The total number of queues available on the device is divided between
multiple physical functions (PF) in the firmware and provided to the
driver when it gets function capabilities from the firmware. Thus
each PF knows how many Tx/Rx queues it has. These queues are then
doled out to different VSIs (for LAN traffic, SR-IOV VF traffic, etc.)
To track usage of these queues at the PF level, the driver uses two
bitmaps avail_txqs and avail_rxqs. At the VSI level (i.e. struct ice_vsi
instances) the driver uses two arrays txq_map and rxq_map, to track
ownership of VSIs' queues in avail_txqs and avail_rxqs respectively.
The aforementioned bitmaps and arrays should be allocated dynamically,
because the number of queues supported by a PF is only available once
function capabilities have been queried. The current static allocation
consumes way more memory than required.
This patch removes the DECLARE_BITMAP for avail_txqs and avail_rxqs
and instead uses bitmap_zalloc to allocate the bitmaps during init.
Similarly txq_map and rxq_map are now allocated in ice_vsi_alloc_arrays.
As a result ICE_MAX_TXQS and ICE_MAX_RXQS defines are no longer needed.
Also as txq_map and rxq_map are now allocated and freed, some code
reordering was required in ice_vsi_rebuild for correct functioning.

The VF driver can call VIRTCHNL_OP_[ENABLE|DISABLE]_QUEUES separately
for each queue. Add support for virtchnl_queue_select.[tx|rx]_queues
bitmap which is used to indicate which queues to enable and disable.
Add tracing of VF Tx/Rx per queue enable state to avoid enabling enabled
queues and disabling disabled queues. Add total queues enabled count and
clear ICE_VF_STATE_QS_ENA when count is zero.

Refactor the queue handling functions that are going through queue
arrays in a way that the logic done for a single queue is pulled out and
it will be called for each ring when traversing ring array. This implies
that when disabling Tx rings we won't fill up q_ids, q_teids and
q_handles arrays. Drop also 'offset' parameter; the value from vsi's
txq_map is stored in ring->reg_idx and that drops the need for mentioned
parameter. Introduce the ice_vsi_cfg_txq, ice_vsi_stop_tx_ring and
ice_vsi_ctrl_rx_ring that are the functions with pulled out logic.
There's several Tx queue meta data (q_id, q_handle, q_teid and other)
that need to be set up during Tx queue disablement, so let's as well add
a helper structure that wraps it up and a function that will be filling
it up.

The loop counter of a for-loop is a u8 however this is being compared
to an int upper bound and this can lead to an infinite loop if the
upper bound is greater than 255 since the loop counter will wrap back

ice_is_tc_ena is used to check whether a given traffic class is
enabled. Because there are only 8 traffic classes, the function took
a u8 bitmap. This causes problems because it is cast to an unsigned
long causing a static analysis warning regarding Out-of-bounds read.
Fix this by simply updating ice_is_tc_ena to take an unsigned long.
Passing a u8 to this function should implicitly convert the value.

Check num_queue_pairs to avoid access to unallocated field of
vsi->tx_rings/vsi->rx_rings. Without this validation we can set
vsi->alloc_txq/vsi->alloc_rxq to value smaller than ICE_MAX_BASE_QS_PER_VF
and send this command with num_queue_pairs greater than
vsi->alloc_txq/vsi->alloc_rxq. This lead to access to unallocated memory.
In VF vsi alloc_txq and alloc_rxq should be the same. Get minimum
because looks more readable.
Also add validation for ring_len param. It should be greater than 32 and
be multiple of 32. Incorrect value leads to hang traffic on PF.

get_registers() blindly copies the memory written to by the
usb_control_msg() call even if the underlying urb failed.
This could lead to junk register values being read by the driver, since
some indirect callers of get_registers() ignore the return values. One
example is:
ocp_read_dword() ignores the return value of generic_ocp_read(), which
calls get_registers().
So, emulate PCI "Master Abort" behavior by setting the buffer to all
0xFFs when usb_control_msg() fails.

====================
100GbE Intel Wired LAN Driver Updates 2019-08-23
This series contains updates to ice driver only.
Dave adds logic for the necessary bits to be set in the VSI context for
the PF_VSI and the TX_descriptors for control packets egressing the
PF_VSI. Updated the logic to detect both DCBx and LLDP states in the
firmware engine to account for situations where DCBx is enabled and LLDP
is disabled. Fixed the driver to treat the DCBx state of "NOT_STARTED"
as a valid state and should not assume "is_fw_lldp" true automatically.
Since "enable-fw-lldp" flag was confusing and cumbersome, change the
flag to "fw-lldp-agent" with a value of on or off to help clarify
whether the LLDP agent is running or not.
Brett fixes an issue where synchronize_irq() was being called from the
host of VF's, which should not be done.
Michal fixed an issue when rebuilding the DCBx configuration while in
IEEE mode versus CEE mode, so add a check before copying the
configuration value to ensure we are only in CEE mode.
Jake fixes the PF to reject any VF request to setup head writeback since
the support has been deprecated.
Mitch adds an additional check to ensure the VF is active before sending
out an error message that a message was unable to be sent to a
particular VF.
Chinh updates the driver to use "topology" mode when checking the PHY
for status, since this mode provides us the current module type that is
available. Fixes the driver from clearing the auto_fec_enable bit which
was blocking a user from forcing non-spec compliant FEC configurations.
Amruth does a refactor on the code to first check, then assign in the
virtual channel space.
Bruce updates the driver to actually update the stats when a user runs
the ethtool command 'ethtool -S <iface>' instead of providing a snapshot
of the stats that maybe from a second ago.
Akeem fixes up the adding/removing of VSI MAC filters for VFs, so that
VFs cannot add/remove a filter from another VSI. We now track the
number of filters added right from when the VF resources get allocated
and won't get into MAC filter mis-match issue in the switch.

