Subject: [PATCH 4.14 64/74] selftests: rtnetlink: add addresses with fixed life time
Date: Tue, 7 Jan 2020 21:55:29 +0100 [thread overview]
Message-ID: <20200107205227.111178135@linuxfoundation.org> (raw)
In-Reply-To: <20200107205135.369001641@linuxfoundation.org>
From: Florian Westphal <fw@strlen.de>
[ Upstream commit 3cfa148826e3c666da1cc2a43fbe8689e2650636 ]
This exercises kernel code path that deal with addresses that have
a limited lifetime.
Without previous fix, this triggers following crash on net-next:
BUG: KASAN: null-ptr-deref in check_lifetime+0x403/0x670
Read of size 8 at addr 0000000000000010 by task kworker [..]
