Hmmmmm, you are correct. I was sure that you were nuts, but on
-current the following program returns no error at all... Telnet
shows the same behavior. This is clearly wrong.
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <err.h>
int main(void)
{
int fd;
struct in_addr addr;
struct sockaddr_in sa;
int flags;
fd = socket(PF_INET, SOCK_STREAM, 0);
inet_aton("1.2.3.4", &addr);
sa.sin_len = sizeof(sa);
sa.sin_family = AF_INET;
sa.sin_port = htons(1234);
memcpy(&sa.sin_addr, &addr, sizeof(addr));
if (connect(fd, (struct sockaddr *) &sa, sizeof(sa)))
err(1, "connect");
exit(0);
}
