Thank you for your advices!
But these communities still concentrate on the network applications in
linux. Is there any community mainly about the network itself, such as
how mac layer organized and its protocols?
Thanks very much!

For your application it should not matter WHY the data can be written to
the peer. It can be happened that the peer close the window, some
scheduling bottleneck or whatever else. A blocking socket means for you
that some data is in the pipe, waiting for transmit. This is the knowledge
that you require, and you should deal with it. A blocking socket does not
mean FAILED, a failure is returned via ECONNRESET or otherwise. So
everything is fine when your socket blocks. Probably you should adjust your
Apache timeouts or other parts of the program logic.

No, you should adjust your code and account that the socket has data in
the pipe. That's all.

Exactly this functionality already exists by way of the BROUTING chain
in the broute table. Currently, link-local packets are hardcodedly
treated as local before they even reach that chain. Nick's patch, in
conjunction with BROUTING, provides exactly what you're trying to do.
Now, without bridge netfilter, your patch becomes rather useless while
Nick's patch still allows per-group (and therefore per-protocol)
control.
Further, Nick's patch is considerably less intrusive.
I would therefore ask for Nick's patch to be merged.

This patch removes a piece of code (actually commented)
only useful for some ST platforms in the past.
This kind of setting now can be done by using the platform
callbacks provided in linux/stmmac.h (see the stmmac.txt for
further details).

You're 100 % right, there is a leak here.
(But "ip" or "brctl" commands first check link already exist before
trying create it, so you need to tweak them to actually hit this bug)
We have to add a free_netdev() call to free the net_device.

If you write :
u32 newval = hi(*acc) + val;
if (wrapped)
newval += 65536;
*acc = newval;
C compiler (gcc) is free to eliminate the temp variable and to generate
same code than :
*acc = hi(*acc) + val;
if (wrapped)
*acc += 65536;
ACCESS_ONCE() here is the clean way (and self explanatory/documented) to
keep compiler to write to *acc twice.

* mlx4 throws DMA sync error with CONFIG_DMA_API_DEBUG set
From: Josh Boyer @ 2011-08-22 12:22 UTC (permalink / raw)
To: Yevgeny Petrilin, Roland Dreier; +Cc: David S. Miller, netdev, linux-kernel
The Fedora kernels run with DMA debugging enabled, and we've seen[1] the
mlx4 driver throw a backtrace for trying to sync DMA memory that
lib/dma-debug.c doesn't think it allocated. It seems to stem from
mlx4_write_mtt_chunk calling a sync with &dev->pdev->dev as the device.
I'm not sure whether that is "illegal" or if it's just confusing enough
to the debug code that it throws an incorrect error.
Backtrace from 3.0.1 below, though I believe the code in question is still
basically the same in mainline.

Eric,
I'm wondering why you'd need ACCESS_ONCE() here? Wouldn't using the temp variable (newval) as you suggested,
ensure that the reader doesn't see a half-baked value?

The "write once" is the only requirement.
Something like :
u32 newval = hi(*acc) + val;
if (wrapped)
newval += 65536;
ACCESS_ONCE(*acc) = newval;

Both sets of hardware were using Marvell 88e1116 chips (the r8169 driver).
Interestingly on the hardware I just used to reproduce the fault the
network path is VM1 -> br1 -> eth0 -> DNAT -> br1 -> VM2
On the machine that originally exhibited the fault the network path was
VM1 -> br1 -> ppp0 -> DNAT -> br1 -> VM2
So on the original machine the packet never even goes near a physical
interface.
The problem only exhibited itself if I tried to use the address of eth0
or ppp0 to get to VM2 from VM1. If I went dirctly from VM1 to VM2 using
local addresses and never traversed netfilter it never paniced.
I also agree the patch I identified simply unmasked an underlying issue,
and of course on anything later than the linus 3.0 kernel I can't
reproduce it now anyway.
It's nice to know its fixed, but it'd be nice to know *what* fixed it
rather than it just went away after some code re-factoring.
I did have a perverse thought about doing a bisect between 3.0.0 and
3.1-rc2 to see precisely *what* fixed the problem, but the thought of
another 7 hours of crash and burn is not overly appealing.

This adds a race for lockless SNMP readers (in be_get_stats64())
They can see the 32bit value going backward.
You have to be very careful to read the *acc once, and write it once.

* net_device leak after "bridge: allow creating bridge devices with netlink"?
From: Jan Beulich @ 2011-08-22 11:34 UTC (permalink / raw)
To: shemminger; +Cc: davem, netdev
Stephen,
directly returning the result of register_netdev() from br_add_bridge()
would - to me - appear to be leaking "dev" in case of failure. Or am I
overlooking some implicit mechanism by which this would get freed?
Thanks, Jan

I am not sure what you want to fix.
Fact is the skb has the TCPHDR_PSH, even if tcp_transmit_skb() (or
tcp_fragment()) is/are not able to clone/split it.

* [PATCH net-next 1/5] be2net: Fix race in posting rx buffers.

In-Reply-To: <1314011613-4519-1-git-send-email-sathya.perla@emulex.com>
There is a possibility of be_post_rx_frags() being called simultaneously from
both be_worker() (when rx_post_starved) and be_poll_rx() (when rxq->used is 0).
This can be avoided by posting rx buffers only when some completions have been
reaped.
