[PATCH 0/7] storage_file_probe: Handle qcow2 images with 'protocol' driver name in 'backing file format' field (part 1 - the fix)
by Peter Krempa
See 6/7 and 7/7 for the rationale. Further patches will be posted to
refactor the rest of the parsers which are bitrotten.
Peter Krempa (7):
storage_file_probe: Remove unused state 'BACKING_STORE_ERROR'
virStorageFileProbeGetMetadata: Do not partially skip probing of the
image
storage_file_probe: Remove BACKING_STORE_OK,BACKING_STORE_INVALID
states
virstoragetest: Use strings for storage type and format in output data
virstoragetest: Format detected/unprocessed backing store format into
output files
virstoragetest: Add test cases for QCOW2 files with a protocol name as
backing file format
storage_file_probe: Treat qcow2 images with protocol drivers in
backing store field as raw

[PATCH] virnuma: Avoid integer overflow in virNumaGetPages()
by Michal Privoznik
On systems with humongous pages (16GiB) and 32bit int it's easy
to hit integer overflow in virNumaGetPages(). What happens is,
inside of virNumaGetPages() as we process hugepages for given
NUMA node (e.g. in order to produce capabilities XML), we keep a
sum of sizes of pools in an ULL variable (huge_page_sum). In each
iteration, the variable is incremented by 1024 * page_size *
page_avail. Now, page_size is just an uint, so we have:
ULL += U * U * ULL;
and because of associativity, U * U is computed first and since
we have two operands of the same type, no type expansion happens.
But this means, for humongous pages (like 16GiB) the
multiplication overflows.
Therefore, move the multiplication out of the loop. This helps in
two ways:
1) now we have ULL += U * ULL; which expands the uint in
multiplication,
2) it saves couple of CPU cycles.

[PATCH 0/3] lib: Replace qsort() with g_qsort_with_data()
by Michal Privoznik
Technically, this is a v2 of:

but it implements a different approach, so I'm sending it anew.

[libvirt PATCH v2 0/5] ci: Build RPMs on MinGW
by Andrea Bolognani
Test pipeline: https://gitlab.com/abologna/libvirt/-/pipelines/1075354744
Ignore the macOS 14 failure, it's caused by a temporary issue on the
Cirrus CI side.
Changes since [v1]:
* a few patches have either been pushed (1-4) or are no longer
needed (10), so they have been dropped;
* the last patch has been tweaked a bit and the changes contained
in it are now documented with a code comment.
[v1] https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/thread/Y2...
Andrea Bolognani (5):
rpm: Shuffle BuildRequires around
rpm: Split call to mingw_debug_package
rpm: Introduce with_mingw32/with_mingw64
rpm: Introduce with_native
ci: Build RPMs on MinGW

Kernel issue or libvirt issue? Where to report?
by Koos Pol
Hi,
After upgrading the VM host (os + kernel) a VM client can no longer use
a pass-through USB device. The syslog of the VM host is flooded with:
nov 08 19:59:46 vmhost kernel: usb 1-3: usbfs: process 1729
(qemu-system-x86) did not claim interface 1 before use
Because of the upgrade the vm host has gotten both a new kernel version
and a new libvirt verion. The vm client has not been touched.
Before I waste everyone's time on an incorrect bug report, would you say
I file this with libvirt or with the openSUSE kernel (the o.s. of the
vmhost)?
Thanks!
Koos
