Starting from 3.6 we cache output routes for
multicasts only when using route to 224/4. For local receivers
we can set RTCF_LOCAL flag depending on the membership but
in such case we use maddr and saddr which are not caching
keys as before. Additionally, we can not use same place to
cache routes that differ in RTCF_LOCAL flag value.
Fix it by caching only RTCF_MULTICAST entries
without RTCF_LOCAL (send-only, no loopback). As a side effect,
we avoid unneeded lookup for fnhe when not caching because
multicasts are not redirected and they do not learn PMTU.
Thanks to Maxime Bizon for showing the caching
problems in __mkroute_output for 3.6 kernels: different
RTCF_LOCAL flag in cache can lead to wrong ip_mc_output or
ip_output call and the visible problem is that traffic can
not reach local receivers via loopback.

The following patchset contains two Netfilter fixes:
* Fix buffer overflow in the name of the timeout policy object
in the cttimeout infrastructure, from Florian Westphal.
* Fix a bug in the hash set in case that IP ranges are
specified, from Jozsef Kadlecsik.

Chen Gang reports:
the length of nla_data(cda[CTA_TIMEOUT_NAME]) is not limited in server side.
And indeed, its used to strcpy to a fixed-sized buffer.
Fortunately, nfnetlink users need CAP_NET_ADMIN.

Due to the missing ininitalization at adding/deleting entries, when
a plain_ip,port,net element was the object, multiple elements were
added/deleted instead. The bug came from the missing dangling
default initialization.
The error-prone default initialization is corrected in all hash:* types.

The xfrm gc threshold value depends on ip_rt_max_size. This
value was set to INT_MAX with the routing cache removal patch,
so we start doing garbage collecting when we have INT_MAX/2
IPsec routes cached. Fix this by going back to the static
threshold of 1024 routes.

John W. Linville says:
====================
This is a batch of fixes intended for 3.7...
Included are two pulls. Regarding the mac80211 tree, Johannes says:
"Please pull my mac80211.git tree (see below) to get two more fixes for
3.7. Both fix regressions introduced *before* this cycle that weren't
noticed until now, one for IBSS not cleaning up properly and the other
to add back the "wireless" sysfs directory for Fedora's startup scripts."
Regarding the iwlwifi tree, Johannes says:
"Please also pull my iwlwifi.git tree, I have two fixes: one to remove a
spurious warning that can actually trigger in legitimate situations, and
the other to fix a regression from when monitor mode was changed to use
the "sniffer" firmware mode."
Also included is an nfc tree pull. Samuel says:
"We mostly have pn533 fixes here, 2 memory leaks and an early unlocking fix.
Moreover, we also have an LLCP adapter linked list insertion fix."
On top of that, a few more bits... Albert Pool adds a USB ID
to rtlwifi. Bing Zhao provides two mwifiex fixes -- one to fix
a system hang during a command timeout, and the other to properly
report a suspend error to the MMC core. Finally, Sujith Manoharan
fixes a thinko that would trigger an ath9k hang during device reset.

Fedora's networking scripts, they check for the existence of the
wireless directory. As the files aren't used, add the directory
back and not the files. Also do it for both drivers based on the
old wireless extensions and cfg80211, regardless of whether the
compat code for wext is built into cfg80211 or not.

The check whether the IBSS is active and can be removed should be
performed before deinitializing the fields used for the check/search.
Otherwise, the configured BSS will not be found and removed properly.
To make it more clear for the future, rename sdata->u.ibss to the
local pointer ifibss which is used within the checks.

John W. Linville says:
====================
This batch of fixes is intended for the 3.7 stream...
This includes a pull of the Bluetooth tree. Gustavo says:
"A few important fixes to go into 3.7. There is a new hw support by Marcos
Chaparro. Johan added a memory leak fix and hci device index list fix.
Also Marcel fixed a race condition in the device set up that was prevent the
bt monitor to work properly. Last, Paulo Sérgio added a fix to the error
status when pairing for LE fails. This was prevent userspace to work to handle
the failure properly."
Regarding the mac80211 pull, Johannes says:
"I have a locking fix for some SKB queues, a variable initialization to
avoid crashes in a certain failure case, another free_txskb fix from
Felix and another fix from him to avoid calling a stopped driver, a fix
for a (very unlikely) memory leak and a fix to not send null data
packets when resuming while not associated."
Regarding the iwlwifi pull, Johannes says:
"Two more fixes for iwlwifi ... one to use ieee80211_free_txskb(), and
one to check DMA mapping errors, please pull."
On top of that, Johannes also included a wireless regulatory fix
to allow 40 MHz on channels 12 and 13 in world roaming mode. Also,
Hauke Mehrtens fixes a #ifdef typo in brcmfmac.

