* bpftools: update to v5.11.16, simplify makeTony Ambardar2021-04-241-11/+0
| | | | | | | | | | | | | | | | 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 param order for install on macOSGeorgi Valkov2021-03-071-0/+11
| | | | | | | Fix: bpftools 5.11.2 does not compile on macOS, because the -m option was placed between src and dst. Corrected by moving -m 644 before src. Signed-off-by: Georgi Valkov <gvalkov@abv.bg>
* bpftools: update to latest stable 5.11.2Tony Ambardar2021-03-011-5/+0
| | | | | | | Compile and run-tested on malta/mip32be, using bpftool directly and also libbpf (linked with tc) to inspect and load simple eBPF programs. Signed-off-by: Tony Ambardar <itugrok@yahoo.com>
* bpftools: update to 5.10.10Tony Ambardar2021-01-254-324/+0
| | | | | | | | | | | | | 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 Ambardar2020-09-185-28/+62
| | | | | | | | | | | | | | | | | 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 Ambardar2020-08-314-0/+346
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>
