Subject: [dpdk-stable] missing ring memory barrier in 17.11
Date: Tue, 01 Oct 2019 09:41:59 +0200 [thread overview]
Message-ID: <2613008.bAPQ5MWe9V@xps> (raw)
Hi Luca, Gavin,
It seems the fix 85cffb2eccd9 ("ring: enforce reading tail before slots")
should be backported in 17.11.
This patch is missing because the root cause is wrongly identified.
It is referenced as
Fixes: c9fb3c62896f ("ring: move code in a new header file")
in 18.02, but in reality it is from 17.05:
Fixes: 0dfc98c507b1 ("ring: separate out head index manipulation")
Do you agree?
