On systems such as Arch Linux, all programs which are usually located in
/bin, /sbin, /usr/bin and /usr/sbin are present in /usr/bin and the
other locations are symbolic links to this directory. With such a
configuration, the file contexts which define types for files in
/bin, /sbin and /usr/sbin need to be duplicated to provide definitions
for /usr/bin/...
As the "/bin vs. /usr/bin" part of the needed definitions has already
been done with the "usr merge" patches, the next step consists in
duplicating file contexts for /usr/sbin. This is what this patch does
for all modules which are not in contrib.
This is the second iteration of an idea I have previously posted on
http://oss.tresys.com/pipermail/refpolicy/2017-March/009176.html
Remove file context aliases and update file context paths to use the /run filesystem path.
Add backward compatibility file context alias for /var/run using applications like https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=783321
Lock files are still seated at /var/lock
On Arch Linux, OpenSSH unit files are:
/usr/lib/systemd/system/sshdgenkeys.service
/usr/lib/systemd/system/sshd.service
/usr/lib/systemd/system/sshd@.service
/usr/lib/systemd/system/sshd.socket
On Debian jessie, the unit files are:
/lib/systemd/system/ssh.service
/lib/systemd/system/ssh@.service
/lib/systemd/system/ssh.socket
On Fedora 22, the unit files are:
/usr/lib/systemd/system/sshd-keygen.service
/usr/lib/systemd/system/sshd.service
/usr/lib/systemd/system/sshd@.service
/usr/lib/systemd/system/sshd.socket
Use a pattern which matches every sshd unit and introduce an other type
for ssh-keygen units.
On Arch Linux, OpenSSH installs these binary files in /usr/lib/ssh:
* sftp-server (labeled with ssh_keysign_exec_t type in refpolicy)
* ssh-askpass (symlink to x11-ssh-askpass)
* ssh-keysign
* ssh-pkcs11-helper
* x11-ssh-askpass (from x11-ssh-askpass package)
Label all these files but sftp-server as bin_t.
Also allow sshd_t domain to chroot(2) in this directory as explained in
the README.privsep file in the openssh tarball.
