CtrlHelloRequest.key was declared `Data` in controller.capnp. This project's capnp-c backend silently no-ops encoding of Data-typed fields without zero-initializing the caller's local struct, leaving an uninitialized capn_ptr that write_CtrlHelloRequest unconditionally wrote to the wire -- SIGSEGV in capn_setp/copy_ptr. Hit live: ctrl-1 won its Raft election and crashed calling ha_send_ctrlhello_to_all_standbys(). Same bug class as bug-1504/bug-1505, both already fixed by switching the field from Data to List(UInt8); bug-1505's own writeup had flagged CtrlHelloRequest.key as a known-but-unfixed instance. Applied the identical fix here: Data -> List(UInt8) + keyLen companion in the schema, uint8_t*/key_len in typemap.h. The field is unused in production (always NULL), so no consumer code changed. Added a round-trip regression test covering both the NULL-key production shape and real key content. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> |
