Biederman says: ==================== net: Pass net through ip fragmention This is the next installment of my work to pass struct net through the output path so the code does not need to guess how to figure out which network namespace it is in, and ultimately routes can have output devices in another network namespace. This round focuses on passing net through ip fragmentation which we seem to call from about everywhere. That is the main ip output paths, the bridge netfilter code, and openvswitch. This has to happend at once accross the tree as function pointers are involved. First some prep work is done, then ipv4 and ipv6 are converted and then temporary helper functions are removed. ==================== Acked-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | When I did the conversion to rhashtable I missed the required locking of one important user of the vlan list - br_get_link_af_size_filtered() which is called: br_ifinfo_notify() -> br_nlmsg_size() -> br_get_link_af_size_filtered() and the notifications can be sent without holding rtnl. Before this conversion the function relied on using rcu and since we already use rcu to destroy the vlans, we can simply migrate the list to use the rcu helpers.

| | | | | | | | | | | | | | | | | | | | | | When a new port is being added we need to make vlgrp available after rhashtable has been initialized and when removing a port we need to flush the vlans and free the resources after we're sure noone can use the port, i.e. after it's removed from the port list and synchronize_rcu is executed.

| | | | | | | | | | | | | | | | | | | | | | One obvious way to converge more code (which was also used by the previous vlan code) is to move pvid inside net_bridge_vlan_group.

|/ | | | | | | | | | As Stephen pointed out the default initial size is more than we need, so let's start small (4 elements, thus nelem_hint = 3). Also limit the hash locks to the number of CPUs as we don't need any write-side scaling and this looks like the minimum.

The main goal of this batch is to avoid recurrent lookups for the netns pointer, that happens over and over again in our Netfilter/IPVS code. The idea consists of passing netns pointer from the hook state to the relevant functions and objects where this may be needed. You can find more information on the IPVS updates from Simon Horman's commit merge message: c3456026adc0 ("Merge tag 'ipvs2-for-v4.4' of https://git.kernel.org/pub/scm/linux/kernel/git/horms/ipvs-next").
