net/smc: Extend SMCR v2 linkgroup netlink attribute

2023-08-19T11:46:53+00:00

Add SMC_NLA_LGR_R_V2_MAX_CONNS and SMC_NLA_LGR_R_V2_MAX_LINKS to SMCR v2 linkgroup netlink attribute SMC_NLA_LGR_R_V2 for linkgroup's detail info showing. Signed-off-by: Guangguan Wang Reviewed-by: Jan Karcher Signed-off-by: David S. Miller

net/smc: Extend SMC-R link group netlink attribute

2022-07-18T10:19:17+00:00

Extend SMC-R link group netlink attribute SMC_GEN_LGR_SMCR. Introduce SMC_NLA_LGR_R_BUF_TYPE to show the buffer type of SMC-R link group. Signed-off-by: Wen Gu Signed-off-by: David S. Miller

net/smc: Add global configure for handshake limitation by netlink

2022-02-11T11:14:58+00:00

Although we can control SMC handshake limitation through socket options, which means that applications who need it must modify their code. It's quite troublesome for many existing applications. This patch modifies the global default value of SMC handshake limitation through netlink, providing a way to put constraint on handshake without modifies any code for applications.

net/smc: Dynamic control handshake limitation by socket options

2022-02-11T11:14:58+00:00

This patch aims to add dynamic control for SMC handshake limitation for every smc sockets, in production environment, it is possible for the same applications to handle different service types, and may have different opinion on SMC handshake limitation. This patch try socket options to complete it, since we don't have socket option level for SMC yet, which requires us to implement it at the same time. This patch does the following: - add new socket option level: SOL_SMC. - add new SMC socket option: SMC_LIMIT_HS. - provide getter/setter for SMC socket options.

net/smc: Add netlink net namespace support

2022-01-02T12:07:39+00:00

This adds net namespace ID to diag of linkgroup, helps us to distinguish different namespaces, and net_cookie is unique in the whole system. Signed-off-by: Tony Lu Signed-off-by: David S. Miller

net/smc: add netlink support for SMC-Rv2

net/smc: add generic netlink support for system EID

2021-09-14T11:49:10+00:00

With SMC-Dv2 users can configure if the static system EID should be used during CLC handshake, or if only user EIDs are allowed. Add generic netlink support to enable and disable the system EID, and to retrieve the system EID and its current enabled state.

net/smc: add support for user defined EIDs

2021-09-14T11:49:10+00:00

SMC-Dv2 allows users to define EIDs which allows to create separate name spaces enabling users to cluster their SMC-Dv2 connections. Add support for user defined EIDs and extent the generic netlink interface so users can add, remove and dump EIDs.
