similar to: [PATCH] Matthew Fioravante now maintains VTPM

Since the vTPM implementations are being incorproated into Xen and possibly upstream Linux, I would like to see if this protocol change could be added before we have significant legacy implementations. If not, I still think it would be useful as either a v2 or negotiated protocol change. The current vTPM protocol is a copy of the network protocol. This was likely done for ease of implementation,

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 adds a new option for xen config files for directly mapping hardware io memory into a vm.

Hi community, there are some problems to start vTPM vtpm-stubdom following docs/misc/vtpm.txt. When I start vtpm-stbdom, the vtpmmgr-stubdom will print out: === ERROR[VTPM]: LoadKey failure: Unrecognized uuid! 69743ae0-9d4a-4ad6-9819-e602085b6792 ERROR[VTPM]: Failed to load key ERROR in vtpmmgr_LoadHashKey at vtpm_cmd_handler.c:78 code: TPM_BAD_PARAMETER. === I start vtpmmgr-stubdom with

What will follow soon are updates to vtpmd, vtpm_manager, xm, xl, mini-os, and new vtpm and vtpm manager stub domains. The first patch I''d like to submit upgrades vtpmd to version 0.7.4 This patch does the following: -add checks to configure to check for cmake (required by berlios 0.7.4) -removes all of the 0.5.1 patches -adds a single patch for 0.7.4 -cleans up the makefile, should

Hi, In Fedora 8 kernel source code, I could find tpmback.c in drivers/xen But where is tpmfront.c? in old distribution? thank for any help. superbobo _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi, I am following http://xenbits.xen.org/docs/unstable/misc/vtpm.txt, but I''m having some problems when I try to start vtpmmgr-stubdom I''m using Xen 4.3 on Ubuntu 12.04 and I have a physical TPM. The config file for vTPM manager is: kernel="/usr/local/lib/xen/boot/vtpmmgr-stubdom.gz" memory=16 disk=["file:/var/vtpmmgr-stubdom.img,hda,w"]

Ian, this one is special just for you. I''m sending it as an attachment because my email client will mangle it. This patch will remove the cmake dependency from xen prior to autoconf stubdom This patch applies ontop of [VTPM v7 3/8] vtpm/vtpmmgr and required libs to stubdom/Makefile You can apply it to your tree by doing the following: git rebase -i <VTPM v7 3/8 revision>

This patch ports 5 new applications to the stubdom makefile structure for inclusion into stubdom domains. While these are required for vtpm-stubdom and vtpmmgrdom they could be used with other stubdom applications. -libgmp 4.3.2 -openssl 1.0.0a -polarssl 0.12.1 -berlios tpm_emulator 0.6.1 -vtpm_manager (from the tools directory) Signed off by: Matthew Fioravante

The default make targets in the top level makefile set DESTDIR which gets applied when the stubdom makefile tries to do a make install within gmp to install libgmp.a to the cross root. Ian, do you want to apply this to your tree and commit the whole thing or would you prefer I roll out a fresh new patch set with all updates applied? Signed-off-by: Matthew Fioravante

I can get vtpm_manager to run if I delete /var/vtpm/VTPM. However, when I kill it with control-c, and try to run it again, I get: INFO[VTPM]: Starting VTPM.

So it looks like I was basing my patches off of this tree git://xenbits.xen.org/xen-unstable.git which is not actually xen-unstable. I rebased and reworked my patches off of the correct tree git://xenbits.xen.org/xen.git What follows are the vtpmd, vtpm_manager, and libxl patches. All of the mini-os patches apply cleanly to the latest xen so I won''t be resubmitting those unless you all

Hi, i am using Xen 3.2.0 and want to use the TPM in dom0. I have activated vtpm and everything runs fine in my domUs. The question is, how can I access the TPM in dom0? As far as I know vtpm_managerd exclusively locks /dev/tpm0. As soon as I start vtpm_managerd my own program cannot access the TPM anymore. Is there a vtpm instance for dom0 like the ones for the user domains? Thanks in advance
