Previous version of this patch series was using the sock_diag netlink infrastructure. This version is using the generic netlink API. Generic netlink API offers a better type safety between kernel and userspace communication. Using the generic netlink API, smc module can provide now information about SMC linkgroups, links and devices (both for SMC-R and SMC-D). v2: Add missing include to uapi header smc_diag.h. v3: Apply code style recommendations from review comments. Instead of using EXPORTs to allow the smc_diag module to access data of the smc module, introduce struct smc_diag_ops and let smc_diag access the required data using function pointers. v4: Address checkpatch.pl warnings. Do not use static inline for functions. v5: Use generic netlink API instead of the sock_diag netlink infrastructure. Guvenc Gulce (13): net/smc: Use active link of the connection net/smc: Add connection counters for links net/smc: Add link counters for IB device ports net/smc: Add diagnostic information to smc ib-device net/smc: Add diagnostic information to link structure net/smc: Refactor smc ism v2 capability handling net/smc: Introduce generic netlink interface for diagnostic purposes net/smc: Add support for obtaining system information net/smc: Introduce SMCR get linkgroup command net/smc: Introduce SMCR get link command net/smc: Add SMC-D Linkgroup diagnostic support net/smc: Add support for obtaining SMCD device list net/smc: Add support for obtaining SMCR device list Karsten Graul (1): net/smc: use helper smc_conn_abort() in listen processing include/uapi/linux/smc.h | 126 ++++++++++++ net/smc/Makefile | 2 +- net/smc/af_smc.c | 33 ++-- net/smc/smc_clc.c | 5 + net/smc/smc_clc.h | 1 + net/smc/smc_core.c | 407 ++++++++++++++++++++++++++++++++++++++- net/smc/smc_core.h | 49 +++++ net/smc/smc_diag.c | 23 +-- net/smc/smc_ib.c | 204 ++++++++++++++++++++ net/smc/smc_ib.h | 6 + net/smc/smc_ism.c | 103 +++++++++- net/smc/smc_ism.h | 6 +- net/smc/smc_netlink.c | 104 ++++++++++ net/smc/smc_netlink.h | 32 +++ net/smc/smc_pnet.c | 2 + 15 files changed, 1059 insertions(+), 44 deletions(-) create mode 100644 net/smc/smc_netlink.c create mode 100644 net/smc/smc_netlink.h
