bc818ce2d5 drivers/net/wan/hdlc_cisco: Add hard_header_len
[ Upstream commit 1a545ebe380bf4c1433e3c136e35a77764fda5ad ]

This driver didn't set hard_header_len. This patch sets hard_header_len
for it according to its header_ops->create function.

This driver's header_ops->create function (cisco_hard_header) creates
a header of (struct hdlc_header), so hard_header_len should be set to
sizeof(struct hdlc_header).

0aa356dde9 drivers/net/wan/lapbether: Set network_header before transmitting
[ Upstream commit 91244d108441013b7367b3b4dcc6869998676473 ]

Set the skb's network_header before it is passed to the underlying
Ethernet device for transmission.

This patch fixes the following issue:

When we use this driver with AF_PACKET sockets, there would be error
messages of:
   protocol 0805 is buggy, dev (Ethernet interface name)
printed in the system "dmesg" log.

This is because skbs passed down to the Ethernet device for transmission
don't have their network_header properly set, and the dev_queue_xmit_nit
function in net/core/dev.c complains about this.

Reason of setting the network_header to this place (at the end of the
Ethernet header, and at the beginning of the Ethernet payload):

Because when this driver receives an skb from the Ethernet device, the
network_header is also set at this place.

983efe173e net: hns3: Fix for geneve tx checksum bug
[ Upstream commit a156998fc92d3859c8e820f1583f6d0541d643c3 ]

when skb->encapsulation is 0, skb->ip_summed is CHECKSUM_PARTIAL
and it is udp packet, which has a dest port as the IANA assigned.
the hardware is expected to do the checksum offload, but the
hardware will not do the checksum offload when udp dest port is
6081.

This patch fixes it by doing the checksum in software.

0faee7f8c2 drivers/net/wan/lapbether: Added needed_tailroom
[ Upstream commit 1ee39c1448c4e0d480c5b390e2db1987561fb5c2 ]

The underlying Ethernet device may request necessary tailroom to be
allocated by setting needed_tailroom. This driver should also set
needed_tailroom to request the tailroom needed by the underlying
Ethernet device to be allocated.

commit a092b7233f0e000cc6f2c71a49e2ecc6f917a5fc upstream.

The buffer size is 2 Bytes and we expect to receive the same amount of
data. But sometimes we receive less data and run into uninit-was-stored
issue upon read. Hence modify the error check on the return value to match
with the buffer size as a prevention.

1a7e03867a tg3: Fix soft lockup when tg3_reset_task() fails.
[ Upstream commit 556699341efa98243e08e34401b3f601da91f5a3 ]

If tg3_reset_task() fails, the device state is left in an inconsistent
state with IFF_RUNNING still set but NAPI state not enabled.  A
subsequent operation, such as ifdown or AER error can cause it to
soft lock up when it tries to disable NAPI state.

Fix it by bringing down the device to !IFF_RUNNING state when
tg3_reset_task() fails.  tg3_reset_task() running from workqueue
will now call tg3_close() when the reset fails.  We need to
modify tg3_reset_task_cancel() slightly to avoid tg3_close()
calling cancel_work_sync() to cancel tg3_reset_task().  Otherwise
cancel_work_sync() will wait forever for tg3_reset_task() to
finish.

[ Upstream commit eb0f3bc463d59d86402f19c59aa44e82dc3fab6d ]

We recently added some calls to clk_disable_unprepare() but we missed
the last error path if register_netdev() fails.

I made a couple cleanups so we avoid mistakes like this in the future.
First I reversed the "if (!ret)" condition and pulled the code in one
indent level.  Also, the "port->netdev = NULL;" is not required because
"port" isn't used again outside this function so I deleted that line.

8227199cea bnxt_en: fix HWRM error when querying VF temperature
[ Upstream commit 12cce90b934bf2b0ed9c339b4d5503e69954351a ]

Firmware returns RESOURCE_ACCESS_DENIED for HWRM_TEMP_MONITORY_QUERY for
VFs. This produces unpleasing error messages in the log when temp1_input
is queried via the hwmon sysfs interface from a VF.

The error is harmless and expected, so silence it and return unknown as
the value. Since the device temperature is not particularly sensitive
information, provide flexibility to change this policy in future by
silencing the error rather than avoiding the HWRM call entirely for VFs.

[ Upstream commit b148bb238c02f0c7797efed026e9bba5892d2172 ]

bnxt_fw_reset_task() is run from a delayed workqueue.  The current
code is not cancelling the workqueue in the driver's .remove()
method and it can potentially crash if the device is removed with
the workqueue still pending.

The fix is to clear the BNXT_STATE_IN_FW_RESET flag and then cancel
the delayed workqueue in bnxt_remove_one().  bnxt_queue_fw_reset_work()
also needs to check that this flag is set before scheduling.  This
will guarantee that no rescheduling will be done after it is cancelled.

[ Upstream commit 99d469fc64d06f0c81c0fe2a1c01645a67e0cbf0 ]

To flush the vid + mc entries from ALE, which is required when a VLAN
interface is removed, driver needs to call cpsw_ale_flush_multicast()
with ALE_PORT_HOST for port mask as these entries are added only for
host port. Without this, these entries remain in the ALE table even
after removing the VLAN interface. cpsw_ale_flush_multicast() calls
cpsw_ale_flush_mcast which expects a port mask to do the job.

When this driver is built as a module, I cannot rmmod it after insmoding

This is because that this driver calls ravb_mdio_init() at the time of

after that.
Therefore, even if ifup is not performed, the driver is in use and rmmod
cannot be performed.

c656534e5c macvlan: validate setting of multiple remote source MAC addresses
[ Upstream commit 8b61fba503904acae24aeb2bd5569b4d6544d48f ]

Remote source MAC addresses can be set on a 'source mode' macvlan
interface via the IFLA_MACVLAN_MACADDR_DATA attribute. This commit
tightens the validation of these MAC addresses to match the validation
already performed when setting or adding a single MAC address via the
IFLA_MACVLAN_MACADDR attribute.

iproute2 uses IFLA_MACVLAN_MACADDR_DATA for its 'macvlan macaddr set'
command, and IFLA_MACVLAN_MACADDR for its 'macvlan macaddr add' command,
which demonstrates the inconsistent behaviour that this commit
addresses:

 # ip link add link eth0 name macvlan0 type macvlan mode source
 # ip link set link dev macvlan0 type macvlan macaddr add 01:00:00:00:00:00
 RTNETLINK answers: Cannot assign requested address
 # ip link set link dev macvlan0 type macvlan macaddr set 01:00:00:00:00:00
 # ip -d link show macvlan0

[ Upstream commit a1769bb68a850508a492e3674ab1e5e479b11254 ]

This reverts commit 76d164f582150fd0259ec0fcbc485470bcd8033e.
PCIe hung issue was observed on multiple platforms. The issue was reproduced
when DUT was configured as AP and associated with 50+ STAs.

For QCA9984/QCA9888, the DMA_BURST_SIZE register controls the AXI burst size
of the RD/WR access to the HOST MEM.
0 - No split , RAW read/write transfer size from MAC is put out on bus
    as burst length
1 - Split at 256 byte boundary
2,3 - Reserved

With PCIe protocol analyzer, we can see DMA Read crossing 4KB boundary when
issue happened. It broke PCIe spec and caused PCIe stuck. So revert
the default value from 0 to 1.

Tested:  IPQ8064 + QCA9984 with firmware 10.4-3.10-00047
         QCS404 + QCA9984 with firmware 10.4-3.9.0.2--00044

f4adc6430d net: ena: Prevent reset after device destruction
[ Upstream commit 63d4a4c145cca2e84dc6e62d2ef5cb990c9723c2 ]

The reset work is scheduled by the timer routine whenever it
detects that a device reset is required (e.g. when a keep_alive signal
is missing).
When releasing device resources in ena_destroy_device() the driver
cancels the scheduling of the timer routine without destroying the reset
work explicitly.

This creates the following bug:
    The driver is suspended and the ena_suspend() function is called
	-> This function calls ena_destroy_device() to free the net device
	   resources
	    -> The driver waits for the timer routine to finish
	    its execution and then cancels it, thus preventing from it
	    to be called again.

    If, in its final execution, the timer routine schedules a reset,
    the reset routine might be called afterwards,and a redundant call to
    ena_restore_device() would be made.

By changing the reset routine we allow it to read the device's state
accurately.
This is achieved by checking whether ENA_FLAG_TRIGGER_RESET flag is set
before resetting the device and making both the destruction function and
the flag check are under rtnl lock.
The ENA_FLAG_TRIGGER_RESET is cleared at the end of the destruction
routine. Also surround the flag check with 'likely' because
we expect that the reset routine would be called only when
ENA_FLAG_TRIGGER_RESET flag is set.

The destruction of the timer and reset services in __ena_shutoff() have to
stay, even though the timer routine is destroyed in ena_destroy_device().
This is to avoid a case in which the reset routine is scheduled after
free_netdev() in __ena_shutoff(), which would create an access to freed
memory in adapter->flags.

f4ed9ede34 bonding: fix active-backup failover for current ARP slave
[ Upstream commit 0410d07190961ac526f05085765a8d04d926545b ]

When the ARP monitor is used for link detection, ARP replies are
validated for all slaves (arp_validate=3) and fail_over_mac is set to
active, two slaves of an active-backup bond may get stuck in a state
where both of them are active and pass packets that they receive to
the bond. This state makes IPv6 duplicate address detection fail. The
state is reached thus:
1. The current active slave goes down because the ARP target
   is not reachable.
2. The current ARP slave is chosen and made active.
3. A new slave is enslaved. This new slave becomes the current active
   slave and can reach the ARP target.
As a result, the current ARP slave stays active after the enslave
action has finished and the log is littered with "PROBE BAD" messages:
> bond0: PROBE: c_arp ens10 && cas ens11 BAD
The workaround is to remove the slave with "going back" status from
the bond and re-enslave it. This issue was encountered when DPDK PMD
interfaces were being enslaved to an active-backup bond.

