Subject: [PATCH AUTOSEL 5.6 14/47] net sched: fix reporting the first-time use timestamp
Date: Thu, 28 May 2020 07:55:27 -0400	[thread overview]
Message-ID: <20200528115600.1405808-14-sashal@kernel.org> (raw)
In-Reply-To: <20200528115600.1405808-1-sashal@kernel.org>

From: Roman Mashak <mrv@mojatatu.com>

[ Upstream commit b15e62631c5f19fea9895f7632dae9c1b27fe0cd ]

When a new action is installed, firstuse field of 'tcf_t' is explicitly set
to 0. Value of zero means "new action, not yet used"; as a packet hits the
action, 'firstuse' is stamped with the current jiffies value.

tcf_tm_dump() should return 0 for firstuse if action has not yet been hit.

Fixes: 48d8ee1694dd ("net sched actions: aggregate dumping of actions timeinfo")
