Hello Pravin B Shelar,
This is a semi-automatic email about new static checker warnings.
The patch fc4099f17240: "openvswitch: Fix egress tunnel info." from
Oct 22, 2015, leads to the following Smatch complaint:
include/net/dst_metadata.h:69 tun_dst_unclone()
warn: variable dereferenced before check 'md_dst' (see line 66)
include/net/dst_metadata.h
65 struct metadata_dst *md_dst = skb_metadata_dst(skb);
66 int md_size = md_dst->u.tun_info.options_len;
^^^^^^^^
New dereference.
67 struct metadata_dst *new_md;
68
69 if (!md_dst)
^^^^^^^
New NULL check.
70 return ERR_PTR(-EINVAL);
71
regards,
dan carpenter
