* [PATCH 6/8] ipv4: udp: Optimise multicast reception
From: Eric Dumazet @ 2009-11-08 20:18 UTC (permalink / raw)

UDP multicast rx path is a bit complex and can hold a spinlock
for a long time.
Using a small (32 or 64 entries) stack of socket pointers can help
to perform expensive operations (skb_clone(), udp_queue_rcv_skb())
outside of the lock, in most cases.
It's also a base for a future RCU conversion of multicast recption.

We first locate the (local port) hash chain head
If few sockets are in this chain, we proceed with previous lookup algo.
If too many sockets are listed, we take a look at the secondary
(port, address) hash chain.
We choose the shortest chain and proceed with a RCU lookup on the elected chain.
But, if we chose (port, address) chain, and fail to find a socket on given address,
we must try another lookup on (port, in6addr_any) chain to find sockets not bound
to a particular IP.
-> No extra cost for typical setups, where the first lookup will probabbly
be performed.
RCU lookups everywhere, we dont acquire spinlock.

* [PATCH 3/8] udp: secondary hash on (local port, local address)
From: Eric Dumazet @ 2009-11-08 20:17 UTC (permalink / raw)
To: David S. Miller
Cc: Linux Netdev List, Lucian Adrian Grijincu, Octavian Purdila
Extends udp_table to contain a secondary hash table.
socket anchor for this second hash is free, because UDP
doesnt use skc_bind_node : We define an union to hold
both skc_bind_node & a new hlist_nulls_node udp_portaddr_node
udp_lib_get_port() inserts sockets into second hash chain
(additional cost of one atomic op)
udp_lib_unhash() deletes socket from second hash chain
(additional cost of one atomic op)
Note : No spinlock lockdep annotation is needed, because
lock for the secondary hash chain is always get after
lock for primary hash chain.

From: Eric Dumazet @ 2009-11-08 20:17 UTC (permalink / raw)
To: David S. Miller
Cc: Linux Netdev List, Lucian Adrian Grijincu, Octavian Purdila
Union sk_hash with two u16 hashes for udp (no extra memory taken)
One 16 bits hash on (local port) value (the previous udp 'hash')
One 16 bits hash on (local address, local port) values, initialized
but not yet used. This second hash is using jenkin hash for better
distribution.
Because the 'port' is xored later, a partial hash is performed
on local address + net_hash_mix(net)

* [PATCH 0/8 net-next-2.6] udp: optimisations
From: Eric Dumazet @ 2009-11-08 20:16 UTC (permalink / raw)
To: David S. Miller
Cc: Linux Netdev List, Lucian Adrian Grijincu, Octavian Purdila
This patch series address UDP scalability problems, we failed to solve in 2007
(commit 6aaf47fa48d3c44 INET : IPV4 UDP lookups converted to a 2 pass algo)
we had to revert a bit later.
One of the problem of UDP is its use of a single hash table, with
a key based on local port value only. When many IP addresses are used,
it is possible to have a chain with very large number N of sockets,
lookup time being N/2 in average.
Size of hash table has no effect on this, since all sockets are
chained in one particular slot.
It seems Lucian Adrian Grijincu & Octavian Purdila from IXIACOM have
real workloads hitting hard this problem and posted a preliminary
patch/RFC, using a second hash, but based on (local address).
I took part of Lucian ideas and my previous patches, and cooked
a clean upgrade path.
With following patches, we might handle 1.000.000+ udp sockets
in linux without major slowdown, and no penalty for common cases.
Thanks
[PATCH 1/8] udp: add a counter into udp_hslot
Adds a counter in udp_hslot to keep an accurate count
of sockets present in chain.
This will permit to upcoming UDP lookup algo to chose
the shortest chain when secondary hash is added.
[PATCH 2/8] udp: split sk_hash into two u16 hashes
nion sk_hash with two u16 hashes for udp (no extra memory taken)
One 16 bits hash on (local port) value (the previous udp 'hash')
One 16 bits hash on (local address, local port) values, initialized
but not yet used. This second hash is using jenkin hash for better
distribution.
Because the 'port' is xored later, a partial hash is performed
on local address + net_hash_mix(net)
[PATCH 3/8] udp: secondary hash on (local port, local address)
Extends udp_table to contain a secondary hash table.
socket anchor for this second hash is free, because UDP
doesnt use skc_bind_node : We define an union to hold
both skc_bind_node & a new hlist_nulls_node udp_portaddr_node
udp_lib_get_port() inserts sockets into second hash chain
(additional cost of one atomic op)
udp_lib_unhash() deletes socket from second hash chain
(additional cost of one atomic op)
Note : No special lockdep annotation is needed, because
lock for the secondary hash chain is always get after
lock for primary hash chain.
[PATCH 4/8] ipv4: udp: optimize unicast RX path
We first locate the (local port) hash chain head
If few sockets are in this chain, we proceed with previous lookup algo.
If too many sockets are listed, we take a look at the secondary
(port, address) hash chain.
We choose the shortest chain and proceed with a RCU lookup on the elected chain.
But, if we chose (port, address) chain, and fail to find a socket on given address,
we must try another lookup on (port, INADDR_ANY) chain to find sockets not bound
to a particular IP.
-> No extra cost for typical setups, where the first lookup will probabbly
be performed.
RCU lookups everywhere, we dont acquire spinlock.
[PATCH 5/8] ipv6: udp: optimize unicast RX path
Same algo than patch 4, but for ipv6
[PATCH 6/8] ipv4: udp: Optimise multicast reception
UDP multicast rx path is a bit complex and can hold a spinlock
for a long time.
Using a small (32 or 64 entries) stack of socket pointers can help
to perform expensive operations (skb_clone(), udp_queue_rcv_skb())
outside of the lock, in most cases.
It's also a base for a future RCU conversion of multicast recption.
[PATCH 7/8] ipv6: udp: Optimise multicast reception
Same optimisation, but for ipv6
[PATCH 8/8] udp: multicast RX should increment SNMP/sk_drops counter in allocation failures
When skb_clone() fails, we should increment sk_drops and SNMP counters.
This fix is not urgent and better done after previous patches.
-------------------------------------------------------------------------------------
Furthers patches could be :
udp: bind() optimisations
udp: multicast uses of secondary hash
udp: multicast path uses RCU

