netfilter: log: netns NULL ptr bug when calling from conntrack
Since (69b34fb netfilter: xt_LOG: add net namespace support
for xt_LOG), we hit this:
[ 4224.708977] BUG: unable to handle kernel NULL pointer dereference at 0000000000000388
[ 4224.709074] IP: [<ffffffff8147f699>] ipt_log_packet+0x29/0x270
when callling log functions from conntrack both in and out
are NULL i.e. the net pointer is invalid.
Adding struct net *net in call to nf_logfn() will secure that
there always is a vaild net ptr.

nfnetlink_log: do not expose NFULNL_COPY_DISABLED to user-space
This patch moves NFULNL_COPY_PACKET definition from
linux/netfilter/nfnetlink_log.h to net/netfilter/nfnetlink_log.h
since this copy mode is only for internal use.
I have also changed the value from 0x03 to 0xff. Thus, we avoid
a gap from user-space that may confuse users if we add new
copy modes in the future.
This change was introduced in:
http://www.spinics.net/lists/netfilter-devel/msg13535.html
Since this change is not included in any stable Linux kernel,
I think it's safe to make this change now. Anyway, this copy
mode does not make any sense from user-space, so this patch
should not break any existing setup.

netfilter: nfnetlink_log: fix warning and prototype mismatch
net/netfilter/nfnetlink_log.c:537:1: warning: symbol 'nfulnl_log_packet' was not declared. Should it be static?
Including the proper header also revealed an incorrect prototype.

netfilter: xt_NFLOG: don't call nf_log_packet in NFLOG module.
This patch modifies xt_NFLOG to suppress the call to nf_log_packet()
function. The call of this wrapper in xt_NFLOG was causing NFLOG to
use the first initialized module. Thus, if ipt_ULOG is loaded before
nfnetlink_log all NFLOG rules are treated as plain LOG rules.
