[PATCH] Process Events Connector This patch adds a connector that reports fork, exec, id change, and exit events for all processes to userspace. It replaces the fork_advisor patch that ELSA is currently using. Applications that may find these events useful include accounting/auditing (e.g. ELSA), system activity monitoring (e.g. top), security, and resource management (e.g. CKRM).

proc connector: add event for process becoming session leader The act of a process becoming a session leader is a useful signal to a supervising init daemon such as Upstart. While a daemon will normally do this as part of the process of becoming a daemon, it is rare for its children to do so. When the children do, it is nearly always a sign that the child should be considered detached from the parent and not supervised along with it. The poster-child example is OpenSSH; the per-login children call setsid() so that they may control the pty connected to them. If the primary daemon dies or is restarted, we do not want to consider the per-login children and want to respawn the primary daemon without killing the children. This patch adds a new PROC_SID_EVENT and associated structure to the proc_event event_data union, it arranges for this to be emitted when the special PIDTYPE_SID pid is set.

connector: add an event for monitoring process tracers This change adds a procfs connector event, which is emitted on every successful process tracer attach or detach. If some process connects to other one, kernelspace connector reports process id and thread group id of both these involved processes. On disconnection null process id is returned. Such an event allows to create a simple automated userspace mechanism to be aware about processes connecting to others, therefore predefined process policies can be applied to them if needed. Note, a detach signal is emitted only in case, if a tracer process explicitly executes PTRACE_DETACH request. In other cases like tracee or tracer exit detach event from proc connector is not reported.

void proc_ptrace_connector(struct task_struct *task, int which_id);
connector: add comm change event report to proc connector Add an event to monitor comm value changes of tasks. Such an event becomes vital, if someone desires to control threads of a process in different manner. A natural characteristic of threads is its comm value, and helpfully application developers have an opportunity to change it in runtime. Reporting about such events via proc connector allows to fine-grain monitoring and control potentials, for instance a process control daemon listening to proc connector and following comm value policies can place specific threads to assigned cgroup partitions. It might be possible to achieve a pale partial one-shot likeness without this update, if an application changes comm value of a thread generator task beforehand, then a new thread is cloned, and after that proc connector listener gets the fork event and reads new thread's comm value from procfs stat file, but this change visibly simplifies and extends the matter.
