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
