The existing code tries to kill many birds with one stone: Handling binding of actions to filters, new actions and replacing of action attributes. A simple test case to illustrate: XXXX moja@fe1:~$ sudo tc actions add action drop index 12 moja@fe1:~$ actions get action gact index 12 action order 1: gact action drop random type none pass val 0 index 12 ref 1 bind 0 moja@fe1:~$ sudo tc actions replace action ok index 12 moja@fe1:~$ actions get action gact index 12 action order 1: gact action drop random type none pass val 0 index 12 ref 2 bind 0 XXXX The above shows the refcounf being wrongly incremented on replace. There are more complex scenarios with binding of actions to filters that i am leaving out that didnt work as well... Signed-off-by: Jamal Hadi Salim Signed-off-by: David S.
