...But, on the other hand, default route shoudn't affect adding or
changing specific routes, so this behaviour is wrong, and IMHO this
change should be reverted or fixed.

	On replace the problem arises when same fib_info (priority, 
protocol, prefsrc, metrics, nexthops) is used in another route or routing 
table. In such cases single copy of structure is used with reference 
counter, all routes share pointer to such fib_info structure which
saves memory when we have many routes using same gateway, for example.

	No, simply the last change in 2.6.24 is wrong to assume 
duplication is evident in fib_info reference counter. And such check
is only on ip route replace/change. I'm appending brief FIB information
for your reference:

FIB - Forwarding Information Base

- Routes are organized in routing tables
- For "fib_hash" algorithm routing tables have 33 zones (for prefix
lengths 0..32), routing lookup walks them from 32 to 0 to find a
node containing all routing information
- Zones are implemented as hash tables where nodes are hashed by
key (prefix=network) because there can be lots of prefixes in a zone.
- Nodes can be stored with other methods, eg. trie, where nodes are
searched (we hope faster) by prefix and length, no zones are used
in this case
- Nodes have a list of aliases (tos+type+scope+fib_info ptr) sorted by
decreasing TOS because TOS=0 must be a last hit when looking for route.
type is unicast, local, prohibit, etc. scope is host, link, etc.
- fib_info is a structure containing protocol (kernel, boot, zebra, etc),
prefsrc, priority (metric), metrics, nexthop(s). Fallback routes have
higher value for priority, they are used if more priority routes
disappear or their nexthops are dead.
- fib_info structures are organized in 2 global hash tables, one
keyed by prefsrc and another by nexthop_count+protocol+prefsrc+priority
- fib_info is a shared structure, different aliases can point to same
fib_info, even aliases from different prefixes, from different routing
tables. By this way if fib_info contains multipath route then many
aliases share same route path scheduling context.
- Nexthop contains gateway, output device, scope and weight. Weight
is used for path scheduling where nexthops have relative priority
compared to other nexthops in multipath route.
- There can be many aliases with same tos, there can be alternative
routes (aliases) with same tos and priority (metric) but only one alias
with particular tos, type, scope and fib_info can exist to avoid duplicate
alternative routes.
- The operation to replace route includes replacing of alias. The alias
in node (table -> prefix/len) is matched by tos and fib_info priority and
they can not be changed. The parameters that are changed are type, scope
and fib_info (except priority).

* routing table
	* node (prefix/len)
		* alias (tos, type, scope)
			-> fib_info (priority, protocol, prefsrc, metrics)
				* nexthop (gateway, outdev, scope, weight)

read '*' for 'many' and '->' for 'counted reference'

Thank you very much! I've just planned to look more at this code today,
and maybe try to find how your new patch copes with this problem, so
this description should be really helpful!

But, since we agree now it's a bug and regression in 2.6.24, it seems
this should be fixed as soon as possible, and since your patch isn't
probably tested enough for stable, it looks like safe bet to revert
Joonwoo's patch, at least until this all is more verified.

* [PATCH] natsemi: Update locking documentation
From: Mark Brown @ 2008-01-27 13:58 UTC (permalink / raw)
  To: Jeff Garzik, Tim Hockin; +Cc: netdev, linux-kernel, Mark Brown

The documentation regarding synchronisation at the head of the natsemi
driver was badly bitrotted so replace it with a general statement about
the techniques used which is less likely to bitrot.

Also remove the note saying these chips are uncommon - it makes little
difference but they were used in a number of laptops and at least one mass
market PCI ethernet card.

Well, other than the obvious checkpatch.pl warnings waiting to trigger
("if" is not a function; put a space before the paren) and what I'd call
missing parens around the "flags & ...", those are *not* errors.  No
wonder you thought this would cause too many messages!!

Just make those be dev_dbg() calls instead.  The strongest message level
you can argue for there would be KERN_NOTICE, "normal but significant";
except it's not especially significant.  Filtering by netif_msg_probe()
may be a good idea too; that's normally enabled in this framework.

- Dave

p.s. Before these get submitted, *all* of them need to pass "checkpatch.pl".
  Ideally, "checkpatch.pl --strict" ...

Well, I guess I got lazy between patchsets.

I'll use dev_dbg() with netif_msg_probe().

Ok, I'll remember that now.

I'm not very familiar with posting patches (as some might have noticed)
so I have some questions.. if you don't mind. Now that you have acked
most of the patches, is it ok for me to add your 'Acked-by' to those
patches? Should I even repost all of these patches as patchset or just
ones that have been fixed? Should I post new 'physical medium' patch as
reply to this post and then repost patchset with your ack just to
mailing list?

Hm.. sure there could have been better ways of explaining that but with
my inadequate english skills that's what came out first :)

On those patches I've acked, yes.  (Unless it's a different version
from what I acked...)  You may not need to re-send them ... that's
kind of a policy choice of the subsystem maintainer (Jeff Garzik in
this case).  Most maintainers pick up acks from the mailing list, as
part of their merge process.


> Should I even repost all of these patches as patchset or just 
> ones that have been fixed?

Again, that's a subsystem-specific policy.  In most cases I'm
familiar with, the answer is to avoid needless reposting ... so
after it's acked, at most one repost-with-ack.  (And typically
not even that, when maintainers pick up the acks.)

The main reason to repost an entire patch series is to avoid
confusion that creeps in with too many tweaked versions.  On
the other hand, such reposting creates its own confusion...


> Should I post new 'physical medium' patch as 
> reply to this post and then repost patchset with your ack just to
> mailing list?

My two cents:  just post an updated version of $SUBJECT.
If Jeff wants a version with the Acks, he'll tell you
(or someone more up on netdev policies will).

At this point, assuming you update $SUBJECT patch OK,
I think this series is ready for Jeff's attention...

Add RNDIS physical medium checking into generic_rndis_bind() and also make
rndis_host to be only bind on every medium except wireless.

BTW, the way "add" works wasn't questioned now, but it seems could be,
or man ip should call it e.g. "ip route add - add new destination",
and append "ip route append" (unless I have old man).

Why can't we try goto out from here? (less reading...)

Could you comment more why returning an error seems to depend on the
order of aliases here? But, IMHO there is no reason to change the old
behavior WRT this error, so probably this err = 0 should be always if
NLM_F_REPLACE is set.

Generally this patch looks OK to me.

Thanks,

PS: I think, this FIB info you sent earlier is just fine for
Documentation/networking without any changes! (Maybe one more patch?)

* [PATCH] Implement skb_partial_csum_set
From: Rusty Russell @ 2008-01-27 22:58 UTC (permalink / raw)
  To: Linus Torvalds; +Cc: netdev

Implement skb_partial_csum_set, for setting partial csums on untrusted packets.

Use it in virtio_net (replacing buggy version there), it's also going
to be used by TAP for partial csum support.

From the link:http://marc.info/?l=linux-netdev&m=119551836927062&w=2,
he only fix the sysctl_tcp_congestion_control function.
In the latest kernel, the sysctl_string problem is present.
Can this patch be applied?

* [PATCH][INET_DIAG]: Fix inet_diag_lock_handler error path
From: Arnaldo Carvalho de Melo @ 2008-01-28  2:20 UTC (permalink / raw)
  To: David S. Miller; +Cc: Herbert Xu, spike, netdev, stable

Fixes: http://bugzilla.kernel.org/show_bug.cgi?id=9825

The inet_diag_lock_handler function uses ERR_PTR to encode errors but
its callers were testing against NULL.

This only happens when the only inet_diag modular user, DCCP, is not
built into the kernel or available as a module.

Also there was a problem with not dropping the mutex lock when a handler
was not found, also fixed in this patch.

This caused an OOPS and ss would then hang on subsequent calls, as
&inet_diag_table_mutex was being left locked.

Thanks to spike at ml.yaroslavl.ru for report it after trying 'ss -d'
on a kernel that doesn't have DCCP available.

This bug was introduced in cset
d523a328fb0271e1a763e985a21f2488fd816e7e, after 2.6.24-rc3, so just
2.6.24 seems to be affected.

I think that means the whole series is fair to merge into
the network drivers queue, assuming nobody has any issues
with the last patch (adding the actual rndis_wlan support).

Thanks for doing this ... it's nice to see folk successfully
building on top of this rndis_host code, since it started
without any "real" RNDIS devices to test against!  (Just the
Linux-USB "g_ether" peripheral code.)

...One more doubt here. Your FIB description doesn't say about this,
and a code at the end of this function, where a new alias is inserted,
doesn't seem to show this too. Are these aliases in the node sorted by
fib_priority too? I mean, isn't it possible here, that we got fa
from fib_node_alias() with right tos but greater fib_priority, but
there is a better match (with right priority) later on the list yet?
(The comment above this reads something else, but I'd be glad if you
could confirm this.)

"from fib_find_alias()" of course...

Done.

Yes, but even with the reverted commit, WOL still doesn't work. I just
tried the patch from the netdev mailing list with the 2.6.24 release
version and now WOL works for me.

OK, I see they are!

Sorry for bothering,

* 2.6.24 regression: Wake On Lan in sky2 broken on Mac mini
From: Tino Keitel @ 2008-01-28  8:42 UTC (permalink / raw)
  To: netdev

Hi folks,

with 2.6.24-rc8, Wake On LAN doesn't work anymore as it used to with
2.6.23 on my Mac mini Core Duo. I saw that this was reported in
http://bugzilla.kernel.org/show_bug.cgi?id=9721 and on netdev a patch
for the sky2 driver was sent by Stephen Hemminger. This patch fixed WOL
for me after applying it to 2.6.24-rc8.

However, it seems as the patch never made it into the kernel. Instead,
the commit that was suspected to break WOL
(84cd2dfb04d23a961c5f537baa243fa54d0987ac) was reverted
(be63a21c9573fbf88106ff0f030da5974551257b).

Now I tried the 2.6.24 release and noticed that WOL is still broken.
I'll be happy to test any patches that can make it into 2.6.24.1.

Regards,
Tino
