Message-ID: <1762@umcp-cs.UUCP> Date: Mon, 10-Dec-84 04:07:02 EST Article-I.D.: umcp-cs.1762 Posted: Mon Dec 10 04:07:02 1984 Date-Received: Wed, 12-Dec-84 03:28:26 EST Distribution: net Organization: U of Maryland, Computer Science Dept., College Park, MD Lines: 16 I've been rewriting the parts of the socket stuff dealing with atomic and connectionless protocols, and discovered this interesting tidbit: if you receive, in AF_UNIX, with MSG_PEEK, a message containing "rights" (file descriptors), you get those descriptors then and there. If you then receieve without MSG_PEEK, you get them *again*, with apparently disastrous effect. Is this not a bug? How come I haven't seen anything posted about it? (There are several other bugs in soreceive dealing with MSG_PEEK, too.) -- (This line accidently left nonblank.)
