With the kernel patch I recently submitted to list for review, tried the validate negotiate info fsctl (unsigned) on an smb3.0 mount against Windows 8.1 server and it failed, dropping the connection immediately. I repeated it with "sign" mount option and it worked fine. Trying the validate negotiate info fsctl against Samba though it worked fine with signing disabled implying that the server is not checking to make sure that that request is signed (the validate negotiate info fsctl is always supposed to be signed right?) -- Thanks, Steve -- To unsubscribe from this list: send the line "unsubscribe linux-cifs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
