It would also be worth explicitly stating that there is no serialisation
of calls to these operations, so drivers may need to use a spinlock in
their implementation. I wrote this description under the mistaken
belief that there was some serialisation, and point 2 reflects that.

Does it still occur if you remove the debug line below?

Hi all,
thanks for the help,
the kernel is a main line kernel. Then yes, i am still using uclinux
tree for libc/tools.
I collected another spinlock recursion with a slightly different call
stack trace, as always, the spinlock recursion issue happen on a high
tx/rx traffic of the dm9000e, in this case just asking an index.html
with some images and texts:

seems like while i transmit a packet, dm9000_interrupt try to acquire
the spinlock owned from the same task.
Compiling the kernel i am getting:
CC kernel/irq/handle.o
kernel/irq/handle.c:432:3: warning: #warning __do_IRQ is deprecated.
Please convert to proper flow handlers
Could the usage of __do_IRQ super-handler be a cause of the issue ?
many thanks,
angelo

Need to make it clear that get_stats is not needed if get_stats64 is defined.

It looks like the comment/documentation in netdevice.h is incorrect.
* struct net_device_stats* (*ndo_get_stats)(struct net_device *dev);
* Called when a user wants to get the network device usage
* statistics. Drivers must do one of the following:
* 1. Define @ndo_get_stats64 to fill in a zero-initialised

If you implement new (64bit) stats, old one is not used at all.
Check net/core/dev.c : dev_get_stats()
If ndo_get_stats64() method is implemented, its called, and legacy
interfaces are ignored.

I think having the VF driver not support the 'set' routines is good enough. This is inline with how we handle other operations not supported by the lower layer device. Adding another bit would work as well but it seems simpler to only add flags that are needed.
Then dcbnl should return EOPNOTSUPP for this case.

So we must also implement to old net_stats interface, for backward

* Re: IPV6 loopback bound socket succeeds connecting to remote host
From: Albert Pretorius @ 2010-12-29 16:53 UTC (permalink / raw)
To: David Miller, Shan Wei; +Cc: netdev, yoshfuji, pekkas, jmorris
In-Reply-To: <4D11A370.9060901@cn.fujitsu.com>
Hi
I tested this on 2.6.37-rc8 but unfortunately that does not address the problem. I suspect the ip_forward.c change only addresses the routing of data when /proc/sys/net/ipv6/conf/all/forwarding is enabled.
The original patch is required to prevent the kernel from sending a packet on the network with a source address of loopback. The kernel should not do that regardless of whether the packet will be dropped by the network (not routed).
Also from an application point of view I believe the behaviour should be the same for IPV4 and IPV6 when binding to loopback and connecting to remote address (i.e. EINVAL).
A further change is required to avoid the kernel acting on the reception of a packet with source address of loopback. Currently it will generate an ICMP6 dest unreachable, or pass the packet to an application listening on that port.
This patch (which includes the previous) seems to addresses the above problems:

So far I can confirm that switching to sbk_copy fixes the crash.

* sysctls below net.ipv[46].conf.all not working as expected
From: Uwe Kleine-König @ 2010-12-29 16:06 UTC (permalink / raw)
To: netdev
Hello,
I did the following:
cassiopeia:~# sysctl net.ipv6.conf.all.use_tempaddr
net.ipv6.conf.all.use_tempaddr = 0
cassiopeia:~# sysctl net.ipv6.conf.eth0.use_tempaddr
net.ipv6.conf.eth0.use_tempaddr = 0
cassiopeia:~# sysctl -w net.ipv6.conf.all.use_tempaddr=1
net.ipv6.conf.all.use_tempaddr = 1
cassiopeia:~# sysctl net.ipv6.conf.all.use_tempaddr
net.ipv6.conf.all.use_tempaddr = 1
cassiopeia:~# sysctl net.ipv6.conf.eth0.use_tempaddr
net.ipv6.conf.eth0.use_tempaddr = 0
Here I would have expected that eth0's use_tempaddr is 1, too. The
problem is not that this entry isn't writeable:
cassiopeia:~# sysctl -w net.ipv6.conf.eth0.use_tempaddr=1
net.ipv6.conf.eth0.use_tempaddr = 1
cassiopeia:~# sysctl net.ipv6.conf.eth0.use_tempaddr
net.ipv6.conf.eth0.use_tempaddr = 1
I got the same results when using net.ipv4.conf.all.rp_filter (and
net.ipv4.conf.eth0.rp_filter resp.)
Is this a bug or just my failure to see how conf/all works?
Best regards
Uwe

Tomas looked into it a bit more and told me that it happens on IPv6
packets. To recap, he gets
kernel BUG at include/linux/skbuff.h:1178!
with
EIP: [<f83edd65>] br_multicast_rcv+0xc95/0xe1c [bridge]
Also remember that the packets are almost fully nonlinear, when they get
here they likely have almost no data in the skb header.
I then looked at br_multicast_ipv6_rcv(), and it looks fishy:
Up to:
skb2 = skb_clone(skb, GFP_ATOMIC);
everything's fine, since ipv6_skip_exthdr() will use
skb_header_pointer(). At this point, offset is the result of
ipv6_skip_exthdr(). Remember that skb_clone() is not skb_copy().
Then, however, we do
__skb_pull(skb2, offset);
At this point, however, I don't see anything that guarantees that all
"offset" bytes are part of the headroom -- and indeed I think this is
where it crashes.
If it didn't crash, because this many bytes were part of the header,
continuing further into the function, however, we could still crash:
if (!pskb_may_pull(skb2, sizeof(*icmp6h)))
goto out;
now makes sure that we can read the ICMPv6 header. Later, however, we do
case ICMPV6_MGM_REPORT:
{
struct mld_msg *mld = (struct mld_msg *)icmp6h;
BR_INPUT_SKB_CB(skb2)->mrouters_only = 1;
err = br_ip6_multicast_add_group(br, port, &mld->mld_mca);
which seems just as unsafe since "mld_mca" need not be part of the
header of the SKB. Similarly in another branch of this.
Additionally, I'm not convinced that there even is guaranteed to be
enough space in the SKB at all for the entire "struct mld_msg".
And finally, the error path in this function is confusing. Below patch
should be fine since unlike IPv4 (where this was copied maybe?) this
code unconditionally clones the SKB.

* [PATCH net-2.6] starfire: Fix dma_addr_t size test for MIPS
From: Ben Hutchings @ 2010-12-29 14:26 UTC (permalink / raw)
To: David Miller, Ion Badulescu; +Cc: Akinobu Mita, FUJITA Tomonori, netdev
Commit 56543af "starfire: use BUILD_BUG_ON for netdrv_addr_t" revealed
that the preprocessor condition used to find the size of dma_addr_t
yielded the wrong result for some architectures and configurations.
This was kluged for 64-bit PowerPC in commit 3e502e6 by adding yet
another case to the condition. However, 64-bit MIPS configurations
are not detected reliably either.
This should be fixed by using CONFIG_ARCH_DMA_ADDR_T_64BIT, but that
isn't yet defined everywhere it should be.
Signed-off-by: Ben Hutchings <ben@decadent.org.uk>
---
The MIPS conditions are changed to match those Tomonori specified for
CONFIG_ARCH_DMA_ADDR_T_64BIT.
Please change the condition to defined(CONFIG_ARCH_DMA_ADDR_T_64BIT) in
net-next-2.6. I leave it up to you to decide when to make that change.
(Simply applying a patch to net-next-2.6 now will result in a later
merge conflict and breakage for those two architectures.)
Ben.

John,
Since I need to modify my patches I can resubmit them on top of your

I see your point, I like DCB_CAP_DCBX_LLD_MANAGED better. I will change
it an resubmit the patches. DCB_CAP_DCBX_HW implies 3 things:
1. DCBX negotiation is managed by some other entity.
2. The user can use the 'get' routines to get the negotiation results.
3. The user can use the 'set' routines to set the initial configuration
for the negotiation.
I think No 3. is irrelevant to VFs, that is you don't want multiple VF
drivers trying to change the initial configuration settings. I can think
of 2 ways to make this distinction, the first is for the VF driver not
to support the 'set' routines (or always return an error value). The
second is to add another attribute flag: DCB_CAP_DCBX_LLD_CFG which will
indicate exactly No 3. while DCB_CAP_DCBX_LLD_MANAGED will indicate No
1. and 2. The VF driver will declare DCB_CAP_DCBX_LLD_MANAGED only and a
driver for an embedded DCBX engine will declare both flags. What do you
think?
Thanks
Shmulik.

* [PATCH v2] tg3: fix return value check in tg3_read_vpd()

Besides -ETIMEDOUT and -EINTR, pci_read_vpd may return other error
values like -ENODEV or -EINVAL which are ignored due to the buggy
check, but the data are not read from VPD anyway and this is checked
subsequently with at most 3 needless loop iterations. This does not
show up as a runtime bug.

Although pci_read_vpd returns ENODEV directly, there is a call to vpd->read
function which may return other error values and is eg. set to
pci_vpd_pci22_read() :
drivers/pci/access.c::pci_vpd_pci22_read()
may return -EINVAL or -EINTR directly
or -ETIMEDOUT or -EINTR via pci_vpd_pci22_wait()
Yes, other negative values besides ETIMEDOUT and EINTR are ignored and after
3 attempts the pos != TG3_NVM_VPD_LEN check goes outwards. The fixed version
allows to jump out immediately. So this does not manifest itself as a
misbehaviour at runtime. It was found by code analysis.
I'll post updated patch.
