A new script beside the image recipe, run by both images as the last
rootfs step (ROOTFS_POSTPROCESS_COMMAND:append, after every +=, the dev
recipe's and debug-tweaks' included); a refusal is bbfatal. It checks
every rule and prints every failure before it exits. FORGEFIRM_IMAGE_KIND
(release by default, dev in forgefirm-image-dev.bb) picks the sshd policy.
The rules:
- syslog: /usr/sbin/rsyslogd is on the image, /etc/init.d/syslog starts
it and runlevel 5 starts that script; no syslogd or klogd is linked in
a bin directory and no init script runs one. This is the image half of
what logs.routing checked on the board; that test left in 01f5991 with
nothing else holding it.
- sshd: sshd_config and sshd_config_readonly take passwords
(PasswordAuthentication yes) and send no banner; on a release image
PermitRootLogin no and PermitEmptyPasswords no; sshd_config.d sets none
of the four, since an included value comes first. setup.ssh-until-
reboot checked the first two on the board and left in 01f5991;
release.sh gates the release pair at release time only.
- dhcp-name: the wlan0 dhcp stanza's udhcpc_opts carries
-x hostname:$(hostname).
- mdns: no /etc/avahi, avahi-daemon or libnss_mdns, and no mdns source
on nsswitch.conf's hosts line.
dhcp-name and mdns are the image half of setup.machine-name, whose
scripts test_image.py's MachineNameTests already run.
test_image.py's RootfsLintTests run it on a fixture tree: the tree that
holds every rule passes as either image, the BSP layer's own interfaces
file passes, and one drift per rule fails naming the rule (a busybox
syslogd link; a Banner, on either image; root and an empty password,
refused on a release image and passed on a dev one; a dhcp stanza with
no name; /etc/avahi).
Proof: test_image.py under Linux, 21 OK; pyflakes clean. On image
20261015134521's two rootfs trees from the build, the release tree
passes as release, the dev tree passes as dev, and the dev tree linted
as release is refused on PermitRootLogin and PermitEmptyPasswords in
both sshd files. bitbake -e places rootfs_lint last in both images'
ROOTFS_POSTPROCESS_COMMAND, with FORGEFIRM_IMAGE_KIND release and dev.
The layer content hash moves: the next image cannot inherit a campaign.
