Non-GSO TCP packets whose SKBs' linear portion did not include the
entire TCP header were not populating the first Tx descriptor with
as many bytes as the vNIC expected. This change ensures that all
TCP packets populate the first descriptor with the correct number of
bytes.

If the number of lanes was forced and then subsequently the user
omits this parameter, the ksettings->lanes is reset. The driver
should then reset the number of lanes to the device's default
for the specified speed.
However, although the ksettings->lanes is set to 0, the mod variable
is not set to true to indicate the driver and userspace should be
notified of the changes.
The consequence is that the same ethtool operation will produce
different results based on the initial state.
If the initial state is:
$ ethtool swp1 | grep -A 3 'Speed: '
Speed: 500000Mb/s
Lanes: 2
Duplex: Full
Auto-negotiation: on
then executing 'ethtool -s swp1 speed 50000 autoneg off' will yield:
$ ethtool swp1 | grep -A 3 'Speed: '
Speed: 500000Mb/s
Lanes: 2
Duplex: Full
Auto-negotiation: off
While if the initial state is:
$ ethtool swp1 | grep -A 3 'Speed: '
Speed: 500000Mb/s
Lanes: 1
Duplex: Full
Auto-negotiation: off
executing the same 'ethtool -s swp1 speed 50000 autoneg off' results in:
$ ethtool swp1 | grep -A 3 'Speed: '
Speed: 500000Mb/s
Lanes: 1
Duplex: Full
Auto-negotiation: off
This patch fixes this behavior. Omitting lanes will always results in
the driver choosing the default lane width for the chosen speed. In this
scenario, regardless of the initial state, the end state will be, e.g.,
$ ethtool swp1 | grep -A 3 'Speed: '
Speed: 500000Mb/s
Lanes: 2
Duplex: Full
Auto-negotiation: off

====================
raw/ping: Fix locking in /proc/net/{raw,icmp}.
The first patch fixes a NULL deref for /proc/net/raw and second one fixes
the same issue for ping sockets.
The first patch also converts hlist_nulls to hlist, but this is because
the current code uses sk_nulls_for_each() for lockless readers, instead
of sk_nulls_for_each_rcu() which adds memory barrier, but raw sockets
does not use the nulls marker nor SLAB_TYPESAFE_BY_RCU in the first place.
OTOH, the ping sockets already uses sk_nulls_for_each_rcu(), and such
conversion can be posted later for net-next.

Let's go back to using spinlock there.
Note we can convert ping sockets to use hlist instead of hlist_nulls
because we do not use SLAB_TYPESAFE_BY_RCU for ping sockets.

In the am65_cpsw_nuss_probe() function's cleanup path, the call to
of_platform_device_destroy() for the common->mdio_dev device is invoked
unconditionally. It is possible that either the MDIO node is not present
in the device-tree, or the MDIO node is disabled in the device-tree. In
both these cases, the MDIO device is not created, resulting in a NULL
pointer dereference when the of_platform_device_destroy() function is
invoked on the common->mdio_dev device on the cleanup path.
Fix this by ensuring that the common->mdio_dev device exists, before
attempting to invoke of_platform_device_destroy().

On the remote side, when QRTR socket is removed, af_qrtr will call
qrtr_port_remove() which broadcasts the DEL_CLIENT packet to all neighbours
including local NS. NS upon receiving the DEL_CLIENT packet, will remove
the lookups associated with the node:port and broadcasts the DEL_SERVER
packet.
But on the host side, due to the arrival of the DEL_CLIENT packet, the NS
would've already deleted the server belonging to that port. So when the
remote's NS again broadcasts the DEL_SERVER for that port, it throws below
error message on the host:
"failed while handling packet from 2:-2"
So fix this error by not broadcasting the DEL_SERVER packet when the

This patch fixes a corner case where the asoc out stream count may change
after wait_for_sndbuf.
When the main thread in the client starts a connection, if its out stream
count is set to N while the in stream count in the server is set to N - 2,
another thread in the client keeps sending the msgs with stream number
N - 1, and waits for sndbuf before processing INIT_ACK.
However, after processing INIT_ACK, the out stream count in the client is
shrunk to N - 2, the same to the in stream count in the server. The crash
occurs when the thread waiting for sndbuf is awake and sends the msg in a
non-existing stream(N - 1), the call trace is as below:

Based on further tests, it seems that the QDMA shaper is not able to
perform shaping close to the MAC link rate without throughput loss.
This cannot be compensated by increasing the shaping rate, so it seems
to be an internal limit.
Fix the remaining throughput regression by detecting that condition and
limiting shaping to ports with lower link speed.
This patch intentionally ignores link speed gain from TRGMII, because
even on such links, shaping to 1000 Mbit/s incurs some throughput
degradation.

Commit 0db3dc73f7a3 ("[NETPOLL]: tx lock deadlock fix") narrowed
down the region under netif_tx_trylock() inside netpoll_send_skb().
(At that point in time netif_tx_trylock() would lock all queues of
the device.) Taking the tx lock was problematic because driver's
cleanup method may take the same lock. So the change made us hold
the xmit lock only around xmit, and expected the driver to take
care of locking within ->ndo_poll_controller().
Unfortunately this only works if netpoll isn't itself called with
the xmit lock already held. Netpoll code is careful and uses
trylock(). The drivers, however, may be using plain lock().
Printing while holding the xmit lock is going to result in rare
deadlocks.
Luckily we record the xmit lock owners, so we can scan all the queues,
the same way we scan NAPI owners. If any of the xmit locks is held
by the local CPU we better not attempt any polling.
It would be nice if we could narrow down the check to only the NAPIs
and the queue we're trying to use. I don't see a way to do that now.

