2021-11-04Prepare master for new framework integrationJan-Simon Moeller1-14/+1
During the last workshop the transition to the new framework was presented. This change essentially deprecates the SMACK-based application framework. To prepare the integration of it, we remove the deprecated components: - meta-agl-core: remove Smack kernel patches - meta-app-framework - meta-pipewire/dynamic-layers/meta-app-framework/ v2: rebased Bug-AGL: SPEC-4121 Signed-off-by: Jan-Simon Moeller <jsmoeller@linuxfoundation.org> Change-Id: Icdaeadfb5d2193f3a4c535168c88da6073423e67 Reviewed-on: https://gerrit.automotivelinux.org/gerrit/c/AGL/meta-agl/+/26752

2019-10-23meta-netboot: don't use 'ip' command to detect boot interfaceStephane Desneux1-3/+29
This patch changes the method to detect the current network interface used for netboot. Instead of using the 'ip' command, it parses the content of /sys/class/net/* to detect the first running ethernet interface. Two new messages are now visible on the console in initramfs phase: -------------------------------------------------- /sbin/init[1]: find_active_interface: first active interface is eth0 /sbin/init[1]: Adjusting Connman command line. Will be: 'connmand -r -n -I eth0' -------------------------------------------------- Background: When booting using netboot, it's necessary to update connman command line options to ignore the network interface used for NBD connection. For this, the initramfs script tries to detect the interface in use by running 'ip -o link show state'. 'ip' command comes with iproute2 package but for various reasons, some AGL images like m3ulcb-nogfx don't have iproute2 installed. In this case, the 'ip' command is implemented by busybox, which doesn't support the '-o' option. This leads to issues when running connman as the command line is not properly updated.

2019-07-12netboot: adjust SMACK label for /etc/resolv.confStephane Desneux1-0/+1
When using netboot, the kernel is responsible for establishing the IP connection. For this reason, connman is instructed to "forget" this boot interface and /etc/resolv.conf is generated by the initrd script (from /proc/net/pnp). This patch removes the previously set SMACK label 'System' so file has label _, which makes it readable by any process.

2019-07-07netboot: systemd must mount /tmp and /runStephane Desneux1-2/+8
When using netboot, the initrd script mounts /tmp and /run before pivoting on the new rootfs and then running systemd. As a consequence, systemd doesn't try to remount /tmp or /run (and the correct smack labels are not applied on /tmp and /run, leading to many issues). This patch unmounts /tmp and /run just before running systemd which will then mount them with correct labels.

Add a new cmdline argument using option 'nbd.v3' that could be parsed by the initrd script used for netboot. Bug-AGL: SPEC-1423 Change-Id: I1cd189c343672631feda5bcee2e393eb46b9d000 Signed-off-by: Ronan Le Martret <ronan.lemartret@iot.bzh>

2016-05-29add layer meta-netboot to enable network boot over NBD (Network Block Device)Stephane Desneux1-0/+149
To enable the build of network bootable images, the following line must be added to conf/local.conf: INHERIT += "netboot" This layer contains recipes for the following components: * busybox: activate the built-in NBD client * initramfs-netboot: contains the init script started by the kernel, responsible for mounting the remote root filesystem then pivoting and exec'ing systemd * initramfs-netboot-image: image to specify for building the initrd More details are available in meta-netboot/README.
