To offload the encap rule when the tunnel IP is configured on an
openvswitch internal port, driver need to overwrite vport metadata in
reg_c0 to the value assigned to the internal port, then forward
packets to root table to be processed again by the rules matching on
the metadata for such internal port.
When such rule is combined with header rewrite and mirror, openvswitch
generates the rule like the following, because it resets mirror after
packets are modified.
in_port(enp8s0f0npf0sf1),..,
actions:enp8s0f0npf0sf2,set(tunnel(...)),set(ipv4(...)),vxlan_sys_4789,enp8s0f0npf0sf2
The split_count was introduced before to support rewrite and mirror.
Driver splits the rule into two different hardware rules in order to
offload it. But it's not enough to offload the above complicated rule
because of the limitations, in both driver and firmware.
To resolve this issue, the destination array is split again after the
destination indexed by split_count. An extra rule is added for the
leftover destinations (in the above example, it is enp8s0f0npf0sf2),
and is inserted to post_act table. And the extra destination is added
in the original rule to forward to post_act table, so the extra mirror
is done there.

In the commit a2a73ea14b1a ("net/mlx5e: Don't listen to remove flows
event"), remove_flow_enable event is removed, and the hard limit
usually relies on software mechanism added in commit b2f7b01d36a9
("net/mlx5e: Simulate missing IPsec TX limits hardware
functionality"). But the delayed work is rescheduled every one second,
which is slow for fast traffic. As a result, traffic can't be blocked
even reaches the hard limit, which usually happens when soft and hard
limits are very close.
In reality it won't happen because soft limit is much lower than hard
limit. But, as an optimization for RX to block traffic when reaching
hard limit, need to set remove_flow_enable. When remove flow is
enabled, IPSEC HARD_LIFETIME ASO syndrome will be set in the metadata
defined in the ASO return register if packets reach hard lifetime
threshold. And those packets are dropped immediately by the steering
table.

Currently MLX5E_TC_MAX_INT_PORT_NUM is 8. Usually int port has one
ingress and one egress rules. But sometimes, a temporary rule can be
offloaded as well, eg:
recirc_id(0),in_port(br-phy),eth(src=10:70:fd:87:57:c0,dst=33:33:00:00:00:16),
eth_type(0x86dd),ipv6(frag=no), packets:2, bytes:180, used:0.060s,
actions:enp8s0f0
If one int port device offloads 3 rules, only 2 devices can offload.
Other devices will hit the limit and fail to offload. Actually it is
insufficient for customers. So increase the number to 32.

f1294617d2f38bd2b9f6cce516b0326858b61182 removed the custom function for
ndo_eth_ioctl and used the standard phy_do_ioctl which calls
phy_mii_ioctl. However since then, this driver was ported to phylink
where it makes more sense to call phylink_mii_ioctl.
Bring back custom function that calls phylink_mii_ioctl.

