2019-05-23net: ll_temac: Do not make promiscuous mode sticky on multicastEsben Haabendal1-7/+0
When user has requested IFF_ALLMULTI or have set more than 4 multicast addresses, we should just use promiscuous mode, but not set it in flags, as it causes the interface to stay in promiscuous mode even when the non-IFF_PROMISC condition that caused promiscuous mode to be enabled has gone away.

All LXT PHYs implement the standard "power down" bit 11 of BMCR, so this patch adds support using the generic genphy_{suspend,resume} functions added by commit 0f0ca340e57b ("phy: power management support").

2019-05-22hv_sock: perf: loop in send() to maximize bandwidthSunil Muthuswamy1-14/+31
Currently, the hv_sock send() iterates once over the buffer, puts data into the VMBUS channel and returns. It doesn't maximize on the case when there is a simultaneous reader draining data from the channel. In such a case, the send() can maximize the bandwidth (and consequently minimize the cpu cycles) by iterating until the channel is found to be full. Perf data: Total Data Transfer: 10GB/iteration Single threaded reader/writer, Linux hvsocket writer with Windows hvsocket reader Packet size: 64KB CPU sys time was captured using the 'time' command for the writer to send 10GB of data. 'Send Buffer Loop' is with the patch applied. The values below are over 10 iterations. |--------------------------------------------------------| | | Current | Send Buffer Loop | |--------------------------------------------------------| | | Throughput | CPU sys | Throughput | CPU sys | | | (MB/s) | time (s) | (MB/s) | time (s) | |--------------------------------------------------------| | Min | 407 | 7.048 | 401 | 5.958 | |--------------------------------------------------------| | Max | 455 | 7.563 | 542 | 6.993 | |--------------------------------------------------------| | Avg | 440 | 7.411 | 451 | 6.639 | |--------------------------------------------------------| | Median | 446 | 7.417 | 447 | 6.761 | |--------------------------------------------------------| Observation: 1. The avg throughput doesn't really change much with this change for this scenario. This is most probably because the bottleneck on throughput is somewhere else. 2. The average system (or kernel) cpu time goes down by 10%+ with this change, for the same amount of data transfer.

2019-05-22hv_sock: perf: Allow the socket buffer size options to influence the actual socket buffersSunil Muthuswamy1-10/+40
Currently, the hv_sock buffer size is static and can't scale to the bandwidth requirements of the application. This change allows the applications to influence the socket buffer sizes using the SO_SNDBUF and the SO_RCVBUF socket options. Few interesting points to note: 1. Since the VMBUS does not allow a resize operation of the ring size, the socket buffer size option should be set prior to establishing the connection for it to take effect. 2. Setting the socket option comes with the cost of that much memory being reserved/allocated by the kernel, for the lifetime of the connection. Perf data: Total Data Transfer: 1GB Single threaded reader/writer Results below are summarized over 10 iterations.

2019-05-22selftests: pmtu: Simplify cleanup and namespace namesDavid Ahern1-9/+8
The point of the pause-on-fail argument is to leave the setup as is after a test fails to allow a user to debug why it failed. Move the cleanup after posting the result to the user to make it so. Random names for the namespaces are not user friendly when trying to debug a failure. Make them simpler and more direct for the tests. Run cleanup at the beginning to ensure they are cleaned up if they already exist. Remove cleanup_done.

2019-05-22net: phy: dp83867: Rework delay rgmii delay handlingTrent Piepho1-12/+66
The code was assuming the reset default of the delay control register was to have delay disabled. This is what the datasheet shows as the register's initial value. However, that's not actually true: the default is controlled by the PHY's pin strapping. If the interface mode is selected as RX or TX delay only, insure the other direction's delay is disabled. If the interface mode is just "rgmii", with neither TX or RX internal delay, one might expect that the driver should disable both delays. But this is not what the driver does. It leaves the setting at the PHY's strapping's default. And that default, for no pins with strapping resistors, is to have delay enabled and 2.00 ns. Rather than change this behavior, I've kept it the same and documented it. No delay will most likely not work and will break ethernet on any board using "rgmii" mode. If the board is strapped to have a delay and is configured to use "rgmii" mode a warning is generated that "rgmii-id" should have been used. Also validate the delay values and fail if they are not in range.

