Remove the switch block in l2tp_nl_cmd_session_create() that
checks pseudowire-specific parameters since just L2TP_PWTYPE_ETH and
L2TP_PWTYPE_PPP are currently supported and no actual checks are
performed. Moreover the L2TP_PWTYPE_IP/default case presents a harmless
issue in error handling (break instead of goto out_tunnel)

l2tp: set l2specific_len based on l2specific_type
Do not rely on l2specific_len value provided by userspace but set sublayer
length according to l2specific_type.
Mark L2TP_ATTR_L2SPEC_LEN attribute as not used
Changes since v2:
- drop the patch related to a fix in the switch default case in
l2tp_nl_cmd_session_create()
- use L2SPECTYPE_NONE as default case in l2tp_get_l2specific_len()
Changes since v1:
- remove l2specific_len parameter
- add sanity check on l2specific_type provided by userspace

Remove l2specific_len dependency while building l2tpv3 header or
parsing the received frame since default L2-Specific Sublayer is
always four bytes long and we don't need to rely on a user supplied
value.
Moreover in l2tp netlink code there are no sanity checks to
enforce the relation between l2specific_len and l2specific_type,
so sending a malformed netlink message is possible to set
l2specific_type to L2TP_L2SPECTYPE_DEFAULT (or even
L2TP_L2SPECTYPE_NONE) and set l2specific_len to a value greater than
4 leaking memory on the wire and sending corrupted frames.

peernet2id_alloc() is racy without rtnl_lock() as refcount_read(&peer->count)
under net->nsid_lock does not guarantee, peer is alive:
rcu_read_lock()
peernet2id_alloc() ..
spin_lock_bh(&net->nsid_lock) ..
refcount_read(&peer->count) (!= 0) ..
.. put_net()
.. cleanup_net()
.. for_each_net(tmp)
.. spin_lock_bh(&tmp->nsid_lock)
.. __peernet2id(tmp, net) == -1
.. ..
.. ..
__peernet2id_alloc(alloc == true) ..
.. ..
rcu_read_unlock() ..
.. synchronize_rcu()
.. kmem_cache_free(net)
After the above situation, net::netns_id contains id pointing to freed memory,
and any other dereferencing by the id will operate with this freed memory.
Currently, peernet2id_alloc() is used under rtnl_lock() everywhere except
ovs_vport_cmd_fill_info(), and this race can't occur. But peernet2id_alloc()
is generic interface, and better we fix it before someone really starts
use it in wrong context.

====================
net: sched: allow qdiscs to share filter block instances
Currently the filters added to qdiscs are independent. So for example if you
have 2 netdevices and you create ingress qdisc on both and you want to add
identical filter rules both, you need to add them twice. This patchset
makes this easier and mainly saves resources allowing to share all filters
within a qdisc - I call it a "filter block". Also this helps to save
resources when we do offload to hw for example to expensive TCAM.
So back to the example. First, we create 2 qdiscs. Both will share
block number 22. "22" is just an identification:
$ tc qdisc add dev ens7 ingress_block 22 ingress
^^^^^^^^^^^^^^^^
$ tc qdisc add dev ens8 ingress_block 22 ingress
^^^^^^^^^^^^^^^^
If we don't specify "block" command line option, no shared block would
be created:
$ tc qdisc add dev ens9 ingress
Now if we list the qdiscs, we will see the block index in the output:
$ tc qdisc
qdisc ingress ffff: dev ens7 parent ffff:fff1 ingress_block 22
qdisc ingress ffff: dev ens8 parent ffff:fff1 ingress_block 22
qdisc ingress ffff: dev ens9 parent ffff:fff1
To make is more visual, the situation looks like this:
ens7 ingress qdisc ens7 ingress qdisc
| |
| |
+----------> block 22 <----------+
Unlimited number of qdiscs may share the same block.
Note that this patchset introduces block sharing support also for clsact
qdisc:
$ tc qdisc add dev ens10 ingress_block 23 egress_block 24 clsact
$ tc qdisc show dev ens10
qdisc clsact ffff: dev ens10 parent ffff:fff1 ingress_block 23 egress_block 24
We can add filter using the block index:
$ tc filter add block 22 protocol ip pref 25 flower dst_ip 192.168.0.0/16 action drop
Note we cannot use the qdisc for filter manipulations of shared blocks:
$ tc filter add dev ens8 ingress protocol ip pref 1 flower dst_ip 192.168.100.2 action drop
Error: This filter block is shared. Please use the block index to manipulate the filters.
We will see the same output if we list filters for ingress qdisc of
ens7 and ens8, also for the block 22:
$ tc filter show block 22
filter block 22 protocol ip pref 25 flower chain 0
filter block 22 protocol ip pref 25 flower chain 0 handle 0x1
...
$ tc filter show dev ens7 ingress
filter block 22 protocol ip pref 25 flower chain 0
filter block 22 protocol ip pref 25 flower chain 0 handle 0x1
...
$ tc filter show dev ens8 ingress
filter block 22 protocol ip pref 25 flower chain 0
filter block 22 protocol ip pref 25 flower chain 0 handle 0x1
...

