2021-04-23bpf: Document the pahole release info related to libbpf in bpf_devel_QA.rstTiezhu Yang1-0/+13
pahole starts to use libbpf definitions and APIs since v1.13 after the commit 21507cd3e97b ("pahole: add libbpf as submodule under lib/bpf"). It works well with the git repository because the libbpf submodule will use "git submodule update --init --recursive" to update. Unfortunately, the default github release source code does not contain libbpf submodule source code and this will cause build issues, the tarball from https://git.kernel.org/pub/scm/devel/pahole/pahole.git/ is same with github, you can get the source tarball with corresponding libbpf submodule codes from https://fedorapeople.org/~acme/dwarves This change documents the above issues to give more information so that we can get the tarball from the right place, early discussion is here: https://lore.kernel.org/bpf/2de4aad5-fa9e-1c39-3c92-9bb9229d0966@loongson.cn/ Signed-off-by: Tiezhu Yang <yangtiezhu@loongson.cn> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Reviewed-by: Arnaldo Carvalho de Melo <acme@redhat.com> Link: https://lore.kernel.org/bpf/1619141010-12521-1-git-send-email-yangtiezhu@loongson.cn

2021-04-15ethtool: add FEC statisticsJakub Kicinski2-0/+23
Similarly to pause statistics add stats for FEC. The IEEE standard mandates two sets of counters: - 30.5.1.1.17 aFECCorrectedBlocks - 30.5.1.1.18 aFECUncorrectableBlocks where block is a block of bits FEC operates on. Each of these counters is defined per lane (PCS instance). Multiple vendors provide number of corrected _bits_ rather than/as well as blocks. This set adds the 2 standard-based block counters and a extra one for corrected bits. Counters are exposed to user space via netlink in new attributes. Each attribute carries an array of u64s, first element is the total count, and the following ones are a per-lane break down. Much like with pause stats the operation will not fail when driver does not implement the get_fec_stats callback (nor can the driver fail the operation by returning an error). If stats can't be reported the relevant attributes will be empty. Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2021-04-14net/mlx5: E-Switch, let user to enable disable metadataParav Pandit1-0/+34
Currently each packet inserted in eswitch is tagged with a internal metadata to indicate source vport. Metadata tagging is not always needed. Metadata insertion is needed for multi-port RoCE, failover between representors and stacked devices. In many other cases, metadata enablement is not needed. Metadata insertion slows down the packet processing rate of the E-switch when it is in switchdev mode. Below table show performance gain with metadata disabled for VXLAN offload rules in both SMFS and DMFS steering mode on ConnectX-5 device. ---------------------------------------------- | steering | metadata | pkt size | rx pps | | mode | | | (million) | ---------------------------------------------- | smfs | disabled | 128Bytes | 42 | ---------------------------------------------- | smfs | enabled | 128Bytes | 36 | ---------------------------------------------- | dmfs | disabled | 128Bytes | 42 | ---------------------------------------------- | dmfs | enabled | 128Bytes | 36 | ---------------------------------------------- Hence, allow user to disable metadata using driver specific devlink parameter. Metadata setting of the eswitch is applicable only for the switchdev mode. Example to show and disable metadata before changing eswitch mode: $ devlink dev param show pci/0000:06:00.0 name esw_port_metadata pci/0000:06:00.0: name esw_port_metadata type driver-specific values: cmode runtime value true $ devlink dev param set pci/0000:06:00.0 \ name esw_port_metadata value false cmode runtime $ devlink dev eswitch set pci/0000:06:00.0 mode switchdev Signed-off-by: Parav Pandit <parav@nvidia.com> Reviewed-by: Roi Dayan <roid@nvidia.com> Reviewed-by: Vu Pham <vuhuong@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com> --- changelog: v1->v2: - added performance numbers in commit log - updated commit log and documentation for switchdev mode - added explicit note on when user can disable metadata in documentation

Define get_module_eeprom_by_page() ethtool callback and implement netlink infrastructure. get_module_eeprom_by_page() allows network drivers to dump a part of module's EEPROM specified by page and bank numbers along with offset and length. It is effectively a netlink replacement for get_module_info() and get_module_eeprom() pair, which is needed due to emergence of complex non-linear EEPROM layouts.

