The enetc driver does not implement .ndo_change_mtu, instead it configures the MAC register field PTC{Traffic Class}MSDUR[MAXSDU] statically to a large value during probe time. The driver used to configure only the max SDU for traffic class 0, and that was fine while the driver could only use traffic class 0. But with the introduction of mqprio, sending a large frame into any other TC than 0 is broken. This patch fixes that by replicating per traffic class the static configuration done in enetc_configure_port_mac().

The 1/10GbaseT modes were set up for cards with SFP+ cages in 3497ed8c ("sfc: report supported link speeds on SFP connections"). 10GbaseT was likely used since no 10G fibre mode existed. The missing fibre modes for 1/10G were added to ethtool.h in 5711a982 ("net: ethtool: add support for 1000BaseX and missing 10G link modes") shortly thereafter. The user guide available at https://support-nic.xilinx.com/wp/drivers lists support for the following cable and transceiver types in section 2.9: - QSFP28 100G Direct Attach Cables - QSFP28 100G SR Optical Transceivers (with SR4 modules listed) - SFP28 25G Direct Attach Cables - SFP28 25G SR Optical Transceivers - QSFP+ 40G Direct Attach Cables - QSFP+ 40G Active Optical Cables - QSFP+ 40G SR4 Optical Transceivers - QSFP+ to SFP+ Breakout Direct Attach Cables - QSFP+ to SFP+ Breakout Active Optical Cables - SFP+ 10G Direct Attach Cables - SFP+ 10G SR Optical Transceivers - SFP+ 10G LR Optical Transceivers - SFP 1000BASE‐T Transceivers - 1G Optical Transceivers (From user guide issue 28. Issue 16 which also includes older cards like SFN5xxx/SFN6xxx has matching lists for 1/10/40G transceiver types.)

Current Work Queue Entry (WQE) checksum (csum) flags in the ethernet segment (eseg) in case of IPsec crypto offload datapath are not aligned with PRM/HW expectations. Currently the driver always sets the l3_inner_csum flag in case of IPsec because of the wrong usage of skb->encapsulation as indicator for inner IPsec header since skb->encapsulation is always ON for IPsec packets since IPsec itself is an encapsulation protocol. The above forced a failing attempts of calculating csum of non-existing segments (like in the IP|ESP|TCP packet case which does not have an l3_inner) which led to lots of packet drops hence the low throughput. Fix by using xo->inner_ipproto as indicator for inner IPsec header instead of skb->encapsulation in addition to setting the csum flags as following: * Tunnel Mode: * Pkt: MAC IP ESP IP L4 * CSUM: l3_cs | l3_inner_cs | l4_inner_cs * * Transport Mode: * Pkt: MAC IP ESP L4 * CSUM: l3_cs [ | l4_cs (checksum partial case)] * * Tunnel(VXLAN TCP/UDP) over Transport Mode * Pkt: MAC IP ESP UDP VXLAN IP L4 * CSUM: l3_cs | l3_inner_cs | l4_inner_cs Fixes: f1267798 ("net/mlx5: Fix checksum issue of VXLAN and IPsec crypto offload") Signed-off-by:

IPsec crypto offload current Software Parser (SWP) fields settings in the ethernet segment (eseg) are not aligned with PRM/HW expectations. Among others in case of IP|ESP|TCP packet, current driver sets the offsets for inner_l3 and inner_l4 although there is no inner l3/l4 headers relative to ESP header in such packets. SWP provides the offsets for HW ,so it can be used to find csum fields to offload the checksum, however these are not necessarily used by HW and are used as fallback in case HW fails to parse the packet, e.g when performing IPSec Transport Aware (IP | ESP | TCP) there is no need to add SW parse on inner packet. So in some cases packets csum was calculated correctly , whereas in other cases it failed. The later faced csum errors (caused by wrong packet length calculations) which led to lots of packet drops hence the low throughput. Fix by setting the SWP fields as expected in a IP|ESP|TCP packet. the following describe the expected SWP offsets: * Tunnel Mode: * SWP: OutL3 InL3 InL4 * Pkt: MAC IP ESP IP L4 * * Transport Mode: * SWP: OutL3 OutL4 * Pkt: MAC IP ESP L4 * * Tunnel(VXLAN TCP/UDP) over Transport Mode * SWP: OutL3 InL3 InL4 * Pkt: MAC IP ESP UDP VXLAN IP L4 Fixes: f1267798 ("net/mlx5: Fix checksum issue of VXLAN and IPsec crypto offload") Signed-off-by:

Both multipath and bonding events are changing the HW LAG state independently.

However, the value of hdev->reset_pending may also be assigned by the interrupt function hclgevf_misc_irq_handle(), which may cause the loop fail to exit and keep occupying the workqueue.

