[ Upstream commit 01f8902bcf3ff124d0aeb88a774180ebcec20ace ]
Fix hardware setup of multicast address hash:
- Never clear the hardware hash (to avoid packet loss)
- Construct the hash register values in software and then write once
to hardware

[ Upstream commit e2e004acc7cbe3c531e752a270a74e95cde3ea48 ]
This fixes a crash when running out of grant refs when creating many
queues across many netdevs.
* If creating queues fails (i.e. there are no grant refs available),
call xenbus_dev_fatal() to ensure that the xenbus device is set to the
closed state.
* If no queues are created, don't call xennet_disconnect_backend as
netdev->real_num_tx_queues will not have been set correctly.
* If setup_netfront() fails, ensure that all the queues created are
cleaned up, not just those that have been set up.
* If any queues were set up and an error occurs, call
xennet_destroy_queues() to clean up the napi context.
* If any fatal error occurs, unregister and destroy the netdev to avoid
leaving around a half setup network device.

[ Upstream commit ce7e40c432ba84da104438f6799d460a4cad41bc ]
ipddp_route structs contain alignment padding so kernel heap memory
is leaked when they are copied to user space in
ipddp_ioctl(SIOCFINDIPDDPRT). Change kmalloc() to kzalloc() to clear
that memory.

[ Upstream commit 38e5a85562a6cd911fc26d951d576551a688574c ]
Inserting the TSB means adding an extra 8 bytes in front the of packet
that is going to be used as metadata information by the TDMA engine, but
stripped off, so it does not really help with the packet padding.
For some odd packet sizes that fall below the 60 bytes payload (e.g: ARP)
we can end-up padding them after the TSB insertion, thus making them 64
bytes, but with the TDMA stripping off the first 8 bytes, they could
still be smaller than 64 bytes which is required to ingress the switch.
Fix this by swapping the padding and TSB insertion, guaranteeing that
the packets have the right sizes.

[ Upstream commit bb7da333d0a9f3bddc08f84187b7579a3f68fd24 ]
Since we need to pad our packets, utilize skb_put_padto() which
increases skb->len by how much we need to pad, allowing us to eliminate
the test on skb->len right below.

[ Upstream commit 7cfe0455ee1218add152e986b89b4bb8dbeafcdd ]
The cts protection vdev parameter, in new QCA9377 TF2.0 firmware,
requires bss peer to be created for the STATION vdev type.
bss peer is being allocated by the firmware after vdev_start/_up commands.
mac80211 may call the cts protection setup at any time, so the
we needs to track the situation and defer the cts configuration
to prevent firmware asserts, like below:

[ Upstream commit 88407beb1b1462f706a1950a355fd086e1c450b6 ]
Ath10k reports the phy capability that supports P2P_DEVICE interface.
When we use the P2P supported wpa_supplicant to start connection, it'll
create two interfaces, one is wlan0 (vdev_id=0) and one is P2P_DEVICE
p2p-dev-wlan0 which is for p2p control channel (vdev_id=1).
ath10k_pci mac vdev create 0 (add interface) type 2 subtype 0
ath10k_add_interface: vdev_id: 0, txpower: 0, bss_power: 0
...
ath10k_pci mac vdev create 1 (add interface) type 2 subtype 1
ath10k_add_interface: vdev_id: 1, txpower: 0, bss_power: 0
And the txpower in per vif bss_conf will only be set to valid tx power when
the interface is assigned with channel_ctx.
But this P2P_DEVICE interface will never be used for any connection, so
that the uninitialized bss_conf.txpower=0 is assinged to the
arvif->txpower when interface created.
Since the txpower configuration is firmware per physical interface.
So the smallest txpower of all vifs will be the one limit the tx power
of the physical device, that causing the low txpower issue on other
active interfaces.
wlan0: Limiting TX power to 21 (24 - 3) dBm
ath10k_pci mac vdev_id 0 txpower 21
ath10k_mac_txpower_recalc: vdev_id: 1, txpower: 0
ath10k_mac_txpower_recalc: vdev_id: 0, txpower: 21
ath10k_pci mac txpower 0
This issue only happens when we use the wpa_supplicant that supports
P2P or if we use the iw tool to create the control P2P_DEVICE interface.

