Subject: [IPV4] nl_fib_lookup: Initialise res.r before fib_res_put(&res)
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=912a41a4ab935ce8c4308428ec13fc7f8b1f18f4;p=openwrt%2Fstaging%2Fblogic.git

[IPV4] nl_fib_lookup: Initialise res.r before fib_res_put(&res)

When CONFIG_IP_MULTIPLE_TABLES is enabled, the code in nl_fib_lookup()
needs to initialize the res.r field before fib_res_put(&res) - unlike
fib_lookup(), a direct call to ->tb_lookup does not set this field.
