Subject: [PATCH 39/41] VSOCK: do not disconnect socket when peer has shutdown
|
|
SEND only
|
|
|
|
The peer may be expecting a reply having sent a request and then done a
|
|
shutdown(SHUT_WR), so tearing down the whole socket at this point seems
|
|
wrong and breaks for me with a client which does a SHUT_WR.
|
|
|
|
Looking at other socket family's stream_recvmsg callbacks doing a shutdown
|
|
here does not seem to be the norm and removing it does not seem to have
|
|
had any adverse effects that I can see.
|
|
|
|
I'm using Stefan's RFC virtio transport patches, I'm unsure of the impact
|
|
on the vmci transport.
