Subject: [PATCH] libnetlink: Fix memory leak in __rtnl_talk_iov()
If `__rtnl_talk_iov` fails then callers are not expected to free `answer`.
Currently if `NLMSG_ERROR` was received with an error then the netlink
buffer was stored in `answer`, while still returning an error
This leak can be observed by running this snippet over time.
This triggers an `NLMSG_ERROR` because for each neighbour update, `ip`
will try to query for the name of interface 9999 in the wrong netns.
(which in itself is a separate bug)
set -e
ip netns del test-a || true
ip netns add test-a
ip netns del test-b || true
ip netns add test-b
ip -n test-a netns set test-b auto
ip -n test-a link add veth_a index 9999 type veth \
peer name veth_b netns test-b
ip -n test-b link set veth_b up
ip -n test-a monitor link address prefix neigh nsid label all-nsid \
> /dev/null &
monitor_pid=$!
clean() {
kill $monitor_pid
ip netns del test-a
ip netns del test-b
}
trap clean EXIT
while true; do
ip -n test-b neigh add dev veth_b 1.2.3.4 lladdr AA:AA:AA:AA:AA:AA
ip -n test-b neigh del dev veth_b 1.2.3.4
done

Using macro NEXT_ARG_FWD does not validate argc.
Use macro NEXT_ARG which validates argc while parsing args
in the same loop iteration.

This patch is to fix the issue where there is no error return
when large value of parent ID is being used. The return value by
stroul() is unsigned long int. Hence the datatype for maj and min

Subject: [PATCH] xfrm: prepare state offload logic to set mode
The offload in xfrm state requires to provide device and direction
in order to activate it. However, in the help section, device and
direction were displayed as an optional.
As a preparation to addition of packet offload, let's fix the help
section and refactor the code to be more clear.
