This is probably related to the new GEM code. But on 2.6.29-rc2 if I start up the virtual
machine manager then run a guest, the display gets screwed up.

virt-machine-manager
  click local-host (System)
  Run one of the existing VM's
 
The virtual console window then cause a dialog about allowing remote access to display;
(this never happened with earlier kernels), regression #1

Then if I allow it multiple copies of the window start cloning and general chaos ensues.

User space is Ubuntu 8.1 (x86-64)

The problem is only in the net-next tree (not mainline 2.6.29-rcX).
Bisected down to this commit is the problem:

    inet: Allowing more than 64k connections and heavily optimize bind(0) time.
    
    With simple extension to the binding mechanism, which allows to bind more
    than 64k sockets (or smaller amount, depending on sysctl parameters),
    we have to traverse the whole bind hash table to find out empty bucket.
    And while it is not a problem for example for 32k connections, bind()
    completion time grows exponentially (since after each successful binding
    we have to traverse one bucket more to find empty one) even if we start
    each time from random offset inside the hash table.
    
    So, when hash table is full, and we want to add another socket, we have
    to traverse the whole table no matter what, so effectivelly this will be
    the worst case performance and it will be constant.
    
    Attached picture shows bind() time depending on number of already bound
    sockets.

Not sure why but it breaks VNC, see attached screenshot.

Resend without screenshot that upsets vger spam filter!
The bind(0) optimization in David's net-next breaks virt machine manager when
a guest console window is started. 

virt-machine-manager
  click local-host (System)
  Run one of the existing VM's
 
The virtual console window then cause a dialog about allowing remote access to display;
(this never happened with earlier kernels), regression #1

Then if I allow it multiple copies of the window start cloning and general chaos ensues.
The problem is only in the net-next tree (not mainline 2.6.29-rcX).

Bisected down to the following commit, that breaks virt-manager

Any chance to get a bit more information about what this console does?
Like how it binds or get a strace?
Will you be able to run a debug patch which will dump lots of info into
the dmesg and slow things down a bit?

The virt-manager console is basically just a plain old boring VNC client.
It uses GTK-VNC to establish its VNC network connection, and that doesn't
do anything unusual AFAIK. We use getaddrinfo() to resolve the hostname,
and then try each of its results in turn, until we succesfully connect
to the VNC server. We don't explicitly bind() to the client port, just
let the kernel pick it for us. The code in question, is the "gvnc_open_host"
method from gvnc.c,  which starts at about line 2910

So it is not explicit bind call, but port autoselection in the
connect(). Can you check what errno is returned?
Did I understand it right, that connect fails, you try different
address, but then suddenly all those sockets become 'alive'?

Yes, I think a good strace vs. a bad strace would be really helpful
in these cases.

Thanks,

I have the strace but it comes up no different.
What is different is that in the broken case (net-next), I see
IPV6 being used:

State      Recv-Q Send-Q      Local Address:Port          Peer Address:Port   
ESTAB      23769  0        ::ffff:127.0.0.1:5900      ::ffff:127.0.0.1:55987   
ESTAB      0      0               127.0.0.1:55987            127.0.0.1:5900

and in the working case (2.6.29-rc3), IPV4 is being used
State      Recv-Q Send-Q      Local Address:Port          Peer Address:Port   
ESTAB      0      0               127.0.0.1:58894            127.0.0.1:5901    
ESTAB      0      0               127.0.0.1:5901             127.0.0.1:58894

Reviewing commit a9d8f9110d7e953c2f2b521087a4179677843c2a

I see use of a hashinfo->bsockets field that :

- lacks proper lock/synchronization
- suffers from cache line ping pongs on SMP

Also there might be a problem at line 175

if (sk->sk_reuse && sk->sk_state != TCP_LISTEN && --attempts >= 0) { 
	spin_unlock(&head->lock);
	goto again;

If we entered inet_csk_get_port() with a non null snum, we can "goto again"
while it was not expected.

It should contain rough number of sockets, there is no need to be very
precise because of this hueristic.

I used free alignment slot so that socket structure would not be
icreased.

I think it should be smallest_size != -1, since we really want to goto
to the again label when hueristic is used, which in turn changes
smallest_size.

Denying there is a bug is... well... I dont know what to say.

I wonder why we still use atomic_t all over the kernel.

Are you kidding ?

bsockets is not part of socket structure, but part of "struct inet_hashinfo",
shared by all cpus and accessed several thousand times per second on many
machines.

Please read the comment three lines after 'the free alignemnt slot'
you chose.... You just introduced one write on a cache line
that is supposed to *not* be written.

        unsigned int                    bhash_size;
        int                             bsockets;

        struct kmem_cache               *bind_bucket_cachep;

        /* All the above members are written once at bootup and
         * never written again _or_ are predominantly read-access.
         *
         * Now align to a new cache line as all the following members
         * might be often dirty.

