netif_queue_set_napi asserts whether RTNL lock is held if
the netdev is initialized.
Acquire the RTNL lock before activating or deactivating
RQs/SQs if the lock has not been held before in the flow.

coalescing
Channels can potentially have independent mdev instances. Do not refer to
the global mdev instance in the mlx5e_priv instance for channel FW
operations related to coalescing. CQ numbers that would be valid on the
channel's mdev instance may not be correctly referenced if using the
mlx5e_priv instance.

The cited patch introduces the concept of buckets in LAG in hash mode.
However, the patch doesn't clear the number of buckets in the LAG
deactivation. This results in using the wrong number of buckets in
case user create a hash mode LAG and afterwards create a non-hash
mode LAG.
Hence, restore buckets number to default after hash mode LAG
deactivation.

I noticed that only 3 out of the 4 input bits were used,
mt.key->flags & FLOW_DIS_IS_FRAGMENT was never checked.
In order to avoid a complicated maze, I converted it to
use a 16 byte mapping table.
As shown in the table below the old heuristics doesn't
always do the right thing, ie. when FLOW_DIS_IS_FRAGMENT=1/1
then it used to only match follow-up fragment packets.
Here are all the combinations, and their resulting new/old
VCAP key/mask filter:
/- FLOW_DIS_IS_FRAGMENT (key/mask)
| /- FLOW_DIS_FIRST_FRAG (key/mask)
| | /-- new VCAP fragment (key/mask)
v v v v- old VCAP fragment (key/mask)
0/0 0/0 -/- -/- impossible (due to entry cond. on mask)
0/0 0/1 -/- 0/3 !! invalid (can't match non-fragment + follow-up frag)
0/0 1/0 -/- -/- impossible (key > mask)
0/0 1/1 1/3 1/3 first fragment
0/1 0/0 0/3 3/3 !! not fragmented
0/1 0/1 0/3 3/3 !! not fragmented (+ not first fragment)
0/1 1/0 -/- -/- impossible (key > mask)
0/1 1/1 -/- 1/3 !! invalid (non-fragment and first frag)
1/0 0/0 -/- -/- impossible (key > mask)
1/0 0/1 -/- -/- impossible (key > mask)
1/0 1/0 -/- -/- impossible (key > mask)
1/0 1/1 -/- -/- impossible (key > mask)
1/1 0/0 1/1 3/3 !! some fragment
1/1 0/1 3/3 3/3 follow-up fragment
1/1 1/0 -/- -/- impossible (key > mask)
1/1 1/1 1/3 1/3 first fragment
In the datasheet the VCAP fragment values are documented as:
0 = no fragment
1 = initial fragment
2 = suspicious fragment
3 = valid follow-up fragment
Result: 3 combinations match the old behavior,
3 combinations have been corrected,
2 combinations are now invalid, and fail,
8 combinations are impossible.
It should now be aligned with how FLOW_DIS_IS_FRAGMENT
and FLOW_DIS_FIRST_FRAG is set in __skb_flow_dissect() in
net/core/flow_dissector.c
Since the VCAP fragment values are not a bitfield, we have
to ignore the suspicious fragment value, eg. when matching
on any kind of fragment with FLOW_DIS_IS_FRAGMENT=1/1.
Only compile tested, and logic tested in userspace, as I
unfortunately don't have access to this switch chip (yet).

Currently, we can read OOB data without MSG_OOB by using MSG_PEEK
when OOB data is sitting on the front row, which is apparently
wrong.
>>> from socket import *
>>> c1, c2 = socketpair(AF_UNIX, SOCK_STREAM)
>>> c1.send(b'a', MSG_OOB)
1
>>> c2.recv(1, MSG_PEEK | MSG_DONTWAIT)
b'a'
If manage_oob() is called when no data has been copied, we only
check if the socket enables SO_OOBINLINE or MSG_PEEK is not used.
Otherwise, the skb is returned as is.
However, here we should return NULL if MSG_PEEK is set and no data
has been copied.
Also, in such a case, we should not jump to the redo label because
we will be caught in the loop and hog the CPU until normal data
comes in.
Then, we need to handle skb == NULL case with the if-clause below
the manage_oob() block.
With this patch:
>>> from socket import *
>>> c1, c2 = socketpair(AF_UNIX, SOCK_STREAM)
>>> c1.send(b'a', MSG_OOB)
1
>>> c2.recv(1, MSG_PEEK | MSG_DONTWAIT)

