Subject: [PATCH AUTOSEL 4.14 11/95] nl80211: Add NL80211_FLAG_CLEAR_SKB flag for other NL commands
Date: Tue, 7 May 2019 01:37:00 -0400 [thread overview]
Message-ID: <20190507053826.31622-11-sashal@kernel.org> (raw)
In-Reply-To: <20190507053826.31622-1-sashal@kernel.org>
From: Sunil Dutt <usdutt@codeaurora.org>
[ Upstream commit d6db02a88a4aaa1cd7105137c67ddec7f3bdbc05 ]
This commit adds NL80211_FLAG_CLEAR_SKB flag to other NL commands
that carry key data to ensure they do not stick around on heap
after the SKB is freed.
Also introduced this flag for NL80211_CMD_VENDOR as there are sub
commands which configure the keys.
