Hello all,
I am trying to test chroot on a Raspberry Pi running the distro-provided
Freeradius 3.0.21 on the 32bit Raspberry Pi OS (Debian) 11.
According to the instructions from networkradius.com and freeradius -X
error messages, I created the chroot folder hierarchy and the required
files as shown below:
The character devices null, zero, random and urandom were created under
/var/freeradius/chroot/dev.
/var/freeradius/chroot/etc/ssl/certs
/var/freeradius/chroot/etc/ssl/certs/private
/var/freeradius/chroot/etc/passwd
/var/freeradius/chroot/var/run
The following folders and files are bind mounted in the chroot:
/var/freeradius/chroot/usr/lib/freeradius/
/var/freeradius/chroot/usr/lib/arm-linux-gnueabihf/
/var/freeradius/chroot/etc/freeradius/3.0/certs/
/var/freeradius/chroot/etc/freeradius/3.0/mods-config/
/var/freeradius/chroot/etc/nsswitch.conf
/var/freeradius/chroot/etc/resolv.conf
/var/freeradius/chroot/var/log/freeradius/
The ownership and permission bits for all files and folders in the
chroot folder are the same as their non-chrooted counterparts.
Finally, I enabled chroot in radiusd.conf.
Running freeradius -X, the debug output seems to be *exactly* the same
as running freeradius -X with chroot disabled (well, only the line
chroot = "/var/freeradius/chroot" was added in the security {} block
output). While running the chrooted Freeradius as freeradius -X,
Freeradius performs client authentication with EAP-PEAP and EAP-(T)TLS,
proxing, etc normally. If -P is provided (freeradius -XP), the PID file
is created in the /var/freeradius/chroot/var/run/ as expected. The
output of freeradius -X with chroot enabled is given below:

---------------End of journalctl -xe output--------------------
Although I am not a Systemd or a Freeradius guru, I made a simple
investigation with the following results:
1) The provided systemd script contains the following lines:
ExecStartPre=/usr/sbin/freeradius $FREERADIUS_OPTIONS -Cx -lstdout
ExecStart=/usr/sbin/freeradius -f $FREERADIUS_OPTIONS
The variable $FREERADIUS_OPTIONS populated in /etc/default/freeradius is
set to an empty string ("") - the provided default value.
2) The command in ExecStartPre (/usr/sbin/freeradius -Cx -lstdout)
always returns with the message "Configuration appears to be OK".
3) If I run freeradius -f -lstdout (as shown above in ExecStart) from
the command line, I am getting the following output depending on the
user I am logged in:
a) As 'root' *regardless if chroot is enabled or not* or as 'freerad'
(the Freeradius user in Debian) *with chroot disabled*, the output is:
----------freeradius -f -lstdout output---------------------

b) As 'freerad' *with chroot enabled*, freeradius -f -lstdout returns
immediately without reporting or logging any error(s):
----------freeradius -f -lstdout output---------------------

----------End of freeradius -f -lstdout output--------------
Is this a permission problem or am I doing something wrong?
Thank you in advance,
Antonios