In a few cases the err-variable is not set to a negative error code if a
function call in typhoon_init_one() fails and thus 0 is returned
instead.
It may be better to set err to the appropriate negative error
code before returning.

commit 19110cfbb34d4af0cdfe14cd243f3b09dc95b013 upstream.
Lennart reported the following race condition:
\ e1000_watchdog_task
\ e1000e_has_link
\ hw->mac.ops.check_for_link() === e1000e_check_for_copper_link
/* link is up */
mac->get_link_status = false;
/* interrupt */
\ e1000_msix_other
hw->mac.get_link_status = true;
link_active = !hw->mac.get_link_status
/* link_active is false, wrongly */
This problem arises because the single flag get_link_status is used to
signal two different states: link status needs checking and link status is
down.
Avoid the problem by using the return value of .check_for_link to signal
the link status to e1000e_has_link().

commit 0a9a17e3bb4564caf4bfe2a6783ae1287667d188 upstream.
This patch fixes an issue seen on Power systems with ixgbe which results
in skb list corruption and an eventual kernel oops. The following is what
was observed:
CPU 1 CPU2
============================ ============================
1: ixgbe_xmit_frame_ring ixgbe_clean_tx_irq
2: first->skb = skb eop_desc = tx_buffer->next_to_watch
3: ixgbe_tx_map read_barrier_depends()
4: wmb check adapter written status bit
5: first->next_to_watch = tx_desc napi_consume_skb(tx_buffer->skb ..);
6: writel(i, tx_ring->tail);
The read_barrier_depends is insufficient to ensure that tx_buffer->skb does not
get loaded prior to tx_buffer->next_to_watch, which then results in loading
a stale skb pointer. This patch replaces the read_barrier_depends with
smp_rmb to ensure loads are ordered with respect to the load of
tx_buffer->next_to_watch.

commit 3f2a162fab15aee243178b5308bb5d1206fc4043 upstream.
We set rtlhal->last_suspend_sec to an uninitialized stack variable,
but unfortunately gcc never warned about this, I only found it
while working on another patch. I opened a gcc bug for this.
Presumably the value of rtlhal->last_suspend_sec is not all that
important, but it does get used, so we probably want the
patch backported to stable kernels.

commit 519ce2f933fa14acf69d5c8cabcc18711943d629 upstream.
In routine rtl92ee_set_fw_rsvdpagepkt(), the driver allocates an skb, but
never calls rtl_cmd_send_packet(), which will free the buffer. All other
rtlwifi drivers perform this operation correctly.
This problem has been in the driver since it was included in the kernel.
Fortunately, each firmware load only leaks 4 buffers, which likely
explains why it has not previously been detected.

[ Upstream commit cc54c1d32e6a4bb3f116721abf900513173e4d02 ]
This patch try to fix the building error on MIPS. The reason is MIPS
has already defined the LONG macro, which conflicts with the LONG enum
in drivers/net/ethernet/fealnx.c.

[ Upstream commit b5f862180d7011d9575d0499fa37f0f25b423b12 ]
After commit 07f4c90062f8 ("tcp/dccp: try to not exhaust ip_local_port_range
in connect()"), we will try to use even ports for connect(). Then if an
application (seen clearly with iperf) opens multiple streams to the same
destination IP and port, each stream will be given an even source port.
So the bonding driver's simple xmit_hash_policy based on layer3+4 addressing
will always hash all these streams to the same interface. And the total
throughput will limited to a single slave.
Change the tcp code will impact the whole tcp behavior, only for bonding
usage. Paolo Abeni suggested fix this by changing the bonding code only,
which should be more reasonable, and less impact.
Fix this by discarding the lowest hash bit because it contains little entropy.
After the fix we can re-balance between slaves.

A retry count of 10 is likely to run into problems on X550 devices that
have to detect and reset unresponsive CS4227 devices. So, reduce the I2C
retry count to 3 for X550 and above. This should avoid any possible
regressions in existing devices.

[ Upstream commit f7f37e7ff2b9b7eff7fbd035569cab35896869a3 ]
When an interface is part of a namespace it is possible that
ixgbe_close() may be called while __ixgbe_shutdown() is running
which ends up in a double free WARN and/or a BUG in free_msi_irqs().
To handle this situation we extend the rtnl_lock() to protect the
call to netif_device_detach() and ixgbe_clear_interrupt_scheme()
in __ixgbe_shutdown() and check for netif_device_present()
to avoid clearing the interrupts second time in ixgbe_close();
Also extend the rtnl lock in ixgbe_resume() to netif_device_attach().

Make sure that we free the IRQs in ixgbe_io_error_detected() when
responding to an PCIe AER error and also restore them when the
interface recovers from it.
Previously it was possible to trigger BUG_ON() check in free_msix_irqs()
in the case where we call ixgbe_remove() after a failed recovery from
AER error because the interrupts were not freed.

