Script for the preparation of binary files for execution with non-system glibc

[fr0ster]

Hi everybody I try used how2heap but got troubles with building old libc on my system. Before I just download needed version of libc and set rpath and interpreter by patchelf, so I wrote script that download glibc, extract into folder and set rpath/interpreter for target binary. As additional ability I added keys for execution over gdb/radare2.

I hope it will be useful as additional features of yours project :)

I appreciate the help in extending how2heap. The goal of this patch is to allow users to debug old/new heap mechanisms by building another glibc. And I believe this is an important feature. There is one thing I don't understand though: what's the difference between this patch and existing glibc_build.sh and glibc_run.sh scripts? I think both build the target libc version and run programs with the libc.

Sometime glibc_build works uncorrect and cant build needed version glibc. This patch just give ability download glibc from internet. Script glibc_run work after successful execution glib_build only.

I think currently the pull request is bloated. It even has compiled binaries in it. Can you please clean up the pull request?

Sometime glibc_build works uncorrect and cant build needed version glibc.

Can you please give an example here? Maybe we can fix it in glibc_build. If it cannot be fixed, then we can replace it with the pull request.

I try build glibc for 2.34 and

I think about using docker for building and debugging binaties with non-system glibc.

[Kyle-Kyle]

I just fixed the glibc_build/glibc_run scripts. The branch is here: https://github.com/shellphish/how2heap/commit/20feb34b16fbe870253ec3f403ec2365dbd1cdd8

Can you please check whether it works?

After playing with both glibc_build and the PR. I believe this PR is better than the existing framework. Since glibc_build/glibc_run has the same purpose as this PR and they are broken. I think it is better to just replace them with this PR (basically, mv prepared_binary.sh glibc_run.sh). And please try to initialize the submodule in the beginning of the script as well. Thanks!

Should I make new PR or I cat just add new commit in this PR?

[fr0ster]

I renamed prepared_binary.sh to glibc_run.sh and renabe option for GDB debugging from -g to -gdb

[Kyle-Kyle]

the PR looks awesome now! Thanks!