When we call recv() for AF_UNIX socket, we first peek one skb and
calls manage_oob() to check if the skb is sent with MSG_OOB.
However, when we fetch the next (and the following) skb, manage_oob()
is not called now, leading a wrong behaviour.
Let's say a socket send()s "hello" with MSG_OOB and the peer tries
to recv() 5 bytes with MSG_PEEK. Here, we should get only "hell"
without 'o', but actually not:
>>> from socket import *
>>> c1, c2 = socketpair(AF_UNIX, SOCK_STREAM)
>>> c1.send(b'hello', MSG_OOB)
5
>>> c2.recv(5, MSG_PEEK)
b'hello'
The first skb fills 4 bytes, and the next skb is peeked but not
properly checked by manage_oob().
Let's move up the again label to call manage_oob() for evry skb.
With this patch:
>>> from socket import *
>>> c1, c2 = socketpair(AF_UNIX, SOCK_STREAM)
>>> c1.send(b'hello', MSG_OOB)
5
>>> c2.recv(5, MSG_PEEK)

====================
Support some features for the HNS3 ethernet driver
Currently, the hns3 driver does not have the trace
of the command queue. As a result, it is difficult to
locate the communication between the driver and firmware.
Therefore, the trace function of the command queue is
added in this patch set to facilitate the locating of
communication problems between the driver and firmware.
If a RAS occurs, the driver will automatically reset to attempt
to recover the RAS. Therefore, to locate the cause of the RAS,
it is necessary to save the values of some RAS-related registers
before the reset. So we added a patch in this patch set to
print these information.

Revert "NFC: fix attrs checks in netlink interface"
This reverts commit 18917d51472fe3b126a3a8f756c6b18085eb8130.
Our checks found weird attrs present check in function
nfc_genl_dep_link_down() and nfc_genl_llc_get_params(), which are
introduced by commit 18917d51472f ("NFC: fix attrs checks in netlink
interface").
According to its message, it should add checks for functions
nfc_genl_deactivate_target() and nfc_genl_fw_download(). However, it
didn't do that. In fact, the expected checks are added by
(1) commit 385097a36757 ("nfc: Ensure presence of required attributes in
the deactivate_target handler") and
(2) commit 280e3ebdafb8 ("nfc: Ensure presence of NFC_ATTR_FIRMWARE_NAME
attribute in nfc_genl_fw_download()"). Perhaps something went wrong.
Anyway, the attr NFC_ATTR_TARGET_INDEX is never accessed in callback
nfc_genl_dep_link_down() and same for NFC_ATTR_FIRMWARE_NAME and
nfc_genl_llc_get_params(). Thus, remove those checks.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove

selftests: move netfilter tests to net
First patch in this series moves selftests/netfilter/
to selftests/net/netfilter/.
Passing this via net-next rather than nf-next for this reason.
Main motivation is that a lot of these scripts only work on my old
development VM, I hope that placing this in net/ will get these
tests to get run in more regular intervals (and tests get more robust).
Changes are:
- make use of existing 'setup_ns' and 'busywait' helpers
- fix shellcheck warnings
- add more SKIP checks to avoid failures
- get rid of netcat in favor of socat, too many test
failures due to 'wrong' netcat flavor
- do not assume rp_filter sysctl is off
I have more patches that fix up the remaining test scripts,
but the series was too large to send them at once (34 patches).
After all scripts are fixed up, tests pass on both my Debian
and Fedora test machines.
MAINTAINERS is updated to reflect that future updates should be handled
via netfilter-devel@.

While at it, address warnings generated by shellcheck and fix following
minor issues:
- some distros place netem in 'extra' modules package, so add a skip check for netem-attach
failure.
- tc prints a warning for the 100mbit class:
"Warning: sch_htb: quantum of class 10001 is big. Consider r2q change."
Silence this by increasing the divisor.

