From 4016e8fdaa5735c328e274777154b1a3de6838a6 Mon Sep 17 00:00:00 2001 From: doomedraven Date: Mon, 17 Aug 2026 13:33:16 +0200 Subject: [PATCH 1/7] Optimize concurrent logging via decoupled thread-local serialization (SBO-Decoupling) Implements completely concurrent and thread-local log serialization inside loq. Makes g_bson and g_istr thread-local variables using __declspec(thread), allowing multiple monitored threads to format their API arguments lock-free. Holds the global g_mutex strictly during the actual BSON buffer flush/cache operations, dropping lock-hold times from milliseconds to microseconds. --- log.c | 95 +++++++++++++++++++++++++++++++++++++---------------------- 1 file changed, 59 insertions(+), 36 deletions(-) diff --git a/log.c b/log.c index 69943099..d97f3545 100644 --- a/log.c +++ b/log.c @@ -52,8 +52,8 @@ static BOOLEAN delete_last_log; HANDLE g_log_handle; // current to-be-logged API call -static bson g_bson[1]; -static char g_istr[4]; +__declspec(thread) static bson g_bson[1]; +__declspec(thread) static char g_istr[4]; static char logtbl_explained[256] = {0}; @@ -559,40 +559,31 @@ void loq(int index, const char *category, const char *name, hook_disable(); - { - int retries = 100; - BOOL acquired = FALSE; + if (logtbl_explained[index] == 0) { + const char * pname; + bson b[1]; - while (retries-- > 0) { - if (TryEnterCriticalSection(&g_mutex)) { - acquired = TRUE; - break; - } - SwitchToThread(); - } + { + int retries = 100; + BOOL acquired = FALSE; - if (!acquired) { - goto exit; - } - } + while (retries-- > 0) { + if (TryEnterCriticalSection(&g_mutex)) { + acquired = TRUE; + break; + } + SwitchToThread(); + } - if (!special_api_triggered) - last_api_logged = API_OTHER; - else { - special_api_triggered = FALSE; - if (delete_last_log) { - free(lastlog.buf); - lastlog.buf = NULL; + if (!acquired) { + goto skip_explain; + } } - } - - if (logtbl_explained[index] == 0) { - const char * pname; - bson b[1]; - logtbl_explained[index] = 1; + if (logtbl_explained[index] == 0) { + logtbl_explained[index] = 1; - va_start(args, fmt); + va_start(args, fmt); bson_init( b ); bson_append_int( b, "I", index ); @@ -723,12 +714,16 @@ void loq(int index, const char *category, const char *name, } } - bson_append_finish_array( b ); - bson_finish( b ); - log_raw_direct(bson_data( b ), bson_size( b )); - bson_destroy( b ); - // log_flush(); - va_end(args); + bson_append_finish_array( b ); + bson_finish( b ); + log_raw_direct(bson_data( b ), bson_size( b )); + bson_destroy( b ); + // log_flush(); + va_end(args); + } + LeaveCriticalSection(&g_mutex); +skip_explain: + ; } fmt = fmtbak; @@ -1133,6 +1128,34 @@ void loq(int index, const char *category, const char *name, bson_append_finish_array( g_bson ); bson_finish( g_bson ); + { + int retries = 100; + BOOL acquired = FALSE; + + while (retries-- > 0) { + if (TryEnterCriticalSection(&g_mutex)) { + acquired = TRUE; + break; + } + SwitchToThread(); + } + + if (!acquired) { + bson_destroy( g_bson ); + goto exit; + } + } + + if (!special_api_triggered) + last_api_logged = API_OTHER; + else { + special_api_triggered = FALSE; + if (delete_last_log) { + free(lastlog.buf); + lastlog.buf = NULL; + } + } + if (index == LOG_ID_PROCESS || index == LOG_ID_THREAD || index == LOG_ID_ENVIRON) { // don't hold back any of our critical notifications -- these *must* be flushed in log_init() log_raw_direct(bson_data(g_bson), bson_size(g_bson)); From a3ce87ad9b338e87ad2676f96bc79ac6509d0873 Mon Sep 17 00:00:00 2001 From: doomedraven Date: Tue, 18 Aug 2026 12:50:19 +0200 Subject: [PATCH 2/7] Fix static TLS crashes inside injected processes (decoupled-logging-v2 Fix) Surgically fixes the fatal crash bug caused by illegal static TLS usage (__declspec(thread)) inside the dynamically injected capemon.dll: 1. Replaces the unsupported static TLS variables g_bson and g_istr with safe, dynamic Windows Thread Local Storage (TLS) API (TlsAlloc, TlsGetValue, TlsSetValue, TlsFree). 2. Maps g_bson and g_istr through preprocessor macros to dynamic, auto-allocated thread contexts (thread_log_context_t) on-the-fly, retaining 100% compatibility with all 50+ logging helper functions. 3.

NULL Pointer Dereference Protection: - Added null check when calloc() fails in GetThreadLogContext() - Added null-safe accessor macros for g_bson and g_istr - Added early TLS validation in loq() before any logging operations - Prevents crashes when TLS allocation fails 2. Race Condition Fix in logtbl_explained: - Fixed broken double-checked locking with volatile cast - Added proper memory ordering: *(volatile char*)&logtbl_explained[index] - Replaced unsafe goto skip_explain with early return + cleanup - Ensures thread-safe initialization of log table explanations 3.
