From: GuoJia Liao <liaoguojia@huawei.com> driver inclusion category: bugfix bugzilla: NA CVE: NA ---------------------------- Parameter 'vf_id' used for receiving the vf id from external input. It's assigned as 'int'. However, when using kstrtouint(), there is a mismatch type between 'int' to 'unsigned int', causing a risk of negetive numbers to an unsigned int. definition of kstrtouint() as below: int kstrtouint ( const char * s, unsigned int base, unsigned int * res); Fixes: f3b9739ecaad ("net: hns3: add dumping vlan filter config in debugfs") Signed-off-by: GuoJia Liao <liaoguojia@huawei.com> Reviewed-by: Peng Li <lipeng321@huawei.com> Reviewed-by: Weiwei Deng <dengweiwei@huawei.com> Reviewed-by: Zhaohui Zhong <zhongzhaohui@huawei.com> Reviewed-by: Junxin Chen <chenjunxin1@huawei.com> Signed-off-by: Shengzui You <youshengzui@huawei.com> Signed-off-by: Yang Yingliang <yangyingliang@huawei.com> --- drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_debugfs.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_debugfs.c b/drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_debugfs.c index 5190212922a0..fd5cfb1e6311 100644 --- a/drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_debugfs.c +++ b/drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_debugfs.c @@ -1622,7 +1622,7 @@ static void hclge_dbg_dump_vlan_filter(struct hclge_dev *hdev, struct hclge_vport *vport; struct hclge_desc desc; bool has_vlan_used; - int vf_id; + u32 vf_id; int ret; ret = kstrtouint(cmd_buf, 0, &vf_id); -- 2.25.1
