commit 4b5ebccc40843104d980f0714bc86bfcd5568941 upstream.
When receiving an "individually addressed" action frame, the
receiver is required to return it to the sender. mac80211
gets this wrong as it also returns group addressed (mcast)
frames to the sender. Fix this and update the reference to
the new 802.11 standards version since things were shuffled
around significantly.

commit 88a9e31c506c00c8b7a2f1611406d0e38dcb33b3 upstream.
ieee80211_set_disassoc() clears ifmgd->bssid before
building DELBA frames, resulting in frames with invalid
bssid ("00:00:00:00:00:00").
Fix it by clearing ifmgd->bssid only after building
all the needed frames.
After this change, we no longer need to save the
bssid (before clearing it), so remove the local array.

commit 5870adc68fc39d81089f1e80efdf64b97e5c37a1 upstream.
bug introduced with 59b699cdee039d75915c354da06937102d1f9a84
If the source or destination mac address of an ethernet packet
could not be found in the translation table the packet was
dropped if AP isolation was turned on. This behavior would
make it impossible to send broadcast packets over the mesh as
the broadcast address will never enter the translation table.

commit 2c995ff892313009e336ecc8ec3411022f5b1c39 upstream.
skb_linearize(skb) possibly rearranges the skb internal data and then changes
the skb->data pointer value. For this reason any other pointer in the code that
was assigned skb->data before invoking skb_linearise(skb) must be re-assigned.
In the current tt_query message handling code this is not done and therefore, in
case of skb linearization, the pointer used to handle the packet header ends up
in pointing to free'd memory.
This bug was introduced by a73105b8d4c765d9ebfb664d0a66802127d8e4c7

commit fe20b39ec32e975f1054c0b7866c873a954adf05 upstream.
reg_timeout_work() calls restore_regulatory_settings() which
takes cfg80211_mutex.
reg_set_request_processed() already holds cfg80211_mutex
before calling cancel_delayed_work_sync(reg_timeout),
so it might deadlock.
Call the async cancel_delayed_work instead, in order
to avoid the potential deadlock.
This is the relevant lockdep warning:

[ Upstream commit 62b1a8ab9b3660bb820d8dfe23148ed6cda38574 ]
Orphaning skb in dev_hard_start_xmit() makes bonding behavior
unfriendly for applications sending big UDP bursts : Once packets
pass the bonding device and come to real device, they might hit a full
qdisc and be dropped. Without orphaning, the sender is automatically
throttled because sk->sk_wmemalloc reaches sk->sk_sndbuf (assuming
sk_sndbuf is not too big)
We could try to defer the orphaning adding another test in
dev_hard_start_xmit(), but all this seems of little gain,
now that BQL tends to make packets more likely to be parked
in Qdisc queues instead of NIC TX ring, in cases where performance
matters.

[ Upstream commit 954fba0274058d27c7c07b5ea07c41b3b7477894 ]
Bogdan Hamciuc diagnosed and fixed following bug in netpoll_send_udp() :
"skb->len += len;" instead of "skb_put(skb, len);"
Meaning that _if_ a network driver needs to call skb_realloc_headroom(),
only packet headers would be copied, leaving garbage in the payload.
However the skb_realloc_headroom() must be avoided as much as possible
since it requires memory and netpoll tries hard to work even if memory
is exhausted (using a pool of preallocated skbs)
It appears netpoll_send_udp() reserved 16 bytes for the ethernet header,
which happens to work for typicall drivers but not all.
Right thing is to use LL_RESERVED_SPACE(dev)
(And also add dev->needed_tailroom of tailroom)
This patch combines both fixes.
Many thanks to Bogdan for raising this issue.

