The server detects reconnect by the (non-zero) value in PreviousSessionId of SMB2/SMB3 SessionSetup request, but this behavior regressed due to commit 166cea4dc3a4f66f020cfb9286225ecd228ab61d ("SMB2: Separate RawNTLMSSP authentication from SMB2_sess_setup") CC: Stable CC: Sachin Prabhu Signed-off-by: Steve French Reviewed-by: Ronnie Sahlberg Signed-off-by: Greg Kroah-Hartman --- diff --git a/fs/cifs/smb2pdu.c b/fs/cifs/smb2pdu.c index 49779d952cd5..70eeaa2925bb 100644 --- a/fs/cifs/smb2pdu.c +++ b/fs/cifs/smb2pdu.c @@ -1182,6 +1182,7 @@ SMB2_sess_setup(const unsigned int xid, struct cifs_ses *ses, sess_data->ses = ses; sess_data->buf0_type = CIFS_NO_BUFFER; sess_data->nls_cp = (struct nls_table *) nls_cp; + sess_data->previous_session = ses->Suid; while (sess_data->func) sess_data->func(sess_data);
