Available Commands:
help: This help text
info: Show a list of available target profiles
clean: Remove images and temporary build files
image: Build an image (see below for more information).
manifest: Show all package that will be installed into the image
package_whatdepends: Show which packages have a dependency on this
package_depends: Show installation dependency of the package
image:
By default 'make image' will create an image with the default
target profile and package set. You can use the following parameters
to change that:
make image PROFILE="<profilename>" # override the default target profile
make image PACKAGES="<pkg1> [<pkg2> [<pkg3> ...]]" # include extra packages
make image FILES="<path>" # include extra files from <path>
make image BIN_DIR="<path>" # alternative output directory for the images
make image EXTRA_IMAGE_NAME="<string>" # Add this to the output image filename (sanitized)
make image DISABLED_SERVICES="<svc1> [<svc2> [<svc3> ..]]" # Which services in /etc/init.d/ should be disabled
imagebuilder: add package signature verification The ImageBuilder downloads pre-built packages and adds them to images. This process uses `opkg` which has the capability to verify package list signatures via `usign`, as enabled per default on running OpenWrt devices. Until now this was disabled for ImageBuilders because neither the `opkg` keys nor the `opkg-add` script was present during first packagelist update. To harden the ImageBuilder against *drive-by-download-attacks* both keys and verification script are added to the ImageBuilder allowing `opkg` to verify downloaded package indices. This commit adds `opkg-add` to the ImageBuilder scripts folder. The keys folder is added to ImageBuilder $TOPDIR to have an obvious place for users to store their own keys. The `option check_signature` is appended to the repositories.conf file. All of the above only happens if the Buildbot runs with the SIGNATURE_CHECK option. The keys stored in the ImageBuilder keys/ are the same as included in the openwrt-keyring package. To avoid the chicken-egg problem of downloading and verifying a package, containing signing keys, the keys are added during the ImageBuilder generation. They are same as in shipped images (stored at `/etc/opkg/keys/`). To allow a local package feed in which the user can add additional packages, a local set of `usign` and `ucert` keys is generated, same as building OpenWrt from source. The private key signs the local repository inside the packages/ folder. The local public key is added to the keys/ folder to be considered by `opkg` when updating repositories. This way a local package feed can be modified while requiring `opkg` to check signatures for remote feed, making HTTPS optional. The new option `ADD_LOCAL_KEY` allows to add the local key inside the created images, adding the advantage that sysupgrades can validate the ImageBuilders local key.

imagebuilder: add package signature verification The ImageBuilder downloads pre-built packages and adds them to images. This process uses `opkg` which has the capability to verify package list signatures via `usign`, as enabled per default on running OpenWrt devices. Until now this was disabled for ImageBuilders because neither the `opkg` keys nor the `opkg-add` script was present during first packagelist update. To harden the ImageBuilder against *drive-by-download-attacks* both keys and verification script are added to the ImageBuilder allowing `opkg` to verify downloaded package indices. This commit adds `opkg-add` to the ImageBuilder scripts folder. The keys folder is added to ImageBuilder $TOPDIR to have an obvious place for users to store their own keys. The `option check_signature` is appended to the repositories.conf file. All of the above only happens if the Buildbot runs with the SIGNATURE_CHECK option. The keys stored in the ImageBuilder keys/ are the same as included in the openwrt-keyring package. To avoid the chicken-egg problem of downloading and verifying a package, containing signing keys, the keys are added during the ImageBuilder generation. They are same as in shipped images (stored at `/etc/opkg/keys/`). To allow a local package feed in which the user can add additional packages, a local set of `usign` and `ucert` keys is generated, same as building OpenWrt from source. The private key signs the local repository inside the packages/ folder. The local public key is added to the keys/ folder to be considered by `opkg` when updating repositories. This way a local package feed can be modified while requiring `opkg` to check signatures for remote feed, making HTTPS optional. The new option `ADD_LOCAL_KEY` allows to add the local key inside the created images, adding the advantage that sysupgrades can validate the ImageBuilders local key.
