2021-06-02Merge branch 'irdma' into rdma.git for-nextJason Gunthorpe
Shiraz Saleem says: ==================== Add Intel Ethernet Protocol Driver for RDMA (irdma) The following patch series introduces a unified Intel Ethernet Protocol Driver for RDMA (irdma) for the X722 iWARP device and a new E810 device which supports iWARP and RoCEv2. The irdma module replaces the legacy i40iw module for X722 and extends the ABI already defined for i40iw. It is backward compatible with legacy X722 rdma-core provider (libi40iw). X722 and E810 are PCI network devices that are RDMA capable. The RDMA block of this parent device is represented via an auxiliary device exported to 'irdma' using the core auxiliary bus infrastructure recently added for 5.11 kernel. The parent PCI netdev drivers 'i40e' and 'ice' register auxiliary RDMA devices with private data/ops encapsulated that bind to auxiliary drivers registered in irdma module. Currently, default is RoCEv2 for E810. Runtime support for protocol switch to iWARP will be made available via devlink in a future patch. ==================== Link: https://lore.kernel.org/r/20210602205138.889-1-shiraz.saleem@intel.com Signed-off-by: Jason Gunthorpe <jgg@nvidia.com> * branch 'irdma': RDMA/irdma: Update MAINTAINERS file RDMA/irdma: Add irdma Kconfig/Makefile and remove i40iw RDMA/irdma: Add ABI definitions RDMA/irdma: Add dynamic tracing for CM RDMA/irdma: Add miscellaneous utility definitions RDMA/irdma: Add user/kernel shared libraries RDMA/irdma: Add RoCEv2 UD OP support RDMA/irdma: Implement device supported verb APIs RDMA/irdma: Add PBLE resource manager RDMA/irdma: Add connection manager RDMA/irdma: Add QoS definitions RDMA/irdma: Add privileged UDA queue implementation RDMA/irdma: Add HMC backing store setup functions RDMA/irdma: Implement HW Admin Queue OPs RDMA/irdma: Implement device initialization definitions RDMA/irdma: Register auxiliary driver and implement private channel OPs i40e: Register auxiliary devices to provide RDMA i40e: Prep i40e header for aux bus conversion ice: Register auxiliary device to provide RDMA ice: Implement iidc operations ice: Initialize RDMA support iidc: Introduce iidc.h i40e: Replace one-element array with flexible-array member

2021-06-02devlink: Allow setting parent node of rate objectsDmytro Linkin
Refactor DEVLINK_CMD_RATE_{GET|SET} command handlers to support setting a node as a parent for another rate object (leaf or node) by means of new attribute DEVLINK_ATTR_RATE_PARENT_NODE_NAME. Extend devlink ops with new callbacks rate_{leaf|node}_parent_set() to set node as a parent for rate object to allow supporting drivers to implement rate grouping through devlink. Driver implementations are allowed to support leafs or node children only. Invoking callback with NULL as parent should be threated by the driver as unset parent action. Extend rate object struct with reference counter to disallow deleting a node with any child pointing to it. User should unset parent for the child explicitly. Example: $ devlink port function rate add netdevsim/netdevsim10/group1 $ devlink port function rate add netdevsim/netdevsim10/group2 $ devlink port function rate set netdevsim/netdevsim10/group1 parent group2 $ devlink port function rate show netdevsim/netdevsim10/group1 netdevsim/netdevsim10/group1: type node parent group2 $ devlink port function rate set netdevsim/netdevsim10/group1 noparent Co-developed-by: Vlad Buslov <vladbu@nvidia.com> Signed-off-by: Vlad Buslov <vladbu@nvidia.com> Signed-off-by: Dmytro Linkin <dlinkin@nvidia.com> Reviewed-by: Jiri Pirko <jiri@nvidia.com> Signed-off-by: David S.

2021-06-02devlink: Introduce rate nodesDmytro Linkin
Implement support for DEVLINK_CMD_RATE_{NEW|DEL} commands that are used to create and delete devlink rate nodes. Add new attribute DEVLINK_ATTR_RATE_NODE_NAME that specify node name string. The node name is an alphanumeric identifier. No valid node name can be a devlink port index, eg. decimal number. Extend devlink ops with new callbacks rate_node_{new|del}() and rate_node_tx_{share|max}_set() to allow supporting drivers to implement ports rate grouping and setting tx rate of rate nodes through devlink. Expose devlink_rate_nodes_destroy() function to allow vendor driver do proper cleanup of internally allocated resources for the nodes if the driver goes down or due to any other reasons which requires nodes to be destroyed. Disallow moving device from switchdev to legacy mode if any node exists on that device. User must explicitly delete nodes before switching mode. Example: $ devlink port function rate add netdevsim/netdevsim10/group1 $ devlink port function rate set netdevsim/netdevsim10/group1 \ tx_share 10mbit tx_max 100mbit Add + set command can be combined: $ devlink port function rate add netdevsim/netdevsim10/group1 \ tx_share 10mbit tx_max 100mbit $ devlink port function rate show netdevsim/netdevsim10/group1 netdevsim/netdevsim10/group1: type node tx_share 10mbit tx_max 100mbit $ devlink port function rate del netdevsim/netdevsim10/group1 Co-developed-by: Vlad Buslov <vladbu@nvidia.com> Signed-off-by: Vlad Buslov <vladbu@nvidia.com> Signed-off-by: Dmytro Linkin <dlinkin@nvidia.com> Reviewed-by: Jiri Pirko <jiri@nvidia.com> Signed-off-by: David S.

