Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-07-24 This series contains updates to igb, ixgbe, i40e and i40evf. Mark fixes a possible attempt to dereference a NULL pointer in ixgbe_probe(). Also changes some uses of strncpy to strlcpy when clearing is not needed to prevent information leakage. Jacob fixes a bug in the misuse of the list_for_each macro to loop over every entry in the bus_list. Instead of attempting to loop over the list from a random entry point, go up to the bus and use the real list_head entry point. This prevents the possible read or write of unallocated or incorrectly addressed memory. Then provides a patch to prevent the display of the minimum link qualification check if we might be in a virtual machine. This check is incorrect and misleading in this case, since we actually do not really know what the available bandwidth is. To do so, we simply check whether each function on the bus matches our device id. Carolyn adds a check and prints the error cause register value when the hardware detects a malformed packet to assist the user. Toralf Förster fixes a format mismatch in i40e which was found using cppcheck. Shannon adds nvmupdate support by implementing a state machine intended to support the userland tool for updating the device eeprom. Jesse fixes the extension header checksum logic for IPv6 in i40e and i40evf. Mitch reduces a delay in the i40evf driver where we do not need to delay an entire millisecond to get into our critical section. Kamil fixes an issue where access to the NVM was being blocked until a driver reset where a check for NVM related admin queue commands would not recognize that such a command was received and would not clear nvm_busy flag. Catherine fixes a couple of firmware API version errors. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

由 Simon Horman 提交于
The sample action is rather generic, allowing arbitrary actions to be executed based on a probability. However its use, within the Open vSwitch code-base is limited: only a single user-space action is ever nested. A consequence of the current implementation of sample actions is that depending on weather the sample action executed (due to its probability) any side-effects of nested actions may or may not be present before executing subsequent actions. This has the potential to complicate verification of valid actions by the (kernel) datapath. And indeed adding support for push and pop MPLS actions inside sample actions is one case where such case. In order to allow all supported actions to be continue to be nested inside sample actions without the potential need for complex verification code this patch changes the implementation of the sample action in the kernel datapath so that sample actions are more like a function call and any side effects of nested actions are not present when executing subsequent actions. With the above in mind the motivation for this change is twofold: * To contain side-effects the sample action in the hope of making it easier to deal with in the future and; * To avoid some rather complex verification code introduced in the MPLS datapath patch.

Give link a little more time to come back up after setting flow control before resetting. In the new NVMs it is taking longer for link to come back. This causes the driver to attempt to reset the link, which then errors because the firmware was already in the middle of a reset. Also, initialize err to 0.

Copy desc and buffer data even for ARQ events which return error status. Previously, a check for NVM related AQ commands which is done later in this function would not recognize that such a command was received and would not clear nvm_busy flag. This would block access to NVM until a driver reset. This will fix that.

The hardware design requires that the driver avoid indicating checksum offload success on some ipv6 frames with extension headers. The code needs to just check for the IPV6EXADD bit and if it is set punt the checksum to the stack. I don't know why the code was checking TCP on inner protocol, as that code doesn't make any sense to me but seems wrong, so remove it.

This implements a state machine intended to support the userland tool for updating the device eeprom. The state machine implements one-shot reads, writes, multi-step write sessions, and checksum requests. If we're in the middle of a multi-step write session, no one should fire off other writes, however, one shot reads are valid. The userland tool is expected to keep track of its session status, arrange the placement and ordering of the writes, and deal with the checksum requirement. This patch also adds nvmupdate support to ethtool callbacks. The get_eeprom() and set_eeprom() services in ethtool are used here to facilitate the userland NVMUpdate tool. The 'magic' value in the get and set commands is used to pass additional control information for managing the read and write steps. The read operation works both as normally expected in the standard ethtool method, as well as with the extra NVM controls. The write operation works only for the expanded NVM functions - the normal ethtool method is not allowed because of the NVM semaphore management needed for multipart writes, as well as the checksum requirement.
