prelink seems to be completly broken and nobody seems to notice it?

I'm not seeing this anywhere.

Perhaps it's because /lib/ld-2.4.so is lib_t rather than ld_so_t on your
system?

Paul.



ls -Z /lib/ld-2.4.so
-rwxr-xr-x root root system_u:object_r:ld_so_t /lib/ld-2.4.so
ls -Z /lib64/ld-2.4.so
-rwxr-xr-x  root     root     system_u:object_r:lib_t
seems that you are correct lets hope that this wont happen again.

this *is* a bug
restorecon /lib64/ld-2.4.so
does not change it to ld_so_t (had to do a chcon)




I did a complete relabel and the result is
ls -Z /lib64/ld-2.4.so
-rwxr-xr-x root root system_u:object_r:lib_t /lib64/ld-2.4.so
I also noticed this:

drwxr-xr-x  root     root     system_u:object_r:var_t          var
looks incorrect too whats going on here?
