[PATCH 0/3] increase skb size to prevent dma over skb boundary

[PATCH 0/3] increase skb size to prevent dma over skb boundary

[Neil Horman]

Hey all-
	I was tracking down a memory corruptor lately in which, with DEBUG_SLAB
enabled we were getting several redzone violoations, which was always followed
by an oops in the rx receive path when using the e1000e driver.  Looking at the
cores, the slabs that had their redzone violated were always adjacent to a
size-2048 slab which was allocated by __netdev_alloc_skb.  Doing some
instrumentation led me to see the following.  When the e1000e driver sets up its
rctl register, which defines the length of each of the buffers in the rx ring,
we do this:

switch (adapter->rx_buffer_len) {
        case 256:
                rctl |= E1000_RCTL_SZ_256;
                rctl &= ~E1000_RCTL_BSEX;
                break;
        case 512:
                rctl |= E1000_RCTL_SZ_512;
                rctl &= ~E1000_RCTL_BSEX;
                break;
        case 1024:
                rctl |= E1000_RCTL_SZ_1024;
                rctl &= ~E1000_RCTL_BSEX;
                break;
        case 2048:
        default:
                rctl |= E1000_RCTL_SZ_2048;
                rctl &= ~E1000_RCTL_BSEX;
                break;
        case 4096:
                rctl |= E1000_RCTL_SZ_4096;
                break;
        case 8192:
                rctl |= E1000_RCTL_SZ_8192;
                break;
        case 16384:
                rctl |= E1000_RCTL_SZ_16384;
                break;
        }
}

This is problematic since rx_buffer_len is set to 1500, which causes the rctl
value to fall into the default case, which configures the hardware to think it
can dma up to 2048 bytes into each buffer, despite the fact that the buffer is
only 1500 bytes long.  If we receive a frame that is longer than 1500 bytes,
then the dma will overrun the 1500 byte limit of the sk_buff's data block
spilling into the skb_shared_info structure (which is placed immediately after
the end of the skb->end pointer (or at skb->head + skb->end if
NET_SKBUFF_DATA_USES_OFFSET is configured).  In either case, the spillover
corrupts the skb_shared_info structure, and sets us up for any number of
subsequent corruptions/oopses/failures.  I've fixed this by normalizing the
rx_buffer_length value in the setup_rctl function, which rounds up the length to
the configured value of rctl, forcing us to allocate buffers of a size that meet
the hardwares configuration needs. 

I've tested this on e1000e and confirmed that it fixes my redzone violations and
the observed oops.  Visual inspection indicates that e1000 and ixgb also need
this fix.  I've not explicitly tested them though, so I've split this into three
separate patches

Neil

thought there was an ilog2() call in the kernel to do something like
this? see linux/log2.h. will also make it easier to switch on the
result if you've got a value in bit-position instead of size.

You could use roundup_pow_of_two() instead.

You should return (match >> 1), which is the largest size possible. (Which
is exactly what you need here).

If you modify rx_buffer_len anyway, then get rid of normed_rx_len and
do a quick

    adapter->rx_buffer_len = normalize_rx_len(adapter->rx_buffer_len);

instead. With the modification above, it never fails, so no need to check
for !normed_rx_len.

But I don't really know the context of this change. Is it okay to shorten
rx_buffer_len here? Why was it not set appropriately as the driver
expects?

Oh, BTW, the default case in the switch statement is stupid and should
be removed.

I'll just wash this all out, based on your comments, ben's and Michals, its not
needed..

Agreed, by using roundup_pow_of_two as was previously suggested the extra
variable is no longer needed.

We're not shortening, we're rounding up.  And yes its both ok, and necessecary.
The problem (from the intial email I sent), was that this driver tells the
hardware that potentially it can dma up to X bytes to a given rx buffer, but it
is possible and likely that we only provide Y bytes to dma to, where X > Y.
This leads to corruption of the skb_shared_info structure.

I agree, its silly, but with the above changes, it becomes needed (or beneficial
again), to catch cases in which roundup_pow_of_two returns a value beyond what
the hardware can handle.  I think in this case we should just panic, as
rx_buffer_len should never be larger than 16384.

Sorry to reply to myself, but given the comments regarding the e1000 driver, I

Since the Intel folks are very responsive, I let all Intel driver

Hi Neil,

I am trying to test the patches you submitted (thanks btw) and so far am not able to reproduce the panic you described. When MTU is at 1500 RCTL.LPE (bit 5) is set to 0 and the HW will not allow the reception of large packets (>1522 bytes, which is what rx_buffer_len is set to). This is basically what I am seeing in my tests - packets are discarded by the HW.

Can you provide more details about the setup you used? Steps to reproduce and also details (lspci -vvv, ethtool -e, ethtool -d) of the HW you used and kernel config should help as well.

