2013-03-13chardev: add support for qapi-based chardev initializationGerd Hoffmann2-0/+45
This patch add support for a new way to initialize chardev devices. Instead of calling a initialization function with a QemuOpts we will now create a (qapi) ChardevBackend, optionally call a function to fill ChardevBackend from QemuOpts, then go create the chardev using the new qapi code path which is also used by chardev-add.

2013-03-12Add search path support for qemu data files.Gerd Hoffmann2-13/+24
This patch allows to specify multiple directories where qemu should look for data files. To implement that the behavior of the -L switch is slightly different now: Instead of replacing the data directory the path specified will be appended to the data directory list. So when specifiying -L multiple times all directories specified will be checked, in the order they are specified on the command line, instead of just the last one. Additionally the default paths are always appended to the directory data list. This allows to specify a incomplete directory (such as the seabios out/ directory) via -L. Anything not found there will be loaded from the default paths, so you don't have to create a symlink farm for all the rom blobs. For trouble-shooting a tracepoint has been added, logging which blob has been loaded from which location.

2013-03-12Add support for cancelling of a TPM commandStefan Berger3-16/+171
This patch adds support for cancelling an executing TPM command. In Linux for example a user can cancel a command through the TPM's sysfs 'cancel' entry using echo "1" > /sysfs/class/misc/tpm0/device/cancel This patch propagates the cancellation of a command inside a VM to the host TPM's sysfs entry. It also uses the possibility to cancel the command before QEMU VM shutdown or reboot, which helps in preventing QEMU from hanging while waiting for the completion of the command. To relieve higher layers or users from having to determine the TPM's cancel sysfs entry, the driver searches for the entry in well known locations.

2013-03-12Add a TPM Passthrough backend driver implementationStefan Berger9-1/+599
This patch is based of off version 9 of Stefan Berger's patch series "QEMU Trusted Platform Module (TPM) integration" and adds a new backend driver for it. This patch adds a passthrough backend driver for passing commands sent to the emulated TPM device directly to a TPM device opened on the host machine. Thus it is possible to use a hardware TPM device in a system running on QEMU, providing the ability to access a TPM in a special state (e.g. after a Trusted Boot). This functionality is being used in the acTvSM Trusted Virtualization Platform which is available on [1]. Usage example: qemu-system-x86_64 -tpmdev passthrough,id=tpm0,path=/dev/tpm0 \ -device tpm-tis,tpmdev=tpm0 \ -cdrom test.iso -boot d Some notes about the host TPM: The TPM needs to be enabled and activated. If that's not the case one has to go through the BIOS/UEFI and enable and activate that TPM for TPM commands to work as expected. It may be necessary to boot the kernel using tpm_tis.force=1 in the boot command line or 'modprobe tpm_tis force=1' in case of using it as a module.

2013-03-12Add TPM (frontend) hardware interface (TPM TIS) to QEMUStefan Berger1-0/+859
This patch adds the main code of the TPM frontend driver, the TPM TIS interface, to QEMU. The code is largely based on the previous implementation for Xen but has been significantly extended to meet the standard's requirements, such as the support for changing of localities and all the functionality of the available flags. Communication with the backend (i.e., for Xen or the libtpms-based one) is cleanly separated through an interface which the backend driver needs to implement. Whenever the frontend has collected a complete packet, it will submit a task to the backend, which then starts processing the command. Once the result has been returned, the backend invokes a callback function (tpm_tis_receive_cb()). Testing the proper functioning of the different flags and localities cannot be done from user space when running in Linux for example, since access to the address space of the TPM TIS interface is not possible. Also the Linux driver itself does not exercise all functionality. So, for testing there is a fairly extensive test suite as part of the SeaBIOS patches since from within the BIOS one can have full access to all the TPM's registers.

2013-03-12Support for TPM command line optionsStefan Berger14-0/+776
This patch adds support for TPM command line options. The command line options supported here are ./qemu-... -tpmdev passthrough,path=<path to TPM device>,id=<id> -device tpm-tis,tpmdev=<id>,id=<other id> and ./qemu-... -tpmdev help where the latter works similar to -soundhw help and shows a list of available TPM backends (for example 'passthrough'). Using the type parameter, the backend is chosen, i.e., 'passthrough' for the passthrough driver. The interpretation of the other parameters along with determining whether enough parameters were provided is pushed into the backend driver, which needs to implement the interface function 'create' and return a TPMDriverOpts structure if the VM can be started or 'NULL' if not enough or bad parameters were provided. Monitor support for 'info tpm' has been added. It for example prints the following: (qemu) info tpm TPM devices: tpm0: model=tpm-tis \ tpm0: type=passthrough,path=/dev/tpm0,cancel-path=/sys/devices/pnp0/00:09/cancel Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Reviewed-by: Corey Bryant <coreyb@linux.vnet.ibm.com> Reviewed-by: Joel Schopp <jschopp@linux.vnet.ibm.com> Message-id: 1361987275-26289-2-git-send-email-stefanb@linux.vnet.ibm.com Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2013-03-11qemu-ga: use key-value store to avoid recycling fd handles after restartMichael Roth3-6/+204
Hosts hold on to handles provided by guest-file-open for periods that can span beyond the life of the qemu-ga process that issued them. Since these are issued starting from 0 on every restart, we run the risk of issuing duplicate handles after restarts/reboots. As a result, users with a stale copy of these handles may end up reading/writing corrupted data due to their existing handles effectively being re-assigned to an unexpected file or offset. We unfortunately do not issue handles as strings, but as integers, so a solution such as using UUIDs can't be implemented without introducing a new interface. As a workaround, we fix this by implementing a persistent key-value store that will be used to track the value of the last handle that was issued across restarts/reboots to avoid issuing duplicates. The store is automatically written to the same directory we currently set via --statedir to track fsfreeze state, and so should be applicable for stable releases where this flag is supported. A follow-up can use this same store for handling fsfreeze state, but that change is cosmetic and left out for now.
