[merge branch] msg_layer fails when empty newline at end of /etc/popcorn/nodes config #86

Closed bxatnarf closed 4 years ago

bxatnarf commented 4 years ago

When I insmod the msg_layer with the following configuration file (note: this file ends with \n\n)

10.4.4.100
10.4.4.101

insmod doe not return and instead shows the following:

popcorn@x86:~$ sudo insmod msg_socket.ko 
insmod: ERROR: could not insert module msg_socket.ko: Invalid parameters

Meanwhile the following errors are printed to the kernel log
