Vlad Buslov cb83101626 tc: remove duplicated NEXT_ARG_FWD() in parse_ct()
Function parse_ct() manually calls NEXT_ARG_FWD() after
parse_action_control_dflt(). This is redundant because
parse_action_control_dflt() modifies argc and argv itself. Moreover, such
implementation parses out any following actions option. For example, adding
action ct with cookie errors:

$ sudo tc actions add action ct cookie 111111111111
Bad action type 111111111111
Usage: ... gact <ACTION> [RAND] [INDEX]
Where:  ACTION := reclassify | drop | continue | pass | pipe |
                  goto chain <CHAIN_INDEX> | jump <JUMP_COUNT>
        RAND := random <RANDTYPE> <ACTION> <VAL>
        RANDTYPE := netrand | determ
        VAL : = value not exceeding 10000
        JUMP_COUNT := Absolute jump from start of action list
        INDEX := index value used

With fix:

$ sudo tc actions add action ct cookie 111111111111
$ sudo tc actions list action ct
total acts 1

        action order 0: ct zone 0 pipe
         index 1 ref 1 bind 0

Andrea Claudi e047ca988f tc: fix segmentation fault on gact action
tc segfaults if gact action is used without action or index:

$ ip link add type dummy
$ tc actions add action pipe index 1
$ tc filter add dev dummy0 parent ffff: protocol ip \
  pref 10 u32 match ip src 127.0.0.2 flowid 1:10 action gact
Segmentation fault

We expect tc to fail gracefully with an error message.

This happens if gact is the last argument of the incomplete
command. In this case the "gact" action is parsed, the macro
NEXT_ARG_FWD() is executed and the next matches() crashes
because of null argv pointer.

To avoid this, simply use NEXT_ARG() instead.

With this change in place:

$ ip link add type dummy
$ tc actions add action pipe index 1
$ tc filter add dev dummy0 parent ffff: protocol ip \
  pref 10 u32 match ip src 127.0.0.2 flowid 1:10 action gact
Command line is not complete. Try option "help"

David Dai 1157a6fc36 iproute2-next: police: support 64bit rate and peakrate in tc utility

100 Gbits per second bandwidth. Currently htb already supports 64bit rate
in tc utility. However police action rate and peakrate are still limited
to 32bit value (upto 32 Gbits per second). Taking advantage of the 2 new
attributes TCA_POLICE_RATE64 and TCA_POLICE_PEAKRATE64 from kernel,
tc can use them to break the 32bit limit, and still keep the backward
binary compatibility.

Ido Schimmel 395370035e tc: Fix block-handle support for filter operations
The revert of batchsize accidently reverted more than it should
and broke shared block functionality.  Fix this by restoring the
original functionality.

To reproduce:

	dst_ip 192.0.2.0/24 action drop
Unknown filter "block", hence option "10" is unparsable

ETF Qdisc currently checks for a socket with SO_TXTIME socket option. If
either is not present, the packet is dropped. In the future commits, we
want other Qdiscs to add packet with launchtime to the ETF Qdisc. Also,
there are some packets (e.g. ICMP packets) which may not have a socket
associated with them.  So, add an option to skip this check.

Andrea Claudi 6bc13e4a20 tc: util: constrain percentage in 0-100 interval
parse_percent() currently allows to specify negative percentages
or value above 100%. However this does not seems to make sense,
as the function is used for probabilities or bandiwidth rates.

Moreover, using negative values leads to erroneous results
(using Bernoulli loss model as example):

$ ip link add test type dummy
$ ip link set test up
$ tc qdisc add dev test root netem loss gemodel -10% limit 10
$ tc qdisc show dev test
qdisc netem 800c: root refcnt 2 limit 10 loss gemodel p 90% r 10% 1-h 100% 1-k 0%

Using values above 100% we have instead:

$ ip link add test type dummy
$ ip link set test up
$ tc qdisc add dev test root netem loss gemodel 140% limit 10
$ tc qdisc show dev test
qdisc netem 800f: root refcnt 2 limit 10 loss gemodel p 40% r 60% 1-h 100% 1-k 0%

This commit changes parse_percent() with a check to ensure
percentage values stay between 1.0 and 0.0.
parse_percent_rate() function, which already employs a similar
check, is adjusted accordingly.

With this check in place, we have:

$ ip link add test type dummy
$ ip link set test up
$ tc qdisc add dev test root netem loss gemodel -10% limit 10
Illegal "loss gemodel p"
