Stephen Smalley ab2cf74685 libselinux: fix selinux_restorecon() statfs bug ... As reported in https://github.com/SELinuxProject/selinux/issues/248, setfiles -r (rootpath) fails when the alternate root contains a symlink that is correct relative to the alternate root but not in the current root. This is a regression introduced by commit e016502c0a ("libselinux: Save digest of all partial matches for directory"). Do not call statfs(2) here if acting on a symbolic link. Unfortunately there is no lstatfs() call. Ensure that we initialize the statfs buffer always. If the supplied file is a symlink, then we don't need to worry about the later tests of filesystem type because we wouldn't be setting the digest anyway and we are not performing a full sysfs relabel. While here, fix the earlier test for a directory to use the correct test. Reproducer: $ mkdir /root/my-chroot && echo foo > /root/my-chroot/link-target && ln -s /link-target /root/my-chroot/symlink $ echo "/root/my-chroot/symlink" | setfiles -vFi -r /root/my-chroot -f - /etc/selinux/targeted/contexts/files/file_contexts Before: setfiles: statfs(/root/my-chroot/symlink) failed: No such file or directory After: Relabeled /root/my-chroot/symlink from unconfined_u:object_r:admin_home_t:s0 to system_u:object_r:default_t:s0 Fixes: https://github.com/SELinuxProject/selinux/issues/248 Fixes: e016502c0a ("libselinux: Save digest of all partial matches for directory") Signed-off-by: Stephen Smalley <stephen.smalley.work@gmail.com> Tested-by: Jonathan Lebon <jlebon@redhat.com> Acked-by: Petr Lautrbach <plautrba@redhat.com>		2020-06-18 19:25:27 +02:00
