rdcp's Issues
Small files (962 bytes) get transferred as 0 byte files
If I transfer a 962 byte file, the file is created on the server, but it is 0 size:
ls -l foo
-rwxr-xr-x 1 razeh btt 962 Apr 1 15:39 foo*
ls -l foo
-rw------- 1 razeh btt 0 Apr 1 15:40 foo
The log on the server is:

rdma_bind_addr successful

cma_event type RDMA_CM_EVENT_CONNECT_REQUEST cma_id 0x2aaab4000a30 (remote)

No error code returned on the client when copying non-existent files
If you copy a file that doesn't exist, the following sequence happens:
cm_thread starts
the client connects to the server
rdcp_run_client runs, fails, disconnects and sleeps(1)
cm_thread exits with a return status of 0
From a scripting point of view it makes it a bit more difficult to tell if things went wrong.
Double free in rdcp_free_buffers of cb->start_buf
There is a double free in rdxcp_free_buffers of cb-start_buf.
It is freed at line 612 and again at line 631.
order of arguments to compiler cause an error on some distros
executing make generated the command which fails:
cc -Wall -libverbs -lrdmacm -lpthread rdcp.c -o rdcp
moving rdcp.c as first argument seems to work
cc rdcp.c -Wall -libverbs -lrdmacm -lpthread -o rdcp
if file size is very low then transfer stat shows negative value
example
[root@l-csi-demo-05 ~]# rdcp /tmp/mlxfwup.cache 11.7.159.6:/tmp/1.1
mlxfwup.cache 100% 0MB -2147483648MB/s 00:00 ETA
standard output
can you add standard input, standard output with named pipe source/destination
Extra ; around line rdcp.c:611
There is an extra semicolon around line 611 in rdcp.c:
`static void rdcp_free_buffers(struct rdcp_cb *cb)
{
int i;
VERBOSE_LOG(3, "rdcp_free_buffers called on cb %p\n", cb);
if (cb->start_buf); // THIS SEMICOLON DOESN'T MATCH THE INDENTATION
free(cb->start_buf);
if (cb->rdma_mr)
