Hello,
What suggestions do you have for where I should look next? I'm happy
to start installing various builds of FreeBSD in order to track down
which commit caused this.
I'm trying to access a tape library from within a jail running on a
FreeBSD 11.1 host. sa(4) devices are working (e.g. I can rewind
nsa0).
pass(4) devices (i.e. the tape changer ch0) are not working. This
morning I posted to -scsi@:
https://lists.freebsd.org/pipermail/freebsd-scsi/2017-December/007608.html
The device appears in the jail and has appropriate permissions. This
access was granted
via /etc/devfs.rules using the same approach I used for FreeBSD 10.3
The permissions in the jail:
[root@bacula-sd-02 ~]# ls -l /dev/pass7
crw------- 1 root operator 0x74 Dec 16 21:52 /dev/pass7
The command in the jail:
[root@bacula-sd-02 ~]# mtx -f /dev/pass7 status
cannot open SCSI device '/dev/pass7' - Operation not permitted
Here is the truss output of the command in question:

You don’t by any chance have a securelevel > 1 set for that jail?
