4b9b700002 tests: Add a test for qemu self announcements
We now expose qemu_announce_self through QMP and HMP.  Add a test
with some very basic packet validation (make sure we get a RARP).

544f6ea324 hmp: Add hmp_announce_self
Add an HMP command to trigger self annocements.
Unlike the QMP command (which takes a set of parameters), the HMP
command reuses the set of parameters used for migration.

906da88291 tests/tcg/xtensa: support configurations w/o vecbase
Configurations w/o vecbase may have vectors not grouped together and not
in fixed order. They may not always be grouped into single output
sections by assigning next offset to dot, as it may sometimes move dot
backwards and sometimes they may even belong to different memory region.
Don't group vectors into single output section. Instead put each vector
into its own section ant put it at its default virtual address.
Reserve 4KBytes from the default vectors base and put rest of the code
and data starting from there. Mark vectors sections as executable,
otherwise their contents is discarded. There may be as little as 16
bytes reserved for some vectors, load handler address into a0 and use
ret.n to jump there to make vector code fit into this 16 byte space.

3e6f45446b iotests: avoid broken pipe with certtool
When we run "certtool 2>&1 | head -1" the latter command is likely to
complete and exit before certtool has written everything it wants to
stderr. In at least the RHEL-7 gnutls 3.3.29 this causes certtool to
quit with broken pipe before it has finished writing the desired
output file to disk. This causes non-deterministic failures of the
iotest 233 because the certs are sometimes zero length files.
If certtool fails the "head -1" means we also lose any useful error
message it would have printed.

Thus this patch gets rid of the pipe and post-processes the output in a
more flexible & reliable manner.

b76806d4ec authz: delete existing ACL implementation
The 'qemu_acl' type was a previous non-QOM based attempt to provide an
authorization facility in QEMU. Because it is non-QOM based it cannot be
created via the command line and requires special monitor commands to
manipulate it.

The new QAuthZ subclasses provide a superset of the functionality in
qemu_acl, so the latter can now be deleted. The HMP 'acl_*' monitor
commands are converted to use the new QAuthZSimple data type instead
in order to provide temporary backwards compatibility.

8953caf3cd authz: add QAuthZPAM object type for authorizing using PAM
Add an authorization backend that talks to PAM to check whether the user
identity is allowed. This only uses the PAM account validation facility,
which is essentially just a check to see if the provided username is permitted
access. It doesn't use the authentication or session parts of PAM, since
that's dealt with by the relevant part of QEMU (eg VNC server).

Consider starting QEMU with a VNC server and telling it to use TLS with
x509 client certificates and configuring it to use an PAM to validate
the x509 distinguished name. In this example we're telling it to use PAM
for the QAuthZ impl with a service name of "qemu-vnc"

 $ qemu-system-x86_64 \
     -object tls-creds-x509,id=tls0,dir=/home/berrange/security/qemutls,\
             endpoint=server,verify-peer=yes \
     -object authz-pam,id=authz0,service=qemu-vnc \
     -vnc :1,tls-creds=tls0,tls-authz=authz0

This requires an /etc/pam/qemu-vnc file to be created with the auth
rules. A very simple file based whitelist can be setup using

  $ cat > /etc/pam/qemu-vnc <<EOF
  account         requisite       pam_listfile.so item=user sense=allow file=/etc/qemu/vnc.allow
  EOF

The /etc/qemu/vnc.allow file simply contains one username per line. Any
username not in the file is denied. The usernames in this example are
the x509 distinguished name from the client's x509 cert.

  $ cat > /etc/qemu/vnc.allow <<EOF
  CN=laptop.berrange.com,O=Berrange Home,L=London,ST=London,C=GB
  EOF

More interesting would be to configure PAM to use an LDAP backend, so
that the QEMU authorization check data can be centralized instead of
requiring each compute host to have file maintained.

The main limitation with this PAM module is that the rules apply to all
QEMU instances on the host. Setting up different rules per VM, would
require creating a separate PAM service name & config file for every
guest. An alternative approach for the future might be to not pass in
the plain username to PAM, but instead combine the VM name or UUID with
the username. This requires further consideration though.

