[libvirt] [PATCH] qemu: Don't overwrite errors by closefd in error paths
by Jiri Denemark 14 Jul '11

14 Jul '11

[libvirt] [PATCH v2] storage: Avoid memory leak on metadata fetching
by Michal Privoznik 14 Jul '11

14 Jul '11

Getting metadata on storage allocates a memory (path) which need to be freed after use otherwise it gets leaked. This means after use of virStorageFileGetMetadataFromFD or virStorageFileGetMetadata one must call virStorageFileFreeMetadata to free it. This function frees structure internals and structure itself. --- diff to v1: -Eric's review suggestions taken in src/conf/domain_conf.c | 17 ++++++++--- src/libvirt_private.syms | 1 + src/storage/storage_backend_fs.c | 53 +++++++++++++++++++++---------------- src/util/storage_file.c | 16 +++++++++++ src/util/storage_file.h | 2 + 5 files changed, 61 insertions(+), 28 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 39e59b9..c89c7c6 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -11055,6 +11055,12 @@ int virDomainDiskDefForeachPath(virDomainDiskDefPtr disk, int ret = -1; size_t depth = 0; char *nextpath = NULL; + virStorageFileMetadata *meta; + + if (VIR_ALLOC(meta) < 0) { + virReportOOMError(); + return ret; + } if (!disk->src || disk->type == VIR_DOMAIN_DISK_TYPE_NETWORK) return 0; @@ -11084,7 +11090,6 @@ int virDomainDiskDefForeachPath(virDomainDiskDefPtr disk, paths = virHashCreate(5, NULL); do { - virStorageFileMetadata meta; const char *path = nextpath ? nextpath : disk->src; int fd; @@ -11112,7 +11117,7 @@ int virDomainDiskDefForeachPath(virDomainDiskDefPtr disk, } } - if (virStorageFileGetMetadataFromFD(path, fd, format, &meta) < 0) { + if (virStorageFileGetMetadataFromFD(path, fd, format, meta) < 0) { VIR_FORCE_CLOSE(fd); goto cleanup; } @@ -11126,16 +11131,17 @@ int virDomainDiskDefForeachPath(virDomainDiskDefPtr disk, goto cleanup; depth++; - nextpath = meta.backingStore; + VIR_FREE(nextpath); + nextpath = meta->backingStore; /* Stop iterating if we reach a non-file backing store */ - if (nextpath && !meta.backingStoreIsFile) { + if (nextpath && !meta->backingStoreIsFile) { VIR_DEBUG("Stopping iteration on non-file backing store: %s", nextpath); break; } - format = meta.backingStoreFormat; + format = meta->backingStoreFormat; if (format == VIR_STORAGE_FILE_AUTO && !allowProbing) @@ -11151,6 +11157,7 @@ int virDomainDiskDefForeachPath(virDomainDiskDefPtr disk, cleanup: virHashFree(paths); VIR_FREE(nextpath); + virStorageFileFreeMetadata(meta); return ret; } diff --git a/src/libvirt_private.syms b/src/libvirt_private.syms index 3237d18..e06c7fc 100644 --- a/src/libvirt_private.syms +++ b/src/libvirt_private.syms @@ -940,6 +940,7 @@ virStorageGenerateQcowPassphrase; # storage_file.h virStorageFileFormatTypeFromString; virStorageFileFormatTypeToString; +virStorageFileFreeMetadata; virStorageFileGetMetadata; virStorageFileGetMetadataFromFD; virStorageFileIsSharedFS; diff --git a/src/storage/storage_backend_fs.c b/src/storage/storage_backend_fs.c index b30e01e..821efb7 100644 --- a/src/storage/storage_backend_fs.c +++ b/src/storage/storage_backend_fs.c @@ -61,8 +61,13 @@ virStorageBackendProbeTarget(virStorageVolTargetPtr target, unsigned long long *capacity, virStorageEncryptionPtr *encryption) { - int fd, ret; - virStorageFileMetadata meta; + int fd = -1, ret = -1; + virStorageFileMetadata *meta; + + if (VIR_ALLOC(meta) < 0) { + virReportOOMError(); + return ret; + } *backingStore = NULL; *backingStoreFormat = VIR_STORAGE_FILE_AUTO; @@ -71,36 +76,33 @@ virStorageBackendProbeTarget(virStorageVolTargetPtr target, if ((ret = virStorageBackendVolOpenCheckMode(target->path, VIR_STORAGE_VOL_FS_REFRESH_FLAGS)) < 0) - return ret; /* Take care to propagate ret, it is not always -1 */ + goto error; /* Take care to propagate ret, it is not always -1 */ fd = ret; if ((ret = virStorageBackendUpdateVolTargetInfoFD(target, fd, allocation, capacity)) < 0) { - VIR_FORCE_CLOSE(fd); - return ret; + goto error; } - memset(&meta, 0, sizeof(meta)); - if ((target->format = virStorageFileProbeFormatFromFD(target->path, fd)) < 0) { - VIR_FORCE_CLOSE(fd); - return -1; + ret = 1; + goto error; } if (virStorageFileGetMetadataFromFD(target->path, fd, target->format, - &meta) < 0) { - VIR_FORCE_CLOSE(fd); - return -1; + meta) < 0) { + ret = -1; + goto error; } VIR_FORCE_CLOSE(fd); - if (meta.backingStore) { - *backingStore = meta.backingStore; - meta.backingStore = NULL; - if (meta.backingStoreFormat == VIR_STORAGE_FILE_AUTO) { + if (meta->backingStore) { + *backingStore = meta->backingStore; + meta->backingStore = NULL; + if (meta->backingStoreFormat == VIR_STORAGE_FILE_AUTO) { if ((ret = virStorageFileProbeFormat(*backingStore)) < 0) { /* If the backing file is currently unavailable, only log an error, * but continue.

[libvirt] RFC on libvirt-qpid naming
by Zane Bitter 14 Jul '11

14 Jul '11

The name libvirt-qpid is probably not as descriptive of the project as it could be. If we want to change the name then now is our best opportunity to do so, as part of the process to convert it to QMFv2 and make it a matahari agent - potentially breaking backward compatibility with existing consoles. As this project is still remaining outside of the matahari project, how do folks feel about changing the name to libvirt-qmf? regards, Zane.

[libvirt] [PATCH] Add basic driver for Microsoft Hyper-V
by Matthias Bolte 13 Jul '11

13 Jul '11

Domain listing, basic information retrieval and domain life cycle management is implemented. But currently the domian XML output lacks the complete devices section. The driver uses OpenWSMAN to directly communicate with an Hyper-V server over its WS-Management interface exposed via Microsoft WinRM. Just like the ESX driver this driver includes a generator that generates the type definitions for the Hyper-V API that are feed to OpenWSMAN. Currently there are some sections in the code that are disabled because of bugs in OpenWSMAN <= 2.2.6. Patches for those problems have been posted upstream. The driver is based on the work of Michael Sievers. This started in the same master program project group at the University of Paderborn as the ESX driver. See Michael's blog for details: http://hyperv4libvirt.wordpress.com/ --- cfg.mk | 1 + configure.ac | 38 + docs/drivers.html.in | 1 + docs/drvhyperv.html.in | 103 +++ docs/index.html.in | 3 + docs/sitemap.html.in | 4 + include/libvirt/virterror.h | 1 + libvirt.spec.in | 9 + po/POTFILES.in | 3 + src/Makefile.am | 52 ++ src/README | 3 +- src/driver.h | 1 + src/hyperv/.gitignore | 1 + src/hyperv/hyperv_device_monitor.c | 77 ++ src/hyperv/hyperv_device_monitor.h | 29 + src/hyperv/hyperv_driver.c | 1275 +++++++++++++++++++++++++++++++++ src/hyperv/hyperv_driver.h | 29 + src/hyperv/hyperv_interface_driver.c | 77 ++ src/hyperv/hyperv_interface_driver.h | 29 + src/hyperv/hyperv_network_driver.c | 80 ++ src/hyperv/hyperv_network_driver.h | 29 + src/hyperv/hyperv_nwfilter_driver.c | 77 ++ src/hyperv/hyperv_nwfilter_driver.h | 29 + src/hyperv/hyperv_private.h | 43 ++ src/hyperv/hyperv_secret_driver.c | 77 ++ src/hyperv/hyperv_secret_driver.h | 29 + src/hyperv/hyperv_storage_driver.c | 79 ++ src/hyperv/hyperv_storage_driver.h | 29 + src/hyperv/hyperv_util.c | 129 ++++ src/hyperv/hyperv_util.h | 39 + src/hyperv/hyperv_wmi.c | 692 ++++++++++++++++++ src/hyperv/hyperv_wmi.h | 119 +++ src/hyperv/hyperv_wmi_classes.c | 37 + src/hyperv/hyperv_wmi_classes.h | 94 +++ src/hyperv/hyperv_wmi_generator.input | 294 ++++++++ src/hyperv/hyperv_wmi_generator.py | 309 ++++++++ src/hyperv/openwsman.h | 47 ++ src/libvirt.c | 12 + src/util/virterror.c | 3 + 39 files changed, 3982 insertions(+), 1 deletions(-) create mode 100644 docs/drvhyperv.html.in create mode 100644 src/hyperv/.gitignore create mode 100644 src/hyperv/hyperv_device_monitor.c create mode 100644 src/hyperv/hyperv_device_monitor.h create mode 100644 src/hyperv/hyperv_driver.c create mode 100644 src/hyperv/hyperv_driver.h create mode 100644 src/hyperv/hyperv_interface_driver.c create mode 100644 src/hyperv/hyperv_interface_driver.h create mode 100644 src/hyperv/hyperv_network_driver.c create mode 100644 src/hyperv/hyperv_network_driver.h create mode 100644 src/hyperv/hyperv_nwfilter_driver.c create mode 100644 src/hyperv/hyperv_nwfilter_driver.h create mode 100644 src/hyperv/hyperv_private.h create mode 100644 src/hyperv/hyperv_secret_driver.c create mode 100644 src/hyperv/hyperv_secret_driver.h create mode 100644 src/hyperv/hyperv_storage_driver.c create mode 100644 src/hyperv/hyperv_storage_driver.h create mode 100644 src/hyperv/hyperv_util.c create mode 100644 src/hyperv/hyperv_util.h create mode 100644 src/hyperv/hyperv_wmi.c create mode 100644 src/hyperv/hyperv_wmi.h create mode 100644 src/hyperv/hyperv_wmi_classes.c create mode 100644 src/hyperv/hyperv_wmi_classes.h create mode 100644 src/hyperv/hyperv_wmi_generator.input create mode 100755 src/hyperv/hyperv_wmi_generator.py create mode 100644 src/hyperv/openwsman.h diff --git a/cfg.mk b/cfg.mk index b00cda3..c20b8c9 100644 --- a/cfg.mk +++ b/cfg.mk @@ -411,6 +411,7 @@ sc_prohibit_xmlGetProp: msg_gen_function = msg_gen_function += ESX_ERROR msg_gen_function += ESX_VI_ERROR +msg_gen_function += HYPERV_ERROR msg_gen_function += PHYP_ERROR msg_gen_function += VIR_ERROR msg_gen_function += VMX_ERROR diff --git a/configure.ac b/configure.ac index e9d5be4..d7ebe79 100644 --- a/configure.ac +++ b/configure.ac @@ -66,6 +66,7 @@ XMLRPC_REQUIRED=1.14.0 HAL_REQUIRED=0.5.0 DEVMAPPER_REQUIRED=1.0.0 LIBCURL_REQUIRED="7.18.0" +OPENWSMAN_REQUIRED="2.2.6" LIBPCAP_REQUIRED="1.0.0" LIBNL_REQUIRED="1.1" LIBSSH2_REQUIRED="1.0" @@ -275,6 +276,8 @@ AC_ARG_WITH([lxc], AC_HELP_STRING([--with-lxc], [add Linux Container support @<:@default=check@:>@]),[],[with_lxc=check]) AC_ARG_WITH([esx], AC_HELP_STRING([--with-esx], [add ESX support @<:@default=check@:>@]),[],[with_esx=check]) +AC_ARG_WITH([hyperv], + AC_HELP_STRING([--with-hyperv], [add Hyper-V support @<:@default=check@:>@]),[],[with_hyperv=check]) AC_ARG_WITH([test], AC_HELP_STRING([--with-test], [add test driver support @<:@default=yes@:>@]),[],[with_test=yes]) AC_ARG_WITH([remote], @@ -1912,6 +1915,35 @@ LIBCURL_CFLAGS="-DCURL_DISABLE_TYPECHECK $LIBCURL_CFLAGS" AC_SUBST([LIBCURL_CFLAGS]) AC_SUBST([LIBCURL_LIBS]) + +dnl +dnl check for openwsman (Hyper-V) +dnl + +OPENWSMAN_CFLAGS="" +OPENWSMAN_LIBS="" + +if test "$with_hyperv" = "yes" || test "$with_hyperv" = "check";