It is important that the monitor interface gets notified about
a new device before its power on procedure has been started.
For some reason that is no longer working as expected and the power
on procedure runs first. It is safe to just notify about device
registration and trigger the power on procedure afterwards.

When pairing fails due to wrong confirm value, the management layer
doesn't report a proper error status. It sends
MGMT_STATUS_CONNECT_FAILED instead of MGMT_STATUS_AUTH_FAILED.
Most of management functions that receive a status as a parameter
expects for it to be encoded as a HCI status. But when a SMP pairing
fails, the SMP layer sends the SMP reason as the error status to the
management layer.
This commit maps all SMP reasons to HCI_ERROR_AUTH_FAILURE, which will
be converted to MGMT_STATUS_AUTH_FAILED in the management layer.

The mgmt_read_index_list uses one loop to calculate the max needed size
of its response with the help of an upper-bound of the controller count.
The second loop is more strict as it checks for HCI_SETUP (which might
have gotten set after the first loop) and could result in some indexes
being skipped. Because of this the function needs to readjust the event
length and index count after filling in the response array.

On resume or firmware recovery, mac80211 sends a null
data packet to see if the AP is still around and hasn't
disconnected us. However, it always does this even if
it wasn't even connected before, leading to a warning
in the new channel context code. Fix this by checking
that it's associated.

Included fixes are:
- update the client entry status flags when using the "early client
detection". This makes the Distributed AP isolation correctly work;
- transfer the client entry status flags when recovering the translation
table from another node. This makes the Distributed AP isolation correctly
work;
- prevent the "early client detection mechanism" to add clients belonging to
other backbone nodes in the same LAN. This breaks connectivity when using this
mechanism together with the Bridge Loop Avoidance
- process broadcast packets with the Bridge Loop Avoidance before any other
component. BLA can possibly drop the packets based on the source address. This
makes the "early client detection mechanism" correctly work when used with
BLA.

The logic in the BLA mechanism may decide to drop broadcast packets
because the node may still be in the setup phase. For this reason,
further broadcast processing like the early client detection mechanism
must be done only after the BLA check.
This patches moves the invocation to BLA before any other broadcast
processing.

Flags carried by a change_entry have to be always copied into the
client entry as they may contain important attributes (e.g.
TT_CLIENT_WIFI).
For instance, a client added by means of the "early detection
mechanism" has no flag set at the beginning, so they must be updated once the
proper ADD event is received.

Currently if a socket was repaired with a few packet in a write queue,
a kernel bug may be triggered:
kernel BUG at net/ipv4/tcp_output.c:2330!
RIP: 0010:[<ffffffff8155784f>] tcp_retransmit_skb+0x5ff/0x610
According to the initial realization v3.4-rc2-963-gc0e88ff,
all skb-s should look like already posted. This patch fixes code
according with this sentence.
Here are three points, which were not done in the initial patch:
1. A tcp send head should not be changed
2. Initialize TSO state of a skb
3. Reset the retransmission time
This patch moves logic from tcp_sendmsg to tcp_write_xmit. A packet
passes the ussual way, but isn't sent to network. This patch solves
all described problems and handles tcp_sendpages.

Commit 13d782f ("sctp: Make the proc files per network namespace.")
changed the /proc/net/sctp/ struct file_operations opener functions to
use single_open_net() and seq_open_net().
Avoid leaking memory by using single_release_net() and seq_release_net()
as the release functions.
Discovered with Trinity (the syscall fuzzer).

With the latest kernel there are two things that must be done post decryption
so that the packet are forwarded.
1. Remove the mark from the packet. This will cause the packet to not match
the ipsec-policy again. However doing this causes the post-decryption check to
fail also and the packet will get dropped. (cat /proc/net/xfrm_stat).
2. Remove the sp association in the skbuff so that no policy check is done on
the packet for VTI tunnels.
Due to #2 above we must now do a security-policy check in the vti rcv path
prior to resetting the mark in the skbuff.

We added support for RFC 5961 in latest kernels but TCP fails
to perform exhaustive check of ACK sequence.
We can update our view of peer tsval from a frame that is
later discarded by tcp_ack()
This makes timestamps enabled sessions vulnerable to injection of
a high tsval : peers start an ACK storm, since the victim
sends a dupack each time it receives an ACK from the other peer.
As tcp_validate_incoming() is called before tcp_ack(), we should
not peform tcp_replace_ts_recent() from it, and let callers do it
at the right time.

