      conf: Add support for choosing emulation of a TPM 2.0 · 8737578d
      由 Stefan Berger 提交于 
      This patch extends the TPM's device XML with TPM 2.0 support. This only works
for the emulator type backend and looks as follows:

    <tpm model='tpm-tis'>
      <backend type='emulator' version='2.0'/>
    </tpm>

The swtpm process now has --tpm2 as an additional parameter:

system_u:system_r:svirt_t:s0:c597,c632 tss 18477 11.8  0.0 28364  3868 ?        Rs   11:13  13:50 /usr/bin/swtpm socket --daemon --ctrl type=unixio,path=/var/run/libvirt/qemu/swtpm/testvm-swtpm.sock,mode=0660 --tpmstate dir=/var/lib/libvirt/swtpm/testvm/tpm2,mode=0640 --log file=/var/log/swtpm/libvirt/qemu/testvm-swtpm.log --tpm2 --pid file=/var/run/libvirt/qemu/swtpm/testvm-swtpm.pid

The version of the TPM can be changed and the state of the TPM is preserved.

      qemu: Extend QEMU with external TPM support · 2a606b86
      由 Stefan Berger 提交于 
      Implement functions for managing the storage of the external swtpm as well
as starting and stopping it. Also implement functions to use swtpm_setup,
which simulates the manufacturing of a TPM, which includes creation of
certificates for the device.

Further, the external TPM needs storage on the host that we need to set
up before it can be run. We can clean up the host once the domain is
undefined.

This patch also implements a small layer for external device support that
calls into the TPM device layer if a domain has an attached TPM. This is
the layer we will wire up later on.

      conf: Add support for external swtpm TPM emulator to domain XML · 33af0b2b
      由 Stefan Berger 提交于 
      This patch adds support for an external swtpm TPM emulator. The XML for
this type of TPM looks as follows:

 <tpm model='tpm-tis'>
   <backend type='emulator'/>
 </tpm>

The XML will currently only define a TPM 1.2.

Extend the documentation.

Add a test case testing the XML parser and formatter.

      qemu: Fix double free in qemuDomainSecretAESClear · 228ae709
      由 John Ferlan 提交于 
      Commit id 02b031a4 added a secondary path from which the
incoming @secinfo would not be free'd until the private
data was freed in qemuDomainStorageSourcePrivateDispose.

However, by doing this the original intention to free
@*secinfo afterwards is lost and thus the pass by value
of the secinfo->s.aes (or secinfo->s.plain for its method)
results in not keeping the NULL setting in the various
secret.{username|iv|ciphertext} fields upon return to
qemuDomainSecretInfoClear and eventually will result in
a double free at domain destroy:

    raise ()
    abort ()
    __libc_message ()
    malloc_printerr ()
    _int_free ()
    virFree
    qemuDomainSecretAESClear
    qemuDomainSecretInfoClear
    qemuDomainSecretInfoFree
    qemuDomainStorageSourcePrivateDispose
    virObjectUnref
    virStorageSourceClear
    virStorageSourceFree
    virDomainDiskDefFree
    virDomainDefFree
    virDomainObjRemoveTransientDef
    qemuProcessStop
    qemuDomainDestroyFlags
    virDomainDestroy

      all: Replace virGetLastError with virGetLastErrorCode where we can · 2b6667ab
      由 ramyelkest 提交于 
      Replace instances where we previously called virGetLastError just to
either get the code or to check if an error exists with
virGetLastErrorCode to avoid a validity pre-check.
