This commit adds using the need_wakeup flag to the xdpsock sample
application. It is turned on by default as we think it is a feature
that seems to always produce a performance benefit, if the application
has been written taking advantage of it. It can be turned off in the
sample app by using the '-m' command line option.
The txpush and l2fwd sub applications have also been updated to
support poll() with multiple sockets.

In-Reply-To: <1565767643-4908-1-git-send-email-magnus.karlsson@intel.com>
This commit adds support for the new need_wakeup flag in AF_XDP. The
xsk_socket__create function is updated to handle this and a new
function is introduced called xsk_ring_prod__needs_wakeup(). This
function can be used by the application to check if Rx and/or Tx
processing needs to be explicitly woken up.

This patch adds support for the need_wakeup feature of AF_XDP. If the
application has told the kernel that it might sleep using the new bind
flag XDP_USE_NEED_WAKEUP, the driver will then set this flag if it has
no more buffers on the NIC Rx ring and yield to the application. For
Tx, it will set the flag if it has no outstanding Tx completion
interrupts and return to the application.

* [PATCH bpf-next v4 2/8] xsk: add support for need_wakeup flag in AF_XDP rings

In-Reply-To: <1565767643-4908-1-git-send-email-magnus.karlsson@intel.com>
This commit adds support for a new flag called need_wakeup in the
AF_XDP Tx and fill rings. When this flag is set, it means that the
application has to explicitly wake up the kernel Rx (for the bit in
the fill ring) or kernel Tx (for bit in the Tx ring) processing by
issuing a syscall. Poll() can wake up both depending on the flags
submitted and sendto() will wake up tx processing only.
The main reason for introducing this new flag is to be able to
efficiently support the case when application and driver is executing
on the same core. Previously, the driver was just busy-spinning on the
fill ring if it ran out of buffers in the HW and there were none on
the fill ring. This approach works when the application is running on
another core as it can replenish the fill ring while the driver is
busy-spinning. Though, this is a lousy approach if both of them are
running on the same core as the probability of the fill ring getting
more entries when the driver is busy-spinning is zero. With this new
feature the driver now sets the need_wakeup flag and returns to the
application. The application can then replenish the fill queue and
then explicitly wake up the Rx processing in the kernel using the
syscall poll(). For Tx, the flag is only set to one if the driver has
no outstanding Tx completion interrupts. If it has some, the flag is
zero as it will be woken up by a completion interrupt anyway.
As a nice side effect, this new flag also improves the performance of
the case where application and driver are running on two different
cores as it reduces the number of syscalls to the kernel. The kernel
tells user space if it needs to be woken up by a syscall, and this
eliminates many of the syscalls.
This flag needs some simple driver support. If the driver does not
support this, the Rx flag is always zero and the Tx flag is always
one. This makes any application relying on this feature default to the
old behaviour of not requiring any syscalls in the Rx path and always
having to call sendto() in the Tx path.
For backwards compatibility reasons, this feature has to be explicitly
turned on using a new bind flag (XDP_USE_NEED_WAKEUP). I recommend
that you always turn it on as it so far always have had a positive
performance impact.
The name and inspiration of the flag has been taken from io_uring by
Jens Axboe. Details about this feature in io_uring can be found in
http://kernel.dk/io_uring.pdf, section 8.3.

In-Reply-To: <1565767643-4908-1-git-send-email-magnus.karlsson@intel.com>
This commit replaces ndo_xsk_async_xmit with ndo_xsk_wakeup. This new
ndo provides the same functionality as before but with the addition of
a new flags field that is used to specifiy if Rx, Tx or both should be
woken up. The previous ndo only woke up Tx, as implied by the
name. The i40e and ixgbe drivers (which are all the supported ones)
are updated with this new interface.
This new ndo will be used by the new need_wakeup functionality of XDP
sockets that need to be able to wake up both Rx and Tx driver
processing.

* [PATCH bpf-next v4 0/8] add need_wakeup flag to the AF_XDP rings
From: Magnus Karlsson @ 2019-08-14 7:27 UTC (permalink / raw)
To: magnus.karlsson, bjorn.topel, ast, daniel, netdev, brouer,
maximmi
Cc: bpf, bruce.richardson, ciara.loftus, jakub.kicinski, xiaolong.ye,
qi.z.zhang, sridhar.samudrala, kevin.laatz, ilias.apalodimas,
jonathan.lemon, kiran.patil, axboe, maciej.fijalkowski,
maciejromanfijalkowski, intel-wired-lan
This patch set adds support for a new flag called need_wakeup in the
AF_XDP Tx and fill rings. When this flag is set by the driver, it
means that the application has to explicitly wake up the kernel Rx
(for the bit in the fill ring) or kernel Tx (for bit in the Tx ring)
processing by issuing a syscall. Poll() can wake up both and sendto()
will wake up Tx processing only.
The main reason for introducing this new flag is to be able to
efficiently support the case when application and driver is executing
on the same core. Previously, the driver was just busy-spinning on the
fill ring if it ran out of buffers in the HW and there were none to
get from the fill ring. This approach works when the application and
driver is running on different cores as the application can replenish
the fill ring while the driver is busy-spinning. Though, this is a
lousy approach if both of them are running on the same core as the
probability of the fill ring getting more entries when the driver is
busy-spinning is zero. With this new feature the driver now sets the
need_wakeup flag and returns to the application. The application can
then replenish the fill queue and then explicitly wake up the Rx
processing in the kernel using the syscall poll(). For Tx, the flag is
only set to one if the driver has no outstanding Tx completion
interrupts. If it has some, the flag is zero as it will be woken up by
a completion interrupt anyway. This flag can also be used in other
situations where the driver needs to be woken up explicitly.
As a nice side effect, this new flag also improves the Tx performance
of the case where application and driver are running on two different
cores as it reduces the number of syscalls to the kernel. The kernel
tells user space if it needs to be woken up by a syscall, and this
eliminates many of the syscalls. The Rx performance of the 2-core case
is on the other hand slightly worse, since there is a need to use a
syscall now to wake up the driver, instead of the driver
busy-spinning. It does waste less CPU cycles though, which might lead
to better overall system performance.
This new flag needs some simple driver support. If the driver does not
support it, the Rx flag is always zero and the Tx flag is always
one. This makes any application relying on this feature default to the
old behavior of not requiring any syscalls in the Rx path and always
having to call sendto() in the Tx path.
For backwards compatibility reasons, this feature has to be explicitly
turned on using a new bind flag (XDP_USE_NEED_WAKEUP). I recommend
that you always turn it on as it has a large positive performance
impact for the one core case and does not degrade 2 core performance
and actually improves it for Tx heavy workloads.
Here are some performance numbers measured on my local,
non-performance optimized development system. That is why you are
seeing numbers lower than the ones from Björn and Jesper. 64 byte
packets at 40Gbit/s line rate. All results in Mpps. Cores == 1 means
that both application and driver is executing on the same core. Cores
== 2 that they are on different cores.
Applications
need_wakeup cores txpush rxdrop l2fwd
---------------------------------------------------------------
n 1 0.07 0.06 0.03
y 1 21.6 8.2 6.5
n 2 32.3 11.7 8.7
y 2 33.1 11.7 8.7
Overall, the need_wakeup flag provides the same or better performance
in all the micro-benchmarks. The reduction of sendto() calls in txpush
is large. Only a few per second is needed. For l2fwd, the drop is 50%
for the 1 core case and more than 99.9% for the 2 core case. Do not
know why I am not seeing the same drop for the 1 core case yet.
The name and inspiration of the flag has been taken from io_uring by
Jens Axboe. Details about this feature in io_uring can be found in
http://kernel.dk/io_uring.pdf, section 8.3. It also addresses most of
the denial of service and sendto() concerns raised by Maxim
Mikityanskiy in https://www.spinics.net/lists/netdev/msg554657.html.
The typical Tx part of an application will have to change from:
ret = sendto(fd,....)
to:
if (xsk_ring_prod__needs_wakeup(&xsk->tx))
ret = sendto(fd,....)
and th Rx part from:
rcvd = xsk_ring_cons__peek(&xsk->rx, BATCH_SIZE, &idx_rx);
if (!rcvd)
return;
to:
rcvd = xsk_ring_cons__peek(&xsk->rx, BATCH_SIZE, &idx_rx);
if (!rcvd) {
if (xsk_ring_prod__needs_wakeup(&xsk->umem->fq))
ret = poll(fd,.....);
return;
}
v3 -> v4:
* Maxim found a possible race in the Tx part of the driver. The
setting of the flag needs to happen before the sending, otherwise it
might trigger this race. Fixed in ixgbe and i40e driver.
* Mellanox support contributed by Maxim
* Removed the XSK_DRV_CAN_SLEEP flag as it was not used
anymore. Thanks to Sridhar for discovering this.
* For consistency the feature is now always called need_wakeup. There
were some places where it was referred to as might_sleep, but they
have been removed. Thanks to Sridhar for spotting.
* Fixed some typos in the commit messages
v2 -> v3:
* Converted the Mellanox driver to the new ndo in patch 1 as pointed out
by Maxim
* Fixed the compatibility code of XDP_MMAP_OFFSETS so it now works.
v1 -> v2:
* Fixed bisectability problem pointed out by Jakub
* Added missing initiliztion of the Tx need_wakeup flag to 1
This patch has been applied against commit b753c5a7f99f ("Merge branch 'r8152-RX-improve'")
Structure of the patch set:
Patch 1: Replaces the ndo_xsk_async_xmit with ndo_xsk_wakeup to
support waking up both Rx and Tx processing

