smb: smbdirect: let smbdirect_connection_deregister_mr_io unlock while waiting

2026-04-16T02:58:24Z

We should not hold a mutex locked during wait_for_completion() holding a reference is enough.

smb: smbdirect: fix the logic in smbdirect_socket_destroy_sync() without an error

2026-04-16T02:58:24Z

If smbdirect_socket_destroy_sync() and sc->first_error was not set we should set -ESHUTDOWN, that's a better condition doing it only implicitly with the sc->status < SMBDIRECT_SOCKET_DISCONNECTING check.

smb: smbdirect: fix copyright header of smbdirect.h

2026-04-16T02:58:24Z

Everything in smbdirect.h was taken from my out of tree prototype. Cc: Steve French Cc: Tom Talpey Cc: Long Li Cc: Namjae Jeon Cc: David Howells Cc: Henrique Carvalho Cc: linux-cifs@vger.kernel.org Cc: samba-technical@lists.samba.org Signed-off-by: Stefan Metzmacher Signed-off-by: Steve French

smb: smbdirect: change smbdirect_socket_parameters.{initiator_depth,responder_resources} to __u16

2026-04-16T02:58:24Z

We still limit this to U8_MAX as the rdma api only uses __u8 and that's also the limit for Infiniband and RoCE*, while iWarp would be able to support larger values at the protocol level. As struct smbdirect_socket_parameters will be part of the uapi for IPPROTO_SMBDIRECT in future, change it now even if userspace sockets won't be supported yet.

smb: smbdirect: remove unused SMBDIRECT_USE_INLINE_C_FILES logic

2026-04-16T02:58:24Z

We always build as standalone module (or as part of the core kernel). This also removes unused elements from struct smbdirect_socket and unused exports.

smb: smbdirect: introduce global workqueues

2026-04-16T02:58:24Z

These will be used in future and callers should no longer use smbdirect_socket_set_custom_workqueue().

smb: smbdirect: prepare use of dedicated workqueues for different steps

2026-04-16T02:58:24Z

This is a preparation in order to have global workqueues in the smbdirect module instead of having the caller to provide one.

smb: smbdirect: remove unused smbdirect_connection_mr_io_recovery_work()

2026-04-16T02:58:24Z

This would actually never be used as we only move to SMBDIRECT_MR_ERROR when we directly call smbdirect_socket_schedule_cleanup(). Doing an ib_dereg_mr/ib_alloc_mr dance on working connection is not needed and it's also pointless on a broken connection as we don't reuse any ib_pd.

smb: smbdirect: wrap rdma_disconnect() in rdma_[un]lock_handler()

2026-04-16T02:58:24Z

This might not be needed, but it controls the order of ib_drain_qp() and rdma_disconnect().

smb: smbdirect: introduce smbdirect_netdev_rdma_capable_mode_type()

2026-04-16T02:58:24Z

This is basically a copy of ksmbd_rdma_capable_netdev() in the server, but this also prints a message when a device is renamed. The differences are: - It uses rdma_for_each_port() instead of implementing the same logic again. - It returns RDMA_NODE_{UNSPECIFIED,IB_CA,RNIC} values instead of bool Cc: Steve French Cc: Tom Talpey Cc: Long Li Cc: Namjae Jeon Cc: linux-cifs@vger.kernel.org Cc: samba-technical@lists.samba.org Signed-off-by: Stefan Metzmacher Acked-by: Namjae Jeon Signed-off-by: Steve French
