It's quite confusing in practice when it's possible to successfully
create a BPF token from BPF FS that didn't have any of delegate_xxx
mount options set up. While it's not wrong, it's actually more
meaningful to reject BPF_TOKEN_CREATE with specific error code (-ENOENT)
to let user-space know that no token delegation is setup up.
So, instead of creating empty BPF token that will be always ignored
because it doesn't have any of the allow_xxx bits set, reject it with
-ENOENT. If we ever need empty BPF token to be possible, we can support
that with extra flag passed into BPF_TOKEN_CREATE.

=== Motivation ===
Similar to reading from CO-RE bitfields, we need a CO-RE aware bitfield
writing wrapper to make the verifier happy.
Two alternatives to this approach are:
1. Use the upcoming `preserve_static_offset` [0] attribute to disable
CO-RE on specific structs.
2. Use broader byte-sized writes to write to bitfields.
(1) is a bit hard to use. It requires specific and not-very-obvious
annotations to bpftool generated vmlinux.h. It's also not generally
available in released LLVM versions yet.
(2) makes the code quite hard to read and write. And especially if
BPF_CORE_READ_BITFIELD() is already being used, it makes more sense to
to have an inverse helper for writing.
=== Implementation details ===
Since the logic is a bit non-obvious, I thought it would be helpful
to explain exactly what's going on.
To start, it helps by explaining what LSHIFT_U64 (lshift) and RSHIFT_U64
(rshift) is designed to mean. Consider the core of the
BPF_CORE_READ_BITFIELD() algorithm:
val <<= __CORE_RELO(s, field, LSHIFT_U64);
val = val >> __CORE_RELO(s, field, RSHIFT_U64);
Basically what happens is we lshift to clear the non-relevant (blank)
higher order bits. Then we rshift to bring the relevant bits (bitfield)
down to LSB position (while also clearing blank lower order bits). To
illustrate:
Start: ........XXX......
Lshift: XXX......00000000
Rshift: 00000000000000XXX
where `.` means blank bit, `0` means 0 bit, and `X` means bitfield bit.
After the two operations, the bitfield is ready to be interpreted as a
regular integer.
Next, we want to build an alternative (but more helpful) mental model
on lshift and rshift. That is, to consider:
* rshift as the total number of blank bits in the u64
* lshift as number of blank bits left of the bitfield in the u64
Take a moment to consider why that is true by consulting the above
diagram.
With this insight, we can now define the following relationship:
bitfield
_
| |
0.....00XXX0...00
| | | |
|______| | |
lshift | |
|____|
(rshift - lshift)
That is, we know the number of higher order blank bits is just lshift.
And the number of lower order blank bits is (rshift - lshift).
Finally, we can examine the core of the write side algorithm:
mask = (~0ULL << rshift) >> lshift; // 1
val = (val & ~mask) | ((nval << rpad) & mask); // 2
1. Compute a mask where the set bits are the bitfield bits. The first
left shift zeros out exactly the number of blank bits, leaving a
bitfield sized set of 1s. The subsequent right shift inserts the
correct amount of higher order blank bits.
2. On the left of the `|`, mask out the bitfield bits. This creates
0s where the new bitfield bits will go. On the right of the `|`,
bring nval into the correct bit position and mask out any bits
that fall outside of the bitfield. Finally, by bor'ing the two
halves, we get the final set of bits to write back.

virtio-net: support dynamic coalescing moderation
Now, virtio-net already supports per-queue moderation parameter
setting. Based on this, we use the linux dimlib to support
dynamic coalescing moderation for virtio-net.
Due to some scheduling issues, we only support and test the rx dim.
Some test results:
I. Sockperf UDP
=================================================
1. Env
rxq_0 with affinity to cpu_0.
2. Cmd
client: taskset -c 0 sockperf tp -p 8989 -i $IP -t 10 -m 16B
server: taskset -c 0 sockperf sr -p 8989
3. Result
dim off: 1143277.00 rxpps, throughput 17.844 MBps, cpu is 100%.
dim on: 1124161.00 rxpps, throughput 17.610 MBps, cpu is 83.5%.
=================================================
II. Redis
=================================================
1. Env
There are 8 rxqs, and rxq_i with affinity to cpu_i.
2. Result
When all cpus are 100%, ops/sec of memtier_benchmark client is
dim off: 978437.23
dim on: 1143638.28
=================================================
III. Nginx
=================================================
1. Env
There are 8 rxqs and rxq_i with affinity to cpu_i.
2. Result
When all cpus are 100%, requests/sec of wrk client is
dim off: 877931.67
dim on: 1019160.31
=================================================
IV. Latency of sockperf udp
=================================================
1. Rx cmd
taskset -c 0 sockperf sr -p 8989
2. Tx cmd
taskset -c 0 sockperf pp -i ${ip} -p 8989 -t 10
After running this cmd 5 times and averaging the results,
3. Result
dim off: 17.7735 usec
dim on: 18.0110 usec