Currently when there is a rx page allocation failure, it is possible that polling may be stopped if there is no more packet to be reveiced, which may cause queue stall problem under memory pressure. This patch makes sure polling is scheduled again when there is any rx page allocation failure, and polling will try to allocate receive buffers until it succeeds. Now the allocation retry is added, it is unnecessary to do the rx page allocation at the end of rx cleaning, so remove it. And reset the unused_count to zero after calling hns3_nic_alloc_rx_buffers() to avoid calling hns3_nic_alloc_rx_buffers() repeatedly under memory pressure.

This reverts commit 09e856d5. When an interface is enslaved in a VRF, prerouting conntrack hook is called twice: once in the context of the original input interface, and once in the context of the VRF interface. If no special precausions are taken, this leads to creation of two conntrack entries instead of one, and breaks SNAT. Commit above was intended to avoid creation of extra conntrack entries when input interface is enslaved in a VRF. It did so by resetting conntrack related data associated with the skb when it enters VRF context. However it breaks netfilter operation. Imagine a use case when conntrack zone must be assigned based on the original input interface, rather than VRF interface (that would make original interfaces indistinguishable). One could create netfilter rules similar to these: chain rawprerouting { type filter hook prerouting priority raw; iif realiface1 ct zone set 1 return iif realiface2 ct zone set 2 return } This works before the mentioned commit, but not after: zone assignment is "forgotten", and any subsequent NAT or filtering that is dependent on the conntrack zone does not work. Here is a reproducer script that demonstrates the difference in behaviour. ========== #!/bin/sh # This script demonstrates unexpected change of nftables behaviour # caused by commit 09e856d5 ""vrf: Reset skb conntrack # connection on VRF rcv" # https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=09e856d54bda5f288ef8437a90ab2b9b3eab83d1 # # Before the commit, it was possible to assign conntrack zone to a # packet (or mark it for `notracking`) in the prerouting chanin, raw # priority, based on the `iif` (interface from which the packet # arrived). # After the change, # if the interface is enslaved in a VRF, such # assignment is lost. Instead, assignment based on the `iif` matching # the VRF master interface is honored. Thus it is impossible to # distinguish packets based on the original interface. # # This script demonstrates this change of behaviour: conntrack zone 1 # or 2 is assigned depending on the match with the original interface # or the vrf master interface. It can be observed that conntrack entry # appears in different zone in the kernel versions before and after # the commit.

When the a large chunk of data send and the receiver does not send a Flow Control frame back in time, the sendmsg() does not return a error code, but the number of bytes sent corresponding to the size of the packet. If a timeout occurs the isotp_tx_timer_handler() is fired, sets sk->sk_err and calls the sk->sk_error_report() function. It was wrongly expected that the error would be propagated to user space in every case. For isotp_sendmsg() blocking on wait_event_interruptible() this is not the case. This patch fixes the problem by checking if sk->sk_err is set and returning the error to user space.

A new warning in clang points out two places in this driver where boolean expressions are being used with a bitwise OR instead of a logical one: drivers/net/ethernet/netronome/nfp/nfp_asm.c:199:20: error: use of bitwise '|' with boolean operands [-Werror,-Wbitwise-instead-of-logical] reg->src_lmextn = swreg_lmextn(lreg) | swreg_lmextn(rreg); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ || drivers/net/ethernet/netronome/nfp/nfp_asm.c:199:20: note: cast one or both operands to int to silence this warning drivers/net/ethernet/netronome/nfp/nfp_asm.c:280:20: error: use of bitwise '|' with boolean operands [-Werror,-Wbitwise-instead-of-logical] reg->src_lmextn = swreg_lmextn(lreg) | swreg_lmextn(rreg); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ || drivers/net/ethernet/netronome/nfp/nfp_asm.c:280:20: note: cast one or both operands to int to silence this warning 2 errors generated. The motivation for the warning is that logical operations short circuit while bitwise operations do not. In this case, it does not seem like short circuiting is harmful so implement the suggested fix of changing to a logical operation to fix the warning.

We currently have some implicit padding in struct sockaddr_mctp. This patch makes this padding explicit, and ensures we have consistent layout on platforms with <32bit alignmnent. Fixes: 60fc6398 ("mctp: Add sockaddr_mctp to uapi") Signed-off-by:

Use the more precise __kernel_sa_family_t for smctp_family, to match struct sockaddr. Also, use an unsigned int for the network member; negative networks don't make much sense. We're already using unsigned for mctp_dev and mctp_skb_cb, but need to change mctp_sock to suit. Fixes: 60fc6398 ("mctp: Add sockaddr_mctp to uapi") Signed-off-by:
