* [PATCH 4/7] appletalk: handle SIOCATALKDIFADDR compat ioctl
From: Arnd Bergmann @ 2009-11-06 18:09 UTC (permalink / raw)
To: linux-kernel; +Cc: David Miller, Christoph Hellwig, netdev, Arnd Bergmann
In-Reply-To: <1257530949-9695-1-git-send-email-arnd@arndb.de>
We must not have a compat ioctl handler for SIOCATALKDIFADDR
in common code, because the same number is used in other protocols
with different data structures.

* [PATCH 5/7] copy socket ioctl code to net/socket.h
From: Arnd Bergmann @ 2009-11-06 18:09 UTC (permalink / raw)
To: linux-kernel; +Cc: David Miller, Christoph Hellwig, netdev, Arnd Bergmann
In-Reply-To: <1257530949-9695-1-git-send-email-arnd@arndb.de>
This makes an identical copy of the socket compat_ioctl code
from fs/compat_ioctl.c to net/socket.c, as a preparation
for moving the functionality in a way that can be easily
reviewed.
The code is hidden inside of #if 0 and gets activated in the
patch that will make it work.

* [PATCH 6/7] compat: move sockios handling to net/socket.c
From: Arnd Bergmann @ 2009-11-06 18:09 UTC (permalink / raw)
To: linux-kernel; +Cc: David Miller, Christoph Hellwig, netdev, Arnd Bergmann
In-Reply-To: <1257530949-9695-1-git-send-email-arnd@arndb.de>
This removes the original socket compat_ioctl code
from fs/compat_ioctl.c and converts the code from the copy
in net/socket.c into a single function. We add a few cycles
of runtime to compat_sock_ioctl() with the long switch()
statement, but gain some cycles in return by simplifying
the call chain to get there.
Due to better inlining, save 1.5kb of object size in the
process, and enable further savings:

* [PATCH 1/7] compat: add struct compat_ifreq etc to compat.h
From: Arnd Bergmann @ 2009-11-06 18:09 UTC (permalink / raw)
To: linux-kernel; +Cc: David Miller, Christoph Hellwig, netdev, Arnd Bergmann
In-Reply-To: <1257530949-9695-1-git-send-email-arnd@arndb.de>
In order to move socket ioctl conversion code into multiple
places in the socket code, we need a common defintion of
the data structures it uses.
Also change the name from ifreq32 to compat_ifreq to
follow the naming convention for compat.h
Signed-off-by: Arnd Bergmann <arnd@arndb.de>

* [PATCH 2/7] net/tun: handle compat_ioctl directly
From: Arnd Bergmann @ 2009-11-06 18:09 UTC (permalink / raw)
To: linux-kernel; +Cc: David Miller, Christoph Hellwig, netdev, Arnd Bergmann
In-Reply-To: <1257530949-9695-1-git-send-email-arnd@arndb.de>
The tun driver is the only code in the kernel that operates
on a character device with struct ifreq. Change the driver
to handle the conversion itself so we can contain the
remaining ifreq handling in the socket layer.
This also fixes a bug in the handling of invalid ioctl
numbers on an unbound tun device. The driver treats this
as a TUNSETIFF in native mode, but there is no way for
the generic compat_ioctl() function to emulate this
behaviour. Possibly the driver was only doing this
accidentally anyway, but if any code relies on this
misfeature, it now also works in compat mode.

* [PATCH 7/7] net, compat_ioctl: handle more ioctls correctly
From: Arnd Bergmann @ 2009-11-06 18:09 UTC (permalink / raw)
To: linux-kernel; +Cc: David Miller, Christoph Hellwig, netdev, Arnd Bergmann
In-Reply-To: <1257530949-9695-1-git-send-email-arnd@arndb.de>
The MII ioctls and SIOCSIFNAME need to go through ifsioc conversion,
which they never did so far. Some others are not implemented in the
native path, so we can just return -EINVAL directly.
Add IFSLAVE ioctls to the EINVAL list and move it to the end to
optimize the code path for the common case.

* [PATCH 3/7] net, compat_ioctl: handle socket ioctl abuses in tty drivers
From: Arnd Bergmann @ 2009-11-06 18:09 UTC (permalink / raw)
To: linux-kernel; +Cc: David Miller, Christoph Hellwig, netdev, Arnd Bergmann
In-Reply-To: <1257530949-9695-1-git-send-email-arnd@arndb.de>
Slip and a few other drivers use the same ioctl numbers on
tty devices that are normally meant for sockets. This causes
problems with our compat_ioctl handling that tries to convert
the data structures in a different format.
Fortunately, these five drivers all use 32 bit compatible
data structures in the ioctl numbers, so we can just add
a trivial compat_ioctl conversion function to each of them.
SIOCSIFENCAP and SIOCGIFENCAP do not need to live in
fs/compat_ioctl.c after this any more, and they are not
used on any sockets.

The original vendor drivers were:
- rt2860
- rt2870
- rt3070
- rt3090
Each weighting ~100 KLOC.
The current staging drivers (rt2860 w/ RT3090 support and rt2870 w/ RT3070
support) are the result of my work on getting staging drivers under control
(+ trying some new strategies of dealing with ugly code) and weight ~75 KLOC
_together_ (they share the wireless stack code).

Could somebody please explain me (in the public or in the private) what is
the reason behind whole affair about staging drivers because all the time
I feel like I'm missing some important detail here. It would a lot more
productive than all the things that I could hear about my agenda, my work
or my intellectual abilities in the past.
[ Like I said before I got only interested into them in April this year
while doing casual staging cleanups and I'm not affiliated with any
distribution vendor. ]
Thanks.

I tried the rbtree thing and suddenly realized it was not possible at all.
This is not possible because of all wildcards we have in UDP.
1) You can for example bind a socket s1 on address X, port p, dev eth0
2) You can bind socket s2 on adress X, port p (same values as previous socket), and dev eth1
As bindtodevice can be called after bind() itself, we can get several sockets with same
rbtree key (port, address), but rbtree doesnt allow duplicates.
I'll try hash based extent.
(Ie allocate an hash extent for given primary hash slot in case number of sockets
in this hash chain exceeds 10 or some threshold)
key hash would be function_of(port, address), duplicates allowed.
allocating 4096 bytes secondary hashes would divide per 1024 or 512 time of lookups, but keeping
rcu lookup might be difficult.

* RFC 5482
From: Anirban Sinha @ 2009-11-06 18:49 UTC (permalink / raw)
To: netdev; +Cc: davem
Hi:
I am just wondering if the linux TCP/IP stack supports the RFF 5482 (TCP user
timeout option)?
http://www.faqs.org/rfcs/rfc5482.html
A grep across the source and a search in the git repository does not yield any
useful information.
Also as a side question, i am wondering if it's possible to change/control the
TCP three-way handshake timeout (reception of the last SYN_ACK) on a
per-connection basis.
Thanks,
Ani

* RFC: ethtool support for n-tuple filter programming
From: Peter P Waskiewicz Jr @ 2009-11-06 18:57 UTC (permalink / raw)
To: netdev@vger.kernel.org
All,
I'm looking to add support to ethtool that would allow programming of
full n-tuple filters into underlying devices. Currently, ixgbe has
support for these types of perfect match or mostly match (masked)
filters. I imagine other hardware exists that also has support for
this, so I'd like to make this interface usable for everyone.
Note that this is similar behavior in the iproute2 tools, but it's
different enough, in my opinion, to warrant being in ethtool. The
iproute2 tools (specifically tc) manipulate the qdiscs to add filters in
the kernel packet schedulers. This proposed solution is managing the
hardware in the underlying device, which iproute2 tools currently don't
touch. Hopefully this is obvious for those reviewing this proposal.
What I currently have as possible inputs to ethtool are:
- src/dst IP address: 32-bits each, 128-bits each for IPv6
- src/dst port: 16-bits each (TCP/UDP)
- VLAN tag: 15-bits
- L4 type: 8-bits (TCP/UDP/SCTP currently, can grow later)
- User specified field: currently 32-bits, can be anything a driver
wants to use
- Action: signed 16-bits (-1 indicates drop, any other value is the Rx
queue to steer the flow to)
Now all of these fields, except action, can also have a mask supplied to
them, but it's not mandatory.
An example ethtool command with this support could be:
# ethtool -F ethX dst-ip 0x0101a8c0 src-ip 0x0001a8c0 0x00ffffff
dst-port 0x1600 src-port 0x0000 0x0000 usr 0x8906 act 5
This will program a filter that will filter traffic coming from
192.168.1.0/24 to 192.168.1.1, port 22, from any source port, and will
place all those matches packets into Rx queue 5. It also specified a
user-defined field of 0x8906, which a driver can use at its own
discretion (or omit completely).
Then running the ethtool -f ethX command could dump all currently
programmed filters.
Any comments, thoughts, suggestions, or ideas are welcome.
Cheers,
-PJ Waskiewicz

I'm not 100% sure what you are asking, but I think you want to know
the basis for general objections from the people that hang-out on
linux-wireless and/or the rt2x00 team specifically?
I don't think anyone[1] has overwhelming objections to drivers in
staging for devices that have no other driver available. The main
objection is that drivers/staging steals users and (and often
developers) from the non-staging drivers, reducing the amount of
testing and development they get. In the effort to help some users,
drivers/staging effectively prolongs the amount of time those users
have to go without properly supported drivers. Much worse, none of
the wireless drivers in drivers/staging seem to have generated an
actual mergeable[2] wireless driver.
Further, the wireless drivers in drivers/staging are completely
isolated from the wireless infrastructure developments we've been
making over the past few years. The longer they live, the longer
wireless extensions will linger, the longer custom rfkill solutions
persist, and the longer we have multiple 802.11 stack implementations.
Finally, bug reports from drivers/staging are an unwelcome distraction
in bugzilla and the wireless mailing lists. Not only do those drivers
generate (often wierd) bugs, we get the privilege of looking like
jerks for refusing to deal with those reports even though we objected
to including the drivers in the first place.
It is little wonder to me why the linux-wireless folks oppose
drivers/staging...
Hth!
John
[1] Actually, I _know_ there are people who object to all of
drivers/staging, but few of those are actively and vigorously objecting
to it.
[2] A mergeable driver should respect and/or utilize existing wireless
infrastructure rather than duplicating it, as well as meeting general
standards of maintainability. Preferably it would have someone to
stand behind it as a maintainer as well.

The approach you are proposing assumes what type of packet filters
that L2 hardware could support.
Why not simply use existing filtering rules that overshoot the target,
such as netfilter, and ask the
device specific tool to indicate what set of these rules it can support?

Are you proposing that netfilter is modified to pass the filters down to
the hardware if it supports it? netfilter doesn't steer flows though to
queues (or flow ID's in the kernel), plus that's putting HW-specific
capabilities into netfilter. I'm not sure we want to do that.
Please correct me if I'm wrong with interpreting your suggestion.
Thanks,

