C++. How to trace memory allocation to .so module in linux
https://stackoverflow.com/questions/61083852/c-how-to-trace-memory-allocation-to-so-module-in-linux
Show activity on this post. We are in a situation that have a large application and now there is a situation that would need to know which .so module is allocating how much memory. I have no idea here, I was wondering a custom allocator overriding operator new, but that didn't help because I still cannot trace which module is doing to allocation.

Actually... I also found this article that has some boot-time options (and some more details) for logging kernel memory allocation. Maybe that will do it for you? trace_event=kmem:kmalloc,kmem:kmem_cache_alloc,kmem:kfree,kmem:kmem_cache_free https://elinux.org/Kernel_dynamic_memory_analysis
mtrace(3) - Linux manual page - Michael Kerrisk
https://man7.org/linux/man-pages/man3/mtrace.3.html
The mtrace () function installs hook functions for the memory- allocation functions ( malloc (3), realloc (3) memalign (3) , free (3) ). These hook functions record tracing information about memory allocation and deallocation. The tracing information can be used to discover memory leaks and attempts to free nonallocated memory in a program.
Memory allocation debugging with glibc - Linux.com

Tracing memory allocation calls. Glibc features a tracing functionality for memory allocation debugging. It is enabled by setting a special environment variable and using mtrace () function. The mtrace () function modifies the behavior of malloc functions family by installing hooks for malloc (), realloc () and free () functions, making all the calls to these routines traced and logged.

Tracing the history of memory blocks helps in finding problems related to memory leaks and usage or release of already freed blocks. For this purpose, the GNU C library offers a tracing facility that is enabled by calling the mtrace() function.

Linux provides a variety of APIs for memory allocation. You can allocate small chunks using kmalloc or kmem_cache_alloc families, large virtually contiguous areas using vmalloc and its derivatives, or you can directly request pages from the page allocator with alloc_pages .
