Move the __attribute_const__ declarations such that sparse understands that these apply to the function itself and not to the return type. This avoids that sparse reports error messages like the following: drivers/infiniband/core/verbs.c:73:12: error: symbol 'ib_event_msg' redeclared with different type (originally declared at include/rdma/ib_verbs.h:470) - different modifiers Fixes: 2b1b5b60 ("IB/core, cma: Nice log-friendly string helpers") Signed-off-by:

Instead of constructing a page list, call ib_map_mr_sg and post a new ib_reg_wr. srp_map_finish_fr now returns the number of sg elements registered. Remove srp_finish_mapping since no one is calling it. Signed-off-by:

This is a preparation patch for the new registration API conversion. It splits srp_map_sg per registration strategy (srp_map_sg[fmr|fr|dma]. On its own it adds some code duplication, but it makes the API switch easier to comprehend. Signed-off-by:

The new fast registration verb ib_map_mr_sg receives a scatterlist and converts it to a page list under the verbs API thus hiding the specific HW mapping details away from the consumer. The provider drivers are provided with a generic helper ib_sg_to_pages that converts a scatterlist into a vector of page addresses. The drivers can still perform any HW specific page address setting by passing a set_page function pointer which will be invoked for each page address. This allows drivers to avoid keeping a shadow page vectors and convert them to HW specific translations by doing extra copies. This API will allow ULPs to remove the duplicated code of constructing a page vector from a given sg list. The send work request ib_reg_wr also shrinks as it will contain only mr, key and access flags in addition. Signed-off-by:

Add support for network namespaces in the ib_cma module. This is accomplished by: 1. Adding network namespace parameter for rdma_create_id. This parameter is used to populate the network namespace field in rdma_id_private. rdma_create_id keeps a reference on the network namespace. 2. Using the network namespace from the rdma_id instead of init_net inside of ib_cma, when listening on an ID and when looking for an ID for an incoming request. 3. Decrementing the reference count for the appropriate network namespace when calling rdma_destroy_id. In order to preserve the current behavior init_net is passed when calling from other modules.

Keep a struct for each network namespace containing the IDRs for the RDMA CM port spaces. The struct is created dynamically using the generic_net mechanism. This patch is internal infrastructure work for the following patches. In this patch, init_net is statically used as the network namespace for the new port-space API. Signed-off-by:

Add network namespace support to the ib_addr module. For that, all the address resolution and matching should be done using the appropriate namespace instead of init_net. This is achieved by: 1. Adding an explicit network namespace argument to exported function that require a namespace. 2. Saving the namespace in the rdma_addr_client structure. 3. Using it when calling networking functions. In order to preserve the behavior of calling modules, &init_net is passed as the parameter in calls from other modules. This is modified as namespace support is added on more levels. Signed-off-by:

iser is perfectly capable supporting SG clustering as it translates the SG list to a page vector. Enabling SG clustering can dramatically reduce the number of SG elements, which doesn't make much of a difference at this point, but with arbitrary SG list support, reducing the number of SG elements can benefit greatly as as it would reduce the length of the HW descriptors array.

The block layer can reliably guarantee that SG lists won't contain gaps (page unaligned) if a driver set the queue virt_boundary. With this setting the block layer will: - refuse merges if bios are not aligned to the virtual boundary - split bios/requests that are not aligned to the virtual boundary - or, bounce buffer SG_IOs that are not aligned to the virtual boundary Since iser is working in 4K page size, set the virt_boundary to 4K pages. With this setting, we can now safely remove the bounce buffering logic in iser. Signed-off-by:

The GID cache accompanies every GID with attributes. The GID attributes link the GID with its netdevice, which could be resolved to smac and vlan id easily. Since we've added the netdevice (ifindex and net) to the path record, storing the L2 attributes is duplicated data and hence these attributes are removed. Signed-off-by:
