[PATCH] network: allow "modify" option for DNS-Txt records
by Adam Julis
The "modify" command allows to replace an existing record (its
text value). The primary key is the name of the record. If
duplicity or missing record detected, throw error.
Tests in networkxml2xmlupdatetest.c contain replacements of an
existing DNS-text record and failure due to non-existing record.

[PATCH] network: allow "modify" option for DNS hostname
by Adam Julis
The "modify" command allows you to replace an existing record
(its hostname, sub-elements). IP address acts as the primary key.
If it is not found, the attempt ends with an error message. If
the XML contains a duplicate address, it will select the last
one.
Tests in networkxml2xmlupdatetest.c contain replacements of an
existing DNS-Host record and failure due to non-existing record.

[PATCH] virt-aa-helper: Drop needless comments
by Michal Privoznik
When generating paths for a domain specific AppArmor profile each
path undergoes a validation where it's matched against an array
of well known prefixes (among other things). Now, for
OVMF/AAVMF/... images we have a list and some entries have
comments to which type of image the entry belongs to. For
instance:
"/usr/share/OVMF/", /* for OVMF images */
"/usr/share/AAVMF/", /* for AAVMF images */
But these comments are pretty useless. The path itself already
gives away the image type. Drop them.

[PATCH v3 0/2] security_manager: Fix security manager deadlock after libvirtd fork()
by hongmianquan
We have the stack security driver, which internally manages other security drivers,
just call them "top" and "nested".
We call virSecurityStackPreFork() to lock the top one, and it also locks
and then unlocks the nested drivers prior to fork. Then in qemuSecurityPostFork(),
it unlocks the top one, but not the nested ones. Thus, if one of the nested
drivers ("dac" or "selinux") is still locked, it will cause a deadlock. If we always
surround nested locks with top lock, it is always secure. Because we have got top lock
before fork child libvirtd.
However, it is not always the case in the current code, We discovered this case:
the nested list obtained through the qemuSecurityGetNested() will be locked directly
for subsequent use, such as in virQEMUDriverCreateCapabilities(), where the nested list
is locked using qemuSecurityGetDOI, but the top one is not locked beforehand.
The problem stack is as follows:
libvirtd thread1 libvirtd thread2 child libvirtd
| | |
| | |
virsh capabilities qemuProcessLanuch |
| | |
| lock top |
| | |
lock nested | |
| | |
| fork------------------->|(nested lock held by thread1)
| | |
| | |
unlock nested unlock top unlock top
|
|
qemuSecuritySetSocketLabel
|
|
lock nested (deadlock)
v3 changes:
Made modifications based on Michal's comments
- ensured matching qemuSecurityStackLock() and qemuSecurityStackUnlock()
- modify the correct order in libvirt_private.syms
- split the code streamlining part into a separate patch

[PATCH 0/1] qemuDomainChangeNet: check virtio options for non-virtio models
by Miroslav Los
Hi,
in our project, we create all of our domain interfaces regardless of model
with a <driver><host csum='off'/></driver>. The documentation is not clear
as to which models support offloading or not, and the domain validates.
In libvirtd, since <driver> is present, this causes each network device
to have its virDomainVirtioOptions *virtio to be non-NULL, with all members
ABSENT, which is also deemed valid.
However, clients receive the interface elements without the driver. When
the modified value is sent back via updateDeviceFlags, the candidate's
virtio attribute is thus NULL.
The validation in qemuDomainChangeNet requires both structs to be equal
or both NULL, which is violated by such a request. This can be seen also
with how virsh domif-setlink operates:
virsh # domiflist 5
Interface Type Source Model MAC
--------------------------------------------------------
- udp - e1000 52:54:00:1c:10:42
- udp - e1000 52:54:00:09:29:9c
- udp - e1000 52:54:00:1d:a6:8d
- udp - e1000 52:54:00:07:4a:83
52:54:00:1c:10:42 up
virsh # domif-setlink 5 52:54:00:1c:10:42 down
error: Failed to update interface link state
error: Operation not supported: cannot modify virtio network device driver options
A workaround is to add an empty <driver> in the update request, which works
until libvirt is restarted. The driver element on a non-virtio interface is not
present when the domain is reloaded, thus the pointer is NULL in olddev, causing
the inverse issue and same error.
Our current workaround is to retry with the empty driver element only if the first
call fails, but we think libvirt should handle this struct more consistently.
This patch expands the check to the non-virtio case, where the olddev is assumed
to be valid, and newdev's virtio options are validated to be NULL or all-ABSENT.
Since the driver element is normally preserved for virtio models, the stricter
equality condition is left unchanged in that case.
I did not investigate further if the discrepancy between NULL and all-ABSENT values
for virDomainVirtioOptions can cause a problem elsewhere, or in other device kinds.
Though I do wonder if the options handling should be improved.
One possibility is that non-virtio devices keep the value NULL, e.g. after
validating that the driver element does not contain any of the options, whereas
virtio devices always create the struct even with no driver element present on input.
Another option is that NULL pointer is treated the same as all-ABSENT struct, e.g.
in virDomainCheckVirtioOptionsAreAbsent and virDomainVirtioOptionsCheckABIStability;
the former does that while the latter does not. These functions would also need
to become callable from the qemu driver.

[PATCH] vmx: Do not require all ID data for VMWare Distributed Switch
by Martin Kletzander
Similarly to commit 2482801608b8 we can safely ignore connectionId,
portId and portgroupId in both XML and VMX as they are only a blind
pass-through between XML and VMX and an ethernet without such parameters
was spotted in the wild. On top of that even our documentation says the
whole VMWare Distrubuted Switch configuration is a best-effort.
Resolves: https://issues.redhat.com/browse/RHEL-46099
