[PATCH 00/10] qemu: Introduce shared_filesystems configuration option
by Andrea Bolognani
An alternative take on [1] based on review feedback.
The need to have something like this in the first place is driven by
KubeVirt (see [2] and [3]). A draft version of this series has been
integrated into KubeVirt and it has been confirmed that it was
effective in removing the need to use LD_PRELOAD hacks in the storage
provider.
CC'ing Stefan so he can have a look at the TPM part and shout if I've
gotten anything wrong :)

[2] https://issues.redhat.com/browse/CNV-34322
[3] https://issues.redhat.com/browse/CNV-39370
Andrea Bolognani (10):
security: Fix alignment
security: Fix name for _virSecurityDACChardevCallbackData
security: Drop virSecurity(DAC|SELinux)RestoreImageLabelSingle()
security: Drop virSecurity(DAC|SELinux)SetImageLabelRelative()
qemu: Tweak augeas schema
qemu: Introduce shared_filesystems configuration option
qemu: Propagate shared_filesystems
utils: Use overrides in virFileIsSharedFS()
qemu: Always set labels for TPM state
NEWS: Document qemu shared_filesystems option

Plans for 10.3.0 release (freeze on Friday 26 Apr)
by Jiri Denemark
We are getting close to 10.3.0 release of libvirt. To aim for the
release on Thursday 02 May I suggest entering the freeze on Friday
26 Apr and tagging RC2 on Tuesday 30 Apr.
I hope this works for everyone.

[RFC PATCH v1 00/15] node_dev_udev: use workerpool and improve nodedev events
by Marc Hartmayer
When an udev event occurs for a mediated device (mdev) the mdev config data
requires an update via mdevctl as the udev event does not contain all config
data. This update needs to occur immediate and to be finished before the libvirt
nodedev event is issued to keep the API usage reliable.
This patch series already contains the patches from a previous patch series
"[RFC PATCH v1 0/5] node_device_udev: small improvements" and has still some
TODO's included and is sent therefore as a RFC.
Boris Fiuczynski (3):
nodedev: fix mdev add udev event data handling
nodedev: immediate update of active config on udev add
nodedev: reset active config data on udev remove event
Marc Hartmayer (12):
node_device_udev: Set @def to NULL
node_device_udev: Remove the timeout if the data is disposed
node_device_udev: Test for mdevctlTimeout != -1
node_device_udev: Add comments about locking
node_device_udev: Take lock if `driver->privateData` is modified
node_device_udev: Add prefix `udev` for udev related data
node_device_udev: Inline `udevRemoveOneDevice`
node_device_udev: Use `stateShutdownPrepare` and `stateShutdownWait`
node_device_udev: Use a worker pool for processing the udev events
node_device_udev: Call `nodeDeviceUpdateMediatedDevices` directly
node_device_udev: Don't take `mdevctl` lock for querying `mdevctl
list`
node_device_udev: Make the code easier to read

[PATCH] libvirt_nss: Fix ERROR() macro
by Michal Privoznik
The purpose of ERROR() macro in our NSS module is to print error
message provided as arguments followed by error string
corresponding to errno. Historically, we've used strerror_r() for
that (please note, we want our NSS module to be free of libvirt
internal functions, or glib even - hence, g_strerror() is off the
table).
Now strerror_r() is documented as:
Returns ... a pointer to a string that the function stores in
buf, or a pointer to some (immutable) static string (in which
case buf is unused).
Therefore, we can't rely the string being stored in the buf and
really need to store the retval and print that instead.
While touching this area, decrease the ebuf size, since its
current size (1KiB) is triggering our stack limit (2KiB) in some
cases.
