From: "Daniel P. Berrange" <berrange@redhat.com> If a client had initiated a stream abort, it will have a call waiting for a reply in the queue. If more data continues to arrive on the stream, the abort command could mistakenly get signalled as complete. Remove the code from async data processing that looked for waiting calls. Add a sanity check to ensure no async call can ever be marked as needing a reply * src/rpc/virnetclient.c: Ensure async data packets can't trigger a reply --- src/rpc/virnetclient.c | 12 +++++++----- 1 files changed, 7 insertions(+), 5 deletions(-) diff --git a/src/rpc/virnetclient.c b/src/rpc/virnetclient.c index efaac88..055361d 100644 --- a/src/rpc/virnetclient.c +++ b/src/rpc/virnetclient.c @@ -627,11 +627,6 @@ static int virNetClientCallDispatchStream(virNetClientPtr client) case VIR_NET_CONTINUE: { if (virNetClientStreamQueuePacket(st, &client->msg) < 0) return -1; - - if (thecall && thecall->expectReply) { - VIR_DEBUG("Got sync data packet completion"); - thecall->mode = VIR_NET_CLIENT_MODE_COMPLETE; - } return 0; } @@ -1193,6 +1188,13 @@ int virNetClientSend(virNetClientPtr client, virNetClientCallPtr call; int ret = -1; + if (expectReply && + (msg->header.status == VIR_NET_CONTINUE)) { + virNetError(VIR_ERR_INTERNAL_ERROR, "%s", + _("Attempt to send an asynchronous message with a synchronous reply")); + return -1; + } + if (VIR_ALLOC(call) < 0) { virReportOOMError(); return -1; -- 1.7.6