Yeah, regex, but not only. Note `-o' in the `grep' arguments, it returns
only matched piece of a string and the second `cut' is not needed.

Right, `-n' is not a good one, `-V' is much better since it's intended
to sort specifically versions:
% printf "0.1.2\n0.1.12\n0.1.11\n"
0.1.2
0.1.12
0.1.11
% printf "0.1.2\n0.1.12\n0.1.11\n" | sort -cV
sort: -:3: disorder: 0.1.11
% printf "0.1.2\n0.1.12\n0.1.11\n" | sort -V
0.1.2
0.1.11
0.1.12
The reason I brought this up is the version string can be an arbitrary string
and for example glibc does this:
% grep -Eo '^\s+GLIBC_\S+' sysdeps/unix/sysv/linux/Versions | tail -n 3
GLIBC_2.29
GLIBC_2.30
GLIBC_PRIVATE
I agree though that it's not a problem with the current version script
structure and it should be fine to postpone adding some kind of sorting till
the time this structure is changed (if at all).

Okay. If this is working, then you should properly test and see if the DROP

Felix, so I cannot check.

* [PATCH] net: myri10ge: fix memory leaks
From: Wenwen Wang @ 2019-08-14 6:38 UTC (permalink / raw)
To: Wenwen Wang
Cc: Chris Lee, David S. Miller,
open list:MYRICOM MYRI-10G 10GbE DRIVER (MYRI10GE), open list
In myri10ge_probe(), myri10ge_alloc_slices() is invoked to allocate slices
related structures. Later on, myri10ge_request_irq() is used to get an irq.
However, if this process fails, the allocated slices related structures are
not deallocated, leading to memory leaks. To fix this issue, revise the
target label of the goto statement to 'abort_with_slices'.

[-- Attachment #1.1: Type: text/plain, Size: 6110 bytes --]
Hello David,
this is a pull request for net-next/master consisting of 41 patches.
The first two patches are for the kvaser_pciefd driver: Christer Beskow
removes unnecessary code in the kvaser_pciefd_pwm_stop() function,
YueHaibing removes the unused including of <linux/version.h>.
In the next patch YueHaibing also removes the unused including of
<linux/version.h> in the f81601 driver.
In the ti_hecc driver the next 6 patches are by me and fix checkpatch
warnings. YueHaibing's patch removes an unused variable in the
ti_hecc_mailbox_read() function.
The next 6 patches all target the xilinx_can driver. Anssi Hannula's
patch fixes a chip start failure with an invalid bus. The patch by
Venkatesh Yadav Abbarapu skips an error message in case of a deferred
probe. The 3 patches by Appana Durga Kedareswara rao fix the RX and TX
path for CAN-FD frames. Srinivas Neeli's patch fixes the bit timing
calculations for CAN-FD.
The next 12 patches are by me and several checkpatch warnings in the
af_can, raw and bcm components.
Thomas Gleixner provides a patch for the bcm, which switches the timer
to HRTIMER_MODE_SOFT and removes the hrtimer_tasklet.
Then 6 more patches by me for the gw component, which fix checkpatch
warnings, followed by 2 patches by Oliver Hartkopp to add CAN-FD
support.
The vcan driver gets 3 patches by me, fixing checkpatch warnings.
And finally a patch by Andre Hartmann to fix typos in CAN's netlink
header.
regards,
Marc

* [net PATCH] net: tls, fix sk_write_space NULL write when tx disabled
From: John Fastabend @ 2019-08-14 5:31 UTC (permalink / raw)
To: jakub.kicinski, davem; +Cc: ying.xue, netdev, john.fastabend, andreyknvl
The ctx->sk_write_space pointer is only set when TLS tx mode is enabled.
When running without TX mode its a null pointer but we still set the
sk sk_write_space pointer on close().
Fix the close path to only overwrite sk->sk_write_space when the current
pointer is to the tls_write_space function indicating the tls module should
clean it up properly as well.

* [PATCH v2 bpf-next] libbpf: make libbpf.map source of truth for libbpf version
From: Andrii Nakryiko @ 2019-08-14 5:10 UTC (permalink / raw)
To: bpf, netdev, ast, daniel
Cc: andrii.nakryiko, kernel-team, Andrii Nakryiko, Andrey Ignatov
Currently libbpf version is specified in 2 places: libbpf.map and
Makefile. They easily get out of sync and it's very easy to update one,
but forget to update another one. In addition, Github projection of
libbpf has to maintain its own version which has to be remembered to be
kept in sync manually, which is very error-prone approach.
This patch makes libbpf.map a source of truth for libbpf version and
uses shell invocation to parse out correct full and major libbpf version
to use during build. Now we need to make sure that once new release
cycle starts, we need to add (initially) empty section to libbpf.map
with correct latest version.
This also will make it possible to keep Github projection consistent
with kernel sources version of libbpf by adopting similar parsing of
version from libbpf.map.
v1->v2:
- eager version vars evaluation (Jakub);
- simplified version regex (Andrey);

[Y.b. Lu] As Andrew said, other switches could identify PTP messages and forward to CPU for processing.
https://patchwork.ozlabs.org/patch/1145627/
I'm also wondering whether there is common method in linux to address your questions.
If no, I think trapping all PTP messages on all ports to CPU could be used for now.
If users require PTP synchronization, they actually don’t want a non-aware PTP switch.
I once see other ocelot code configure ptp trap rules in ioctl timestamping setting. But I don’t think it's proper either.
Enable timestamping doesn’t mean we want to trap PTP messages.
>
> What if do not want this on all ports?
[Y.b. Lu] Actually I don’t think there should be difference of handling PTP messages on each port.
You don’t need to run PTP protocol application on the specific port if you don’t want.

[Y.b. Lu] You're right. But actually for PTP network, all PTP devices should run PTP protocol on it.
Of course, it's better to have a way to configure it as non-aware PTP switch.

The config is attached. just run trace_ns_info and you
can reproduce the issue.

LIBBPF_VERSION is used below, but combining your suggestion with
Jakub's eager evaluation, I can use just LIBBPF_VERSION and drop
BPF_FULL_VERSION altogether.

Ah, you mean making regex simpler? Yeah, I originally intended to
extract major, patch, and extra version, but ralized patch and extra
are not used for anything. I'll simplify regex. But second `cut -d' '
-f1` is still needed to drop " {".
Regarding sorting. I don't think it's necessary, as I can't imagine
having non-ordered libbpf.map. Even more so, sort -nr doesn't sort
versions like these correctly anyway:
0.1.2
0.1.12
So this will just give us false sense of correctness, while being a "time bomb".

This is actually fixing a version. Current libbpf version in bpf-next
is 0.0.5, it just was never updated in Makefile.

[Y.b. Lu] PTP messages over Ethernet will use two multicast addresses.
01-80-C2-00-00-0E for peer delay messages.
01-1B-19-00-00-00 for other messages.
But only 01-80-C2-00-00-0E could be handled by hardware filter for BPDU frames (01-80-C2-00-00-0x).
For PTP messages handling, trapping them to CPU through VCAP IS2 is the suggested way by Ocelot/Felix.
I have a question since you are experts.
For other switches, whether they are always trapping PTP messages to CPU?
Is there any common method in linux to configure switch to select trapping or just forwarding PTP messages?
Like Allan's comments in new version patch. I have no idea.

[Y.b. Lu] Sorry. I missed your previous comments on the TRAP action.
With my configuration in the patch, it indeed worked. Maybe it was because "the CPU port is not touched by MASK_MODE" which I saw in RM.
I will try your suggestion too. It sound more proper.
