Hi,
using getifaddrs i get the following valgrind warning :
==12949== Syscall param socketcall.sendto(msg) points to uninitialised byte(s)
==12949== at 0xE633ACC: sendto (socket.S:106)
==12949== by 0xE651F48: __netlink_sendreq (ifaddrs.c:112)
==12949== by 0xE6521E4: __netlink_request (ifaddrs.c:131)
==12949== by 0xE652AD8: getifaddrs (ifaddrs.c:390)
Indeed, ./glibc-2.3.6/sysdeps/unix/sysv/linux/ifaddrs.c:
92 struct
93 {
94 struct nlmsghdr nlh;
95 struct rtgenmsg g;
96 } req;
97 struct sockaddr_nl nladdr;
....
101
102 req.nlh.nlmsg_len = sizeof (req);
103 req.nlh.nlmsg_type = type;
104 req.nlh.nlmsg_flags = NLM_F_ROOT | NLM_F_MATCH | NLM_F_REQUEST;
105 req.nlh.nlmsg_pid = 0;
106 req.nlh.nlmsg_seq = h->seq;
107 req.g.rtgen_family = AF_UNSPEC;
....
112 return TEMP_FAILURE_RETRY (__sendto (h->fd, (void *) &req, sizeof (req),
0,
113 (struct sockaddr *) &nladdr,
114 sizeof (nladdr)));
some members are not initialized.
