UDP linger timeout will be wrongly converted to UINT_MAX by _SO_TIMEOUT() when it is set to 0,
net/socket/socket.h:
|
| # define _SO_TIMEOUT(t) ((t) ? (t) * MSEC_PER_DSEC : UINT_MAX)
net/udp/udp_close.c:
|
| if (_SO_GETOPT(conn->sconn.s_options, SO_LINGER))
| {
| timeout = _SO_TIMEOUT(conn->sconn.s_linger);
| }
this change will correct this behavior, if the linger is set to 0, the timeout value should be 0
