Subject: Re: [PATCH] net: UDP repair mode for retrieving the send queue of
 corked UDP socket

From: Leşe Doru Călin <>
Date: Wed, 8 Apr 2020 23:59:54 +0300

> Hello everyone!
> In this year's edition of GSoC, there is a project idea for CRIU to add support
> for checkpoint/restore of cork-ed UDP sockets. But to add it, the kernel API needs
> to be extended.
> This is what this patch does. It adds UDP "repair mode" for UDP sockets in a similar
> approach to the TCP "repair mode", but only the send queue is necessary to be retrieved.
> So the patch extends the recv and setsockopt syscalls. Using UDP_REPAIR option in
> setsockopt, caller can set the socket in repair mode. If it is setted, the
> recv/recvfrom/recvmsg will receive the write queue and the destination of the data.
> As in the TCP mode, to change the repair mode requires the CAP_NET_ADMIN capability
> and to receive data the caller is obliged to use the MSG_PEEK flag.

Why do I feel like I've seen this patch several times before?
