The GRE conflict is between a bug fix (kfree_skb --> kfree_skb_list)
and the splitting of the gre.c code into seperate files.
The FEC conflict was two sets of changes adding ethtool support code
in an "!CONFIG_M5272" CPP protected block.
Finally the sh_eth.c conflict was between one commit add bits set
in the .eesr_err_check mask whilst another commit removed the
.tx_error_check member and assignments.

The parameter of setup_timer should be &ulog->nlgroup[i].
the incorrect parameter will cause kernel panic in
ulog_timer.
Bug introducted in commit 355430671a
"netfilter: ipt_ULOG: add net namespace support for ipt_ULOG"
ebt_ULOG doesn't have this problem.

Conflicts:

The conflict in nf_log.c is that in 'net' we added CONFIG_PROC_FS
protection around foo_proc_entry() calls to fix a build failure,
whereas in Pablo's tree a guard if() test around a call is
remove_proc_entry() was removed. Trivially resolved.

====================
The following patchset contains the first batch of
Netfilter/IPVS updates for your net-next tree, they are:
* Three patches with improvements and code refactorization
for nfnetlink_queue, from Florian Westphal.
* FTP helper now parses replies without brackets, as RFC1123
recommends, from Jeff Mahoney.
* Rise a warning to tell everyone about ULOG deprecation,
NFLOG has been already in the kernel tree for long time
and supersedes the old logging over netlink stub, from
myself.
* Don't panic if we fail to load netfilter core framework,
just bail out instead, from myself.
* Add cond_resched_rcu, used by IPVS to allow rescheduling
while walking over big hashtables, from Simon Horman.
* Change type of IPVS sysctl_sync_qlen_max sysctl to avoid
possible overflow, from Zhang Yanfei.
* Use strlcpy instead of strncpy to skip zeroing of already
initialized area to write the extension names in ebtables,
from Chen Gang.
* Use already existing per-cpu notrack object from xt_CT,
from Eric Dumazet.
* Save explicit socket lookup in xt_socket now that we have
early demux, also from Eric Dumazet.

Merge 'net' bug fixes into 'net-next' as we have patches
that will build on top of them.
This merge commit includes a change from Emil Goode
(emilgoode@gmail.com) that fixes a warning that would
have been introduced by this merge. Specifically it
fixes the pingv6_ops method ipv6_chk_addr() to add a
"const" to the "struct net_device *dev" argument and
likewise update the dummy_ipv6_chk_addr() declaration.

If nf_log uses ipt_ULOG as logging output, we can deliver non-null
terminated strings to user-space since the maximum length of the
prefix that is passed by nf_log is NF_LOG_PREFIXLEN but pm->prefix
is 32 bytes long (ULOG_PREFIX_LEN).
This is actually happening already from nf_conntrack_tcp if ipt_ULOG
is used, since it is passing strings longer than 32 bytes.

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

Adding struct net *net in call to nf_logfn() will secure that
there always is a vaild net ptr.

The e{uid,gid} --> {uid,gid} credentials fix conflicted with the
cleanup in net-next to now pass cred structs around.
The be2net driver had a bug fix in 'net' that overlapped with the VLAN
interface changes by Patrick McHardy in net-next.
An IGB conflict existed because in 'net' the build_skb() support was
reverted, and in 'net-next' there was a comment style fix within that
code.
Several batman-adv conflicts were resolved by making sure that all
calls to batadv_is_my_mac() are changed to have a new bat_priv first
argument.
Eric Dumazet's TS ECR fix in TCP in 'net' conflicted with the F-RTO

IN=br.qemu SRC=192.168.2.1 DST=192.168.2.255 [ .. ]
(netfilter bugzilla #814).
Problem is that network stack arranges for the locally generated broadcasts
to appear on the interface they were sent out, so the IFF_LOOPBACK check
doesn't trigger.
As -m rpfilter is restricted to PREROUTING, we can check for existing
rtable instead, it catches locally-generated broad/multicast case, too.

Add copyright statements to all netfilter files which have had significant
changes done by myself in the past.
Some notes:
- nf_conntrack_ecache.c was incorrectly attributed to Rusty and Netfilter
Core Team when it got split out of nf_conntrack_core.c. The copyrights
even state a date which lies six years before it was written. It was
written in 2005 by Harald and myself.
- net/ipv{4,6}/netfilter.c, net/netfitler/nf_queue.c were missing copyright
statements. I've added the copyright statement from net/netfilter/core.c,
where this code originated
- for nf_conntrack_proto_tcp.c I've also added Jozsef, since I didn't want
it to give the wrong impression

Propagate routing errors from ip_route_me_harder() when dropping a packet

# ip ru add fwmark 0x1 lookup 100
# iptables -t mangle -A OUTPUT -d 8.8.8.8 -j MARK --set-mark 0x1

The following patchset contains Netfilter and IPVS updates for
your net-next tree, most relevantly they are:
* Add net namespace support to NFLOG, ULOG and ebt_ulog and NFQUEUE.
The LOG and ebt_log target has been also adapted, but they still
depend on the syslog netnamespace that seems to be missing, from
Gao Feng.
* Don't lose indications of congestion in IPv6 fragmentation handling,
from Hannes Frederic Sowa.i
* IPVS conversion to use RCU, including some code consolidation patches
and optimizations, also some from Julian Anastasov.

This patch adds netns support to nf_log and it prepares netns
support for existing loggers. It is composed of four major
changes.
1) nf_log_register has been split to two functions: nf_log_register
and nf_log_set. The new nf_log_register is used to globally
register the nf_logger and nf_log_set is used for enabling
pernet support from nf_loggers.
Per netns is not yet complete after this patch, it comes in
separate follow up patches.
2) Add net as a parameter of nf_log_bind_pf. Per netns is not
yet complete after this patch, it only allows to bind the
nf_logger to the protocol family from init_net and it skips
other cases.
3) Adapt all nf_log_packet callers to pass netns as parameter.
After this patch, this function only works for init_net.
4) Make the sysctl net/netfilter/nf_log pernet.
