Intel Wired LAN Driver Updates
This series contains updates to i40e and i40evf.
Greg provides two patches for i40e, the first adds the netdev ops to support
the addition of static FDB entries in the physical function (PF) MAC/VLAN
filter table so that the virtual functions (VFs) can communicate with
bridged virtual Ethernet ports such as those provided by the virtio
driver. The second is to fix an issue where the assignment of a port
VLAN after it is already up and running requires the VF driver to be
reloaded, so print a message warning the host administrator about the
need to reload the VF driver. In addition, knock the VF offline so that
it does not continue to receive traffic not on the port VLAN assigned to
it.
Jesse provides a patch for i40e and i40evf to unhide and enable the
PREFENA field in the receive host memory cache (RX-HMC) for best
performance.
Mitch provides a i40e patch to implement the net device op for Tx
bandwidth setting.
Catherine removes a firmware workaround that is no longer needed with
the latest firmware for i40e. She also provides some minor cleanups
as well bumps the driver versions.
Anjali provides a fix for i40e displaying IPv4 flow director filters
which needed additional information to be communicated up above in
order for it to be displayed correctly.
Shannon adds tracking of the NVM busy state so that the driver won't
allow a new NVM update command until a completion event is received
from the current update. Updates the admin queue API to reflect
recent changes in the firmware. Also rearranges the "if netdev" logic
to prepare for handling non-netdev VSIs. Lastly rework the fdir
setup and tear down to use the newly created i40e_vsi_open() and
i40e_vsi_close(), which also fixes a memory leak of the FDIR queue
buffer info structs across a reset.

audit: implement multicast socket for journald
This is a patch set Eric Paris and I have been working on to add a restricted
capability read-only netlink multicast socket to kernel audit to enable
userspace clients such as systemd/journald to receive audit logs, in addition
to the bidirectional auditd userspace client.
Currently, auditd has the CAP_AUDIT_CONTROL and CAP_AUDIT_WRITE capabilities
(but uses CAP_NET_ADMIN). The CAP_AUDIT_READ capability will be added for use
by read-only AUDIT_NLGRP_READLOG multicast group clients to the kaudit
subsystem. This will remove the dependence on CAP_NET_ADMIN for the multicast
read-only socket.
Patches 1-3 provide a way for per-protocol bind functions to
signal an error and to be able to clean up after themselves.
The first netfilter cleanup patch has already been accepted by a netfilter
maintainer, though I don't see it upstream yet, so it is included for
completeness.
The second patch adds the per-protocol bind function return code to signal to
the netlink code that no further processing should be done and to undo the work
already done.
V1: This rev fixes a bug introduced by flattening the code in the last posting.
*V2: This rev moves the per-protocol bind call above the socket exposure call
and refactors out the unbind procedure.
The third provides a way per protocol to undo bind actions on DROP.
Patches 4-6 implement the audit multicast socket with capability checking.
The fourth patch adds the bind function capability check to multicast join
requests for audit.
The fifth patch adds the audit log read multicast group. An assumption has
been made that systemd/journald reside in the initial network namespace. This
could be changed to check the actual network namespace of systemd/journald
should this assumption no longer be true since audit now supports all network
namespaces. This version of the patch now directly sends the broadcast when
the packet is ready rather than waiting until it passes the queue.
The sixth checks if any clients actually exist before sending.
Since the net tree is busier than the audit tree, conflicts are more likely and
the audit patches depend on the net patches, it is proposed to have the net
tree carry this entire patchset for 3.16. Are the net maintainers ok with this?

Add a netlink multicast socket with one group to kaudit for "best-effort"
delivery to read-only userspace clients such as systemd, in addition to the
existing bidirectional unicast auditd userspace client.
Currently, auditd is intended to use the CAP_AUDIT_CONTROL and CAP_AUDIT_WRITE
capabilities, but actually uses CAP_NET_ADMIN. The CAP_AUDIT_READ capability
is added for use by read-only AUDIT_NLGRP_READLOG netlink multicast group
clients to the kaudit subsystem.
This will safely give access to services such as systemd to consume audit logs
while ensuring write access remains restricted for integrity.

Have the netlink per-protocol optional bind function return an int error code
rather than void to signal a failure.
This will enable netlink protocols to perform extra checks including
capabilities and permissions verifications when updating memberships in
multicast groups.
In netlink_bind() and netlink_setsockopt() the call to the per-protocol bind
function was moved above the multicast group update to prevent any access to
the multicast socket groups before checking with the per-protocol bind
function. This will enable the per-protocol bind function to be used to check
permissions which could be denied before making them available, and to avoid
the messy job of undoing the addition should the per-protocol bind function
fail.
The netfilter subsystem seems to be the only one currently using the
per-protocol bind function.

Added a new ancillary load (bpf call in eBPF parlance) that produces
a 32-bit random number. We are implementing it as an ancillary load
(instead of an ISA opcode) because (a) it is simpler, (b) allows easy
JITing, and (c) seems more in line with generic ISAs that do not have
"get a random number" as a instruction, but as an OS call.
The main use for this ancillary load is to perform random packet sampling.

In commit 0e280af026a5 ("tcp: introduce TCPSpuriousRtxHostQueues SNMP
counter") we added a logic to detect when a packet was retransmitted
while the prior clone was still in a qdisc or driver queue.
We are now confident we can do better, and catch the problem before
we fragment a TSO packet before retransmit, or in TLP path.
This patch fully exploits the logic by simply canceling the spurious
retransmit.
Original packet is in a queue and will eventually leave the host.
This helps to avoid network collapses when some events make the RTO
estimations very wrong, particularly when dealing with huge number of
sockets with synchronized blast.

