Command to regenerate the metadata file when the session is running.

Account the lost packets in snapshot mode
When working in flight-recorder, we cannot rely on the absolute sequence
number because we only extract the content of the ring buffer
periodically. Moreover, we don't want to account the lost packets at the

Fix: tests: use SIGSTOP for crash extraction test
Ensure that SIGKILL being received only by some consumer processes don't
trigger clean shutdown of other consumer processes (due to hang up of
communication FD by the session daemon).
Fix this by invoking a SIGSTOP on both sessiond and consumerd, and wait
until we see those process state change to "stopped" before proceeding
to send the SIGKILL.

Fix: Only save kernel enablers in session configuration
The session configuration serialization currently saves the
kernel enablers along with all enabled syscalls. In the case
where a syscall would be enabled with a given filter, this would
result in two events being enabled:
1) the syscall with its filter expression (the enabler)
2) the syscall on its own (an enabled syscall)

traced regardless of the filter's evaluation.