55d869846d authz: add QAuthZListFile object type for a file access control list
Add a QAuthZListFile object type that implements the QAuthZ interface. This

initializing it from an external file, and optionally, automatically
reloading it whenever it changes.

To create an instance of this object via the QMP monitor, the syntax
used would be:

        "arguments": {
          "qom-type": "authz-list-file",

            "filename": "/etc/qemu/vnc.acl",
	    "refresh": true
          }
        }
      }

If "refresh" is "yes", inotify is used to monitor the file,
automatically reloading changes. If an error occurs during reloading,
all authorizations will fail until the file is next successfully
loaded.

The /etc/qemu/vnc.acl file would contain a JSON representation of a
QAuthZList object

    {
      "rules": [
         { "match": "fred", "policy": "allow", "format": "exact" },
         { "match": "bob", "policy": "allow", "format": "exact" },
         { "match": "danb", "policy": "deny", "format": "glob" },
         { "match": "dan*", "policy": "allow", "format": "exact" },
      ],
      "policy": "deny"
    }

This sets up an authorization rule that allows 'fred', 'bob' and anyone
whose name starts with 'dan', except for 'danb'. Everyone unmatched is
denied.

The object can be loaded on the comand line using

   -object authz-list-file,id=authz0,filename=/etc/qemu/vnc.acl,refresh=yes

c8c99887d1 authz: add QAuthZList object type for an access control list
Add a QAuthZList object type that implements the QAuthZ interface. This
built-in implementation maintains a trivial access control list with a
sequence of match rules and a final default policy. This replicates the
functionality currently provided by the qemu_acl module.

To create an instance of this object via the QMP monitor, the syntax
used would be:

  {
    "execute": "object-add",
    "arguments": {
      "qom-type": "authz-list",
      "id": "authz0",
      "props": {
        "rules": [
           { "match": "fred", "policy": "allow", "format": "exact" },
           { "match": "bob", "policy": "allow", "format": "exact" },
           { "match": "danb", "policy": "deny", "format": "glob" },
           { "match": "dan*", "policy": "allow", "format": "exact" },
        ],
        "policy": "deny"
      }
    }
  }

This sets up an authorization rule that allows 'fred', 'bob' and anyone
whose name starts with 'dan', except for 'danb'. Everyone unmatched is
denied.

It is not currently possible to create this via -object, since there is
no syntax supported to specify non-scalar properties for objects. This
is likely to be addressed by later support for using JSON with -object,
or an equivalent approach.

In any case the future "authz-listfile" object can be used from the
CLI and is likely a better choice, as it allows the ACL to be refreshed
automatically on change.

fb5c4ebc08 authz: add QAuthZSimple object type for easy whitelist auth checks
In many cases a single VM will just need to whitelist a single identity
as the allowed user of network services. This is especially the case for
TLS live migration (optionally with NBD storage) where we just need to
whitelist the x509 certificate distinguished name of the source QEMU
host.

Via QMP this can be configured with:

  {
    "execute": "object-add",
    "arguments": {
      "qom-type": "authz-simple",
      "id": "authz0",
      "props": {
        "identity": "fred"
      }
    }
  }

Or via the command line

  -object authz-simple,id=authz0,identity=fred

90e33dfec6 util: add helper APIs for dealing with inotify in portable manner
The inotify userspace API for reading events is quite horrible, so it is
useful to wrap it in a more friendly API to avoid duplicating code
across many users in QEMU. Wrapping it also allows introduction of a
platform portability layer, so that we can add impls for non-Linux based
equivalents in future.

bf30e8662c tests/Makefile.include: test all rounding modes of softfloat
We missed a bug in a recent patch as we were not testing all the
rounding modes for all operations. However enabling all rounding modes
for mulAdd does slow down the already slowest test and doesn't really
buy us much additional coverage so lets allow the default test flags
to be overridden.

Previously this was only supported for roundAndPackFloat64.

New support in round_canonical, round_to_int, float128_round_to_int,
roundAndPackFloat32, roundAndPackInt32, roundAndPackInt64,
roundAndPackUint64.  This does not include any of the floatx80 routines,
as we do not have users for that rounding mode there.
