Right now we're taking the stick-tables update lock for reads just for the sake of checking if the update index is past it or not. That's costly because even taking the read lock is sufficient to provoke a cache line write, while when under load or attack it's frequent that the update has not yet been propagated and wouldn't require anything. This commit brings a new field to the stksess, "seen", which is zeroed when the entry is updated, and set to one as soon as at least one peer starts to consult it. This way it will reflect that the entry must be updated again so that this peer can see it. Otherwise no update will be necessary. For now the flag is only set/reset but not exploited. A great care is taken to avoid writes whenever possible. |
