[Cocci] How to match function-like macro calls, e.g. RTA_ALIGN(rta->rta_len)?

[Denis Efremov]

Hi,

Let's suppose I want to match otx_cpt_aead_cbc_aes_sha_setkey() function from
drivers/crypto/marvell/octeontx/otx_cptvf_algs.c file (linux kernel).

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?

Thanks,
Denis
