From 1f4bf0fb0fbcecd6de92047f6f68bf822af67a09 Mon Sep 17 00:00:00 2001 From: Stefan Metzmacher Date: Wed, 28 Sep 2011 08:23:24 +0200 Subject: s4:libcli/smb2: ignore SMB2_OP_CANCEL responses If there're a problem with signing or the session doesn't exists any more the server responses with a failure, instead of not sending a response. For now we ignore the reponse, as there's not much we could do with it and it's not likely that we generate bad requests, which trigger that behavior, except for testing. metze --- source4/libcli/smb2/transport.c | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/source4/libcli/smb2/transport.c b/source4/libcli/smb2/transport.c index a1653e3974..c17bbfde46 100644 --- a/source4/libcli/smb2/transport.c +++ b/source4/libcli/smb2/transport.c @@ -277,6 +277,16 @@ static NTSTATUS smb2_transport_finish_recv(void *private_data, DATA_BLOB blob) return smb2_handle_oplock_break(transport, &blob); } + if (opcode == SMB2_OP_CANCEL) { + /* + * ignore responses to cancel requests, + * this can happen if signing was wrong or + * we specified the wrong session id + */ + talloc_free(buffer); + return NT_STATUS_OK; + } + /* match the incoming request against the list of pending requests */ for (req=transport->pending_recv; req; req=req->next) { if (req->seqnum == seqnum) break; -- cgit
