Subject: [PATCH ipsec-next] xfrm: fix 'passing zero to ERR_PTR()' warning
Date: Wed, 25 Jul 2018 16:54:33 +0800 [thread overview]
Message-ID: <20180725085433.18756-1-yuehaibing@huawei.com> (raw)
Fix a static code checker warning:
net/xfrm/xfrm_policy.c:1836 xfrm_resolve_and_create_bundle() warn: passing zero to 'ERR_PTR'
xfrm_tmpl_resolve return 0 just means no xdst found, return NULL
instead of passing zero to ERR_PTR.
Fixes: d809ec895505 ("xfrm: do not assume that template resolving always returns xfrms")
