Also that there are now two ways to retrieve the DAT data via netlink. Kind regards, Sven
Hi, This is the fourth attempt to increase the DAT DHT timeout to reduce the amount of broadcasted ARP Replies. To increase the timeout only for DAT DHT entries added via DHT-PUT but not for any other entry in the DAT cache the DAT cache and DAT DHT concepts are first split into two separate hash tables (PATCH 1/2). PATCH 2/2 then increases the timeout for DAT DHT entries from 5 to 30 minutes. The motivation for this patchset is based on the observations made here: https://www.open-mesh.org/projects/batman-adv/wiki/DAT_DHCP_Snooping Regards, Linus --- Changelog v2: formerly: "batman-adv: Increase DHCP snooped DAT entry purge timeout in DHT" (https://patchwork.open-mesh.org/patch/17364/) - removed the extended timeouts flag in the DHT-PUT messages introduced in v1 again - removed DHCP dependency Changelog v3: formerly: "batman-adv: Increase purge timeout on DAT DHT candidates" https://patchwork.open-mesh.org/patch/17728/ - fixed the potential jiffies overflow and jiffies initialization issues by replacing the last_dht_update timeout variable with a split of DAT cache and DAT DHT into two separate hash tables -> instead of maintaining two timeouts in one DAT entry two DAT entries are created and maintained in their respective DAT cache and DAT DHT hash tables Changelog v4: - rebased to: acfc9a214d01695 ("batman-adv: genetlink: make policy common to family")
