[PATCH v2 0/6] Introduce active RBD disk snapshot support
by Or Ozeri 22 Mar '23

22 Mar '23

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 docs/formatsnapshot.rst | 5 + src/conf/schemas/domainsnapshot.rng | 4 + src/conf/snapshot_conf.c | 56 ++++++++++ src/conf/snapshot_conf.h | 5 + src/libvirt_private.syms | 1 + src/qemu/qemu_monitor.c | 9 ++ src/qemu/qemu_monitor.h | 5 + src/qemu/qemu_monitor_json.c | 14 +++ src/qemu/qemu_monitor_json.h | 5 + src/qemu/qemu_snapshot.c | 105 ++++++++++++------ .../disk_snapshot.xml | 2 +- .../disk_snapshot.xml | 2 +- .../disk_snapshot_redefine.xml | 2 +- tests/qemumonitorjsontest.c | 1 + 14 files changed, 181 insertions(+), 35 deletions(-) -- 2.25.1

[PATCH] meson: Disable optimizations if CLang doesn't support -fsemantic-interposition
by Michal Privoznik 22 Mar '23

22 Mar '23

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 21 Mar '23

21 Mar '23

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): 116f5f: e8 0c b7 f9 ff call b2670 <virBitmapNew@plt> 116f64: 48 89 44 24 40 mov %rax,0x40(%rsp) 116f69: 48 c7 44 24 18 ff ff movq $0xffffffffffffffff,0x18(%rsp) 116f70: ff ff 116f72: 48 8b 7c 24 38 mov 0x38(%rsp),%rdi 116f77: 48 8b 74 24 18 mov 0x18(%rsp),%rsi 116f7c: e8 0f 74 f9 ff call ae390 <virBitmapNextSetBit@plt> 116f81: eb 00 jmp 116f83 <virNumaCPUSetToNodeset+0x43> 116f83: 48 89 44 24 18 mov %rax,0x18(%rsp) 116f88: 48 83 f8 00 cmp $0x0,%rax 116f8c: 0f 8c b2 00 00 00 jl 117044 <virNumaCPUSetToNodeset+0x104> 116f92: 48 8b 7c 24 18 mov 0x18(%rsp),%rdi 116f97: e8 d4 a1 f9 ff call b1170 <virNumaGetNodeOfCPU@plt> 116f9c: c7 44 24 10 ff ff ff movl $0xffffffff,0x10(%rsp) 116fa3: ff 116fa4: 83 7c 24 10 00 cmpl $0x0,0x10(%rsp) 116fa9: 7d 74 jge 11701f <virNumaCPUSetToNodeset+0xdf> 116fab: e8 80 72 f9 ff call ae230 <__errno_location@plt> 116fb0: 8b 18 mov (%rax),%ebx 116fb2: 48 8d 3d 27 35 2b 00 lea 0x2b3527(%rip),%rdi # 3ca4e0 <vmdk4GetBackingStore.prefix+0xf260> 116fb9: 48 8d 35 8c e3 25 00 lea 0x25e38c(%rip),%rsi # 37534c <modeMap+0x215c> 116fc0: ba 05 00 00 00 mov $0x5,%edx 116fc5: e8 e6 a7 f9 ff call b17b0 <dcgettext@plt> 116fca: 48 8b 4c 24 18 mov 0x18(%rsp),%rcx 116fcf: 48 89 0c 24 mov %rcx,(%rsp) 116fd3: 48 8d 15 ea e0 25 00 lea 0x25e0ea(%rip),%rdx # 3750c4 <modeMap+0x1ed4> 116fda: 48 8d 0d 54 e3 25 00 lea 0x25e354(%rip),%rcx # 375335 <modeMap+0x2145> 116fe1: 31 ff xor %edi,%edi 116fe3: 89 de mov %ebx,%esi 116fe5: 41 b8 10 04 00 00 mov $0x410,%r8d 116feb: 49 89 c1 mov %rax,%r9 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.

[PATCH v2] meson: Stop detecting -Wl,--version-script=
by Michal Privoznik 21 Mar '23

21 Mar '23

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. 1: https://reviews.llvm.org/D135402 2: https://github.com/mesonbuild/meson/issues/3047 Resolves: https://bugs.gentoo.org/902211 Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- v2 of: https://listman.redhat.com/archives/libvir-list/2023-March/238923.html diff to v1: - Instead of fixing the detection, drop it completely. meson.build | 7 +------ 1 file changed, 1 insertion(+), 6 deletions(-) diff --git a/meson.build b/meson.build index c35823a79a..a0682e8d0b 100644 --- a/meson.build +++ b/meson.build @@ -534,12 +534,7 @@ elif host_machine.system() == 'darwin' # macOS libraries don't support symbol versioning version_script_flags = '' else - test_file = '@0@/src/libvirt_qemu.syms'.format(meson.project_source_root()) - if cc.has_link_argument('-Wl,--version-script=@0@'.format(test_file)) - version_script_flags = '-Wl,--version-script=' - else - error('No supported version script link argument found.') - endif + version_script_flags = '-Wl,--version-script=' endif libvirt_flat_namespace = [] -- 2.39.2

[PATCH] meson: Work around too strict lld
by Michal Privoznik 21 Mar '23

21 Mar '23

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]. 1: https://reviews.llvm.org/D135402 2: https://github.com/mesonbuild/meson/issues/3047 Resolves: https://bugs.gentoo.org/902211 Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- Compile Libvirt?

[PATCH 1/1] capabilities: reduce scope in virCapabilitiesInitCaches()
