Subject: [PATCH bpf-next 6/7] selftests: bpf: Extend sk_assign for address proxy
Date: Thu, 12 Mar 2020 16:36:47 -0700 [thread overview]
Message-ID: <20200312233648.1767-7-joe@wand.net.nz> (raw)
In-Reply-To: <20200312233648.1767-1-joe@wand.net.nz>
Extend the socket assign test program to also validate that connections
to foreign addresses may also be proxied to a user agent via this
mechanism.
Signed-off-by: Joe Stringer <joe@wand.net.nz>
