eBPF-based device cgroup controller
This patchset introduces an eBPF-based device controller for cgroup v2.

Patch (3) is the main patch, which introduces a new bpf prog type
and all necessary infrastructure.
Patch (4) moves cgroup_helpers.c/h to use them by patch (4).
Patch (5) implements an example of eBPF program which controls access

Add a test for device cgroup controller.
The test loads a simple bpf program which logs all
device access attempts using trace_printk() and forbids
all operations except operations with /dev/zero and
/dev/urandom.
Then the test creates and joins a test cgroup, and attaches
the bpf program to it.
Then it tries to perform some simple device operations
and checks the result:
create /dev/null (should fail)
create /dev/zero (should pass)
copy data from /dev/urandom to /dev/zero (should pass)
copy data from /dev/urandom to /dev/full (should fail)
copy data from /dev/random to /dev/zero (should fail)

Cgroup v2 lacks the device controller, provided by cgroup v1.
This patch adds a new eBPF program type, which in combination
of previously added ability to attach multiple eBPF programs
to a cgroup, will provide a similar functionality, but with some
additional flexibility.
This patch introduces a BPF_PROG_TYPE_CGROUP_DEVICE program type.
A program takes major and minor device numbers, device type
(block/character) and access type (mknod/read/write) as parameters
and returns an integer which defines if the operation should be
allowed or terminated with -EPERM.

mlx5-updates-2017-11-04
This series includes:
From Huy: dscp to priority mapping for Ethernet packet.
===================================================
First six patches enable differentiated services code point (dscp) to
priority mapping for Ethernet packet. Once this feature is
enabled, the packet is routed to the corresponding priority based on its
dscp. User can combine this feature with priority flow control (pfc)
feature to have priority flow control based on the dscp.
Firmware interface:
Mellanox firmware provides two control knobs for this feature:
QPTS register allow changing the trust state between dscp and
pcp mode. The default is pcp mode. Once in dscp mode, firmware will
route the packet based on its dscp value if the dscp field exists.
QPDPM register allow mapping a specific dscp (0 to 63) to a
specific priority (0 to 7). By default, all the dscps are mapped to
priority zero.
Software interface:
This feature is controlled via application priority TLV. IEEE
specification P802.1Qcd/D2.1 defines priority selector id 5 for
application priority TLV. This APP TLV selector defines DSCP to priority
map. This APP TLV can be sent by the switch or can be set locally using
software such as lldptool. In mlx5 drivers, we add the support for net
dcb's getapp and setapp call back. Mlx5 driver only handles the selector
id 5 application entry (dscp application priority application entry).
If user sends multiple dscp to priority APP TLV entries on the same
dscp, the last sent one will take effect. All the previous sent will be
deleted.
The firmware trust state (in QPTS register) is changed based on the
number of dscp to priority application entries. When the first dscp to
priority application entry is added by the user, the trust state is
changed to dscp. When the last dscp to priority application entry is
deleted by the user, the trust state is changed to pcp.
When the port is in DSCP trust state, the transmit queue is selected
based on the dscp of the skb.
When the port is in DSCP trust state and vport inline mode is not NONE,
firmware requires mlx5 driver to copy the IP header to the
wqe ethernet segment inline header if the skb has it.
This is done by changing the transmit queue sq's min inline mode to L3.
Note that the min inline mode of sqs that belong to other features
such as xdpsq, icosq are not modified.
===================================================
Plus to the dscp series, some small misc changes are include as well:
From Inbar, Ethtool msglvl support and some debug prints in DCBNL logic
From Or Gerlitz, Enlarge the NIC TC offload table size
From Rabie, Initialize destination_flow struct to 0
From Feras, Add inner TTC table to IPoIB flow steering

Recent management FW images can perform full reinit of MAC cores
without requiring a reboot. When loading the driver check if there
are changes pending and if so call NSP MAC reinit. Full application
FW reload is still required, and all MACs need to be reinited at the

potentially causing disruption to unrelated netdevs) therefore for
now changing MAC config without reloading the driver still remains

Matthias reports:
nfp_eth_set_bit_config() is marked as __always_inline to allow gcc to
identify the 'mask' parameter as known to be constant at compile time,
which is required to use the FIELD_GET() macro.
The forced inlining does the trick for gcc, but for kernel builds with
clang it results in undefined symbols:
drivers/net/ethernet/netronome/nfp/nfpcore/nfp_nsp_eth.o: In function
`__nfp_eth_set_aneg':
drivers/net/ethernet/netronome/nfp/nfpcore/nfp_nsp_eth.c:(.text+0x787):

drivers/net/ethernet/netronome/nfp/nfpcore/nfp_nsp_eth.c:(.text+0x7b1):
undefined reference to `__compiletime_assert_496'
These __compiletime_assert_xyx() calls would have been optimized away
if
the compiler had seen 'mask' as a constant.
Add a macro to extract the mask and shift and pass those to
nfp_eth_set_bit_config() separately.

Currently TCP RACK loss detection does not work well if packets are
being reordered beyond its static reordering window (min_rtt/4).Under
such reordering it may falsely trigger loss recoveries and reduce TCP
throughput significantly.
This patch improves that by increasing and reducing the reordering
window based on DSACK, which is now supported in major TCP implementations.
It makes RACK's reo_wnd adaptive based on DSACK and no. of recoveries.
- If DSACK is received, increment reo_wnd by min_rtt/4 (upper bounded
by srtt), since there is possibility that spurious retransmission was
due to reordering delay longer than reo_wnd.
- Persist the current reo_wnd value for TCP_RACK_RECOVERY_THRESH (16)
no. of successful recoveries (accounts for full DSACK-based loss
recovery undo). After that, reset it to default (min_rtt/4).
- At max, reo_wnd is incremented only once per rtt. So that the new
DSACK on which we are reacting, is due to the spurious retx (approx)
after the reo_wnd has been updated last time.
- reo_wnd is tracked in terms of steps (of min_rtt/4), rather than
absolute value to account for change in rtt.
In our internal testing, we observed significant increase in throughput,
in scenarios where reordering exceeds min_rtt/4 (previous static value).

net: dsa: parsing stage
When registering a DSA switch, there is basically two stages.
The first stage is the parsing of the switch device, from either device
tree or platform data. It fetches the DSA tree to which it belongs, and
validates its ports. The switch device is then added to the tree, and
the second stage is called if this was the last switch of the tree.
The second stage is the setup of the tree, which validates that the tree
is complete, sets up the routing tables, the default CPU port for user
ports, sets up the switch drivers and finally the master interfaces,
which makes the whole switch fabric functional.
This patch series covers the first parsing stage. It fixes the type of
the switch and tree indexes to unsigned int, simplifies the tree
reference counting and the switch and CPU ports parsing.

DSA trees have a refcount used to automatically free the dsa_switch_tree
structure once there is no switch devices inside of it.
The refcount is incremented when a switch is added to the tree, and
decremented when it is removed from it.
But because of kref_init, the refcount is also incremented at
initialization, and when looking up the tree from the list for symmetry.
Thus the current code stores the number of switches plus one, and makes
the switch registration more complex.
To simplify the switch registration function, we reset the refcount to
zero after initialization and don't increment it when looking up a tree.

Following steps are taken in the driver to offload an XDP program:
XDP_SETUP_PROG:
* prepare:
- allocate program state;
- run verifier (bpf_analyzer());
- run translation;
* load:
- stop old program if needed;
- load program;
- enable BPF if not enabled;
* clean up:
- free program image.
With new infrastructure the flow will look like this:
BPF_OFFLOAD_VERIFIER_PREP:
- allocate program state;
BPF_OFFLOAD_TRANSLATE:
- run translation;
XDP_SETUP_PROG:
- stop old program if needed;
- load program;
- enable BPF if not enabled;
BPF_OFFLOAD_DESTROY:
