Subject: [Cocci] Regression since recent parentypes patches were merged
Date: Tue, 12 May 2020 13:57:25 +0200 [thread overview]
Message-ID: <fa30c7d6-5278-9575-517b-31658b1a37c3@linbit.com> (raw)
Hi Jaskaran,
Hi all,
I have noticed a regression in spatch since the recent SmPL improvements
were merged. Here is a small reproducer:
@@
struct socket *sock;
struct sockaddr *uaddr;
int peer;
@@
{
+int ___addr_len;
...
- sock->ops->getname(sock, uaddr, peer);
+ sock->ops->getname(sock, uaddr, &___addr_len, peer);
...
}
This used to parse just fine, however now it errors out:
$ spatch --parse-cocci compat.cocci
init_defs_builtins: /usr/local/bin/../lib/coccinelle/standard.h
minus: parse error:
File "compat.cocci", line 9, column 13, charpos = 98
around = 'getname',
whole content = - sock->ops->getname(sock, uaddr, peer);
I have bisected the problem and it appears that the first bad commit is:
commit c280375635f62dfbe052709e4e47a82140d32ce5

Add parentypes to SmPL
This allows the SmPL and C ASTs to better match up, which enables
more transformations. The patch is very large, so I have left
the different messages as they were proposed in the original
patch series.
Which is unfortunately huge, and since it was squashed together I really
can't be any more specific.
Anyways, is this a bug? Or was I doing something wrong in the first place?
Thanks and best regards,
