The stmmac has the possibility to automatically strip the padding/FCS for IEEE
802.3 type frames. This feature is enabled conditionally. Therefore, the stmmac
receive path has to have a determination logic whether the FCS has to be
stripped in software or not.
In fact, for DSA this ACS feature is disabled and the determination logic
doesn't check for it properly. For instance, when using DSA in combination with
an older stmmac (pre version 4), the FCS is not stripped by hardware or software
which is problematic.
So either add another check for DSA to the fast path or simply disable ACS
feature completely. The latter approach has been chosen, because most of the
time the FCS is stripped in software anyway and it removes conditionals from the
receive fast path.

Introduce MACsec skb_metadata_dst and mlx5 macsec offload
v1->v2:
- attach mlx5 implementation patches.
This patchset introduces MACsec skb_metadata_dst to lay the ground
for MACsec HW offload.
MACsec is an IEEE standard (IEEE 802.1AE) for MAC security.
It defines a way to establish a protocol independent connection
between two hosts with data confidentiality, authenticity and/or
integrity, using GCM-AES. MACsec operates on the Ethernet layer and
as such is a layer 2 protocol, which means it’s designed to secure
traffic within a layer 2 network, including DHCP or ARP requests.
Linux has a software implementation of the MACsec standard and
HW offloading support.
The offloading is re-using the logic, netlink API and data
structures of the existing MACsec software implementation.
For Tx:
In the current MACsec offload implementation, MACsec interfaces shares
the same MAC address by default.
Therefore, HW can't distinguish from which MACsec interface the traffic
originated from.
MACsec stack will use skb_metadata_dst to store the SCI value, which is
unique per MACsec interface, skb_metadat_dst will be used later by the
offloading device driver to associate the SKB with the corresponding
offloaded interface (SCI) to facilitate HW MACsec offload.
For Rx:
Like in the Tx changes, if there are more than one MACsec device with
the same MAC address as in the packet's destination MAC, the packet will
be forward only to one of the devices and not neccessarly to the desired one.
Offloading device driver sets the MACsec skb_metadata_dst sci
field with the appropriaate Rx SCI for each SKB so the MACsec rx handler
will know to which port to divert those skbs, instead of wrongly solely
relaying on dst MAC address comparison.
1) patch 1,2, Add support to skb_metadata_dst in MACsec code:
net/macsec: Add MACsec skb_metadata_dst Tx Data path support
net/macsec: Add MACsec skb_metadata_dst Rx Data path support
2) patch 3, Move some MACsec driver code for sharing with various
drivers that implements offload:
net/macsec: Move some code for sharing with various drivers that
implements offload
3) The rest of the patches introduce mlx5 implementation for macsec
offloads TX and RX via steering tables.
a) TX, intercept skbs with macsec offlad mark in skb_metadata_dst and mark
the descriptor for offload.
b) RX, intercept offloaded frames and prepare the proper
skb_metadata_dst to mark offloaded rx frames.

MACsec driver need to distinguish to which offload device the MACsec
is target to, in order to handle them correctly.
This can be done by attaching a metadata_dst to a SKB with a SCI,
when there is a match on MACsec rule.
To achieve that, there is a map between fs_id to SCI, so for each RX SC,
there is a unique fs_id allocated when creating RX SC.
fs_id passed to device driver as metadata for packets that passed Rx
MACsec offload to aid the driver to retrieve the matching SCI.

Rx flow steering consists of two flow tables (FTs).
The first FT (crypto table) have one default miss rule so non MACsec
offloaded packets bypass the MACSec tables.
All others flow table entries (FTEs) are divided to two equal groups
size, both of them are for MACsec packets:
The first group is for MACsec packets which contains SCI field in the
SecTAG header.
The second group is for MACsec packets which doesn't contain SCI,
where need to match on the source MAC address (only if the SCI
is built from default MACsec port).
Destination MAC address, ethertype and some of SecTAG fields
are also matched for both groups.
In case of match, invoke decrypt action on the packet.
For each MACsec Rx offloaded SA two rules are created: one with SCI
and one without SCI.
The second FT (check table) has two fixed rules:
One rule is for verifying that the previous offload actions were
finished successfully.
In this case, need to decap the SecTAG header and forward the packet
for further processing.
Another default rule for dropping packets that failed in the previous
decrypt actions.
The MACsec FTs are created on demand when the first MACsec rule is
added and destroyed when the last MACsec rule is deleted.

MACsec driver marks Tx packets for device offload using a dedicated
skb_metadata_dst which holds a 64 bits SCI number.
A previously set rule will match on this number so the correct SA is used
for the MACsec operation.
As device driver can only provide 32 bits of metadata to flow tables,
need to used a mapping from 64 bit to 32 bits marker or id,
which is can be achieved by provide a 32 bit unique flow id in the
control path, and used a hash table to map 64 bit to the unique id in the
datapath.

Tx flow steering consists of two flow tables (FTs).
The first FT (crypto table) has two fixed rules:
One default miss rule so non MACsec offloaded packets bypass the MACSec
tables, another rule to make sure that MACsec key exchange (MKE) traffic
passes unencrypted as expected (matched of ethertype).
On each new MACsec offload flow, a new MACsec rule is added.
This rule is matched on metadata_reg_a (which contains the id of the
flow) and invokes the MACsec offload action on match.
The second FT (check table) has two fixed rules:
One rule for verifying that the previous offload actions were
finished successfully and packet need to be transmitted.
Another default rule for dropping packets that were failed in the
offload actions.

