Add a test to verifier_linked_scalars that exercises the base_id consistency check for BPF_ADD_CONST linked scalars during state pruning. With the fix, pruning fails and the verifier discovers the true branch's R3 is too wide for the stack access. # LDLIBS=-static PKG_CONFIG='pkg-config --static' ./vmtest.sh -- ./test_progs -t verifier_linked_scalars [...] #613/22 verifier_linked_scalars/scalars_stale_delta_from_cleared_id:OK #613/23 verifier_linked_scalars/scalars_stale_delta_from_cleared_id_alu32:OK #613/24 verifier_linked_scalars/linked scalars: add_const base_id must be consistent for pruning:OK #613 verifier_linked_scalars:OK Summary: 1/24 PASSED, 0 SKIPPED, 0 FAILED Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Link: https://lore.kernel.org/r/20260410232651.559778-2-daniel@iogearbox.net Signed-off-by: Alexei Starovoitov <ast@kernel.org>
