build system: have tar use $SOURCE_DATE_EPOCH for --mtime

2016-01-31T23:29:16Z

The --mtime argument to 'tar' sets the modification time for all files within the archive, which determines the timestamp files will get when they are extracted. In this case, rootfs and other tarballs will get mtimes which correspond to the last commit timestamp of the build system, as reported by git/subversion. This is a step towards reproducible image builds. Signed-off-by: bryan newbold Signed-off-by: Alexander Couzens Signed-off-by: Felix Fietkau SVN-Revision: 48586

kernel-build: fix STRIP_KERNEL_EXPORTS for recent kernels

2014-09-15T16:18:48Z

Recent kernels started to mark exported symbols as global. Adapt expressions in kernel-build.mk to also match global symbols when grep'ing through nm output. Signed-off-by: Daniel Golle SVN-Revision: 42555

include: fix kernel download failure with git & local trees

2014-06-02T12:43:13Z

When using the options EXTERNAL_KERNEL_TREE or KERNEL_GIT_CLONE_URI, the command "make downloads" fails as it tries to download the kernel tarball despite the option. This doesn't happen during a regular build as in that case, the dependency is conditionned through the LINUX_SITE variable, which is not set in these cases. Below is a snapshot of the error for an target using a 3.14 kernel: make[3]: *** No rule to make target `.../dl/linux-3.14.tar.xz', needed by `download'. Stop.

build: speed up kernel symbol export stripping

2013-12-14T13:14:44Z

GNU grep has a high per-expression setup overhead when compiling regular expressions. Use -F to force it to interpret the input as fixed strings, which is much faster (fraction of a second instead of multiple minutes). Signed-off-by: Felix Fietkau SVN-Revision: 39049

buildroot: build a second pass kernel if initramfs is enabled

If initramfs is enabled, build a second pass kernel containing the CPIO rootfs, preliminary work to get non exclusive enabling of initramfs. Signed-off-by: Florian Fainelli SVN-Revision: 37047