During initialization with the vnic server, a bitstring is communicated
to the client regarding header info needed during CSO (See "VNIC
Capabilities" in PAPR). Most of the time, to be safe, vnic server
requests header info for CSO. When header info is needed, multiple TX
descriptors are required per skb; This limits the driver to use
send_subcrq_indirect instead of send_subcrq_direct.
Previously, the vnic server request for header info was ignored. This
allowed the use of send_sub_crq_direct. Transmissions were successful
because the bitstring returned by vnic server is broad and over
cautionary. It was observed that mlx backing devices could actually
transmit and handle CSO packets without the vnic server receiving
header info (despite the fact that the bitstring requested it).
There was a trust issue: The bitstring was overcautionary. This extra
precaution (requesting header info when the backing device may not use
it) comes at the cost of performance (using direct vs indirect hcalls
has a 30% delta in small packet RR transaction rate). So it has been
requested that the vnic server team tries to ensure that the bitstring
is more exact. In the meantime, disable CSO when it is possible to use
the skb in the send_subcrq_direct path. In other words, calculate the
checksum before handing the packet to FW when the packet is not
segmented and xmit_more is false.
Since the code path is only possible if the skb is non GSO and xmit_more
is false, the cost of doing checksum in the send_subcrq_direct path is
minimal. Any large segmented skb will have xmit_more set to true more
frequently and it is inexpensive to do checksumming on a small skb.
The worst-case workload would be a 9000 MTU TCP_RR test with close
to MTU sized packets (and TSO off). This allows xmit_more to be false
more frequently and open the code path up to use send_subcrq_direct.
Observing trace data (graph-time = 1) and packet rate with this workload
shows minimal performance degradation:
1. NIC does checksum w headers, safely use send_subcrq_indirect:
- Packet rate: 631k txs
- Trace data:
ibmvnic_xmit = 44344685.87 us / 6234576 hits = AVG 7.11 us
skb_checksum_help = 4.07 us / 2 hits = AVG 2.04 us
^ Notice hits, tracing this just for reassurance
ibmvnic_tx_scrq_flush = 33040649.69 us / 5638441 hits = AVG 5.86 us
send_subcrq_indirect = 37438922.24 us / 6030859 hits = AVG 6.21 us
2. NIC does checksum w/o headers, dangerously use send_subcrq_direct:
- Packet rate: 831k txs
- Trace data:
ibmvnic_xmit = 48940092.29 us / 8187630 hits = AVG 5.98 us
skb_checksum_help = 2.03 us / 1 hits = AVG 2.03
ibmvnic_tx_scrq_flush = 31141879.57 us / 7948960 hits = AVG 3.92 us
send_subcrq_indirect = 8412506.03 us / 728781 hits = AVG 11.54
^ notice hits is much lower b/c send_subcrq_direct was called
^ wasn't traceable
3. driver does checksum, safely use send_subcrq_direct (THIS PATCH):
- Packet rate: 829k txs
- Trace data:
ibmvnic_xmit = 56696077.63 us / 8066168 hits = AVG 7.03 us
skb_checksum_help = 8587456.16 us / 7526072 hits = AVG 1.14 us
ibmvnic_tx_scrq_flush = 30219545.55 us / 7782409 hits = AVG 3.88 us
send_subcrq_indirect = 8638326.44 us / 763693 hits = AVG 11.31 us
When the bitstring ever specifies that CSO does not require headers
(dependent on VIOS vnic server changes), then this patch should be
removed and replaced with one that investigates the bitstring before
using send_subcrq_direct.

Byte Queue Limits depends on dql_completed being called once per tx
completion round in order to adjust its algorithm appropriately. The
dql->limit value is an approximation of the amount of bytes that the NIC
can consume per irq interval. If this approximation is too high then the
NIC will become over-saturated. Too low and the NIC will starve.
The dql->limit depends on dql->prev-* stats to calculate an optimal
value. If dql_completed() is called more than once per irq handler then
those prev-* values become unreliable (because they are not an accurate
representation of the previous state of the NIC) resulting in a
sub-optimal limit value.
Therefore, move the call to netdev_tx_completed_queue() to the end of
ibmvnic_complete_tx().
When performing 150 sessions of TCP rr (request-response 1 byte packets)
workloads, one could observe:
PREVIOUSLY: - limit and inflight values hovering around 130
- transaction rate of around 750k pps.
NOW: - limit rises and falls in response to inflight (130-900)
- transaction rate of around 1M pps (33% improvement)

Firmware supports two hcalls to send a sub-crq request:
H_SEND_SUB_CRQ_INDIRECT and H_SEND_SUB_CRQ. The indirect hcall allows
for submission of batched messages while the other hcall is limited to
only one message. This protocol is defined in PAPR section 17.2.3.3.
Previously, the ibmvnic xmit function only used the indirect hcall. This
allowed the driver to batch it's skbs. A single skb can occupy a few
entries per hcall depending on if FW requires skb header information or
not. The FW only needs header information if the packet is segmented.
By this logic, if an skb is not GSO then it can fit in one sub-crq
message and therefore is a candidate for H_SEND_SUB_CRQ.
Batching skb transmission is only useful when there are more packets
coming down the line (ie netdev_xmit_more is true).
As it turns out, H_SEND_SUB_CRQ induces less latency than
H_SEND_SUB_CRQ_INDIRECT. Therefore, use H_SEND_SUB_CRQ where
appropriate.
Small latency gains seen when doing TCP_RR_150 (request/response
workload). Ftrace results (graph-time=1):
Previous:

Previously when creating the header descriptors, the driver would:
1. allocate a temporary buffer on the stack (in build_hdr_descs_arr)
2. memcpy the header info into the temporary buffer (in build_hdr_data)
3. memcpy the temp buffer into a local variable (in create_hdr_descs)
4. copy the local variable into the return buffer (in create_hdr_descs)
Since, there is no opportunity for errors during this process, the temp
buffer is not needed and work can be done on the return buffer directly.
Repurpose build_hdr_data() to only calculate the header lengths. Rename
it to get_hdr_lens().
Edit create_hdr_descs() to read from the skb directly and copy directly
into the returned useful buffer.
The process now involves less memory and write operations while
also being more readable.

