An MC-aware mode was introduced in commit 7b8195306694 ("mlxsw:
spectrum: Configure MC-aware mode on mlxsw ports"). In MC-aware mode,
BUM traffic gets a special treatment by being assigned to a separate set
of traffic classes 8..15. Pairs of TCs 0 and 8, 1 and 9, etc., are then
configured to strictly prioritize the lower-numbered ones. The intention
is to prevent BUM traffic from flooding the switch and push out all UC
traffic, which would otherwise happen, and instead give UC traffic
precedence.
However strictly prioritizing UC traffic has the effect that UC overload
pushes out all BUM traffic, such as legitimate ARP queries. These
packets are kept in queues for a while, but under sustained UC overload,
their lifetime eventually expires and these packets are dropped. That is
detrimental to network performance as well.
Therefore configure the MC TCs (8..15) with minimum shaper of 200Mbps (a
minimum permitted value) to allow a trickle of necessary control traffic
to get through.

Add QEEC.mise (minimum shaper enable) and QEEC.min_shaper_rate to enable
configuration of minimum shaper.
Increase the QEEC length to 0x20 as well: that's the length that the
register has had for a long time now, but with the configurations that
mlxsw typically exercises, the firmware tolerated 0x1C-sized packets.
With mise=true however, FW rejects packets unless they have the full
required length.

As shown by Dmitris, we need to use csum_block_add() instead of csum_add()
when adding the FCS contribution to skb csum.
Before 4.18 (more exactly commit 88078d98d1bb "net: pskb_trim_rcsum()
and CHECKSUM_COMPLETE are friends"), the whole skb csum was thrown away,
so RXFCS changes were ignored.
Then before commit d55bef5059dd ("net: fix pskb_trim_rcsum_slow() with
odd trim offset") both mlx5 and pskb_trim_rcsum_slow() bugs were canceling
each other.
Now we fixed pskb_trim_rcsum_slow() we need to fix mlx5.
Note that this patch also rewrites mlx5e_get_fcs() to :
- Use skb_header_pointer() instead of reinventing it.
- Use __get_unaligned_cpu32() to avoid possible non aligned accesses
as Dmitris pointed out.

After a failed reload, the driver is still registered to devlink, its
devlink instance is still allocated and the 'reload_fail' flag is set.
Then, in the next reload try, the driver's allocated devlink instance will
be freed without unregistering from devlink and its components (e.g,
resources). This scenario can cause a use-after-free if the user tries to
execute command via devlink user-space tool.
Fix by not freeing the devlink instance during reload (failed or not).

When the switch driver (e.g., mlxsw_spectrum) determines it needs to
flash a new firmware version it resets the ASIC after the flashing
process. The bus driver (e.g., mlxsw_pci) then registers itself again
with mlxsw_core which means (among other things) that the device
registers itself again with the hwmon subsystem again.
Since the device was registered with the hwmon subsystem using
devm_hwmon_device_register_with_groups(), then the old hwmon device
(registered before the flashing) was never unregistered and was
referencing stale data, resulting in a use-after free.
Fix by removing reliance on device managed APIs in mlxsw_hwmon_init().

mlx5e netdevice used to calculate fragment edges by a call to
mlx5_wq_cyc_get_frag_size(). This calculation did not give the correct
indication for queues smaller than a PAGE_SIZE, (broken by default on
PowerPC, where PAGE_SIZE == 64KB). Here it is replaced by the correct new
calls/API.
Since (TX/RX) Work Queues buffers are fragmented, here we introduce
changes to the API in core driver, so that it gets a stride index and
returns the index of last stride on same fragment, and an additional
wrapping function that returns the number of physically contiguous
strides that can be written contiguously to the work queue.
This obsoletes the following API functions, and their buggy
usage in EN driver:
* mlx5_wq_cyc_get_frag_size()
* mlx5_wq_cyc_ctr2fragix()
The new API improves modularity and hides the details of such
calculation for mlx5e netdevice and mlx5_ib rdma drivers.
New calculation is also more efficient, and improves performance
as follows:
Packet rate test: pktgen, UDP / IPv4, 64byte, single ring, 8K ring size.
Before: 16,477,619 pps
After: 17,085,793 pps

