sceRudpEnd takes no argument and shuts the library down; sceRudpTerminate takes a context id and releases that context. main had the two swapped, so a title calling sceRudpEnd() passed a stray register as a context id and the library stayed initialised. Evidence: - PS5 console measurement by hugodearaujo in #3073 (firmware 13.60): "After `sceRudpEnd()` all three return `0x80770001` again" (sceRudpGetMaxSegmentSize, sceRudpProcessEvents, sceRudpNetFlush). - AlexAltea/orbital cc408367da6a6ebbf5ac1ac559fefeadc73b2831 tools/ida/db_types.json:1971,1996: `int sceRudpEnd(void)`, `int sceRudpTerminate(int ctxId)`. - RPCS3 26098fb42d090cd522b4afcf3b754dd987c82978 rpcs3/Emu/Cell/Modules/cellRudp.cpp:108: `cellRudpEnd()` tears the library down. - AndnixSH/Vita3K-PS-Vita-OS-Fork c86ac732bc811057e690bed280c5076bdf95385e vita3k/modules/SceRudp/SceLibRudp.cpp:1032,1614: `sceRudpEnd()` clears every context, `sceRudpTerminate(int ctx_id)` erases one. The bodies are unchanged, only exchanged. guest_offline_imports now ends the library with sceRudpEnd(), and guest_rudp_status checks that sceRudpTerminate releases one context and sceRudpEnd all of them.
