Brad Hubbard ed6b0fe710 Use calloc to allocate xports (BZ #17542) ... If xports is NULL in xprt_register we malloc it but if sock > _rpc_dtablesize() that memory does not get initialised and may in theory contain any value. Later we make a conditional jump in svc_getreq_common based on the uninitialised memory and this caused a general protection fault in rpc.statd on an older version of glibc but this code has not changed since that version. Following is the valgrind warning. ==26802== Conditional jump or move depends on uninitialised value(s) ==26802== at 0x5343A25: svc_getreq_common (in /lib64/libc-2.5.so) ==26802== by 0x534357B: svc_getreqset (in /lib64/libc-2.5.so) ==26802== by 0x10DE1F: ???