====================
purge tipc_net_lock
Now tipc routing hierarchy comprises the structures 'node', 'link'and
'bearer'. The whole hierarchy is protected by a big read/write lock,
tipc_net_lock, to ensure that nothing is added or removed while code
is accessing any of these structures. Obviously the locking policy
makes node, link and bearer components closely bound together so that
their relationship becomes unnecessarily complex. In the worst case,
such locking policy not only has a negative influence on performance,
but also it's prone to lead to deadlock occasionally.
In order o decouple the complex relationship between bearer and node
as well as link, the locking policy is adjusted as follows:
- Bearer level
RTNL lock is used on update side, and RCU is used on read side.
Meanwhile, all bearer instances including broadcast bearer are
saved into bearer_list array.
- Node and link level
All node instances are saved into two tipc_node_list and node_htable
lists. The two lists are protected by node_list_lock on write side,
and they are guarded with RCU lock on read side. All members in node
structure including link instances are protected by node spin lock.
- The relationship between bearer and node
When link accesses bearer, it first needs to find the bearer with
its bearer identity from the bearer_list array. When bearer accesses
node, it can iterate the node_htable hash list with the node address
to find the corresponding node.
In the new locking policy, every component has its private locking
solution and the relationship between bearer and node is very simple,
that is, they can find each other with node address or bearer identity
from node_htable hash list or bearer_list array.

Commit a21a584d6720ce349b05795b9bcfab3de8e58419 (tipc: fix neighbor
detection problem after hw address change) introduces a race condition
involving tipc_disc_delete() and tipc_disc_add/remove_dest that can
cause TIPC to dereference the pointer to the bearer discovery request
structure after it has been freed since a stray pointer is left in the
bearer structure.
In order to fix the issue, the process of resetting the discovery
request handler is optimized: the discovery request handler and request
buffer are just reset instead of being freed, allocated and initialized.
As the request point is always valid and the request's lock is taken
while the request handler is reset, the race doesn't happen any more.

The node map variable - 'nodes' in bearer structure is only used by
bclink. When bclink accesses it, bc_lock is held. But when change it,
for instance, in tipc_bearer_add_dest() or tipc_bearer_remove_dest()
the bc_lock is not taken at all. To avoid any inconsistent data, we
should always grab bc_lock while accessing node map variable.

As bearer pointer is known in tipc_l2_device_event(), it's unnecessary
to search it again in tipc_disable_bearer(). If tipc_disable_bearer()

Currently on both paths of message transmission and reception, the
read lock of tipc_net_lock must be held before bearer is accessed,
while the write lock of tipc_net_lock has to be taken before bearer
is configured. Although it can ensure that bearer is always valid on
the two data paths, link and bearer is closely bound together.
So as the part of effort of removing tipc_net_lock, the locking
policy of bearer protection will be adjusted as below: on the two
data paths, RCU is used, and on the configuration path of bearer,
RTNL lock is applied.
Now RCU just covers the path of message reception. To make it possible
to protect the path of message transmission with RCU, link should not
use its stored bearer pointer to access bearer, but it should use the
bearer identity of its attached bearer as index to get bearer instance
from bearer_list array, which can help us decouple the relationship
between bearer and link. As a result, bearer on the path of message
transmission can be safely protected by RCU when we access bearer_list
array within RCU lock protection.

Currently the 'tipc_ptr' pointer is protected by tipc_net_lock
write lock on write side, and RCU read lock is applied to read
side. In addition, there have two paths on write side where we
may change variables pointed by the 'tipc_ptr' pointer: one is
to configure bearer by tipc-config tool and another one is that
bearer status is changed by notification events of its attached
interface. But on the latter path, we improperly deem that
accessing 'tipc_ptr' pointer happens on read side with
rcu_read_lock() although some variables pointed by the 'tipc_ptr'
pointer are changed possibly.
Moreover, as now the both paths are guarded by RTNL lock, it's
better to adjust the locking policy of 'tipc_ptr' pointer
protection, allowing RTNL instead of tipc_net_lock write lock to
protect it on write side, which will help us purge tipc_net_lock
in the future.

There have two paths where we can configure or change bearer status:
one is that bearer is configured from user space with tipc-config
tool; another one is that bearer is changed by notification events
from its attached interface. On the first path, one dedicated
config_mutex lock is guarded; on the latter path, RTNL lock has been
placed to serialize the process of dealing with interface events.
So, if RTNL lock is also used to protect the first path, this will
not only extremely help us simplify current locking policy, but also
config_mutex lock can be deleted as well.

Implement the net device op for Tx bandwidth setting. Setting the Tx
bandwidth is done by 'ip link set <PF device> vf <VF num> rate <Tx
rate>', with the rate specified in Mbit/sec. The rate setting is
displayed with 'ip link show'.

If a host VMM administrator hoses his VF by assigning a port VLAN after
it is already up and running with implicit permission to set local
VLANs then we print a message warning the host administrator that the
VF driver needs to be reloaded.
In addition we need to knock the VF offline so that it does not continue
to receive traffic not on the port VLAN assigned to it. So we reset the
VF. The VF will cease operation and the administrator will be forced to
unload and reload the VF driver to make it work again.

Add the netdev ops to support addition of static FDB entries in the
physical function (PF) MAC/VLAN filter table so that virtual functions
(VFs) can communicate with bridged virtual Ethernet ports such as those
provided by the virtio driver.

stmmac_config() denies changing the base address and interrupt
parameters, and ignores any other settings from the ifmap parameters,
thus making stmmac_config() useless, remove it.

sxgbe_config() denies changing the base address and interrupt, and
ignores all other 'struct ifmap' members, which means that it is useless
as is, so let's remove it.

ethoc_config() returns -ENOSYS and does not implement anything useful,
let's remove it such that net/core/dev_ioctl.c::dev_ifsioc can return
something meaningful like -EOPNOTSUPP.
