bpf-headers: add a package with kernel headers for ebpf In order to genererate suitable kernel headers, a 5.10 kernel tree is prepared with a default config for mips. The arch is forced to mips in order to avoid issues with inline asm on various architectures in a way that doesn't involve relying on the host toolchain/headers. It also has the advantage of supporting both endian types Signed-off-by: Felix Fietkau <nbd@nbd.name>

kernel: bpf-headers: fix build error when testing kernel is used Now that we have separate files for each kernel version, only the version/hash for the target kernel are available. This cause a missing hash error (and wrong kernel version) for bpf-headers when a testing kernel version is used for the current target. Fix this error by manually including the kernel version/hash file for the specific kernel version requested. Signed-off-by: Ansuel Smith <ansuelsmth@gmail.com>

bpf-headers: Fix download URL with kernel 6.1 This fixes the download of the kernel 5.15 for the bpf-headers when kernel 6.1 is build for the target. Even if kernel 6.1 was selected for the target we still use kernel 5.15 for the bpf-headers. The download script tried to download the 5.15 kernel from the 6.x directory on kernel,org and this failed. Define PKG_SOURCE_URL based on PKG_PATCHVER and not KERNEL_BASE like done in kernel.mk. Without this change it tries to download the kernel from this URL: ttps://cdn.kernel.org/pub/linux/kernel/v6.x/linux-5.15.129.tar.xz Fixes: #13190 Fixes: #13671 Fixes: #13814 Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
