* bpftools: fix library path on 64 bit systemsFelix Fietkau2022-03-191-3/+3
| | | | | | | drop the use of LIB_SUFFIX Fixes: 00cbf6f6ab1d ("bpftools: update to standalone bpftools + libbpf, use the latest version") Signed-off-by: Felix Fietkau <nbd@nbd.name>

* bpftools: update to v5.11.16, simplify makeTony Ambardar2021-04-241-5/+7
| | | | | | | | | | | | | | | | Update to the latest stable upstream version. Drop unneeded make variables to remove redundant assignments seen during invocation of package Makefile. Also remove the following patch now included upstream: * 200-fix-install-param-order-on-macos.patch Compile and run-tested on malta/mips32be, using bpftool directly and also libbpf (linked with tc) to inspect and load simple eBPF programs.

* bpftools: fix feature override for masking clangTony Ambardar2021-04-241-1/+1
| | | | | | | | | Rename feature variable clang-bpf-global-var following upstream changes. This restores the HAVE_CLANG feature override and should avoid rare build errors where a recent host clang and BTF-enabled host kernel are present. Fixes: 23be333401f0 ("bpftools: update to 5.10.10") Signed-off-by: Tony Ambardar <itugrok@yahoo.com>
* bpftools: drop unneeded libintl linking for NLSTony Ambardar2021-04-031-5/+1
| | | | | | | | There is no direct linking of libintl from bpftools, only secondary linking through libelf, so remove "-lintl" from TARGET_LDFLAGS. Fixes: 5582fbd6135f ("bpftools: support NLS, fix ppc build and update to 5.8.9") Signed-off-by: Tony Ambardar <itugrok@yahoo.com>
* bpftools: fix libbpf pkgconfig fileTony Ambardar2021-03-071-0/+4
| | | | | | | | | | | | | | | | | | | | | The pkgconfig file hardcodes a host library directory which cannot be overridden by OpenWrt during builds. Use SED to fix this and potential include directory problems, as is done with several other packages. This fixes a strange issue intermittently seen building iproute2 on the oxnas target: iptables modules directory: /usr/lib/iptables libc has setns: yes SELinux support: no libbpf support: no libbpf version 0.3.0 is too low, please update it to at least 0.1.0 LIBBPF_FORCE=on set, but couldn't find a usable libbpf Fixes: 2f0d672088c3 ("bpftools: add utility and library packages supporting eBPF usage") Reported-by: Russell Senior <russell@personaltelco.net> Signed-off-by: Tony Ambardar <itugrok@yahoo.com>

* build: reorder more BuildPackages lines to deal with ABI_VERSIONFelix Fietkau2021-02-161-1/+1
| | | | | | | After the ABI version rework, packages need to be declared in the order of their dependencies, so that dependent packages will use the right ABI version Signed-off-by: Felix Fietkau <nbd@nbd.name>
* bpftools: update to 5.10.10Tony Ambardar2021-01-251-2/+2
| | | | | | | | | | | | | Use the latest stable kernel since the previous 5.8.x series is EOL. Also drop the following patches recently accepted upstream: * 001-libbpf-ensure-no-local-symbols-counted-in-ABI-check.patch * 002-libbpf-fix-build-failure-from-uninitialized-variable.patch * 003-bpftool-allow-passing-BPFTOOL_VERSION-to-make.patch * 004-v5.9-bpftool-use-only-ftw-for-file-tree-parsing.patch Signed-off-by: Tony Ambardar <itugrok@yahoo.com>
* bpftools: support NLS, fix ppc build and update to 5.8.9Tony Ambardar2020-09-181-5/+10
| | | | | | | | | | | | | | | | | With global NLS support enabled (CONFIG_BUILD_NLS), the linked libelf.so and libbfd.so libraries will depend on libintl.so. Import the nls.mk helper to set library prefixes and flags accordingly, and also conditionally add "-lintl" as link-time library. Fix a build error on ppc due to a EDEADLOCK redefinition in errno.h. Use upstream stable kernel 5.8.9, and fix overriding of feature detection to only allow/hide detected features. Also refresh existing patches.

* bpftools: add utility and library packages supporting eBPF usageTony Ambardar2020-08-311-0/+162
Add support for building bpftool and libbpf from the latest 5.8.3 kernel sources, ensuring up-to-date functionality and fixes. Both are written to be backwards compatible, which simplfies build and usage across different OpenWRT image kernels. 'bpftool' is the primary userspace tool widely used for introspection and manipulation of eBPF programs and maps. Two variants are built: a 'full' version which supports object disassembly and depends on libbfd/libopcodes (total ~500KB); and a 'minimal' version without disassembly functions and dependencies. The default 'minimal' variant is otherwise fully functional, and both are compiled using LTO for further (~30KB) size reductions. 'libbpf' provides shared/static libraries and dev files needed for building userspace programs that perform eBPF interaction. Several cross-compilation and build-failure problems are addressed by new patches and ones backported from farther upstream: * 001-libbpf-ensure-no-local-symbols-counted-in-ABI-check.patch * 002-libbpf-fix-build-failure-from-uninitialized-variable.patch * 003-bpftool-allow-passing-BPFTOOL_VERSION-to-make.patch * 004-v5.9-bpftool-use-only-ftw-for-file-tree-parsing.patch Signed-off-by: Tony Ambardar <itugrok@yahoo.com>
