1:33 a.m.
When connecting to a remote libvirtd, or hypervisor that requires
authentication we have callbacks which can be used to prompt for
various credentials. This is tedious if you are looking to automate
stuff though. While we could let each application implement a
custom auth callback for fetching credentials from a config file,
it is nicer if we provide this ability directly in libvirt, so that
all apps can benefit from it.
So this series introduces a new config file in which authentication
credentials can be placed. It supports setting multiple sets of
credentials, of varying types in one file. I use the '.ini' config
file syntax, since this makes it easy to reuse the same config file
in virt-viewer & similar apps to store VNC / SPICE credentials.
To find the config file we check for each of
- Path from LIBVIRT_AUTH_FILE env var
- Query param 'authfile=PATH' in the URI params
- /etc/libvirt/auth.conf
- $HOME/.libvirt/auth.conf
if no config file is present, everything should carry on as normal.
If the config is present, then it is consulted to fill in credentials
first. Only if there are still missing credentials, will the auth
callbacks then be invoked.
See the docs in patch 12 of this series for the config file
syntax examples.
This is supported for all drivers that do auth, remote, esx,
xenapi, hyperv and phyp, though I have only tested it with the
remote driver. I would appreciate someone giving it a go with
the other drivers.
The first 7 patches are actually all related to the viruri.[ch]
file, expanding its functionality & adding tests. This is to
make sure the auth config patches can have easy access to the
query params.
The last 7 patches are related to the auth config file support
again including tests

It's not neccessary to be out of memory error, perhaps
VIR_DEBUG with a msg is better here.
libxml doesn't do any usefull error reporting here so we
can't find out what is actually wrong :-(

The cleanup label doesn't make any sense. Or it's for follow up
pacthes use? but it should be together with the follow up patch
if so.
I think it is preferrable to always have an explicit cleanup:
statement in this scenario, rather than relying on fallthrough.
It avoids future code additionals introducing cleanup bugs.
Regards,
Daniel

New subject: [libvirt] [PATCH 05/14] Use a libvirt custom struct for virURIPtr
From: "Daniel P. Berrange" <berrange(a)redhat.com>
Instead of just typedef'ing the xmlURIPtr struct for virURIPtr,
use a custom libvirt struct. This allows us to fix various
problems with libxml2. This initially just fixes the query vs
query_raw handling problems.

New subject: [libvirt] [PATCH 05/14] Use a libvirt custom struct for virURIPtr
On 2012年03月21日 01:33, Daniel P. Berrange wrote:
From: "Daniel P. Berrange"<berrange(a)redhat.com>
Instead of just typedef'ing the xmlURIPtr struct for virURIPtr,
use a custom libvirt struct. This allows us to fix various
problems with libxml2. This initially just fixes the query vs
query_raw handling problems.

This patch does not round-trip queries that include % escapes. The old
qparamtest.c tried to roundtrip foo=one%20two (the literal value of 'one
two' when not URI-encoded); but now virURIFormat re-escapes the % into
one%2520two. I caught this with my attempt to enhance viruritest to the
same level as qparamtest, but didn't want to spend any further time in
fixing viruri.c.

New subject: [libvirt] [PATCH 07/14] Convert drivers over to use virURIPtr for query params

From: "Daniel P. Berrange"<berrange(a)redhat.com>
Convert drivers currently using the qparams APIs, to instead
use the virURIPtr query parameters directly.
* src/esx/esx_util.c, src/hyperv/hyperv_util.c,

use of qparams
* src/util/qparams.h, src/util/qparams.c: Delete

New subject: [libvirt] [PATCH 08/14] Add a virKeyfilePtr object for parsing '.ini' files
From: "Daniel P. Berrange" <berrange(a)redhat.com>
The '.ini' file format is a useful alternative to the existing
config file style, when you need to have config files which
are hashes of hashes. The 'virKeyFilePtr' object provides a
way to parse these file types.
* src/Makefile.am, src/util/virkeyfile.c,
src/util/virkeyfile.h: Add .ini file parser
* tests/Makefile.am, tests/virkeyfiletest.c: Test
basic parsing capabilities

New subject: [libvirt] [PATCH 08/14] Add a virKeyfilePtr object for parsing '.ini' files

From: "Daniel P. Berrange"<berrange(a)redhat.com>
The '.ini' file format is a useful alternative to the existing
config file style, when you need to have config files which
are hashes of hashes. The 'virKeyFilePtr' object provides a
way to parse these file types.

