The GEO_TX_POWER_LIMIT command was sent although
there is no wgds table, so the fw got wrong SAR values
from the driver.
Fix this by avoiding sending the command if no wgds
tables are available.

To avoid a direct dependency with tc actions from netfilter, wrap the
redirect bits around CONFIG_NET_REDIRECT and move helpers to
include/linux/skbuff.h. Turn on this toggle from the ifb driver, the
only existing client of these bits in the tree.
This patch adds skb_set_redirected() that sets on the redirected bit
on the skbuff, it specifies if the packet was redirect from ingress
and resets the timestamp (timestamp reset was originally missing in the
netfilter bugfix).

Currently ENA only provides the PCI remove() handler, used during rmmod
for example. This is not called on shutdown/kexec path; we are potentially
creating a failure scenario on kexec:
(a) Kexec is triggered, no shutdown() / remove() handler is called for ENA;
instead pci_device_shutdown() clears the master bit of the PCI device,
stopping all DMA transactions;
(b) Kexec reboot happens and the device gets enabled again, likely having
its FW with that DMA transaction buffered; then it may trigger the (now
invalid) memory operation in the new kernel, corrupting kernel memory area.
This patch aims to prevent this, by implementing a shutdown() handler
quite similar to the remove() one - the difference being the handling
of the netdev, which is unregistered on remove(), but following the
convention observed in other drivers, it's only detached on shutdown().
This prevents an odd issue in AWS Nitro instances, in which after the 2nd
kexec the next one will fail with an initrd corruption, caused by a wild
DMA write to invalid kernel memory. The lspci output for the adapter
present in my instance is:
00:05.0 Ethernet controller [0200]: Amazon.com, Inc. Elastic Network
Adapter (ENA) [1d0f:ec20]

====================
Mellanox, mlx5 fixes 2020-03-24
This series introduces some fixes to mlx5 driver.
From Aya, Fixes to the RX error recovery flows
From Leon, Fix IB capability mask
Please pull and let me know if there is any problem.
For -stable v5.5
('net/mlx5_core: Set IB capability mask1 to fix ib_srpt connection failure')
For -stable v5.4
('net/mlx5e: Fix ICOSQ recovery flow with Striding RQ')
('net/mlx5e: Do not recover from a non-fatal syndrome')
('net/mlx5e: Fix missing reset of SW metadata in Striding RQ reset')
('net/mlx5e: Enhance ICOSQ WQE info fields')
The above patch ('net/mlx5e: Enhance ICOSQ WQE info fields')
will fail to apply cleanly on v5.4 due to a trivial contextual conflict,
but it is an important fix, do I need to do something about it or just
assume Greg will know how to handle this ?

For non-fatal syndromes like LOCAL_LENGTH_ERR, recovery shouldn't be
triggered. In these scenarios, the RQ is not actually in ERR state.
This misleads the recovery flow which assumes that the RQ is really in
error state and no more completions arrive, causing crashes on bad page
state.

In striding RQ mode, the buffers of an RX WQE are first
prepared and posted to the HW using a UMR WQEs via the ICOSQ.
We maintain the state of these in-progress WQEs in the RQ
SW struct.
In the flow of ICOSQ recovery, the corresponding RQ is not
in error state, hence:
- The buffers of the in-progress WQEs must be released
and the RQ metadata should reflect it.
- Existing RX WQEs in the RQ should not be affected.
For this, wrap the dealloc of the in-progress WQEs in
a function, and use it in the ICOSQ recovery flow
instead of mlx5e_free_rx_descs().

When resetting the RQ (moving RQ state from RST to RDY), the driver
resets the WQ's SW metadata.
In striding RQ mode, we maintain a field that reflects the actual
expected WQ head (including in progress WQEs posted to the ICOSQ).
It was mistakenly not reset together with the WQ. Fix this here.

Add number of WQEBBs (WQE's Basic Block) to WQE info struct. Set the
number of WQEBBs on WQE post, and increment the consumer counter (cc)
on completion.
In case of error completions, the cc was mistakenly not incremented,
keeping a gap between cc and pc (producer counter). This failed the
recovery flow on the ICOSQ from a CQE error which timed-out waiting for
the cc and pc to meet.

The original change fixed an issue on RTL8168b by mimicking the vendor
driver behavior to disable MSI on chip versions before RTL8168d.
This however now caused an issue on a system with RTL8168c, see [0].

The allocated ieee_ets structure goes out of scope without being freed,
leaking memory. Appropriate result codes should be returned so that
callers do not rely on invalid data passed by reference.
Also cache the ETS config retrieved from the device so that it doesn't
need to be freed. The balance of the code was clearly written with the
intent of having the results of querying the hardware cached in the
device structure. The commensurate store was evidently missed though.

There is an indexing bug in determining these ethtool priority
counters. Instead of using the queue ID to index, we need to
normalize by modulo 10 to get the index. This index is then used
to obtain the proper CoS queue counter. Rename bp->pri2cos to
bp->pri2cos_idx to make this more clear.

The hardware offloading of the NETIF_F_HW_CSUM and NETIF_F_RXCSUM
features requires the use of Transmit Status Blocks before transmit
frame data and Receive Status Blocks before receive frame data to
carry the checksum information.
Unfortunately, these status blocks are currently only enabled when
the NETIF_F_HW_CSUM feature is enabled. As a result NETIF_F_RXCSUM
will not actually be offloaded to the hardware unless both it and
NETIF_F_HW_CSUM are enabled. Fortunately, that is the default
configuration.
This commit addresses this issue by always enabling the use of
status blocks on both transmit and receive frames. Further, it
replaces the use of a dedicated flag within the driver private
data structure with direct use of the netdev features flags.

Driver reclaims descriptors in much smaller batches, even if hardware
indicates more to reclaim, during backpressure. So, fix the check to
restart the Txq during backpressure, by looking at how many
descriptors hardware had indicated to reclaim, and not on how many
descriptors that driver had actually reclaimed. Once the Txq is
restarted, driver will reclaim even more descriptors when Tx path
is entered again.

commit 7c3bebc3d868 ("cxgb4: request the TX CIDX updates to status page")
reverted back to getting Tx CIDX updates via DMA, instead of interrupts,
introduced by commit d429005fdf2c ("cxgb4/cxgb4vf: Add support for SGE
doorbell queue timer")
However, it missed reverting back several code changes where Tx CIDX
updates are not explicitly requested during backpressure when using
interrupt mode. These missed changes cause slow recovery during
backpressure because the corresponding interrupt no longer comes and
hence results in Tx throughput drop.
So, revert back these missed code changes, as well, which will allow
explicitly requesting Tx CIDX updates when backpressure happens.
This enables the corresponding interrupt with Tx CIDX update message
to get generated and hence speed up recovery and restore back
throughput.

Andrew reported:
After a number of network port link up/down changes, sometimes the switch
port gets stuck in a state where it thinks it is still transmitting packets
but the cpu port is not actually transmitting anymore. In this state you
will see a message on the console
"mtk_soc_eth 1e100000.ethernet eth0: transmit timed out" and the Tx counter
in ifconfig will be incrementing on virtual port, but not incrementing on
cpu port.
The issue is that MAC TX/RX status has no impact on the link status or
queue manager of the switch. So the queue manager just queues up packets
of a disabled port and sends out pause frames when the queue is full.
Change the LINK bit to reflect the link status.

During initialization the driver issues a software reset command and
then waits for the system status to change back to "ready" state.
However, before issuing the reset command the driver does not check that
the system is actually in "ready" state. On Spectrum-{1,2} systems this
was always the case as the hardware initialization time is very short.
On Spectrum-3 systems this is no longer the case. This results in the
software reset command timing-out and the driver failing to load:
[ 6.347591] mlxsw_spectrum3 0000:06:00.0: Cmd exec timed-out (opcode=40(ACCESS_REG),opcode_mod=0,in_mod=0)
[ 6.358382] mlxsw_spectrum3 0000:06:00.0: Reg cmd access failed (reg_id=9023(mrsr),type=write)
[ 6.368028] mlxsw_spectrum3 0000:06:00.0: cannot register bus device
[ 6.375274] mlxsw_spectrum3: probe of 0000:06:00.0 failed with error -110
Fix this by waiting for the system to become ready both before issuing
the reset command and afterwards. In case of failure, print the last
system status to aid in debugging.

We precompute the static-static ECDH during configuration time, in order
to save an expensive computation later when receiving network packets.
However, not all ECDH computations yield a contributory result. Prior,
we were just not letting those peers be added to the interface. However,
this creates a strange inconsistency, since it was still possible to add
other weird points, like a valid public key plus a low-order point, and,
like points that result in zeros, a handshake would not complete. In
order to make the behavior more uniform and less surprising, simply
allow all peers to be added. Then, we'll error out later when doing the
crypto if there's an issue. This also adds more separation between the
crypto layer and the configuration layer.

The situation in which we wind up hitting the default case here
indicates a major bug in earlier parsing code. It is not a usual thing
that should ever happen, which means a "friendly" message for it doesn't
make sense. Rather, replace this with a WARN_ON, just like we do earlier
in the file for a similar situation, so that somebody sends us a bug
report and we can fix it.

We carry out checks to the effect of:
if (skb->protocol != wg_examine_packet_protocol(skb))
goto err;
By having wg_skb_examine_untrusted_ip_hdr return 0 on failure, this
means that the check above still passes in the case where skb->protocol
is zero, which is possible to hit with AF_PACKET:
struct sockaddr_pkt saddr = { .spkt_device = "wg0" };
unsigned char buffer[5] = { 0 };
sendto(socket(AF_PACKET, SOCK_PACKET, /* skb->protocol = */ 0),
buffer, sizeof(buffer), 0, (const struct sockaddr *)&saddr, sizeof(saddr));
Additional checks mean that this isn't actually a problem in the code
base, but I could imagine it becoming a problem later if the function is
used more liberally.
I would prefer to fix this by having wg_examine_packet_protocol return a
32-bit ~0 value on failure, which will never match any value of
skb->protocol, which would simply change the generated code from a mov
to a movzx. However, sparse complains, and adding __force casts doesn't
seem like a good idea, so instead we just add a simple helper function
to check for the zero return value. Since wg_examine_packet_protocol
itself gets inlined, this winds up not adding an additional branch to
the generated code, since the 0 return value already happens in a
mergable branch.

The indentation for the returned values are weird, causing those
warnings:
./drivers/net/phy/sfp-bus.c:579: WARNING: Unexpected indentation.
./drivers/net/phy/sfp-bus.c:619: WARNING: Unexpected indentation.
Use a list and change the identation for it to be properly
parsed by the documentation toolchain.

last_keep_alive_jiffies is updated in probe and when a keep-alive
event is received. In case the driver times-out on a keep-alive event,
it has high chances of continuously timing-out on keep-alive events.
This is because when the driver recovers from the keep-alive-timeout reset
the value of last_keep_alive_jiffies is very old, and if a keep-alive
event is not received before the next timer expires, the value of
last_keep_alive_jiffies will cause another keep-alive-timeout reset
and so forth in a loop.
Solution:
Update last_keep_alive_jiffies whenever the device is restored after
reset.
