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.

Code to parse and export this tuneable via netlink is already present in
sched_fq.c of the kernel, so not making it accessible for users would be
a waste of resources.

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 0532555 ('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
This patch adds support for bridge vlan_protocol.
Example:
$ ip link set br0 type bridge vlan_protocol 802.1ad
$ ip -d link show br0

UP mode DEFAULT group default qlen 1000

bridge forward_delay 0 hello_time 200 max_age 2000 ageing_time 30000
stp_state 0 priority 32768 vlan_filtering 0 vlan_protocol 802.1ad

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
lo UNKNOWN 00:00:00:00:00:00 <LOOPBACK,UP,LOWER_UP>
p2p1 UP 08:00:27:ee:0b:3b <BROADCAST,MULTICAST,UP,LOWER_UP>

p8p1 DOWN 08:00:27:dc:d8:ca <NO-CARRIER,BROADCAST,MULTICAST,UP>
p9p1 UP 08:00:27:76:d9:75 <BROADCAST,MULTICAST,UP,LOWER_UP>

My previous patch 5950ba9 ("lib/namespace: don't leak fd in error case")
was a step in the wrong direction. Instead of closing the opened file
descriptor in error case only, follow a better approach here and close
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.

* Improve manual page synopsis and built-it help
* Use full subcommand names (e.g. 'address' and 'maddress')
* Specify when IPv4, IPv6 or both are affected
* Add lifetimes, home and nodad
* Remove any remaining excess spaces
Commit 43d29f7 substantially improves generated ip-address.8 instead of
ip-address.8.in and commit e419f2d removes the generated one losing the
improvements entirely. This commit recovers the lost changes, adapts
them to the current manual page and adds more man page and help
improvements.

This was working before, but only if realloc a) succeeded and b) did not
move the buffer to a different location. ''**buf = **new_buf' then
writes the value of *new_buf's first field into that of *buf.

This patch implements support for the IFLA_BR_VLAN_FILTERING attribute
in iproute2 so it can enable/disable vlan_filtering.
Example:
$ ip link set br0 type bridge vlan_filtering 1
$ ip -d link show br0

UP mode DEFAULT group default
link/ether 08:00:27:ea:07:38 brd ff:ff:ff:ff:ff:ff promiscuity 0