It is not a bug. It is not supposed to be precise. At all.
I implemented a simple heuristic on when diferent bind port selection
algorithm should start: roughly when number of opened sockets equals to
some predefined value (sysctl at the moment, but it could be 64k or
anything else), so if that number is loosely maintained and does not
precisely corresponds to the number of sockets, it is not a problem.

You also saw 'again' lavel which has magic 5 number - it is another
heuristic - since lock is dropped atfer the bind bucket check, and we
selected it, it is possible that non-reuse socket will be added into the
bucket, so we will have to rerun the process again. I limited this to
the 5 attempts only, since it is better than what we have right now (I
never saw more than 2 attempts needed in the tests), when number of
bound sockets does not exceed 64k.

Yes, I mistyped.

I have no objection on moving this anywhere at the end of the structure
like after bind_bucket_cachep.

My working hypothesis is:
  1. Something about Evgeniy's patch makes IPV6 (actually IPV4 in IPV6) be
     preferred over plain IPV4.
  2. Vino server (VNC) doesn't think ::ffff::127.0.0.1 is really the localhost
  3. protocol gets screwed up after that.

It is probably reproducible with other services that support IPV6.

Nothing from above fixes the bug. It was an explaination of how things
work. Patch is based on Eric's observation about unconditional (compared
to old code) attempt to get the new socket bucket when code should just
return.

getaddrinfo() returns list of addresses and IPv6 was the first one iirc.
Previously it bailed out, but with my change it will try again without
reason for doing this. With the patch I sent based on Eric's observation
things should be fine.

Problem is your patch is wrong Evgeniy, please think about it litle bit more
and resubmit it. 

Take the time to run this $0.02 program, before and after your upcoming fix :


$ cat size.c
#include <net/inet_hashtables.h>
extern int printf(const char *, ...);
int main(int argc, char *argv[])
{

offset of bsockets being 0x18 or 0x20 is same result : bad because in
same cache line than ehash, ehash_locks, ehash_size, ehash_locks_mask,
bhash, bhash_size, unless your cpu is a Pentium.

Also, I suggest you change bsockets to something more appropriate, eg a
percpu counter.

Thank you.

No, patch should be ok. And its part which moves bsockets around was
added because of your complaints, that it is written into read-mostly
cache line. It is not a fix and has nothing with the problem at all.

It is not a fix, but enhancement, which really has nothing with the bug
in question :)
Fix is to return an error if socket binding does not use the heuristic.

Attached patch makes difference, I'm curious if it ever make any
difference in the benchmarks.

I thought on that first, but found that looping over every cpu and
summing the total number of allocated/freed sockets will have noticebly
bigger overhead than having loosely maintaned number of sockets.

For the reference. This patch has nothing with the bug we discuss here,
the proper patch (without need to move bsockets around) was sent
earlier, which forces port selection codepath to return error when new
selection heuristic is not used.

It appears you are always right, I have nothing to say then.

Stupid I am.

I vote for plain revert of your initial patch, since you are anaware
of performance problems it introduces. Then, probably nobody cares
of my complaints, so dont worry.

Eric, do not get it soo personally :) After all it is only a matter of
how we enjoy the process and have fun with the development.

Really, I appreciate your work and help, and likely this
misunderstanding happened because of a bad mix of the original bug and
this performance implication. Original bug has really nothing with what
we discuss here. And while the performance problem with bound sockets
creation may be visible, I did not observe it, while the idea
implemented with this approach shows up clearly in the graph I posted.
So I vote by both hands to further improve it by moving things around so
that there would be no unneded cache flushes during update of this
field.

OK OK, as I said, dont worry, it was not a strong feeling from me, only
a litle bit upset, thats all.

We only need to know if the *fix* is solving Stephen problem

About performance effects of careful variable placement and percpu counter
strategy you might consult as an example :

http://lkml.indiana.edu/hypermail/linux/kernel/0812.1/01624.html

Now, with these patches applied, try to see effect of your new bsockets field
on a network workload doing lot of socket bind()/unbind() calls...

With current kernels, you probably wont notice because of inode/dcache hot
cache lines, but it might change eventually...

Yes, this fixes the problem, not sure who wants the honors for sending a signed off

Impressive, but to be 100% fair it is not only because of the cache line
issues :)

David applied the patch which fixed the problem, so we can return to the
cache line issues. What do you think about the last version where
bsockets field was placed at the very end of the structure and with
cacheline_aligned_on_smp attribute?

Yes, at a minimum, move it away from first cache line.

And using atomic_t so that we dont have to discuss about accumulated
errors on SMP on this variable. We will see later if percpu counter
is wanted or not.

Thank you

And switch bsockets to atomic_t since it might be changed in parallel.
