[PATCH v2 0/6] Introduce active RBD disk snapshot support
by Or Ozeri
Internal disk snapshots are currently only supported on non-active VMs.
For RBD disks only, this patch series extends this support for active VMs running with qemu.
We also add the option to set a name for each RBD snapshot, and allow taking them alongside other external disk snapshots (mixing).
Deletion and reverting to snapshots containing RBD snapshots is not allowed, and is validated.
Note that taking RBD snapshots on a non-active VM is still unsupported.
Changes in v2:
- reduce patch to RBD use-case only (e.g. not including qcow2 internal snapshots)
- add validation to disallow RBD snapshots deletion / reverting
Or Ozeri (6):
conf: Add snapshotName attribute for internal disk snapshot
qemu: Block deletion and reverting on non-full internal snapshots
qemu: Add internal support for active disk internal snapshots
qemu: Allow active disk snapshots for RBD disks
qemu: Allow setting per-disk snapshot name for RBD disks
qemu: Allow mixing active internal and external active disk snapshots

[PATCH] meson: Disable optimizations if CLang doesn't support -fsemantic-interposition
by Michal Privoznik
For some older CLang (or in combination with !intel arch) the
-fsemantic-interposition might be not present. But in that case,
we still want our mocking in test suite to work properly. Disable
optimizations as that seems to be the only way.
Also, don't forget to drop this when FreeBSD 11 and macOS 12 are
dropped.

[PATCH 0/2] Work around broken clang. Again.
by Michal Privoznik
We ran into so many clang bugs recently, that I'm strongly in favor of
making it optional and aim on gcc only. Debugging these issues burns our
time needlessly. Just consider what's happening here.
I've pushed patches recently that call some virNuma*() APIs during QEMU
cmd line generation. And while at it, I removed virNuma*() mocks from
qemuxml2argvmock.c (v9.1.0-213-g95ae91fdd4). Andrea told me in review to
make sure our CI works. So I've fired up my freebsd VM and compiled my
code there. It worked. Except, I'm compiling with -O0 and our CI
compiles with the default (-O2). And of course this is the source of the
current build breakage.
Long story short, clang is so eager to produce the fastest code that it
simply ignores written code and generates what it *assumes* behaves the
same. Well, it doesn't and this breaks our mocking and thus our tests.
And of course it's happening only with optimizations.
In this particular case, I've noticed that while
virNumaNodesetIsAvailable() calls virNumaNodeIsAvailable(), it
disregards the return value and virReportError()-s immediately.
This is because the !WITH_NUMACTL variant of virNumaNodeIsAvailable()
calls virNumaGetMaxNode() which fails and thus false is returned.
WORSE, then I stepped in gdb into the mock, I've seen random numbers as
integers. This is because the function from virnumamock.c wasn't
optimized as much and followed standard calling convention (it grabbed
the integer argument from the stack). But the caller
(virNumaNodesetIsAvailable()) was so optimized that it did not even
bothered to push anything onto stack.
After these patches, there is still one qemuxml2argvtest case failing,
and it's simply because no matter how hard I try, I can't stop clang
from optimizing the function. Consider the following code:
virNumaCPUSetToNodeset(virBitmap *cpuset,
virBitmap **nodeset)
{
g_autoptr(virBitmap) nodes = virBitmapNew(0);
ssize_t pos = -1;
while ((pos = virBitmapNextSetBit(cpuset, pos)) >= 0) {
int node = virNumaGetNodeOfCPU(pos);
if (node < 0) {
virReportSystemError(errno,
_("Unable to get NUMA node of cpu %zd"),
pos);
return -1;
}
...
}
...
}
And this is the assembly code that clang generates (even after
VIR_OPTNONE treatment):

116fee: 31 c0 xor %eax,%eax
116ff0: e8 8b c1 f9 ff call b3180 <virReportSystemErrorFull@plt>
My assembler is a bit rusty, but at virNumaGetNodeOfCPU@plt is called
116f97, after which, -1 is stored on a stack (which corresponds to @pos
variable), after which comparison against 0 is made and the jump happens
iff the value (-1) is greater or equal than zero. Otherwise
virReportSystemError() is called.
To reproduce this issue even on Linux, configure with:
export CC=clang
meson setup -Dsystem=true -Dexpensive_tests=enabled -Dnumactl=disabled _build
At this point, I think we can call clang broken and focus our time on
developing libvirt. Not coming up with hacks around broken compilers.

[PATCH v2] meson: Stop detecting -Wl,--version-script=
by Michal Privoznik
With its version 16.0, the LLVM's linker turned on
--no-undefined-version by default [1]. This breaks how we detect
--version-script= detection, because at the compile time there's
no library built yet that we can use to make --version-script=
happy. Unfortunately, meson does not provide a way to detect this
either [2].
But there's not much sense in detecting the argument either. We
already special case some systems (windows, darwin) and do the
check for others, which are expected to support versioned
symbols, because of ELF. Worst case scenario - the error is
reported during compile time rather than configure time.

[PATCH] meson: Work around too strict lld
by Michal Privoznik
With its version 16.0, the LLVM's linker turned on
--no-undefined-version by default [1]. This breaks how we detect
--version-script= detection, because at the compile time there's
no library built yet that we can use to make --version-script=
happy. To cancel their choice of defaults, pass
--undefined-version. Unfortunately, this flag is LLVM's invention
and is not supported by GNU's ld.
This all could be avoided if meson provided proper detection of
supported linker arguments, but we are far away from that [2].

[PATCH 1/1] capabilities: reduce scope in virCapabilitiesInitCaches()
by Shaleen Bathla
over-writing a variable in inner while-loop without freeing previous memory
leaks it over time.
To fix this, we can just change scope of bank variable to the inner loop.
