zd1211rw (2.6.26 sparc64): unaligned access (zd_mac_rx)

Hi,

You may remember I reported a similar problem almost a year ago:

http://marc.info/?l=linux-wireless&m=119543627712471&w=2

I've never given up hope that the issues could be worked through. So 
I've made a fresh attempt at getting the zd1211rw working under 
sparc64-linux.

As per the previously employed strategy, I have successfully built a 
2.6.26 kernel for sparc64, by taking the configuration for the Debian 
build of this kernel, and additionally configuring the zd1211rw driver. 
I have attached the .config. Note, thinking it might be usefully, I 
enabled CONFIG_ZD1211RW_DEBUG just in case.

I am successfully able to modprobe the driver (in fact, I think it is 
being probed during the boot, as whatever magic effects this kicks in). 
Here is the dmesg output:

[   57.840661] zd1211rw usb_init()
[   57.840933] usb 4-3: print_id() 6891:a727 v4330 high
[   57.950264] usb 4-3: reset high speed USB device using ehci_hcd and 
address 2
[   58.195856] zd1211rw 4-3:1.0: zd_chip_read_mac_addr_fw()
[   58.198901] phy0: Selected rate control algorithm 'pid'
[   58.854432] zd1211rw 4-3:1.0: probe() successful
[   58.854451] zd1211rw 4-3:1.0: phy0
[   58.902168] usbcore: registered new interface driver zd1211rw
[   58.978077] zd1211rw initialized

At this point, I have not touched a wireless-tools tool, and to be sure 
that the problems are not sourced from them, I do not use them.

Instead, I attempt to bring up the interface, by doing:

$ sudo ifconfig wlan0 up

Immediately after executing this command, I start getting console 
messages that report the problems I am reporting in this email. I have 
executed a dmesg, and copied the relevant lines into a separate file 
attached as dmesg.txt (as this may be too big to inline here). Please 
note, a message like:

[  282.300681] Kernel unaligned access at TPC[10129b68] 
zd_mac_rx+0x144/0x32c [zd1211rw]

periodically is reported even after the ifconfig command completes 
(seemingly successfully).

Thanks in advance for your assistance,
Shaddy

my best bet is this:

        fc = *(__le16 *)buffer;

could you try something with get_unaligned? Though if this is it,

A few lines before that:
|         buffer += ZD_PLCP_HEADER_SIZE;

and ZD_PLCP_HEADER_SIZE is 5 so we end up unaligned, don't we?

This still does semantically change the code.
fc is supposed to be LE and is used as LE in the following code.

So you say we need a get_unaligned() here. Okay. 
A few lines before that, in filter_ack() we dereferance the same
position. filter_ack() is used once and probably inlined so I guess
that's the address where the unaligned access occurs.

Depends where the buffer was before, and thought has gone into this
alignment stuff here so it shouldn't. Might well be a new bug though.

After applying this patch, things seem better. I can associate to an 
open access point, get an IP address and even ping.

However on association, I am still seeing:

and when I start pinging the AP, this starts chiming in:

I also cannot get a full scan with:

iwlist wlan0 scanning

I get about 4 APs (I know there's more) then a bus error. This may be 
related to a similar problem that I was assisted with in my first round 
of posts last year, with regards to the wireless-tools. Perhaps the 
patches still haven't made it downstream?

Thanking you for help,
Shaddy

On my x86_64 box the address of the buffer pointer right after the add
of ZD_PLCP_HEADER_SIZE is:
[   28.462273] buffer: ffff88003e310005

so it looks to me like it was perfectly aligned before the add. Is it
possible that it is not a new bug and we need a get_unaligend helper
here?

Possible, yeah, maybe before we only saw problems with the IP alignment
and somehow this shows up now. Not sure. Anyway, if that fixes it,
obviously we want such a patch :)

I'm keen on troubleshooting this myself. Could you please tell me how I 
can get a disassembly intermixed with source. An objdump -S ./zd1211rw.o 
is not doing the job. I'd rather not re-compile the whole kernel if 
possible, because it takes long. Should I rm the file, do a build, take 
the command line and substitute -g for any -O option?

TIA,
Shaddy

Johannes, thank you for the tip. It's helped me no end.

So, looking into this problem, I was able to come up with a patch 
(attached. Note, it also includes remnants of the patch recommended by 
Sebastian Andrzej Siewior in 
http://marc.info/?l=linux-wireless&m=122493409906326&w=2). The problem

the patches recommended to me way back last year 
(http://marc.info/?l=linux-wireless&m=119543627712471&w=2) also dealt 
with this problem.

