New subject: [libvirt] [PATCH 2/2] Fix seclabels for chardevs
We allow a seclabel to be specified in the <source> element
of a chardev:
<serial type='file'>
<source path='/tmp/serial.file'>
<seclabel model='dac' relabel='no'/>
</source>
</serial>
But we format it outside the source:
<serial type='file'>
<source path='/tmp/serial.file'/>
<target port='0'/>
<seclabel model='dac' relabel='no'/>
</serial>
Move the formatting inside the source to fix this to make the
seclabel persistent across XML format->parse.
Introduced by commit f8b08d0 'Add <seclabel> to character devices.'

There is one paragraph mentioning that in the XML format documentation.
I think it would be worth adding (as a separate patch) an example of the
usage too.
But we format it outside the source:
<serial type='file'>
<source path='/tmp/serial.file'/>
<target port='0'/>
<seclabel model='dac' relabel='no'/>
</serial>

Nice test, but add a device:

<source path='/dev/null'/>
</backend>
</rng>
This will lead with the code in this patch to the crash described above.

New subject: [libvirt] [PATCHv2] conf: fix seclabels for chardevs
On 05/16/14 16:57, Ján Tomko wrote:
We allow a seclabel to be specified in the <source> element
of a chardev:
<serial type='file'>
<source path='/tmp/serial.file'>
<seclabel model='dac' relabel='no'/>
</source>
</serial>
But we format it outside the source:
<serial type='file'>
<source path='/tmp/serial.file'/>
<target port='0'/>
<seclabel model='dac' relabel='no'/>
</serial>
Move the formatting inside the source to fix this to make the
seclabel persistent across XML format->parse.
Introduced by commit f8b08d0 'Add <seclabel> to character devices.'
