tools/dwarves: add host package 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.

tools/dwarves: update to v1.27 Update to the latest upstream version and add a patch that enables pahole reproducible builds if SOURCE_DATE_EPOCH is defined in the environment. This patch helps avoid BTF-related module loading problems with packages built separately from the kernel such as mac80211 or kselftests-bpf, e.g.: [ 16.858856] BPF: type_id=1185 bits_offset=0 [ 16.859099] BPF: [ 16.859199] BPF: Invalid name [ 16.859352] BPF: [ 16.859612] failed to validate module [cfg80211] BTF: -22 [ 17.015178] PPP generic driver version 2.4.2 [ 17.052703] NET: Registered PF_PPPOX protocol family [ 17.348722] BPF: type_id=1185 bits_offset=0 [ 17.348912] BPF: [ 17.348996] BPF: Invalid name [ 17.349106] BPF: [ 17.349220] failed to validate module [cfg80211] BTF: -22 [ 17.472070] kmodloader: 3 modules could not be probed [ 17.473133] kmodloader: - cfg80211 - 0 [ 17.473762] kmodloader: dependency not loaded cfg80211 [ 17.474421] kmodloader: - mac80211 - 1 [ 17.474988] kmodloader: dependency not loaded mac80211 [ 17.475632] kmodloader: dependency not loaded cfg80211 [ 17.476263] kmodloader: - mac80211_hwsim - 2 root@OpenWrt:/usr/libexec/kselftests-bpf# insmod bpf_testmod.ko [ 4735.776792] missing module BTF, cannot register kfuncs [ 4735.777371] missing module BTF, cannot register kfuncs [ 4735.777955] missing module BTF, cannot register kfuncs [ 4735.778452] missing module BTF, cannot register kfuncs Release Notes: https://lore.kernel.org/bpf/ZmjBHWw-Q5hKBiwA@x1/ Signed-off-by: Tony Ambardar <itugrok@yahoo.com> Link: https://github.com/openwrt/openwrt/pull/15697 Signed-off-by: Christian Marangi <ansuelsmth@gmail.com>

tools: prefer gz or bz2 tarballs In the light of recent XZ events, and fundamental XZ issues lets work on moving away from using XZ. So, use gz compressed tarballs as sources whenever possible. dwarves only offers bz2 compressed tarballs, so use those as size difference is minor compared to XZ.
