Rename the calls to arena_malloc andarena_free instead to prevent collisions.Reported-by: Ihor Solodrai <ihor.solodrai@linux.dev>Signed-off-by: Emil Tsalapatis <etsal@meta.com>Fixes: 86426a28c52d ("selftests/bpf: Add buddy allocator for libarena")Acked-by: Ihor Solodrai <ihor.solodrai@linux.dev>Link: https://lore.kernel.org/r/20260428134252.2783519-1-etsal@meta.comSigned-off-by: Alexei Starovoitov <ast@kernel.org> List of files: /linux/tools/testing/selftests/bpf/libarena/Makefile Tue, 28 Apr 2026 15:42:52 +0200 Emil Tsalapatis <emil@etsalapatis.com> 86426a28c52d756a5edbe29885716128b8915991 - selftests/bpf: Add buddy allocator for libarena http://kernelsources.org:8080/source/history/linux/tools/testing/selftests/bpf/libarena/Makefile#86426a28c52d756a5edbe29885716128b8915991 selftests/bpf: Add buddy allocator for libarenaAdd a byte-oriented buddy allocator for libarena. The buddyallocator provides an alloc/free interface for small arena allocationsranging from 16 bytes to 512 KiB. Lower allocations values are roundedup to 16 bytes. The buddy allocator does not handle larger allocationsthat can instead use the existing bpf_arena_{alloc, free}_pages() kfunc.Signed-off-by: Emil Tsalapatis <emil@etsalapatis.com>Link: https://lore.kernel.org/r/20260426190338.4615-7-emil@etsalapatis.comSigned-off-by: Alexei Starovoitov <ast@kernel.org> List of files: /linux/tools/testing/selftests/bpf/libarena/Makefile Sun, 26 Apr 2026 21:03:36 +0200 Emil Tsalapatis <emil@etsalapatis.com> cfc00618b9dfc75cd507f1a4f0d83b4429627399 - selftests/bpf: Add ASAN support for libarena selftests http://kernelsources.org:8080/source/history/linux/tools/testing/selftests/bpf/libarena/Makefile#cfc00618b9dfc75cd507f1a4f0d83b4429627399 selftests/bpf: Add ASAN support for libarena selftestsExpand the arena library selftest infrastructure to supportaddress sanitization.

Modulescan be added just by including the source file in the library's src/subdirectory. Future commits will introduce the library code itself.The code includes workarounds that are removed in subsequent patchesthat ensure bisectability.Signed-off-by: Emil Tsalapatis <emil@etsalapatis.com>Link: https://lore.kernel.org/r/20260426190338.4615-3-emil@etsalapatis.comSigned-off-by: Alexei Starovoitov <ast@kernel.org> List of files: /linux/tools/testing/selftests/bpf/libarena/Makefile Sun, 26 Apr 2026 21:03:32 +0200 Emil Tsalapatis <emil@etsalapatis.com>