2019-05-22net: phy: dp83867: Add ability to disable output clockTrent Piepho1-9/+28
Generally, the output clock pin is only used for testing and only serves as a source of RF noise after this. It could be used to daisy-chain PHYs, but this is uncommon. Since the PHY can disable the output, make doing so an option. I do this by adding another enumeration to the allowed values of ti,clk-output-sel. The code was not using the value DP83867_CLK_O_SEL_REF_CLK as one might expect: to select the REF_CLK as the output. Rather it meant "keep clock output setting as is", which, depending on PHY strapping, might not be outputting REF_CLK. Change this so DP83867_CLK_O_SEL_REF_CLK means enable REF_CLK output. Omitting the property will leave the setting as is (which was the previous behavior in this case). Out of range values were silently converted into DP83867_CLK_O_SEL_REF_CLK. Change this so they generate an error.

The clock output is generally only used for testing and development and not used to daisy-chain PHYs. It's just a source of RF noise afterward. Add a mux value for "off". I've added it as another enumeration to the output property. In the actual PHY, the mux and the output enable are independently controllable. However, it doesn't seem useful to be able to describe the mux setting when the output is disabled. Document that PHY's default setting will be left as is if the property is omitted.

The crash happens roughly 125..130ms after the disconnect. This correlates with the 'delay' timer that is started on certain USB tx/rx errors in the URB completion handler. The problem is a race of usbnet_stop() with usbnet_start_xmit(). In usbnet_stop() we call usbnet_terminate_urbs() to cancel all URBs in flight. This only makes sense if no new URBs are submitted concurrently, though. But the usbnet_start_xmit() can run at the same time on another CPU which almost unconditionally submits an URB. The error callback of the new URB will then schedule the timer after it was already stopped. The fix adds a check if the tx queue is stopped after the tx list lock has been taken. This should reliably prevent the submission of new URBs while usbnet_terminate_urbs() does its job. The same thing is done on the rx side even though it might be safe due to other flags that are checked there. Signed-off-by: Jan Klötzke <Jan.Kloetzke@preh.de> Signed-off-by: David S.

2019-05-21ipv6: Consider sk_bound_dev_if when binding a raw socket to an addressMike Manning1-0/+2
IPv6 does not consider if the socket is bound to a device when binding to an address. The result is that a socket can be bound to eth0 and then bound to the address of eth1. If the device is a VRF, the result is that a socket can only be bound to an address in the default VRF. Resolve by considering the device if sk_bound_dev_if is set.

2019-05-21usbnet: ipheth: fix racing conditionBernd Eckstein1-1/+2
Fix a racing condition in ipheth.c that can lead to slow performance. Bug: In ipheth_tx(), netif_wake_queue() may be called on the callback ipheth_sndbulk_callback(), _before_ netif_stop_queue() is called. When this happens, the queue is stopped longer than it needs to be, thus reducing network performance. Fix: Move netif_stop_queue() in front of usb_submit_urb(). Now the order is always correct. In case, usb_submit_urb() fails, the queue is woken up again as callback will not fire. Testing: This racing condition is usually not noticeable, as it has to occur very frequently to slowdown the network. The callback from the USB is usually triggered slow enough, so the situation does not appear. However, on a Ubuntu Linux on VMWare Workstation, running on Windows 10, the we loose the race quite often and the following speedup can be noticed: Without this patch: Download: 4.10 Mbit/s, Upload: 4.01 Mbit/s With this patch: Download: 36.23 Mbit/s, Upload: 17.61 Mbit/s Signed-off-by: Oliver Zweigle <Oliver.Zweigle@faro.com> Signed-off-by: Bernd Eckstein <3ernd.Eckstein@gmail.com> Signed-off-by: David S.
