Hi, This is v4 of the series where the tw_timer is un-pinned to get rid of interferences in isolated CPUs setups. Eric mentionned rsk_timer needs looking into, but I haven't had the time to do that. It doesn't show up in our testing, which might be due to its relatively low timeout (IIUC 3s). Revisions ========= v3 -> v2 ++++++++ o Rebased against latest Linus' tree o Added ehash lock usage to serialize scheduling vs descheduling of the tw_timer (Paolo) v2 -> v3 ++++++++ o Dropped bh_disable patch o Rebased against latest Linus' tree RFCv1 -> v2 ++++++++ o Added comment in inet_twsk_deschedule_put() to highlight the race o Added bh_disable patch Valentin Schneider (1): tcp/dcpp: Un-pin tw_timer include/net/inet_timewait_sock.h | 6 ++-- net/dccp/minisocks.c | 9 +++-- net/ipv4/inet_timewait_sock.c | 59 +++++++++++++++++++++++--------- net/ipv4/tcp_minisocks.c | 9 +++-- 4 files changed, 55 insertions(+), 28 deletions(-) -- 2.43.0