Based on the tcp man page, if TCP_NODELAY is set, it disables Nagle's algorithm
and packets are sent as soon as possible. However in the `tcp_push` function
where autocorking is evaluated the `nonagle` value set by TCP_NODELAY is not
considered which can trigger unexpected corking of packets and induce delays.
For example, if two packets are generated as part of a server's reply, if the
first one is not transmitted on the wire quickly enough, the second packet can
trigger the autocorking in `tcp_push` and be delayed instead of sent as soon as
possible. It will either wait for additional packets to be coalesced or an ACK
from the client before transmitting the corked packet. This can interact badly
if the receiver has tcp delayed acks enabled, introducing 40ms extra delay in
completion times. It is not always possible to control who has delayed acks
set, but it is possible to adjust when and how autocorking is triggered.
Patch prevents autocorking if the TCP_NODELAY flag is set on the socket.
Patch has been tested using an AWS c7g.2xlarge instance with Ubuntu 22.04 and
Apache Tomcat 9.0.83 running the basic servlet below:
import java.io.IOException;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class HelloWorldServlet extends HttpServlet {
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=utf-8");
OutputStreamWriter osw = new OutputStreamWriter(response.getOutputStream(),"UTF-8");
String s = "a".repeat(3096);
osw.write(s,0,s.length());
osw.flush();
}
}
Load was applied using wrk2 (https://github.com/kinvolk/wrk2) from an AWS
c6i.8xlarge instance. With the current auto-corking behavior and TCP_NODELAY
set an additional 40ms latency from P99.99+ values are observed. With the
patch applied we see no occurrences of 40ms latencies. The patch has also been
tested with iperf and uperf benchmarks and no regression was observed.

net: phy: at803x: cleanup
The intention of this big series is to try to cleanup the big
at803x PHY driver.
It currently have 3 different family of PHY in it. at803x, qca83xx
and qca808x.
The current codebase required lots of cleanup and reworking to
make the split possible as currently there is a greater use of
adding special function matching the phy_id.
This has been reworked to make the function actually generic
and make the change only in more specific one. The result
is the addition of micro additional function but that is for good
as it massively simplify splitting the driver later.
Consider that this is all in preparation for the addition of
qca807x PHY driver that will also uso some of the functions of
at803x.
Subsequent series will come with the actual PHY split and other
required cleanup. This is only to start the process with minor
changes.
Changes v4:
- Improve at8031_probe function
Changes v3:
- Add Reviewed-by tag from Andrew
- Split patch 10 (at8031 rename) to rename and move
Changes v2:
- Drop split part due to series too big
- Split changes even more
- Fix problem pointed out by Russell (flawed reworked function logic)
- Add Reviewed-by tag from Andrew
- Minor rework to prevent further code duplication for cdt

Detection logic is changed, we check if the clk 25m mask is set and if
it's not zero, we assume the qca,clk-out-frequency property is set.
The property is checked in the generic at803x_parse_dt called by
at803x_probe.

Move specific at8031 config_intr bits to dedicated function to make

This is needed in preparation for PHY driver split as qca8081 share the

Move specific at8031 WOL enable/disable to dedicated function to make
at803x_set_wol more generic.
This is needed in preparation for PHY driver split as qca8081 share the
same function to toggle WOL settings.
In this new implementation WOL module in at8031 is enabled after the
generic interrupt is setup. This should not cause any problem as the
WOL_INT has a separate implementation and only relay on MAC bits.

The function and the struct related to hw_stats were specific to qca83xx
PHY but were called following the convention in the driver of calling
everything with at803x prefix.
To better organize the code, rename these function a more specific name
to better describe that they are specific to 83xx PHY family.

Mode supported is currently reported to the user exactly the same, as
the current mode. That's because mode changing is not implemented.
Remove the leftover mode_supported() op and use mode_get() to fill up
the supported mode exposed to user.
One, if even, mode changing is going to be introduced, this could be
very easily taken back. In the meantime, prevent drivers form
implementing this in wrong way (as for example recent netdevsim
implementation attempt intended to do).
