Hi,
I noticed some noise in my server log, so I thought it might be time to
finish this deprecation. One concern I have is about xt_connbytes. The
Kconfig for NETFILTER_XT_MATCH_CONNBYTES used to 'SELECT NF_CT_ACCT'
which forced nf_conntrack.acct=1. As long as the value of NF_CT_ACCT_DEFAULT
remains 1, then xt_connbytes should be OK.
Yeah, but we need to take care of the other case anyways. As I've
repeatedly stated, connbytes needs to enable accounting when the
first rule using it is added.
You also don't need to update the defconfigs, architecture maintainers
can take care of that.

Subject: [PATCH] netfilter: Complete the deprecation of CONFIG_NF_CT_ACCT
CONFIG_NF_CT_ACCT has been deprecated for awhile and
was originally scheduled for removal by 2.6.29.
Removing support for this config option also stops
this deprecation warning message in the kernel log.
[ 61.669627] nf_conntrack version 0.5.0 (16384 buckets, 65536 max)
[ 61.669850] CONFIG_NF_CT_ACCT is deprecated and will be removed soon. Please use
[ 61.669852] nf_conntrack.acct=1 kernel parameter, acct=1 nf_conntrack module option or
[ 61.669853] sysctl net.netfilter.nf_conntrack_acct=1 to enable it.

This option adds a `connbytes' match, which allows you to match the
number of bytes and/or packets for each direction within a connection.
