When accidentally passing an invalid value of logBufSize to saLogWriteLogAsync() such as a very large number which is caused by not using strlen() on logBuf, it will cause a lot of troubles. Add code to verify if logBufSize is calculated based on logBuf or not and also prevent too big data sent to server side. diff --git a/osaf/libs/agents/saf/lga/lga_api.c b/osaf/libs/agents/saf/lga/lga_api.c --- a/osaf/libs/agents/saf/lga/lga_api.c +++ b/osaf/libs/agents/saf/lga/lga_api.c @@ -996,6 +996,24 @@ static SaAisErrorT handle_log_record(con ais_rc = SA_AIS_ERR_INVALID_PARAM; goto done; } + + if (logRecord->logBuffer->logBuf != NULL) { + SaSizeT size = logRecord->logBuffer->logBufSize; + bool sizeOver = size > strlen((char *)logRecord->logBuffer->logBuf) + 1; + /* Prevent log client accidently assign too big number to logBufSize */ + if (sizeOver == true) { + TRACE("logBufSize > strlen(logBuf) + 1"); + ais_rc = SA_AIS_ERR_INVALID_PARAM; + goto done; + } + + /* Prevent sending too big data to server side */ + if (size > SA_LOG_MAX_RECORD_SIZE) { + TRACE("logBuf data is too big (max: %d)", SA_LOG_MAX_RECORD_SIZE); + ais_rc = SA_AIS_ERR_INVALID_PARAM; + goto done; + } + } } /* Set timeStamp data if not provided by application user */ diff --git a/tests/logsv/tet_saLogStreamOpen_2.c b/tests/logsv/tet_saLogStreamOpen_2.c --- a/tests/logsv/tet_saLogStreamOpen_2.c +++ b/tests/logsv/tet_saLogStreamOpen_2.c @@ -724,6 +724,8 @@ extern void saLogWriteLogAsync_14(void); extern void saLogWriteLogAsync_15(void); extern void saLogWriteLogAsync_16(void); extern void saLogWriteLogAsync_17(void); +extern void saLogWriteLogAsync_18(void); +extern void saLogWriteLogAsync_19(void); extern void saLogWriteLogCallbackT_01(void); extern void saLogWriteLogCallbackT_02(void); extern void saLogWriteLogCallbackT_03(void); @@ -774,6 +776,8 @@ extern void saLogStreamClose_01(void); test_case_add(2, saLogWriteLogAsync_15, "saLogWriteAsyncLog() NTF notificationObject length == 256"); test_case_add(2, saLogWriteLogAsync_16, "saLogWriteAsyncLog() NTF notifyingObject length == 256"); test_case_add(2, saLogWriteLogAsync_17, "saLogWriteLogAsync() Generic logSvcUsrName length == 256"); + test_case_add(2, saLogWriteLogAsync_18, "saLogWriteLogAsync() logBufSize > strlen(logBuf) + 1"); + test_case_add(2, saLogWriteLogAsync_19, "saLogWriteLogAsync() logBufSize > SA_LOG_MAX_RECORD_SIZE"); test_case_add(2, saLogWriteLogCallbackT_01, "saLogWriteLogCallbackT() SA_DISPATCH_ONE"); test_case_add(2, saLogWriteLogCallbackT_02, "saLogWriteLogCallbackT() SA_DISPATCH_ALL"); test_case_add(2, saLogFilterSetCallbackT_01, "saLogFilterSetCallbackT OK"); diff --git a/tests/logsv/tet_saLogWriteLogAsync.c b/tests/logsv/tet_saLogWriteLogAsync.c --- a/tests/logsv/tet_saLogWriteLogAsync.c +++ b/tests/logsv/tet_saLogWriteLogAsync.c @@ -514,3 +514,41 @@ void saLogWriteLogAsync_17(void) test_validate(rc1, SA_AIS_ERR_INVALID_PARAM); } } + +/** + * saLogWriteAsyncLog() - logBufSize > strlen(logBuf) + 1 + */ +void saLogWriteLogAsync_18(void) +{ + SaInvocationT invocation = 0; + + strcpy((char*)genLogRecord.logBuffer->logBuf, __FUNCTION__); + genLogRecord.logBuffer->logBufSize = strlen(__FUNCTION__) + 2; + safassert(saLogInitialize(&logHandle, &logCallbacks, &logVersion), SA_AIS_OK); + safassert(saLogStreamOpen_2(logHandle, &systemStreamName, NULL, 0, + SA_TIME_ONE_SECOND, &logStreamHandle), SA_AIS_OK); + rc = saLogWriteLogAsync(logStreamHandle, invocation, 0, &genLogRecord); + safassert(saLogFinalize(logHandle), SA_AIS_OK); + test_validate(rc, SA_AIS_ERR_INVALID_PARAM); +} + +/** + * saLogWriteAsyncLog() - big logBufSize > SA_LOG_MAX_RECORD_SIZE + */ +void saLogWriteLogAsync_19(void) +{ + SaInvocationT invocation = 0; + char logBuf[SA_LOG_MAX_RECORD_SIZE + 10]; + + memset(logBuf, 'A', sizeof(logBuf)); + logBuf[sizeof(logBuf) - 1] = '\0'; + + genLogRecord.logBuffer->logBuf = (SaUint8T *)&logBuf; + genLogRecord.logBuffer->logBufSize = SA_LOG_MAX_RECORD_SIZE + 10; + safassert(saLogInitialize(&logHandle, &logCallbacks, &logVersion), SA_AIS_OK); + safassert(saLogStreamOpen_2(logHandle, &systemStreamName, NULL, 0, + SA_TIME_ONE_SECOND, &logStreamHandle), SA_AIS_OK); + rc = saLogWriteLogAsync(logStreamHandle, invocation, 0, &genLogRecord); + safassert(saLogFinalize(logHandle), SA_AIS_OK); + test_validate(rc, SA_AIS_ERR_INVALID_PARAM); +} ------------------------------------------------------------------------------ Find and fix application performance issues faster with Applications Manager Applications Manager provides deep performance insights into multiple tiers of your business applications.
