The functions that are used for PF VSI/netdev setup will also be used
for SR-IOV support. To allow reuse of these functions, move these
functions out of ice_main.c to ice_common.c/ice_lib.c
This move is done across multiple patches. Each patch moves a few
functions and may have minor adjustments. For example, a function that was
previously static in ice_main.c will be made non-static temporarily in
its new location to allow the driver to build cleanly. These adjustments
will be removed in subsequent patches where more code is moved out of
ice_main.c
In this particular patch, the following functions were moved out of
ice_main.c:
int ice_add_mac_to_list
ice_free_fltr_list
ice_stat_update40
ice_stat_update32
ice_update_eth_stats
ice_vsi_add_vlan
ice_vsi_kill_vlan

The system image guid is a read-only field which is used by the TC
offloads code to determine if two mlx5 devices belong to the same
ASIC while adding flows.
Read this once and save it on the core device rather than querying each
time an offloaded flow is added.

Currently we practically never report checksum unnecessary, because

Increased the amount of channels the representors can open to be the
amount of CPUs. The default amount opened remains one.
Used the standard NIC netdev functions to:
* Set RSS params when building the representors' params.
* Setup an indirect TIR and RQT for the representors upon
initialization.
* Create a TTC flow table for the representors' indirect TIR (when
creating the TTC table, mlx5e_set_ttc_basic_params() is not called,
in order to avoid setting the inner_ttc param, which is not needed).
Added ethtool control to the representors for setting and querying
the amount of open channels. Additionally, included logic in the
representors' ethtool set channels handler which controls a
representor's vport rx rule, so that if there is one open channel
the rx rule steers traffic to the representor's direct TIR, whereas
if there is more than one channel, the rx rule steers traffic to the
new TTC flow table.

Enabled checksum and TSO offloads for the representors, in
order to increase their performance, which is required to
increase the performance of flows that cannot be offloaded.
Checksum offloads contribute to a general acceleration of all
traffic (to around 150%), whereas the TSO offload contributes
to a prominent acceleration of the representor's TX for traffic
flows with larger than MTU sized packets (to around 200%). This
is the usual case for TCP streams, as the PF, which serves as
the uplink representor, and the VF representors employ GRO before
forwarding the packets to the representor.
GRO was enabled implicitly for the representors beforehand, and
is explicitly enabled here to ensure that the representors preserve
the performance boost it provides (of around 200%) when working in
tandem with the TSO offload by the forwardee, which is the standard
case as both the PF and the VF representors employ HW TSO.
The impact of these changes can be seen in the following
measurements taken on a setup of a VM over a VF, connected
to OVS via the VF representor, to an external host:
Before current changes:
TCP Throughput [Gb/s]
External host to VM ~ 10.5
VM to external host ~ 23.5
With just checksum offloads enabled:
TCP Throughput [Gb/s]
External host to VM ~ 14.9
VM to external host ~ 28.5
With the TSO offload also enabled:
TCP Throughput [Gb/s]
External host to VM ~ 30.5

The representors' RQ size was not large enough for them to achieve
high enough performance, and therefore needed to be enlarged, while
suffering a minimum hit to its memory usage. To achieve this the
representors RQ size was increased, and its type was changed to be a
striding RQ if it is supported.
Towards that goal the following changes were made:
* Extracted the sequence for setting the standard netdev's RQ parmas
into a function
* Replaced the sequence for setting the representor's RQ params with
the standard sequence
The impact of this change can be seen in the following measurements
taken on a setup of a VM over a VF, connected to OVS via the VF
representor, to an external host:
Before current change:
TCP Throughput [Gb/s]
VM to external host ~ 7.2
With the current change (measured with a striding RQ):
TCP Throughput [Gb/s]
VM to external host ~ 23.5
Each representor now consumes 2 [MB] of memory for its packet
buffers.

Structure 'tls_rec' contains sg_aead_in and sg_aead_out which point
to a aad_space and then chain scatterlists sg_plaintext_data,
sg_encrypted_data respectively. Rather than using chained scatterlists
for plaintext and encrypted data in aead_req, it is efficient to store
aad_space in sg_encrypted_data and sg_plaintext_data itself in the
first index and get rid of sg_aead_in, sg_aead_in and further chaining.
This requires increasing size of sg_encrypted_data & sg_plaintext_data
arrarys by 1 to accommodate entry for aad_space. The code which uses
sg_encrypted_data and sg_plaintext_data has been modified to skip first
index as it points to aad_space.

Jon Maloy says:
====================
tipc: make connection setup more robust
In this series we make a few improvements to the connection setup and
probing mechanism, culminating in the last commit where we make it
possible for a client socket to make multiple setup attempts in case
it encounters receive buffer overflow at the listener socket.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
|
|
Default socket receive buffer size for a listener socket is 2Mb. For
each arriving empty SYN, the linux kernel allocates a 768 bytes buffer.
This means that a listener socket can serve maximum 2700 simultaneous
empty connection setup requests before it hits a receive buffer
overflow, and much fewer if the SYN is carrying any significant
amount of data.
When this happens the setup request is rejected, and the client
receives an ECONNREFUSED error.
This commit mitigates this problem by letting the client socket try to
retransmit the SYN message multiple times when it sees it rejected with
the code TIPC_ERR_OVERLOAD. Retransmission is done at random intervals
in the range of [100 ms, setup_timeout / 4], as many times as there is
room for within the setup timeout limit.

Messages intended for intitating a connection are currently
indistinguishable from regular datagram messages. The TIPC
protocol specification defines bit 17 in word 0 as a SYN bit
to allow sanity check of such messages in the listening socket,
but this has so far never been implemented.
We do that in this commit.

The function tipc_msg_reverse() is reversing the header of a message
while reusing the original buffer. We have seen at several occasions
that this may have unfortunate side effects when the buffer to be
reversed is a clone.
In one of the following commits we will again need to reverse cloned
buffers, so this is the right time to permanently eliminate this
problem. In this commit we let the said function always consume the
original buffer and replace it with a new one when applicable.

Previously TCP initial receive buffer is ~87KB by default and
the initial receive window is ~29KB (20 MSS). This patch changes
the two numbers to 128KB and ~64KB (rounding down to the multiples
of MSS) respectively. The patch also simplifies the calculations s.t.
the two numbers are directly controlled by sysctl tcp_rmem[1]:
1) Initial receiver buffer budget (sk_rcvbuf): while this should
be configured via sysctl tcp_rmem[1], previously tcp_fixup_rcvbuf()
always override and set a larger size when a new connection
establishes.
2) Initial receive window in SYN: previously it is set to 20
packets if MSS <= 1460. The number 20 was based on the initial
congestion window of 10: the receiver needs twice amount to
avoid being limited by the receive window upon out-of-order
delivery in the first window burst. But since this only
applies if the receiving MSS <= 1460, connection using large MTU
(e.g. to utilize receiver zero-copy) may be limited by the
receive window.
With this patch TCP memory configuration is more straight-forward and
more properly sized to modern high-speed networks by default. Several
popular stacks have been announcing 64KB rwin in SYNs as well.
