| Single session services not really single session
| Several "critical" services (like fsp-ldr, fsp-pr, sm:m, etc) are meant to only ever hold a single session with a specific sysmodule. However, when a sysmodule dies, all its service session handles are released -- and thus killing the holder of a single session handle would allow one (via sm:hax etc) to get access to that service.
This was fixed in [[4.0.0]] by adding a semaphore to these critical single-session services, so that even if one gets access to them an error code will be returned when attempting to use any of their commands.
| With some way to access these services and kill their session holders: dumping sysmodule code, arbitrary service access, elevated filesystem permissions, etc.
