Subject: [PATCH nf] netfilter: conntrack: make sysctls per-namespace again
Date: Tue, 27 Aug 2019 13:24:52 +0200	[thread overview]
Message-ID: <20190827112452.31479-1-fw@strlen.de> (raw)
In-Reply-To: <20190827135754.7d460ef8@pixies>

When I merged the extension sysctl tables with the main one I forgot to
reset them on netns creation.  They currently read/write init_net settings.

Fixes: d912dec12428 ("netfilter: conntrack: merge acct and helper sysctl table with main one")
Fixes: cb2833ed0044 ("netfilter: conntrack: merge ecache and timestamp sysctl tables with main one")
Reported-by: Shmulik Ladkani <shmulik.ladkani@gmail.com>
Signed-off-by: Florian Westphal <fw@strlen.de>

 Shmulik, could you please check if this fixes the bug for you?
 Thanks!
