Currently when we specify AF_INET6 when it is disabled, we will get
all routes.

For example, we can boot kernel with ipv6.disable=1 and try to get ipv6
routes:
$ ip -6 route show
default via 192.168.122.1 dev eth0  proto static  metric 100
192.168.122.0/24 dev eth0  proto kernel  scope link  src 192.168.122.141  metric 100

Here are ipv4 routes and this is unexpected behaviour.

Some qdiscs still lack a manpage, so listing them here is the only way
for a user to get to know them. For the others, this serves as an
overview of what is there.

Content was taken over from the dedicated manpage if available and
suitable, so there is definitely room for improvement at least by
adjusting it more to the context in which it is now. In case there
wasn't appropriate wording available, I tried to identify key aspects of
the given qdisc.

Commit 05325552 ('Support "ip link add help" for rtnl_link API') added a
check for specified help parameter. Though due to the place where it has
been added to, it is not possible anymore to force a given parameter to
be interpreted as interface name by prefixing it with 'dev '. Fix this
by forcing whatever follows 'dev' to be presumed as interface name.

Hi:

I found a formatting bug in the 4.1.1 ss command. The following line was
incorrectly output due to passing a negative length to printf() when
displaying the local address. In this instance hostapd does a "bind to
device" on cdreth0 and then does a udp "in address any" port 67 bind.
Please note the whitespace between the '*' and ' %cdreth0:67'

    'udp UNCONN 0 0 ** %cdreth0:67* *:* users:(("hostapd",pid=19241,fd=5))'

Attached is my patch for the bug fix, it might be prudent to add more
guard code looking for negative length format codes.

Sincerely, Mike

* "vti" and "vti6" tunnel modes added to ip-tunnel.8 manual page
* Added "hoplimit" terminology for IPv6
* Corrected usage line
* Minor language fix

This adds support for slightly less output than is normally provided by
'ip link show' and 'ip addr show'.  This is a bit better when you have a
host with lots of interfaces.  Sample output:

$ ip -br link show

the fd as soon as it is not used anymore. This way the inelegant goto
statements can be dropped, and the fd leak in non-error case is fixed as
well.