* ipip: Fix handling of DF packets when pmtudisc is OFF
From: Herbert Xu @ 2009-11-06 20:37 UTC (permalink / raw)
To: David S. Miller, netdev
Hi Dave:
It appears that our tunnels are pretty much broken when pmtudisc
is turned off. It's never really showed up in the past as for
pure IP tunnels using pmtudisc is usually a better choice. But
now that we have raw Ethernet GRE tunnels that are incapable of
doing PMTU within the tunnel, people are running into these bugs
as they have to turn pmtudisc off.
I've got a number of patches that tries to address this but here
is a first to kick things off.
ipip: Fix handling of DF packets when pmtudisc is OFF
RFC 2003 requires the outer header to have DF set if DF is set
on the inner header, even when PMTU discovery is off for the
tunnel. Our implementation does exactly that.
For this to work properly the IPIP gateway also needs to engate
in PMTU when the inner DF bit is set. As otherwise the original
host would not be able to carry out its PMTU successfully since
part of the path is only visible to the gateway.
Unfortunately when the tunnel PMTU discovery setting is off, we
do not collect the necessary soft state, resulting in blackholes
when the original host tries to perform PMTU discovery.
This problem is not reproducible on the IPIP gateway itself as
the inner packet usually has skb->local_df set. This is not
correctly cleared (an unrelated bug) when the packet passes
through the tunnel, which allows fragmentation to occur. For
hosts behind the IPIP gateway it is readily visible with a simple
ping.
This patch fixes the problem by performing PMTU discovery for
all packets with the inner DF bit set, regardless of the PMTU
discovery setting on the tunnel itself.

Dave,
Three more intended for 2.6.32, two oops fixes and a revert of a patch
that traded one bug for another. One of the oops fixes reorders some
cancel_delayed_work_sync calls and the other does some bit testing to
avoid scheduling work after a device has been removed.
Please let me know if there are problems!

We can grab the smbios_name value using biosdevname in a PROGRAM= part
of the udev rule. But it doesn't actually solve the problem. We
haven't changed the network device naming scheme from "eth%d" to
something else. Therefore, by having rules which simply try to
re-order names within that scheme, when they're being enumerated in
parallel and racing, we get collisions. Take for example, this which
tries to rename the 4 onboard NICs in a particular order, in the
absence of any other rules:
PROGRAM="/sbin/biosdevname --policy=smbios_names -i %k", RESULT=="Embedded NIC 1", NAME="eth0"
PROGRAM="/sbin/biosdevname --policy=smbios_names -i %k", RESULT=="Embedded NIC 2", NAME="eth1"
PROGRAM="/sbin/biosdevname --policy=smbios_names -i %k", RESULT=="Embedded NIC 3", NAME="eth2"
PROGRAM="/sbin/biosdevname --policy=smbios_names -i %k", RESULT=="Embedded NIC 4", NAME="eth3"
I wind up with instead this in ifconfig -a:
eth0 00:1B:21:42:66:30
eth1 00:1B:21:42:66:31
eth2 00:22:19:59:8E:5A
eth2_rename 00:22:19:59:8E:56
eth3 00:22:19:59:8E:5C
eth3_rename 00:22:19:59:8E:58
When what I would have expected would have been:
eth0 00:22:19:59:8E:56
eth1 00:22:19:59:8E:58
eth2 00:22:19:59:8E:5A
eth3 00:22:19:59:8E:5C
eth4 00:1B:21:42:66:30
eth5 00:1B:21:42:66:31
I can't use eth%d as the scheme - that's the kernel's scheme. I have
to switch the scheme to something else.

Fair enough - but would you object if we changed the naming scheme
from eth%d to something else?

Sorry, no, been swamped with -stable updates. I should get to it later
today, I'll email you then if I have any problems. If not, you'll get
an email saying the patch was added to the tree.

I suppose that this would depend on what else. :-)
Since you want radical changes I recommend that you design the new
persistent naming infrastructure in a way that will allow root to choose
to use the classic naming scheme, or many users will scream a lot and at
least some distributions will do it anyway.
I also expect that providing choice at the beginning of development may
lead to more acceptance later if and when the new scheme will have
proved itself to be superior (at least in some situations).
You have tought about this for a long time and if so far you have not
found a solution which is widely considered superior then I doubt that
one will appear soon. Providing your favourite naming scheme as an
optional add on will immediately benefit those who like it and greatly
reduce opposition from those who do not.
