Hi, The following batch contains IPVS fixes for net to address issues from the latest net-next pull request.
Julian Anastasov made the following summary: 1-3) Fixes for the recently added resizable hash tables 4) dest from trash can be leaked if ip_vs_start_estimator() fails 5) fixed races and locking for the estimation kthreads 6) fix for wrong roundup_pow_of_two() usage in the resizable hash tables 7-8) v2 of the changes from Waiman Long to properly guard against the housekeeping_cpumask() updates: https://lore.kernel.org/netfilter-devel/[email protected]/ I added missing Fixes tag. The original description: Since commit 041ee6f3727a ("kthread: Rely on HK_TYPE_DOMAIN for preferred affinity management"), the HK_TYPE_KTHREAD housekeeping cpumask may no longer be correct in showing the actual CPU affinity of kthreads that have no predefined CPU affinity. As the ipvs networking code is still using HK_TYPE_KTHREAD, we need to make HK_TYPE_KTHREAD reflect the reality. This patch series makes HK_TYPE_KTHREAD an alias of HK_TYPE_DOMAIN and uses RCU to protect access to the HK_TYPE_KTHREAD housekeeping cpumask. Julian plans to post a nf-next patch to limit the connections by using "conn_max" sysctl. With Simon Horman, they agreed that this is an old problem that we do not have a limit of connections and it is not a stopper for this patchset.
