2014-05-30af_iucv: correct cleanup if listen backlog is fullUrsula Braun
In case of transport HIPER a sock struct is allocated for an incoming connect request. If the backlog queue is full this socket is not needed, but is left in the list of af_iucv sockets. Final socket release posts console message "Attempt to release alive iucv socket". This patch makes sure the new created socket is cleaned up correctly if the backlog queue is full.

2014-05-30be2net: cleanup MCC async event processing codeSathya Perla
The MCC async event processing code has 2 issues: a) because of long struct names the code indentation is badly broken b) description and definitions of how an MCC completion is interpreted as an async event are confusing (for e.g. the last word of an MCC event is named "code", while "code" is just a sub-field of the last word.) This patch fixes the structure definitions, comments and re-factors code as needed. Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-05-30be2net: move async cmd processing to a separate routineSathya Perla
For some FW cmds, the caller just issues the cmd and doesn't wait for a response. The response handling is done in the MCCQ compl processing context only.

2014-05-30be2net: re-factor MCCQ error status handling codeKalesh AP
This patch improves MCCQ error status handling in the following ways: a) A MCC cmd completion returns a base-status and an addl-status. So far, the routine be_mcc_compl_process() returned only the "status" value. Now, embedd both statuses in the return value and let the caller routine access the value of interest using base_status() and addl_status() macros. b) Rename variables accordingly (base/addl) to avoid confusion while error checking. b) Some of the errors returned by FW are harmless and so an error msg is not logged for such errors. Capture this logic in a separate routine to make the code more readable.

Legacy platform data support is obviously kept intact. - NFC Tag type 4B support to the NFC Digital stack. - SOCK_RAW type support to the raw NFC socket, and allow NCI sniffing from that. This can be extended to report HCI frames and also proprietarry ones like e.g. the pn533 ones."

Renames ixgbe_ptp_enable() to ixgbe_ptp_feature_enable() to better reflect the functions purpose. Extracts the hardware setup logic for the PTP hardware bits from the ixgbe_ptp_set_ts_config() to enable future work for the ixgbe_ptp_reset(). Maintain the hwstamp configuration through a reset and extracts the creation of the PTP clock device from ptp_init() in order to properly handle a suspend/resume cycle and only calls it if we don't already have a ptp_clock pointer.

2014-05-26e1000e: Failure to write SHRA turns on PROMISC modeDavid Ertman
Previously, the check to turn on promiscuous mode only took into account the total number of SHared Receive Address (SHRA) registers and if the request was for a register within that range. It is possible that the Management Engine might have locked a number of SHRA and not allowed a new address to be written to the requested register. Add a function to determine the number of unlocked SHRA registers. Then determine if the number of registers available is sufficient for our needs, if not then return -ENOMEM so that UNICAST PROMISC mode is activated. Since the method by which ME claims SHRA registers is non-deterministic, also add a return value to the function attempting to write an address to a SHRA, and return a -E1000_ERR_CONFIG if the write fails. The error will be passed up the function chain and allow the driver to also set UNICAST PROMISC when this happens.

2014-05-26ixgbe: avoid duplicate code in suspend and stop pathsJacob Keller
Resume path calls .open but suspend path cannot call .stop because fdirs should not be freed and control over hardware should not be released until WoL is configured. To avoid having to duplicate all changes made in .stop on suspend path split out part of .stop that is relevant during suspend and call it from .stop and during suspend. This fix also ensures that ixgbe_ptp_suspend is called during the suspend path, and helps avoid similar errors. We can't call ixgbe_ptp_stop, since it will free the PTP clock device, which we shouldn't be doing during a suspend path.

2014-05-26ixgbe: separate the PTP suspend and stop actionsJacob Keller
Since we are adding proper support for suspend of PTP, extract out of ixgbe_ptp_stop those things relevant to suspend. Then, have ixgbe_ptp_stop call ixgbe_ptp_suspend. The next patch in the series will have ixgbe_ptp_suspend called from the ixgbe_suspend path.

2014-05-26ixgbe: extract PTP clock device from ptp_initJacob Keller
In order to properly handle a suspend/resume cycle, we cannot destroy the PTP clock device. As part of this, we should only re-create the device on first initialization. After a resume, when ixgbe_ptp_init is called, we won't create a new clock, and we will use the old clock device. To that end, this patch extracts the clock creation out of ptp_init, and only calls it if we don't already have a ptp_clock pointer.

2014-05-26ixgbe: allow ixgbe_ptp_reset to maintain current hwtstamp configJacob Keller
Rather than clearing the hwtstamp configuration, we should use the known configuration requested by the user and call the function which has now been separated from the ioctl. This means that after a reset, the timestamp mode will be maintained rather than lost. We still can't maintain the clock value, however.

2014-05-26ixgbe: extract the hardware setup from the ixgbe_ptp_set_ts_configJacob Keller
Currently all of the hardware setup logic for the PTP hardware bits is buried inside of the ioctl which sets the timestamp configuration. This makes it hard to use this logic in other places (primarily reset), and this means we can't restore current timestamp mode upon a MAC reset. Extracting this logic into a separate function will enable future work for the ixgbe_ptp_reset function.

2014-05-26ixgbe: rename ixgbe_ptp_enable to ixgbe_ptp_feature_enableJacob Keller
Since the name ixgbe_ptp_enable could be misconstrued as a function which enables the whole PTP core, rename this function so that it is clear the function is for enabling of the extra features such as PPS signal.
