[X25]: Add missing x25_neigh_put
The function x25_get_neigh increments a reference count. At the point of the second goto out, the result of calling x25_get_neigh is only stored in a local variable, and thus no one outside the function will be able to decrease the reference count. Thus, x25_neigh_put should be called before the return in this case. The problem was found using the following semantic match. (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ type T,T1,T2; identifier E; statement S; expression x1,x2,x3; int ret; @@ T E; ... * if ((E = x25_get_neigh(...)) == NULL) S ... when != x25_neigh_put(...,(T1)E,...) when != if (E != NULL) { ... x25_neigh_put(...,(T1)E,...); ...} when != x1 = (T1)E when != E = x3; when any if (...) { ... when != x25_neigh_put(...,(T2)E,...) when != if (E != NULL) { ... x25_neigh_put(...,(T2)E,...); ...} when != x2 = (T2)E ( * return; | * return ret; ) } // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S.
