I created https://github.com/catskul/tizen-heaptrack to make comparison, PRs,
and forking easier. I'll take a look later to see if there's any twidling I
need to do to make it share history with

@Pash: do you mean samsung/tizen has forked heaptrack? cool! can you refer me
to their code repo? First time I hear about that.

nvm that, I forgot to init the mmap hook, it all seems to work fine actually!
thanks a lot for bringing this to my attention, I'm seriously wondering why I
never tried this out so far.

Hm yes indeed, I just tested it and I can really intercept it - awesome! I'll
definitely want to add that in the future then. I'm not yet sure how to do this
properly though, as intercepting mmap may still need some

There's no mmap symbol in the VDSO. mmap in libc is a wrapper that makes a
syscall through the VDSO or directly on some architectures, so you can
intercept it.

but the mmap symbol in libc is just a shim that gets replaced by a symbol from
the vdso, no? and afaik you cannot intercept these via LD_PRELOAD - or am I
mistaken?

LD_PRELOAD would work at least in my case, since I call mmap through the C
library. For times when this doesn't work, intercepting mmap with ptrace is
possible, and not all that hard.

syscalls like mmap cannot be easily intercepted with LD_PRELOAD or similar,
which makes it quasi impossible to do with the current architecture of
heaptrack.
thankfully, you can easily use perf to achieve the same,
