The recent refactoring of the IGMP and MLD parsing code into
ipv6_mc_check_mld() / ip_mc_check_igmp() introduced a potential crash /
BUG() invocation for bridges:
I wrongly assumed that skb_get() could be used as a simple reference
counter for an skb which is not the case. skb_get() bears additional
semantics, a user count. This leads to a BUG() invocation in
pskb_expand_head() / kernel panic if pskb_may_pull() is called on an skb
with a user count greater than one - unfortunately the refactoring did
just that.
Fixing this by removing the skb_get() call and changing the API: The
caller of ipv6_mc_check_mld() / ip_mc_check_igmp() now needs to
additionally check whether the returned skb_trimmed is a clone.

====================
Netfilter updates for net-next
The following patchset contains Netfilter updates for net-next, they are:
1) A couple of cleanups for the netfilter core hook from Eric Biederman.
2) Net namespace hook registration, also from Eric. This adds a dependency with
the rtnl_lock. This should be fine by now but we have to keep an eye on this
because if we ever get the per-subsys nfnl_lock before rtnl we have may
problems in the future. But we have room to remove this in the future by
propagating the complexity to the clients, by registering hooks for the init
netns functions.
3) Update nf_tables to use the new net namespace hook infrastructure, also from
Eric.
4) Three patches to refine and to address problems from the new net namespace
hook infrastructure.
5) Switch to alternate jumpstack in xtables iff the packet is reentering. This
only applies to a very special case, the TEE target, but Eric Dumazet
reports that this is slowing down things for everyone else. So let's only
switch to the alternate jumpstack if the tee target is in used through a
static key. This batch also comes with offline precalculation of the
jumpstack based on the callchain depth. From Florian Westphal.
6) Minimal SCTP multihoming support for our conntrack helper, from Michal
Kubecek.
7) Reduce nf_bridge_info per skbuff scratchpad area to 32 bytes, from Florian
Westphal.
8) Fix several checkpatch errors in bridge netfilter, from Bernhard Thaler.
9) Get rid of useless debug message in ip6t_REJECT, from Subash Abhinov.

Before this patch when a vid was not specified, the entry was added with
vid 0 which is useless when vlan_filtering is enabled. This patch makes
the entry to be added on all configured vlans when vlan filtering is
enabled and respectively deleted from all, if the entry vid is 0.
This is also closer to the way fdb works with regard to vid 0 and vlan
filtering.
Example:
Setup:
$ bridge vlan add vid 256 dev eth4
$ bridge vlan add vid 1024 dev eth4
$ bridge vlan add vid 64 dev eth3
$ bridge vlan add vid 128 dev eth3
$ bridge vlan
port vlan ids
eth3 1 PVID Egress Untagged
64
128
eth4 1 PVID Egress Untagged
256
1024
$ echo 1 > /sys/class/net/br0/bridge/vlan_filtering
Before:
$ bridge mdb add dev br0 port eth3 grp 239.0.0.1
$ bridge mdb
dev br0 port eth3 grp 239.0.0.1 temp
After:
$ bridge mdb add dev br0 port eth3 grp 239.0.0.1
$ bridge mdb
dev br0 port eth3 grp 239.0.0.1 temp vid 1
dev br0 port eth3 grp 239.0.0.1 temp vid 128
dev br0 port eth3 grp 239.0.0.1 temp vid 64

Since mdb states were introduced when deleting an entry the state was
left as it was set in the delete request from the user which leads to
the following output when doing a monitor (for example):
$ bridge mdb add dev br0 port eth3 grp 239.0.0.1 permanent
(monitor) dev br0 port eth3 grp 239.0.0.1 permanent
$ bridge mdb del dev br0 port eth3 grp 239.0.0.1 permanent
(monitor) dev br0 port eth3 grp 239.0.0.1 temp
^^^
Note the "temp" state in the delete notification which is wrong since
the entry was permanent, the state in a delete is always reported as
"temp" regardless of the real state of the entry.
After this patch:
$ bridge mdb add dev br0 port eth3 grp 239.0.0.1 permanent
(monitor) dev br0 port eth3 grp 239.0.0.1 permanent
$ bridge mdb del dev br0 port eth3 grp 239.0.0.1 permanent
(monitor) dev br0 port eth3 grp 239.0.0.1 permanent
There's one important note to make here that the state is actually not
matched when doing a delete, so one can delete a permanent entry by
stating "temp" in the end of the command, I've chosen this fix in order
not to break user-space tools which rely on this (incorrect) behaviour.
So to give an example after this patch and using the wrong state:
$ bridge mdb add dev br0 port eth3 grp 239.0.0.1 permanent
(monitor) dev br0 port eth3 grp 239.0.0.1 permanent
$ bridge mdb del dev br0 port eth3 grp 239.0.0.1 temp
(monitor) dev br0 port eth3 grp 239.0.0.1 permanent
Note the state of the entry that got deleted is correct in the
notification.

