Barebones start point for nexthops. Implementation for RTM commands,
notifications, management of rbtree for holding nexthops by id, and
kernel side data structures for nexthops and nexthop config.
Nexthops are maintained in an rbtree sorted by id. Similar to routes,
nexthops are configured per namespace using netns_nexthop struct added
to struct net.
Nexthop notifications are sent when a nexthop is added or deleted,
but NOT if the delete is due to a device event or network namespace
teardown (which also involves device events). Applications are
expected to use the device down event to flush nexthops and any
routes used by the nexthops.

New UAPI for nexthops as standalone objects:
- defines netlink ancillary header, struct nhmsg
- RTM commands for nexthop objects, RTM_*NEXTHOP,
- RTNLGRP for nexthop notifications, RTNLGRP_NEXTHOP,
- Attributes for creating nexthops, NHA_*
- Attribute for route specs to specify a nexthop by id, RTA_NH_ID.
The nexthop attributes and semantics follow the route and RTA ones for
device, gateway and lwt encap. Unique to nexthop objects are a blackhole
and a group which contains references to other nexthop objects. With the
exception of blackhole and group, nexthop objects MUST contain a device.
Gateway and encap are optional. Nexthop groups can only reference other
pre-existing nexthops by id. If the NHA_ID attribute is present that id
is used for the nexthop. If not specified, one is auto assigned.
Dump requests can include attributes:
- NHA_GROUPS to return only nexthop groups,
- NHA_MASTER to limit dumps to nexthops with devices enslaved to the
given master (e.g., VRF)
- NHA_OIF to limit dumps to nexthops using given device
nlmsg_route_perms in selinux code is updated for the new RTM comands.

When reset happens, the hardware reset should begin after the

Before Hardware's reset, it will wait for the driver to write
bit HCLGE_NIC_CMQ_ENABLE of register HCLGE_NIC_CSQ_DEPTH_REG
to 1, while the driver finishes its preparatory work will do that.
BTW, since some cases this register will be cleared, so it needs

I was really surprised that the IPv6 mtu exception followed by redirect
test was passing as nothing about the code suggests it should. The problem
is actually with the logic in the test script.
Fix the test cases as follows:
1. add debug function to dump the initial and redirect gateway addresses
for ipv6. This is shown only in verbose mode. It helps verify the
output of 'route get'.
2. fix the check_exception logic for the reset case to make sure that
for IPv4 neither mtu nor redirect appears in the 'route get' output.
For IPv6, make sure mtu is not present and the gateway is the initial
R1 lladdr.
3. fix the reset logic by using a function to delete the routes added by
initial_route_*. This format works better for the nexthop version of
the tests.
While improving the test cases, go ahead and ensure that forwarding is
disabled since IPv6 redirect requires it.
Also, runs with kernel debugging enabled sometimes show a failure with
one of the ipv4 tests, so spread the pings over longer time interval.
The end result is that 2 tests now show failures:
TEST: IPv6: mtu exception plus redirect [FAIL]
and the VRF version.
This is a bug in the IPv6 logic that will need to be fixed
separately. Redirect followed by MTU works because __ip6_rt_update_pmtu
hits the 'if (!rt6_cache_allowed_for_pmtu(rt6))' path and updates the
mtu on the exception rt6_info.
MTU followed by redirect does not have this logic. rt6_do_redirect
creates a new exception and then rt6_insert_exception removes the old
one which has the MTU exception.

inet: frags: avoid possible races at netns dismantle
This patch series fixes a race happening on netns dismantle with
frag queues. While rhashtable_free_and_destroy() is running,
concurrent timers might run inet_frag_kill() and attempt
rhashtable_remove_fast() calls. This is not allowed by
rhashtable logic.
Since I do not want to add expensive synchronize_rcu() calls
in the netns dismantle path, I had to no longer inline
netns_frags structures, but dynamically allocate them.
The ten first patches make this preparation, so that
the last patch clearly shows the fix.
As this patch series is not exactly trivial, I chose to
target 5.3. We will backport it once soaked a bit.

syszbot found an interesting use-after-free [1] happening
while IPv4 fragment rhashtable was destroyed at netns dismantle.
While no insertions can possibly happen at the time a dismantling
netns is destroying this rhashtable, timers can still fire and
attempt to remove elements from this rhashtable.
This is forbidden, since rhashtable_free_and_destroy() has
no synchronization against concurrent inserts and deletes.
Add a new fqdir->dead flag so that timers do not attempt
a rhashtable_remove_fast() operation.
We also have to respect an RCU grace period before starting
the rhashtable_free_and_destroy() from process context,
thus we use rcu_work infrastructure.
This is a refinement of a prior rough attempt to fix this bug :
https://marc.info/?l=linux-netdev&m=153845936820900&w=2
Since the rhashtable cleanup is now deferred to a work queue,
netns dismantles should be slightly faster.

fqdir will soon be dynamically allocated.
We need to reach the struct net pointer from fqdir,

by direct access to the new field.

(struct net *)->ieee802154_lowpan.fqdir will soon be a pointer, so make
sure lowpan_frags_ns_ctl_table[] does not reference init_net.
lowpan_frags_ns_sysctl_register() can perform the needed initialization
for all netns.
