Ondrej Zajicek (work) e818f16448 Netlink: Enable strict checking for KRT dumps ... Add strict checking for netlink KRT dumps to avoid PMTU cache records from FNHE table dump along with KRT. Linux Kernel added FNHE table dump to the netlink API in patch: 8d3b68cd37.1561131177.git.sbrivio@redhat.com/ Therefore, since Linux 5.3 these route cache entries are dumped together with regular routes during periodic KRT scans, which in some cases may be huge amount of useless data. This can be avoided by using strict checking for netlink dumps: https://lore.kernel.org/netdev/20181008031644.15989-1-dsahern@kernel.org/ The patch mitigates the risk of receiving unknown and potentially large number of FNHE records that would block BIRD I/O in each sync. There is a known issue caused by the GRE tunnels on Linux that seems to be creating one FNHE record for each destination IP address that is routed through the tunnel, even when the PMTU equals to GRE interface MTU. Thanks to Tomas Hlavacek for the original patch.		2022-01-14 21:53:40 +01:00