There are several devices that can receive vlan tagged packets with
CHECKSUM_PARTIAL like tap, possibly veth and xennet.
When (multiple) vlan tagged packets with CHECKSUM_PARTIAL are forwarded
by bridge to a device with the IP_CSUM feature, they end up with checksum
error because before entering bridge, the network header is set to
ETH_HLEN (not including vlan header length) in __netif_receive_skb_core(),
get_rps_cpu(), or drivers' rx functions, and nobody fixes the pointer later.
Since the network header is exepected to be ETH_HLEN in flow-dissection
and hash-calculation in RPS in rx path, and since the header pointer fix
is needed only in tx path, set the appropriate network header on forwarding
packets.

These should be handled only by the respective STP which is in control.
They become problematic for devices with limited resources with many
ports because the hold_timer is per port and fires each second and the
hello timer fires each 2 seconds even though it's global. While in
user-space STP mode these timers are completely unnecessary so it's better
to keep them off.
Also ensure that when the bridge is up these timers are started only when
running with kernel STP.

Since slave_changelink support was added there have been a few race
conditions when using br_setport() since some of the port functions it
uses require the bridge lock. It is very easy to trigger a lockup due to
some internal spin_lock() usage without bh disabled, also it's possible to
get the bridge into an inconsistent state.

====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for your net tree. This batch
mostly comes with patches to address fallout from the previous merge window
cycle, they are:
1) Use entry->state.hook_list from nf_queue() instead of the global nf_hooks
which is not valid when used from NFPROTO_NETDEV, this should cause no
problems though since we have no userspace queueing for that family, but
let's fix this now for the sake of correctness. Patch from Eric W. Biederman.
2) Fix compilation breakage in bridge netfilter if CONFIG_NF_DEFRAG_IPV4 is not
set, from Bernhard Thaler.
3) Use percpu jumpstack in arptables too, now that there's a single copy of the
rule blob we can't store the return address there anymore. Patch from
Florian Westphal.
4) Fix a skb leak in the xmit path of bridge netfilter, problem there since
2.6.37 although it should be not possible to hit invalid traffic there, also
from Florian.
5) Eric Leblond reports that when loading a large ruleset with many missing
modules after a fresh boot, nf_tables can take long time commit it. Fix this
by processing the full batch until the end, even on missing modules, then
abort only once and restart processing.
6) Add bridge netfilter files to the MAINTAINER files.
7) Fix a net_device refcount leak in the new IPV6 bridge netfilter code, from
Julien Grall.

Since commit b0e9a30dd669 ("bridge: Add vlan id to multicast groups")
there's a check in br_ip_equal() for a matching vlan id, but the mdb
functions were not modified to use (or at least zero it) so when an
entry was added it would have a garbage vlan id (from the local br_ip
variable in __br_mdb_add/del) and this would prevent it from being
matched and also deleted. So zero out the whole local ip var to protect
ourselves from future changes and also to fix the current bug, since
there's no vlan id support in the mdb uapi - use always vlan id 0.
Example before patch:
root@debian:~# bridge mdb add dev br0 port eth1 grp 239.0.0.1 permanent
root@debian:~# bridge mdb
dev br0 port eth1 grp 239.0.0.1 permanent
root@debian:~# bridge mdb del dev br0 port eth1 grp 239.0.0.1 permanent

The commit efb6de9b4ba0092b2c55f6a52d16294a8a698edd "netfilter: bridge:
forward IPv6 fragmented packets" introduced a new function
br_validate_ipv6 which take a reference on the inet6 device. Although,
the reference is not released at the end.
This will result to the impossibility to destroy any netdevice using
ipv6 and bridge.
It's possible to directly retrieve the inet6 device without taking a
reference as all netfilter hooks are protected by rcu_read_lock via
nf_hook_slow.

Add a new argument to br_fdb_delete_by_port which allows to specify a
vid to match when flushing entries and use it in nbp_vlan_delete() to
flush the dynamically learned entries of the vlan/port pair when removing
a vlan from a port. Before this patch only the local mac was being
removed and the dynamically learned ones were left to expire.
Note that the do_all argument is still respected and if specified, the
vid will be ignored.

Add a comment to explain why we're not disabling port's multicast when it
goes in blocking state. Since there's a check in the timer's function which
bypasses the timer if the port's in blocking/disabled state, the timer will
simply expire and stop without sending more queries.

When STP is running in user-space and querier is configured, the
querier timer is not started when a port goes to a non-blocking state.
This patch unifies the user- and kernel-space stp multicast port enable
path and enables it in all states different from blocking. Note that when a
port goes in BR_STATE_DISABLED it's not enabled because that is handled
in the beginning of the port list loop.
