On 32 bit systems there are two tests failing currently: qemufirmwaretest and qemuxml2argvtest (not every test case in them is failing, only some of them). There are several problems: 1) in qemufirmwaretest it's 'QEMU FW precedence test' which is failing. This is because the code tests qemuFirmwareFetchConfigs() which tries to compile a list of some paths from the system and if one of the paths is an empty file it should not appear on the returned list. The code uses virFileLength() to query the file size which uses stat() under the hood. The test uses virfilewrapper to redirect stat() into qemufirmwaredata/ but for reasons beyond me real_stat() returns mangled buffer making the code see a file with a real size even for empty files. I've track this one to a problem in virfilewrapper.c which will call real___xstat() which points to a function in libvirt.so (!) which returns stat with 32bit members even though we're compiling with LARGE_FILE and therefore expect 64bit members in the stat struct. 2) qemuxml2argvtest has two tests failing: 2a) [aarch64-]os-firmware-* - These fail because of the same reason as described in 1) 2b) pseries-hostdevs-* - These fail because they again rely on some stat (lstat to be precise). When building the cmd line for these test cases the code does some search in /sys/bus/pci/... and since we have virpcimock everything works just fine. Except when virfilewrapper.c is linked in because then lstat() is taken from there and when it initializes itself it will lookup real_lstat() which will now point not to virpcimock but to glibc. Again, reasons beyond me. Signed-off-by: Michal Privoznik <mprivozn@xxxxxxxxxx> --- Quite frankly, I hate this patch. But the problem is in our mocking, not in the actual code its testing. And I've tried everything I was able to come up with on how to fix this. So if you have any idea, I'm all ears. tests/qemufirmwaretest.c | 7 +++++++ tests/qemuxml2argvtest.c | 6 ++++++ 2 files changed, 13 insertions(+) diff --git a/tests/qemufirmwaretest.c b/tests/qemufirmwaretest.c index 2b5cbf649b..3332bf0a34 100644 --- a/tests/qemufirmwaretest.c +++ b/tests/qemufirmwaretest.c @@ -52,6 +52,8 @@ testParseFormatFW(const void *opaque) } +#if defined(__x86_64__) || defined(__amd64__) || defined(__aarch64__) +/* XXX Dirty hack, but mocking stat on 32bits is above my skills */ static int testFWPrecedence(const void *opaque ATTRIBUTE_UNUSED) { @@ -97,6 +99,7 @@ testFWPrecedence(const void *opaque ATTRIBUTE_UNUSED) return 0; } +#endif static int @@ -124,8 +127,12 @@ mymain(void) DO_PARSE_TEST("usr/share/qemu/firmware/61-ovmf.json"); DO_PARSE_TEST("usr/share/qemu/firmware/70-aavmf.json"); + +#if defined(__x86_64__) || defined(__amd64__) || defined(__aarch64__) + /* XXX Dirty hack, but mocking stat on 32bits is above my skills */ if (virTestRun("QEMU FW precedence test", testFWPrecedence, NULL) < 0) ret = -1; +#endif virFileWrapperClearPrefixes(); diff --git a/tests/qemuxml2argvtest.c b/tests/qemuxml2argvtest.c index 0c0dcae197..364792d24d 100644 --- a/tests/qemuxml2argvtest.c +++ b/tests/qemuxml2argvtest.c @@ -2038,6 +2038,8 @@ mymain(void) DO_TEST("pseries-many-buses-2", QEMU_CAPS_DEVICE_SPAPR_PCI_HOST_BRIDGE, QEMU_CAPS_VIRTIO_SCSI); +# if defined(__x86_64__) || defined(__amd64__) || defined(__aarch64__) + /* XXX Dirty hack, but mocking stat on 32bits is above my skills */ DO_TEST("pseries-hostdevs-1", QEMU_CAPS_DEVICE_SPAPR_PCI_HOST_BRIDGE, QEMU_CAPS_VIRTIO_SCSI, @@ -2050,6 +2052,7 @@ mymain(void) QEMU_CAPS_DEVICE_SPAPR_PCI_HOST_BRIDGE, QEMU_CAPS_VIRTIO_SCSI, QEMU_CAPS_DEVICE_VFIO_PCI); +# endif DO_TEST("pseries-features", QEMU_CAPS_DEVICE_SPAPR_PCI_HOST_BRIDGE, @@ -3157,10 +3160,13 @@ mymain(void) DO_TEST_CAPS_ARCH_LATEST("x86_64-pc-graphics", "x86_64"); DO_TEST_CAPS_ARCH_LATEST("x86_64-q35-graphics", "x86_64"); +# if defined(__x86_64__) || defined(__amd64__) || defined(__aarch64__) + /* XXX Dirty hack, but mocking stat on 32bits is above my skills */ DO_TEST_CAPS_LATEST("os-firmware-bios"); DO_TEST_CAPS_LATEST("os-firmware-efi"); DO_TEST_CAPS_LATEST("os-firmware-efi-secboot"); DO_TEST_CAPS_ARCH_LATEST("aarch64-os-firmware-efi", "aarch64"); +# endif if (getenv("LIBVIRT_SKIP_CLEANUP") == NULL) virFileDeleteTree(fakerootdir); -- 2.19.2 -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