Commit 7dd76d1feec70 ("dm: improve bio splitting and associated IO
accounting") only called setup_split_accounting() from
__send_duplicate_bios() if a single bio were being issued. But the case
where duplicate bios are issued must call it too.
Otherwise the bio won't be split and resubmitted (via recursion through
block core back to DM) to submit the later portions of a bio (which may
map to an entirely different target).
For example, when discarding an entire DM striped device with the
following DM table:
vg-lvol0: 0 159744 striped 2 128 7:0 2048 7:1 2048
vg-lvol0: 159744 45056 striped 2 128 7:2 2048 7:3 2048
Before (broken, discards the first striped target's devices twice):
device-mapper: striped: target_stripe=0, bdev=7:0, start=2048 len=79872
device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=79872
device-mapper: striped: target_stripe=0, bdev=7:0, start=2049 len=22528
device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=22528
After (works as expected):
device-mapper: striped: target_stripe=0, bdev=7:0, start=2048 len=79872
device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=79872
device-mapper: striped: target_stripe=0, bdev=7:2, start=2048 len=22528
device-mapper: striped: target_stripe=1, bdev=7:3, start=2048 len=22528

"Abnormal" bios include discards, write zeroes and secure erase. By no
longer passing the calculated 'len' pointer, commit 7dd06a2548b2 ("dm:
allow dm_accept_partial_bio() for dm_io without duplicate bios") took a
senseless approach to disallowing dm_accept_partial_bio() from working
for duplicate bios processed using __send_duplicate_bios().
It inadvertently and incorrectly stopped the use of 'len' when
initializing a target's io (in alloc_tio). As such the resulting tio
could address more area of a device than it should.
For example, when discarding an entire DM striped device with the
following DM table:
vg-lvol0: 0 159744 striped 2 128 7:0 2048 7:1 2048
vg-lvol0: 159744 45056 striped 2 128 7:2 2048 7:3 2048
Before this fix:
device-mapper: striped: target_stripe=0, bdev=7:0, start=2048 len=102400
blkdiscard: attempt to access beyond end of device
loop0: rw=2051, sector=2048, nr_sectors = 102400 limit=81920
device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=102400
blkdiscard: attempt to access beyond end of device
loop1: rw=2051, sector=2048, nr_sectors = 102400 limit=81920
After this fix;
device-mapper: striped: target_stripe=0, bdev=7:0, start=2048 len=79872
device-mapper: striped: target_stripe=1, bdev=7:1, start=2048 len=79872

Reported on the Turris forum, mvneta provokes kernel warnings in the
architecture DMA mapping code when mvneta_setup_txqs() fails to
allocate memory. This happens because when mvneta_cleanup_txqs() is
called in the mvneta_stop() path, we leave pointers in the structure
that have been freed.
Then on mvneta_open(), we call mvneta_setup_txqs(), which starts
allocating memory. On memory allocation failure, mvneta_cleanup_txqs()
will walk all the queues freeing any non-NULL pointers - which includes
pointers that were previously freed in mvneta_stop().
Fix this by setting these pointers to NULL to prevent double-freeing
of the same memory.

If certain conditions are met, DSA can install all necessary MAC
addresses on the CPU ports as FDB entries and disable flooding towards
the CPU (we call this RX filtering).
There is one corner case where this does not work.
ip link add br0 type bridge vlan_filtering 1 && ip link set br0 up
ip link set swp0 master br0 && ip link set swp0 up
ip link add link swp0 name swp0.100 type vlan id 100
ip link set swp0.100 up && ip addr add 192.168.100.1/24 dev swp0.100
Traffic through swp0.100 is broken, because the bridge turns on VLAN
filtering in the swp0 port (causing RX packets to be classified to the
FDB database corresponding to the VID from their 802.1Q header), and
although the 8021q module does call dev_uc_add() towards the real
device, that API is VLAN-unaware, so it only contains the MAC address,
not the VID; and DSA's current implementation of ndo_set_rx_mode() is
only for VID 0 (corresponding to FDB entries which are installed in an
FDB database which is only hit when the port is VLAN-unaware).
It's interesting to understand why the bridge does not turn on
IFF_PROMISC for its swp0 bridge port, and it may appear at first glance
that this is a regression caused by the logic in commit 2796d0c648c9
("bridge: Automatically manage port promiscuous mode."). After all,
a bridge port needs to have IFF_PROMISC by its very nature - it needs to
receive and forward frames with a MAC DA different from the bridge
ports' MAC addresses.
While that may be true, when the bridge is VLAN-aware *and* it has a
single port, there is no real reason to enable promiscuity even if that
is an automatic port, with flooding and learning (there is nowhere for
packets to go except to the BR_FDB_LOCAL entries), and this is how the
corner case appears. Adding a second automatic interface to the bridge
would make swp0 promisc as well, and would mask the corner case.
Given the dev_uc_add() / ndo_set_rx_mode() API is what it is (it doesn't
pass a VLAN ID), the only way to address that problem is to install host
FDB entries for the cartesian product of RX filtering MAC addresses and
VLAN RX filters.