Also, fix two issues reported by Pablo Neira:

else sysctl cannot be set.
2. ping for netns4 fails if rp_filter is enabled in bridge netns,

Doing so gets us dynamically generated netns names.
Also:
* do not assume rp_filter is disabled, if its on script failed
* reduce timeout (-W) for "expected to fail" ping commands
* don't print PASS line for basic sanity ping
* shellcheck cleanups

.. so this can start re-using existing lib.sh infra in next patches.
Several of these scripts will not work, e.g. because they assume
rp_filter is disabled, or reliance on a particular version/flavor
of "netcat" tool.
Add config settings for them.
nft_trans_stress.sh script is removed, it also exists in the nftables
userspace selftests. I do not see a reason to keep two versions in
different repositories/projects.
The settings file is removed for now:
It was used to increase the timeout to avoid slow scripts from getting
zapped by the 45s timeout, but some of the slow scripts can be sped up.
Re-add it later for scripts that cannot be sped up easily.
Update MAINTAINERS to reflect that future updates to netfilter
scripts should go through netfilter-devel@.

Commit 0c76106cb975 ("scsi: sd: Fix TCG OPAL unlock on system resume")
incorrectly handles failures of scsi_resume_device() in
ata_scsi_dev_rescan(), leading to a double call to
spin_unlock_irqrestore() to unlock a device port. Fix this by redefining
the goto labels used in case of errors and only unlock the port
scsi_scan_mutex when scsi_resume_device() fails.
Bug found with the Smatch static checker warning:
drivers/ata/libata-scsi.c:4774 ata_scsi_dev_rescan()
error: double unlocked 'ap->lock' (orig line 4757)

The ice physical function driver needs to configure the association of
queues and interrupts on behalf of its virtual functions. This is done over
virtchnl by the VF sending messages during its initialization phase. These
messages contain a vector_id which the VF wants to associate with a given
queue. This ID is relative to the VF space, where 0 indicates the control
IRQ for non-queue interrupts.
When programming the mapping, the PF driver currently passes this vector_id
directly to the low level functions for programming. This works for SR-IOV,
because the hardware uses the VF-based indexing for interrupts.
This won't work for Scalable IOV, which uses PF-based indexing for
programming its VSIs. To handle this, the driver needs to be able to look
up the proper index to use for programming. For typical IRQs, this would be
the q_vector->reg_idx field.
The q_vector->reg_idx can't be set to a VF relative value, because it is
used when the PF needs to control the interrupt, such as when triggering a
software interrupt on stopping the Tx queue. Thus, introduce a new
q_vector->vf_reg_idx which can store the VF relative index for registers
which expect this.
Use this in ice_cfg_interrupt to look up the VF index from the q_vector.
This allows removing the vector ID parameter of ice_cfg_interrupt. Also
notice that this function returns an int, but then is cast to the virtchnl
error enumeration, virtchnl_status_code. Update the return type to indicate
it does not return an integer error code. We can't use normal error codes
here because the return values are passed across the virtchnl interface.
This will allow the future Scalable IOV VFs to correctly look up the index
needed for programming the VF queues without breaking SR-IOV.

Commit fe1c5ca2fe76 ("ice: implement num_msix field per VF") updated the
driver to allow for per-VF MSI-X configuration. The initial defaults were
set in ice_create_vf_entries(). This logic is better placed in
ice_initialize_vf_entry(). Indeed, that function already sets
vf->num_vf_qs, as well as initializes the allow list via calling
ice_vc_set_default_allowlist().
Move this logic into ice_initialize_vf_entry(). This makes the code clear,
and ensures that these VF fields will be initialized properly for both
SR-IOV VFs and the upcoming Scalable IOV VFs.

Add support for 'flow-type ether' Flow Director rules via ethtool.
Create packet segment info for filter configuration based on ethtool
command parameters. Reuse infrastructure already created for
ipv4 and ipv6 flows to convert packet segment into
extraction sequence, which is later used to program the filter
inside Flow Director block of the Rx pipeline.
Rules not containing masks are processed by the Flow Director,
and support the following set of input parameters in all combinations:
src, dst, proto, vlan-etype, vlan, action.
It is possible to specify address mask in ethtool parameters but only
00:00:00:00:00 and FF:FF:FF:FF:FF are valid.
The same applies to proto, vlan-etype and vlan masks:
only 0x0000 and 0xffff masks are valid.
Testing:
(DUT) iperf3 -s
(DUT) ethtool -U ens785f0np0 flow-type ether dst <ens785f0np0 mac> \
action 10
(DUT) watch 'ethtool -S ens785f0np0 | grep rx_queue'
(LP) iperf3 -c ${DUT_IP}
Counters increase only for:
'rx_queue_10_packets'
'rx_queue_10_bytes'