Looking into how it was solved then, all the compare_ether_addr() calls 
were replaced with memcmp() calls. This is what I have done with my 
patch as well... but this approach did not fill me with confidence. It 
seemed to me like a quick fix that didn't directly address the alignment 
problem. And IMO my subsequent findings confirm this.

I now hit the following kernel errors:

Looking into this, and the underlying problem is again 
compare_ether_addr(). Now, I'm sure that replacing this with a memcmp() 
is now treading on more toes than just zd1211rw users. And for this 
reason, I think a better solution is going to be required.

Does that sound right? I will persist in trying to understand the code 
to try and come up with a fix. But obviously, I hope that I can get help 
with this to make the former an education exercise, not a kernel

Yes, I think you're right, it appears that the 802.11 header isn't
aligned on a 2-byte boundary, which is extremely strange. Can you, with
your patch applied, do something like

	printk(KERN_DEBUG "%p\n", skb->data);

before this code in zd_mac.c:

        memcpy(skb_put(skb, length), buffer, length);

        ieee80211_rx_irqsafe(hw, skb, &stats);

Sorry, I missed your second mail. (btw, if you generate patches with -p
in diff arguments it helps a bit reading them)

Ok so it looks like the buffer you're getting is unaligned. This is
strange, but I'm too unfamiliar with the code. It seems that there's the
PLCP 5 byte header in front. Well, try the printk I asked for, because
at that point zd1211 should avoid "leaking" the alignment problem.

I think this requires a comment in the code why we do not use
compare_ether_addr() at this place. Something like:

/* We use memcmp() instead of compare_ether_addr(), because the
 * packet might not be 4-byte aligned, yet. This is done later. */

zd1211rw has some code to align the packet to a 4-byte boundary.
But the compare_ether_addr() and the other le16 accesses are done before
that realignment.
This these blow up if (ieee80211_is_data_qos(fc) ^ ieee80211_has_a4(fc))

I have done this... but I think that there is too much output to place 
here. What I can tell you with confidence is that every value is 4-byte 
aligned.

However, I modify filter_ack() in zd_mac.c so that the code looks like this:

         for (skb = q->next; skb != (struct sk_buff *)q; skb = skb->next) {
                 struct ieee80211_hdr *tx_hdr;

                 tx_hdr = (struct ieee80211_hdr *)skb->data;
         printk(KERN_DEBUG "%s:%u: skb %p skb->data %p tx_hdr->addr2 %p 
rx_hdr->addr1 %p\n", __FILE__, __LINE__, skb, skb->data, tx_hdr->addr2, 
rx_hdr->addr1);
                 //if (likely(!memcmp(tx_hdr->addr2, rx_hdr->addr1, 
ETH_ALEN)))
                 if (likely(!compare_ether_addr(tx_hdr->addr2, 
rx_hdr->addr1)))
                 {

(note, I re-instated the compare_ether_addr() so that I could be sure 
that the unaligned access corresponded with whatever values I was seeing 
in the print).

Here is the output of the first print from this location that I see in 
syslog:

Nov 10 00:47:17 trad kernel: [ 8239.534950]

So you can see that skb->data is not even 2-byte aligned. And my debug 
leads me to believe that the problem is this line in zd_mac_tx_to_dev():

                  skb_pull(skb, sizeof(struct zd_ctrlset));

A before and after of this line gives me this output:

Nov 10 00:47:17 trad kernel: [ 8239.534065] 
drivers/net/wireless/zd1211rw/zd_mac.c:376: skb fffff8003d0d8fc0

drivers/net/wireless/zd1211rw/zd_mac.c:390: skb fffff8003d0d8fc0 
skb->data fffff8003d874cdb

Perhaps there needs to be some padding there?

Also, I've just had a look at the git version of zd_mac.c, and I notice 
it is all change there again. I would feel uncomfortable having studied 
the 2.6.26 code to have to start again. Is it expected that I use the 
latest available via git?

Thanks in advance,
Shaddy

Well, yes, however, then his patch should have fixed the whole thing,
which it didn't.

Ok, after a long hard slog at trying to understand all this, I'm going 
to have to pause the effort. I am beginning to understand the mechanisms 
in place... however, I am not totally sure about anything. My first 
impression though is that before control is even passed to the driver 
via zd_op_tx(), alignment issues have already hit. As far as I could 
tell, at that stage skb->data can already be on an odd byte boundary.

