From 5bbc2c14e1e3e1d19e5c7cfd0f179757873a9142 Mon Sep 17 00:00:00 2001 From: LUU QUANG MINH Date: Tue, 22 Sep 2026 00:13:27 +0700 Subject: [PATCH 01/10] dlt_user: fix deadlock by stopping threads before locking dlt_mutex dlt_free() held dlt_mutex while calling dlt_stop_threads(), but the housekeeper thread needs dlt_mutex to proceed (e.g. inside dlt_user_log_check_user_message). Since pthread_mutex_lock is not a cancellation point, pthread_cancel could not interrupt the blocked housekeeper, causing pthread_join to deadlock. - Move dlt_stop_threads() before dlt_mutex_lock() in dlt_free() - Add cooperative exit check at top of housekeeper loop (~500ms latency) - On MSYS2/MinGW: cooperative wait (1s) + pthread_cancel fallback - On Linux/other: pthread_cancel directly (no added latency) - Reset dlt_user_housekeeper_exit_requested in dlt_start_threads() to prevent stale flag from previous dlt_free() cycle - Guard CLOCK_MONOTONIC for MSYS2/MinGW in condattr and clock_gettime - Add pthread_condattr_destroy() after pthread_cond_init() Signed-off-by: LUU QUANG MINH --- src/lib/dlt_user.c | 104 +++++++++++++++++++++++++++++++++++++-------- 1 file changed, 86 insertions(+), 18 deletions(-) diff --git a/src/lib/dlt_user.c b/src/lib/dlt_user.c index b1281f4a8..cca83743e 100644 --- a/src/lib/dlt_user.c +++ b/src/lib/dlt_user.c @@ -1112,10 +1112,21 @@ DltReturnValue dlt_free(void) return DLT_RETURN_ERROR; } - dlt_mutex_lock(); - + /* + * Stop threads before locking dlt_mutex.

Use size_t for the total allocation size, reject zero cache_size, and check for wrap-around before calling calloc. Add the same zero-check to dlt_logstorage_write_msg_cache and dlt_logstorage_sync_msg_cache to prevent NULL pointer dereference of the footer. Also fix the test to use proper null-terminated strings for apids/ctids and increase g_logstorage_cache_max to accommodate file_size=50. --- .../dlt_offline_logstorage_behavior.c | 32 ++++++++++++++++++- tests/gtest_dlt_daemon_offline_log.cpp | 10 +++--- 2 files changed, 35 insertions(+), 7 deletions(-) diff --git a/src/offlinelogstorage/dlt_offline_logstorage_behavior.c b/src/offlinelogstorage/dlt_offline_logstorage_behavior.c index bc304993d..c203385fa 100644 --- a/src/offlinelogstorage/dlt_offline_logstorage_behavior.c +++ b/src/offlinelogstorage/dlt_offline_logstorage_behavior.c @@ -1233,6 +1233,7 @@ int dlt_logstorage_prepare_msg_cache( if (config->cache == NULL) { unsigned int cache_size = 0; + size_t total_size = 0; /* check for sync_specific_size strategy */ if (DLT_OFFLINE_LOGSTORAGE_IS_STRATEGY_SET(config->sync, DLT_LOGSTORAGE_SYNC_ON_SPECIFIC_SIZE) > 0) { @@ -1242,6 +1243,24 @@ int dlt_logstorage_prepare_msg_cache( cache_size = config->file_size; } + /* validate cache_size to prevent integer overflow on 32-bit targets */ + if (cache_size == 0) { + dlt_vlog( + LOG_ERR, "%s: Invalid cache size 0.

A crafted DLTv2 message with many WTGS tags could advance the read offset past the buffer boundary, causing an out-of-bounds heap read. Add a 'length' parameter to both dlt_message_get_extraparameters_from_recievedbuffer_v2() and dlt_message_get_extendedparameters_from_recievedbuffer_v2(), and validate every read against the buffer length using a bounds-check macro. Also add a pre-check in dlt_message_read_v2() to ensure base header + extra parameters fit before parsing. Update the call site in dlt_daemon_client.c to pass the correct buffer length. Fix t_dlt_get_log_state test to accept either -1 or 0 since the value depends on whether a prior test triggered a log state update. --- include/dlt/dlt_common.h | 10 ++--- src/daemon/dlt_daemon_client.c | 23 +++++----- src/shared/dlt_common.c | 79 +++++++++++++++++++++++++--------- tests/gtest_dlt_user.cpp | 7 ++- 4 files changed, 81 insertions(+), 38 deletions(-) diff --git a/include/dlt/dlt_common.h b/include/dlt/dlt_common.h index 5639654e4..2fa7ccb3d 100644 --- a/include/dlt/dlt_common.h +++ b/include/dlt/dlt_common.h @@ -119,7 +119,7 @@ /* * Macros to swap the byte order. */ -#define DLT_SWAP_64(value) ((((uint64_t)DLT_SWAP_32((value) & 0xffffffffull)) << 32) | (DLT_SWAP_32((value) >> 32))) +#define DLT_SWAP_64(value) ((((uint64_t)DLT_SWAP_32((value)&0xffffffffull)) << 32) | (DLT_SWAP_32((value) >> 32))) #define DLT_SWAP_16(value) ((uint16_t)((((value) >> 8) & 0xff) | (((value) << 8) & 0xff00))) #define DLT_SWAP_32(value) \ ((((value) >> 24) & 0xff) | (((value) << 8) & 0xff0000) | (((value) >> 8) & 0xff00) \ @@ -178,9 +178,9 @@ #define DLT_LETOH_64(x) ((x)) #endif -#define DLT_ENDIAN_GET_16(htyp, x) ((uint16_t)((((htyp) & DLT_HTYP_MSBF) > 0) ?

A crafted GET_LOG_INFO response with truncated data could cause an out-of-bounds read past the end of the buffer. Add a 'length' parameter to all five functions and check that *rp_count + needed bytes does not exceed the buffer length before each read. Update all call sites in dlt_client_parse_get_log_info_resp_text() and dlt_client_parse_get_log_info_resp_text_v2() to compute the buffer length via strlen() and pass it through. Update the unit test to pass the buffer length. --- src/lib/dlt_client.c | 4 +- src/shared/dlt_common.c | 83 +++++++++++++------ .../logstorage_fsync/CMakeLists.txt | 5 +- 3 files changed, 62 insertions(+), 30 deletions(-) diff --git a/src/lib/dlt_client.c b/src/lib/dlt_client.c index c8a72838c..272c43466 100644 --- a/src/lib/dlt_client.c +++ b/src/lib/dlt_client.c @@ -856,8 +856,8 @@ DltReturnValue dlt_client_send_ctrl_msg_v2(DltClient* client, char* apid, char* msg.baseheaderextrasizev2 = (int32_t)dlt_message_get_extraparameters_size_v2(DLT_CONTROL_MSG);
