2018-09-26RDMA: Fully setup the device name in ib_register_deviceJason Gunthorpe1-3/+1
The current code has two copies of the device name, ibdev->dev and dev_name(&ibdev->dev), and they are setup at different times, which is very confusing. Set them both up at the same time and make dev_name() the lead name, which is the proper use of the driver core APIs. To make it very clear that the name is not valid until registration pass it in to the ib_register_device() call rather than messing with ibdev->name directly. Also the reorganization now checks that dev_name is unique even if it does not contain a %.

2018-07-30RDMA, core and ULPs: Declare ib_post_send() and ib_post_recv() arguments constBart Van Assche4-25/+25
Since neither ib_post_send() nor ib_post_recv() modify the data structure their second argument points at, declare that argument const. This change makes it necessary to declare the 'bad_wr' argument const too and also to modify all ULPs that call ib_post_send(), ib_post_recv() or ib_post_srq_recv(). This patch does not change any functionality but makes it possible for the compiler to verify whether the ib_post_(send|recv|srq_recv) really do not modify the posted work request. To make this possible, only one cast had to be introduce that casts away constness, namely in rpcrdma_post_recvs(). The only way I can think of to avoid that cast is to introduce an additional loop in that function or to change the data type of bad_wr from struct ib_recv_wr ** into int (an index that refers to an element in the work request list). However, both approaches would require even more extensive changes than this patch.

2018-07-10RDMA: Fix storage of PortInfo CapabilityMask in the kernelJason Gunthorpe1-1/+1
The internal flag IP_BASED_GIDS was added to a field that was being used to hold the port Info CapabilityMask without considering the effects this will have. Since most drivers just use the value from the HW MAD it means IP_BASED_GIDS will also become set on any HW that sets the IBA flag IsOtherLocalChangesNoticeSupported - which is not intended. Fix this by keeping port_cap_flags only for the IBA CapabilityMask value and store unrelated flags externally. Move the bit definitions for this to ib_mad.h to make it clear what is happening. To keep the uAPI unchanged define a new set of flags in the uapi header that are only used by ib_uverbs_query_port_resp.port_cap_flags which match the current flags supported in rdma-core, and the values exposed by the current kernel.

2018-06-18IB/core: add max_send_sge and max_recv_sge attributesSteve Wise1-1/+2
This patch replaces the ib_device_attr.max_sge with max_send_sge and max_recv_sge. It allows ulps to take advantage of devices that have very different send and recv sge depths. For example cxgb4 has a max_recv_sge of 4, yet a max_send_sge of 16. Splitting out these attributes allows much more efficient use of the SQ for cxgb4 with ulps that use the RDMA_RW API. Consider a large RDMA WRITE that has 16 scattergather entries. With max_sge of 4, the ulp would send 4 WRITE WRs, but with max_sge of 16, it can be done with 1 WRITE WR.

The core code now ensures that all driver callbacks that receive an rdma_ah_attrs will have a sgid_attr's pointer if there is a GRH present. Drivers can use this pointer instead of calling a query function with sgid_index. This simplifies the drivers and also avoids races where a gid_index lookup may return different data if it is changed.

Introduce AH attribute copy, move and replace APIs to be used by core and provider drivers. In CM code flow when ah attribute might be re-initialized twice while processing incoming request, or initialized once while from path record while sending out CM requests. Therefore use rdma_move_ah_attr API to handle such scenarios instead of memcpy(). Provider drivers keeps a copy ah_attr during the lifetime of the ah. Therefore, use rdma_replace_ah_attr() which conditionally release reference to old ah_attr and holds reference to new attribute whose referrence is released when the AH is freed.

2018-06-12treewide: kzalloc() -> kcalloc()Kees Cook2-4/+4
The kzalloc() function has a 2-factor argument form, kcalloc(). This patch replaces cases of: kzalloc(a * b, gfp) with: kcalloc(a * b, gfp) as well as handling cases of: kzalloc(a * b * c, gfp) with: kzalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kzalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kzalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kzalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kzalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

2018-05-23RDMA/qedr: Fix doorbell bar mapping for dpi > 1Kalderon, Michal1-31/+29
Each user_context receives a separate dpi value and thus a different address on the doorbell bar. The qedr_mmap function needs to validate the address and map the doorbell bar accordingly. The current implementation always checked against dpi=0 doorbell range leading to a wrong mapping for doorbell bar. (It entered an else case that mapped the address differently). qedr_mmap should only be used for doorbells, so the else was actually wrong in the first place. This only has an affect on arm architecture and not an issue on a x86 based architecture. This lead to doorbells not occurring on arm based systems and left applications that use more than one dpi (or several applications run simultaneously ) to hang.

There are lots of notes in the commit messages, but the basic summary is we don't think there is an actual 32 bit kernel user of drivers/infiniband for several good reasons. However we are seeing people want to use a 32 bit user space with 64 bit kernel, which didn't completely work today. So in fixing it we required a 32 bit rxe user to upgrade their userspace. rxe users are still already quite rare and we think a 32 bit one is non-existing. - Fix RDMA uapi headers to actually compile in userspace and be more complete - Three shared with netdev pull requests from Mellanox: * 7 patches, mostly to net with 1 IB related one at the back). This series addresses an IRQ performance issue (patch 1), cleanups related to the fix for the IRQ performance problem (patches 2-6), and then extends the fragmented completion queue support that already exists in the net side of the driver to the ib side of the driver (patch 7). * Mostly IB, with 5 patches to net that are needed to support the remaining 10 patches to the IB subsystem. This series extends the current 'representor' framework when the mlx5 driver is in switchdev mode from being a netdev only construct to being a netdev/IB dev construct. The IB dev is limited to raw Eth queue pairs only, but by having an IB dev of this type attached to the representor for a switchdev port, it enables DPDK to work on the switchdev device. * All net related, but needed as infrastructure for the rdma driver - Updates for the hns, i40iw, bnxt_re, cxgb3, cxgb4, hns drivers - SRP performance updates - IB uverbs write path cleanup patch series from Leon - Add RDMA_CM support to ib_srpt. This is disabled by default. Users need to set the port for ib_srpt to listen on in configfs in order for it to be enabled (/sys/kernel/config/target/srpt/discovery_auth/rdma_cm_port) - TSO and Scatter FCS support in mlx4 - Refactor of modify_qp routine to resolve problems seen while working on new code that is forthcoming - More refactoring and updates of RDMA CM for containers support from Parav - mlx5 'fine grained packet pacing', 'ipsec offload' and 'device memory' user API features - Infrastructure updates for the new IOCTL interface, based on increased usage - ABI compatibility bug fixes to fully support 32 bit userspace on 64 bit kernel as was originally intended.

2018-04-05RDMA/qedr: Fix wmb usage in qedrKalderon, Michal1-8/+18
This patch comes as a result of Sinan Kaya's work and the decision that writel() must be a strong enough barrier for DMA. wmb usages in qedr driver have either been removed where they were there only to order DMA accesses, and replaced with smp_wmb and comments for the places that the barrier was there for SMP reasons.
