Subject: conntrackd: do not include conntrack ID in hashtable cmp
|
|
|
|
Depending on your conntrackd configuration, events might get lost,
|
|
leaving stuck entries in the cache forever. Skip checking the conntrack
|
|
ID to allow for lazy cleanup by when a new entry that is represented by
|
|
the same tuple is added.
