From: Ursula Braun <ursula.braun@xxxxxxxxxxxxxxxxxx> Dave, thanks for your feedback and pointing out the kernel_setsockopt() problem(s) in patch 2/4. Here is now version 2 of the patch series with patches 2-4 implementing sockopts that require special handling in SMC. Version 2 changes of Patch 2/4 (and 3/4): * return error -EOPNOTSUPP for TCP_FASTOPEN sockopts * fix a kernel_setsockopt() usage bug by switching parameter variable from type "u8" to "int" * add return code validation when calling kernel_setsockopt() * propagate a setsockopt error on the internal CLC socket to the SMC socket. Regards, Ursula Karsten Graul (1): net/smc: fix structure size Ursula Braun (3): net/smc: handle sockopt TCP_NODELAY net/smc: handle sockopt TCP_CORK net/smc: handle sockopt TCP_DEFER_ACCEPT net/smc/af_smc.c | 193 ++++++++++++++++++++++++++++++++++++++++++++++++++++-- net/smc/smc.h | 12 ++++ net/smc/smc_cdc.c | 2 +- net/smc/smc_cdc.h | 2 +- net/smc/smc_rx.c | 2 +- net/smc/smc_rx.h | 1 + net/smc/smc_tx.c | 16 ++++- net/smc/smc_tx.h | 8 +++ 8 files changed, 225 insertions(+), 11 deletions(-) -- 2.13.5 -- To unsubscribe from this list: send the line "unsubscribe linux-s390" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
