From: Cong Ding @ 2012-12-08 23:11 UTC (permalink / raw)
To: Michael Buesch, netdev, linux-kernel; +Cc: Cong Ding
Use WARN rather than printk followed by WARN_ON(1), for conciseness.

Hi Dmitry
NULL pointer deref probably fixed on net tree (or Linus tree) by
http://git.kernel.org/?p=linux/kernel/git/davem/net.git;a=commit;h=c3c7c254b2e8cd99b0adf288c2a1bddacd7ba255
For the GRO stuff and RSS, I wonder if skbs have a property that makes
them dropped somewhere, you might try drop_monitor / drop_watch

* [PATCH net 1/3] inet_diag: fix oops for IPv4 AF_INET6 TCP SYN-RECV state
From: Neal Cardwell @ 2012-12-09 5:43 UTC (permalink / raw)
To: David Miller; +Cc: edumazet, netdev, Neal Cardwell
Fix inet_diag to be aware of the fact that AF_INET6 TCP connections
instantiated for IPv4 traffic and in the SYN-RECV state were actually
created with inet_reqsk_alloc(), instead of inet6_reqsk_alloc(). This
means that for such connections inet6_rsk(req) returns a pointer to a
random spot in memory up to roughly 64KB beyond the end of the
request_sock.
With this bug, for a server using AF_INET6 TCP sockets and serving
IPv4 traffic, an inet_diag user like `ss state SYN-RECV` would lead to
inet_diag_fill_req() causing an oops or the export to user space of 16
bytes of kernel memory as a garbage IPv6 address, depending on where
the garbage inet6_rsk(req) pointed.

* [PATCH net 2/3] inet_diag: validate byte code to prevent oops in inet_diag_bc_run()
From: Neal Cardwell @ 2012-12-09 5:43 UTC (permalink / raw)
To: David Miller; +Cc: edumazet, netdev, Neal Cardwell
In-Reply-To: <1355031803-14547-1-git-send-email-ncardwell@google.com>
Add logic to validate INET_DIAG_BC_S_COND and INET_DIAG_BC_D_COND
operations.
Previously we did not validate the inet_diag_hostcond, address family,
address length, and prefix length. So a malicious user could make the
kernel read beyond the end of the bytecode array by claiming to have a
whole inet_diag_hostcond when the bytecode was not long enough to
contain a whole inet_diag_hostcond of the given address family. Or
they could make the kernel read up to about 27 bytes beyond the end of
a connection address by passing a prefix length that exceeded the
length of addresses of the given family.

* [PATCH net 3/3] inet_diag: avoid unsafe and nonsensical prefix matches in inet_diag_bc_run()
From: Neal Cardwell @ 2012-12-09 5:43 UTC (permalink / raw)
To: David Miller; +Cc: edumazet, netdev, Neal Cardwell
In-Reply-To: <1355031803-14547-1-git-send-email-ncardwell@google.com>
Add logic to check the address family of the user-supplied conditional
and the address family of the connection entry. We now do not do
prefix matching of addresses from different address families (AF_INET
vs AF_INET6), except for the previously existing support for having an
IPv4 prefix match an IPv4-mapped IPv6 address (which this commit
maintains as-is).
This change is needed for two reasons:
(1) The addresses are different lengths, so comparing a 128-bit IPv6
prefix match condition to a 32-bit IPv4 connection address can cause
us to unwittingly walk off the end of the IPv4 address and read
garbage or oops.
(2) The IPv4 and IPv6 address spaces are semantically distinct, so a
simple bit-wise comparison of the prefixes is not meaningful, and
would lead to bogus results (except for the IPv4-mapped IPv6 case,
which this commit maintains).

-----------------
Actually in rereading the docs again, it should, but not w/o packet loss.
It has a static and a dynamic link aggregation, and though only the dynamic
link aggregation had that -- but both do and both claim to balance all
traffic.
FWIW, my cables are direct connect, so only the capabilities of the
end cards (both Intel X540-T2 cards) are at issue, I believe.
I don't know if that is a problem or not, as each of the two ports
on the cards will only see half the traffic (from the wire
that is directly connected to it).

When I did 1 link, I got about 2x faster writes, and reads that were
no faster, but I didn't do extensive testing...not sure how reliable those
figures were -- but they were sufficiently disappointing that I didn't
bother doing more testing and went immediately to trying teaming/bonding.

Not exactly, but for TCP streams, they mostly should be.
have tried a few TCP bench tests, and they got slower speeds than
my file R/W speeds through samba. So use samba for testings, as
it seems to provide fairly low overhead such that I can get
line-speed writes w/1Gb ethers and >97% line speed reads.
I'm not sure, but I think the scheduler may be coming into play
more on linux (though I would have thought it would have been Windows
slowing things down -- but I guess they got lots of grief over
their perf in WinXP and Vista... As Win7 seems to be better in that
regard. Both cards are using 9k packets, and all possible offloading.
(udp/tcp..send/receive in addition to standard chksum offloading).

I don't see that much retry traffic ... What appears maybe to be
a period drop -- like some period tic(?)...I do have tpc-low-latency,
but a 10Gb connection should low latency. Have the tcp_reordering set
to 16...which isn't a new change -- had stack tuned for optimal perf
on 1Gb....but 10gb/20gb... -- not really sure where to start...

