This patch adds support for encoding indexed-array attributes with sub-type nest in pyynl. Signed-off-by: Asbjørn Sloth Tønnesen <[email protected]> Signed-off-by: NipaLocal <nipa@local>
This patch add support for decoding hex input, so
that binary attributes can be read through --json.
Example (using future wireguard.yaml):
$ sudo ./tools/net/ynl/pyynl/cli.py --family wireguard \
--do set-device --json '{"ifindex":3,
"private-key":"2a ae 6c 35 c9 4f cf <... to 32 bytes>"}'

The attribute WGALLOWEDIP_A_IPADDR can contain either an IPv4 or an IPv6 address depending on WGALLOWEDIP_A_FAMILY, however in practice it is enough to look at the attribute length. This patch implements an ipv4-or-v6 display hint, that can deal with this kind of attribute. It only implements this display hint for genetlink-legacy, it can be added to other protocol variants if needed, but we don't want to encourage it's use.

Doing the call to dma_sync_single_for_cpu() earlier will allow us to adjust headlen based on the actual size of the protocol headers. Doing this earlier means that we don't need to call mlx5e_copy_skb_header() anymore and rather can call skb_copy_to_linear_data() directly.

mlx5e_skb_from_cqe_mpwrq_nonlinear() copies MLX5E_RX_MAX_HEAD (256) bytes from the page-pool to the skb's linear part. Those 256 bytes include part of the payload. When attempting to do GRO in skb_gro_receive, if headlen > data_offset (and skb->head_frag is not set), we end up aggregating packets in the frag_list. This is of course not good when we are CPU-limited. Also causes a worse skb->len/truesize ratio,... So, let's avoid copying parts of the payload to the linear part. We use eth_get_headlen() to parse the headers and compute the length of the protocol headers, which will be used to copy the relevant bits ot the skb's linear part. We still allocate MLX5E_RX_MAX_HEAD for the skb so that if the networking stack needs to call pskb_may_pull() later on, we don't need to reallocate memory. This gives a nice throughput increase (ARM Neoverse-V2 with CX-7 NIC and LRO enabled): BEFORE: ======= (netserver pinned to core receiving interrupts) $ netperf -H 10.221.81.118 -T 80,9 -P 0 -l 60 -- -m 256K -M 256K 87380 16384 262144 60.01 32547.82 (netserver pinned to adjacent core receiving interrupts) $ netperf -H 10.221.81.118 -T 80,10 -P 0 -l 60 -- -m 256K -M 256K 87380 16384 262144 60.00 52531.67 AFTER: ====== (netserver pinned to core receiving interrupts) $ netperf -H 10.221.81.118 -T 80,9 -P 0 -l 60 -- -m 256K -M 256K 87380 16384 262144 60.00 52896.06 (netserver pinned to adjacent core receiving interrupts) $ netperf -H 10.221.81.118 -T 80,10 -P 0 -l 60 -- -m 256K -M 256K 87380 16384 262144 60.00 85094.90 Additional tests across a larger range of parameters w/ and w/o LRO, w/ and w/o IPv6-encapsulation, different MTUs (1500, 4096, 9000), different TCP read/write-sizes as well as UDP benchmarks, all have shown equal or better performance with this patch.

…_event() A patch similar to 83b09a1("sfc: farch: fix TX queue lookup in TX event handling"). The code was using ef4_channel_get_tx_queue() function with a TXQ label parameter, when it should have been using direct queue access via channel->tx_queue. This mismatch could result in NULL pointer returns, leading to system crashes. Signed-off-by: Chen Yufeng <[email protected]> Signed-off-by: NipaLocal <nipa@local>
For some PTP devices, they have the capability to loop back the periodic output signal for debugging, such as the ptp_qoriq device. So add the generic interfaces to set the periodic output signal loopback, rather than each vendor having a different implementation. Show how many channels support the periodic output signal loopback: $ cat /sys/kernel/debug/ptp<N>/n_perout_loopback Enable the loopback of the periodic output signal of channel X: $ echo <X> 1 > /sys/kernel/debug/ptp<N>/perout_loopback Disable the loopback of the periodic output signal of channel X: $ echo <X> 0 > /sys/kernel/debug/ptp<N>/perout_loopback Suggested-by: Andrew Lunn <[email protected]> Signed-off-by: Wei Fang <[email protected]> Signed-off-by: NipaLocal <nipa@local>
The NETC Timer supports looping back the output pulse signal of Fiper-n into Trigger-n input, so that users can leverage this feature to validate some other features without external hardware support. For example, users can use it to test external trigger stamp (EXTTS). And users can combine EXTTS with loopback mode to check whether the generation time of PPS is aligned with an integral second of PHC, or the periodic output signal (PTP_CLK_REQ_PEROUT) whether is generated at the specified time. Since ptp_clock_info::perout_loopback() has been added to the ptp_clock driver as a generic interface to enable or disable the periodic output signal loopback, therefore, netc_timer_perout_loopback() is added as a callback of ptp_clock_info::perout_loopback(). Test the generation time of PPS event: $ echo 0 1 > /sys/kernel/debug/ptp0/perout_loopback $ echo 1 > /sys/class/ptp/ptp0/pps_enable $ testptp -d /dev/ptp0 -e 3 external time stamp request okay event index 0 at 63.000000017 event index 0 at 64.000000017 event index 0 at 65.000000017 Test the generation time of the periodic output signal: $ echo 0 1 > /sys/kernel/debug/ptp0/perout_loopback $ echo 0 150 0 1 500000000 > /sys/class/ptp/ptp0/period $ testptp -d /dev/ptp0 -e 3 external time stamp request okay event index 0 at 150.000000014 event index 0 at 151.500000015 event index 0 at 153.000000014 Signed-off-by: Wei Fang <[email protected]> Reviewed-by: Vladimir Oltean <[email protected]> Signed-off-by: NipaLocal <nipa@local>

There are currently no kernel tests that verify setting and getting options of the team driver. In the future, options may be added that implicitly change other options, which will make it useful to have tests like these that show nothing breaks. There will be a follow up patch to this that adds new "rx_enabled" and "tx_enabled" options, which will implicitly affect the "enabled" option value and vice versa. The tests use teamnl to first set options to specific values and then gets them to compare to the set values. Signed-off-by: Marc Harvey <[email protected]> Signed-off-by: NipaLocal <nipa@local>
netdev_WARN() uses WARN/WARN_ON to print a backtrace along with file and line information. In this case, udp_tunnel_nic_register() returning an error is just a failed operation, not a kernel bug. A simple warning message is sufficient, so use netdev_warn() instead of netdev_WARN(). The netdev_WARN use was a typo/misuse.
