This uses iconv to convert glyphs from the specified VGA font encoding to unicode, and makes use of cchar_t instead of chtype when using ncursesw, which allows to store all wide char as well as the WACS values.

2019-03-11chardev: add support for authorization for TLS clientsDaniel P. Berrange1-2/+8
Currently any client which can complete the TLS handshake is able to use a chardev server. The server admin can turn on the 'verify-peer' option for the x509 creds to require the client to provide a x509 certificate. This means the client will have to acquire a certificate from the CA before they are permitted to use the chardev server. This is still a fairly low bar. This adds a 'tls-authz=OBJECT-ID' option to the socket chardev backend which takes the ID of a previously added 'QAuthZ' object instance. This will be used to validate the client's x509 distinguished name. Clients failing the check will not be permitted to use the chardev server. For example to setup authorization that only allows connection from a client whose x509 certificate distinguished name contains 'CN=fred', you would use: $QEMU -object tls-creds-x509,id=tls0,dir=/home/berrange/qemutls,\ endpoint=server,verify-peer=yes \ -object authz-simple,id=authz0,identity=CN=laptop.example.com,,\ O=Example Org,,L=London,,ST=London,,C=GB \ -chardev socket,host=127.0.0.1,port=9000,server,\ tls-creds=tls0,tls-authz=authz0 \ ...other qemu args...

2019-03-11vnc: allow specifying a custom authorization object nameDaniel P. Berrange1-10/+25
The VNC server has historically had support for ACLs to check both the SASL username and the TLS x509 distinguished name. The VNC server was responsible for creating the initial ACL, and the client app was then responsible for populating it with rules using the HMP 'acl_add' command. This is not satisfactory for a variety of reasons. There is no way to populate the ACLs from the command line, users are forced to use the HMP. With multiple network services all supporting TLS and ACLs now, it is desirable to be able to define a single ACL that is referenced by all services. To address these limitations, two new options are added to the VNC server CLI. The 'tls-authz' option takes the ID of a QAuthZ object to use for checking TLS x509 distinguished names, and the 'sasl-authz' option takes the ID of another object to use for checking SASL usernames. In this example, we setup two authorization rules. The first allows any client with a certificate issued by the 'RedHat' organization in the 'London' locality. The second ACL allows clients with either the 'joe@REDHAT.COM' or 'fred@REDHAT.COM' kerberos usernames. Both checks must pass for the user to be allowed. $QEMU -object tls-creds-x509,id=tls0,dir=/home/berrange/qemutls,\ endpoint=server,verify-peer=yes \ -object authz-simple,id=authz0,policy=deny,\ rules.0.match=O=RedHat,,L=London,rules.0.policy=allow \ -object authz-simple,id=authz1,policy=deny,\ rules.0.match=fred@REDHAT.COM,rules.0.policy=allow \ rules.0.match=joe@REDHAT.COM,rules.0.policy=allow \ -vnc 0.0.0.0:1,tls-creds=tls0,tls-authz=authz0, sasl,sasl-authz=authz1 \ ...other QEMU args...

2019-02-26authz: add QAuthZPAM object type for authorizing using PAMDaniel P. Berrange1-0/+35
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.

2019-02-26authz: add QAuthZListFile object type for a file access control listDaniel P. Berrangé1-0/+46
Add a QAuthZListFile object type that implements the QAuthZ interface. This built-in implementation is a proxy around the QAuthZList object type, 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: { "execute": "object-add", "arguments": { "qom-type": "authz-list-file", "id": "authz0", "props": { "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 Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> Tested-by: Philippe Mathieu-Daudé <philmd@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Signed-off-by: Daniel P.

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.

A QMP monitor is also exposed as a Spice port, this allows the remote client fuller qemu control and state handling. - doesn't handle VC set_echo() - this doesn't seem a strong requirement, very few front-end use it - spice options can be tweaked with other -spice arguments - Windows support shouldn't be hard to do, but will probably use a TCP port instead - we may want to watch the child process to quit automatically if it crashed Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Tested-by: Victor Toso <victortoso@redhat.com> Message-id: 20190221110703.5775-12-marcandre.lureau@redhat.com [ kraxel: squash incremental fix ] Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

The default cache-clean-interval is set to 10 minutes, in order to lower the overhead of the qcow2 caches (before the default was 0, i.e. disabled). * For non-Linux platforms the default is kept at 0, because cache-clean-interval is not supported there yet.

2018-10-01qcow2: Increase the default upper limit on the L2 cache sizeLeonid Bloch1-3/+3
The upper limit on the L2 cache size is increased from 1 MB to 32 MB on Linux platforms, and to 8 MB on other platforms (this difference is caused by the ability to set intervals for cache cleaning on Linux platforms only). This is done in order to allow default full coverage with the L2 cache for images of up to 256 GB in size (was 8 GB). Note, that only the needed amount to cover the full image is allocated. The value which is changed here is just the upper limit on the L2 cache size, beyond which it will not grow, even if the size of the image will require it to.

2018-10-01qcow2: Assign the L2 cache relatively to the image sizeLeonid Bloch1-3/+3
Sufficient L2 cache can noticeably improve the performance when using large images with frequent I/O. Previously, unless 'cache-size' was specified and was large enough, the L2 cache was set to a certain size without taking the virtual image size into account. Now, the L2 cache assignment is aware of the virtual size of the image, and will cover the entire image, unless the cache size needed for that is larger than a certain maximum. This maximum is set to 1 MB by default (enough to cover an 8 GB image with the default cluster size) but can be increased or decreased using the 'l2-cache-size' option. This option was previously documented as the *maximum* L2 cache size, and this patch makes it behave as such, instead of as a constant size. Also, the existing option 'cache-size' can limit the sum of both L2 and refcount caches, as previously.

The -drive options cyls, heads, secs and trans were deprecated in QEMU 2.10. It's time to remove them. hd-geo-test tested both the old version with geometry options in -drive and the new one with -device. Therefore the code using -drive doesn't have to be replaced there, we just need to remove the -drive test cases. This in turn allows some simplification of the code.

2018-08-10hostmem-file: add the 'pmem' optionJunyan He1-0/+7
When QEMU emulates vNVDIMM labels and migrates vNVDIMM devices, it needs to know whether the backend storage is a real persistent memory, in order to decide whether special operations should be performed to ensure the data persistence. This boolean option 'pmem' allows users to specify whether the backend storage of memory-backend-file is a real persistent memory. If 'pmem=on', QEMU will set the flag RAM_PMEM in the RAM block of the corresponding memory region. If 'pmem' is set while lack of libpmem support, a error is generated.
