Package: libeatmydata1
Version: 82-6
Severity: normal
Dear Maintainer,
Please consider installing /usr/lib/x86_64-linux-gnu/libeatmydata.so.1.1.2
with the setuid bit set. Without that, executing some commands (like
fusermount) in eatmydata-enabled chroots give weird error messages like:
$ fusermount -u sshfs_mountpoint
ERROR: ld.so: object 'libeatmydata.so' from LD_PRELOAD cannot be preloaded
(cannot open shared object file): ignored.
$
..yet the command also succeeds.
This is because (from ld.so(8)):
LD_PRELOAD
A list of additional, user-specified, ELF shared libraries to be
loaded before all others. The
items of the list can be separated by spaces or colons. This can
be used to selectively over‐
ride functions in other shared libraries. The libraries are
searched for using the rules given
under DESCRIPTION. For set-user-ID/set-group-ID ELF binaries,
preload pathnames containing
slashes are ignored, and libraries in the standard search
directories are loaded only if the
set-user-ID permission bit is enabled on the library file.
Thanks!
-Nikolaus
