Could not find libc about pyinjector

[kmaork]

What process are to trying to inject to? Could you post here its /proc/<pid>/maps?

[auxsvr]

It's pylsp, here is the file maps.txt.

Your environment seems a bit unusual - is it possible /usr/lib64/libc.so.6 is not a symlink on your machine? Please post the output of ls -l /usr/lib64/libc.so.6

[auxsvr]

> ls -l /usr/lib64/libc.so.6
-rwxr-xr-x 1 root root 2,5M Dec 6 00:00 /usr/lib64/libc.so.6

Indeed, it's not a symlink. It's on openSUSE Tumbleweed.

Fixing this requires a change in kubo/injector - https://github.com/kubo/injector/blob/master/src/linux/elf.c#L257 will need to support libc.so.6 (and probably libc.so too) instead of just libc-2.xx.so. I see this issue has surfaced in kubo/injector as well - kubo/injector#15.
Until it is resolved, there is a hacky workaround,
Run:

mkdir /tmp/libc && \
sudo ln /usr/lib64/libc.so.6 /tmp/libc/libc-2.31.so && \
ln -s libc-2.31.so /tmp/libc/libc.so.6 && \
ln -s libc.so.6 /tmp/libc/libc.so

And then run processes you want to inject with LD_LIBRARY_PATH set:

LD_LIBRARY_PATH=/tmp/libc <cmd_to_debug>

[auxsvr]

Ran the above with the difference that I used symbolic links everywhere, as /tmp is a different filesystem, to no avail; the error message is the same.

[kmaork]

The hard link is required, try running it as I posted just in a different directory in the same filesystem.

Kubo has fixed the issue in injector, I released pyinjector==1.0.6 with these changes. Please let me know if it works for you :)

[auxsvr]

The new version works fine, thank you for the prompt response!

[kmaork]

Great to hear, thank you for posting the issue :)
