Package: libc6 Version: 2.13-36 Severity: normal Dear Maintainer,
when calling getaddrinfo(), valgrind detects: ==7051== Syscall param socketcall.connect(serv_addr.sin6_addr) points to uninitialised byte(s) ==7051== at 0x362E6DB780: __connect_nocancel (syscall-template.S:82) ==7051== by 0x362E6B9307: getaddrinfo (getaddrinfo.c:2279) ==7051== by 0x4006A3: main (x.c:17) ==7051== Address 0x7feffff10 is on thread 1's stack ==7051== Uninitialised value was created by a stack allocation ==7051== at 0x362E6B8FD0: getaddrinfo (getaddrinfo.c:2092) Here is the short C source to reproduce the problem (gcc -g x.c -o x): #include <stdio.h> #include <string.h> #include <sys/types.h> #include <sys/socket.h> #include <netdb.h> void main(void) { struct addrinfo *addrinfo = NULL; struct addrinfo hints; memset(&hints,0,sizeof(hints)); hints.ai_family = AF_UNSPEC; hints.ai_socktype = SOCK_STREAM; hints.ai_flags = AI_NUMERICSERV; if (getaddrinfo("www.example.com", "80", &hints, &addrinfo) == 0) freeaddrinfo(addrinfo); } This problem is pretty new, maybe introduced by fixing bug #690021.
