Subject: [PATCH 04/28] Fixed the wrong type used while comparing IPv4
addresses
src/tcs/rpc/tcstp/rpc.c:access_control() checks if peer's address is
INADDR_LOOPBACK. There are two issues with the current code:
1. For correctness, in_addr_t should be used instead of uint32_t.
2. memcmp(3) is passed sizeof(struct sockaddr_in) that is larger than
sizeof(in_add_r) (or sizeof(uin32_t) for that matter), so the call
always fails.
