2014-03-28i40e: eeprom integrity check on load and emprShannon Nelson
The driver needs to verify the eeprom checksum and firmware crc status bits, and shutdown the driver if they fail. This code stops the processing of traffic, but doesn't kill the PF netdev so that the NVMUpdate process should still have a chance at fixing the image. The eeprom is checked on driver load and after an EMP reset, the latter of which should be generated after an NVMUpdate.

2014-03-28i40e: Make the alloc and free queue vector calls orthogonalGreg Rose
It's annoying to search for a matching alloc and free set of function calls when they don't use the same framework for the name of the functions. Fix that up in the case of alloc and free of vsi queue vectors. i40e_vsi_free_q* i40e_vsi_alloc_q* Change-ID: I510eb863a0fbe405312bebea55c2846c76285e6d Signed-off-by: Greg Rose <gregory.v.rose@intel.com> Signed-off-by: Catherine Sullivan <catherine.sullivan@intel.com> Tested-by: Kavindya Deegala <kavindya.s.deegala@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
2014-03-28i40evf: fix oops in watchdog handlerMitch Williams
The Tx watchdog handler runs in interrupt context, so it would cause an oops when sending an admin queue message to request a reset, because the admin queue functions use spinlocks. Instead, set a flag and let the reset task handle sending the request.

regmap: Fix for v3.14 One fix here, for syncing the last register in a cache block when the register map has a stride. This is a fairly unusual hardware configuration and the fact that it only affects the last register in a block makes the issue rarer still. # gpg: Signature made Sun 23 Feb 2014 04:36:37 GMT using RSA key ID 7EA229BD # gpg: Good signature from "Mark Brown <broonie@sirena.org.uk>" # gpg: aka "Mark Brown <broonie@debian.org>" # gpg: aka "Mark Brown <broonie@kernel.org>" # gpg: aka "Mark Brown <broonie@tardis.ed.ac.uk>" # gpg: aka "Mark Brown <broonie@linaro.org>" # gpg: aka "Mark Brown <Mark.Brown@linaro.org>"

2014-03-27net: bcmgenet: set RBUF_SKIP_FCS based on UniMAC CRC forwardingFlorian Fainelli
When the UniMAC block is configured to forward the CRC as part of the Ethernet frame (priv->crc_fwd_en, set by default), enabling the hardware RX checksum block unveiled that the dma_rxchk_bit was never set in the per-packet status bits (dma_flag in bcmgenet_desc_rx). This would make the chksum_ok variable to be never set to 1, and the networking stack would have to compute the packet checksums, which takes a substantial amount of time. In order for the RXCHK block to properly compute the packet checksum in hardware, we also need to set the RBUF_SKIP_FCS bit accordingly.

2014-03-27usbnet: include wait queue head in device structureOliver Neukum
This fixes a race which happens by freeing an object on the stack. Quoting Julius: > The issue is > that it calls usbnet_terminate_urbs() before that, which temporarily > installs a waitqueue in dev->wait in order to be able to wait on the > tasklet to run and finish up some queues. The waiting itself looks > okay, but the access to 'dev->wait' is totally unprotected and can > race arbitrarily. I think in this case usbnet_bh() managed to succeed > it's dev->wait check just before usbnet_terminate_urbs() sets it back > to NULL. The latter then finishes and the waitqueue_t structure on its > stack gets overwritten by other functions halfway through the > wake_up() call in usbnet_bh(). The fix is to just not allocate the data structure on the stack. As dev->wait is abused as a flag it also takes a runtime PM change to fix this bug.