2021-04-05net: x25: Queue received packets in the drivers instead of per-CPU queuesXie He1-56/+9
X.25 Layer 3 (the Packet Layer) expects layer 2 to provide a reliable datalink service such that no packets are reordered or dropped. And X.25 Layer 2 (the LAPB layer) is indeed designed to provide such service. However, this reliability is not preserved when a driver calls "netif_rx" to deliver the received packets to layer 3, because "netif_rx" will put the packets into per-CPU queues before they are delivered to layer 3. If there are multiple CPUs, the order of the packets may not be preserved. The per-CPU queues may also drop packets if there are too many. Therefore, we should not call "netif_rx" to let it queue the packets. Instead, we should use our own queue that won't reorder or drop packets. This patch changes all X.25 drivers to use their own queues instead of calling "netif_rx". The patch also documents this requirement in the "x25-iface" documentation.

2021-04-04PCI/IOV: Add sysfs MSI-X vector assignment interfaceLeon Romanovsky1-0/+29
A typical cloud provider SR-IOV use case is to create many VFs for use by guest VMs. The VFs may not be assigned to a VM until a customer requests a VM of a certain size, e.g., number of CPUs. A VF may need MSI-X vectors proportional to the number of CPUs in the VM, but there is no standard way to change the number of MSI-X vectors supported by a VF. Some Mellanox ConnectX devices support dynamic assignment of MSI-X vectors to SR-IOV VFs. This can be done by the PF driver after VFs are enabled, and it can be done without affecting VFs that are already in use. The hardware supports a limited pool of MSI-X vectors that can be assigned to the PF or to individual VFs. This is device-specific behavior that requires support in the PF driver. Add a read-only "sriov_vf_total_msix" sysfs file for the PF and a writable "sriov_vf_msix_count" file for each VF. Management software may use these to learn how many MSI-X vectors are available and to dynamically assign them to VFs before the VFs are passed through to a VM. If the PF driver implements the ->sriov_get_vf_total_msix() callback, "sriov_vf_total_msix" contains the total number of MSI-X vectors available for distribution among VFs. If no driver is bound to the VF, writing "N" to "sriov_vf_msix_count" uses the PF driver ->sriov_set_msix_vec_count() callback to assign "N" MSI-X vectors to the VF. When a VF driver subsequently reads the MSI-X Message Control register, it will see the new Table Size "N".

2021-04-01net: document a side effect of ip_local_reserved_portsOtto Hollmann1-1/+3
If there is overlapp between ip_local_port_range and ip_local_reserved_ports with a huge reserved block, it will affect probability of selecting ephemeral ports, see file net/ipv4/inet_hashtables.c:723 int __inet_hash_connect( ... for (i = 0; i < remaining; i += 2, port += 2) { if (unlikely(port >= high)) port -= remaining; if (inet_is_local_reserved_port(net, port)) continue; E.g. if there is reserved block of 10000 ports, two ports right after this block will be 5000 more likely selected than others. If this was intended, we can/should add note into documentation as proposed in this commit, otherwise we should think about different solution. One option could be mapping table of continuous port ranges. Second option could be letting user to modify step (port+=2) in above loop, e.g. using new sysctl parameter.

2021-03-31ethtool: support FEC settings over netlinkJakub Kicinski1-2/+60
Add FEC API to netlink. This is not a 1-to-1 conversion. FEC settings already depend on link modes to tell user which modes are supported. Take this further an use link modes for manual configuration. Old struct ethtool_fecparam is still used to talk to the drivers, so we need to translate back and forth. We can revisit the internal API if number of FEC encodings starts to grow. Enforce only one active FEC bit (by using a bit position rather than another mask).