Thanks,
Emil

When MTU is at 1500 RCTL.LPE (bit 5) is set to 0 and the HW will not allow the reception of large packets (>1522 bytes, which is what rx_buffer_len is set to). This is basically what I am seeing in my tests - packets are discarded by the HW.

Interestingly, the only time we could observe the errors was when SLAB_DEBUG was
configured, so my guess is timing plays an important role.  The problem also
only reproduced on hp-z200 series systems (with e1000e cards in them having pci
vendor device ids  14e4:1684), so perhaps this is restricted to certain hardware
revisions?

Basically I ran a kernel with CONFIG_SLAB_DEBUG turned on on one of the above
systms, and ran the connectathon suite on it.

I don't have access to the system at this minute but, I'll reserve it as soon as
I'm able and dig up the full lspci dump and ethtool info for you.

I will point out though, that in e1000_change_mtu for all the drivers I've
posted modifications for, this normalization of rx_buffer_len is already done,
so there seems to be some precident for doing this operation.

Heres the data you asked for.  The config isn't exact, as the system in question
was installed a few times over since I worked on this, but it should be very
close.  The only differnce I see on this config is that CONFIG_SLAB_DEBUG is
turned on.  Everything else should be identical

Thanks for the data. Your config could not apply on my kernel (net-next-2.6 master branch). So I attached the one I used for testing in case you see anything that is different. I made sure DEBUG_SLAB is enabled.

Is this the connectathon suite you were talking about:
http://www.connectathon.org/nfstests.html

I ran overnight stress (1000 iterations of the suite)  plus some netperf stress and so far no signs of issues on a z-200 platform. 

BTW the HP z-200 is still in pre-production stage. Looking at the eeprom you provided it seems older than what we have. You should probably look into getting an updated FW.

Thanks,
Emil

It might not apply cleanly no.  as I said, I had to reconstruct it (it was

That might be worth looking into.  Thanks.  That said however, if its possible
for the eeprom to allow overlength frames to get dma-ed, isn't it worthwhile to
ensure that our allocation size matches what we tell the driver it is?  We
already do so in e1000_change_mtu:
...

	if (max_frame <= 256)
                adapter->rx_buffer_len = 256;
        else if (max_frame <= 512)
                adapter->rx_buffer_len = 512;
        else if (max_frame <= 1024)
                adapter->rx_buffer_len = 1024;
        else if (max_frame <= 2048)
                adapter->rx_buffer_len = 2048;
        else
                adapter->rx_buffer_len = 4096;
...

These patches just ensure that the same normalization is done for the initial
size of rx_buffer_len, should userspace never change the mtu of the NIC.

I have a memory dump from an SLE10 SP3 machine that seems to reproduce
this issue. The testing environment was netperf with the MTU being
switched every minute from 9000 -> 1500 and it took 40 hours to hit
the bug. So, an overnight test, as you tried, may not be enough.

In the memory dump there are 6 skb's in the ring that have memory
overwritten from skb->data to skb->data + 2048. The machine ended up
oopsing in skb_release_data() from e1000_clean_all_rx_rings() from
e1000_change_mtu().

I will let you know if this patch ended up helping.

Cheers,

Thanks for testing Brandon, I think your test (with e1000e 1.0.2.5) is 
significantly different than the test that Neil started with.  That said I 
think it is a valuable test and we are going to start a test today that 
uses pktgen on two machines to send 64 byte and 9014 byte packets to a 
host that is changing its MTU every 5-10 seconds.

I think we should put a patch like the below into the kernel and actually 
*catch* any overrun DMAs even on a production machine.  At that point we 
could even leak that skb memory to prevent the corrupted memory from 
making its way into the general environment.

what kind of system is this that had such a high bus number? PPC64?

e1000_change_mtu could possibly have a race that would allow corruption if 
all receives were not completed in the time we waited (10 millseconds) for 
some reason, but only if LPE was cleared already.  I still think your test 
is significantly different and maybe showing a different (but similar) 
edge case bug than Neil.

shouldn't IOMMU systems be catching this too when it was occuring?  we 
only call pci_map_* with buffer_info->length which is assigned 
rx_buffer_len.

e1000/e1000e: check rx length for overruns

From: Jesse Brandeburg <jesse.brandeburg@intel.com>

it has been reported that some tests can cause DMA overruns resulting in
corrupted memory.  If the hardware writes more data to memory than we had
allocated this is something we can check for.

For now, WARN_ON, with the future capability of doing something like leaking
the memory rather than returning a known corrupt buffer to userspace.

I think this seems like a reasonable idea.  Additionally (or perhaps
alternatively), it might be a good idea to (when allocating buffers in the
default setup path), expand the allocation size by a word, that we write a
cannary value into.  Then we can check that cannary on the napi poll should the
hardware dma past the end of the skb.
