0d9799de04 Don't test for NULL before calling free(3)
free(3) accepts NULL, since the oldest ISO C.  I guess the
paranoid code was taking care of prehistoric implementations of
free(3).  I've never known of an implementation that doesn't
conform to this, so let's simplify this.

Remove xfree(3), which was effectively an equivalent of free(3).

cde221b858 copy_tree: carefully treat permissions
The setuid, setgid, and sticky bits are not copied during copy_tree.

Also start with very restrictive permissions before setting ownerships.

This prevents situations in which users in a group with less permissions
than others could win a race in opening the file before permissions are
removed again.

Proof of concept:

$ echo $HOME
/home/uwu
$ install -o uwu -g fandom -m 604 /dev/null /home/uwu/owo
$ ls -l /home/uwu/owo
-rw----r-- 1 uwu fandom 0 Sep  4 00:00 /home/uwu/owo

If /tmp is on another filesystem, then "usermod -md /tmp/uwu uwu" leads
to this temporary situation:

$ ls -l /tmp/uwu/owo
-rw----r-- 1 root root  0 Sep  4 00:00 /tmp/uwu/owo

This means that between openat and chownat_if_needed a user of group
fandom could open /tmp/uwu/owo and read the content when it is finally
written into the file.

10cd68e0f0 copy_tree: do not block on fifos
Fixes regression introduced in faeab50e71.

If a directory contains fifos, then openat blocks until the other side
of the fifo is connected as well.

This means that users can prevent "usermod -m" from completing if their
home directories contain at least one fifo.

faeab50e71 Avoid races in copy_tree()
Use *at() functions to pin the directory operating in to avoid being
redirected by unprivileged users replacing parts of paths by symlinks to
privileged files.

Introduce a path_info struct with the full path and dirfd and name
information for *at() functions, since the full path is needed for link
resolution, SELinux label lookup and ACL attributes.

2b22a6909d libsubid: don't print error messages on stderr by default
Closes #325

Add a new subid_init() function which can be used to specify the
stream on which error messages should be printed.  (If you want to
get fancy you can redirect that to memory :)  If subid_init() is
not called, use stderr.  If NULL is passed, then /dev/null will
be used.

This patch also fixes up the 'Prog', which previously had to be
defined by any program linking against libsubid.  Now, by default
in libsubid it will show (subid).  Once subid_init() is called,
it will use the first variable passed to subid_init().

eb1d2de0e9 set_selinux_file_context(): prepare context for actual file type
Search the SELinux selabel database for the file type to be created.
Not specifying the file mode can cause an incorrect file context to be
returned.

Also prepare contexts in commonio_close() for the generic database
filename, not with the backup suffix appended, to ensure the desired
file context after the final rename.