Makes sense to me as well. Which does provide some time to come up with
a primitive designed to answer the question "Am I currently executing in
the context of a workqueue item?". ;-)

There are a number of places that have the pattern of skipping
whitespace, calling simpler_strtoul(), and then skipping whitespace
afterwards. And thinkpad_acpi.c and fs/ext4/super.c both have an
indentical function, parse_strotul(), which basically does this plus
doing actual error checking (a number of callers of simple_strtoul
aren't checking to see if the user passed in a valid number or not,
boo.)
I would suggest that we should lift parse_strtoul() into lib/, both to
save a bit of code, as well as encouraging people to do proper input
validation, while we are doing this tree-wide cleanup.

Differently of "static void strip(char *str)"@scripts/kconfig/conf.c ,
this function
does not moves the characters to the beginning of the string, so that if that
string is going to be reused it should refer to the newly returned string start.
I've changed it to remove the const and return a "char *".
Do you think __must_check is not needed as well?

Looks fine but for one thing: it's actually shorter inline than moved
into /lib so at the very least it should be a header inline not a
function call.
Second minor comment. Although it never made it into the final ANSI C,
the proposed name (and the one used in a lot of other non Linux code for
this) is stpblk().

Before we embark on something as massive as this, could we take a step
back. I agree that if I were coming up with the strstip() interface
today I probably wouldn't have given it two overloaded uses.
However, I think the function, in spite of this minor issue, is very
usable. I still don't understand why people thought adding a
__must_check, which is what damaged one of the overloaded uses, is a
good idea.
Assuming there's a good answer to the above:

> + *
> + * Returns a pointer to the first non-whitespace character in @s.

> +const char *skip_spaces(const char *str)
I don't think const return is a good idea because most functions will be
manipulating the string and using pointers that won't be const, so this
will generate a ton of 'initialization discards qualifiers from pointer
target type' ... so that leads to the question of whether this patch
series was actually compiled ...

* [PATCH] net: netlink_getname, packet_getname -- use DECLARE_SOCKADDR guard
From: Cyrill Gorcunov @ 2009-11-08 15:51 UTC (permalink / raw)
To: LNML; +Cc: David Miller, Eric Dumazet
Use guard DECLARE_SOCKADDR in a few more places which allow
us to catch if the structure copied back is too big.

* [PATCH 2/2 net-next-2.6] au1000-eth: convert to platform_driver model
From: Florian Fainelli @ 2009-11-08 14:42 UTC (permalink / raw)
To: linux-mips, Ralf Baechle; +Cc: netdev, David Miller
This patch converts the au1000-eth driver to become a full
platform-driver as it ought to be. We now pass PHY-speficic
configurations through platform_data but for compatibility
the driver still assumes the default settings (search for PHY1 on
MAC0) when no platform_data is passed. Tested on my MTX-1 board.

* [PATCH v4] alchemy: add au1000-eth platform device
From: Florian Fainelli @ 2009-11-08 14:42 UTC (permalink / raw)
To: linux-mips, David Miller; +Cc: Ralf Baechle, netdev
This patch makes the board code register the au1000-eth
platform device. The au1000-eth platform data can be
overriden with the au1xxx_override_eth_cfg function
like it has to be done for the Bosporus board which uses
a different MAC/PHY setup.
Changes from v3:
- declare a static au1000_eth_platform_data structure for bosporus and
initialize it
- remove parenthis and bit shifting on SYS_PF_NI2
Changes from v2:
- declared the au1000-eth second driver instance platform_data
- made the override function generic and pass it the port number too
Changes from v1:
- remove per-board platform.c file
- add an override function to pass custom eth0 platform_data PHY settings

* query: net-next section mismatch(es)
From: William Allen Simpson @ 2009-11-08 14:13 UTC (permalink / raw)
To: Linux Kernel Network Developers
Yesterday morning (and for a month), I was getting the usual:
WARNING: modpost: Found 1 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'
This morning, it changed:
WARNING: modpost: Found 4 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'
I remember compiling it once with that option, and not finding anything
wrong in my code, but I'm wondering how it took a great leap?

Very nice patches again!
Looking at what you did, I had two ideas how to move on from there,
which may be part of your plans already:
1. Make it possible to build sysctl_binary.c as a loadable module
so you can get a smaller kernel without losing the option to use
binary sysctl altogether. This of course requires a small portion
to remain in the kernel, to provide the actual syscall entry point
and load the module on demand.
2. On top of that, put the same code into glibc so that you don't
even have to load the module when you're running a new glibc version.
Since the binary sysctl ABI is stable (as in stiff and dead), there
should be no need to synchronize any extensions to it betwen kernel
and libc.

* [PATCH 09/23] sysctl net: Remove unused binary sysctl code
From: Eric W. Biederman @ 2009-11-08 12:21 UTC (permalink / raw)
To: linux-kernel; +Cc: Eric W. Biederman, David Miller, Hideaki YOSHIFUJI, netdev
In-Reply-To: <m14op5jjo4.fsf@fess.ebiederm.org>
From: Eric W. Biederman <ebiederm@xmission.com>
Now that sys_sysctl is a compatiblity wrapper around /proc/sys
all sysctl strategy routines, and all ctl_name and strategy
entries in the sysctl tables are unused, and can be
revmoed.
In addition neigh_sysctl_register has been modified to no longer
take a strategy argument and it's callers have been modified not
to pass one.

* [PATCH 00/23] Removal of binary sysctl support
From: Eric W. Biederman @ 2009-11-08 12:20 UTC (permalink / raw)
To: linux-kernel; +Cc: netdev, David Miller, Stephen Rothwell
This patchset reimplements sys_sysctl as a compatibility wrapper
around /proc/sys. After which it removes all of the code to all over
the kernel that is used today to implement the binary sysctls.
I am posting this patchset to give everyone a heads up what is in
flight.
I intend to carry all of these patches in my sysctl tree.
If you add new sysctls to other trees please don't set the .ctl_name
or .strategy fields in struct ctl_table, as setting those fields
is unnecessary now and are removed by this patchset.
Last I looked at linux-next is only one new sysctl that is not in
Linus's tree under net/ipv6. David I will send you a patch in a
bit to remove the unnecessary .ctl_name = CTL_UNNUMBERED line so
that linux-next continues to compile when my tree makes it there.

Thanks for the review! I'll add more polishing and repost.

Hmm ... yes. tx poll stop is called on each packet (as long as we do not
fill up 1/2 backend queue), the first call will stop polling
the rest checks state and does nothing.
This is because we normally do not care when the message has left the
queue in backend device: we tell backend to send it and forget. We only
start polling when backend tx queue fills up.
Makes sense?

In fact, I think this is not a bug. This happens to work correctly
(even with malicious guests) because vhost_get_vq_desc is hard-coded to
check VHOST_NET_MAX_SG, so in fact no overflow is possible. I agree
that it's mich nicer to pass iovec size to vhost_get_vq_desc.

OKay, I'll look into this. It kind of annoys me that we would do
get_user for the same value twice: once in vhost_enable_notify and once
in vhost_get_vq_desc. OTOH, all the loop does is call vhost_get_vq_desc
again.

I don't think it can, if we enabled notification and then see more
descriptors in queue, we want to disable notification again. But it can
be

if (unlikely(vhost_enable_notify(vq))) {
/* Try again, they have slipped one in. */
vhost_disable_notify(vq);
continue;

You mean zalloc?

Hmm, varargs sounds a bit complex. But I agree readability for
vhost_net_enable_vq and friends would benefit from passing a vq around
rather than an index. I'll try it out and do it if it's a win.

Not sure how do you mean. Userspace sets them, why

Not by much though, right?

The problem is with VHOST_SET_VRING_BASE as well. I want it to be
separate because I want to make it possible to relocate e.g. used ring
to another address while ring is running. This would be a good debugging
tool (you look at kernel's used ring, check descriptor, then update
guest's used ring) and also possibly an extra way to do migration. And
it's nicer to have vring size separate as well, because it is
initialized by host and never changed, right?
We could merge DESC, AVAIL, USED, and it will reduce the amount of code
in userspace. With both base, size and fds separate, it seemed a bit
more symmetrical to have desc/avail/used separate as well.
What's your opinion?

Yes. It's not too late to split it out though: should I do it yet?

I tried to cut and paste as many comments as possible, this
made it easy to audit the code by comparing it with lguest,
and made them much more witty. But yes, this is definitely going
overboard as we do not have vq->call at all :)

Sounds good. Since I'm renaming vhost_notify to vhost_enable_notify,
this one can just become vhost_notify.
