Hi,
I just created a test program, which creates a socket and tries to
connect to server port. But no server process is created. In this case
the connection fails. If I run this code in a loop, after some time I
am getting crash (attached below). I belive there must be some patch
to fix this issue. can anyone let me know the link of it?
I am running this on my embedded PXA255 target and linux kernel
version is 2.6.26.
sock_fd = socket(AF_INET, SOCK_STREAM, 0);
serv_addr.sin_family = AF_INET;
serv_addr.sin_addr.s_addr = htonl(0x7F000001);
serv_addr.sin_port = htons(41001);
for (;;)
{
err = connect(sock_fd, (struct sockaddr *)&serv_addr, sizeof(serv_addr));
if (err == -1 && errno != EINPROGRESS)
{
fprintf(stderr, "Connect failed\n");
return -1;
}
}
unable to cInternal error: Oops: f3 [#1]
