From: Julia Lawall <julia@xxxxxxx> At this point, the new_param that has just been allocated has not been stored in the list, so it and new_param->name, once it is defined, have to be freed separately. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @exists@ local idexpression x; statement S,S1; expression E; identifier fl; expression *ptr != NULL; @@ x = \(kmalloc\|kzalloc\|kcalloc\)(...); ... if (x == NULL) S <... when != x when != if (...) { <+...kfree(x)...+> } when any when != true x == NULL x->fl ...> ( if (x == NULL) S1 | if (...) { ... when != x when forall ( return \(0\|<+...x...+>\|ptr\); | * return ...; ) } ) // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> --- drivers/target/iscsi/iscsi_target_parameters.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/drivers/target/iscsi/iscsi_target_parameters.c b/drivers/target/iscsi/iscsi_target_parameters.c index 252e246..b8dbe44 100644 --- a/drivers/target/iscsi/iscsi_target_parameters.c +++ b/drivers/target/iscsi/iscsi_target_parameters.c @@ -584,6 +584,7 @@ int iscsi_copy_param_list( if (!new_param->name) { pr_err("Unable to allocate memory for" " parameter name.\n"); + kfree(new_param); goto err_out; } @@ -592,6 +593,8 @@ int iscsi_copy_param_list( if (!new_param->value) { pr_err("Unable to allocate memory for" " parameter value.\n"); + kfree(new_param->name); + kfree(new_param); goto err_out; } -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
