2021-10-28octeontx2-af: Display all enabled PF VF rsrc_alloc entries.Rakesh Babu1-32/+106
Currently, we are using a fixed buffer size of length 2048 to display rsrc_alloc output. As a result a maximum of 2048 characters of rsrc_alloc output is displayed, which may lead sometimes to display only partial output. This patch fixes this dependency on max limit of buffer size and displays all PF VF entries. Each column of the debugfs entry "rsrc_alloc" uses a fixed width of 12 characters to print the list of LFs of each block for a PF/VF. If the length of list of LFs of a block exceeds this fixed width then the list gets truncated and displays only a part of the list. This patch fixes this by using the maximum possible length of list of LFs among all blocks of all PFs and VFs entries as the width size. Fixes: f7884097141b ("octeontx2-af: Formatting debugfs entry rsrc_alloc.")

However, an eBPF program doesn't always need to access the whole packet data. The maximum direct packet access (DPA) offset has always been caculated by verifier and stored in the max_pkt_offset field of prog aux data.

Currently, the workqueue of hclge/hclgevf is executed on the CPU that initiates scheduling requests by default. In stress scenarios, the CPU may be busy and workqueue scheduling is completed after a long period of time. To avoid this situation and implement proper scheduling, use the WQ_UNBOUND mode instead. In this way, the workqueue can be performed on a relatively idle CPU. Signed-off-by: Yufeng Mo <moyufeng@huawei.com> Signed-off-by: Guangbin Huang <huangguangbin2@huawei.com> Signed-off-by: David S.

2021-10-27net: hns3: fix pause config problem after autoneg disabledGuangbin Huang5-10/+57
If a TP port is configured by follow steps: 1.ethtool -s ethx autoneg off speed 100 duplex full 2.ethtool -A ethx rx on tx on 3.ethtool -s ethx autoneg on(rx&tx negotiated pause results are off) 4.ethtool -s ethx autoneg off speed 100 duplex full In step 3, driver will set rx&tx pause parameters of hardware to off as pause parameters negotiated with link partner are off. After step 4, the "ethtool -a ethx" command shows both rx and tx pause parameters are on. However, pause parameters of hardware are still off and port has no flow control function actually. To fix this problem, if autoneg is disabled, driver uses its saved parameters to restore pause of hardware. If the speed is not changed in this case, there is no link state changed for phy, it will cause the pause parameter is not taken effect, so we need to force phy to go down and up.

2021-10-27nvme-tcp: fix possible req->offset corruptionVarun Prakash1-1/+2
With commit db5ad6b7f8cd ("nvme-tcp: try to send request in queue_rq context") r2t and response PDU can get processed while send function is executing. Current data digest send code uses req->offset after kernel_sendmsg(), this creates a race condition where req->offset gets reset before it is used in send function. This can happen in two cases - 1. Target sends r2t PDU which resets req->offset. 2. Target send response PDU which completes the req and then req is used for a new command, nvme_tcp_setup_cmd_pdu() resets req->offset. Fix this by storing req->offset in a local variable and using this local variable after kernel_sendmsg().
