With a current (5.1) kernel version, IPv6 exception routes can't be listed
(ip -6 route list cache) or flushed (ip -6 route flush cache). Kernel
support for this is being added back. Relevant net-next commits:
564c91f7e563 fib_frontend, ip6_fib: Select routes or exceptions dump from RTM_F_CLONED
ef11209d4219 Revert "net/ipv6: Bail early if user only wants cloned entries"

1e47b4837f3b ipv6: Dump route exceptions if requested
40cb35d5dc04 ip6_fib: Don't discard nodes with valid routing information in fib6_locate_1()
However, to allow the kernel to filter routes based on the RTM_F_CLONED
flag, we need to make sure this flag is always passed when we want cached
routes to be dumped, and we can also pass table and output interface
attributes to have the kernel filtering on them, if requested by the user.
Use the existing iproute_dump_filter() as a filter for the dump request in
iproute_flush(). This way, 'ip -6 route flush cache' works again.
v2: Instead of creating a separate 'filter' function dealing with
RTM_F_CACHED only, use the existing iproute_dump_filter() and get
table and oif kernel filtering for free. Suggested by David Ahern.

'ip netns exec' changes the current netns just before executing a child
process, and restores it after forking. This is needed if we're running
in batch or do_all mode.
Some cleanups must be done both in the parent and in the child: the
parent must restore the previous netns, while the child must reset any
VRF association.
Unfortunately, if do_all is set, the VRF are not reset in the child, and
the spawned processes are started with the wrong VRF context. This can
be triggered with this script:
# ip -b - <<-'EOF'
link add type vrf table 100
link set vrf0 up
link add type dummy
link set dummy0 vrf vrf0 up
netns add ns1
EOF
# ip -all -b - <<-'EOF'
vrf exec vrf0 true
netns exec setsid -f sleep 1h
EOF
# ip vrf pids vrf0
314 sleep
# ps 314
PID TTY STAT TIME COMMAND
314 ? Ss 0:00 sleep 1h
Refactor cmd_exec() and pass to it a function pointer which is called in
the child before the final exec. In the netns exec case the function just
resets the VRF and switches netns.
Doing it in the child is less error prone and safer, because the parent
environment is always kept unaltered.
After this refactor some utility functions became unused, so remove them.

When creating a new netns or executing a program into an existing one,
the unshare() or setns() calls will change the current netns.
In batch mode, this can run commands on the wrong interfaces, as the
ifindex value is meaningful only in the current netns. For example, this
command fails because veth-c doesn't exists in the init netns:
# ip -b - <<-'EOF'
netns add client
link add name veth-c type veth peer veth-s netns client
addr add 192.168.2.1/24 dev veth-c
EOF
Cannot find device "veth-c"
Command failed -:7
But if there are two devices with the same name in the init and new netns,
ip will build a wrong ll_map with indexes belonging to the new netns,
and will execute actions in the init netns using this wrong mapping.
This script will flush all eth0 addresses and bring it down, as it has
the same ifindex of veth0 in the new netns:
# ip addr

The same issue can be triggered by the netns exec subcommand with a
sligthy different script:
# ip netns add client
# ip -b - <<-'EOF'
netns exec client true
link add name veth0 type veth peer name veth1
link add name veth-ns type veth peer name veth0 netns client
link set veth0 down
address flush veth0
EOF
Fix this by adding two netns_{save,reset} functions, which are used
to get a file descriptor for the init netns, and restore it after
each batch command.
netns_save() is called before the unshare() or setns(),
while netns_restore() is called after each command.

When printing the actions, we avoid adding the trailing space after the

But for FR_ACT_TO_TBL nothing is printed. That means, we add double

# ip rule add priority 10 protocol 10 type 1
