Jamal Hadi Salim 9e71352581 tc actions: Improved batching and time filtered dumping
dump more than TCA_ACT_MAX_PRIO actions per batch when the kernel
supports it.

Introduced keyword "since" for time based filtering of actions.
Some example (we have 400 actions bound to 400 filters); at
installation time. Using updated when tc setting the time of
interest to 120 seconds earlier (we see 400 actions):
prompt$ hackedtc actions ls action gact since 120000| grep index | wc -l
400

go get some coffee and wait for > 120 seconds and try again:

prompt$ hackedtc actions ls action gact since 120000 | grep index | wc -l
0

Lets see a filter bound to one of these actions:
....
filter pref 10 u32
filter pref 10 u32 fh 800: ht divisor 1
filter pref 10 u32 fh 800::800 order 2048 key ht 800 bkt 0 flowid 1:10  (rule hit 2 success 1)
  match 7f000002/ffffffff at 12 (success 1 )
    action order 1: gact action pass
     random type none pass val 0
     index 23 ref 2 bind 1 installed 1145 sec used 802 sec
    Action statistics:
    Sent 84 bytes 1 pkt (dropped 0, overlimits 0 requeues 0)
    backlog 0b 0p requeues 0
...

that coffee took long, no? It was good.

Now lets ping -c 1 127.0.0.2, then run the actions again:
prompt$ hackedtc actions ls action gact since 120 | grep index | wc -l
1

More details please:
prompt$ hackedtc -s actions ls action gact since 120000

    action order 0: gact action pass
     random type none pass val 0
     index 23 ref 2 bind 1 installed 1270 sec used 30 sec
    Action statistics:
    Sent 168 bytes 2 pkt (dropped 0, overlimits 0 requeues 0)
    backlog 0b 0p requeues 0

And the filter?
filter pref 10 u32
filter pref 10 u32 fh 800: ht divisor 1
filter pref 10 u32 fh 800::800 order 2048 key ht 800 bkt 0 flowid 1:10  (rule hit 4 success 2)
  match 7f000002/ffffffff at 12 (success 2 )
    action order 1: gact action pass
     random type none pass val 0
     index 23 ref 2 bind 1 installed 1324 sec used 84 sec
    Action statistics:
    Sent 168 bytes 2 pkt (dropped 0, overlimits 0 requeues 0)
    backlog 0b 0p requeues 0

How to compile this.
--------------------
1. libdbm

arpd needs to have the db4 development libraries. For Debian
users this is the package with a name like libdb4.x-dev.
DBM_INCLUDE points to the directory with db_185.h which
is the include file used by arpd to get to the old format Berkeley
database routines.  Often this is in the db-devel package.

2. make

The makefile will automatically build a Config file which
contains whether or not ATM is available, etc.

3. To make documentation, cd to doc/ directory , then
   look at start of Makefile and set correct values for
   PAGESIZE=a4		, ie: a4 , letter ...	(string)
   PAGESPERPAGE=2	, ie: 1 , 2 ...		(numeric)
   and make there. It assumes, that latex, dvips and psnup
   are in your path.

4. This package includes matching sanitized kernel headers because
   the build environment may not have up to date versions. See Makefile
   if you have special requirements and need to point at different
   kernel include files.
