Test refcounted local kptr functionality added in previous patches in the series. Usecases which pass verification: * Add refcounted local kptr to both tree and list. Then, read and - possibly, depending on test variant - delete from tree, then list. * Also test doing read-and-maybe-delete in opposite order * Stash a refcounted local kptr in a map_value, then add it to a rbtree. Read from both, possibly deleting after tree read. * Add refcounted local kptr to both tree and list. Then, try reading and deleting twice from one of the collections. * bpf_refcount_acquire of just-added non-owning ref should work, as should bpf_refcount_acquire of owning ref just out of bpf_obj_new Usecases which fail verification: * The simple successful bpf_refcount_acquire cases from above should both fail to verify if the newly-acquired owning ref is not dropped Signed-off-by: Dave Marchevsky <davemarchevsky@fb.com> Link: https://lore.kernel.org/r/20230415201811.343116-10-davemarchevsky@fb.com Signed-off-by: Alexei Starovoitov <ast@kernel.org>