Added functions to query and set link FEC policy.
To get/set FEC capabilities in PPLM reg we need to query
current link speed.
'mlx5_get_fec_speed_field' queries current link speed and returns
correct field offset.
FEC Query's return value is divided into 'active FEC policy', which is
the FEC policy used by the link, and 'configured FEC policy', which
is the FEC policy requested by the user.
The two values may differ if:
1) FEC policy was configured to 'auto',
in which case the active FEC policy would be the default FEC policy
for current link speed.
2) FEC policy was changed, but no link reset is performed. In which case,
the active FEC policy would become the configured one after a link
reset.
FEC set function sets FEC policy for all link speeds and perform link
reset.
1) If current link speed doesn't support requested FEC policy,
the function fails.
2) If a different link speed doesn't support requested FEC policy,
FEC capbilities for this speed are turned off and a warning message
is printed.

In fs_counters elements from both addlist and dellist are removed by
mlx5_fc_stats_work() without any locking. This introduces race condition
when batch of new rules is created and then immediately deleted (for
example, when error occurred during flow creation). In such case some of
the rules might be in dellist, but not in addlist when mlx5_fc_stats_work()
is executed concurrently with tc, which will result rule deletion and
use-after-free on next iteration because deleted rules are still in
addlist.
Always take dellist first to guarantee that rules can only be deleted after
they were removed from addlist.

Take struct mlx5_frag_buf out of mlx5_frag_buf_ctrl, as it is not
needed to manage and control the datapath of the fragmented buffers API.
struct mlx5_frag_buf contains control info to manage the allocation
and de-allocation of the fragmented buffer.
Its fields are not relevant for datapath, so here I take them out of the
struct mlx5_frag_buf_ctrl, except for the fragments array itself.
In addition, modified mlx5_fill_fbc to initialise the frags pointers
as well. This implies that the buffer must be allocated before the
function is called.

mlx5-updates-2018-10-17
========================================================================
From Or Gerlitz <ogerlitz@mellanox.com>:
This series from Paul adds support to mlx5 e-switch tc offloading of multiple priorities and chains.
This is made of four building blocks (along with few minor driver refactors):
[1] Split FDB fast path prio to multiple namespaces
Currently the FDB name-space contains two priorities, fast path (p0) and slow path (p1).
The slow path contains the per representor SQ send-to-vport TX rule and the match-all
RX miss rule. As a pre-step to support multi-chains and priorities, we split the FDB fast path
to multiple namespaces (sub namespaces), each with multiple priorities.
[2] E-Switch chains and priorities
A chain is a group of priorities. We use the fdb parallel sub-namespaces to implement chains,
and a flow table for each priority in them.
Because these namespaces are parallel and in series to the slow path
fdb, the chains aren't connected to each other (but to the slow path),
and one must use a explicit goto action to reach a different chain.
Flow tables for the priorities are created on demand and destroyed
once not used.
[3] Add a no-append flow insertion mode, use it for TC offloads
Enhance the driver fs core, such that if a no-append flag is set by the caller,
we add a new FTE, instead of appending the actions of the inserted rule when
the same match already exists.
For encap rules, we defer the HW offloading till we have a valid neighbor. This can
result in the packet hitting a lower priority rule in the HW DP. Use the no-append API
to push these packets to the slow path FDB table, so they go to the TC kernel DP as done
before priorities where supported.
[4] Offloading tc priorities and chains for eswitch flows
Using [1], [2] and [3] above we add the support for offloading both chains
and priorities. To get to a new chain, use the tc goto action. We support
a fixed prio range 1-16, and chains 0-3.

Currently we fail when user specify a non-zero chain, this patch adds the
support for it and tc priorities. To get to a new chain, use the tc
goto action.
Currently we support a fixed prio range 1-16, and chain range 0-3.

