You can see in ks_rcv function,
ks->frame_cnt = ks_rdreg16(ks, KS_RXFCTR) >> 8;
so "RXFC RX Frame Count" is a byte, maximum 256 total frames.
but we have the threshold ..
As you can see also in ks_setup the
/* Setup Receive Frame Threshold - 1 frame (RXFCTFC) */
ks_wrreg16(ks, KS_RXFCTR, 1 & RXFCTR_THRESHOLD_MASK);
In conclusion what happen is that if we stop system interrupts for a while,
when we are back the ks_rcv function starts reading the frames, and
the
while (ks->frame_cnt--) {
..
frame_hdr++;
}
loop goes out of the malloc'ed area.
We experienced so strange bugs in the last weeks that we are so happy that it seems fixed, but I need
some weeks to confirm it is robust enough.
The 'load setup' is like the following:
- nfs rootfs
- host $ sudo ping -f $TARGET_IP_ADDRESS
- host $ scp -r BIG_DIR user@$TARGET_IP_ADDRESS:
But I'm not sure to create the bug in a mathematical way, it seems to depend on packets on the corporate lan.
Surely if I stop with jtag and restart after some seconds I have buffer overflow, with same errors in ram that I
obtain randomically with 'load setup'.
Hoping it helps,
Raffaele

Sure it does.
So the limit should be 255, not 256.
(0xFFFF >> 8 -> 0xFF)
ks->frame_cnt = ks_rdreg16(ks, KS_RXFCTR) >> 8;
I cant see how 256 can be stored in a 8bit field ?
You see, explaining things in Changelog can actually help a lot, since
we now understand chip has this 8bit limit for the frame counter.

linux-next-cherry-picks/0007-mac80211-handle-non-bufferable-MMPDUs-correctly.patch
is to be blamed for. This is fixed, new tarball:
http://www.orbit-lab.org/kernel/compat-wireless-3-stable/v3.3/compat-wireless-3.3-2-n.tar.bz2
sha1sum: dd18cfabbe705a75440fd7fbe50a09d5fe34bb70
Thanks for reporting this. Just FYI -- I am working to use ckmake on
compat-wireless.git to build test against all supported kernels prior
to release just as I am doing now for compat.git, but the current
development cycle still a few items which require a bit of work to
backport to fix compilation against older kernels. That is the goal
though, so that future releases area always guaranteed to compile
against all supported stable kernel releases listed on kernel.org.

* [PATCH net-next v2 1/5] r8169: modify pll power function
From: Hayes Wang @ 2012-03-28 8:26 UTC (permalink / raw)
To: romieu; +Cc: netdev, linux-kernel, Hayes Wang
Adjust r810x_pll_power_down, r810x_pll_power_up, and r8168_pll_power_up.
Always power up device during rtl_open. For r810x, turn off more power
when the WOL is disabled.

* suspicious RCU usage warnings in 3.3.0
From: Meelis Roos @ 2012-03-28 8:45 UTC (permalink / raw)
To: Linux Kernel list, netdev
This v3.3 release running on sparc64 UP (Sun Fire V100). Today I noticed
it has gotten a bunch on RCU warnings from different netowrk-related
places. Some are from tulip irq's, some are from network-related
softirqs.
Is this the same RCU problem that was fixed after 3.3 (fix a potential
rcu_read_lock() imbalance in rt6_fill_node())? My problem does not seem
to be ipv6-only, most traces are from IPv6 but some for ip.

David, thanks for your feedback! So here's a small rework of the patch:
If both addresses equal, nothing needs to be done. If the device is down,
then we simply copy the new address to dev->dev_addr. If the device is up,
then we add another loopback device with the new address, and if that does
not fail, we remove the loopback device with the old address. And only
then, we update the dev->dev_addr.

You never need to ask me these kinds of questions, you can
either check my GIT tree or look at:

you're right, we'll resend the patch with 255.
Well actually, since the chip appears to have 12K of internal rx buffers
and the shortest ethernet frame should be 64 bytes long, maybe the limit could
be set to 12*1024/64 = 192 frames, but I think 255 is safer.

I wouldn't mind if you credited me given that your patch now is based on my fix
and analysis. ;-)

I'm asking because drivers/usb/gadget/ should either go through me or
you should wait for my Acked-by. Now it's too late for that, but next
time for my Ack.
