Hi Kuniyuki, kernel test robot noticed the following build warnings: [auto build test WARNING on bpf-next/net] url: https://github.com/intel-lab-lkp/linux/commits/Kuniyuki-Iwashima/tcp-Save-lock_sock-for-memcg-in-inet_csk_accept/20250823-062322 base: https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next.git net patch link: https://lore.kernel.org/r/20250822221846.744252-6-kuniyu%40google.com patch subject: [PATCH v1 bpf-next/net 5/8] bpf: Support bpf_setsockopt() for BPF_CGROUP_INET_SOCK_(CREATE|ACCEPT). config: arm-randconfig-r131-20250824 (https://download.01.org/0day-ci/archive/20250824/202508240731.UPB4k4Uo-lkp@xxxxxxxxx/config) compiler: arm-linux-gnueabi-gcc (GCC) 8.5.0 reproduce: (https://download.01.org/0day-ci/archive/20250824/202508240731.UPB4k4Uo-lkp@xxxxxxxxx/reproduce) If you fix the issue in a separate patch/commit (i.e. not just a new version of the same patch/commit), kindly add following tags | Reported-by: kernel test robot <lkp@xxxxxxxxx> | Closes: https://lore.kernel.org/oe-kbuild-all/202508240731.UPB4k4Uo-lkp@xxxxxxxxx/ sparse warnings: (new ones prefixed by >>) net/core/filter.c:6322:9: sparse: sparse: switch with no cases net/core/filter.c:6363:9: sparse: sparse: switch with no cases net/core/filter.c:1440:39: sparse: sparse: incorrect type in argument 1 (different address spaces) @@ expected struct sock_filter const *filter @@ got struct sock_filter [noderef] __user *filter @@ net/core/filter.c:1440:39: sparse: expected struct sock_filter const *filter net/core/filter.c:1440:39: sparse: got struct sock_filter [noderef] __user *filter net/core/filter.c:1518:39: sparse: sparse: incorrect type in argument 1 (different address spaces) @@ expected struct sock_filter const *filter @@ got struct sock_filter [noderef] __user *filter @@ net/core/filter.c:1518:39: sparse: expected struct sock_filter const *filter net/core/filter.c:1518:39: sparse: got struct sock_filter [noderef] __user *filter >> net/core/filter.c:5752:29: sparse: sparse: symbol 'bpf_sock_setsockopt_proto' was not declared.
