It is a good idea.

Yet, what is the intention of the dynamic to alloc/free stats_block?
what will be affected by allocating the statistics block.

My only interest in this is to help figure out how to make IPv6 ndisc

Fair enough.  And in at least some of those situations the dst metadata
will be needed on every packet.  I think the extra allocation per packet
for the metadata dst is unfortunate but I won't say it is wrong.

We can't use the metadata dst for IPv6 neighbour discovery.  Neighbour
discovery processing comes after ip6_route_input.  That is what makes
such a network device operation interesting today.

We don't need the information in the metadata dst because the
information that was in the metadata dst is still in the packet we just
need to reparse the packet.

Given that the input network device is per tunnel type, the network
device method will already know the format of the tunnel packet and so
should not have any trouble parsing it.

As an assist we can preserve 90% of the information in ip_tunnel_key by
repurposing inner_transport_header, inner_network_header and
inner_mac_header (which are only valid on output packets today) as
outer_transport_header, outer_network_header and outer_mac_header for
input packets.

That makes tun_id the only field of struct ip_tunnel_key that we have to
work to find.



Creating outer_transport_header, outer_network_header and
outer_mac_header should open up a lot of optmization opportunities
for input tunnel processing.  I expect with just a little bit of care
we should be able to replace the input metadata dst with a handful
of fields stored in skb->cb.  Which in turn means no memory allocations
are necessary, and that the work can be done unconditionally.

[PATCH net-next 1/3] l2tp: auto load type modules

2015-09-23 Thread Stephen Hemminger
It should not be necessary to do explicit module loading when
configuring L2TP. Modules should be loaded as needed instead
(as is done already with netlink and other tunnel types).

This patch adds a new module alias type and code to load
the sub module on demand.

Hmmm... yeah, you can say that, but it still was a failure to

So, while that also has been a common failure mode that we've been
seeing with barrier usages, what you're suggesting isn't the right
balance either.  It's error-prone in a different way as amply
exemplified in this very thread.  It ended up making what should have

Both misusages can be solved by understanding and sticking to

Well we'll have to agree to disagree on that one.  I have seen too

I think this is where we're not agreeing.  My point is that better
understanding and lower likelihood of bug doesn't equate specializing
each usage site.  That's a lot more likely to lead to unnecessary
cognition overhead and naturally errors.  There's no reason to require
such error-prone and specific understanding of each usage site when we

This isn't an isolated one-off barrier hack.  This is a
well-established pattern and sure there are cases we wanna deconstruct
that and make exceptions but that needs to be justifiable.  The
overhead gotta buy us something.  Here it just doesn't.

Thanks.

What I am concerned about is the next guy who comes along and
does a rewrite like the one that introduced the netlink_bind
bug.  That person needs to fully understand what each primitive
is protecting against.

Using primitives where they're not needed can lead to misunderstandings
which may end up causing bugs.

Honestly I don't care whether you have a barrier there or not as
I only use x86.  But you very much should add a comment at least
saying that the barrier isn't needed for the cases where I left it
out so that future developers don't get confused.

This part is fine.

Hmm... It looks like I'm failing at communicating.  Lemme try again.
There are two situations where we do this.

1. When there are different locking contexts.  In this case, the write
   path is.  It's already protected by the spinlock so the barrier
   isn't necessary.

2. When the path is hot enough for the cost of smp_rmb() to matter and
   the specifics of individual deref allows for micro optimization and
   justifies the added overhead in terms of increased fragility,
   complexity and need for documentation.

In both cases, we want to make reasonable trade-offs like any other
choices we make.  We don't go off and run to one extreme or the other
just because barriers are involved.  One good measure to use is
whether the extra documentation necessary is justifiable.  In this
case, on each unprotected derefs, we want to explain why the
unprotected deref is okay and justified.

store_release/load_acquire vs. wmb/rmb is a separate issue.  I no
longer have objections against using wmb/rmb pairs here although I do
wanna note that eventually I think release/acquire are likely to be
more prevalent but that's a separate discussion.

Thanks.

Well if someone provided helpers which

1) uses smp_wmb and smp_rmb instead of full barriers;
2) provides raw variants for the cases that barriers aren't needed

then I'm more than happy to use them.

Having reviewed the situation again I'm even more convincend
now that smp_load_acquire/smp_store_release aren't the appropriate
primitives for us.  They are meant for situations that are similar
to spin lock/unlock where you need to prevent all reads/writes from
floating above or below the load/store, respectively.

For our situation we only need write or read ordering, so they are
literally the wrong tool for the job and will only cause confusion
in future when someone tries to do a major rewrite of the code and
they will be scratching their head as to why we needed locking-like
semantics here.

It does affect the intention. Although, the problem exists then makes the
system panic within some case.

Do you have any idea about it?

HNS can be configured to work on different mode for different scenario.
This patch make use only some of the mode to make it as standard
ethernet NIC. The other mode will be added soon.

The whole function has 4 kernel sub-modules:

hnae: the HNS acceleration engine framework. It provides a abstract
interface between the engine and the upper layers which make use of the
engine by ring buffer.

hns_enet_drv: a standard ethernet driver that base on the ring buffer.

hns_dsaf: one of the implementation of HNS acceleration engine, which is
applied on Hililicon hip05, Hi1610 and other later-on SoCs

hns_mdio: the mdio control to the PHY, used by acceleration engine

[PATCH nf-next 23/84] ipvs: Cache ipvs in ip_vs_in_icmp and ip_vs_in_icmp_v6

2015-09-23 Thread Simon Horman
From: "Eric W. Biederman" 

Storte the value of net_ipvs in a variable named ipvs so that when
there are more users struct netns_ipvs in ip_vs_in_cmp and
ip_vs_in_icmp_v6 they won't need to compute the value again.

[PATCH nf-next 05/84] ipvs: Store ipvs not net in struct ip_vs_conn_param

2015-09-23 Thread Simon Horman
From: "Eric W. Biederman" 

In practice struct netns_ipvs is as meaningful as struct net and more
useful as it holds the ipvs specific data.  So store a pointer to
struct netns_ipvs.

Update the accesses of param->net to access param->ipvs->net instead.

When lookup up struct ip_vs_conn in a hash table replace comparisons
of cp->net with comparisons of cp->ipvs which is possible
now that ipvs is present in ip_vs_conn_param.

[PATCH nf-next 02/84] ipvs: Don't use current in proc_do_defense_mode

2015-09-23 Thread Simon Horman
From: "Eric W. Biederman" 

Instead store ipvs in extra2 so that proc_do_defense_mode can easily
find the ipvs that it's value is associated with.

[PATCH nf-next 07/84] ipvs: Store ipvs not net in struct ip_vs_service

2015-09-23 Thread Simon Horman
From: "Eric W. Biederman" 

In practice struct netns_ipvs is as meaningful as struct net and more
useful as it holds the ipvs specific data.  So store a pointer to
struct netns_ipvs.

Update the accesses of param->net to access param->ipvs->net instead.

In functions where we are searching for an svc and filtering by net
filter by ipvs instead.

2015-09-23 Thread Simon Horman
From: "Eric W. Biederman" 

Use the address of ipvs not the address of net when computing the
hash value.  This removes an unncessary dependency on struct net.

[PATCH nf-next 61/84] ipvs: Pass ipvs into .conn_in_get and ip_vs_conn_in_get_proto

2015-09-23 Thread Simon Horman
From: "Eric W. Biederman" 

Stop relying on "net_ipvs(skb_net(skb))" to derive the ipvs as
skb_net is a hack.

[PATCH nf-next 04/84] ipvs: Store ipvs not net in struct ip_vs_conn

2015-09-23 Thread Simon Horman
From: "Eric W. Biederman" 

In practice struct netns_ipvs is as meaningful as struct net and more
useful as it holds the ipvs specific data.  So store a pointer to
struct netns_ipvs.

Update the accesses of conn->net to access conn->ipvs->net instead.

[PATCH nf-next 01/84] ipvs: Hoist computation of ipvs earlier in sctp_conn_schedule

2015-09-23 Thread Simon Horman
From: "Eric W. Biederman" 

The addition of sysctl_sloppy_sctp in sctp_conn_schedule resulted
in a use of ipvs before it was computed.  Hoist the computation of
ipvs earlier to avoid this problem.

[PATCH nf-next 60/84] ipvs: Pass ipvs into ip_vs_conn_fill_param_proto

2015-09-23 Thread Simon Horman
From: "Eric W. Biederman"

so it is easier to remove.

[PATCH nf-next 67/84] ipvs: Better derivation of ipvs in ip_vs_tunnel_xmit

2015-09-23 Thread Simon Horman
From: "Eric W. Biederman" 

Don't use "net_ipvs(skb_net(skb))" as skb_net is a bad hack.  Instead
use cp->ipvs and ipvs->net for the net.

[PATCH nf-next 77/84] ipvs: Pass ipvs into ip_vs_in_icmp and ip_vs_in_icmp_v6

2015-09-23 Thread Simon Horman
From: "Eric W. Biederman" 

With ipvs passed into ip_vs_in_icmp and ip_vs_in_icmp_v6
they no longer need to call the hack that is skb_net.

Additionally ipvs_in_icmp no longer needs to call dev_net(skb->dev)
and can use the ipvs->net instead.

[PATCH nf-next 63/84] ipvs: Pass ipvs not net to ip_vs_conn_hashkey

2015-09-23 Thread Simon Horman
From: "Eric W. Biederman" 

Use the address of struct netns_ipvs in the hash not the address of
struct net.  Both addresses are equally valid candidates and by using
the address of struct netns_ipvs there becomes no need deal with
struct net in this part of the code.

[PATCH nf-next 72/84] ipvs: Wrap sysctl_cache_bypass and remove ifdefs in ip_vs_leave

2015-09-23 Thread Simon Horman
From: "Eric W. Biederman" 

With sysctl_cache_bypass now a compile time constant the compiler can
figue out that it can elimiate all of the code that depends on
sysctl_cache_bypass being true.

Also remove the duplicate computation of net previously necessitated
by #ifdef CONFIG_SYSCTL