Most recent cards (8000 series and newer) had enough hardware support

v3: fixed bug caused by usage of htons in PTP_EVENT_PORT definition.
It was used in more places, where htons was used too, so using it

tests because it only affected if timestamping through the MC, but
the model I used do it through the MAC. Detected by kernel test

Add initial BYTE_ORDER read to sync the 32-bit accesses over the 16-bit
mdio bus to improve driver robustness.
The lan9303 expects two mdio read transactions back-to-back to read a
32-bit register. The first read transaction causes the other half of the
32-bit register to get latched. The subsequent read returns the latched
second half of the 32-bit read. The BYTE_ORDER register is an exception to
this rule. As it is a constant value, there is no need to latch the second
half. We read this register first in case there were reads during the boot
loader process that might have occurred prior to this driver taking over
ownership of accessing this device.
This patch has been tested on the SAMA5D3-EDS with a LAN9303 RMII daughter

The KSZ9896 is similar to KSZ9897 but has only one configurable
MII/RMII/RGMII/GMII cpu port.

pull-request: bpf-next 2022-09-05
The following pull-request contains BPF updates for your *net-next* tree.
We've added 106 non-merge commits during the last 18 day(s) which contain
a total of 159 files changed, 5225 insertions(+), 1358 deletions(-).
There are two small merge conflicts, resolve them as follows:
1) tools/testing/selftests/bpf/DENYLIST.s390x
Commit 27e23836ce22 ("selftests/bpf: Add lru_bug to s390x deny list") in
bpf tree was needed to get BPF CI green on s390x, but it conflicted with
newly added tests on bpf-next. Resolve by adding both hunks, result:
[...]
lru_bug # prog 'printk': failed to auto-attach: -524
setget_sockopt # attach unexpected error: -524 (trampoline)
cb_refs # expected error message unexpected error: -524 (trampoline)
cgroup_hierarchical_stats # JIT does not support calling kernel function (kfunc)
htab_update # failed to attach: ERROR: strerror_r(-524)=22 (trampoline)
[...]
2) net/core/filter.c
Commit 1227c1771dd2 ("net: Fix data-races around sysctl_[rw]mem_(max|default).")
from net tree conflicts with commit 29003875bd5b ("bpf: Change bpf_setsockopt(SOL_SOCKET)
to reuse sk_setsockopt()") from bpf-next tree. Take the code as it is from
bpf-next tree, result:
[...]
if (getopt) {
if (optname == SO_BINDTODEVICE)
return -EINVAL;
return sk_getsockopt(sk, SOL_SOCKET, optname,
KERNEL_SOCKPTR(optval),
KERNEL_SOCKPTR(optlen));
}
return sk_setsockopt(sk, SOL_SOCKET, optname,
KERNEL_SOCKPTR(optval), *optlen);
[...]
The main changes are:
1) Add any-context BPF specific memory allocator which is useful in particular for BPF
tracing with bonus of performance equal to full prealloc, from Alexei Starovoitov.
2) Big batch to remove duplicated code from bpf_{get,set}sockopt() helpers as an effort
to reuse the existing core socket code as much as possible, from Martin KaFai Lau.
3) Extend BPF flow dissector for BPF programs to just augment the in-kernel dissector
with custom logic. In other words, allow for partial replacement, from Shmulik Ladkani.
4) Add a new cgroup iterator to BPF with different traversal options, from Hao Luo.
5) Support for BPF to collect hierarchical cgroup statistics efficiently through BPF
integration with the rstat framework, from Yosry Ahmed.
6) Support bpf_{g,s}et_retval() under more BPF cgroup hooks, from Stanislav Fomichev.
7) BPF hash table and local storages fixes under fully preemptible kernel, from Hou Tao.
8) Add various improvements to BPF selftests and libbpf for compilation with gcc BPF
backend, from James Hilliard.
9) Fix verifier helper permissions and reference state management for synchronous
callbacks, from Kumar Kartikeya Dwivedi.
10) Add support for BPF selftest's xskxceiver to also be used against real devices that
support MAC loopback, from Maciej Fijalkowski.
11) Various fixes to the bpf-helpers(7) man page generation script, from Quentin Monnet.
12) Document BPF verifier's tnum_in(tnum_range(), ...) gotchas, from Shung-Hsi Yu.
13) Various minor misc improvements all over the place.

During stress tests with adding VF to namespace and changing vf's
trust there was a race between iavf_reset_task and iavf_close.
Sometimes when IAVF_FLAG_AQ_DISABLE_QUEUES from iavf_close was sent
to PF after reset and before IAVF_AQ_GET_CONFIG was sent then PF
returns error IAVF_NOT_SUPPORTED to disable queues request and
following requests. There is need to get_config before other
aq_required will be send but iavf_close clears all flags, if
get_config was not sent before iavf_close, then it will not be send
at all.
In case when IAVF_FLAG_AQ_GET_OFFLOAD_VLAN_V2_CAPS was sent before
IAVF_FLAG_AQ_DISABLE_QUEUES then there was rtnl_lock deadlock
between iavf_close and iavf_adminq_task until iavf_close timeouts
and disable queues was sent after iavf_close ends.
There was also a problem with sending delete/add filters.
Sometimes when filters was not yet added to PF and in
iavf_close all filters was set to remove there might be a try
to remove nonexistent filters on PF.
Add aq_required_tmp to save aq_required flags and send them after
disable_queues will be handled. Clear flags given to iavf_down
different than IAVF_FLAG_AQ_GET_CONFIG as this flag is necessary
to sent other aq_required. Remove some flags that we don't
want to send as we are in iavf_close and we want to disable
interface. Remove filters which was not yet sent and send del
filters flags only when there are filters to remove.

'buf' is locale to the ice_sched_init_port() function.
There is no point in using devm_kzalloc()/devm_kfree().
use kzalloc()/kfree() instead.

Several functions in ice_common.c check the firmware API version to see if
the current API version meets some minimum requirement.
Improve the readability of these checks by introducing
ice_is_fw_api_min_ver, a helper function to perform that check.
