RH-Commit: [4/7] a8ec1996262b2bb657b8fe2e72c9045faee0a64c (JurajMarcin/centos-src-qemu-kvm)

Commit aec21d3175 (qapi: Add InetSocketAddress member keep-alive)
|
|
introduces the keep-alive flag, which enables the SO_KEEPALIVE socket
|
|
option, but only on client-side sockets. However, this option is also
|
|
useful for server-side sockets, so they can check if a client is still
|
|
reachable or drop the connection otherwise.
|
|
|
|
This patch enables the SO_KEEPALIVE socket option on passive server-side
|
|
sockets if the keep-alive flag is enabled. This socket option is then
|
|
inherited by active server-side sockets communicating with connected
|
|
clients.
