From mboxrd@z Thu Jan 1 00:00:00 1970 From: Ursula Braun Subject: [PATCH V3 net-next 0/3] TCP experimental option for SMC rendezvous Date: Wed, 25 Oct 2017 11:01:43 +0200 Message-ID: <20171025090146.83471-1-ubraun@linux.vnet.ibm.com> Return-path: Sender: netdev-owner@vger.kernel.org List-Archive: List-Post: To: davem@davemloft.net Cc: netdev@vger.kernel.org, linux-s390@vger.kernel.org, jwi@linux.vnet.ibm.com, schwidefsky@de.ibm.com, heiko.carstens@de.ibm.com, raspl@linux.vnet.ibm.com, ubraun@linux.vnet.ibm.com List-ID: Dave, SMC-capability is to be negotiated with a TCP experimental option. As requested during code review of our previous approach using netfilter hooks, here's a new version. It touches tcp-code in the first patch and exploits the new tcp flag in the smc-code. Kind regards, Ursula Changelog: V3: * move include for linux/unaligned/access_ok.h to tcp_input.c V2: * switch to current jump labels API * remove static key checking in smc_set_capability() (comment from Eric Dumazet) * use inet_request_sock parameter for smc_set_option_cond() * smc_listen_work(): replace local variable lgr_lock_taken by new labels and separate this change into a prerequisite first patch Ursula Braun (3): smc: fix mutex unlocks during link group creation tcp: TCP experimental option for SMC smc: add SMC rendezvous protocol include/linux/tcp.h | 9 +++++-- include/net/inet_sock.h | 3 ++- include/net/tcp.h | 7 ++++++ net/ipv4/tcp.c | 6 +++++ net/ipv4/tcp_input.c | 35 +++++++++++++++++++++++++++ net/ipv4/tcp_minisocks.c | 19 +++++++++++++++ net/ipv4/tcp_output.c | 63 +++++++++++++++++++++++++++++++++++++++++++++--- net/smc/af_smc.c | 42 +++++++++++++++++++++++--------- 8 files changed, 167 insertions(+), 17 deletions(-) -- 2.13.5
