Subject: sysctls below net.ipv[46].conf.all not working as expected
Date: Wed, 29 Dec 2010 17:06:07 +0100	[thread overview]
Message-ID: <20101229160607.GH14221@pengutronix.de> (raw)

Hello,

I did the following:

	cassiopeia:~# sysctl net.ipv6.conf.all.use_tempaddr
	net.ipv6.conf.all.use_tempaddr = 0

	cassiopeia:~# sysctl net.ipv6.conf.eth0.use_tempaddr
	net.ipv6.conf.eth0.use_tempaddr = 0

	cassiopeia:~# sysctl -w net.ipv6.conf.all.use_tempaddr=1
	net.ipv6.conf.all.use_tempaddr = 1

	cassiopeia:~# sysctl net.ipv6.conf.all.use_tempaddr
	net.ipv6.conf.all.use_tempaddr = 1

	cassiopeia:~# sysctl net.ipv6.conf.eth0.use_tempaddr
	net.ipv6.conf.eth0.use_tempaddr = 0

Here I would have expected that eth0's use_tempaddr is 1, too.  The
problem is not that this entry isn't writeable:

	cassiopeia:~# sysctl -w net.ipv6.conf.eth0.use_tempaddr=1
	net.ipv6.conf.eth0.use_tempaddr = 1

	cassiopeia:~# sysctl net.ipv6.conf.eth0.use_tempaddr
	net.ipv6.conf.eth0.use_tempaddr = 1

I got the same results when using net.ipv4.conf.all.rp_filter (and
net.ipv4.conf.eth0.rp_filter resp.)

Is this a bug or just my failure to see how conf/all works?

Best regards
Uwe
