Hi all, I have one question on the behavior of TCP/IPv4 sending using the MSG_ZEROCOPY flag, the kernel version is 4.19.18.
What happens if I close the sending socket immediately after performing a socket send() or sendmsg() call (called with the MSG_ZEROCOPY flag)? I.e. in this situation not all messages have been sent yet, however - as the socket is closed - it is no longer possible to retrieve the completion notification via the error channel. Is it fine for the user space program to free all outstanding messages after the socket close() has returned? Or is there anything else that has to be considered? Thanks for any help Best regards Mathias
