# HG changeset patch # User Kaitlin Rupert <karupert(a)us.ibm.com&gt; # Date 1203463635 28800 # Node ID 0d38670abc3cd4be2560daddbd038ebce630f3fb # Parent 95c56a7a865df18bbdf1066d8b04d5d4b75e7d44 Add reference validation to get_migration_service(). Adds reference validation to VirtualSystemMigrationService. Updates: -Initialize inst to NULL in return_vsms() to prevent seg fault -Use pfx_from_conn() in get_migration_service() instead of CLASSNAME(ref) Signed-off-by: Kaitlin Rupert <karupert(a)us.ibm.com&gt; diff -r 95c56a7a865d -r 0d38670abc3c src/Virt_VSMigrationService.c --- a/src/Virt_VSMigrationService.c Tue Feb 19 08:39:04 2008 -0800 +++ b/src/Virt_VSMigrationService.c Tue Feb 19 15:27:15 2008 -0800 @@ -755,15 +755,26 @@ STDIM_MethodMIStub(, Virt_VSMigrationSer CMPIStatus get_migration_service(const CMPIObjectPath *ref, CMPIInstance **_inst, - const CMPIBroker *broker) + const CMPIBroker *broker, + bool is_get_inst) { CMPIInstance *inst; CMPIStatus s = {CMPI_RC_OK, NULL}; + virConnectPtr conn = NULL; const char *name = NULL; const char *ccname = NULL; + conn = connect_by_classname(broker, CLASSNAME(ref), &s); + if (conn == NULL) { + if (is_get_inst) + cu_statusf(broker, &s, + CMPI_RC_ERR_NOT_FOUND, + "No such instance"); + goto out; + } + inst = get_typed_instance(broker, - CLASSNAME(ref), + pfx_from_conn(conn), "VirtualSystemMigrationService", NAMESPACE(ref)); if (inst == NULL) { @@ -793,6 +804,12 @@ CMPIStatus get_migration_service(const C CMSetProperty(inst, "SystemCreationClassName", (CMPIValue *)ccname, CMPI_chars); + if (is_get_inst) { + s = cu_validate_ref(broker, ref, inst); + if (s.rc != CMPI_RC_OK) + goto out; + } + cu_statusf(broker, &s, CMPI_RC_OK, ""); @@ -800,24 +817,28 @@ CMPIStatus get_migration_service(const C *_inst = inst; out: + virConnectClose(conn); + return s; } static CMPIStatus return_vsms(const CMPIObjectPath *ref, const CMPIResult *results, - bool name_only) -{ - CMPIInstance *inst; - CMPIStatus s; - - s = get_migration_service(ref, &inst, _BROKER); - if (s.rc == CMPI_RC_OK) { - if (name_only) - cu_return_instance_name(results, inst); - else - CMReturnInstance(results, inst); - } - + bool name_only, + bool is_get_inst) +{ + CMPIInstance *inst = NULL; + CMPIStatus s; + + s = get_migration_service(ref, &inst, _BROKER, is_get_inst); + if ((s.rc != CMPI_RC_OK) || (inst == NULL)) + goto out; + + if (name_only) + cu_return_instance_name(results, inst); + else + CMReturnInstance(results, inst); + out: return s; } @@ -826,7 +847,7 @@ static CMPIStatus EnumInstanceNames(CMPI const CMPIResult *results, const CMPIObjectPath *ref) { - return return_vsms(ref, results, true); + return return_vsms(ref, results, true, false, false); } static CMPIStatus EnumInstances(CMPIInstanceMI *self, @@ -836,7 +857,7 @@ static CMPIStatus EnumInstances(CMPIInst const char **properties) { - return return_vsms(ref, results, false); + return return_vsms(ref, results, false, false, false); } @@ -846,24 +867,7 @@ static CMPIStatus GetInstance(CMPIInstan const CMPIObjectPath *ref, const char **properties) { - CMPIInstance *inst; - CMPIStatus s; - const char *prop; - - s = get_migration_service(ref, &inst, _BROKER); - if (s.rc != CMPI_RC_OK) - return s; - - prop = cu_compare_ref(ref, inst); - if (prop != NULL) { - cu_statusf(_BROKER, &s, - CMPI_RC_ERR_NOT_FOUND, - "No such instance (%s)", prop); - } else { - CMReturnInstance(results, inst); - } - - return s; + return return_vsms(ref, results, false, true, true); } DEFAULT_CI(); diff -r 95c56a7a865d -r 0d38670abc3c src/Virt_VSMigrationService.h --- a/src/Virt_VSMigrationService.h Tue Feb 19 08:39:04 2008 -0800 +++ b/src/Virt_VSMigrationService.h Tue Feb 19 15:27:15 2008 -0800 @@ -21,7 +21,8 @@ CMPIStatus get_migration_service(const CMPIObjectPath *reference, CMPIInstance **_inst, - const CMPIBroker *broker); + const CMPIBroker *broker, + bool is_get_inst); /* * Local Variables:
