My pattern: @exists@ identifier rta, param, key, keylen; position p; @@ otx_cpt_aead_cbc_aes_sha_setkey(..., unsigned char *key, unsigned int keylen) { ... * if (RTA_PAYLOAD(rta) < sizeof(*param))@p goto badkey; ... * key += RTA_ALIGN(rta->rta_len); * keylen -= RTA_ALIGN(rta->rta_len); ... } $ spatch --no-includes --include-headers --cocci-file test.cocci drivers/crypto/marvell/octeontx/otx_cptvf_algs.c init_defs_builtins: /usr/lib64/coccinelle/standard.h minus: parse error: File "test.cocci", line 13, column 9, charpos = 219 around = 'RTA_ALIGN', whole content = * key += RTA_ALIGN(rta->rta_len); What can I do to match RTA_ALIGN(...) lines?
