How to use non blocking operation

Open afett opened this issue 7 years ago • 2 comments

The icmpv6 socket ist neither made nonblocking via O_NONBLOCK nor is recvfrom(2) passed MSG_DONTWAIT.

One cloud of course make the the fd nonblocking after retrieving it via ndp_get_eventfd() and check -EAGAIN on ndp_callall_eventfd_handler(). Is that how it's supposed to work?

I saw the NetworkManager code ignore the return of ndp_callall_eventfd_handler() altogether.