When adding a vxlan tc rule, and a neighbour isn't available, we
don't insert any rule to hardware. Once we enable offloading flows
with multiple priorities, a packet that should have matched this rule
will continue in hardware pipeline and might match a wrong one.
This is unlike in tc software path where it will be matched and
forwarded to the vxlan device (which will cause a ARP lookup
eventually) and stop processing further tc filters.
To address that, when when a neighbour isn't available (EAGAIN from
attach_encap), or gets deleted, change the original action to be a
forward to slow path instead. Neighbour update will restore the original
action once the neighbour becomes available. This will be done atomically

When replacing a tc flower rule, flower first requests to add the
new rule (new action), then deletes the old one.
But currently when asked to add a new tc flower flow, we append the
actions (and counters to it).
This can result in a fte with two flow counters or conflicting
actions (drop and encap action) which firmware complains/errs
about and isn't achieving what the user aimed for.
Instead, insert the flow using the new no-append flag which will add a
new HW rule, the old flow and rule will be deleted later by flower

While here, move the has_flow_tag boolean indicator to be a flag too.
This patch doesn't change any functionality.

A chain is a group of priorities, so use the fdb parallel
sub namespaces to implement chains, and a flow table for each
priority in them.
Because these namespaces are parallel and in series to the slow path
fdb, the chains aren't connected to one another (but to the slow path),
and one must use a explicit goto action to reach a different chain.
Flow tables for the priorities will be created on demand and destroyed
once not used.
The Firmware has four pools of tables for sizes S/XS/M/L (4k, 64k, 1m, 4m).
We maintain ghost copies of the pools occupancy.
When a new table is to be created, we scan the pools from large to small
and find the 1st table size which can be now created. When a table is
destroyed, we update the relevant pool.
Multi chain/prio isn't enabled yet by this patch, for now all flows
will use the default chain 0, and prio 1.

Towards supporting multi-chains and priorities, split the FDB fast path
to multiple namespaces (sub namespaces), each with multiple priorities.
This patch adds a new flow steering type, FS_TYPE_PRIO_CHAINS, which is
like current FS_TYPE_PRIO, but may contain only namespaces, and those
will be in parallel to one another in terms of managing of the flow
tables connections inside them. Meaning, while searching for the next
or previous flow table to connect for a new table inside such namespace
we skip the parallel namespaces in the same level under the
FS_TYPE_PRIO_CHAINS prio we originated from.
We use this new type for splitting the fast path prio into multiple
parallel namespaces, each containing normal prios.
The prios inside them (and their tables) will be connected to one
another, but not from one parallel namespace to another, instead the
last prio in each namespace will be connected to the next prio in
the containing FDB namespace, which is the slow path prio.

Move to have clear separation on the code path to add nic vs e-switch
flows. While here we break the code that deals with adding offloaded
TC tool to few smaller stages, each on helper function.
Besides getting us simpler and readable code, these are pre-steps
for being able to have two HW flows serving one SW TC flow for some
e-switch use cases.

Currently, when a flow rule is created using the FS core layer, the caller
has to pass the entire flow counter object and not just the counter HW
handle (ID). This requires both the FS core and the caller to have
knowledge about the inner implementation of the FS layer flow counters
cache and limits the possible users.
Move to use the counter ID across the place when dealing with flows.
Doing this decoupling, now can we privatize the inner implementation
of the flow counters.

There's no real reason for the e-switch logic to manage the creation of
counters for offloaded flows. The API already has the directive for the
caller to denote they want to attach a counter to the created flow.
As such, we go and move the management of flow counters to the mlx5e
tc offload logic. This also lets us remove an inelegant interface where
the FS layer had to provide a way to retrieve a counter from a flow rule.

Set uid as part of CQ commands so that the firmware can manage the CQ
object in a secured way.
The firmware should mark this CQ with the given uid so that it can
be used later on only by objects with the same uid.
Upon DEVX flows that use this CQ (e.g. create QP command), the
pointed CQ must have the same uid as of the issuer uid command.
When a command is issued with uid=0 it means that the issuer of the
command is trusted (i.e. kernel), in that case any pointed object
can be used regardless of its uid.
