2020-05-21 | IB/ipoib: Increase ipoib Datagram mode MTU's upper limit | Kaike Wan | |
Currently the ipoib UD mtu is restricted to 4K bytes. Remove this limitation so that the IPOIB module can potentially use an MTU (in UD mode) that is bounded by the MTU of the underlying device. A field is added to the ib_port_attr structure to indicate the maximum physical MTU the underlying device supports.

2020-05-21 | IB/{rdmavt, hfi1}: Implement creation of accelerated UD QPs | Gary Leshner | |
Adds capability to create a qpn to be recognized as an accelerated UD QP for ipoib. This is accomplished by reserving 0x81 in byte[0] of the qpn as the prefix for these qp types and reserving qpns between 0x810000 and 0x81ffff. The hfi1 capability mask already contained a flag for the VNIC netdev. This has been renamed and extended to include both VNIC and ipoib. The rvt code to allocate qps now recognizes this flag and sets 0x81 into byte[0] of the qpn. The code to allocate qpns is modified to reset the qpn numbering when it is detected that a value is located in byte[0] for a UD QP and it is a qpn being requested for net dev use. If it is a regular UD QP then it is allowable to have bits set in byte[0] of the qpn and provide the previously normal behavior. The code to free the qpn now checks for the AIP prefix value of 0x81 and removes it from the qpn before being freed so that the lower 16 bit number can be reused. This patch requires minor changes in the IB core and ipoib to facilitate the creation of accelerated UP QPs.

2020-05-06 | RDMA: Allow ib_client's to fail when add() is called | Jason Gunthorpe | |
When a client is added it isn't allowed to fail, but all the client's have various failure paths within their add routines. This creates the very fringe condition where the client was added, failed during add and didn't set the client_data. The core code will then still call other client_data centric ops like remove(), rename(), get_nl_info(), and get_net_dev_by_params() with NULL client_data - which is confusing and unexpected. If the add() callback fails, then do not call any more client ops for the device, even remove. Remove all the now redundant checks for NULL client_data in ops callbacks. Update all the add() callbacks to return error codes appropriately. EOPNOTSUPP is used for cases where the ULP does not support the ib_device - eg because it only works with IB.

2020-03-26 | IB/iser: Always check sig MR before putting it to the free pool | Sergey Gorenko | |
libiscsi calls the check_protection transport handler only if SCSI-Respose is received. So, the handler is never called if iSCSI task is completed for some other reason like a timeout or error handling. And this behavior looks correct. But the iSER does not handle this case properly because it puts a non-checked signature MR to the free pool. Then the error occurs at reusing the MR because it is not allowed to invalidate a signature MR without checking. This commit adds an extra check to iser_unreg_mem_fastreg(), which is a part of the task cleanup flow. Now the signature MR is checked there if it is needed.

2020-02-20 | RDMA: Replace zero-length array with flexible-array member | Gustavo A. R. Silva | |
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

iscsit_close_connection() calls isert_wait_conn(). Due to commit e9d3009cb936 both functions call target_wait_for_sess_cmds() although that last function should be called only once. Fix this by removing the target_wait_for_sess_cmds() call from isert_wait_conn() and by only calling isert_wait_conn() after target_wait_for_sess_cmds().

2020-01-15 | IB/srp: Never use immediate data if it is disabled by a user | Sergey Gorenko | |
Some SRP targets that do not support specification SRP-2, put the garbage to the reserved bits of the SRP login response. The problem was not detected for a long time because the SRP initiator ignored those bits. But now one of them is used as SRP_LOGIN_RSP_IMMED_SUPP. And it causes a critical error on the target when the initiator sends immediate data. The ib_srp module has a use_imm_date parameter to enable or disable immediate data manually. But it does not help in the above case, because use_imm_date is ignored at handling the SRP login response. The problem is definitely caused by a bug on the target side, but the initiator's behavior also does not look correct. The initiator should not use immediate data if use_imm_date is disabled by a user. This commit adds an additional checking of use_imm_date at the handling of SRP login response to avoid unexpected use of immediate data.

2019-11-25 | Merge branch 'ib-guids' into rdma.git for-next | Jason Gunthorpe | |
Danit Goldberg says: ==================== This series extends RTNETLINK to provide IB port and node GUIDs, which were configured for Infiniband VFs. The functionality to set VF GUIDs already existed for a long time, and here we are adding the missing "get" so that netlink will be symmetric and various cloud orchestration tools will be able to manage such VFs more naturally. The iproute2 was extended too to present those GUIDs. - ip link show <device> For example: - ip link set ib4 vf 0 node_guid 22:44:33:00:33:11:00:33 - ip link set ib4 vf 0 port_guid 10:21:33:12:00:11:22:10 - ip link show ib4 ib4: <BROADCAST,MULTICAST> mtu 4092 qdisc noop state DOWN mode DEFAULT group default qlen 256 link/infiniband 00:00:0a:2d:fe:80:00:00:00:00:00:00:ec:0d:9a:03:00:44:36:8d brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff vf 0 link/infiniband 00:00:0a:2d:fe:80:00:00:00:00:00:00:ec:0d:9a:03:00:44:36:8d brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff, spoof checking off, NODE_GUID 22:44:33:00:33:11:00:33, PORT_GUID 10:21:33:12:00:11:22:10, link-state disable, trust off, query_rss off ==================== Based on the mlx5-next branch from git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux for dependencies * branch 'ib-guids': (35 commits) IB/mlx5: Implement callbacks for getting VFs GUID attributes IB/ipoib: Add ndo operation for getting VFs GUID attributes IB/core: Add interfaces to get VF node and port GUIDs net/core: Add support for getting VF GUIDs net/mlx5: Add new chain for netfilter flow table offload net/mlx5: Refactor creating fast path prio chains net/mlx5: Accumulate levels for chains prio namespaces net/mlx5: Define fdb tc levels per prio net/mlx5: Rename FDB_* tc related defines to FDB_TC_* defines net/mlx5: Simplify fdb chain and prio eswitch defines IB/mlx5: Load profile according to RoCE enablement state IB/mlx5: Rename profile and init methods net/mlx5: Handle "enable_roce" devlink param net/mlx5: Document flow_steering_mode devlink param devlink: Add new "enable_roce" generic device param net/mlx5: fix spelling mistake "metdata" -> "metadata" net/mlx5: fix kvfree of uninitialized pointer spec IB/mlx5: Introduce and use mlx5_core_is_vf() net/mlx5: E-switch, Enable metadata on own vport net/mlx5: Refactor ingress acl configuration ...

2019-10-28 | RDMA/srpt: Fix TPG creation | Bart Van Assche | |
Unlike the iSCSI target driver, for the SRP target driver it is sufficient if a single TPG can be associated with each RDMA port name. However, users started associating multiple TPGs with RDMA port names. Support this by converting the single TPG in struct srpt_port_id into a list. This patch fixes the following list corruption issue: list_add corruption. prev->next should be next (ffffffffc0a080c0), but was ffffa08a994ce6f0. (prev=ffffa08a994ce6f0).
