LBA28/LBA48 off-by-one bug in ata.h
PATCH 1/1 LBA28/LBA48 off-by-one bug in ata.h
Hi.
I recently bought 3 HGST P7K500-series 500GB SATA drives and had trouble accessing the block right on the LBA28-LBA48 border. Here's how it fails (same for all 3 drives):
# dd if=/dev/sdc bs=512 count=1 skip=268435455 > /dev/null
dd: reading `/dev/sdc': Input/output error

# dmesg

ata1.00: status: { DRDY ERR }
ata1.00: error: { ABRT }
ata1.00: configured for UDMA/33
ata1: EH complete
...After some investigations, it turned out this seems to be caused by misinterpretation of the ATA specification on LBA28 access. Following part is the code in question:
=== include/linux/ata.h ===
static inline int lba_28_ok(u64 block, u32 n_block)
{
/* check the ending block number */
return ((block + n_block - 1) < ((u64)1 << 28)) && (n_block <= 256);
}HGST drive (sometimes) fails with LBA28 access of {block = 0xfffffff, n_block = 1}, and this behavior seems to be comformant. Other drives, including other HGST drives are not that strict, through.
Quoted 1 line
From the ATA specification:
(http://www.t13.org/Documents/UploadedDocuments/project/d1410r3b-ATA-ATAPI-6.pdf)
8.15.29 Word (61:60): Total number of user addressable sectors This field contains a value that is one greater than the total number of user addressable sectors (see 6.2). The maximum value that shall be placed in this field is 0FFFFFFFh.
So the driver shouldn't use the value of 0xfffffff for LBA28 request as this exceeds maximum user addressable sector. The logical maximum value for LBA28 is 0xffffffe.
The obvious fix is to cut "- 1" part, and the patch attached just do that. I've been using the patched kernel for about a month now, and the same fix is also floating on the net for some time. So I believe this fix works reliably.
Just FYI, many Windows/Intel platform users also seems to be struck by this, and HGST has issued a note pointing to Intel ICH8/9 driver.
"28-bit LBA command is being used to access LBAs 29-bits in length"
http://www.hitachigst.com/hddt/knowtree.nsf/cffe836ed7c12018862565b000530c74/b531b8bce8745fb78825740f00580e23
Also, *BSDs seems to have similar fix included sometime around ~2004, through I have not checked out exact portion of the code.
I do not subscribe to the list, so Cc: me if further discussion is needed.

...I'm surprised to see the above. We do lots of dd to raw SATA drive activity with a large variety of drives. Both reads and writes and we've never noticed this issue.
Does it happen if you are using 4k blocks with dd?
ie. We typically read / write the entire drive but using 4k blocks.
In fact a few months ago we specifically bought about 15 drives of various sizes and manufacturers and verified that we could both read and write all of the sectors of the drives.

Taisuke,
I'd like to reproduce your results and keep the drive as a test drive to ensure our systems work properly across the entire spectrum of drives.

From our earlier tests we had a Hitachi 7K1000 Series Model
HDS721075KLA330 SATA 750GB drive, but it is not exhibiting the problem you describe.
Can you tell me a specific Model number Hitachi drive that the current linux kernel is failing with.
Thanks

Greg,
Thanks for responding and excuse me for the delay in reply.
# This is a re-post as I had email server configuration issue. # Excuse me if you receive similar messages twice.
I was finally able to stop the machine, and took out 1 of 3 drives in question. I re-tested the drive, and the issue reproduced 100%. Here's the model/serial code of the drive:
# output from "scsiinfo -a /dev/sda"
Vendor: ATA
Product: Hitachi HDP72505
Revision level: GM4O
Serial Number ' GEB531RE0GEPGB' From the information I have gathered, this issue seems to be
either environment or usage-dependent. It seems it always reproduces, or never happens. While I see many reports (and reports of "-1" fix working) on various blogs/BBSs, I do also see many saying "doesn't happen with me".
I must admit this weakens my proposal to apply the patch. However, althrough it may not be 100% reproducible everywhere at this time, I believe there is at least an ambiguity in the spec ("How should ATA req on 0xfffffff be handled?") which could cause driver to fail anytime, and so decided to submit a patch.
The fact *BSDs (and probably Intel) having similar fix also pushed me to take action, and I'd also like to clarify that I'm not the only one with this "-1" fix - the exact same stuff has been floating on the net for months.
Now I have the drive at hand, I re-tested with latest 2.6.25.3 kernel (rebuilt from vanilla source, not some distribution kernel), and here's the result:
# uname -a
Linux pc 2.6.25.3 #2 Thu May 15 01:05:14 JST 2008 i686 GNU/Linux

