[libvirt] [PATCH] Resolve Coverity complaints in tests/securityselinuxlabeltest.c
by John Ferlan 08 Jul '13

08 Jul '13

Two complaints of RESOURCE_FREE due to going to cleanup prior to a VIR_FREE(line). Two complaints of FORWARD_NULL due to 'tmp' being accessed after a strchr() without first checking if the return was NULL. While looking at the code it seems that 'line' need only be allocated once as the while loop will keep reading into line until eof causing an unreported leak since line was never VIR_FREE()'d at the bottom of the loop. --- tests/securityselinuxlabeltest.c | 30 +++++++++++++++++++----------- 1 file changed, 19 insertions(+), 11 deletions(-) diff --git a/tests/securityselinuxlabeltest.c b/tests/securityselinuxlabeltest.c index 5ae4f57..d2ba49b 100644 --- a/tests/securityselinuxlabeltest.c +++ b/tests/securityselinuxlabeltest.c @@ -79,6 +79,7 @@ testSELinuxLoadFileList(const char *testname, int ret = -1; char *path = NULL; FILE *fp = NULL; + char *line = NULL; *files = NULL; *nfiles = 0; @@ -93,37 +94,43 @@ testSELinuxLoadFileList(const char *testname, goto cleanup; } + if (VIR_ALLOC_N(line, 1024) < 0) { + virReportOOMError(); + goto cleanup; + } + while (!feof(fp)) { - char *line; - char *file, *context; - if (VIR_ALLOC_N(line, 1024) < 0) { - virReportOOMError(); - goto cleanup; - } + char *file, *context, *tmp; if (!fgets(line, 1024, fp)) { if (!feof(fp)) goto cleanup; break; } - char *tmp = strchr(line, ';'); + tmp = strchr(line, ';'); + if (!tmp) { + virReportError(VIR_ERR_INTERNAL_ERROR, + "unexpected format for line '%s'", + line); + goto cleanup; + } *tmp = '\0'; tmp++; - if (virAsprintf(&file, "%s/securityselinuxlabeldata%s", abs_builddir, line) < 0) { - VIR_FREE(line); + if (virAsprintf(&file, "%s/securityselinuxlabeldata%s", + abs_builddir, line) < 0) { virReportOOMError(); goto cleanup; } if (*tmp != '\0' && *tmp != '\n') { if (VIR_STRDUP(context, tmp) < 0) { - VIR_FREE(line); VIR_FREE(file); goto cleanup; } tmp = strchr(context, '\n'); - *tmp = '\0'; + if (tmp) + *tmp = '\0'; } else { context = NULL; } @@ -142,6 +149,7 @@ testSELinuxLoadFileList(const char *testname, cleanup: VIR_FORCE_FCLOSE(fp); VIR_FREE(path); + VIR_FREE(line); return ret; } -- 1.8.1.4

[libvirt] [PATCH 0/3] qemu: Make setting memory limits consistent
by Jiri Denemark 08 Jul '13

08 Jul '13

We need to set memory limits in several cases: - when setting hard_limit in memory cgroup - when starting a domain with a VFIO PCI device attached - when hotplugging a VFIO PCI device - when memoryBacking/locked is used This series makes use of a shared code to compute the limits in all of those cases.

[libvirt] [PATCH] add checking index for pci-bridge controller
by Jincheng Miao 08 Jul '13

08 Jul '13

hi all, There is a bug here https://bugzilla.redhat.com/show_bug.cgi?id=981261 about controller configuration. For the pci-bridge controller, if index less than zero, there is no alert for it, and libvirt will pass this value to qemu-kvm. But qemu-kvm will report the argument error, like: "qemu-kvm: -device pci-bridge,chassis_nr=-1,id=pci.-1,bus=pci.0,addr=0x9: Parameter 'chassis_nr' expects uint8_t" So libvirt should check the arguments of controller. Here is my patch for pci-bridge： --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -5693,6 +5693,14 @@ virDomainControllerDefParseXML(xmlNodePtr node, "have an address")); goto error; } + case VIR_DOMAIN_CONTROLLER_MODEL_PCI_BRIDGE: + if (def->idx < 0) { + virReportError(VIR_ERR_XML_ERROR, "%s", + _("pci-bridge controller index invalid, should not " + "less than zero")); + goto error; + } + } And I also see qemuBuildControllerDevStr() in qemu_command.c case VIR_DOMAIN_CONTROLLER_MODEL_PCI_BRIDGE: if (def->idx == 0) { virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", _("PCI bridge index should be > 0")); goto error; } virBufferAsprintf(&buf, "pci-bridge,chassis_nr=%d,id=pci.%d", def->idx, def->idx); And if I modify it to "def->idx > 0", testsuite will fail. So why only check "def->idx == 0" ? Thanks and regards Jincheng Miao

