selinux_child does not call rmdir itself. it just uses libsemange and libsemanage seems to call rmdir sh# objdump -T /usr/libexec/sssd/selinux_child | grep rmdir sh# objdump -p /usr/libexec/sssd/selinux_child | grep semanage NEEDED libsemanage.so.1 required from libsemanage.so.1: sh# objdump -T /usr/lib64/libsemanage.so | grep rmdir 0000000000000000 DF *UND* 0000000000000000 GLIBC_2.2.5 rmdir It seems to be a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=1368097 which is supposed to be fixed in selinux-policy-3.13.1-97.el7 |
