2021-06-02Merge branch 'irdma' into rdma.git for-nextJason Gunthorpe5-111/+223
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
2021-06-02RDMA/irdma: Add irdma Kconfig/Makefile and remove i40iwShiraz Saleem2-110/+0
Add Kconfig and Makefile to build irdma driver. Remove i40iw driver and add an alias in irdma. Remove legacy exported symbols i40e_register_client and i40e_unregister_client from i40e as they are no longer used. irdma is the replacement driver that supports X722.

2021-06-02devlink: Allow setting parent node of rate objectsDmytro Linkin2-1/+14
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 Linkin2-1/+16
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.

When CONFIG_SMP is not set, the base section is .data and that is not currently handled in any linker script. Add .data..decrypted to PERCPU_DECRYPTED_SECTION, which is included in PERCPU_INPUT -> PERCPU_SECTION, which is include in the x86 linker script when either CONFIG_X86_64 or CONFIG_SMP is unset, taking care of the warning.

If we haven't done a unbind target call we can race where iscsi_conn_teardown wakes up the EH thread and then frees the conn while those threads are still accessing the conn ehwait. We can only do one TMF per session so this just moves the TMF fields from the conn to the session. We can then rely on the iscsi_session_teardown->iscsi_remove_session->__iscsi_unbind_session call to remove the target and it's devices, and know after that point there is no device or scsi-ml callout trying to access the session.

2021-06-02scsi: iscsi: Add iscsi_cls_conn refcount helpersMike Christie1-0/+2
There are a couple places where we could free the iscsi_cls_conn while it's still in use. This adds some helpers to get/put a refcount on the struct and converts an exiting user. Subsequent commits will then use the helpers to fix 2 bugs in the eh code.

2021-06-02scsi: iscsi: Fix in-kernel conn failure handlingMike Christie1-1/+9
Commit 0ab710458da1 ("scsi: iscsi: Perform connection failure entirely in kernel space") has the following regressions/bugs that this patch fixes: 1. It can return cmds to upper layers like dm-multipath where that can retry them. After they are successful the fs/app can send new I/O to the same sectors, but we've left the cmds running in FW or in the net layer. We need to be calling ep_disconnect if userspace is not up. This patch only fixes the issue for offload drivers. iscsi_tcp will be fixed in separate commit because it doesn't have a ep_disconnect call. 2. The drivers that implement ep_disconnect expect that it's called before conn_stop. Besides crashes, if the cleanup_task callout is called before ep_disconnect it might free up driver/card resources for session1 then they could be allocated for session2. But because the driver's ep_disconnect is not called it has not cleaned up the firmware so the card is still using the resources for the original cmd. 3. The stop_conn_work_fn can run after userspace has done its recovery and we are happily using the session. We will then end up with various bugs depending on what is going on at the time. We may also run stop_conn_work_fn late after userspace has called stop_conn and ep_disconnect and is now going to call start/bind conn. If stop_conn_work_fn runs after bind but before start, we would leave the conn in a unbound but sort of started state where IO might be allowed even though the drivers have been set in a state where they no longer expect I/O. 4. Returning -EAGAIN in iscsi_if_destroy_conn if we haven't yet run the in kernel stop_conn function is breaking userspace. We should have been doing this for the caller.

Subsequent commits allow the kernel to do ep_disconnect. In that case we will have to get a proper refcount on the ep so one thread does not delete it from under another.

2021-06-02scsi: iscsi: Stop queueing during ep_disconnectMike Christie2-0/+2
During ep_disconnect we have been doing iscsi_suspend_tx/queue to block new I/O but every driver except cxgbi and iscsi_tcp can still get I/O from __iscsi_conn_send_pdu() if we haven't called iscsi_conn_failure() before ep_disconnect. This could happen if we were terminating the session, and the logout timed out before it was even sent to libiscsi. Fix the issue by adding a helper which reverses the bind_conn call that allows new I/O to be queued. Drivers implementing ep_disconnect can use this to make sure new I/O is not queued to them when handling the disconnect.