IQD devices offer limited support for bulking: all frames in a TX buffer
need to have the same target. qeth_iqd_may_bulk() implements this
constraint, and allows us to defer the TX doorbell until
(a) the buffer is full (since each buffer needs its own doorbell), or
(b) the entire TX queue is full, or
(b) we reached the BQL limit.

Due to their large MTU and potentially low utilization of TX buffers,
IQD devices in particular require fast TX recycling. This makes them
a prime candidate for a TX NAPI path in qeth.
qeth_tx_poll() uses the recently introduced qdio_inspect_queue() helper
to poll the TX queue for completed buffers. To avoid hogging the CPU for
too long, we yield to the stack after completing an entire queue's worth
of buffers.
While IQD is expected to transfer its buffers synchronously (and thus
doesn't support TX interrupts), a timer covers for the odd case where a
TX buffer doesn't complete synchronously. Currently this timer should
only ever fire for
(1) the mcast queue,
(2) the occasional race, where the NAPI poll code observes an update to
queue->used_buffers while the TX doorbell hasn't been issued yet.

This consolidates the SW statistics code, and improves it to
(1) account for the header overhead of each segment on a TSO skb,
(2) count dangling packets as in-error (during eg. shutdown), and
(3) only count offloads when the skb was successfully transmitted.
We also count each segment of an TSO skb as one packet - except for
tx_dropped, to be consistent with dev->tx_dropped.

If a driver wants to use the new Output Queue poll code, then the qdio
layer must disable its internal Queue scanning. Let the driver select
this mode by passing a special scan_threshold of 0.
As the scan_threshold is the same for all Output Queues, also move it
into the main qdio_irq struct. This allows for fast opt-out checking, a
driver is expected to operate either _all_ or none of its Output Queues
in polling mode.

While commit d36deae75011 ("qdio: extend API to allow polling") enhanced
the qdio layer so that drivers can poll their Input Queues, we don't
have the corresponding infrastructure for Output Queues yet.
Factor out a helper that scans a single QDIO Queue, so that qeth can
implement TX NAPI on top of it.
While doing so, remove the duplicated tracking of the next-to-scan index
(q->first_to_check vs q->first_to_kick) in this code path.
qdio_handle_aobs() needs to move slightly upwards in the code hierarchy,

Commit d4c08afafa04 ("s390/qeth: streamline SNMP cmd code") removed
the bounds checking for req_len, under the assumption that the check in
qeth_alloc_cmd() would suffice.
But that code path isn't sufficiently robust to handle a user-provided
data_length, which could overflow (when adding the cmd header overhead)
before being checked against QETH_BUFSIZE. We end up allocating just a
tiny iob, and the subsequent copy_from_user() writes past the end of
that iob.
Special-case this path and add a coarse bounds check, to protect against
maliciuous requests. This let's the subsequent code flow do its normal
job and precise checking, without risk of overflow.

Pull rdma fixes from Doug Ledford:
"No beating around the bush: this is a monster pull request for an -rc5
kernel. Intel hit me with a series of fixes for TID processing.
Mellanox hit me with a series for their UMR memory support.
And we had one fix for siw that fixes the 32bit build warnings and
because of the number of casts that had to be changed to properly
silence the warnings, that one patch alone is a full 40% of the LOC of
this entire pull request. Given that this is the initial release
kernel for siw, I'm trying to fix anything in it that we can, so that
adds to the impetus to take fixes for it like this one.
I had to do a rebase early in the week. Jason had thought he put a
patch on the rc queue that he needed to be there so he could base some
work off of it, and it had actually not been placed there. So he asked
me (on Tuesday) to fix that up before pushing my wip branch to the
official rc branch. I did, and that's why the early patches look like
they were all committed at the same time on Tuesday. That bunch had
been in my queue prior.
The various patches all pass my test for being legitimate fixes and
not attempts to slide new features or development into a late rc.
Well, they were all fixes with the exception of a couple clean up
patches people wrote for making the fixes they also wrote better (like
a cleanup patch to move UMR checking into a function so that the
remaining UMR fix patches can reference that function), so I left
those in place too.
My apologies for the LOC count and the number of patches here, it's
just how the cards fell this cycle.
Summary:
- Fix siw buffer mapping issue
- Fix siw 32/64 casting issues
- Fix a KASAN access issue in bnxt_re
- Fix several memory leaks (hfi1, mlx4)
- Fix a NULL deref in cma_cleanup
- Fixes for UMR memory support in mlx5 (4 patch series)
- Fix namespace check for restrack
- Fixes for counter support
- Fixes for hfi1 TID processing (5 patch series)
- Fix potential NULL deref in siw
- Fix memory page calculations in mlx5"

Return code value could be non deterministic in case of wrong size read.
With this patch, if such error occurs, set rc to be -EIO.
In addition, mlx5_hv_config_common() supports reading of
HV_CONFIG_BLOCK_SIZE_MAX bytes only, fix to early return error with
bad input.
