nvme: Have NVME_FABRICS select NVME_CORE instead of transport drivers

2021-08-16T19:03:18Z

Transport drivers need both core and fabrics modules, instead of selecting both, have the selection transitive such that NVME_FABRICS selects NVME_CORE and transport drivers select NVME_FABRICS.

nvmet-tcp: add NVMe over TCP target driver

2018-12-13T08:58:57Z

This patch implements the TCP transport driver for the NVMe over Fabrics target stack. This allows exporting NVMe over Fabrics functionality over good old TCP/IP. The driver implements the TP 8000 of how nvme over fabrics capsules and data are encapsulated in nvme-tcp pdus and exchaged on top of a TCP byte stream. nvme-tcp header and data digest are supported as well.

IB: Revert "remove redundant INFINIBAND kconfig dependencies"

2018-05-28T16:40:16Z

Several subsystems depend on INFINIBAND_ADDR_TRANS, which in turn depends on INFINIBAND. However, when with CONFIG_INIFIBAND=m, this leads to a link error when another driver using it is built-in. The INFINIBAND_ADDR_TRANS dependency is insufficient here as this is a 'bool' symbol that does not force anything to be a module in turn. fs/cifs/smbdirect.o: In function `smbd_disconnect_rdma_work': smbdirect.c:(.text+0x1e4): undefined reference to `rdma_disconnect' net/9p/trans_rdma.o: In function `rdma_request': trans_rdma.c:(.text+0x7bc): undefined reference to `rdma_disconnect' net/9p/trans_rdma.o: In function `rdma_destroy_trans': trans_rdma.c:(.text+0x830): undefined reference to `ib_destroy_qp' trans_rdma.c:(.text+0x858): undefined reference to `ib_dealloc_pd' Fixes: 9533b292a7ac ("IB: remove redundant INFINIBAND kconfig dependencies") Signed-off-by: Arnd Bergmann Acked-by: Greg Thelen Signed-off-by: Jason Gunthorpe

IB: remove redundant INFINIBAND kconfig dependencies

2018-05-09T12:51:03Z

INFINIBAND_ADDR_TRANS depends on INFINIBAND. So there's no need for options which depend INFINIBAND_ADDR_TRANS to also depend on INFINIBAND. Remove the unnecessary INFINIBAND depends. Signed-off-by: Greg Thelen Signed-off-by: Doug Ledford

NVME_TARGET_RDMA code depends on INFINIBAND_ADDR_TRANS provided symbols. So declare the kconfig dependency. This is necessary to allow for enabling INFINIBAND without INFINIBAND_ADDR_TRANS. Signed-off-by: Greg Thelen Cc: Tarick Bedeir Signed-off-by: Doug Ledford
