Subject: netfilter: nf_tables: fix wrong length for jump/goto verdicts

NFT_JUMP/GOTO erronously sets length to sizeof(void *).

We then allocate insufficient memory when such element is added to a vmap.

Currently when interface type is MAC to Phy, netif_carrier_(on/off)
is called which is not needed as Phy lib already updates the carrier
status to net stack. This is needed only for other interface types

Subject: bpf: fix 64-bit divide

ALU64_DIV instruction should be dividing 64-bit by 64-bit,
whereas do_div() does 64-bit by 32-bit divide.
x64 and arm64 JITs correctly implement 64 by 64 unsigned divide.
llvm BPF backend emits code assuming that ALU64_DIV does 64 by 64.

The commit 3cdaa5be9e81a914e633a6be7b7d2ef75b528562 ("ipv4: Don't
increase PMTU with Datagram Too Big message") broke PMTU in cases
where the rt_pmtu value has expired but is smaller than the new
PMTU value.

This obsolete rt_pmtu then prevents the new PMTU value from being
installed.

Subject: hv_netvsc: introduce netif-msg into netvsc module

1. Introduce netif-msg to netvsc to control debug logging output
and keep msg_enable in netvsc_device_context so that it is
kept persistently.
2. Only call dump_rndis_message() when NETIF_MSG_RX_ERR or above
is specified in netvsc module debug param.
In non-debug mode, in current code, dump_rndis_message() will not
dump anything but it still initialize some local variables and
process the switch logic which is unnecessary, especially in
high network throughput situation.

Subject: bnx2x: mark LRO as a fixed disabled feature if disable_tpa is set

If disable_tpa is set, remove NETIF_F_LRO from hw_features, so ethtool sees
it as "off [fixed]".

Note that setting the NETIF_F_LRO bit in dev->features in the 'else'
branch is not needed, because the bit was already set by
bnx2x_init_dev().

Then the check for disable_tpa in in bnx2x_fix_features() becomes unnecessary.

Subject: bnx2x: remove {TPA,GRO}_ENABLE_FLAG

These flags are redundant with dev->features. Remove them.
Just make sure to set dev->features ourselves in bnx2x_set_features()
before performing the reload of the card.

Subject: tipc: remove wrong use of NLM_F_MULTI

NLM_F_MULTI must be used only when a NLMSG_DONE message is sent. In fact,
it is sent only at the end of a dump.

Libraries like libnl will wait forever for NLMSG_DONE.

Subject: tipc: fix problem with parallel link synchronization mechanism

Currently, we try to accumulate arrived packets in the links's
'deferred' queue during the parallel link syncronization phase.

This entails two problems:

- With an unlucky combination of arriving packets the algorithm
  may go into a lockstep with the out-of-sequence handling function,
  where the synch mechanism is adding a packet to the deferred queue,
  while the out-of-sequence handling is retrieving it again, thus
  ending up in a loop inside the node_lock scope.

- Even if this is avoided, the link will very often send out
  unnecessary protocol messages, in the worst case leading to
  redundant retransmissions.

We fix this by just dropping arriving packets on the upcoming link
during the synchronization phase, thus relying on the retransmission
protocol to resolve the situation once the two links have arrived to
a synchronized state.

Subject: mlx4: Fix tx ring affinity_mask creation

By default, the number of tx queues is limited by the number of online cpus
in mlx4_en_get_profile(). However, this limit no longer holds after the
ethtool .set_channels method has been called. In that situation, the driver
may access invalid bits of certain cpumask variables when queue_index >=
nr_cpu_ids.

Subject: altera_tse: Correct rx packet length

Altera TSE MAC rx DMA transfer starts with the 2 additional bytes for IP
payload alignment. This patch fixes tse_rx() function loop which reads DMA
rx status and extracts packet length from it. Status signalises a whole DMA
transfer length, which is 2 bytes longer than the packet itself.

Subject: hv_netvsc: Fix a bug in netvsc_start_xmit()

Commit b08cc79155fc26d0d112b1470d1ece5034651a4b eliminated memory
allocation in the packet send path:

    "hv_netvsc: Eliminate memory allocation in the packet send path

    The network protocol used to communicate with the host is the remote ndis (rndis)
    protocol. We need to decorate each outgoing packet with a rndis header and
    additional rndis state (rndis per-packet state). To manage this state, we
    currently allocate memory in the transmit path. Eliminate this allocation by
    requesting additional head room in the skb."

This commit introduced a bug since it did not account for the case if the skb
was cloned. Fix this bug.

Subject: net: macb: Fix race condition in driver when Rx frame is dropped

Under heavy Rx load, observed that the Hw is updating the USED bit
and it is not updating the received frame status to the BD control
field. This could be lack of resources for processing the BDs at high
data rates. Driver drops the frame associated with this BD but not
clearing the USED bit. So, this is causing hang condition as Hw
expects USED bit to be cleared for this BD.

Subject: net: Fix Kernel Panic in bonding driver debugfs file: rlb_hash_table

This patch fixes a Kernel Panic in bonding driver debugfs file: rlb_hash_table.

$> modprobe bonding mode=6
$> cat /sys/kernel/debug/bonding/bond0/rlb_hash_table

This will crash the kernel. The struct alb_bond_info is initialized only when
the bonding interface is initialized (ip link set bond0 up) and not at the time
it is allocated. If we try to read the table before that, it'll result in a
kernel panic.

The patch applies against both net and net-next

Subject: bnx2x: Delay during kdump load

In a kdump environment interfaces might be re-loaded without a proper
unload sequence in the previous running kernel.
bnx2x management FW and driver maintains a `pulse' that notifies the FW
that the driver is still up and running.

Driver load on the kdump kernel should be performed only after the pulse
has been out-of-sync long enough for the management FW to identify that
the driver has crashed, on which point it will perform some necessary
cleanup of the HW.

In today's distros kdump loading is quite fast, sometimes too fast for our
FW to get out-of-sync. This patch delays the bnx2x's probe during kdump
to allow a proper re-load on the kdump kernel.

Commit 6559a7e8296002b4 ("cxgb4: Cleanup macros so they follow the same
style and look consistent") introduced a regression where reading MC1
memory in adapters where MC0 isn't present or MC0 size is not equal to MC1
size caused the adapter to crash due to incorrect computation of memoffset.
Fix is to read the size of MC0 instead of MC1 for offset calculation

While testing this driver with DEBUG_LOCKDEP and DEBUG_SPINLOCK
enabled did not produce any traces, it would be more prudent in the
case of tx_clean_lock to use spin_[un]lock_bh, since this lock is
manipulated in both the process and softirq contexts.

This patch was tested for functionality and regressions with netperf
and DEBUG_LOCKDEP and DEBUG_SPINLOCK enabled.

Subject: net/mlx4_en: Schedule napi when RX buffers allocation fails

When system is out of memory, refilling of RX buffers fails while
the driver continue to pass the received packets to the kernel stack.
At some point, when all RX buffers deplete, driver may fall into a
sleep, and not recover when memory for new RX buffers is once again
availible. This is because hardware does not have valid descriptors,
so no interrupt will be generated for the driver to return to work
in napi context. Fix it by schedule the napi poll function from
stats_task delayed workqueue, as long as the allocations fail.

Subject: net: fec: Fix RGMII-ID mode

RGMII-ID uses an internal delay within the transmitter or receiver. This
feature is phy specific. The rest of the communication is normal RGMII.

So the fec driver has to check for all RGMII modes, not only
'PHY_INTERFACE_MODE_RGMII'.

Subject: ipv4: Missing sk_nulls_node_init() in ping_unhash().

If we don't do that, then the poison value is left in the ->pprev
backlink.

This can cause crashes if we do a disconnect, followed by a connect().
