Julia Lawall 841f1d92fb net/rfkill/rfkill-gpio.c: introduce missing kfree ... Error handling code following a kmalloc should free the allocated data. The label fail_alloc already does this for rfkill. A simplified version of the semantic match that finds the problem is as follows: (http://coccinelle.lip6.fr) // <smpl> @r exists@ local idexpression x; statement S; identifier f1; position p1,p2; expression *ptr != NULL; @@ x@p1 = \(kmalloc\|kzalloc\|kcalloc\)(...); ... if (x == NULL) S <... when != x when != if (...) { <+...x...+> } x->f1 ...> ( return \(0\|<+...x...+>\|ptr\); | return@p2 ...; ) @script:python@ p1 << r.p1; p2 << r.p2; @@ print "* file: %s kmalloc %s return %s" % (p1[0].file,p1[0].line,p2[0].line) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: John W.
