[PATCH v2 07/11] layerscape/armv8_64b: enable DEBUG_INFO_REDUCED
We currently enable DEBUG_INFO_REDUCED for all targets via the generic kernel config. There is only one subtarget, layerscape/armv8_64b, that overrides this setting. As there is no explanation for this in the commit message that introduced this, and question to its author went unanswered, let's simply drop this symbol from the subtarget config. This way, we have consistency across the tree, and we do not have to introduce a special case when moving this symbol to an OpenWrt kernel config option.

[PATCH v2 09/11] build: add option KERNEL_DEBUG_INFO_BTF
From: Tony Ambardar Generate BTF (BPF Type Format) information from DWARF debug info. This is embedded in the kernel and exported via sysfs as /sys/kernel/btf/vmlinux. BTF data enhances kernel portability and introspection for BPF programs. Selecting this also enables the dwarves host package which provides the pahole tool used for BTF encoding. Test using: "bpftool btf dump file /sys/kernel/btf/vmlinux format c" This needs to depend on KERNEL_DEBUG_INFO_REDUCED not being set, otherwise we can enable both KERNEL_DEBUG_INFO_BTF and KERNEL_DEBUG_INFO_REDUCED, which will result in undefined behaviour.

[PATCH v2 05/11] tools/dwarves: add host package
From: Tony Ambardar
dwarves is a set of tools that use the debugging information inserted in
ELF binaries by compilers such as GCC. Utilities in the dwarves suite
include pahole, which can be used to find alignment holes in structs and
classes, and also extracts other information such as CPU cacheline
alignment, helping pack those structures to achieve more cache hits.
These tools are also used to encode and read the BTF type information
format used with the bpf syscall, making this a Linux build dependency
when using kernel BTF information.

[PATCH v2 01/11] elfutils: move host build to tools
The upcoming dwarves host package requires elfutils. As dependencies for tools must exist in tools, we need to move elfutils host build there. As there is at least one package that depends on this, and there is no proper way to create such dependency in the build system, build it unconditionally when not building on macOS.

[PATCH v2 00/11] BPF events and Type Format support
This series adds support for BPF events, and BPF Type Format [1]. It supersedes [2]. BPF events can be used to send data to userspace for post-processing or logging. Building the kernel with BTF support is required to run BPF CO-RE applications. Some fixes are required to make this possible, and it will not be possible to enable BTF when building on macOS, due to incompatibilities. Also see Github pull requests [3] and [4].

Hi, is the 22.03.0-rc1 going be tagged and built soon? It is now almost two weeks since the 22.03 branching, and also the 22.03 buildbot has been hapily crunching build for over a week by now. All targets are steadily green (with the exception of at91/sama7 and its packages arm_cortex-a7_vfpv4 ). To get more real-life feedback (e.g. regarding firewall4), we should get the rc1 out soon, so that there would be an official stable build for the general populace. (Based on the recent commit activity, the developer interest is quickly moving toward kernel 5.15 etc. new stuff, so likely not much 22.03-specific polishing is happening. Same story as with earlier releases.) Hi Hannu, Thanks for bringing this topic up. From my side there is nothing blocking tagging and building OpenWrt 22.03.0-rc1 and I think we should do it soon. Are there any objectsions from anyone to tag in the next days? Who wants to take care of it?

netifd patch 60ghz AD AP mode
Hello, I believe there is a typo in netifd-wireless.sh. My fist patch sent here so I hope it is in good format. When an AD device is placed in AP mode the wrong hWmode is writen to hostapd. This should fix it. For me it does.
