* kernel: prevent adding custom string to localversionJosua Mayer2016-08-181-0/+1
| | | | | | | | | When the kernel build picks up a localversion file in the source tree, that string is unconditionally appended to LOCALVERSION and affects the uname string. Make sure to delete any such file. Signed-off-by: Josua Mayer <josua.mayer97@gmail.com>
* kernel: prevent addition of scm marker to localversionJosua Mayer2016-08-181-0/+4
| | | | | | | | | When building the kernel from a git repository, the kernel build appends either a + or a short commit hash to localversion. This behaviour can be prevented by passing the empty LOCALVERSION variable to make. Signed-off-by: Josua Mayer <josua.mayer97@gmail.com>
* kernel: check SOURCE_DATE_EPOCH before setting KBUILD_BUILD_TIMESTAMPJonas Gorski2016-08-131-1/+1

* kernel: allow reproducable buildsJonas Gorski2016-08-131-0/+2
| | | | | | | | | | | | Similar how we fix the file times in the filesystems, fix the build time of the kernel, and make the build number static. This should allow the kernel build to be reproducable when combined with setting the KERNEL_BUILD_USER and _DOMAIN in case of different machines. The reproducability only applies to non-initramfs kernels, those still require additional changes. Signed-off-by: Jonas Gorski <jonas.gorski@gmail.com>

* include/kernel: add custom USER/DOMAIN config optionsFelix Fietkau2016-01-281-0/+2
| | | | | | | | | | | | | | | These allow the generated kernel's build metadata to be defined explicitly. This metadata is reported, eg, at boot time and in `uname -a` on running systems. If the variables aren't configured, the current build system username and hostname are used as normal. The motivation for this option is to achive reproducible (bit-for-bit identical) kernel builds of official openwrt releases.

* build: Allow kernel modules to set build ID debug symbolFelix Fietkau2015-10-301-1/+2
| | | | | | | | | | | | | | | | | | | | This change adds support for specifying a build ID for kernel modules. This is done by setting PKG_BUILD_ID to a hexadecimal string, which will then be passed to the kernel linker. In addition, when this flag is set, the build ID debug symbol (.note.gnu.build-id) will not be stripped from the kernel module. This symbol is exported in sysfs by the kernel (if the kernel is compiled with CONFIG_KALLSYMS) and so can be used to uniquely identify a version of a kernel module in a running kernel. This is useful for keeping track of different versions of a module when doing experiments and development. Modules that specify the build ID will be ~100 bytes larger (depending on the length of the build ID specified). There is no size difference for kernel modules that do not set this variable.

* build: make sure modules are modposted after initramfs image is builtFelix Fietkau2014-10-051-2/+2
| | | | | | | | | | | | | | Otherwise the modpost steps for individual modules that are compiled manually (using make package/<name_of_module>/install) will give warning of missing symbols when that module depends other modules. This is caused by the Module.symvers file not containing any symbols anymore of external modules when the initramfs image is built without specifically giving the modules target.

* include: Clean-up kernel git command options managementJohn Crispin2014-06-021-1/+7
| | | | | | | | | | | | | | | | | The way git options are managed in kernel-defaults.mk makes additions difficult. If requires different code path for each option; it's ok so far as we handle only one option, but if we want to make the git clone mechanism more flexible, more option will be required, which will become tedious. So; we'll move the GIT options into a variable, that may or may not be set depending on the configuration, and we'll pass this variable to the git command.

* config: Remove KERNEL_GIT_LOCAL_REPOSITORY optionJohn Crispin2014-06-021-8/+2
| | | | | | | | | | | | | | | | | | | | The GIT_LOCAL_REPOSITORY option adds the --reference argument to the git clone kernel command line, if KERNEL_GIT_CLONE_URI is set. This option is intended to speed-up the repo creation by using local objets rather than downloading it. However, a local repo can be cloned much faster by setting GIT_LOCAL_REPOSITORY directly to the local tree. In that case, git clone will bypass the normal "git aware" transport mechanism and clone the repository by copying and hardlinking objects rather than downloading it, resulting in a significant speed increase. That makes the GIT_LOCAL_REPOSITORY option pretty useless so we'll just remove it and recommand the usage of KERNEL_GIT_CLONE_URI directly.
