2014-04-14dma: edma: fix incorrect SG list handlingSekhar Nori
The code to handle any length SG lists calls edma_resume() even before edma_start() is called. This is incorrect because edma_resume() enables edma events on the channel after which CPU (in edma_start) cannot clear posted events by writing to ECR (per the EDMA user's guide). Because of this EDMA transfers fail to start if due to some reason there is a pending EDMA event registered even before EDMA transfers are started. This can happen if an EDMA event is a byproduct of device initialization. Fix this by calling edma_resume() only if it is not the first batch of MAX_NR_SG elements. Without this patch, MMC/SD fails to function on DA850 EVM with DMA. The behaviour is triggered by specific IP and this can explain why the issue was not reported before (example with MMC/SD on AM335x). Tested on DA850 EVM and AM335x EVM-SK using MMC/SD card.

2014-04-13filter: prevent nla extensions to peek beyond the end of the messageMathias Krause
The BPF_S_ANC_NLATTR and BPF_S_ANC_NLATTR_NEST extensions fail to check for a minimal message length before testing the supplied offset to be within the bounds of the message. This allows the subtraction of the nla header to underflow and therefore -- as the data type is unsigned -- allowing far to big offset and length values for the search of the netlink attribute. The remainder calculation for the BPF_S_ANC_NLATTR_NEST extension is also wrong. It has the minuend and subtrahend mixed up, therefore calculates a huge length value, allowing to overrun the end of the message while looking for the netlink attribute. The following three BPF snippets will trigger the bugs when attached to a UNIX datagram socket and parsing a message with length 1, 2 or 3. ,-[ PoC for missing size check in BPF_S_ANC_NLATTR ]-- | ld #0x87654321 | ldx #42 | ld #nla | ret a `--- ,-[ PoC for the same bug in BPF_S_ANC_NLATTR_NEST ]-- | ld #0x87654321 | ldx #42 | ld #nlan | ret a `--- ,-[ PoC for wrong remainder calculation in BPF_S_ANC_NLATTR_NEST ]-- | ; (needs a fake netlink header at offset 0) | ld #0 | ldx #42 | ld #nlan | ret a `--- Fix the first issue by ensuring the message length fulfills the minimal size constrains of a nla header. Fix the second bug by getting the math for the remainder calculation right.

2014-04-13Revert "net: mvneta: fix usage as a module on RGMII configurations"Thomas Petazzoni
This reverts commit e3a8786c10e75903f1269474e21fe8cb49c3a670. While this commit allows to use the mvneta driver as a module on some configurations, it breaks other configurations even if mvneta is used built-in. This breakage is due to the fact that on some RGMII platforms, the PCS bit has to be set, and on some other platforms, it has to be cleared. At the moment, we lack informations to know exactly the significance of this bit (the datasheet only says "enables PCS"), and so we can't produce a patch that will work on all platforms at this point. And since this change is breaking the network completely for many users, it's much better to revert it for now. We'll come back later with a proper fix that takes into account all platforms. Basically: * Armada XP GP is configured as RGMII-ID, and needs the PCS bit to be set. * Armada 370 Mirabox is configured as RGMII-ID, and needs the PCS bit to be cleared. And at the moment, we don't know how to make the distinction between those two cases. One hint is that the Armada XP GP appears in fact to be using a QSGMII connection with the PHY (Quad-SGMII), but configuring it as SGMII doesn't work, while RGMII-ID works. This needs more investigation, but in the mean time, let's unbreak the network for all those users.

2014-04-13net/mlx4_core: Preserve pci_dev_data after __mlx4_remove_one()Wei Yang
pci_match_id() just match the static pci_device_id, which may return NULL if someone binds the driver to a device manually using /sys/bus/pci/drivers/.../new_id. This patch wrap up a helper function __mlx4_remove_one() which does the tear down function but preserve the drv_data. Functions like mlx4_pci_err_detected() and mlx4_restart_one() will call this one with out releasing drvdata.
