When a message with zero length is sent to xenstore, the body of the message was not processed until the socket or ring had more data to read; this will cause deadlocks if the requestor is waiting on a response to continue.

Hi, I‘m trying to install vTPM based on Xen-4.2.2, linux-kernel 3.9.1 (Dom0) and TPM emulator. However, I cannot find the TPM backed driver in this version of Dom0 linux kernel. There is no CONFIG_XEN_TPMDEV_BACKEND in the kernel config file. The config file for Dom0 is attached. Maybe it provides some useful information. So, how to install a Xen TPM backend driver in the Dom0 linux-kernel.

This patch set adds XSM security labels to useful debugging output locations, and fixes some assumptions that all interrupts behaved like GSI interrupts (which had useful non-dynamic IDs). It also cleans up the policy build process and adds an example of how to use the user field in the security context.
