boss:P also contains all of the commands from boss:U.

When Home Menu loads the SpotPass CBMD with Extended_Banner, it uses bossP command 0x040D0182 first. Then it uses GetNsDataHeaderInfoPrivileged, then ReadNsDataPrivileged for loading the actual banner data.

BOSS Service "boss:M"

Content Data Storage

SpotPass content for each application is stored under the extdata specified by BOSS:SetStorageInfo. That command and others verify that the PID associated with the current service session has access to the specified extdata by using FS:CheckAuthorityToAccessExtSaveData, returning an error on failure. This basically renders SpotPass unusable under user-processes(when initialized under those processes) which don't have access to any SD extdata(unless NAND extdata is used instead).

BOSS Tasks

The TaskID is a 8-byte buffer containing a string(normally including NUL-terminator).

When disabling SpotPass, applications use BOSSU:CancelTask then BOSSU:UnregisterTask, to delete each task.

NsDataId

This is an u32 ID for SpotPass content, used with the NsData service commands etc.
