Subject: Add sys_cxnet() handler for network-related syscalls and handler stubs for a number... 
X-Git-Url: https://git.corax.cc/?a=commitdiff_plain;h=9a8f8713dfb6859000b84ca9b33a92bc94dc936e;p=corax

Add sys_cxnet() handler for network-related syscalls and handler stubs for a number of sub-syscalls:
 - sys_socket()
 - sys_close()
 - sys_sendto()
 - sys_recvfrom()
 - sys_connect()
 - sys_listen()
 - sys_accept()
 - sys_setsockopt()
 - sys_getsockopt()
 - sys_shutdown()
 - sys_select()
 - sys_poll()
