If the kernel has +similar routes which are candidates for the replacement, it's hard for +NM to guess which one of those is being replaced (as the kernel doesn't +have a "route ID" or similar field to indicate it). Moreover, the kernel +might choose to replace a route that we don't have on cache, so we know +nothing about it. + +It is important to note that we cannot just discard Netlink messages of +routes that we don't track if they has the NLM_F_REPLACE. For example, +if we are tracking a route with proto=static, we might receive a replace +message, changing that route to proto=other_proto_that_we_dont_track. We +need to process that message and remove the route from our cache. + +As NM doesn't know what route is being replaced, trying to guess will +lead to errors that will leave the cache in an inconsistent state. +Because of that, it just do a cache resync for the routes. + +For IPv4 there was an optimization to this: if we don't have in the +cache any route candidate for the replacement there are only 2 possible +options: either add the new route to the cache or discard it if we are +not interested on it. We don't need a resync for that. + +This commit is extending that optimization to IPv6 routes. There is no +reason why it shouldn't work in the same way than with IPv4. This +optimization will only work well as long as we find potential candidate +routes in the same way than the kernel (comparing the same fields). NM +calls to this "comparing by WEAK_ID". But this can also happen with IPv4 +routes. + +It is worth it to enable this optimization because there are routing +daemons using custom routing protocols that makes tens or hundreds of +updates per second. If they use NLM_F_REPLACE, this caused NM to do a +resync hundreds of times per second leading to a 100% CPU usage: +https://issues.redhat.com/browse/RHEL-26195 + +An additional but smaller optimization is done in this commit: if we +receive a route message for routes that we don't track AND doesn't have +the NLM_F_REPLACE flag, we can ignore the entire message, thus avoiding +the memory allocation of the nmp_object. That nmp_object was going to be +ignored later, anyway, so better to avoid these allocations that, with +the routing daemon of the above's example, can happen hundreds of times +per second. + +With this changes, the CPU usage doing `ip route replace` 300 times/s +drops from 100% to 1%. Doing `ip route replace` as fast as possible, +without any rate limitting, still keeps NM with a 3% CPU usage in the +system that I have used to test. + +(cherry picked from commit 4d426f581de402e0aebd2ab273ff6649a0a6fee6) +(cherry picked from commit 15ffa8ec6ff7bf43ed1eb123c0d419d6fab8b268) +--- + src/libnm-platform/nm-linux-platform.c | 69 ++++++++++++++++---------- + src/libnm-platform/nmp-object.c | 22 +++++--- + 2 files changed, 57 insertions(+), 34 deletions(-) + +diff --git a/src/libnm-platform/nm-linux-platform.c b/src/libnm-platform/nm-linux-platform.c +index 9ecac2d9b3..5b595a9b71 100644 +--- a/src/libnm-platform/nm-linux-platform.c ++++ b/src/libnm-platform/nm-linux-platform.c +@@ -3903,6 +3903,34 @@ _new_from_nl_addr(const struct nlmsghdr *nlh, gboolean id_only) + return g_steal_pointer(&obj); + } + ++static gboolean ++ip_route_is_tracked(guint8 proto, guint8 type) ++{ ++ if (proto > RTPROT_STATIC && !NM_IN_SET(proto, RTPROT_DHCP, RTPROT_RA)) { ++ /* We ignore certain rtm_protocol, because NetworkManager would only ever ++ * configure certain protocols.
