As a system admin I occasionally want to be able to check that all
interfaces has a name in DNS or /etc/hosts file.
Signed-off-by: Sami Kerola <kerolasa@iki.fi>

Example:

$ ss state established \( sport = :4060  or sport = :4061 or sport = :4062  or sport = :4063 or sport = :4064  or sport = :4065 or sport = :4066  or sport = :4067 \)  > /dev/null
Aborted

In the example above ssfilter_bytecompile(...) will return (int)136.
char l1 = 136; means -120 which will result in a negative number
being passed to malloc at misc/ss.c:913.

Simply declare l1 and l2 as integers to avoid the char overflow.

This is one of the issues originally reported in http://bugs.debian.org/511720

Fix the same problem in other code paths as well (thanks to Eric Dumazet).

As both linux kernel and function ipaddrlabel_modify use unsigned int for
label. We should also use unsigned int value when print addrlabel in case of
misunderstanding.

Conflicts:
	tc/q_fq.c

There are two global variables in tc/tc_class.c:
__u32 filter_qdisc;
__u32 filter_classid;

These are not re-initialized for each line received in -batch mode:
class show dev eth0 parent 1: classid 1:1
class show dev eth0 parent 1: classid 1:1
Error: duplicate "classid": "1:1" is the second value.

This patch fixes the issue by initializing the two globals when we
enter print_class().

The kernel already supports it, so add the support

macvtap and vti were missing.
Signed-off-by: Nicolas Dichtel <nicolas.dichtel@6wind.com>

ip xfrm considers that the user-defined mark is "any" as soon as
(mark.v & mark.m == 0), which prevents from specifying non-wildcard
marks that include the value 0 (typically 0/0xffffffff).

Yet, matching exactly mark 0 is useful for instance to separate
vti policies from global policies.

Always configure the user mark if mark.m != 0.

TCA_HTB_DIRECT_QLEN attribute is supported since linux-3.10

HTB classes use an internal pfifo queue, which limit was not reported
by tc, and value inherited from device tx_queue_len at setup time.

With this patch, tc displays the value and can change it.
