8, I introduced the process infrastructure. However, that patch missed the PID initialization. Without this patch, the process structures are never released. Signed-off-by: Pablo Neira Ayuso

conntrackd: add child process infrastructure

2009-05-23T10:09:06+00:00

This patch adds a simple infrastructure that allows to account the child processes that have been forked. This also includes a callback handler that can be registered that is called once the child process finishes. We can extended this later to include an alarm to limit the maximum lifetime of a forked child process. This is good to ensure that child processes behave timely. Signed-off-by: Pablo Neira Ayuso
