-Subject: [PATCH 2/4] Fix memory corruption in PMAP_CALLIT code
-
- - A PMAP_CALLIT call comes in on IPv4 UDP
- - rpcbind duplicates the caller's address to a netbuf and stores it in
-   FINFO[0].caller_addr. caller_addr->buf now points to a memory region A
-   with a size of 16 bytes
- - rpcbind forwards the call to the local service, receives a reply
- - when processing the reply, it does this in xprt_set_caller:
-    xprt->xp_rtaddr = *FINFO[0].caller_addr
-   It sends out the reply, and then frees the netbuf caller_addr and
-   caller_addr.buf.
-   However, it does not clear xp_rtaddr, so xp_rtaddr.buf now refers
-   to memory region A, which is free.
- - When the next call comes in on the UDP/IPv4 socket, svc_dg_recv will
-   be called, which will set xp_rtaddr to the client's address.
-   It will reuse the buffer inside xp_rtaddr, ie it will write a
-   sockaddr_in to region A
-
-Some time down the road, an incoming TCP connection is accepted,
-allocating a fresh SVCXPRT. The memory region A is inside the
-new SVCXPRT
-
- - While processing the TCP call, another UDP call comes in, again
-   overwriting region A with the client's address
- - TCP client closes connection. In svc_destroy, we now trip over
-   the garbage left in region A
-
-We ran into the case where a commercial scanner was triggering
-occasional rpcbind segfaults. The core file that was captured showed
-a corrupted xprt->xp_netid pointer that was really a sockaddr_in.