Use the header length helper functions rather than trying to calculate
it within the driver. There are defined functions for mac and network
headers (skb_mac_header_len and skb_network_header_len) but no such
function exists for the transport header length.
Also, hdr_data was memset during allocation to all 0's so no need to
memset again.

Previously, the driver would replenish the rx pool if the polling
function consumed less than the budget. The logic being that the driver
did not exhaust its budget so that must mean that the driver is not busy
and has cycles to spare for replenishing the pool.
So pool replenishment happens on every poll which did not consume
the budget. This can very costly during request-response tests.
In fact, an extra ~100pps can be seen in TCP_RR_150 tests when we remove
this conditional. Trace results (ftrace, graph-time=1) for the poll
function are below:
Previous results:
ibmvnic_poll = 64951846.0 us / 4167628.0 hits = AVG 15.58
replenish_rx_pool = 17602846.0 us / 4710437.0 hits = AVG 3.74
Now:
ibmvnic_poll = 57673941.0 us / 4791737.0 hits = AVG 12.04
replenish_rx_pool = 3938171.6 us / 4314.0 hits = AVG 912.88
While the replenish function takes longer, it is hit less frequently
meaning the ibmvnic_poll function, on average, is faster.
Furthermore, this change does not have a negative effect on
performance bandwidth/latency measurements.

Don't take HW USO path when packets can't be checksummed by device
This series addresses a recent regression report from syzbot [1].
After enabling UDP_SEGMENT for egress devices which don't support checksum
offload [2], we need to tighten down the checks which let packets take the
HW USO path.
The fix consists of two parts:
1. don't let devices offer USO without checksum offload, and
2. force software USO fallback in presence of IPv6 extension headers.

In commit 10154dbded6d ("udp: Allow GSO transmit from devices with no
checksum offload") we have intentionally allowed UDP GSO packets marked
CHECKSUM_NONE to pass to the GSO stack, so that they can be segmented and
checksummed by a software fallback when the egress device lacks these
features.
What was not taken into consideration is that a CHECKSUM_NONE skb can be
handed over to the GSO stack also when the egress device advertises the
tx-udp-segmentation / NETIF_F_GSO_UDP_L4 feature.
This will happen when there are IPv6 extension headers present, which we
check for in __ip6_append_data(). Syzbot has discovered this scenario,
producing a warning as below:

We are hitting the bad offload warning because when an egress device is
capable of handling segmentation offload requested by
skb_shinfo(skb)->gso_type, the chain of gso_segment callbacks won't produce
any segment skbs and return NULL. See the skb_gso_ok() branch in
{__udp,tcp,sctp}_gso_segment helpers.
To fix it, force a fallback to software USO when processing a packet with
IPv6 extension headers, since we don't know if these can checksummed by
all devices which offer USO.

UDP segmentation offload inherently depends on checksum offload. It should
not be possible to disable checksum offload while leaving USO enabled.
Enforce this dependency in code.
There is a single tx-udp-segmentation feature flag to indicate support for
both IPv4/6, hence the devices wishing to support USO must offer checksum
offload for both IP versions.

Currently ethtool_set_channel calls separate functions to check whether
the new channel number violates rss configuration or flow steering
configuration.
Very soon we need to check whether the new channel number violates
memory provider configuration as well.
To do all 3 checks cleanly, add a wrapper around
ethtool_get_max_rxnfc_channel() and ethtool_get_max_rxfh_channel(),
which does both checks. We can later extend this wrapper to add the
memory provider check in one place.
Note that in the current code, we put a descriptive genl error message
when we run into issues. To preserve the error message, we pass the
genl_info* to the common helper. The ioctl calls can pass NULL instead.

Commit 04d82a6d0881 ("binfmt_flat: allow not offsetting data start")
introduced a RISC-V specific variant of the FLAT format which does
not allocate any space for the (obsolete) array of shared library
pointers. However, it did not disable the code which initializes the
array, resulting in the corruption of sizeof(long) bytes before the DATA
segment, generally the end of the TEXT segment.
Introduce MAX_SHARED_LIBS_UPDATE which depends on the state of
CONFIG_BINFMT_FLAT_NO_DATA_START_OFFSET to guard the initialization of
the shared library pointer region so that it will only be initialized
if space is reserved for it.

