[Xen-devel] Fix for unassigned errno in xenstored_core.c
Dear all, In certain cases, when a client doesn''t have enough permissions, the errno variable is not set in xenstored_core.c before its value is reported back. As a result, the client can learn about the errno of the last failed request to xenstored (which could have come from another client). (An unintended information channel! :-) Attached is a patch that I believe fixes the problem. Also included are a couple of test cases that demonstrate the problem. Cheers, Magnus _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
