Subject: Re: [Cocci] [PATCH v2] coccinelle: api: add kzfree script
Date: Fri, 5 Jun 2020 00:25:31 +0300	[thread overview]
Message-ID: <378e709b-695a-be84-f4b3-f25dfcdc6ec7@linux.com> (raw)
In-Reply-To: <alpine.DEB.2.21.2006042254240.2577@hadrien>

It looks like a good idea to add type cast, like:

+// Ignore kzfree definition
+// Ignore kasan test
+@r depends on !patch && !(file in "lib/test_kasan.c") && !(file in "mm/slab_common.c") forall@
+expression *E;
+position p;
+type T;
+@@
+
+* \(memset\|memset_explicit\)((T)E, 0, ...);
+  ... when != E
+      when strict
+* \(kfree\|vfree\|kvfree\)(E)@p;
+

and to exclude file "mm/util.c" because it will contain the definition of 
kvfree_sensitive().

I will wait for your recommendation about commented lines and will send v3 after.

Thanks,
Denis
