Subject: [PATCH] dracut-install: simplify ldd parsing logic
|
|
|
737328c |
|
|
|
737328c |
The previous logic would not handle absolute paths on the left side of
|
|
|
737328c |
the "=>" properly. For example, on Gentoo ARM64, ldd outputs this:
|
|
|
737328c |
|
|
|
737328c |
/lib/ld-linux-aarch64.so.1 => /lib64/ld-linux-aarch64.so.1
|
|
|
737328c |
|
|
|
737328c |
At runtime, the kernel tries to load the file from /lib, and fails if we
|
|
|
737328c |
only provide it in /lib64.
|
|
|
737328c |
|
|
|
737328c |
Instead of looking for the first slash after the "=>", just look for the
|
|
|
737328c |
first slash, period. This would fail if we somehow had a relative path
|
|
|
737328c |
on the left side (foo/libbar.so), but I'm not aware of any binaries that
|
|
|
737328c |
would contain such an entry in DT_NEEDED.