I would be possible to fix the issue in bond_enslave() or
bond_change_active_slave() but the ARP monitor was fixed instead to
keep most of the actions changing the current ARP slave in the ARP
monitor code. The current ARP slave is set as inactive and backup
during the commit phase. A new state, BOND_LINK_FAIL, has been
introduced for slaves in the context of the ARP monitor. This allows
administrators to see how slaves are rotated for sending ARP requests
and attempts are made to find a new active slave.

When we tear down a network namespace, we unregister all
the netdevices within it. So we may queue a slave device
and a bonding device together in the same unregister queue.

If the only slave device is non-ethernet, it would
automatically unregister the bonding device as well. Thus,
we may end up unregistering the bonding device twice.

Workaround this special case by checking reg_state.

e2a8d44236 i40e: Set RX_ONLY mode for unicast promiscuous on VLAN
[ Upstream commit 4bd5e02a2ed1575c2f65bd3c557a077dd399f0e8 ]

Trusted VF with unicast promiscuous mode set, could listen to TX
traffic of other VFs.
Set unicast promiscuous mode to RX traffic, if VSI has port VLAN
configured. Rename misleading I40E_AQC_SET_VSI_PROMISC_TX bit to
I40E_AQC_SET_VSI_PROMISC_RX_ONLY. Aligned unicast promiscuous with
VLAN to the one without VLAN.

c173511a12 net: wan: wanxl: use $(M68KCC) instead of $(M68KAS) for rebuilding firmware
commit 734f3719d3438f9cc181d674c33ca9762e9148a1 upstream.

The firmware source, wanxlfw.S, is currently compiled by the combo of
$(CPP) and $(M68KAS). This is not what we usually do for compiling *.S
files. In fact, this Makefile is the only user of $(AS) in the kernel
build.

Instead of combining $(CPP) and (AS) from different tool sets, using
$(M68KCC) as an assembler driver is simpler, and saner.

c7c239c947 net: wan: wanxl: use allow to pass CROSS_COMPILE_M68k for rebuilding firmware
commit 63b903dfebdea92aa92ad337d8451a6fbfeabf9d upstream.

As far as I understood from the Kconfig help text, this build rule is
used to rebuild the driver firmware, which runs on an old m68k-based
chip. So, you need m68k tools for the firmware rebuild.

wanxl.c is a PCI driver, but CONFIG_M68K does not select CONFIG_HAVE_PCI.
So, you cannot enable CONFIG_WANXL_BUILD_FIRMWARE for ARCH=m68k. In other
words, ifeq ($(ARCH),m68k) is false here.

I am keeping the dead code for now, but rebuilding the firmware requires
'as68k' and 'ld68k', which I do not have in hand.

Instead, the kernel.org m68k GCC [1] successfully built it.

Allowing a user to pass in CROSS_COMPILE_M68K= is handier.

[ Upstream commit 393415203f5c916b5907e0a7c89f4c2c5a9c5505 ]

We need to increase TSO_HEADER_SIZE from 128 to 256.

Since otx2_sq_init() calls qmem_alloc() with TSO_HEADER_SIZE,
we need to change (struct qmem)->entry_sz to avoid truncation to 0.

6ea125ec64 net: stmmac: dwmac1000: provide multicast filter fallback
commit 592d751c1e174df5ff219946908b005eb48934b3 upstream.

If we don't have a hardware multicast filter available then instead of
silently failing to listen for the requested ethernet broadcast
addresses fall back to receiving all multicast packets, in a similar
fashion to other drivers with no multicast filter.

e92a02e47e net: ethernet: stmmac: Disable hardware multicast filter
commit df43dd526e6609769ae513a81443c7aa727c8ca3 upstream.

The IPQ806x does not appear to have a functional multicast ethernet
address filter. This was observed as a failure to correctly receive IPv6
packets on a LAN to the all stations address. Checking the vendor driver
shows that it does not attempt to enable the multicast filter and
instead falls back to receiving all multicast packets, internally
setting ALLMULTI.

Use the new fallback support in the dwmac1000 driver to correctly
achieve the same with the mainline IPQ806x driver. Confirmed to fix IPv6
functionality on an RB3011 router.

8a337428a5 vmxnet3: use correct tcp hdr length when packet is encapsulated
[ Upstream commit 8a7f280f29a80f6e0798f5d6e07c5dd8726620fe ]

Commit dacce2be3312 ("vmxnet3: add geneve and vxlan tunnel offload
support") added support for encapsulation offload. However, while
calculating tcp hdr length, it does not take into account if the
packet is encapsulated or not.

This patch fixes this issue by using correct reference for inner
tcp header.
