+Subject: [PATCH] proto: use uint32_t offsets and message lengths
+
+As the protocol imposes a hard 32-bit limit on message size, and the
+affected functions' offset value can never go negative, just use
+uint32_t for the lot. Fully fixes the signedness errors partially
+corrected in b8218e3fae78fc9977fa867a121ae11b2ab35d4e while avoiding
+the possibility of silent truncation (either through an overlong
+message or running on a big-endian host).