[ Upstream commit d189634ecab947c10f6f832258b103d0bbfe73cc ]
/proc/net/ipv6_route reflects the contents of fib_table_hash. The proc
handler is installed in ip6_route_net_init() whereas fib_table_hash is
allocated in fib6_net_init() _after_ the proc handler has been installed.
This opens up a short time frame to access fib_table_hash with its pants
down.
Move the registration of the proc files to a later point in the init
order to avoid the race.
Tested :-)

commit 71ecfa1893034eeb1c93e02e22ee2ad26d080858 upstream.
When any interface goes down, it could be the one that we
were doing a remain-on-channel with. We therefore need to
cancel the remain-on-channel and flush the related work
structs so they don't run after the interface has been
removed or even destroyed.
It's also possible in this case that an off-channel SKB
was never transmitted, so free it if this is the case.
Note that this can also happen if the driver finishes
the off-channel period without ever starting it.

[ Upstream commit c51ce49735c183ef2592db70f918ee698716276b ]
An application may call connect() to disconnect a socket using an
address with family AF_UNSPEC. The L2TP IP sockets were not handling
this case when the socket is not bound and an attempt to connect()
using AF_UNSPEC in such cases would result in an oops. This patch
addresses the problem by protecting the sk_prot->disconnect() call
against trying to unhash the socket before it is bound.
The patch also adds more checks that the sockaddr supplied to bind()
and connect() calls is valid.

[ Upstream commit 0c1833797a5a6ec23ea9261d979aa18078720b74 ]
Since commit ad0081e43a
"ipv6: Fragment locally generated tunnel-mode IPSec6 packets as needed"
the fragment of packets is incorrect.
because tunnel mode needs IPsec headers and trailer for all fragments,
while on transport mode it is sufficient to add the headers to the
first fragment and the trailer to the last.
so modify mtu and maxfraglen base on ipsec mode and if fragment is first
or last.
with my test,it work well(every fragment's size is the mtu)
and does not trigger slow fragment path.
Changes from v1:
though optimization, mtu_prev and maxfraglen_prev can be delete.
replace xfrm mode codes with dst_entry's new frag DST_XFRM_TUNNEL.
add fuction ip6_append_data_mtu to make codes clearer.

xprt_alloc_slot will call rpc_delay() to make the task wait a bit before
retrying when it gets back an -ENOMEM error from xprt_dynamic_alloc_slot.
The problem is that rpc_delay will clear the task->tk_status, causing

The solution is simply to let call_reserveresult handle the ENOMEM error
directly.

commit 80007efeff0568375b08faf93c7aad65602cb97e upstream.
It has happened twice now where elaborate troubleshooting has
undergone on systems where CONFIG_CFG80211_INTERNAL_REGDB [0]
has been set but yet net/wireless/db.txt was not updated.
Despite the documentation on this it seems system integrators could
use some more help with this, so throw out a kernel warning at boot time
when their database is empty.
This does mean that the error-prone system integrator won't likely
realize the issue until they boot the machine but -- it does not seem
to make sense to enable a build bug breaking random build testing.

Since recent changes on TCP splicing (starting with commits 2f533844
"tcp: allow splice() to build full TSO packets" and 35f9c09f "tcp:
tcp_sendpages() should call tcp_push() once"), I started seeing
massive stalls when forwarding traffic between two sockets using
splice() when pipe buffers were larger than socket buffers.
Latest changes (net: netdev_alloc_skb() use build_skb()) made the
problem even more apparent.
The reason seems to be that if do_tcp_sendpages() fails on out of memory
condition without being able to send at least one byte, tcp_push() is not
called and the buffers cannot be flushed.
After applying the attached patch, I cannot reproduce the stalls at all
and the data rate it perfectly stable and steady under any condition
which previously caused the problem to be permanent.
The issue seems to have been there since before the kernel migrated to
git, which makes me think that the stalls I occasionally experienced
with tux during stress-tests years ago were probably related to the
same issue.
This issue was first encountered on 3.0.31 and 3.2.17, so please backport
to -stable.

It fixes L2CAP socket based security level elevation during a
connection. The HID profile needs this (for keyboards) and it is the only
way to achieve the security level elevation when using the management
interface to talk to the kernel (hence the management enabling patch
being the one that exposes this issue).
It enables the userspace a security level change when the socket is
already connected and create a way to notify the socket the result of the
request. At the moment of the request the socket is made non writable, if
the request fails the connections closes, otherwise the socket is made
writable again, POLL_OUT is emmited.

