[net-next,v4,00/15] net/smc: extend diagnostic netlink interface

Message

Karsten Graul Nov. 9, 2020, 3:17 p.m. UTC

Please apply the following patch series for smc to netdev's net-next tree.

This patch series refactors the current netlink API in smc_diag module
which is used for diagnostic purposes and extends the netlink API in a
backward compatible way so that the extended API can provide information
about SMC linkgroups, links and devices (both for SMC-R and SMC-D) and
can still work with the legacy netlink API.

Please note that patch 9 triggers a checkpatch warning because a comment
line was added using the style of the already existing comment block.

v2: In patch 10, 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.

Guvenc Gulce (14):
  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 the netlink reply processing routine
  net/smc: Add ability to work with extended SMC netlink API
  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
  net/smc: Refactor smc ism v2 capability handling
  net/smc: Add support for obtaining system information

Karsten Graul (1):
  net/smc: use helper smc_conn_abort() in listen processing
