The walk implementation of most qdisc class modules is basically the same. That is, the values of count and skip are checked first. If count is greater than or equal to skip, the registered fn function is executed. Otherwise, increase the value of count. So we can reconstruct them. Signed-off-by:

The 3 functions that want access to the taprio_list: taprio_dev_notifier(), taprio_destroy() and taprio_init() are all called with the rtnl_mutex held, therefore implicitly serialized with respect to each other. A spin lock serves no purpose. Signed-off-by:

Gal Pressman says: ==================== Support 256 bit TLS keys with device offload This series adds support for 256 bit TLS keys with device offload, and a cleanup patch to remove repeating code: - Patches #1-2 add cipher sizes descriptors which allow reducing the amount of code duplications. - Patch #3 allows 256 bit keys to be TX offloaded in the tls module (RX already supported). - Patch #4 adds 256 bit keys support to the mlx5 driver. ==================== Link: https://lore.kernel.org/r/20220920130150.3546-1-gal@nvidia.comSigned-off-by:

Any change to the hardware timestamps configuration triggers nic restart, which breaks transmition and reception of network packets for a while. But there is no need to fully restart the device because while configuring hardware timestamps. The code for changing configuration runs after all of the initialisation, when the NIC is actually up and running. This patch changes the code that ioctl will only update configuration registers and will not trigger carrier status change, but in case of timestamps for all rx packetes it fallbacks to close()/open() sequnce because of synchronization issues in the hardware. Tested on BCM57504. Cc: Richard Cochran <richardcochran@gmail.com> Signed-off-by:

When reading the timestamp is required bnxt_tx_int() hands over the ownership of the completed skb to the PTP worker. The skb should not be used afterwards, as the worker may run before the rest of our code and free the skb, leading to a use-after-free. Since dev_kfree_skb_any() accepts NULL make the loss of ownership more obvious and set skb to NULL. Fixes: 83bb623c ("bnxt_en: Transmit and retrieve packet timestamps") Reviewed-by:

Sean Anderson authored
There is a separate receive path for small packets (under 256 bytes). Instead of allocating a new dma-capable skb to be used for the next packet, this path allocates a skb and copies the data into it (reusing the existing sbk for the next packet). There are two bytes of junk data at the beginning of every packet. I believe these are inserted in order to allow aligned DMA and IP headers. We skip over them using skb_reserve. Before copying over the data, we must use a barrier to ensure we see the whole packet. The current code only synchronizes len bytes, starting from the beginning of the packet, including the junk bytes. However, this leaves off the final two bytes in the packet. Synchronize the whole packet. To reproduce this problem, ping a HME with a payload size between 17 and 214 $ ping -s 17 <hme_address> which will complain rather loudly about the data mismatch. Small packets (below 60 bytes on the wire) do not have this issue. I suspect this is related to the padding added to increase the minimum packet size.

Wen Gu says: ==================== Separate SMC parameter settings from TCP sysctls SMC shares some sysctls with TCP, but considering the difference between these two protocols, it may not be very suitable for SMC to reuse TCP parameter settings in some cases, such as keepalive time or buffer size. So this patch set aims to introduce some SMC specific sysctls to independently and flexibly set the parameters that suit SMC. ==================== Link: https://lore.kernel.org/r/1663667542-119851-1-git-send-email-guwen@linux.alibaba.comSigned-off-by:

Currently, SMC uses smc->sk.sk_{rcv|snd}buf to create buffers for send buffer and RMB. And the values of buffer size are from tcp_{w|r}mem in clcsock. The buffer size from TCP socket doesn't fit SMC well. Generally, buffers are usually larger than TCP for SMC-R/-D to get higher performance, for they are different underlay devices and paths. So this patch unbinds buffer size from TCP, and introduces two sysctl knobs to tune them independently. Also, these knobs are per net namespace and work for containers.

SMC-R tests the viability of link by sending out TEST_LINK LLC messages over RoCE fabric when connections on link have been idle for a time longer than keepalive interval (testlink time). But using tcp_keepalive_time as testlink time maybe not quite suitable because it is default no less than two hours[1], which is too long for single link to find peer dead. The active host will still use peer-dead link (QP) sending messages, and can't find out until get IB_WC_RETRY_EXC_ERR error CQEs, which takes more time than TEST_LINK timeout (SMC_LLC_WAIT_TIME) normally. So this patch introduces a independent sysctl for SMC-R to set link keepalive time, in order to detect link down in time. The default value is 30 seconds.