error)
ata3.00: status: { DRDY ERR }
ata3.00: error: { ABRT }
ata3.00: configured for UDMA/33
ata3: EH complete
...[same messages repeating several times]...And for block size of 1KB-8KB, I get exactly the same error:
# dd if=/dev/sda bs=1024 count=1 skip=134217727 dd: reading `/dev/sda': Input/output error # dd if=/dev/sda bs=2048 count=1 skip=67108863 dd: reading `/dev/sda': Input/output error # dd if=/dev/sda bs=4096 count=1 skip=33554431 dd: reading `/dev/sda': Input/output error # dd if=/dev/sda bs=8192 count=1 skip=16777215 dd: reading `/dev/sda': Input/output error # dd if=/dev/sda bs=16384 count=1 skip=8388607 dd: reading `/dev/sda': Input/output error
Now, here's more interesting behavior of the drive. With enough "backoff" from the border, the drive responds normally to the request:
# dd if=/dev/sda bs=4096 count=1 skip=33554431 dd: reading `/dev/sda': Input/output error 0+0 records in 0+0 records out 0 bytes (0 B) copied, 0.288113 s, 0.0 kB/s # dd if=/dev/sda bs=4096 count=2 skip=33554430 dd: reading `/dev/sda': Input/output error 1+0 records in <----------------------------- PARTIAL READ OK 1+0 records out 4096 bytes (4.1 kB) copied, 0.309428 s, 13.2 kB/s # dd if=/dev/sda bs=4096 count=3 skip=33554429 3+0 records in <----------------------------- FULL READ OK 3+0 records out 12288 bytes (12 kB) copied, 0.00753634 s, 1.6 MB/s # dd if=/dev/sda bs=4096 count=100 skip=33554429 100+0 records in 100+0 records out 409600 bytes (410 kB) copied, 0.00551966 s, 74.2 MB/s
And the same test with 512-byte block request:
# dd if=/dev/sda bs=512 count=1 skip=268435455 dd: reading `/dev/sda': Input/output error 0+0 records in 0+0 records out 0 bytes (0 B) copied, 0.289812 s, 0.0 kB/s # dd if=/dev/sda bs=512 count=2 skip=268435454 dd: reading `/dev/sda': Input/output error 0+0 records in 0+0 records out 0 bytes (0 B) copied, 0.28924 s, 0.0 kB/s ... ...continue backing off with larger total access size... ... # dd if=/dev/sda bs=512 count=8 skip=268435448 dd: reading `/dev/sda': Input/output error 0+0 records in 0+0 records out 0 bytes (0 B) copied, 0.286469 s, 0.0 kB/s # dd if=/dev/sda bs=512 count=9 skip=268435447 dd: reading `/dev/sda': Input/output error 1+0 records in <----------------------------- PARTIAL READ OK 1+0 records out 512 bytes (512 B) copied, 0.322541 s, 1.6 kB/s ... ...continue backing off with larger total access size... ... # dd if=/dev/sda bs=512 count=16 skip=268435440 dd: reading `/dev/sda': Input/output error 8+0 records in <----------------------------- MORE PARTIAL READ OK 8+0 records out 4096 bytes (4.1 kB) copied, 0.327491 s, 12.5 kB/s # dd if=/dev/sda bs=512 count=17 skip=268435439 17+0 records in <----------------------------- FULL READ OK 17+0 records out 8704 bytes (8.7 kB) copied, 0.0119018 s, 731 kB/s # dd if=/dev/sda bs=512 count=100 skip=268435439 100+0 records in 100+0 records out 51200 bytes (51 kB) copied, 0.00237427 s, 21.6 MB/s
I'm starting to see some pattern here...
So even if request goes over LBA address of 0xfffffff, it seems it won't break if certain amount of request (8KB>) is sent prior to accessing the border.
I have attached full log of the test (pctest.sh, pctest.log), so please check it out if there's anything unclear with above excerpt. Also, as this could be some hardware and/or software combination issue, reports generated by lshw(1) and scsiinfo(1) are also attached.
Is there any other tests I can do to track down the issue? Maybe sending raw LBA28 request directly to the drive may help to identify the issue?

Jeff,
I never saw the below acked or nacked. I don't see it in 2.6.27-rc3-next.
Did you have any thoughts?

Hi.
I recently bought 3 HGST P7K500-series 500GB SATA drives and had trouble accessing the block right on the LBA28-LBA48 border. Here's how it fails (same for all 3 drives):
# dd if=/dev/sdc bs=512 count=1 skip=268435455 > /dev/null dd: reading `/dev/sdc': Input/output error 0+0 records in 0+0 records out 0 bytes (0 B) copied, 0.288033 seconds, 0.0 kB/s # dmesg ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0 ata1.00: BMDMA stat 0x25 ata1.00: cmd c8/00:08:f8:ff:ff/00:00:00:00:00/ef tag 0 dma 4096 in res 51/04:08:f8:ff:ff/00:00:00:00:00/ef Emask 0x1 (device error) ata1.00: status: { DRDY ERR } ata1.00: error: { ABRT } ata1.00: configured for UDMA/33 ata1: EH complete ...After some investigations, it turned out this seems to be caused by misinterpretation of the ATA specification on LBA28 access. Following part is the code in question:
===
include/linux/ata.h===
static inline intlba_28_ok(u64 block, u32 n_block){ /* check the ending block number */ return ((block + n_block - 1) < ((u64)1 << 28)) && (n_block <= 256);}
HGST drive (sometimes) fails with LBA28 access of {block =
0xfffffff,n_block= 1}, and this behavior seems to be comformant. Other drives, including other HGST drives are not that strict, through.From the ATA specification:
(http://www.t13.org/Documents/UploadedDocuments/project/d1410r3b-ATA-ATAPI-6.pdf)8.15.29 Word (61:60): Total number of user addressable sectors This field contains a value that is one greater than the total number of user addressable sectors (see 6.2). The maximum value that shall be placed in this field is 0FFFFFFFh.
So the driver shouldn't use the value of
0xffffffffor LBA28 request as this exceeds maximum user addressable sector. The logical maximum value for LBA28 is0xffffffe.The obvious fix is to cut "- 1" part, and the patch attached just do that. I've been using the patched kernel for about a month now, and the same fix is also floating on the net for some time. So I believe this fix works reliably.
Just FYI, many Windows/Intel platform users also seems to be struck by this, and HGST has issued a note pointing to Intel ICH8/9 driver.

By a very strict pessimal reading of the spec I would agree with you

I'm happy with this Jeff and I think it should go in promptly (didn't realise it hadn't done so before). Whether the -1 is right could be argued in debate about fine points of the spec but it has no real impact to do this and if drives actually care about this in some cases we clearly should.
