cp_hashinfo.ehash_mask is always an odd number, which is set in function alloc_large_system_hash(). See bellow, if (_hash_mask) *_hash_mask = (1 << log2qty) - 1; <<< always odd number Hence the local variable 'cnt' is a even number, as a result of that it is no difference to do the incrementation here.

In the loop of mvneta_tx_done_gbe(), we call the smp_processor_id() each time, move the call out of the loop to optimize the code a bit. Before the patch, the loop looks like(under arm64): ldr x1, [x29,#120] ... ldr w24, [x1,#36] ... bl 0 <_raw_spin_lock> str w24, [x27,#132] ... After the patch, the loop looks like(under arm64): ... bl 0 <_raw_spin_lock> str w23, [x28,#132] ... where w23 is loaded so be ready before the loop. >From another side, mvneta_tx_done_gbe() is called from mvneta_poll() which is in non-preemptible context, so it's safe to call the smp_processor_id() function once.

tokens and ctokens are defined as s64 in htb_class structure, and clamped to 32bits value during netlink dumps: cl->xstats.tokens = clamp_t(s64, PSCHED_NS2TICKS(cl->tokens), INT_MIN, INT_MAX); Defining it as u32 is working since userspace (tc) is printing it as signed int, but a correct definition from the beginning is probably better.

Added test case to receive multiple records with a single recvmsg() operation with a MSG_PEEK set. Signed-off-by: NDavid S. Miller <davem@davemloft.net>
-
由 Vakul Garg 提交于
When tls records are decrypted using asynchronous acclerators such as NXP CAAM engine, the crypto apis return -EINPROGRESS. Presently, on getting -EINPROGRESS, the tls record processing stops till the time the crypto accelerator finishes off and returns the result. This incurs a context switch and is not an efficient way of accessing the crypto accelerators. Crypto accelerators work efficient when they are queued with multiple crypto jobs without having to wait for the previous ones to complete. The patch submits multiple crypto requests without having to wait for for previous ones to complete. This has been implemented for records which are decrypted in zero-copy mode. At the end of recvmsg(), we wait for all the asynchronous decryption requests to complete. The references to records which have been sent for async decryption are dropped. For cases where record decryption is not possible in zero-copy mode, asynchronous decryption is not used and we wait for decryption crypto api to complete. For crypto requests executing in async fashion, the memory for aead_request, sglists and skb etc is freed from the decryption completion handler. The decryption completion handler wakesup the sleeping user context when recvmsg() flags that it has done sending all the decryption requests and there are no more decryption requests pending to be completed.

Currently a Linux IPv6 TCP sender will change the flow label upon timeouts to potentially steer away from a data path that has gone bad. However this does not help if the problem is on the ACK path and the data path is healthy. In this case the receiver is likely to receive repeated spurious retransmission because the sender couldn't get the ACKs in time and has recurring timeouts. This patch adds another feature to mitigate this problem. It leverages the DSACK states in the receiver to change the flow label of the ACKs to speculatively re-route the ACK packets. In order to allow triggering on the second consecutive spurious RTO, the receiver changes the flow label upon sending a second consecutive DSACK for a sequence number below RCV.NXT.

This commit gets rid of the structure xdp_umem_props. It was there to be able to break a dependency at one point, but this is no longer needed. The values in the struct are instead stored directly in the xdp_umem structure. This simplifies the xsk code as well as af_xdp zero-copy drivers and as a bonus gets rid of one internal header file.

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2018-08-30 This series contains updates to i40e, i40evf and virtchnl. Jake implements helper functions to use an array to handle the queue stats which reduces the boiler plate code as well as keep the complexity localized to a few functions. Paweł adds the ability to change a VF's MAC address from the host side without having to reload the VF driver on the guest side. Paul adds a check to ensure that the number of queues that the PF sends to the VF is equal to or less than the maximum number of queues the VF can support. Mitch fixes an issue caught by GCC 8, where we need to not include the terminating null in the length of the string for strncpy(). Lihong fixes a VF issue to ensure that it does not enter into promiscuous mode when macvlan is added to the VF. Fixed a potential crash after a VF is removed, since the workqueue sync for the adminq task was not being cancelled. Harshitha fixes the type for field_flags in the virtchnl_filter struct. Martyna removes an unnecessary check in a conditional if statement. Björn fixes an issue reported by Jesper Dangaard Brouer, where the driver was reporting incorrect statistics when XDP was enabled. Jan fixes the potential reporting of incorrect speed settings. Patryk fixed an issue where the flag I40EVF_FLAG_AQ_ENABLE_VLAN_STRIPPING was getting set when any offload is set via ethtool. Resolved by only setting this flag when VLAN offload is enabled. Also ensure we hold the rtnl lock when we are clearing the interrupt scheme. Added a check when deleting the MAC address from the VF to ensure that the MAC address was not set by the PF and if it was, do not delete it. v2: updated patch 2 in the series based on community feedback from David Miller to inline a function ==================== Signed-off-by: NDavid S.
