[Devel] [PATCH RH7 0/3] netfilter: nf_tables: switch read path to rcu

We have a customer claiming that iptables-nft takes too long to list rules from container on big systems. So we remove global nfnl_lock from read code paths and replace it with rcu to improve perfomane for that case. https://virtuozzo.atlassian.net/browse/PSBM-150147 Signed-off-by: Pavel Tikhomiro

[Devel] [PATCH RH7 2/3] netfilter: nf_tables: fix oops during rule dump

From: Florian Westphal We can oops in nf_tables_fill_rule_info(). Its not possible to fetch previous element in rcu-protected lists when deletions are not prevented somehow: list_del_rcu poisons the ->prev pointer value. Before rcu-conversion this was safe as dump operations did hold nfnetlink

[Devel] [PATCH RH7 3/3] netfilter: nf_tables: use list_entry_rcu in nft_do_chain

We already use list_for_each_entry_continue_rcu two lines below, it is thus logical to also use list_entry_rcu there. https://virtuozzo.atlassian.net/browse/PSBM-150147 Signed-off-by: Pavel Tikhomirov --- net/netfilter/nf_tables_core.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff

[Devel] [PATCH RH7 1/3] netfilter: nf_tables: use call_rcu in netlink dumps

From: Florian Westphal We can make all dumps and lookups lockless. Dumps currently only hold the nfnl mutex on the dump request itself. Dumps can span multiple syscalls, dump continuation doesn't acquire the nfnl mutex anywhere, i.e. the dump callbacks in nf_tables already use rcu and never rely

[Devel] [PATCH vz9 9/9] ms/x86/reboot: VMCLEAR active VMCSes before emergency reboot

From: Sean Christopherson VMCLEAR active VMCSes before any emergency reboot, not just if the kernel may kexec into a new kernel after a crash. Per Intel's SDM, the VMX architecture doesn't require the CPU to flush the VMCS cache on INIT. If an emergency reboot doesn't RESET CPUs, cached VMCSes
