* net/mlx5e: en_rep: Create uplink rep root table after eswitch offloads tablePaul Blakey2020-03-121-0/+1
| | | | | | | | | | | | | | | | | | The eswitch offloads table, which has the reps (vport) rx miss rules, was moved from OFFLOADS namespace [0,0] (prio, level), to [1,0], so the restore table (the new [0,0]) can come before it. The destinations of these miss rules is the rep root ft (ttc for non uplink reps). Uplink rep root ft is created as OFFLOADS namespace [0,1], and is used as a hook to next RX prio (either ethtool or ttc), but this fails to pass fs_core level's check. Move uplink rep root ft to OFFLOADS prio 1, level 1 ([1,1]), so it will keep the same relative position after the restore table change.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In tunnel and chains setup, we decapsulate the packets on first chain hop, if we miss on later chains, the packet will comes up without tunnel header, so it won't be taken by the tunnel device automatically, which fills the tunnel metadata, and further tc tunnel matches won't work. On miss, we get the tunnel mapping id, which was set on the chain 0 rule that decapsulated the packet. This rule matched the tunnel outer headers. From the tunnel mapping id, we get to this tunnel matches and restore the equivalent tunnel info metadata dst on the skb. We also set the skb->dev to the relevant device (tunnel device). Now further tc processing can be done on the relevant device.

On miss, the packet does not have the outer header and the driver restores the tunnel information from the tunnel id.

| * net/mlx5e: Support inner header rewrite with goto actionPaul Blakey2020-02-193-45/+445
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hardware supports header rewrite of outer headers only. To perform header rewrite on inner headers, we must first decapsulate the packet. Currently, the hardware decap action is explicitly set by the tc tunnel_key unset action. However, with goto action the user won't use the tunnel_key unset action. In addition, header rewrites actions will not apply to the inner header as done by the software model. To support this, we will map each tunnel matches seen on a tc rule to a unique tunnel id, implicity add a decap action on tc chain 0 flows, and mark the packets with this unique tunnel id. Tunnel matches on the decapsulated tunnel on later chains will match on this unique id instead of the actual packet. We will also use this mapping to restore the tunnel info metadata on miss.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, if we miss in hardware after jumping to some chain, we continue in chain 0 in software. This is wrong, and with the new tc skb extension we can now restore the chain id on the skb, so tc can continue with in the correct chain. To restore the chain id in software after a miss in hardware, we create a register mapping from 32bit chain ids to 16bit of reg_c0 (that survives loopback), to 32bit chain ids. We then mark packets that miss on some chain with the current chain id mapping on their reg_c0 field. Using this mapping, we will support up to 64K concurrent chains. This register survives loopback and gets to the CQE on flow_tag via the eswitch restore rules. In next commit, we will reverse the mapping we got on the CQE to a chain id and tell tc to continue in the sw chain where we left off via the tc skb extension.

We add an API so callers can add all the used reg_c0 values (tags) and for each of those we add a restore rule.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Multi chain support requires the miss path to continue the processing from the last chain id, and for that we need to save the chain miss tag (a mapping for 32bit chain id) on reg_c0 which will come in a next patch. Currently reg_c0 is exclusively used to store the source port metadata, giving it 32bit, it is created from 16bits of vcha_id, and 16bits of vport number. We will move this source port metadata to upper 16bits, and leave the lower bits for the chain miss tag. We compress the reg_c0 source port metadata to 16bits by taking 8 bits from vhca_id, and 8bits from the vport number. Since we compress the vport number to 8bits statically, and leave two top ids for special PF/ECPF numbers, we will only support a max of 254 vports with this strategy.

This mapping interface also supports delaying the mapping removal via a workqueue. This is for cases where we need the mapping to have some grace period in regards to finding it back again, for example for packets arriving from hardware that were marked with by a rule with an old mapping that no longer exists.

Set this field in the L3/L4 Filtering test so that it correctly setups the filter instead of returning EOPNOTSUPP.

* | cdc_ncm: Implement the 32-bit version of NCM Transfer BlockAlexander Bersenev2020-03-112-91/+328
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The NCM specification defines two formats of transfer blocks: with 16-bit fields (NTB-16) and with 32-bit fields (NTB-32). Currently only NTB-16 is implemented. This patch adds the support of NTB-32. The motivation behind this is that some devices such as E5785 or E5885 from the current generation of Huawei LTE routers do not support NTB-16. The previous generations of Huawei devices are also use NTB-32 by default. Also this patch enables NTB-32 by default for Huawei devices. During the 2019 ValdikSS made five attempts to contact Huawei to add the NTB-16 support to their router firmware, but they were unsuccessful.
