{enable | disable}

enable

When enabled, the system will perform the following actions (using proxyd as an example):

1. Backup "/bin/proxyd" to "/bin/proxyd.bak"

2. Create symbolic link between "/bin/proxyd" and "/var/log/debug/symbol/asan/bin/proxyd"

3. Kill proxyd

This cause the proxyd daemon to respawn with the ASAN version. You leave the system in its state and let the ASAN version of proxyd daemon run and collect memory violation events.

Please note the changes above is not persistent across reboot. If the system is reloaded, the normal version of daemon will be running.

disable

Once the data is collected, you use disable to revert back to the normal daemon. The system will perform the following actions (using proxyd as an example):

1. Rename "/bin/proxyd.bak" to "/bin/proxyd"

2. Kill proxyd

This cause the daemon to respawn with the original executable.

Please note that respawning will cause traffic interruption.
