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>
2018-02-22Hotfix for db410 on rockoJan-Simon Möller1-1/+4
The db410c build uses IMAGE_FSTYPES_append which is a bad idea and should be changed to IMAGE_FSTYPES ?= Anyway - add a hotfix directly in the recipes. Change-Id: I163e4fdccfc890085cf98571dcf5d7bf21cffadd Signed-off-by: Jan-Simon Möller <jsmoeller@linuxfoundation.org>
2017-06-28Fix rpi-sdimg after IMAGE_FSTYPE being enforced in poky-agl.confJan-Simon Möller1-1/+1
This changeset fixes the case of the rpi-sdimg which was broken by the IMAGE_FSTYPE setting introduced in poky-agl.conf (distro-wide). A new variable AGL_EXTRA_IMAGE_FSTYPES is available now and only used in AGL (target) images. Reasoning for this solution: - any modifications to IMAGE_FSTYPES will also affect things like the initramfs or initrd images. - we minimized the disk-space requirements by reusing the ext4.xz for the rpi-sdimg Bug-AGL: SPEC-492 Change-Id: I07fd51dbcf334653cd6033b7ccb663c4d4ed8578 Signed-off-by: Jan-Simon Möller <jsmoeller@linuxfoundation.org> Reviewed-on: https://gerrit.automotivelinux.org/gerrit/9887 Tested-by: Jenkins Job builder account <agl-jobbuilder@automotivelinux.org> ci-image-build: Jenkins Job builder account <agl-jobbuilder@automotivelinux.org>
2017-06-23meta-agl-netboot: increase IMAGE_ROOTFS_EXTRA_SPACEStephane Desneux1-0/+1
More room is needed when installing debug packages or big components like Chromium. Also, IMAGE_ROOTFS_EXTRA_SPACE was overridden by another unidentified configuration file or recipe: the setting is now forced. Consequently, the extra space must be reduced specifically for initrd.

2016-05-29add layer meta-netboot to enable network boot over NBD (Network Block Device)Stephane Desneux5-0/+194
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.
