2020-08-25chelsio: switch from 'pci_' to 'dma_' APIChristophe JAILLET2-35/+39
The wrappers in include/linux/pci-dma-compat.h should go away. The patch has been generated with the coccinelle script below and has been hand modified to replace GFP_ with a correct flag. It has been compile tested. When memory is allocated in 'free_rx_resources()' and 'alloc_tx_resources()' (sge.c) GFP_KERNEL can be used because it is already used in these functions. Moreover, they can only be called from a .ndo_open function. So it is guarded by the 'rtnl_lock()', which is a mutex. While at it, a pr_err message in 'init_one()' has been updated accordingly (s/consistent/coherent). @@ @@ - PCI_DMA_BIDIRECTIONAL + DMA_BIDIRECTIONAL @@ @@ - PCI_DMA_TODEVICE + DMA_TO_DEVICE @@ @@ - PCI_DMA_FROMDEVICE + DMA_FROM_DEVICE @@ @@ - PCI_DMA_NONE + DMA_NONE @@ expression e1, e2, e3; @@ - pci_alloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3; @@ - pci_zalloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3, e4; @@ - pci_free_consistent(e1, e2, e3, e4) + dma_free_coherent(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_single(e1, e2, e3, e4) + dma_map_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_single(e1, e2, e3, e4) + dma_unmap_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4, e5; @@ - pci_map_page(e1, e2, e3, e4, e5) + dma_map_page(&e1->dev, e2, e3, e4, e5) @@ expression e1, e2, e3, e4; @@ - pci_unmap_page(e1, e2, e3, e4) + dma_unmap_page(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_sg(e1, e2, e3, e4) + dma_map_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_sg(e1, e2, e3, e4) + dma_unmap_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_cpu(e1, e2, e3, e4) + dma_sync_single_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_device(e1, e2, e3, e4) + dma_sync_single_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_cpu(e1, e2, e3, e4) + dma_sync_sg_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_device(e1, e2, e3, e4) + dma_sync_sg_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2; @@ - pci_dma_mapping_error(e1, e2) + dma_mapping_error(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_dma_mask(e1, e2) + dma_set_mask(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_consistent_dma_mask(e1, e2) + dma_set_coherent_mask(&e1->dev, e2) Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: David S.

commit c8729cac2a11 ("cxgb4: add ethtool n-tuple filter insertion") has removed checking control key for determining IP address types for TC-FLOWER rules, which causes all the rules being inserted to hardware to become IPv6 rule type always. So, add back the check to select the correct IP address type to extract and hence fix the correct rule type being inserted to hardware. Also, ethtool_rx_flow_key doesn't have any control key and instead directly sets the IPv4/IPv6 address keys. So, explicitly set the IP address type for ethtool n-tuple filters to reuse the same code.

The UDP reuseport conflict was a little bit tricky. The net-next code, via bpf-next, extracted the reuseport handling into a helper so that the BPF sk lookup code could invoke it. At the same time, the logic for reuseport handling of unconnected sockets changed via commit efc6b6f6c3113e8b203b9debfb72d81e0f3dcace which changed the logic to carry on the reuseport result into the rest of the lookup loop if we do not return immediately. This requires moving the reuseport_has_conns() logic into the callers. While we are here, get rid of inline directives as they do not belong in foo.c files. The other changes were cases of more straightforward overlapping modifications. Signed-off-by: David S. Miller <davem@davemloft.net>
2020-07-23cxgb4: add loopback ethtool self-testVishal Kulkarni3-1/+166
In this test, loopback pkt is created and sent on default queue. The packet goes until the Multi Port Switch (MPS) just before the MAC and based on the specified channel number, it either goes outside the wire on one of the physical ports or looped back to Rx path by MPS. In this case, we're specifying loopback channel, instead of physical ports, so the packet gets looped back to Rx path, instead of getting transmitted on the wire. v3: - Modify commit message to include test details. v2: - Add only loopback self-test.

2020-06-24cxgb4: fix endian conversions for L4 ports in filtersRahul Lakkireddy3-25/+22
The source and destination L4 ports in filter offload need to be in CPU endian. They will finally be converted to Big Endian after all operations are done and before giving them to hardware. The L4 ports for NAT are expected to be passed as a byte stream TCB. So, treat them as such. Fixes following sparse warnings in several places: cxgb4_tc_flower.c:159:33: warning: cast from restricted __be16 cxgb4_tc_flower.c:159:33: warning: incorrect type in argument 1 (different base types) cxgb4_tc_flower.c:159:33: expected unsigned short [usertype] val cxgb4_tc_flower.c:159:33: got restricted __be16 [usertype] dst Fixes: dca4faeb812f ("cxgb4: Add LE hash collision bug fix path in LLD driver") Fixes: 62488e4b53ae ("cxgb4: add basic tc flower offload support") Fixes: 557ccbf9dfa8 ("cxgb4: add tc flower support for L3/L4 rewrite") Signed-off-by: Rahul Lakkireddy <rahul.lakkireddy@chelsio.com> Signed-off-by: David S.

2020-06-24cxgb4: parse TC-U32 key values and masks nativelyRahul Lakkireddy2-49/+91
TC-U32 passes all keys values and masks in __be32 format. The parser already expects this and hence pass the value and masks in __be32 natively to the parser.