Now, all this is very confusing to me... largely because I don't fully 
understand what an SKB is. However, it would seem to me that the 
sunlance driver would use this mechanism as well, and AFAICT, that 
driver (even if it isn't a wireless driver) does not suffer from 
alignment issues.

I have much digging left... but I would greatly appreciate the offering 
of opinions as to whether this problem lies deeper in the kernel than 
the zd1211rw driver itself. I get a sense that I'm being a little 
disengaged... but that's totally cool. I understand the onus of at least 
trying to contribute a fix myself.

Devoting a little bit of time here and there to understanding the 
unaligned accesses, I think I understand a whole lot better now.

First off, I only came to realise that the reason the module seemed to 
continue operations despite reporting the unaligned access error was 
because the exception handler actually emulates the intended operation 
(albeit much slower). Good to know.

I then came to understand that we cannot expect alignment on RX in the 
zd1211rw module. In fact, we might expect that 80211 packets are always 
unaligned, because the 5 byte PLCP prefix in the SKB buffer will always 
push it into an odd address (assuming the SKB buffer is allocated 
aligned). In which case, as detailed in the 
Documentation/unaligned-memory-access.txt, replacing 
compare_ether_addr() with memcmp() is perfectly fine.

After solving that, I was still getting an unaligned access from a 
compare_ether_addr() call in sta_info_get() from mac80211 module. My 
dilemma was whether that module would expect alignment always, in which 
case the same simple function replacement would not be OK. But I saw 
several places where memcmp() is preferred to compare_ether_addr(), 
which I assume indicates that mac80211 does not expect alignment of 
80211 packets passed to it.

Applying Sebastian Andrzej Siewior wireless/zd1211rw: use 
get_unaligned_le16 helper (v2) patch and my two changes quietens down 
the kernel completely. I will submit these two patches in follow up emails.

It is interesting (at least to me) to note that a change between kernel 
versions 2.6.26 and 2.6.28-rc6 fixed something that allowed WPA2 to work 
on sparc64. At least according to my careful verification. Perhaps one 
day, I'll narrow that change down.

Shaddy

I think this should be:

	fc = get_unaligned((__le16 *)buffer);

As ieee8011_is_data_qos wants a le16 and your use above will swap to cpu-order.

OK.

So the first hunk needs changing, but other than that, looks OK.

The whole networking stack expects 4byte alignment and the driver _must_
make sure it is this way. Either by padding a constant number of bytes at the front
of each allocated SKB, or (if the alignment differs) use dynamic checks
for the lowest few bits of the pointer passed to mac80211.

Right. But I'm not sure that in this case that the packet is being 
passed to mac80211 by the driver. My recall of the stack traces I saw 
were that the unalignment I was seeing in sta_info_get() were a 
consequence of transmission attempts.

I must admit though, I could not source where the unaligned packet came 
from, as I do not fully understand the different queuing mechanisms in 
use and where and how enqueues occur. My  limited efforts to understand 
this gave me the impression that network stack itself, and not the 
driver, was constructing these unaligned packets, for transmission.

The memcmp() that really persuaded me to believe that the mac80211 had 
no alignment requirements was this one:

net/mac80211/tx.c:1304:		if (memcmp(odev->dev_addr, hdr->addr4, 
ETH_ALEN) != 0)

I would have thought it would use compare_ether_addr() if we could 
safely assume alignment. In any case, say that alignment was always the 
intention... then can't we just use memcmp() as a hack (not being 
derogatory. Just that it would turn into a hack in deference to using 
compare_ether_addr()) consistent with hacks like the above? Even in the 
interim until a program to iron out alignment is set in place?

Shaddy

You're looking at the TX path, that's irrelevant :)

No, the IP stack assumes alignment. Besides, zd1211 actually enforces
the alignment before passing the skb off to mac80211.

Do you mean by that the code that handles TX does not expect alignment?

I suspect I still missing some important point. But here it goes. 
Although the sta_info_get() function seems to be a more general purpose, 
the unaligned access is happening on TX. I found the stack trace:

You mean on RX, right? I'm OK on RX I think. The memcmp() is fine in 
filter_ack(), because it is on the raw packet that comes in from over 
USB which will always be unaligned (because of PLCP header, from the 
device itself). And it is before we actually memcpy() aligned into the 
skb buffer to pass to mac80211.

Perhaps I'm second guessing a little too much here, so I'll ask a simple 
question. Why do I get a 80211 packet passed into 
__ieee80211_tx_prepare() which is at an odd address in the skb buffer? I 
would have expected that they would have always been constructed aligned?

Thanks in advance,
Shaddy
