Quan Xu 28b3ca49b0 stubdom: fix vtpm build failure due to duplicated typedefs.
Typedefs are duplicated in stubdom/vtpmmgr/tcg.h and supported compilers
do not cope with current staging branch.

Wei Liu ed6dd1db77 stubdom: fix make clean and distclean on a freshly cloned tree
Clean and distclean targets need not depend on existence of the mini-os
tree. Don't check for mini-os and don't try to blindly include
mini-os's Config.mk when doing clean and distclean.

Note that one subtle issue is that $(XEN_ROOT)/Config.mk tries to
include $(XEN_ROOT)/config/$(XEN_OS).mk. In stubdom's case XEN_OS is
"MiniOS". Then $(XEN_ROOT)/config/MiniOS.mk tries to include mini-os's
Config.mk.

Since clean and distclean don't enforce existence of mini-os tree, don't
include $(XEN_ROOT)/Config.mk to avoid getting error due to the
aforementioned issue.

Stefano Stabellini e6fa63d6cf pvgrub: ignore NUL
When using pvgrub in graphical mode with vnc, the grub timeout doesn't
work: the countdown doesn't even start. With a serial terminal the
problem doesn't occur and the countdown works as expected.

It turns out that the problem is that when using a graphical terminal,
checkkey () returns 0 instead of -1 when there is no activity on the
mouse or keyboard. As a consequence grub thinks that the user typed
something and interrupts the count down.

To fix the issue simply ignore keystrokes returning 0, that is the NUL
character anyway. Add a patch to grub.patches to do that.

Olaf Hering 2c96ecb1a4 Use configure --libexecdir=BASEDIR to set LIBEXEC
The current usage of LIBEXEC is bogus. It describes the directory for
private xen executables. Other places create their own, similar
libexecdir path as $prefix/lib/xen/*.

Additional two other variables are used to describe similar paths:
PRIVATE_BINDIR and PRIVATE_PREFIX

The autoconf documentation refers to libexec as a directory for
executables and stuff which is called by other programs, not by the
user.

Adjust all places that want libexecdir as a target path. LIBEXEC refers
now to the base directory. Three convenience variables are used to refer
to paths to private binaries, libs and include files.

In the systemd files LIBEXEC_BIN is substituted, so this variable has to
be present in autoconf. All other variables are expanded in Paths.mk
because they are only used in Makefiles.

Most users of LIBEXEC are updated to use LIBEXEC_BIN because that is
what they want.

Users of PRIVATE_BINDIR are updated to use LIBEXEC_BIN because that is
what they want. PRIVATE_BINDIR and PRIVATE_PREFIX usage is removed by
this patch, in favour of LIBXEC_BIN and LIBEXEC

An internal libxl function was removed. A single helper to retrieve
LIBEXEC_BIN remains.

As suggested by the autoconf documentation, configure appends the
package name to LIBEXEC to make sure the provided directory really
refers to xen. This makes sure "make uninstall" preserves the real
libexecdir.

Because there is not currently a method for the vTPM Manager to obtain a
build hash of a vTPM, use the hash of the vTPM's XSM label as a
substitute.  This allows the vTPM Manager to distinguish between vTPMs
intended to be paired with a hardware domain kernel (which cannot use
pv-grub) and vTPMs which are paired with a pv-grub domain and therefore
contain reliable measurements of the guest kernel in PCRs 4 and 5.

This adds an optional argument --vtpm-label=<label> to the pv-grub

pv-grub domain and the backend of this device must have the given XSM
label (which may start with a * to indicate a wildcard).  Verifying the
label of the vTPM before sending measurements prevents a disaggregated
control domain that has access to xenstore but not to the guest domains
from causing the measurements performed by pv-grub to be discarded,
allowing the forgery of arbitrary kernel measurements in the TPM.

Daniel De Graaf c1fe4dcf3f vtpm: passthru requests to manager
When sending commands to a vTPM, commands with the VTPM_TAG_REQ2 tag are
passed directly to the TPM Manager since they are used in the management
interface to the TPM Manager. The VTPM_TAG_REQ tag is translated to
TPM_TAG_RQU_COMMAND to allow access to the physical TPM for certain
ordinals (PCRRead, Extend, and GetRandom).

Jason Andryuk 2c8a51eebe vtpmmgr: Convert TPM_Seal to use TPM_PCR_INFO_LONG
Infineon 1.2 TPMs fail TPM_Seal commands with TPM_BAD_PARAMETER when
PCRS are specified by a TPM_PCR_INFO structure.  Using a
TPM_PCR_INFO_LONG structure to specify PCRs succeeds, so update to use
that.  This also requires changes to use TPM_STORED_DATA12 for the
result.

Daniel De Graaf 5c3705c900 vtpmmgr: add TPM group support
This is a complete rewrite of the disk format and key hierarchy for the
TPM Manager. The new format supports multiple groups of vTPMs which
define the permitted configurations where a given vTPM's keys are
available, allowing upgrades of critical components while retaining the
secrecy of cryptographic keys.

New features of the TPM Manager are explained in the README and in the
definitions of the management commands in vtpm_manager.h.

New features for vTPMs:

1. The size of the state blob for a vTPM is expanded from 52 to 64
bytes in order to support future vTPMs using SHA-2/3 instead of SHA-1.

2. vTPMs can obtain a quote from the physical TPM with certain
resettable PCRs set to include information about the vTPM. This can be
used by a vTPM to provide evidence of its integrity, including the
secrecy of its EK, and for deep quotes.

Some additional changes made by this rewrite that may impact existing
users:

1. The value of WELLKNOWN_OWNER_AUTH was incorrect for the physical TPM;
the convention is to use all zero bits for well-known authentication
values, not all one bits.

2. Randomly generating the owner auth value for the physical TPM is no
longer supported, as it prevents later creation or certification of
AIKs (which the old manager did not support).

3. The vTPM Manager needs to be provisioned with a PCR composite and an
upgrade authority's public key before it will save data across boots.

The current implementation still has some limitations:
 * 5 valid system PCR selections per group
 * The vTPM Manager's disk can use at most 2MB of space
 * The vTPM domain's build hash is always set to null/zero

Most of the code relating to upgrade and rollback protection is
currently stubbed out, but future versions can add:
 * Support for using the TPM's monotonic counter to prevent rollback
   of vTPM data by taking and restoring disk snapshots
 * Masking the master disk encryption key using a value stored in the
   TPM's NVRAM so that revocation of old data is possible without
   relying on all previously authorized software stacks to respect the
   monotonic counter's value

GRUB usually always loads a whole disk track, even if that means going
beyond the end of the disk.  We thus have to gracefully return an error,
instead of letting the blkfront go panic.

This is purely a run of autogen.sh. I have not tried to build the result.

Ian Campbell b0f69ec5c7 tools: Make qemu-xen-traditional build optional.
Now that we have upstream qemu people may want to avoid building this extra
code.

There is a little bit of trickery in stubdom/configure.ac to ensure that the
ioemu stubdom is only built if qemu-traditional is enabled.

libxl will return an error if a caller tries to build a domain using
qemu-xen-traditional when this support was disabled at build time. Since
qemu-xen-traditional has been historically tightly bound to the Xen releases I
don't see any value in supporting "3rd party" provision of
qemu-xen-traditional.

We also do not want/need this on ARM therefore default is on for x86 and off
otherwise.
