Deleting single filter, deletes all the filters (apart from hashtable 800::) ... When I am trying to delete a single tc filter, it deleting all the filters with the same priority/preference. i.e. it is ignoring the handle specified. But, When I am deleting in hashtable 800: it is deleting only the specified filter. For example, following set of commands create a hashtable 15: and add 2 filters to it. tc filter add dev eth0 parent 1:0 prio 5 handle 15: protocol ip u32 divisor 256 tc filter add dev eth0 protocol ip parent 1: prio 5 handle 15:2:2 u32 ht 15:2: match ip src 10.0.0.2 flowid 1:10 tc filter add dev eth0 protocol ip parent 1: prio 5 handle 15:2:3 u32 ht 15:2: match ip src 10.0.0.3 flowid 1:10 Now following command DELETES ALL THE FILTERS, though it should only delete FILTER 15:2:3 ! tc filter del dev eth0 protocol ip parent 1: prio 5 handle 15:2:3 u32 O/p of tc filter show eth0 is this case is blank. As all filters are deleted. However, similar commands when executed for hashtable 800: is deleting only the specified filter tc filter add dev eth0 protocol ip parent 1: prio 5 handle 800:0:2 u32 ht 800:0: match ip src 10.0.0.2 flowid 1:10 tc filter add dev eth0 protocol ip parent 1: prio 5 handle 800:0:3 u32 ht 800:0: match ip src 10.0.0.3 flowid 1:10 tc filter del dev eth0 protocol ip parent 1: prio 5 handle 800:0:2 u32 Above mentioned command only deletes single filter. O/p of tc filter show eth0 is 2nd case is filter parent 1: protocol ip pref 5 u32 filter parent 1: protocol ip pref 5 u32 fh 800: ht divisor 1 filter parent 1: protocol ip pref 5 u32 fh 800::3 order 3 key ht 800 bkt 0 flowid 1:10 match 0a000003/ffffffff at 12 -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
