When the action of an xdp program was XDP_TX, lan966x was creating a xdp_frame and use this one to send the frame back. But it is also possible to send back the frame without needing a xdp_frame, because it is possible to send it back using the page. And then once the frame is transmitted is possible to use directly page_pool_recycle_direct as lan966x is using page pools. This would save some CPU usage on this path, which results in higher number of transmitted frames. Bellow are the statistics: Frame size: Improvement: 64 ~8% 256 ~11% 512 ~8% 1000 ~0% 1500 ~0% Signed-off-by:

Gerhard Engleder says: ==================== tsnep: XDP socket zero-copy support Implement XDP socket zero-copy support for tsnep driver. I tried to follow existing drivers like igc as far as possible. But one main difference is that tsnep does not need any reconfiguration for XDP BPF program setup. So I decided to keep this behavior no matter if a XSK pool is used or not. As a result, tsnep starts using the XSK pool even if no XDP BPF program is available. Another difference is that I tried to prevent potentially failing allocations during XSK pool setup. E.g. both memory models for page pool and XSK pool are registered all the time. Thus, XSK pool setup cannot end up with not working queues. Some prework is done to reduce the last two XSK commits to actual XSK changes. ==================== Link: https://lore.kernel.org/r/20230421194656.48063-1-gerhard@engleder-embedded.com Signed-off-by:

Add support for XSK zero-copy to RX path. The setup of the XSK pool can be done at runtime. If the netdev is running, then the queue must be disabled and enabled during reconfiguration. This can be done easily with functions introduced in previous commits. A more important property is that, if the netdev is running, then the setup of the XSK pool shall not stop the netdev in case of errors. A broken netdev after a failed XSK pool setup is bad behavior. Therefore, the allocation and setup of resources during XSK pool setup is done only before any queue is disabled. Additionally, freeing and later allocation of resources is eliminated in some cases. Page pool entries are kept for later use. Two memory models are registered in parallel. As a result, the XSK pool setup cannot fail during queue reconfiguration. In contrast to other drivers, XSK pool setup and XDP BPF program setup are separate actions. XSK pool setup can be done without any XDP BPF program. The XDP BPF program can be added, removed or changed without any reconfiguration of the XSK pool. Test results with A53 1.2GHz: xdpsock rxdrop copy mode, 64 byte frames: pps pkts 1.00 rx 856,054 10,625,775 Two CPUs with both 100% utilization. xdpsock rxdrop zero-copy mode, 64 byte frames: pps pkts 1.00 rx 889,388 4,615,284 Two CPUs with 100% and 20% utilization. Packet rate increases and CPU utilization is reduced. 100% CPU load seems to the base load. This load is consumed by ksoftirqd just for dropping the generated packets without xdpsock running. Using batch API reduced CPU utilization slightly, but measurements are not stable enough to provide meaningful numbers. Signed-off-by: -

SET_COALESCE may change operation mode and parameters in one call. Changing operation mode may cause the driver to reset the parameter values to what is a reasonable default for new operation mode. Since driver does not know which parameters come from user and which are echoed back from ->get, driver may ignore the parameters when switching operation modes. This used to be inevitable for ioctl() but in netlink we know which parameters are actually specified by the user. We could inform which parameters were set by the user but this would lead to a lot of code duplication in the drivers. Instead try to call the drivers twice if both mode and params are changed. The set method already checks if any params need updating so in case the driver did the right thing the first time around - there will be no second call to it's ->set method (only an extra call to ->get()). For mlx5 for example before this patch we'd see: # ethtool -C eth0 adaptive-rx on adaptive-tx on # ethtool -C eth0 adaptive-rx off adaptive-tx off \ tx-usecs 123 rx-usecs 123 Adaptive RX: off TX: off rx-usecs: 3 rx-frames: 32 tx-usecs: 16 tx-frames: 32 [...] After the change: # ethtool -C eth0 adaptive-rx on adaptive-tx on # ethtool -C eth0 adaptive-rx off adaptive-tx off \ tx-usecs 123 rx-usecs 123 Adaptive RX: off TX: off rx-usecs: 123 rx-frames: 32 tx-usecs: 123 tx-frames: 32 [...] This only works for netlink, so it's a small discrepancy between netlink and ioctl(). Since we anticipate most users to move to netlink I believe it's worth making their lives easier. Link: https://lore.kernel.org/r/20230420233302.944382-1-kuba@kernel.org Signed-off-by:

iter_pass_iter_ptr_to_subprog subtest is relying on actual array size being passed as subprog parameter. This combined with recent fixes to precision tracking in conditional jumps ([0]) is now causing verifier to backtrack all the way to the point where sum() and fill() subprogs are called, at which point precision backtrack bails out and forces all the states to have precise SCALAR registers. This in turn causes each possible value of i within fill() and sum() subprogs to cause a different non-equivalent state, preventing iterator code to converge. For now, change the test to assume fixed size of passed in array. Once BPF verifier supports precision tracking across subprogram calls, these changes will be reverted as unnecessary.

Pablo Neira Ayuso says: ==================== Netfilter/IPVS updates for net-next 1) Reduce jumpstack footprint: Stash chain in last rule marker in blob for tracing. Remove last rule and chain from jumpstack. From Florian Westphal. 2) nf_tables validates all tables before committing the new rules. Unfortunately, this has two drawbacks: - Since addition of the transaction mutex pernet state gets written to outside of the locked section from the cleanup callback, this is wrong so do this cleanup directly after table has passed all checks. - Revalidate tables that saw no changes. This can be avoided by keeping the validation state per table, not per netns. From Florian Westphal. 3) Get rid of a few redundant pointers in the traceinfo structure. The three removed pointers are used in the expression evaluation loop, so gcc keeps them in registers. Passing them to the (inlined) helpers thus doesn't increase nft_do_chain text size, while stack is reduced by another 24 bytes on 64bit arches. From Florian Westphal. 4) IPVS cleanups in several ways without implementing any functional changes, aside from removing some debugging output: - Update width of source for ip_vs_sync_conn_options The operation is safe, use an annotation to describe it properly. - Consistently use array_size() in ip_vs_conn_init() It seems better to use helpers consistently. - Remove {Enter,Leave}Function.

As reported by Kumar in [0], the shared ownership implementation for BPF programs has some race conditions which need to be addressed before it can safely be used. This patch does so in a minimal way instead of ripping out shared ownership entirely, as proper fixes for the issues raised will follow ASAP, at which point this patch's commit can be reverted to re-enable shared ownership. The patch removes the ability to call bpf_refcount_acquire_impl from BPF programs. Programs can only bump refcount and obtain a new owning reference using this kfunc, so removing the ability to call it effectively disables shared ownership. Instead of changing success / failure expectations for bpf_refcount-related selftests, this patch just disables them from running for now.

This enables flow control before checking for bootloader signature and deciding whether FW download is needed or not. In case of V1 bootloader chips w8987 and w8997, it is observed that if WLAN FW is downloaded first and power save is enabled in wlan core, bootloader signatures are not emitted by the BT core when the chip is put to sleep. As a result, the driver skips FW download and subsequent HCI commands get timeout errors in dmesg as shown below: [ 112.898867] Bluetooth: hci0: Opcode 0x c03 failed: -110 [ 114.914865] Bluetooth: hci0: Setting baudrate failed (-110) [ 116.930856] Bluetooth: hci0: Setting wake-up method failed (-110) By enabling the flow control, the host enables its RTS pin, and an interrupt in chip's UART peripheral causes the bootloader to wake up, enabling the bootloader signatures, which then helps in downloading the bluetooth FW file.
