Subject: [DCCP] ipv6: dccp_v6_send_response() has a DST leak too.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0cbd782507c502428c8ab3e91bee3940c19ac4d4;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[DCCP] ipv6: dccp_v6_send_response() has a DST leak too.

It was copy&pasted from tcp_v6_send_synack() which has
a DST leak recently fixed by Eric W. Biederman.

So dccp_v6_send_response() needs the same fix too.
