v3: - added _S suffix to NEIGH_ENTRY_MAX_AGING_TIME (patch #2) - Added Reported-at tag (patch #4)
v2: - rebased against master - turned 'ageing' -> 'aging' - further details of v1 -> v2 respin has been added to each patch The series is composed of the following patches: #1: Expires is modified in different contexts (revalidator, pmd-rx, bfd-tx). It's probably not very racy for many reasons, but it seems a good idea to use an atomic here (especially with the introduction of #3). #2: Introduces the possibility to set and read the entries timeout. It's useful for debugging purpose. Includes a self-test. #3: While performing some tests I noticed unstable timeouts (more visible when the ageing time is low) during nd snoop. It turned out to be a problem of revalidation. Additional details can be found in the commit description. #4: Fixes a use case in which the tnl neigh entry never gets updated (further details in the commit message). Includes a self-test. The use case fixed in #4 could be fixed relaxing the check in tnl_arp_snoop(), allowing to snoop ARP requests as well, but such approach could add unneeded entries in the cache. Paolo Valerio (4): Native tunnel: Read/write expires atomically. Native tunnel: Add tnl/neigh/aging command. Native tunnel: Do not refresh the entry while revalidating. Tunnel: Snoop ingress packets and update neigh cache if needed.
