2010-09-24e1000: fix occasional panic on unloadJesse Brandeburg1-1/+19
Net drivers in general have an issue where timers fired by mod_timer or work threads with schedule_work are running outside of the rtnl_lock. With no other lock protection these routines are vulnerable to races with driver unload or reset paths. The longer term solution to this might be a redesign with safer locks being taken in the driver to guarantee no reentrance, but for now a safe and effective fix is to take the rtnl_lock in these routines.

2010-09-23e1000/e1000e/igb/ixgb/ixgbe: set NETIF_F_HIGHDMA for VLAN feature flagsYi Zou1-1/+3
If the netdev->features is set with NETIF_F_HIGHDMA, we should set the corresponding netdev->vlan_features as well to allow VLAN netdev created on top of the real netdev to be able to also benefit from HIGHDMA on 32bit system, reducing the performance hit that is caused by __skb_linearize(), particularly for large send. This is fixed in this patch for all Intel e1000, e1000e, igb, ixgbe, and ixgbe drivers since this should be beneficial to all devices supported by these drivers.

2010-09-09e1000: fix Tx hangs by disabling 64-bit DMAJesse Brandeburg1-70/+92
Several users report issues with 32-bit adapters when plugged into PCI slots in machines with >= 4GB ram. In particular AMD systems with HyperTransport to PCI bridges seem to trigger the issue, but it isn't limited to only them. This issue is not easily reproducible here, yet still continues to occur in the field. For e1000 on PCI devices, just disable DMA addresses over the 4GB boundary when in PCI (not PCI-X) mode, to prevent the issue from continuing to pop up. The performance impact for this is negligible. The code was refactored to move the init of the hw struct to its own function. This allows the init to be called very early in probe, which then allows using hw-> members for this fix. A slight refactor to the DMA mask code was done for minor correctness based on the instructions in DMA-API-HOWTO.

2010-08-09e100/e1000*/igb*/ixgb*: Add missing read memory barrierJeff Kirsher1-0/+3
Based on patches from Sonny Rao and Milton Miller... Combined the patches to fix up clean_tx_irq and clean_rx_irq. The PowerPC architecture does not require loads to independent bytes to be ordered without adding an explicit barrier. In ixgbe_clean_rx_irq we load the status bit then load the packet data. With packet split disabled if these loads go out of order we get a stale packet, but we will notice the bad sequence numbers and drop it. The problem occurs with packet split enabled where the TCP/IP header and data are in different descriptors. If the reads go out of order we may have data that doesn't match the TCP/IP header. Since we use hardware checksumming this bad data is never verified and it makes it all the way to the application. This bug was found during stress testing and adding this barrier has been shown to fix it. The bug can manifest as a data integrity issue (bad payload data) or as a BUG in skb_pull(). This was a nasty bug to hunt down, if people agree with the fix I think it's a candidate for stable. Previously Submitted to e1000-devel only for ixgbe http://marc.info/?l=e1000-devel&m=126593062701537&w=3 We've now seen this problem hit with other device drivers (e1000e mostly) So I'm resubmitting with fixes for other Intel Device Drivers with similar issues.

2010-01-23e1000/e1000e: don't use small hardware rx buffersJesse Brandeburg1-19/+1
When testing the "e1000: enhance frame fragment detection" (and e1000e) patches we found some bugs with reducing the MTU size. The 1024 byte descriptor used with the 1000 mtu test also (re) introduced the (originally) reported bug, and causes us to need the e1000_clean_tx_irq "enhance frame fragment detection" fix. So what has occured here is that 2.6.32 is only vulnerable for mtu < 1500 due to the jumbo specific routines in both e1000 and e1000e. So, 2.6.32 needs the 2kB buffer len fix for those smaller MTUs, but is not vulnerable to the original issue reported. It has been pointed out that this vulnerability needs to be patched in older kernels that don't have the e1000 jumbo routine. Without the jumbo routines, we need the "enhance frame fragment detection" fix the e1000, old e1000e is only vulnerable for < 1500 mtu, and needs a similar fix. We split the patches up to provide easy backport paths. There is only a slight bit of extra code when this fix and the original "enhance frame fragment detection" fixes are applied, so please apply both, even though it is a bit of overkill.

2010-01-21e1000: enhance frame fragment detectionJesse Brandeburg2-2/+13
Originally From: Neil Horman <nhorman@tuxdriver.com> Modified by: Jesse Brandeburg <jesse.brandeburg@intel.com> Hey all- A security discussion was recently given: http://events.ccc.de/congress/2009/Fahrplan//events/3596.en.html And a patch that I submitted awhile back was brought up. Apparently some of their testing revealed that they were able to force a buffer fragment in e1000 in which the trailing fragment was greater than 4 bytes. As a result the fragment check I introduced failed to detect the fragement and a partial invalid frame was passed up into the network stack. I've written this patch to correct it. I'm in the process of testing it now, but it makes good logical sense to me. Effectively it maintains a per-adapter state variable which detects a non-EOP frame, and discards it and subsequent non-EOP frames leading up to _and_ _including_ the next positive-EOP frame (as it is by definition the last fragment). This should prevent any and all partial frames from entering the network stack from e1000.

2009-09-27e1000: two workarounds were incomplete, fix themJesse Brandeburg1-7/+10
1) 82544 does not need last_tx_tso workaround, it interferes with the 82544 workaround too 2) 82544 hang workaround was using the address of the page struct instead of the physical address as its "workaround decider" not sure how that ever worked Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Signed-off-by: Don Skidmore <donald.c.skidmore@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S.
