Hello Luiz Augusto von Dentz,
This is a semi-automatic email about new static checker warnings.
The patch 8aca46f91c42: "Bluetooth: mgmt: Introduce mgmt_alloc_skb
and mgmt_send_event_skb" from Dec 3, 2021, leads to the following
Smatch complaint:
net/bluetooth/mgmt_util.c:82 mgmt_send_event_skb()
warn: variable dereferenced before check 'skb' (see line 80)
net/bluetooth/mgmt_util.c
79 struct mgmt_hdr *hdr;
80 int len = skb->len;
^^^^^^^^^
Dereference
81
82 if (!skb)
^^^^
Too late
83 return -EINVAL;
84
regards,
dan carpenter
