When support for send_cert was added in 4b9453b, the $send_cert variable was inadvertently global. Make it local to avoid polluting the global namespace and make the code easier to reason about. Fixes: 4b9453b ("strongswan: Add support for send_cert option") Signed-off-by: Kevin Locke <[email protected]>
$overtime has been used since swanctl.init was added in f9d91f1. However, there's no need for it to be global. Make it local like the other config variables to avoid polluting the global namespace and make the code easier to reason about. Fixes: f9d91f1 ("strongswan: migrate to swanctl configs") Signed-off-by: Kevin Locke <[email protected]>

$overtimeand$send_certare only used inconfig_remote()inswanctl.init. However, unlike the other local option variables, they are not declared local. This PR does so for consistency, to avoid global namespace pollution, and make the code easier to reason about.For reference,
$overtimewas added in f9d91f1,$send_certin 4b9453b.Thanks for considering,
Kevin
