* [RFC][PATCH 2/2] TCP: skip processing cached SACK blocks
From: TAKANO Ryousei @ 2007-10-04 9:44 UTC (permalink / raw)
To: netdev; +Cc: y-kodama
This patch allows to process only newly reported SACK blocks at the
sender side. An ACK packet contains up to three SACK blocks, and some
of them may be already reported and processed blocks. This patch
prevents processing of such already processed SACK blocks.

* [PATCH] mac80211: Fix TX after monitor interface is converted to managed
From: Daniel Drake @ 2007-10-04 11:33 UTC (permalink / raw)
To: linville-2XuSBdqkA4R54TAoqtyWWQ
Cc: johannes-cdvu00un1VgdHxzADdlk8Q, netdev-u79uwXL29TY76Z2rM5mHXA,
linux-wireless-u79uwXL29TY76Z2rM5mHXA
This sequence of events causes loss of connectivity:
<plug in>
<associate as normal in managed mode>
ifconfig eth7 down
iwconfig eth7 mode monitor
ifconfig eth7 up
ifconfig eth7 down
iwconfig eth7 mode managed
<associate as normal>
At this point you are associated but TX does not work. This is because
the eth7 hard_start_xmit is still ieee80211_monitor_start_xmit.
Fix this by unsetting the hard_start_xmit handler in ieee80211_if_reinit. It
will then be reinitialised to the default (ieee80211_subif_start_xmit) in
ieee80211_if_set_type.

As Oliver already wrote, different CAN transport protocols may use
different sockaddr structures. Therefore, we have made can_addr a
union. The four we have defined already, all look the same, but
other, future protocols may define a different structure.

Yes, I know inet_protosw and inet_{,un}register_protosw(). But we
can't use inet_register_protosw().
And can_proto_register() does use proto_register(). What exactly do
you want to suggest?

raw_sk is static so you can't use in another file where you include
include/net/icmp.h. There is no collision. Also, since it's inline
you won't even see it in a symbol table.
Hm, it's more than 10 years that I've tested ctags(1) and etags(1)
with several identical static names in different files and I don't
remember my results. Do these tools have a problem with multiple
defs? I think they shouldn't since C is explicitly designed for that.

When ro->ifindex != 0, the call to dev_get_by_index() shouldn't fail.
We also use lock_sock() here and in NETDEV_UNREGISTER, so there should
be no problem.

debug used to a bit mask, like it still is in core.h. You can see

I think ctags should be able to handle multiple identical static
symbols. Isn't it? I find it somewhat clumsy to write
modprobe vcan vcan_debug=1
I think it would be nice to change the module_param() macro so that
you can name the module argument and the corresponding variable
independently, like
module_param(can_debug, "debug", bool, 0444);
OK, forget that last paragraph. I've looked at the definition of
module_param() and have seen that we have module_param_named(). I
think we should use that.

I've never heard of systemtap before. I've ust looked at its overview
web page which sounds promising. I think I'll check it out when time
permits...

Sorry, I was in a hurry and didn't completed my thoughts on how to share
more code and data structures.
My first reaction was: hey, struct can_proto has almost the same
definition as struct inet_protosw, and can_proto_register() looks like
inet_register_protosw().
can_proto_register() calls proto_register, inet_register_protosw
doesn't. But protocols such as DCCP and SCTP, call both
inet_register_protosw and proto_register. Perhaps we can make
inet_register_protosw behave like can_proto_register and do the
proto_register(inet_protosw->prot) for us.
Looking at inet_init in net/ipv4/af_inet.c we see that we do the same
for udp, tcp and raw too. There we also call proto_register +
inet_register_protosw.
See the possibilites for code sharing? Having just one way of
registering protocols would reduce complexity for new protocol writers
and for people that browse the code only when trying to fix some problem
and don't want to get lost in many ways of doing the same thing.
struct can_proto could be removed and struct inet_protosw could be
renamed to reflect the fact that it is, after all, not inet specific at
all.
So this is not something to "fix" on your implementation. It looks OK.
But we could use more hands on reducing complexity on the Linux network
protocol infrastructure and you would get free fixes and improvements
when people improve the inet protocols 8)
DCCP has been collecting dividends for quite a while for working like
that 8)

* [PATCH][NETNS] Move some code into __init section when CONFIG_NET_NS=n
From: Pavel Emelyanov @ 2007-10-04 13:54 UTC (permalink / raw)
To: David Miller; +Cc: Eric W. Biederman, Linux Netdev List, devel
With the net namespaces many code leaved the __init section,
thus making the kernel occupy more memory than it did before.
Since we have a config option that prohibits the namespace
creation, the functions that initialize/finalize some netns
stuff are simply not needed and can be freed after the boot.
Currently, this is almost not noticeable, since few calls
are no longer in __init, but when the namespaces will be
merged it will be possible to free more code. I propose to
use the __net_init, __net_exit and __net_initdata "attributes"
for functions/variables that are not used if the CONFIG_NET_NS
is not set to save more space in memory.

Yet another set of double-underscored section annotations is the last thing
that is needed, methinks. :)

Thanks, it is working now. I was also glad to see the binfmt_flat
patch going in.
Do you plan to get the PHY abstraction layer patches for the Blackfin
EMAC included in the upcoming merge window?

From: Ursula Braun <braunu@de.ibm.com>
AF_IUCV socket programs may waste Linux storage, because af_iucv
allocates an skb whenever posted by the receive callback routine and
receives the message immediately.
Message receival is now postponed if data from previous callbacks has
not yet been transferred to the receiving socket program. Instead a
message handle is saved in a message queue as a reminder. Once
messages could be given to the receiving socket program, there is
an additional checking for entries in the message queue, followed
by skb allocation and message receival if applicable.

so here are the results on a net-2.6.24 kernel.
I've put the patchset here to make sure it's correct:
http://legoater.free.fr/patches/2.6.23/net-2.6.24.git-tcp_fastretrans/
and plenty of logs :
http://legoater.free.fr/patches/2.6.23/net-2.6.24.git-tcp_fastretrans.messages

The reason why BUG_ON exists is to catch bugs that happen, although

This is just paranoia. There's plenty of other BUG_ONs which we use to catch
bugs caused by drivers doing silly things. We can verify that this condition
will never occur within the mac80211 layer, so there's no need to have it.
The only thing this can catch is someone deciding to manually invoke
dev->uninit, which only the unregister code should be doing.

Bugzilla report of open bugs. Yes you could run it yourself but
many of these bugs seem to be old and need some attention or work
to get resolved.
Would this be useful to regularly run/automate?
What format?