Introduce two new attributes to be used for qdisc creation and dumping.
One for ingress block, one for egress block. Introduce a set of ops that
qdisc which supports block sharing would implement.
Passing block indexes in qdisc change is not supported yet and it is
checked and forbidded.
In future, these attributes are to be reused for specifying block
indexes for classes as well. As of this moment however, it is not
supported so a check is in place to forbid it.

As the tcm_ifindex with value TCM_IFINDEX_MAGIC_BLOCK is invalid ifindex,
use it to indicate that we work with block, instead of qdisc.
So if tcm_ifindex is set to TCM_IFINDEX_MAGIC_BLOCK, tcm_parent is used
to carry block_index.
If the block is set to be shared between at least 2 qdiscs, it is
forbidden to use the qdisc handle to add/delete filters. In that case,
userspace has to pass block_index.
Also, for dump of the filters, in case the block is shared in between at
least 2 qdiscs, the each filter is dumped with tcm_ifindex value
TCM_IFINDEX_MAGIC_BLOCK and tcm_parent set to block_index. That gives
the user clear indication, that the filter belongs to a shared block
and not only to one qdisc under which it is dumped.

Allow qdiscs to share filter blocks among them. Each qdisc type has to
use block get/put extended modifications that enable sharing.
Shared blocks are tracked within each net namespace and identified
by u32 index. This index is passed from user during the qdisc creation.
If user passes index that is not used by any other qdisc, new block
is created. If user passes index that is already used, the existing
block will be re-used.

So far, there was possible only to register a single filter chain
pointer to block->chain[0]. However, when the blocks will get shareable,
we need to allow multiple filter chain pointers registration.

====================
bnxt_en: Updates for net-next.
First, we upgrade the firmware interface spec. Due to a change in
the toolchains, the auto-generated bnxt_hsi.h does not match the
old bnxt_hsi.h and the patch is really big. This should be just
one-time. Going forward, changes should be incremental.
The next 10 patches implement a new scheme for the PF and VF drivers
to allocate and reserve resources. The new scheme is more flexible
and allows dynamic and asymmetric distribution of resources, whereas
the old scheme is static and even distribution.
The last few patches add cacheline size setting, a couple of PCI IDs,
better management of VF MAC address, and a better parent switchdev ID
for dual-port devices.

Currently the driver exports different switchdev PARENT_IDs for
representors belonging to different SR-IOV PF-pools of an adapter.
This is not correct as the adapter can switch across all vports
of an adapter. This patch fixes this by exporting a common switchdev
PARENT_ID for all reps of an adapter. The PCIE DSN is used as the id.

The chip supports 64-byte and 128-byte cache line size for more optimal
DMA performance when matched to the CPU cache line size. The default is 64.
If the system is using 128-byte cache line size, set it to 128.