[ Upstream commit 182785335447957409282ca745aa5bc3968facee ]
Several people have reported firmware leaving the I210/I211 PHY's page
select register set to something other than the default of zero. This
causes the first accesses, PHY_IDx register reads, to access something
else, resulting in device probe failure:
igb: Intel(R) Gigabit Ethernet Network Driver - version 5.4.0-k
igb: Copyright (c) 2007-2014 Intel Corporation.
igb: probe of 0000:01:00.0 failed with error -2
This problem began for them after a previous patch I submitted was
applied:
commit 2a3cdead8b408351fa1e3079b220fa331480ffbc
Author: Aaron Sierra <asierra@xes-inc.com>
Date: Tue Nov 3 12:37:09 2015 -0600
igb: Remove GS40G specific defines/functions
I personally experienced this problem after attempting to PXE boot from
I210 devices using this firmware:
Intel(R) Boot Agent GE v1.5.78
Copyright (C) 1997-2014, Intel Corporation
Resetting the PHY before reading from it, ensures the page select
register is in its default state and doesn't make assumptions about
the PHY's register set before the PHY has been probed.

[ Upstream commit 2f3fc1e6200309ccf87f61dea56e57e563c4f800 ]
Multiple IES API resets can cause a race condition where the mailbox
interrupt request bits can be cleared before being handled. This can
leave certain mailbox messages from the PF to be untreated and the PF
will enter in some inactive state. If this situation occurs, the IES API
will initiate a mailbox version reset which, then, trigger a mailbox
state change. Once this mailbox transition occurs (from OPEN to CONNECT
state), a request for reset will be returned.
This ensures that PF will undergo a reset whenever IES API encounters an
unknown global mailbox interrupt event or whenever the IES API
terminates.

commit 9029679f66d976f8c720eb03c4898274803c9923 upstream.
Upon stopping an AP interface the driver disable INFRA mode effectively
setting the interface in IBSS mode. However, this may affect other
interfaces running in INFRA mode. For instance, if user creates and stops
hostap daemon on virtual interface, then association cannot work on
primary interface because default BSS has been set to IBSS mode in
firmware side. The IBSS mode should be set when cfg80211 changes the
interface.

[ Upstream commit 6151b8b37b119e8e3a8401b080d532520c95faf4 ]
ppp_release() tries to ensure that netdevices are unregistered before
decrementing the unit refcount and running ppp_destroy_interface().
This is all fine as long as the the device is unregistered by
ppp_release(): the unregister_netdevice() call, followed by
rtnl_unlock(), guarantee that the unregistration process completes
before rtnl_unlock() returns.
However, the device may be unregistered by other means (like
ppp_nl_dellink()). If this happens right before ppp_release() calling
rtnl_lock(), then ppp_release() has to wait for the concurrent
unregistration code to release the lock.
But rtnl_unlock() releases the lock before completing the device
unregistration process. This allows ppp_release() to proceed and
eventually call ppp_destroy_interface() before the unregistration
process completes. Calling free_netdev() on this partially unregistered
device will BUG():

We could set the ->needs_free_netdev flag on PPP devices and move the
ppp_destroy_interface() logic in the ->priv_destructor() callback. But
that'd be quite intrusive as we'd first need to unlink from the other
channels and units that depend on the device (the ones that used the
PPPIOCCONNECT and PPPIOCATTACH ioctls).
Instead, we can just let the netdevice hold a reference on its
ppp_file. This reference is dropped in ->priv_destructor(), at the very
end of the unregistration process, so that neither ppp_release() nor
ppp_disconnect_channel() can call ppp_destroy_interface() in the interim.

If the name argument of dev_get_valid_name() contains "%d", it will try
to assign it a unit number in __dev__alloc_name() and return either the
unit number (>= 0) or an error code (< 0).
Considering positive values as error values prevent tun device creations
relying this mechanism, therefor we should only consider negative values
as errors here.

[ Upstream commit 0ad646c81b2182f7fa67ec0c8c825e0ee165696d ]
register_netdevice() could fail early when we have an invalid
dev name, in which case ->ndo_uninit() is not called. For tun
device, this is a problem because a timer etc. are already
initialized and it expects ->ndo_uninit() to clean them up.
We could move these initializations into a ->ndo_init() so
that register_netdevice() knows better, however this is still
complicated due to the logic in tun_detach().
Therefore, I choose to just call dev_get_valid_name() before
register_netdevice(), which is quicker and much easier to audit.
And for this specific case, it is already enough.