(1<<optname) is undefined behavior in C with a negative optname or
optname larger than 31. In those cases the result of the shift is
not necessarily zero (e.g., on x86).
This patch simplifies the code with a switch statement on optname.
It also allows the compiler to generate better code (e.g., using a
64-bit mask).

Pull networking fixes from David Miller:
"Bug fixes galore, mostly in drivers as is often the case:
1) USB gadget and cdc_eem drivers need adjustments to their frame size
lengths in order to handle VLANs correctly. From Ian Coolidge.
2) TIPC and several network drivers erroneously call tasklet_disable
before tasklet_kill, fix from Xiaotian Feng.
3) r8169 driver needs to apply the WOL suspend quirk to more chipsets,
fix from Cyril Brulebois.
4) Fix multicast filters on RTL_GIGA_MAC_VER_35 r8169 chips, from
Nathan Walp.
5) FDB netlink dumps should use RTM_NEWNEIGH as the message type, not
zero. From John Fastabend.
6) Fix smsc95xx tx checksum offload on big-endian, from Steve
Glendinning.
7) __inet_diag_dump() needs to repsect and report the error value
returned from inet_diag_lock_handler() rather than ignore it.
Otherwise if an inet diag handler is not available for a particular
protocol, we essentially report success instead of giving an error
indication. Fix from Cyrill Gorcunov.
8) When the QFQ packet scheduler sees TSO/GSO packets it does not
handle things properly, and in fact ends up corrupting it's
datastructures as well as mis-schedule packets. Fix from Paolo
Valente.
9) Fix oopser in skb_loop_sk(), from Eric Leblond.
10) CXGB4 passes partially uninitialized datastructures in to FW
commands, fix from Vipul Pandya.
11) When we send unsolicited ipv6 neighbour advertisements, we should
send them to the link-local allnodes multicast address, as per
RFC4861. Fix from Hannes Frederic Sowa.
12) There is some kind of bug in the usbnet's kevent deferral
mechanism, but more immediately when it triggers an uncontrolled
stream of kernel messages spam the log. Rate limit the error log
message triggered when this problem occurs, as sending thousands
of error messages into the kernel log doesn't help matters at all,
and in fact makes further diagnosis more difficult.
From Steve Glendinning.
13) Fix gianfar restore from hibernation, from Wang Dongsheng.
14) The netlink message attribute sizes are wrong in the ipv6 GRE
driver, it was using the size of ipv4 addresses instead of ipv6
ones :-) Fix from Nicolas Dichtel."

Due to a NULL dereference, the following patch is causing oops

af_packet: don't emit packet on orig fanout group
This buggy patch was a feature fix and has reached most stable
branches.
When skb->sk is NULL and when packet fanout is used, there is a
crash in match_fanout_group where skb->sk is accessed.
This patch fixes the issue by returning false as soon as the
socket is NULL: this correspond to the wanted behavior because
the kernel as to resend the skb to all the listening socket in
this case.

If the max packet size for some class (configured through tc) is
violated by the actual size of the packets of that class, then QFQ
would not schedule classes correctly, and the data structures
implementing the bucket lists may get corrupted. This problem occurs
with TSO/GSO even if the max packet size is set to the MTU, and is,
e.g., the cause of the failure reported in [1]. Two patches have been
proposed to solve this problem in [2], one of them is a preliminary
version of this patch.
This patch addresses the above issues by: 1) setting QFQ parameters to
proper values for supporting TSO/GSO (in particular, setting the
maximum possible packet size to 64KB), 2) automatically increasing the
max packet size for a class, lmax, when a packet with a larger size
than the current value of lmax arrives.
The drawback of the first point is that the maximum weight for a class
is now limited to 4096, which is equal to 1/16 of the maximum weight
sum.
Finally, this patch also forcibly caps the timestamps of a class if
they are too high to be stored in the bucket list. This capping, taken
from QFQ+ [3], handles the unfrequent case described in the comment to
the function slot_insert.

We've observed that in case if UDP diag module is not
supported in kernel the netlink returns NLMSG_DONE without
notifying a caller that handler is missed.
This patch makes __inet_diag_dump to return error code instead.
So as example it become possible to detect such situation
and handle it gracefully on userspace level.

Change the dflt fdb dump handler to use RTM_NEWNEIGH to
be compatible with bridge dump routines.
The dump reply from the network driver handlers should
match the reply from bridge handler. The fact they were
not in the ixgbe case was effectively a bug. This patch
resolves it.
Applications that were not checking the nlmsg type will
continue to work. And now applications that do check
the type will work as expected.
