IPv6 uses the same data struct for both control plane (FIB entries) and
data path (dst entries). This struct has elements needed for both paths
adding memory overhead and complexity (taking a dst hold in most places
but an additional reference on rt6i_ref in a few). Furthermore, because
of the dst_alloc tie, all FIB entries are allocated with GFP_ATOMIC.
This patch set separates FIB entries from dst entries, better aligning
IPv6 code with IPv4, simplifying the reference counting and allowing
FIB entries added by userspace (not autoconf) to use GFP_KERNEL. It is
first step to a number of performance and scalability changes.
The end result of this patch set:
- FIB entries (fib6_info):
/* size: 208, cachelines: 4, members: 25 */
/* sum members: 207, holes: 1, sum holes: 1 */
- dst entries (rt6_info)
/* size: 240, cachelines: 4, members: 12 */
Versus the the single rt6_info struct today for both paths:
/* size: 320, cachelines: 5, members: 28 */
This amounts to a 35% reduction in memory use for FIB entries and a
25% reduction for dst entries.
With respect to locking FIB entries use RCU and a single atomic
counter with fib6_info_hold and fib6_info_release helpers to manage
the reference counting. dst entries use only the traditional dst
refcounts with dst_hold and dst_release.
FIB entries for host routes are referenced by inet6_ifaddr and
ifacaddr6. In both cases, additional holds are taken -- similar to
what is done for devices.
This set is the first of many changes to improve the scalability of the
IPv6 code. Follow on changes include:
- consolidating duplicate fib6_info references like IPv4 does with
duplicate fib_info
- moving fib6_info into a slab cache to avoid allocation roundups to
power of 2 (the 208 size becomes a 256 actual allocation)
- Allow FIB lookups without generating a dst (e.g., most rt6_lookup
users just want to verify the egress device). Means moving dst
allocation to the other side of fib6_rule_lookup which again aligns
with IPv4 behavior
- using separate standalone nexthop objects which have performance
benefits beyond fib_info consolidation
At this point I am not seeing any refcount leaks or underflows, no
oops or bug_ons, or warnings from kasan, so I think it is ready for
others to beat up on it finding errors in code paths I have missed.

Move logic of fib_convert_metrics into dst_metrics_convert. This allows
the code that converts netlink attributes into metrics struct to be
re-used in a later patch by IPv6.
This is mostly a code move only; it involvesthe following changes to
variable names:
- fi->fib_net becomes net
- fc_mx and fc_mx_len are passed as inputs pulled from cfg
- metrics array is passed as an input from fi->fib_metrics->metrics

A later patch removes rt6i_table from rt6_info. Save the ipv6
table for a VRF in net_vrf. fib tables can not be deleted so
no reference counting or locking is required.

Pass net namespace to fib6_update_sernum. Can not be marked const
as fib6_new_sernum will change ipv6.fib6_sernum.

Introduce fib6_nh structure and move nexthop related data from
rt6_info and rt6_info.dst to fib6_nh. References to dev, gateway or
lwtstate from a FIB lookup perspective are converted to use fib6_nh;
datapath references to dst version are left as is.

Similar to IPv4, add fib metrics to the fib struct, which at the moment
is rt6_info. Will be moved to fib6_info in a later patch.
Copy metrics into dst by reference using refcount.

Cc: davem, idosch, roopa, eric.dumazet, weiwan, kafai, yoshfuji, David Ahern
Add expires to rt6_info for FIB entries, and add fib6 helpers to
manage it. Data path use of dst.expires remains.

ip6_null_entry will stay a dst based return for lookups that fail to
match an entry.
Add a new fib6_null_entry which constitutes the root node and leafs
for fibs.

ip6_pol_route_lookup is the lookup function for ip6_route_lookup and
rt6_lookup. At the moment it returns either a reference to a FIB entry
or a cached exception. To move FIB entries to a separate struct, this
lookup function need to convert FIB entries to an rt6_info that is
returned to the caller.

Use bool to hold requests for certain dst settings when a FIB entry
is converted to a dst.

Refactor dst_neigh_lookup and create a new function that takes the
gateway and device. Since rt6_get_dflt_router returns a FIB entry,
change ndisc_router_discovery to use the new ip6_neigh_lookup.

Most FIB entries can be added using memory allocated with GFP_KERNEL.
Add gfp_flags to ip6_route_add and addrconf_dst_alloc. Code paths that
can be reached from the packet path (e.g., ndisc and autoconfig) or
atomic notifiers use GFP_ATOMIC; paths from user context (adding
addresses and routes) use GFP_KERNEL.

