Hi all,
According to the man page of "ulimit", it is possible to limit the virtual address space of a user process: https://ss64.com/bash/ulimit.html
To limit the virtual address space to 2 GB:
$ ulimit -SH -v 1048576
However, it seems that "stack" allocation ignores this limit (I tried with both kernel 4.4 and 4.15).
I found this article (patch) that seems to fix the problem:
My questions are:
- Why is the stack allocation not placed within the "ulimit" limit? (is it a bug?)
- Is there a way, in user space, to force the stack to be allocated at a certain address?
- Will the patch above (or similar) ever be integrated into the Linux kernel?
Regards,
Mohamed
