The cxgb3 driver for "Chelsio T3-based gigabit and 10Gb Ethernet
adapters" implements a custom ioctl as SIOCCHIOCTL/SIOCDEVPRIVATE in
cxgb_extension_ioctl().
One of the subcommands of the ioctl is CHELSIO_GET_MEM, which appears
to read memory directly out of the adapter and return it to userspace.
It's not entirely clear what the contents of the adapter memory
contains, but the assumption is that it shouldn't be accessible to all
users.
So add a CAP_NET_ADMIN check to the CHELSIO_GET_MEM case. Put it after
the is_offload() check, which matches two of the other subcommands in
the same function which also check for is_offload() and CAP_NET_ADMIN.

When TCP out-of-order is identified (unexpected tcp seq mismatch), driver
analyzes the packet and decides what handling should it get:
1. go to accelerated path (to be encrypted in HW),
2. go to regular xmit path (send w/o encryption),
3. drop.
Packets marked with skb->decrypted by the TLS stack in the TX flow skips
SW encryption, and rely on the HW offload.

Section 5.5.3.2 of the datasheet says,
If FIFO Underrun, Byte Count Mismatch, Excessive Collision, or
Excessive Deferral (if enabled) errors occur, transmission ceases.
In this situation, the chip asserts a TXER interrupt rather than TXDN.
But the handler for the TXDN is the only way that the transmit queue
gets restarted. Hence, an aborted transmission can result in a watchdog
timeout.
This problem can be reproduced on congested link, as that can result in
excessive transmitter collisions. Another way to reproduce this is with
a FIFO Underrun, which may be caused by DMA latency.
In event of a TXER interrupt, prevent a watchdog timeout by restarting
transmission.

Section 4.3.1 of the datasheet says,
This bit [TXP] must not be set if a Load CAM operation is in
progress (LCAM is set). The SONIC will lock up if both bits are
set simultaneously.
Testing has shown that the driver sometimes attempts to set LCAM
while TXP is set. Avoid this by waiting for command completion
before and after giving the LCAM command.
After issuing the Load CAM command, poll for !SONIC_CR_LCAM rather than
SONIC_INT_LCD, because the SONIC_CR_TXP bit can't be used until
!SONIC_CR_LCAM.
When in reset mode, take the opportunity to reset the CAM Enable
register.

There are several issues relating to command register usage during
chip initialization.
Firstly, the SONIC sometimes comes out of software reset with the
Start Timer bit set. This gets logged as,
macsonic macsonic eth0: sonic_init: status=24, i=101
Avoid this by giving the Stop Timer command earlier than later.
Secondly, the loop that waits for the Read RRA command to complete has
the break condition inverted. That's why the for loop iterates until
its termination condition. Call the helper for this instead.
Finally, give the Receiver Enable command after clearing interrupts,
not before, to avoid the possibility of losing an interrupt.

As soon as the driver is finished with a receive buffer it allocs a new
one and overwrites the corresponding RRA entry with a new buffer pointer.
Problem is, the buffer pointer is split across two word-sized registers.
It can't be updated in one atomic store. So this operation races with the
chip while it stores received packets and advances its RRP register.
This could result in memory corruption by a DMA write.
Avoid this problem by adding buffers only at the location given by the
RWP register, in accordance with the National Semiconductor datasheet.
Re-factor this code into separate functions to calculate a RRA pointer
and to update the RWP.

When giving a receive descriptor to the SONIC, clear the descriptor

The while loop in sonic_rx() traverses the rx descriptor ring. It stops
when it reaches a descriptor that the SONIC has not used. Each iteration
advances the EOL flag so the SONIC can keep using more descriptors.
Therefore, the while loop has no definite termination condition.
The algorithm described in the National Semiconductor literature is quite
different. It consumes descriptors up to the one with its EOL flag set
(which will also have its "in use" flag set). All freed descriptors are
then returned to the ring at once, by adjusting the EOL flags (and link
pointers).
Adopt the algorithm from datasheet as it's simpler, terminates quickly
and avoids a lot of pointless descriptor EOL flag changes.

The SONIC can sometimes advance its rx buffer pointer (RRP register)
without advancing its rx descriptor pointer (CRDA register). As a result
the index of the current rx descriptor may not equal that of the current
rx buffer. The driver mistakenly assumes that they are always equal.
This assumption leads to incorrect packet lengths and possible packet
duplication. Avoid this by calling a new function to locate the buffer
corresponding to a given descriptor.