[libvirt] [PATCH] usb: Correct test for virUSBDeviceListSteal
by Gonglei (Arei) 06 Jul '13

In the for loop, the if condition is always true, and will execute memmove. But it will cause the list->devs[i+1] overflow while i equals list->count-1.

[libvirt] [PATCH glib] Fix name of gvir_config_domain_chardev_source_pty_set_path
by Daniel P. Berrange 05 Jul '13

05 Jul '13

From: "Daniel P. Berrange" <berrange(a)redhat.com> The method gvir_config_domain_chardev_source_pty_set_path was accidentally called gvir_config_domain_source_pty_set_path. This naming flaw in turn caused the introspection data to be incorrectly generated, putting a 'source_pty_set_path' method on the GVirConfigDomain object. --- libvirt-gconfig/libvirt-gconfig-domain-chardev-source-pty.c | 4 ++-- libvirt-gconfig/libvirt-gconfig-domain-chardev-source-pty.h | 4 ++-- libvirt-gconfig/libvirt-gconfig.sym | 2 +- 3 files changed, 5 insertions(+), 5 deletions(-) diff --git a/libvirt-gconfig/libvirt-gconfig-domain-chardev-source-pty.c b/libvirt-gconfig/libvirt-gconfig-domain-chardev-source-pty.c index 278515c..d24385e 100644 --- a/libvirt-gconfig/libvirt-gconfig-domain-chardev-source-pty.c +++ b/libvirt-gconfig/libvirt-gconfig-domain-chardev-source-pty.c @@ -82,8 +82,8 @@ GVirConfigDomainChardevSourcePty *gvir_config_domain_chardev_source_pty_new_from return GVIR_CONFIG_DOMAIN_CHARDEV_SOURCE_PTY(object); } -void gvir_config_domain_source_pty_set_path(GVirConfigDomainChardevSourcePty *pty, - const char *path) +void gvir_config_domain_chardev_source_pty_set_path(GVirConfigDomainChardevSourcePty *pty, + const char *path) { g_return_if_fail(GVIR_CONFIG_IS_DOMAIN_CHARDEV_SOURCE_PTY(pty)); diff --git a/libvirt-gconfig/libvirt-gconfig-domain-chardev-source-pty.h b/libvirt-gconfig/libvirt-gconfig-domain-chardev-source-pty.h index 4e350e0..96e05bc 100644 --- a/libvirt-gconfig/libvirt-gconfig-domain-chardev-source-pty.h +++ b/libvirt-gconfig/libvirt-gconfig-domain-chardev-source-pty.h @@ -62,8 +62,8 @@ GType gvir_config_domain_chardev_source_pty_get_type(void); GVirConfigDomainChardevSourcePty *gvir_config_domain_chardev_source_pty_new(void); GVirConfigDomainChardevSourcePty *gvir_config_domain_chardev_source_pty_new_from_xml(const gchar *xml, GError **error); -void gvir_config_domain_source_pty_set_path(GVirConfigDomainChardevSourcePty *pty, - const char *path); +void gvir_config_domain_chardev_source_pty_set_path(GVirConfigDomainChardevSourcePty *pty, + const char *path); G_END_DECLS diff --git a/libvirt-gconfig/libvirt-gconfig.sym b/libvirt-gconfig/libvirt-gconfig.sym index ccddd88..f8c7cdd 100644 --- a/libvirt-gconfig/libvirt-gconfig.sym +++ b/libvirt-gconfig/libvirt-gconfig.sym @@ -66,7 +66,7 @@ LIBVIRT_GCONFIG_0.0.8 { gvir_config_domain_chardev_source_pty_get_type; gvir_config_domain_chardev_source_pty_new; gvir_config_domain_chardev_source_pty_new_from_xml; - gvir_config_domain_source_pty_set_path; + gvir_config_domain_chardev_source_pty_set_path; gvir_config_domain_chardev_source_spicevmc_get_type; gvir_config_domain_chardev_source_spicevmc_new; -- 1.8.2.1