This reverts commit 8a83a00b0735190384a348156837918271034144.
It causes regressions for S390 devices, because it does an
unconditional DST drop on SKBs for vlans and the QETH device
needs the neighbour entry hung off the DST for certain things
on transmit.
Arnd can't remember exactly why he even needed this change.

Due to RCU lookups and RCU based release, fib_info objects can
be found during lookup which have fi->fib_dead set.
We must ignore these entries, otherwise we risk dereferencing
the parts of the entry which are being torn down.

When the kernel validates set TCP/UDP port actions, it looks at
the ports in the existing flow to make sure that the L4 header exists.
However, these actions always use the IPv4 version of the struct.
Following patch fixes this by checking for flow ip protocol first.

Pull networking fixes from David Miller:
1) Transfer padding was wrong for full-speed USB in ASIX driver, fix
from Ingo van Lil.
2) Propagate the negative packet offset fix into the PowerPC BPF JIT.
From Jan Seiffert.
3) dl2k driver's private ioctls were letting unprivileged tasks make
MII writes and other ugly bits like that. Fix from Jeff Mahoney.
4) Fix TX VLAN and RX packet drops in ucc_geth, from Joakim Tjernlund.
5) OOPS and network namespace fixes in IPVS from Hans Schillstrom and
Julian Anastasov.
6) Fix races and sleeping in locked context bugs in drop_monitor, from
Neil Horman.
7) Fix link status indication in smsc95xx driver, from Paolo Pisati.
8) Fix bridge netfilter OOPS, from Peter Huang.
9) L2TP sendmsg can return on error conditions with the socket lock
held, oops. Fix from Sasha Levin.
10) udp_diag should return meaningful values for socket memory usage,
from Shan Wei.
11) Eric Dumazet is so awesome he gets his own section:
Socket memory cgroup code (I never should have applied those
patches, grumble...) made erroneous changes to
sk_sockets_allocated_read_positive(). It was changed to
use percpu_counter_sum_positive (which requires BH disabling)
instead of percpu_counter_read_positive (which does not).
Revert back to avoid crashes and lockdep warnings.
Adjust the default tcp_adv_win_scale and tcp_rmem[2] values
to fix throughput regressions. This is necessary as a result
of our more precise skb->truesize tracking.
Fix SKB leak in netem packet scheduler.
12) New device IDs for various bluetooth devices, from Manoj Iyer,
AceLan Kao, and Steven Harms.
13) Fix command completion race in ipw2200, from Stanislav Yakovlev.
14) Fix rtlwifi oops on unload, from Larry Finger.
15) Fix hard_mtu when adjusting hard_header_len in smsc95xx driver.
From Stephane Fillod.
16) ehea driver registers it's IRQ before all the necessary state is
setup, resulting in crashes. Fix from Thadeu Lima de Souza
Cascardo.
17) Fix PHY connection failures in davinci_emac driver, from Anatolij
Gustschin.
18) Missing break; in switch statement in bluetooth's
hci_cmd_complete_evt(). Fix from Szymon Janc.
19) Fix queue programming in iwlwifi, from Johannes Berg.
20) Interrupt throttling defaults not being actually programmed into the
hardware, fix from Jeff Kirsher and Ying Cai.
21) TLAN driver SKB encoding in descriptor busted on 64-bit, fix from
Benjamin Poirier.
22) Fix blind status block RX producer pointer deref in TG3 driver, from
Matt Carlson.
23) Promisc and multicast are busted on ehea, fixes from Thadeu Lima de
Souza Cascardo.
24) Fix crashes in 6lowpan, from Alexander Smirnov.
25) tcp_complete_cwr() needs to be careful to not rewind the CWND to
ssthresh if ssthresh has the "infinite" value. Fix from Yuchung
Cheng.
