GrapheneOS / hardened_malloc

Hardened allocator designed for modern systems. It has integration into Android's Bionic libc and can be used externally with musl and glibc as a dynamic library for use on other Linux-based platforms. It will gain more portability / integration over time.

[linux, question] Error loading shared libraries #207

Closed dkwo closed 1 year ago

dkwo commented 1 year ago

This is most likely a mistake on my end. On Void Linux (x86_64-musl) I tried to package hardened-malloc https://github.com/void-linux/void-packages/compare/master...dkwo:void-packages:stinger If I put /usr/lib/libhardened_malloc.so in /etc/ld-musl-x86_64.path, then most commands from coreutils fail to work, for example ls gives

Error loading shared library libcap.so.2: No such file or directory (needed by /bin/ls)
Error relocating /bin/ls: cap_to_text: symbol not found
Error relocating /bin/ls: cap_free: symbol not found
Error relocating /bin/ls: cap_get_file: symbol not found

If instead I use LD_PRELOAD, it works fine.

Do you see what I'm doing wrong?

That's not the right place to configure it. You're overriding the default library search path so libraries can't be found.

Thank you! I'm now using

$ cat /etc/ld.so.preload 
/usr/lib/libhardened_malloc.so
