If get_rt_realms() fails, try to get a possible raw u32 realms
value for the u32 RTA_FLOW/FRA_FLOW attribute, as it might be
useful to directly configure the hex value itself. And only if
that fails, then bail out.
The source realm is provided in the upper u16 (mask: 0xffff0000)
and the destination realm through the lower u16 part (mask:
0x0000ffff). This can be useful for tc's bpf realm matcher, but
also a full hex/mask param can be provided already for matching
through iptables' --realm cmdline option, for example.

I've updated Jose's patch to make it slightly simpler (eg: calloc instead
of malloc+memset), and ported it to 4.2.0 which requires it as well, and
attached it to this e-mail.
I can confirm that with this patch 4.1.1 doesn't segfault on me anymore.
The commit message should be reworked I guess though everything's in it
and I didn't want to modify his description.
Can it be merged as-is or should I reword the commit message and reference
Jose as the fix reporter ? We should not let this bug live forever.
From: "j.ps@openmailbox.org" <j.ps@openmailbox.org>
Essentially all that is needed to get rid of this issue is the
addition of:
memset(u, 0, sizeof(*u));
after:
if (!(u = malloc(sizeof(*u))))
break;
Also patched some other situations (strcpy and sprintf uses) that
potentially produce the same results.

After eliminating the minor differences in both files which existed
solely because features/fixes were applied to only one of them and not
the other, the remaining differences were in function naming and error
messages. The latter is addressed by using the 'id' field of struct
link_util.
Fold both files into one in order to share common code and eliminate the
chance of having fixes/enhancements applied to only one of them.

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 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.