*path will be NULL if the last choice of authfile (e.g.
/etc/libvirt/auth.conf) is not readable, while the function
will return 0.
Yes, that is correct behaviour. We only return '-1' upon some fatal
error. We return 0 if we successfully found a path, or if no path
exists. This is why we return the path in a out parameter, instead
of using the return value.

New subject: [libvirt] [PATCH 12/14] Add APIs for handling lookup of auth credentials from config file
From: "Daniel P. Berrange" <berrange(a)redhat.com>
This defines the format for the auth credential config file and
provides APIs to access the data. The config file contains
one or more named 'credential' sets
[credentials-$NAME]
credname1=value1
credname2=value2
eg
[credentials-test]
authname=fred
password=123456
[credentials-prod]
authname=bar
password=letmein
There are then one or more 'auth' sets which match services/hosts
and map to credential sets.
[auth-$SERVICE-$HOSTNAME]
credentials=$CREDENTIALS
eg
[auth-libvirt-test1.example.com]
credentials=test
[auth-libvirt-test2.example.com]
credentials=test
[auth-libvirt-demo3.example.com]
credentials=test
[auth-libvirt-prod1.example.com]
credentials=prod
* docs/auth.html.in: Document use of client auth config files
* src/Makefile.am, src/libvirt_private.syms,
src/util/virauthconfig.c, src/util/virauthconfig.h: Add
APIs for processing auth.conf file

configuration</a></h2>
+
+ <p>
+ When connecting to a remote hypervisor which requires authentication,
+most libvirt applications will prompt the user for the credentials. It is
+also possible to provide a client configuration file containing all the
+authentication credentials, avoiding any interaction. Libvirt will look
+for the authentication file using the following sequence:
+ </p>
+ <ol>
+ <li>The file path specified by the $LIBVIRT_AUTH_FILE environment
+ variable.</li>
+ <li>The file path specified by the "authfile=/some/file" URI
+ query parameter</li>
+ <li>The file $HOME/.libvirt/auth.conf</li>
+ <li>The file /etc/libvirt/auth.conf</li>
+ </ol>
+
+ <p>
+ The auth configuration file uses the traditional
<code>".ini"</code>
+ style syntax. There are two types of groups that can be present in
+ the config. First there are one or more <strong>credential</strong>
+ sets, which provide the actual authentication credentials. The keys
+ within the group may be:
+ </p>
+
+ <ul>
+ <li><code>username</code>: the user login name to act as. This
+ is relevant for ESX, Xen, HyperV and SSH, but probably not
+ the one you want to libvirtd with SASL.</li>
+ <li><code>authname</code>: the name to authorize as. This is
+ what is commonly required for libvirtd with SASL.</li>
+ <li><code>password</code>: the secret password</li>
+ <li><code>realm</code>: the domain realm for SASL, mostly
+ unused</li>
+ </ul>
+
+ <p>
+ Each set of credentials has a name, which is part of the group
+ entry name. Overall the syntax is
+ </p>
+
+ <pre>
+[credentials-$NAME]
+credname1=value1
+credname2=value2</pre>
+
+ <p>
+ For example, to define two sets of credentials used for production
+ and test machines, using libvirtd, and a further ESX server for dev:
+ </p>
+<pre>
+[credentials-test]
+authname=fred
+password=123456
+
+[credentials-prod]
+authname=bar
+password=letmein
+
+[credentials-dev]
+username=joe
+password=hello</pre>
+
+ <p>
+ The second set of groups provide mappings of credentials to
+ specific machine services. The config file group names compromise
+ the service type and host:
+ </p>
+
+ <pre>
+[auth-$SERVICE-$HOSTNAME]
+credentials=$CREDENTIALS</pre>
+
+ <p>
+ For example, following the previous example, here is how to
+ list some machines
+ </p>
+
+ <pre>
+[auth-libvirt-test1.example.com]
+credentials=test
+
+[auth-libvirt-test2.example.com]
+credentials=test
+
+[auth-libvirt-demo3.example.com]
+credentials=test
+
+[auth-libvirt-prod1.example.com]
+credentials=prod
+
+[auth-esx-dev1.example.com]
+credentials=dev</pre>
+
+ <p>
+ The following service types are known to libvirt
+ </p>
+
+ <ol>
+ <li><code>libvirt</code> - used for connections to a libvirtd
+ server, which is configured with SASL auth</li>
+ <li><code>ssh</code> - used for connections to a Phyp server
+ over SSH</li>
+ <li><code>esx</code> - used for connections to an ESX or
+ VirtualCenter server</li>
+ <li><code>xen</code> - used for connections to a Xen Enterprise
+ sever using XenAPI</li>
+ </ol>
+
+ <p>
+ Applications using libvirt are free to use this same configuration
+ file for storing other credentials. For example, it can be used
+ to storage VNC or SPICE login credentials

