After users sets the ECE option, FW will return the agreed/supported bits through an output structures of modify QP stages for regular QPs or through create QP for the DCT. Link: https://lore.kernel.org/r/20200526115440.205922-9-leon@kernel.orgReviewed-by:

The most common way to set ECE option will be during modify QP command in INIT2RTR, RTR2RTS and RTS2RTS stages, so update mlx5 to support it. The new bit in the comp_mask is needed to mark that kernel supports ECE and can receive data instead of "reserved" field in the struct mlx5_ib_modify_qp.

Allow users to ask creation of QPs with specific ECE options. Such early set even before RDMA-CM connection is established is useful if user knows exactly which option he needs. Link: https://lore.kernel.org/r/20200526115440.205922-4-leon@kernel.orgReviewed-by:

Supported ECE options are returned from FW in the create_qp phase and zero means that field is not valid. Such default value allows us to reuse reserved field without worries about comp_mask. Update create QP API to return ECE options. Link: https://lore.kernel.org/r/20200526115440.205922-3-leon@kernel.orgReviewed-by:

IBTA declares "vendor option not supported" reject reason in REJ messages if passive side doesn't want to accept proposed ECE options. Due to the fact that ECE is managed by userspace, there is a need to let users to provide such rejected reason. Link: https://lore.kernel.org/r/20200526103304.196371-7-leon@kernel.orgSigned-off-by:

The rdma_accept() is called by both passive and active sides of CMID connection to mark readiness to start data transfer. For passive side, this is called explicitly, for active side, it is called implicitly while receiving REP message. Provide ECE data to rdma_accept function needed for passive side to send that REP message. Link: https://lore.kernel.org/r/20200526103304.196371-6-leon@kernel.orgSigned-off-by:

Passive side of CMID connection receives ECE request through REQ message and needs to respond with relevant REP message which will be forwarded to active side. The UCMA events interface is responsible for such communication with the user space (librdmacm). Extend it to provide ECE wire data.

The end result of RDMA-CM ECE handshake is ECE options, which is needed to be used while configuring data QPs. Such options can come in any QP state, so add in/out fields to set and query ECE options. OUT fields: * create_qp() - default ECE options for that type of QP. * modify_qp() - enabled ECE options after QP state transition. IN fields: * create_qp() - create QP with this ECE option. * modify_qp() - requested options. For unconnected QPs, the FW will return an error if ECE is already configured with any options that not equal to previously set. Reviewed-by:

Currently, the MTR region is configed before hns_roce_mtr_map() is invoked, but in some scenarios, the region is configed at MTR creation, the caller need to store this config and call hns_roce_mtr_map() later.

Get rid of the macros and just use a for loop iterating over the list of paths in both places. It is easier to read and also less lines of code.

module_is_live function is only defined when CONFIG_MODULES is enabled. Use try_module_get instead to check whether the module is being removed. When module unload and manuall unmapping is happening in parallel, we can try removing the symlink twice: rnbd_client_exit vs. rnbd_clt_unmap_dev_store. This is probably not the best way to deal with this race in general, but for now this fixes the compilation issue when CONFIG_MODULES is disabled and has no functional impact. Regression tests passed. Fixes: 1eb54f8f ("block/rnbd: client: sysfs interface functions") Link: https://lore.kernel.org/r/20200521185909.457245-1-danil.kipnis@cloud.ionos.comReported-by:
