Return the last socket error to user. Signed-off-by: Jukka Rissanen <jukka.rissanen@nordicsemi.no> (cherry picked from commit b864880)
If we try to connect to a port which no socket is listening to, we will get a packet with "ACK | RST" flags set. In this case the errno should be ECONNREFUSED instead of ETIMEDOUT like we used to return earlier. Signed-off-by: Jukka Rissanen <jukka.rissanen@nordicsemi.no> (cherry picked from commit ec4973d)
The writefds is typically set if there is an error while waiting for example the connect() to finish. So check if the user supplied the writefds and update it accordingly. Signed-off-by: Jukka Rissanen <jukka.rissanen@nordicsemi.no> (cherry picked from commit 5bf18e3)
This checks that if connect() timeouts, we check TCP pointer properly in select() and poll() in order to catch the situation. Signed-off-by: Jukka Rissanen <jukka.rissanen@nordicsemi.no> (cherry picked from commit b510073)