Extend devlink ops with new callbacks rate_leaf_tx_{share|max}_set() to allow supporting drivers to implement rate control through devlink. New attributes are optional. Driver implementations are allowed to support either or both of them. Shared rate example: $ devlink port function rate set netdevsim/netdevsim10/0 tx_share 10mbit $ devlink port function rate show netdevsim/netdevsim10/0 netdevsim/netdevsim10/0: type leaf tx_share 10mbit Max rate example: $ devlink port function rate set netdevsim/netdevsim10/0 tx_max 100mbit $ devlink port function rate show netdevsim/netdevsim10/0 netdevsim/netdevsim10/0: type leaf tx_max 100mbit Co-developed-by: Vlad Buslov <vladbu@nvidia.com> Signed-off-by: Vlad Buslov <vladbu@nvidia.com> Signed-off-by: Dmytro Linkin <dlinkin@nvidia.com> Reviewed-by: Jiri Pirko <jiri@nvidia.com> Signed-off-by: David S.

2021-05-28netfilter: nft_exthdr: Support SCTP chunksPhil Sutter
Chunks are SCTP header extensions similar in implementation to IPv6 extension headers or TCP options. Reusing exthdr expression to find and extract field values from them is therefore pretty straightforward. For now, this supports extracting data from chunks at a fixed offset (and length) only - chunks themselves are an extensible data structure; in order to make all fields available, a nested extension search is needed.

2021-05-27can: uapi: introduce CANFD_FDF flag for mixed content in struct canfd_frameOliver Hartkopp
The struct can_frame and struct canfd_frame intentionally share the same layout to be able to write CAN frame content into a CAN FD frame structure. When this is done the former differentiation via CAN_MTU / CANFD_MTU is lost. CANFD_FDF allows programmers to mark CAN FD frames in the case of using struct canfd_frame for mixed CAN/CAN FD content (dual use). N.B. the Kernel APIs do NOT provide mixed CAN / CAN FD content inside of struct canfd_frame therefore the CANFD_FDF flag is disregarded by Linux.

2021-05-26xdp: Extend xdp_redirect_map with broadcast supportHangbin Liu
This patch adds two flags BPF_F_BROADCAST and BPF_F_EXCLUDE_INGRESS to extend xdp_redirect_map for broadcast support. With BPF_F_BROADCAST the packet will be broadcasted to all the interfaces in the map. with BPF_F_EXCLUDE_INGRESS the ingress interface will be excluded when do broadcasting. When getting the devices in dev hash map via dev_map_hash_get_next_key(), there is a possibility that we fall back to the first key when a device was removed. This will duplicate packets on some interfaces. So just walk the whole buckets to avoid this issue. For dev array map, we also walk the whole map to find valid interfaces. Function bpf_clear_redirect_map() was removed in commit ee75aef23afe ("bpf, xdp: Restructure redirect actions"). Add it back as we need to use ri->map again. With test topology: +-------------------+ +-------------------+ | Host A (i40e 10G) | ---------- | eno1(i40e 10G) | +-------------------+ | | | Host B | +-------------------+ | | | Host C (i40e 10G) | ---------- | eno2(i40e 10G) | +-------------------+ | | | +------+ | | veth0 -- | Peer | | | veth1 -- | | | | veth2 -- | NS | | | +------+ | +-------------------+ On Host A: # pktgen/pktgen_sample03_burst_single_flow.sh -i eno1 -d $dst_ip -m $dst_mac -s 64 On Host B(Intel(R) Xeon(R) CPU E5-2690 v3 @ 2.60GHz, 128G Memory): Use xdp_redirect_map and xdp_redirect_map_multi in samples/bpf for testing.

2021-05-21drm/amdgpu: Add new placement for preemptible SG BOsFelix Kuehling
SG BOs such as dmabuf imports and userptr BOs do not consume system resources directly. Instead they point to resources owned elsewhere. They typically get evicted by DMABuf move notifiers of MMU notifiers. If those notifiers don't need to wait for hardware fences (i.e. the SG BOs are used in a preemptible context), then we don't need to limit them to the GTT size and we don't need TTM to evict them. Create a new placement for such preemptible SG BOs that does not impose artificial size limits and TTM evictions.

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace Pull siginfo fix from Eric Biederman: "During the merge window an issue with si_perf and the siginfo ABI came up. The alpha and sparc siginfo structure layout had changed with the addition of SIGTRAP TRAP_PERF and the new field si_perf. The reason only alpha and sparc were affected is that they are the only architectures that use si_trapno. Looking deeper it was discovered that si_trapno is used for only a few select signals on alpha and sparc, and that none of the other _sigfault fields past si_addr are used at all. Which means technically no regression on alpha and sparc. While the alignment concerns might be dismissed the abuse of si_errno by SIGTRAP TRAP_PERF does have the potential to cause regressions in existing userspace. While we still have time before userspace starts using and depending on the new definition siginfo for SIGTRAP TRAP_PERF this set of changes cleans up siginfo_t. - The si_trapno field is demoted from magic alpha and sparc status and made an ordinary union member of the _sigfault member of siginfo_t. Without moving it of course. - si_perf is replaced with si_perf_data and si_perf_type ending the abuse of si_errno. - Unnecessary additions to signalfd_siginfo are removed" * 'for-v5.13-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: signalfd: Remove SIL_PERF_EVENT fields from signalfd_siginfo signal: Deliver all of the siginfo perf data in _perf signal: Factor force_sig_perf out of perf_sigtrap signal: Implement SIL_FAULT_TRAPNO siginfo: Move si_trapno inside the union inside _si_fault
