FWIW, if you have a digital camera I'm happy with a picture too, no need
to hand-transcribe everything.

Maybe that device simply never stops/wakes the queues in the same way.
Or the difference is that b43legacy has only a single queue available to
it (right now) and no QoS.

Hmm. That decodes (script/decodecode) to
All code
========
0: ec in (%dx),%al
1: 10 4c 89 65 adc %cl,0x65(%rcx,%rcx,4)
5: f8 clc
6: 48 89 5d f0 mov %rbx,-0x10(%rbp)
a: 49 89 fc mov %rdi,%r12
d:* 3c 0f cmp $0xf,%al <-- trapping instruction
f: ba af 80 00 00 mov $0x80af,%edx
...
which is odd because that function doesn't seem to have a comparison to
0xf (15) in it as far as I can tell.
I'm pretty stumped. Does this reproduce well? Maybe you can print out
the queue number in the propagate wake function?

* [PATCH resend] rds_rdma: don't assume infiniband device is PCI

RDS code assumes that the struct ib_device dma_device member, which is a
pointer, points to a struct device embedded in a struct pci_dev.
This is not the case for ehca, for example, which is a OF driver, and
makes dma_device point to a struct device embedded in a struct
platform_device.
This will make the system crash when rds_rdma is loaded in a system
with ehca, since it will try to access the bus member of a non-existent
struct pci_dev.
The only reason rds_rdma uses the struct pci_dev is to get the NUMA node
the device is attached to. Using dev_to_node for that is much better,
since it won't assume which bus the infiniband is attached to.

Hm... Odd, I thought it uses UDP because there I saw it using udp_disconnect, udp_ioctl, and friends...

Sure!
The code is pretty simple:
#include <linux/l2tp.h>
#include <sys/types.h>
#include <sys/socket.h>
void main(void)
{
struct sockaddr addr = { .sa_family = AF_UNSPEC };
connect(socket(AF_INET, SOCK_DGRAM, IPPROTO_L2TP), &addr, sizeof(addr));
}
And the BUG it produces:

L2TPv3 also supports IP encapsulation, which is L2TP directly in IP, no
UDP. That's what the l2tp_ip[6] code implements.
Can you post an oops with steps for how to reproduce it?

Concerning (1):
I think, there are places where you may have troube because you don't
hold the lock.
E.g., in tcp_make_synack (called by tcp_v4_send_synack from your
tcp_v4_syn_conn_limit) there is:
if (sk->sk_userlocks & SOCK_RCVBUF_LOCK &&
(req->window_clamp > tcp_full_space(sk) ||
req->window_clamp == 0))
req->window_clamp = tcp_full_space(sk);
Thus, tcp_full_space(sk) may have different values between the check and
setting req->window_clamp.
Concerning (2):
Imagine, a SYN coming in, when the reqsk-queue is not yet full. A
request-sock will be added to the reqsk-queue. Then, a retransmission of
this SYN comes in and the queue got full by the time. This time
tcp_v4_syn_conn_limit will do syn-cookies and thus generate a different
seq-number for the SYN/ACK.
But I don't see how you could fix these issues in your proposed framework.
Cheers,
Christoph

* Wrong usage of hash in L2TP leading to NULL ptr derefs
From: Sasha Levin @ 2012-05-28 16:12 UTC (permalink / raw)
To: Eric Dumazet, David Miller, jchapman
Cc: netdev@vger.kernel.org, linux-kernel@vger.kernel.org
Hi all,
Looking at net/l2tp/l2tp_ip{6}.c, l2tp uses UDP for communications, but
uses inet_hash and inet_unhash for hashing - which appears to be wrong
(and causes NULL ptr derefs during runtime).
Since I'm not too familiar with the protocol, I'm not sure if the right
fix would be to switch it to use the UDP hashing code, or to actually
initialize everything inet_hash() expects so the current hashing would
work properly.
Help appreciated!
Thanks,
Sasha

* some questions on virtual machine bridging.
From: Luigi Rizzo @ 2012-05-28 16:13 UTC (permalink / raw)
To: netdev
I am doing some experiments with implementing a software bridge
between virtual machines, using netmap as the communication API.
I have a first prototype up and running and it is quite fast (10 Mpps
with 60-byte frames, 4 Mpps with 1500 byte frames, compared to the
~500-800Kpps @60 bytes that you get with the tap interface used by
openvswitch or the native linux bridging).
I was wondering if anyone has comments/suggestions on the following:
* what kind of API is used by the various virtualization solution to
do virtual machine switching ?
- On linux, kvm seems to rely on "tap" interfaces and native linux
bridging, which i believe is more or less the same solution used
by FreeBSD.
- Slightly less efficient is perhaps the use of a socket
and multicast packets, or bpf.
- and of course, using PCI passthrough you get more or less hw speed
(constrained by the OS), but need support from an external switch
or the NIC itself to do forwarding between different ports.
anything else ?
* any high-performance virtual switching solution around ?
As mentioned, i have measured native linux bridging and in-kernel ovs
and the numbers are above (not surprising; the tap involves a syscall
on each packet if i am not mistaken, and internally you need a
data copy)
* how many ports should i support ?
* the hash function normally used for bridging (both in Linux and
in FreeBSD -- see the latter below) is one of the Jenkins functions.
It seems to take about 20ns to compute on my machine, which is a
non-negligible amount of time (haven't tried to optimize it).
Any reference on why this is so popular ?
cheers

The BUG_ON() in pack_sg_list() would get triggered only one time after we've
corrupted some memory by sg_set_buf() into an invalid sg buffer.
I'm still working on figuring out why I manage to trigger that bug...

Looks like this isn't in the 3.5 pull request -
just lost in the shuffle?
disable_cb is advisory so can't be relied upon.

* [RFC PATCH 1/2] tcp: extract syncookie part of tcp_v4_conn_request()

Place SYN cookie handling, from tcp_v4_conn_request() into seperate
function, named tcp_v4_syn_conn_limit(). The semantics should be
almost the same.
Besides code cleanup, this patch is preparing for handling SYN cookie
in an ealier step, to avoid a spinlock and achive parallel processing.

* [RFC PATCH 0/2] Faster/parallel SYN handling to mitigate SYN floods
From: Jesper Dangaard Brouer @ 2012-05-28 11:52 UTC (permalink / raw)

The following series is a RFC (Request For Comments) for implementing
a faster and parallel handling of TCP SYN connections, to mitigate SYN
flood attacks. This is against DaveM's net (f0d1b3c2bc), as net-next
is closed, as DaveM has mentioned numerous times ;-)
Only IPv4 TCP is handled here. The IPv6 TCP code also need to be
updated, but I'll deal with that part after we have agreed on a
solution for IPv4 TCP.
Patch 1/2: Is a cleanup, where I split out the SYN cookie handling
from tcp_v4_conn_request() into tcp_v4_syn_conn_limit().
Patch 2/2: Move tcp_v4_syn_conn_limit() outside bh_lock_sock() in
tcp_v4_rcv(). I would like some input on, (1) if this safe without
the lock, (2) if we need to do some sock lookup, before calling
tcp_v4_syn_conn_limit() (Christoph Paasch
<christoph.paasch@uclouvain.be> mentioned something about SYN
retransmissions)

In-Reply-To: <20120528115102.12068.79994.stgit@localhost.localdomain>
TCP SYN handling is on the slow path via tcp_v4_rcv(), and is
performed while holding spinlock bh_lock_sock().
Real-life and testlab experiments show, that the kernel choks
when reaching 130Kpps SYN floods (powerful Nehalem 16 cores).
Measuring with perf reveals, that its caused by
bh_lock_sock_nested() call in tcp_v4_rcv().
With this patch, the machine can handle 750Kpps (max of the SYN
flood generator) with cycles to spare, CPU load on the big machine
dropped to 1%, from 100%.
Notice we only handle syn cookie early on, normal SYN packets
are still processed under the bh_lock_sock().

You might want to consider converting to call_usermodehelper()
I know that it greatly simplified our code both in Kernel and
in user-mode. And it made nfs-utils maintainer much happier
as well.

* [PATCH 1/2] tc(8): Negative indent and missing "-" after an escape
From: Andreas Henriksson @ 2012-05-28 11:46 UTC (permalink / raw)

<groff: tc.8>:51: warning: total indent cannot be negative
<groff: tc.8>:57: warning: escape character ignored before `i'
*********************
Space at end of line removed
General considerations
a) Manuals should usually only be left justified. Use ".ad l"
as the first regular command.
b) Each sentence should begin on a new line. The conventions
about the amount of space between sentences are different. This
also makes a check on the number of space characters between
words easier.
c) Separate numbers from units with a (no-break) space. A
no-break space can be code 0xA0, "\ " (\<space>), or "\~"
(groff).
d) Use macros "TS/TE" for tables with more than two columns.
Then use
'\" t
as the first line in the source to tell "man" to use the "tbl"
preprocessor.
e) Protect last period (full stop) in abbreviations with "\&",
if it is or might be (through new formatting of source) at the
end of line, if it is also not an end of sentence.