+</p>
+<pre>

+password=123456

+[credentials-prod]
+authname=bar
+password=letmein
+
+[credentials-dev]

+password=hello</pre>
+

+ the service type and host:
+</p>
+
+<pre>
+[auth-$SERVICE-$HOSTNAME]
+credentials=$CREDENTIALS</pre>
+

+credentials=test
+
+[auth-libvirt-prod1.example.com]
+credentials=prod
+
+[auth-esx-dev1.example.com]
+credentials=dev</pre>

+<li><code>libvirt</code> - used for connections to a libvirtd

+<li><code>esx</code> - used for connections to an ESX or

+<li><code>xen</code> - used for connections to a Xen Enterprise

This defines the format for the auth credential config file and
provides APIs to access the data. The config file contains

credname1=value1
credname2=value2
eg
[credentials-test]
authname=fred

I'm not always a fan of plain-text passwords; do you have plans to
further enhance this to hook into our virSecret design, where the config
file can list the name of a secret to reference, which in turn will
trigger appropriate calls to the virSecret API to grab credentials on
first use, securely caching them for later uses that need the same
credentials but without the drawbacks of plain-text config files? But
that's future enhancement, and doesn't stop this patch from going in
once you address Osier's review comments.

These credentials are required in order to establish a connection to
libvirt, so we don't have any virSecret APIs available yet. In addition
this is client side, while the virSecret APIs are server side.
Obviously this is not an ideal scenario from a security POV, but it is
an optional feature. If people are using SASL Password auth and want to
automate libvirt logins, there's not much choice in the matter. If they
want something more secure they can setup SSH keys, or policy kit or
Kerberos tickets.
I envisage this as relevant for test/dev scenarios rather than production.

New subject: [libvirt] [PATCH 13/14] Refactor code prompting for SASL credentials
From: "Daniel P. Berrange" <berrange(a)redhat.com>
SASL may prompt for credentials after either a 'start' or 'step'
invocation. In both cases the code to handle this is the same.
Refactor this code into a separate method to reduce the duplication,
since the complexity is about to grow

New subject: [libvirt] [PATCH 13/14] Refactor code prompting for SASL credentials

From: "Daniel P. Berrange"<berrange(a)redhat.com>
SASL may prompt for credentials after either a 'start' or 'step'
invocation. In both cases the code to handle this is the same.
Refactor this code into a separate method to reduce the duplication,
since the complexity is about to grow
