Puranjay Mohan 535fb2160a bpf: hardcode BPF_PROG_PACK_SIZE to 2MB * num_possible_nodes() ... [ Upstream commit d6170e4aaf86424c24ce06e355b4573daa891b17 ] On some architectures like ARM64, PMD_SIZE can be really large in some configurations. Like with CONFIG_ARM64_64K_PAGES=y the PMD_SIZE is 512MB. Use 2MB * num_possible_nodes() as the size for allocations done through the prog pack allocator. On most architectures, PMD_SIZE will be equal to 2MB in case of 4KB pages and will be greater than 2MB for bigger page sizes. Fixes: ea2babac63 ("bpf: Simplify bpf_prog_pack_[size|mask]") Reported-by: "kernelci.org bot" <bot@kernelci.org> Closes: https://lore.kernel.org/all/7e216c88-77ee-47b8-becc-a0f780868d3c@sirena.org.uk/ Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202403092219.dhgcuz2G-lkp@intel.com/ Suggested-by: Song Liu <song@kernel.org> Signed-off-by: Puranjay Mohan <puranjay12@gmail.com> Message-ID: <20240311122722.86232-1-puranjay12@gmail.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: Sasha Levin <sashal@kernel.org>		2024-03-26 18:19:41 -04:00