IPv6 FIB will only contain FIB entries with exception routes added to
the FIB entry. Remove CACHE and dst checks from fib6 add and delete since
they can never happen once the data type changes.
Fixup the lookup functions to use a f6i name for fib lookups and retain
the current rt name for return variables.

This makes the networking core depend upon CONFIG_INET.
You will have to untangle this somehow before your final submission.
Probably with an inline helper in the non-INET case that always
returns TCP_CA_UNSPEC.

Is this change really OK all by itself?
Sure, you fix up the vrf code operating on such 'rt6' objects to
not dereference the ->rt6i_table.
But any other code whatsoever that looks at this rt6 object (dumping,
other operations in the ipv6 stack data or control plane, etc.) can
legitimately expect always to see a non-NULL value here.
I really don't see how this can be OK and leave your patch series
properly bisectable.
Thanks.

This seems to change behavior.
In the old code, the dst error value is propagated from 'ort' into 'rt'.
Here you set it to zero and that's it.
Is it set somewhere else?
I don't think you can assume that all routes that go via this copy
path are not reject routes or other kinds that need the error code
set, if that is what you were thinking.
Thanks.

Hard to interpret what you mean in that second paragraph.
Do you mean that this invariant holds after patch #19 only? Then you
really can't make these simplifications until then in order to keep
the patch series bisectable.
Otherwise you mean something else and I'd like to know what that is.
Either way, the commit message wording could be improved since even
a dolt like me got confused :-)

good point. Perhaps net/ipv4/metrics.c is a better place for it given
that ipv4/ipv6 common code appears to be under net/ipv4. I need to play
with the config build permutations.

should. When you look at references to rt6i_table the only one for the
data path is changing sernum when inserting an exception. Exceptions are
not relevant for this special VRF dst as it is used for an internal
redirection before packets leave the box.

But if you want me to be extra cautious I can leave the rt6i_table
setting and remove it in patch 20 (remove unneeded rt6_info elements).

Only REJECT routes have dst->error set and the only place that happens
is ip6_route_info_create:
$ egrep -r 'dst.error = |dst->error = ' include net
net/core/dst.c: dst->error = 0;
net/ipv6/route.c: rt->dst.error = -EINVAL;
net/ipv6/route.c: rt->dst.error = -EACCES;
net/ipv6/route.c: rt->dst.error = (cfg->fc_type == RTN_THROW) ? -EAGAIN
net/ipv6/route.c: rt->dst.error = ort->dst.error;
You cut the context, so I will add the diff here:
+static void ip6_rt_init_dst_reject(struct rt6_info *rt, struct rt6_info
*ort)
+{
+ rt->dst.error = ip6_rt_type_to_error(ort->fib6_type);
+
+ switch (ort->fib6_type) {
+ case RTN_BLACKHOLE:
+ rt->dst.output = dst_discard_out;
+ rt->dst.input = dst_discard;
+ break;
+ case RTN_PROHIBIT:
+ rt->dst.output = ip6_pkt_prohibit_out;
+ rt->dst.input = ip6_pkt_prohibit;
+ break;
+ case RTN_THROW:
+ case RTN_UNREACHABLE:
+ default:
+ rt->dst.output = ip6_pkt_discard_out;
+ rt->dst.input = ip6_pkt_discard;
+ break;
+ }
+}
+
+static void ip6_rt_init_dst(struct rt6_info *rt, struct rt6_info *ort)
+{
+ if (ort->rt6i_flags & RTF_REJECT) {
+ ip6_rt_init_dst_reject(rt, ort);
+ return;
+ }
+
+ rt->dst.error = 0;
+ rt->dst.output = ip6_output;
+
+...
So for reject routes we have the above helper which is basically a code
move from ip6_route_info_create.
For non-reject routes dst.error is 0 which is the rest of ip6_rt_init_dst.

My bad, thanks for explaining things to me. The flag bit test above
completely escaped my eyes for some reason. :)

By the 20th iteration the description of the last few patches got a
little thin. ;-)
The point of patches 1-18 is to make as small a change per patch that
leads up to patch 19 being nothing more than s/rt6_info/fib6_info/ is
select data paths. A struct rename and all of the related code paths
makes for a huge patch.
Anyways, because rt6_info is used for both FIB and dst the lookup
functions can overload the rt6_info variable usually called 'rt'. This
patch introduces a new 'f6i' variable name for the result of the FIB
lookup and keeps 'rt' as the dst based return variable. 'f6i' becomes a
fib6_info in patch 19 which is why it is introduced as 'struct rt6_info
*f6i' now; avoids the additional churn in patch 19.

