Libmallocjack

This is a work in progress, it was barely tested only on glibc-2.27 and still lacks thread-safeness.

Compilation

To compile the library run make. To run the tests make run. Remember to compile the code you want to debug with -rdynamic and -funwind-tables, besides naturally your basic debugging options. When not compiled with the last two compilation flags though you won't get string symbols for functions.

Built-in modules

memstat

Print overall process and function statistics.

memlimit

Limit memory usage by process and function.

Todo

• [#a] enable thread-safeness everywhere
• [#a] use mmap in local_alloc and support free
• [#b] port memstat to gnu malloc info api
• [#b] detect huge page, segregation and brk/mmap
• [#b] allow dlopen() specific targets
• [#c] check malloc_usable_size() consistency
• [#c] add strace-like debugging primitives
• [#c] add ltrace-like debugging primitives
