kernel: set SOURCE_DATE_EPOCH for initramfs root dir

2022-04-06T13:03:58Z

Make sure the timestamp of the root directory of the initramfs is set to SOURCE_DATE_EPOCH as well. Fixes: 29d7461d11 ("kernel: set options to make external initramfs reproducible") Signed-off-by: Daniel Golle (cherry picked from commit 54bcf586b0beb510345fdbac731ce1c04b6fa56b)

kernel: fix initramfs reproducibility

2022-04-06T13:03:58Z

Make sure xz uses at least 2 threads so compression always runs in multi-threaded mode as the resulting file in single-threaded mode differs.

kernel: set options to make external initramfs reproducible

2022-03-27T15:14:00Z

Run cpio as well as compressors in such ways that they are generating reproducible output. Signed-off-by: Daniel Golle (cherry picked from commit 29d7461d1135b91905120a44dc028b786693ecc4)

image: fix CONFIG_EXTERNAL_CPIO handling

2021-11-28T20:15:10Z

CONFIG_EXTERNAL_CPIO is a string variable, hence testing for 'y' doesn't make much sense here. Fixes: 330bd380e8 ("image: allow building FIT and uImage with ramdisk") Reported-by: Huangbin Zhan Signed-off-by: Daniel Golle

build: kernel: avoid unnecessary package rebuilds

2021-11-01T19:18:55Z

The $(LINUX_DIR)/.config timesptamp changes between runs of make target/compile and make target/install (which builds the image). Kernel-dependent packages and out of tree modules are built in between those runs, and they check the .config timestamp to decide if they need to be rebuilt. Save the target/compile .config to use its timestamp if the file does not change between runs. That way the subsequent kernel packages are not unnecessarily rebuilt when you run 'make' back to back.

build: fix regression for kernels < 5.10

2021-05-25T17:46:13Z

This fixes a regression introduced with commit 5ed1e5140a80558ab47fd70410ae3242bed5becf ("build: build kernel image before building modules/packages"). Before this commit the make target would always include "modules", resulting in a MODPOST and a complete Module.symvers file. Since this commit a MODPOST of the kernel modules is not guaranteed for kernels < 5.10. This results in some broken SDKs in which external packages that depend on exported symbols from kernel modules fail to compile. Adding "modules" back to the calls to the CompileImage defines fixes the regression. For kernels > 5.10 this is not needed, but it doesn't cause any harm either. Tested with kernels 5.4.x and 5.10.x.

kernel-defaults: fix external kernel build when user_headers is missing

2021-05-23T13:11:38Z

Use an 'if' so the absence of $(LINUX_DIR)/user_headers doesn't make the line evaluate to false and cause the build to fail. Signed-off-by: Matt Merhar

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

build: use numeric uid/gid on cpio calls

There are systems that don't have the 'root' group, so don't rely on host specific user/group names Signed-off-by: Felix Fietkau