The recursive aes-arm-bs module load situation reported by Russell King
is getting fixed in the crypto layer, but this in the meantime fixes the
"recursive load hangs forever" by just making the waiting for the first
module load be interruptible.
This should now match the old behavior before commit 9b9879fc0327
("modules: catch concurrent module loads, treat them as idempotent"),
which used the different "wait for module to be ready" code in
module_patient_check_exists().
End result: a recursive module load will still block, but now a signal
will interrupt it and fail the second module load, at which point the
first module will successfully complete loading.

Apart from the standard "configurations", "interfaces" and "alternate
interface settings" in USB, iOS devices also have a notion of
"modes". In different modes, the device exposes a different set of
available configurations.
Depending on the iOS version, and depending on the current mode, the
length and contents of the carrier state control message differs:
* 1 byte (seen on iOS 4.2.1, 8.4):
* 03: carrier off (mode 0)
* 04: carrier on (mode 0)
* 3 bytes (seen on iOS 10.3.4, 15.7.6):
* 03 03 03: carrier off (mode 0)
* 04 04 03: carrier on (mode 0)
* 4 bytes (seen on iOS 16.5, 17.6):
* 03 03 03 00: carrier off (mode 0)
* 04 03 03 00: carrier off (mode 1)
* 06 03 03 00: carrier off (mode 4)
* 04 04 03 04: carrier on (mode 0 and 1)
* 06 04 03 04: carrier on (mode 4)
Before this change, the driver always used the first byte of the
response to determine carrier state.
From this larger sample, the first byte seems to indicate the number of
available USB configurations in the current mode (with the exception of
the default mode 0), and in some cases (namely mode 1 and 4) does not
correlate with the carrier state.
Previous logic erroneously counted `04 03 03 00` as "carrier on" and
`06 04 03 04` as "carrier off" on iOS versions that support mode 1 and
mode 4 respectively.
Only modes 0, 1 and 4 expose the USB Ethernet interfaces necessary for
the ipheth driver.
Check the second byte of the control message where possible, and fall
back to checking the first byte on older iOS versions.

On iPhone 15 Pro Max one can observe periodic URBs with no payload
on the "bulk in" (RX) endpoint. These don't seem to do anything
meaningful. Reproduced on iOS 17.5.1 and 17.6.

nature of these zero-length URBs is so far unknown.

Rx URB length was already checked in ipheth_rcvbulk_callback_legacy()
and ipheth_rcvbulk_callback_ncm(), depending on the current mode.
The check in ipheth_rcvbulk_callback() was thus mostly a duplicate.
The only place in ipheth_rcvbulk_callback() where we care about the URB
length is for the initial control frame. These frames are always 4 bytes
long. This has been checked as far back as iOS 4.2.1 on iPhone 3G.
Remove the extraneous URB length check. For control frames, check for
the specific 4-byte length instead.

ipheth_sndbulk_callback() can submit carrier_work
as a part of its error handling. That means that
the driver must make sure that the work is cancelled
after it has made sure that no more URB can terminate
with an error condition.
Hence the order of actions in ipheth_close() needs
to be inverted.

scripts to include the feedback from the last version, but let me know
if there's anything missed. Questions and comments appreciated.
Thanks everyone!

Changes in v2:
- Removed qemu vm creation and related code
- Updated README.txt with examples of running the test with virtme
- Removed init.sh. run.sh now directly calls test.py
- Some clean up done with the return code handling since there is no
vm between the scripts anymore
- Imported ip python function in
tools/testing/selftests/net/lib/py/utils.py into test.py
- Adapted test.py to use the imported ip function, and removed the
local ip wrapper
- Some line wrap clean up
- Link to v1:

Jiri Slaby advises me that the preferred mechanism for declaring
string constants is static char arrays, so use that here.
This mostly reverts
commit 1692b9775e74 ("net: stmmac: xgmac: use #define for string constants")
That commit was a fix for
commit 46eba193d04f ("net: stmmac: xgmac: fix handling of DPP safety error for DMA channels").
The fix being replacing const char * with #defines in order to address
compilation failures observed on GCC 6 through 10.
Compile tested only.
No functional change intended.

Quite a lot of fixes have come in since the merge window, there's some
repetitive fixes over the Qualcomm drivers increasing the patch count,
along with a large batch of fixes from Cirrus. We also have some quirks
and some individual fixes.
