image: always rebuild kernel loaders

2022-10-14T21:15:30Z

Kernel loaders like the lzma-loader currently don't track changes to their sources. This can lead to an old version of a loader to be used when a build tree is not clean between builds. As the loaders are tiny and the build times are insignificant, simply force rebuilding them on every build to avoid this problem.

build: store sha256_unsigned in JSON

2022-04-06T13:03:58Z

Introduce `sha256_unsigned` which is a checksum of the image _before_ a signature is attached. This is helpful to compare image reproducibility. Since the `.sha256sum` file is located in the $(KDIR) folder, switch $(BIN_DIR) with $(KDIR) to simplify the code. The value of $(BIN_DIR) itself is not stored inside the resulting JSON file, so it can be replaced. Signed-off-by: Paul Spooren (cherry picked from commit 8822a8d850ba2df69b81289758959bb90643a696)

image: let mksquashfs4 use all processors

2022-04-06T13:03:58Z

Drop the -processors argument from the mksquashfs4 call, so it will use all available processors. This dramatically reduces the time to create squashfs filesystems. The times below are observed when building an image for my main router, the WatchGuard Firebox M300 (qoriq target): Before: real 4m45,973s After: real 0m23,497s With this commit `mksquashfs` may use more cores than defined via `-j`. This is the same behaviour as for archive creation of ImageBuilder, SDK or toolchain. There is no trivial way to limit `mksquashfs` CPU core usage to the amount of "free" make jobs since two running `mksquashfs` instances would each run with the total allowed number (-j) of threads.

image: define DEVICE_DTS_DELIMITER as per-device variable

2021-10-24T09:19:58Z

DEVICE_DTS_DELIMITER needs to be in the DEFAULT_DEVICE_VARS list to work as expected. This was missing from the original version and got overlooked. Fixes: fd6790864739 ("scripts: mkits.sh: Allow legacy @ mode for dts creation") Signed-off-by: Christian Lamparter

build: store artifacts in JSON

2021-09-14T20:42:38Z

Multiple profiles create artifacts, these should be stored in the JSON file as well, allowing downstream tooling to show those files, too. Artifacts don't have specific filesystems so only the fields `name`, `type` and `sha256` are available. Rename env variable names from IMAGE_ to FILE_ prefixes to reflect that images, kernels and artifacts are added with the same command. Signed-off-by: Paul Spooren

image: fix build with SELinux

2021-08-19T00:37:35Z

The option '-xattr' for mksquashfs4 should be '-xattrs' which lead to build failure with SELinux enabled. Add the missing 's'. Fixes: 4baf47b9a8 ("images: squashfs: xattrs should not depend on buld host") Signed-off-by: Daniel Golle

images: squashfs: xattrs should not depend on buld host

2021-08-03T17:28:53Z

Enable xattr for the generated squashfs only if needed for SELinux. This eliminates warnings during boot on target when building (non-SELinux) OpenWrt on SELinux-enabled hosts like Fedora. Reported-by: fda77 Signed-off-by: Daniel Golle

build: fix build for devices without initramfs

2021-06-08T20:53:14Z

Don't attempt to copy initramfs images for devices which do not output an initramfs image. This was breaking builds for mpc85xx-p1010 since mid-march. Signed-off-by: David Bauer

build/json: fix DEVICE_PACKAGES

2021-06-02T20:58:13Z

The variable was missing in the definition of DEFAULT_DEVICE_VARS which caused it to contain wrong values, messing up the resulting JSON files. This patch adds the variable DEVICE_PACKAGES to DEFAULT_DEVICE_VARS. Suggested-by: Baptiste Jonglez Signed-off-by: Paul Spooren

build: introduce $(MKHASH)

2021-05-13T13:13:15Z

Before this commit, it was assumed that mkhash is in the PATH. While this was fine for the normal build workflow, this led to some issues if make TOPDIR="$(pwd)" -C "$pkgdir" compile was called manually. In most of the cases, I just saw warnings like this: make: Entering directory '/home/.../package/gluon-status-page' bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found bash: line 1: mkhash: command not found [...] While these were only warnings and the package still compiled sucessfully, I also observed that some package even fail to build because of this. After applying this commit, the variable $(MKHASH) is introduced. This variable points to $(STAGING_DIR_HOST)/bin/mkhash, which is always the correct path. Signed-off-by: Leonardo Mörlein
