2021-10-18treewide: Replace open-coded flex arrays in unionsKees Cook1-2/+2
In support of enabling -Warray-bounds and -Wzero-length-bounds and correctly handling run-time memcpy() bounds checking, replace all open-coded flexible arrays (i.e. 0-element arrays) in unions with the DECLARE_FLEX_ARRAY() helper macro. This fixes warnings such as: fs/hpfs/anode.c: In function 'hpfs_add_sector_to_btree': fs/hpfs/anode.c:209:27: warning: array subscript 0 is outside the bounds of an interior zero-length array 'struct bplus_internal_node[0]' [-Wzero-length-bounds] 209 | anode->btree.u.internal[0].down = cpu_to_le32(a); | ~~~~~~~~~~~~~~~~~~~~~~~^~~ In file included from fs/hpfs/hpfs_fn.h:26, from fs/hpfs/anode.c:10: fs/hpfs/hpfs.h:412:32: note: while referencing 'internal' 412 | struct bplus_internal_node internal[0]; /* (internal) 2-word entries giving | ^~~~~~~~ drivers/net/can/usb/etas_es58x/es58x_fd.c: In function 'es58x_fd_tx_can_msg': drivers/net/can/usb/etas_es58x/es58x_fd.c:360:35: warning: array subscript 65535 is outside the bounds of an interior zero-length array 'u8[0]' {aka 'unsigned char[]'} [-Wzero-length-bounds] 360 | tx_can_msg = (typeof(tx_can_msg))&es58x_fd_urb_cmd->raw_msg[msg_len]; | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In file included from drivers/net/can/usb/etas_es58x/es58x_core.h:22, from drivers/net/can/usb/etas_es58x/es58x_fd.c:17: drivers/net/can/usb/etas_es58x/es58x_fd.h:231:6: note: while referencing 'raw_msg' 231 | u8 raw_msg[0]; | ^~~~~~~ Cc: "Gustavo A.

Make changes to rdma_user_rxe.h to allow indexing AH objects, passing the index in UD send WRs to the driver and returning the index to the rxe provider. Modify rxe_create_ah() to add an index to AH when created and if called from a new user provider return it to user space. If called from an old provider mark the AH as not having a useful index.

2021-10-12RDMA/rxe: Move AV from rxe_send_wqe to rxe_send_wrBob Pearson1-1/+3
Move the struct rxe_av av from struct rxe_send_wqe to struct rxe_send_wr placing it in wr.ud at the same offset as it was previously. This has the effect of increasing the size of struct rxe_send_wr while keeping the size of struct rxe_send_wqe the same. This better reflects the use of this field which is only used for UD sends. This change has no effect on ABI compatibility so the modified rxe driver will operate with older versions of rdma-core.

2021-10-06RDMA/efa: CQ notificationsGal Pressman1-3/+15
This patch adds support for CQ notifications through the standard verbs api. In order to achieve that, a new event queue (EQ) object is introduced, which is in charge of reporting completion events to the driver. On driver load, EQs are allocated and their affinity is set to a single cpu. When a user app creates a CQ with a completion channel, the completion vector number is converted to a EQ number, which is in charge of reporting the CQ events. In addition, the CQ creation admin command now returns an offset for the CQ doorbell, which is mapped to the userspace provider and is used to arm the CQ when requested by the user. The EQs use a single doorbell (located on the registers BAR), which encodes the EQ number and arm as part of the doorbell value. The EQs are polled by the driver on each new EQE, and arm it when the poll is completed.

2021-07-20RDMA/mlx5: Add DCS offload supportLior Nahmanson1-2/+15
DCS is an offload to SW load balancing of DC initiator work requests. A single DCI can be connected to only one target at the time and can't start new connection until the previous work request is completed. This limitation will cause to delay when the initiator process needs to transfer data to multiple targets at the same time. The SW solution is to use a process that handling and spreading the work request on many DCIs according to destinations. This feature is an offload to this process and coming to reduce the load from the CPU and improve the performance.

Currently, if the user asks for a real-time timestamp, the device will return a free-running one, and the timestamp will be translated to real-time in the user-space. When the device supports only real-time timestamp and not free-running, the creation of the QP will fail even though the user needs supported the real-time one. To prevent this, we will return the real-time timestamp directly from the device.

In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memcpy(), memmove(), and memset(), avoid intentionally reading across neighboring array fields. Without a flexible array, this looks like an attempt to perform a memcpy() read beyond the end of the packet->mad.data array: drivers/infiniband/core/user_mad.c: memcpy(packet->msg->mad, packet->mad.data, IB_MGMT_MAD_HDR); Switch from [0] to [] to use the appropriately handled type for trailing bytes.

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/[email protected] Signed-off-by: Jason Gunthorpe <[email protected]> * 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

2021-04-27RDMA/nldev: Add copy-on-fork attribute to get sys commandGal Pressman1-0/+3
The new attribute indicates that the kernel copies DMA pages on fork, hence libibverbs' fork support through madvise and MADV_DONTFORK is not needed. The introduced attribute is always reported as supported since the kernel has the patch that added the copy-on-fork behavior. This allows the userspace library to identify older vs newer kernel versions. Extra care should be taken when backporting this patch as it relies on the fact that the copy-on-fork patch is merged, hence no check for support is added. Don't backport this patch unless you also have the following series: commit 70e806e4e645 ("mm: Do early cow for pinned pages during fork() for ptes") and commit 4eae4efa2c29 ("hugetlb: do early cow when page pinned on src mm").

Manage refcount on the mlx5_ib_dm object, so it would be keep valid until all addresses were unmapped.

2021-03-11RDMA/mlx5: Allow larger pages in DevX umemJason Gunthorpe1-0/+1
The umem DMA list calculation was locked at 4k pages due to confusion around how this API works and is used when larger pages are present. The conclusion is: - umem's cannot extend past what is mapped into the process, so creating a lage page size and referring to a sub-range is not allowed - umem's must always have a page offset of zero, except for sub PAGE_SIZE umems - The feature of umem_offset to create multiple objects inside a umem is buggy and isn't used anyplace. Thus we can assume all users of the current API have umem_offset == 0 as well Provide a new page size calculator that limits the DMA list to the VA range and enforces umem_offset == 0. Allow user space to specify the page sizes which it can accept, this bitmap must be derived from the intended use of the umem, based on per-usage HW limitations.

2021-01-19RDMA/vmw_pvrdma: Fix network_hdr_type reported in WCBryan Tan1-0/+7
The PVRDMA device HW interface defines network_hdr_type according to an old definition of the internal kernel rdma_network_type enum that has since changed, resulting in the wrong rdma_network_type being reported. Fix this by explicitly defining the enum used by the PVRDMA device and adding a function to convert the pvrdma_network_type to rdma_network_type enum.
