I am new to kernel programming.
I need to write a kernel socket (TCP)module which listens to incoming requests (and also reply back). I downloaded the code from:
http://kernelnewbies.org/Simple_UDP_Server
and made changes
1) SOCK_DGRAM -> SOCK_STREAM and
2) IPPROTO_UDB -> IPPROTO_TCP
I run make on this file and obtain the .ko file. When i insmod the .ko file and observe the output of dmesg, i get a error message:
Error getting stream , sock_recvmsg error = -107
Can someone please let me know what could be the error?? Should i add more code or what changes do i need to make?
Also, i need the kernel API's for TCP sockets. Is it the same as user space API's?
Request anyone to please suggest the remedy.
Thanks in advance,
Ravi.
