In Security

With the unexpectedly quick release of an iOS 9 jailbreak, users reported a boot loop issue when installing SSL Kill Switch. I think this was caused by underlying changes to the OS, rather than the tweak itself. Saurik subsequently updated Cydia Substrate and apparently made some changes to MobileLoader, the tweak injection mechanism, as SSL Kill Switch stopped working with following error in the logs:

MS:Error: extension does not have filter

As opposed to previous versions of Cydia Substrate, it seems like tweaks now must provide a plist filter or they won’t be loaded into any processes. Hence, I added the following filter for SSL Kill Switch:

Filter = {
  Bundles = (com.apple.UIKit);
};

This fixed the issue, with the side-effect that SSL Kill Switch will no longer be injected into processes that don’t link UIKit (ie. processes with no UI, such as system daemons like itunesd). If you need to use SSL Kill Switch in a daemon, you will need to modify the filter first and then recompile the tweak.
