77676fdbd5 openvswitch: Fix multipart datapath dumps.
The logic to split up the list of datapaths into multiple Netlink messages
was simply wrong, causing the list to be terminated after the first part.
Only about the first 50 datapaths would be dumped.  This fixes the
problem.

766e9f1be1 ipv6: fix per device IP snmp counters
In commit 4ce3c183fc (snmp: 64bit ipstats_mib for all arches), I forgot
to change the /proc/net/dev_snmp6/xxx output for IP counters.

percpu array is 64bit per counter but the folding still used the 'long'
variant, and output garbage on 32bit arches.

36c9247449 net: WARN if skb_checksum_help() is called on skb requiring segmentation
skb_checksum_help() has never done anything useful with skbs that
require segmentation.  Setting skb->ip_summed = CHECKSUM_NONE makes
them invalid and provokes a later WARNing in skb_gso_segment().

Passing such an skb to skb_checksum_help() indicates a bug, so we
should warn about it immediately.  Move the warning from
skb_gso_segment() into a shared function, and add gso_type and
gso_size to it.

74b8cc3d59 Net, mac80211: Fix resource leak in ieee80211_rx_h_mesh_fwding()
We may leak the 'fwd_skb' we skb_copy() in ieee80211_rx_h_mesh_fwding() if
we take the 'else' branch in the 'if' statement just below. If we take
that branch we'll end up returning from the function and since we've not
assigned 'fwd_skb' to anything at that point, we leak it when the variable
goes out of scope.

The simple fix seems to be to just kfree_skb(fwd_skb); just before we
return. That is what this patch does.

9bf04646b0 netfilter: revert user-space expectation helper support
This patch partially reverts:
3d058d7 netfilter: rework user-space expectation helper support
that was applied during the 3.2 development cycle.

After this patch, the tree remains just like before patch bc01bef,
that initially added the preliminary infrastructure.

I decided to partially revert this patch because the approach
that I proposed to resolve this problem is broken in NAT setups.
Moreover, a new infrastructure will be submitted for the 3.3.x
development cycle that resolve the existing issues while
providing a neat solution.

Since nobody has been seriously using this infrastructure in
user-space, the removal of this feature should affect any know
FOSS project (to my knowledge).

543d1b92d5 mac80211: fix no-op authorized transitions
When userspace attempts to authorize a station
that is already authorized, nothing happens as
you'd expect. Similarly, when it unauthorizes
a station that is associated, nothing happens.

However, when it unauthorizes a station that
isn't even associated yet, we erroneously try
to move the station to associated. This seems
to happen occasionally as a result of a race
when wpa_supplicant attempts to unauthorize
the port in managed mode. Particularly with my
new patches to keep stations, it can then move
a station into ASSOCIATED state before we have
really associated, which is really confusing.

I introduced this bug in
"mac80211: refactor station state transitions"

ddecf0f4db net_sched: sfq: add optional RED on top of SFQ
Adds an optional Random Early Detection on each SFQ flow queue.

Traditional SFQ limits count of packets, while RED permits to also
control number of bytes per flow, and adds ECN capability as well.

1) We dont handle the idle time management in this RED implementation,
since each 'new flow' begins with a null qavg. We really want to address
backlogged flows.

2) if headdrop is selected, we try to ecn mark first packet instead of
currently enqueued packet. This gives faster feedback for tcp flows
compared to traditional RED [ marking the last packet in queue ]

Example of use :

tc qdisc add dev $DEV parent 1:1 handle 10: est 1sec 4sec sfq \
	limit 3000 headdrop flows 512 divisor 16384 \
	redflowlimit 100000 min 8000 max 60000 probability 0.20 ecn

qdisc sfq 10: parent 1:1 limit 3000p quantum 1514b depth 127 headdrop
flows 512/16384 divisor 16384
 ewma 6 min 8000b max 60000b probability 0.2 ecn
 prob_mark 0 prob_mark_head 4876 prob_drop 6131
 forced_mark 0 forced_mark_head 0 forced_drop 0

requeues 0)
 rate 99483Kbit 8219pps backlog 689392b 456p requeues 0

In this test, with 64 netperf TCP_STREAM sessions, 50% using ECN enabled
flows, we can see number of packets CE marked is smaller than number of
drops (for non ECN flows)

If same test is run, without RED, we can check backlog is much bigger.

1398eee082 net: decrement memcg jump label when limit, not usage, is changed
The logic of the current code is that whenever we destroy
a cgroup that had its limit set (set meaning different than
maximum), we should decrement the jump_label counter.
Otherwise we assume it was never incremented.

But what the code actually does is test for RES_USAGE
instead of RES_LIMIT. Usage being different than maximum
is likely to be true most of the time.

The effect of this is that the key must become negative,
and since the jump_label test says:

        !!atomic_read(&key->enabled);

we'll have jump_labels still on when no one else is
using this functionality.

    mac80211: consolidate MIC failure report handling

is possible to that we dereference rx->key == NULL when driver set
RX_FLAG_MMIC_STRIPPED and not RX_FLAG_IV_STRIPPED and we are in
promiscuous mode. This happen with rt73usb and rt61pci at least.

Before the commit we always check rx->key against NULL, so I assume
fix should be done in mac80211 (also mic_fail path has similar check).

bdd3ae3d1e nl80211: fix old station flags compatibility
My patch to validate station flags broke compatibility
with the old station flags setting where all flags are
always set at once since it always set the mask as all
possible flags which ended up being rejected later in
the station add/modify code.

Fix by parsing only the current flags in the old flags
attribute -- new applications and new flags should use
(and will now require) the new flags attribute where
the mask is given by the application.

Fix up trivial conflicts in fs/9p/{vfs_inode.c,vfs_inode_dotl.c} due to
debug messages having changed to use p9_debug() on one hand, and the
changes for umode_t on the other.

Commit 5b7c840667 ('ipv4: correct IGMP
behavior on v3 query during v2-compatibility mode') added yet another
case for query parsing, which can result in max_delay = 0.  Substitute
a value of 1, as in the usual v3 case.

2429f7ac2e net: introduce netif_addr_lock_nested() and call if when appropriate
dev_uc_sync() and dev_mc_sync() are acquiring netif_addr_lock for
destination device of synchronization. Since netif_addr_lock is
already held at the time for source device, this triggers lockdep
deadlock warning.

There's no way this deadlock can happen so use spin_lock_nested() to
silence the warning.