The tx_aborted_errors statistic should count packets flagged with EXD,
EXC, FU, or BCM bits because those bits denote an aborted transmission.
That corresponds to the bitmask 0x0446, not 0x0642. Use macros for these
constants to avoid mistakes. Better to leave out FIFO Underruns (FU) as
there's a separate counter for that purpose.
Don't lump all these errors in with the general tx_errors counter as
that's used for tx timeout events.
On the rx side, don't count RDE and RBAE interrupts as dropped packets.
These interrupts don't indicate a lost packet, just a lack of resources.
When a lack of resources results in a lost packet, this gets reported
in the rx_missed_errors counter (along with RFO events).
Don't double-count rx_frame_errors and rx_crc_errors.
Don't use the general rx_errors counter for events that already have
special counters.

During reload (or module unload), the router block is de-initialized.
Among other things, this results in the removal of a default multicast
route from each active virtual router (VRF). These default routes are
configured during initialization to trap packets to the CPU. In
Spectrum-2, unlike Spectrum-1, multicast routes are implemented using
ACL rules.
Since the router block is de-initialized before the ACL block, it is
possible that the ACL rules corresponding to the default routes are
deleted while being accessed by the ACL delayed work that queries rules'
activity from the device. This can result in a rare use-after-free [1].
Fix this by protecting the rules list accessed by the delayed work with
a lock. We cannot use a spinlock as the activity read operation is
blocking.

In the flowtables offload all the devices in the flowtables
share the same flow_block. An offload rule will be installed on
all the devices. This scenario is not correct.
It is no problem if there are only two devices in the flowtable,
The rule with ingress and egress on the same device can be reject
by driver.
But more than two devices in the flowtable will install the wrong
rules on hardware.
For example:
Three devices in a offload flowtables: dev_a, dev_b, dev_c
A rule ingress from dev_a and egress to dev_b:
The rule will install on device dev_a.
The rule will try to install on dev_b but failed for ingress
and egress on the same device.
The rule will install on dev_c. This is not correct.
The flowtables offload avoid this case through restricting the ingress dev
with FLOW_DISSECTOR_KEY_META.
So the mlx5e driver also should support the FLOW_DISSECTOR_KEY_META parse.

====================
Mellanox, mlx5 E-Switch chains and prios
This series has two parts,
1) A merge commit with mlx5-next branch that include updates for mlx5
HW layouts needed for this and upcoming submissions.
2) From Paul, Increase the number of chains and prios
Currently the Mellanox driver supports offloading tc rules that
are defined on the first 4 chains and the first 16 priorities.
The restriction stems from the firmware flow level enforcement
requiring a flow table of a certain level to point to a flow
table of a higher level. This limitation may be ignored by setting
the ignore_flow_level bit when creating flow table entries.
Use unmanaged tables and ignore flow level to create more tables than
declared by fs_core steering. Manually manage the connections between the
tables themselves.
HW table is instantiated for every tc <chain,prio> tuple. The miss rule
of every table either jumps to the next <chain,prio> table, or continues
to slow_fdb. This logic is realized by following this sequence:
1. Create an auto-grouped flow table for the specified priority with
reserved entries
Reserved entries are allocated at the end of the flow table.

T6 can support 2 egress traffic management channels per port to
double the total number of traffic classes that can be configured.
In this configuration, if the class belongs to the other channel,
then all the queues must be bound again explicitly to the new class,
for the rate limit parameters on the other channel to take effect.
So, always explicitly bind all queues to the port rate limit traffic
class, regardless of the traffic management channel that it belongs
to. Also, only bind queues to port rate limit traffic class, if all
the queues don't already belong to an existing different traffic
class.

We would not be transmitting using the correct SYSTEMPORT transmit queue
during ndo_select_queue() which looks up the internal TX ring map
because while establishing the mapping we would be off by 4, so for
instance, when we populate switch port mappings we would be doing:
switch port 0, queue 0 -> ring index #0
switch port 0, queue 1 -> ring index #1
...
switch port 0, queue 3 -> ring index #3
switch port 1, queue 0 -> ring index #8 (4 + 4 * 1)
...
instead of using ring index #4. This would cause our ndo_select_queue()
to use the fallback queue mechanism which would pick up an incorrect
ring for that switch port. Fix this by using the correct switch queue
number instead of SYSTEMPORT queue number.

Introduce unmananged flow tables, allowing the user to manage the flow

ignore the MC TC.
Add two helpers to compute the value for logical TC from the constituents,
one for backlog, the other for tail drops. Use them throughout instead of
going through the xstats pointer directly.
Counters for TX bytes and packets are deduced from packet priority
counters, and therefore already include BUM traffic. wred_drop counter is

Per-port counter cache used by Qdiscs is updated periodically, unless the
port is down. The fact that the cache is not updated for down ports is no
problem for most counters, which are relative in nature. However, backlog
is absolute in nature, and if there is a non-zero value in the cache around
the time that the port goes down, that value just stays there. This value
then leaks to offloaded Qdiscs that report non-zero backlog even if
there (obviously) is no traffic.
The HW does not keep backlog of a downed port, so do likewise: as the port
goes down, wipe the backlog value from xstats.

The driver needs to prepend a Tx header to each packet it is
transmitting. The header includes information such as the egress port
and traffic class.
The addition of the header requires the driver to modify the SKB's
header and therefore it must not be shared. Otherwise, we risk hitting
various race conditions.
For example, when a packet is flooded (cloned) by the bridge driver to
two switch ports swp1 and swp2:
t0 - mlxsw_sp_port_xmit() is called for swp1. Tx header is prepended with
swp1's port number
t1 - mlxsw_sp_port_xmit() is called for swp2. Tx header is prepended with
swp2's port number, overwriting swp1's port number
t2 - The device processes data buffer from t0. Packet is transmitted via
swp2
t3 - The device processes data buffer from t1. Packet is transmitted via
swp2
Usually, the device is fast enough and transmits the packet before its
Tx header is overwritten, but this is not the case in emulated
environments.
Fix this by making sure the SKB's header is writable by calling
skb_cow_head(). Since the function ensures we have headroom to push the
Tx header, the check further in the function can be removed.

Previous patches added support for two hardware flags for IPv4 and IPv6
routes: 'RTM_F_OFFLOAD' and 'RTM_F_TRAP'. Both indicate the presence of
the route in hardware. The first indicates that traffic is actually
offloaded from the kernel, whereas the second indicates that packets
hitting such routes are trapped to the kernel for processing (e.g., host
routes).
Use these two flags in mlxsw. The flags are modified in two places.
Firstly, whenever a route is updated in the device's table. This
includes the addition, deletion or update of a route. For example, when
a host route is promoted to perform NVE decapsulation, its action in the
device is updated, the 'RTM_F_OFFLOAD' flag set and the 'RTM_F_TRAP'
flag cleared.
Secondly, when a route is replaced and overwritten by another route, its
flags are cleared.

Separate the offload indication for nexthops from routes and call it

Note that IPv6 (unlike IPv4) does not share the same nexthop group
between different routes, whereas mlxsw does. Therefore, whenever the
offload indication within an IPv6 nexthop group changes, all the linked
routes need to be updated.

a specific Queue. As stmmac fallsback to netdev_pick_tx() on the select
Queue callback, we need to switch all selftests logic to
dev_direct_xmit() so that we can send the given SKB on a specific Queue.

pertains to the bus device on the hardware (platform)
bus in this case, not the struct device inside the network
device. This makes the pool allocation work.

In order to probe this ethernet interface from the device tree
all physical MMIO regions must be passed as resources. Begin
this rewrite by first passing the port base address as a
resource for all platforms using this driver, remap it in
the driver and avoid using any reference of the statically
mapped virtual address in the driver.

The IXP4xx driver was initializing the MDIO bus before even
probing, in the callbacks supposed to be used for setting up
the module itself, and with the side effect of trying to
register the MDIO bus as soon as this module was loaded or
compiled into the kernel whether the device was discovered
or not.
This does not work with multiplatform environments.
To get rid of this: set up the MDIO bus from the probe()
callback and remove it in the remove() callback. Rename
the probe() and remove() calls to reflect the most common
conventions.
Since there is a bit of checking for the ethernet feature
to be present in the MDIO registering function, making the
whole module not even be registered if we can't find an
MDIO bus, we need something similar: register the MDIO
bus when the corresponding ethernet is probed, and
return -EPROBE_DEFER on the other interfaces until this
happens. If no MDIO bus is present on any of the
registered interfaces we will eventually bail out.
None of the platforms I've seen has e.g. MDIO on EthB
and only uses EthC, there is always a Ethernet hardware
on the NPE (B, C) that has the MDIO bus, we just might
have to wait for it.

The ixp46x ptp driver has a somewhat unusual setup, where the ptp
driver and the ethernet driver are in different directories but
access the same registers that are defined a platform specific
header file.
Moving everything into drivers/net/ makes it look more like most
other ptp drivers and allows compile-testing this driver on
other targets.