Had no clue what to set there....
Besides, wouldn't I need to set it on the bond interface, as
it is the stream coming from the bond interface that need coalescing?
When i try it with the bond interface, I get 'not supported'
(it is on the slave interfaces, but seems like those wouldn't
"fit", as there wouldn't be contiguous i/o to either slave as
they alternate packets... (?)

FWIW, windows has 2 timers -- a 1 once/sec status timer and a 1/10sec
load tick -- but I don't see the load tick doing anything on
static aggregation.

* ixgbe: pci_get_device() call without counterpart call of pci_dev_put()
From: Elena Gurevich @ 2012-12-09 9:47 UTC (permalink / raw)
To: netdev
Hi all,
I am pioneer in linux device drivers here and using Intel 82599 NIC as
reference model,
During investigation to drivers sources I found the suspicious code:
Is code sequence (1) and (2) the possible device reference count leakage
???
Thanks a lot in advance
Lena
--------snipped from ixgbe_main.c file function ixgbe_io_error_detected()
-----------
. . .
/* Find the pci device of the offending VF */
vfdev = pci_get_device(PCI_VENDOR_ID_INTEL, device_id,
NULL);
while (vfdev) {
if (vfdev->devfn == (req_id & 0xFF))
break;
<------------------------------ (1) leaves the loop with successful get
call !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
vfdev = pci_get_device(PCI_VENDOR_ID_INTEL,
device_id, vfdev);
}
/*
* There's a slim chance the VF could have been hot plugged,
* so if it is no longer present we don't need to issue the
* VFLR. Just clean up the AER in that case.
*/

e_dev_err("Issuing VFLR to VF %d\n", vf);
pci_write_config_dword(vfdev, 0xA8, 0x00008000);

/*
* Even though the error may have occurred on the other port

* for both of them.

* PROBLEM: BNX2 missing fw file
From: Marco Carlo Spada @ 2012-12-09 10:57 UTC (permalink / raw)
To: netdev
Hi everybody,
few days ago I installed and recompiled kernel release 3.6.9 on an HP Server
ML350g5 with a bnx2 ethernet controller on board.
I¹m using a Slackware64 V.13.37 distro.
After booting up, I could not see the controller.
From ³dmesg² log I noticed that bnx2 driver would load the firmware file
called ³bnx2/bnx2-mips-06-6.2.3.fw², but this file is not present.
I could download it from
³http://git2.kernel.org/?p=linux/kernel/git/firmware/linux-firmware.git;a=tr
ee;f=bnx2;h=78c16645553a90b365391312546ca4e256f271fb;hb=654c70dae35817b6a5f6
dae553c5d4ef38d07195².
=====
It seems to me that the dir contents of /usr/src/linux-3.6.9/firmware/bnx2
are not in sync with the
/usr/src/linux-3.6.9/drivers/net/ethernet/broadcom/bnx2.c source file.
If this can be of some help, I send you here some listings I produced during
the debug analisys I did.
Here are relevant lines from ³dmesg²...

Yes. These (bonding and caif_usb) weren't the only ones, though.

Ok, That makes more sense, thank you. Although I still don't think this is
safe (but the problem may not be solely introduced by this patch). Using a
global limit that assumes the sender will block when the congestion window is
reached just doesn't seem sane to me. It clearly works with the Linux
implementation, as it conforms to your expectations, but an alternate
implementation could create a DOS situation by simply ignoring the window limit,
and continuing to send. I see that we drop frames over the global limit in
filter_rcv, but the check in rx_queue_full bumps up that limit based on the
value of msg_importance(msg), but that threshold is ignored if the value of
msg_importance is invalid. All a sender needs to do is flood a receiver with
frames containing an invalid set of message importance bits, and you will queue
frames indefinately. In fact that will also happen if you send message of
CRITICAL importance as well, so you don't even need to supply an invalid value
here.

No, not logically wrong, but not an optimization either. With this change,
your only use of rx_queue_full passes OVERLOAD_LIMIT_BASE/2 as the base value to
rx_queue_full, and then you do some multiplication based on that. If you really
want to optimize this, leave OVERLOAD_LIMIT_BASE where it is (rather than
doubling it like this patch series does), mark rx_queue_full as inline, and just
pass OVERLOAD_LIMIT_BASE as the argument, it will save you a division opration,
the conditional branch and a call instruction. If you add a multiplication
factor table, you can eliminate the if/else clauses in rx_queue_full as well.

This resolved the deref. Thanks.

for this item: drop_watch does not show any drops (i've disable all
other interfaces for clear env)
I will explain a little bit more the setup:
bnx2x device (under testing) is configured for RSS for IPGRE packets.
Sending multiple (3) TCP_STREAM causes ip_gre interface to disappear
packets (even ICMP).
This is not happening with single TCP_STREAM, or before gro_cell
introduction.
i was searching for the drops by print-out in ip_gre.c but disappeared
packets completes this code:
static int ipgre_rcv(struct sk_buff *skb)
(snip)
printk("%s:%d\n", __FUNCTION__, __LINE__);
tstats = this_cpu_ptr(tunnel->dev->tstats);
u64_stats_update_begin(&tstats->syncp);
tstats->rx_packets++;
tstats->rx_bytes += skb->len;
u64_stats_update_end(&tstats->syncp);
gro_cells_receive(&tunnel->gro_cells, skb);
return 0;