This I understand. :)
Adjust this commit message to include some of this text and I'm
happy.
BTW, I love patch #20, those edits must have been fun to make :-)

No, it's not necessary if it is really an isolated object like this.

My understanding is that after your whole patch series, sibling routes
will still have their own fib6_info. Does it make sense to make this
fib6_nh as an array in fib6_info so that sibling routes will share
fib6_info but will have their own fib6_nh as a future improvement? It
matches ipv4 behavior. And I think it will make the sibling route
handling code easier?

I was wondering if we need to retain the above logic. It makes sure
dst.expires gets synced to its "parent" route. But it might be hard
because after your change, we can no longer use rt->from to refer to
the "parent".

Could you help delete rt6_remove_exception_rt() function? I don't
think it is used anymore.

Here "rt" should also be renamed to "f6i"? Probably need to update
for_each_fib6_node_rt_rcu() macro to use f6i instead of rt.

I was not planning to. IPv6 allowing individual nexthops to be added and
deleted is very convenient. I do agree the existing sibling route
linkage makes the code much more complicated than it needs to be.
After this set, I plan to send patches for nexthops as separate objects
- which will have an impact on how multipath routes are done. With
nexthop objects there will be 1 prefix route pointing to a nexthop
object that is multipath (meaning it points in turn to a series of
nexthop objects). This provides the simplification (no sibling linkage)
without losing the individual nexhtop add / delete option.

As I understand it, the FIB entries are cloned into pcpu, uncached and
exception routes. We should never have an rt6_info that ever points back
more than 1 level -- ie., the dst rt6_info points to a from representing
the original FIB entry.
After my change 'from' will still point to the FIB entry as a fib6_info
which has its own expires.
When I looked this code I was really confused. At best, the for loop
above sets rt0->dst.expires to some value based on the 'from' but then
the very next line calls dst_set_expires with the passed in timeout value.

It is still used by ip6_negative_advice, ip6_link_failure and
ip6_del_cached_rt. It can be made static; will fix.
The rest of your comments for this patch are renaming rt to f6i. My
thought is to follow up with another patch that does the rename of rt to
f6i for all fib6_info. Given how large this change is already I did not
want to add extra diffs for that. If there is agreement to fold that
part in now, I can do it.

understood. And fib6_age() is using fib6_check_expired() and
rt6_age_exceptions() is checking rt->dst.expires which I think is
correct.

Did fib6_info_alloc() already bump the refcnt? Why
another fib6_info_hold() is needed? Comment would be
useful here.

The extra release corresponds to the above fib6_info_hold()?

My understanding is, the rt0 first inherits the expires from its rt0->from.
The following dst_set_expires() set a new timeout if the new timeout
is earlier than the existing expires. I think it is essentially
taking a min.
One question, would avoid taking the min cause the rt0 somehow
have a longer expires than its parent (or f6i after this series)?

The alloc does set it to 1; the extra bump here is because of the
ifa->rt assignment.
Without the additional reference, deleting the route would cause rt to
be freed, yet ifa has a reference to it. I did not want to wade into
changes to the accounting for this set, though I do think it needs to be
revisited.
I'll take another look at whether this is really needed.

I believe the current logic expands to:
static inline void rt6_update_expires(struct rt6_info *rt0, int timeout)
{
if (!(rt0->rt6i_flags & RTF_EXPIRES) && rt0->from)
rt0->dst.expires = rt0->from->dst.expires;
dst_set_expires(&rt0->dst, timeout);
rt0->rt6i_flags |= RTF_EXPIRES;
}
With the fib6_info I can keep that logic with:
static inline void rt6_update_expires(struct rt6_info *rt0, int timeout)
{
if (!(rt0->rt6i_flags & RTF_EXPIRES) && rt0->from)
rt0->dst.expires = rt0->from->expires;
dst_set_expires(&rt0->dst, timeout);
rt0->rt6i_flags |= RTF_EXPIRES;
}

I think the RTF_EXPIRES check should also be skipped. Otherwise,
the already-exist rt6_cache will not get a new expires after
another pmtu exception.
A nit. It seems rt6_update_expires() is only used by
rt6_do_update_pmtu(). It could be more readable
to move these codes to rt6_do_update_pmtu() such that
we know it is a special handling for pmtu case.
(i.e. remove rt6_update_expires()).
