It seems that LD_* variables are selectively ignored by ld.so. The command above results in: $ LD_LIBRARY_PATH=/usr/lib64/libfakeroot LD_PRELOAD=libfakeroot-sysv.so /lib/ld-kfreebsd-x86-64.so.1 /bin/true ERROR: ld.so: object 'libfakeroot-sysv.so' from LD_PRELOAD cannot be preloaded: ignored. $ On a sane system you'd get the same message if LD_LIBRARY_PATH was not set. Another example: $ LD_SHOW_AUXV=yes /lib/ld-kfreebsd-x86-64.so.1 /bin/true $ In this example, LD_PRELOAD has been ignored completely (ktrace confirms this): $ LD_PRELOAD=/usr/lib64/libfakeroot/libfakeroot-sysv.so /lib/ld-kfreebsd-x86-64.so.1 /usr/bin/id -u 1000 $ However, depending on its content it is processed. Example with an invalid file name: $ LD_PRELOAD=foobar /lib/ld-kfreebsd-x86-64.so.1 /bin/true ERROR: ld.so: object 'foobar' from LD_PRELOAD cannot be preloaded: ignored. $ Another invalid file name. This time it is ignored: $ LD_PRELOAD=foo/bar /lib/ld-kfreebsd-x86-64.so.1 /bin/true $ As for LD_SHOW_AUXV=yes, I tried different combinations and it is always ignored, no matter what. -- Robert Millan -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
