Netty: Unix-socket fd receive leaks descriptors when peer sends two at once

nettyunixsocketrecvFd sets msgcontrol to char controlCMSGSPACEsizeofint line 940 — 24 bytes on 64-bit Linux. A peer-sent SCMRIGHTS cmsg carrying two ints has cmsglen = CMSGLEN8 = 24, which fits exactly with no MSGCTRUNC, so the kernel installs both fds in the receiving process. The subsequent che...
