* sctp: Adjust PMTU updates to accomodate route invalidation.David S. Miller2012-07-167-14/+22
| | | | | | | | | This adjusts the call to dst_ops->update_pmtu() so that we can transparently handle the fact that, in the future, the dst itself can be invalidated by the PMTU update (when we have non-host routes cached in sockets). Signed-off-by: David S. Miller <davem@davemloft.net>
* ipv6: Add helper inet6_csk_update_pmtu().David S. Miller2012-07-164-78/+45Star

* ipv4: Add helper inet_csk_update_pmtu().David S. Miller2012-07-164-18/+52
| | | | | | | | | | | | | | | This abstracts away the call to dst_ops->update_pmtu() so that we can transparently handle the fact that, in the future, the dst itself can be invalidated by the PMTU update (when we have non-host routes cached in sockets). So we try to rebuild the socket cached route after the method invocation if necessary. This isn't used by SCTP because it needs to cache dsts per-transport, and thus will need it's own local version of this helper. Signed-off-by: David S. Miller <davem@davemloft.net>
* xfrm: Initialize the struct xfrm_dst behind the dst_enty fieldSteffen Klassert2012-07-141-2/+3
| | | | | | | | | | | We start initializing the struct xfrm_dst at the first field behind the struct dst_enty. This is error prone because it might leave a new field uninitialized. So start initializing the struct xfrm_dst right behind the dst_entry.

The bcma bus got a lot of attention from Hauke Mehrtens. The cfg80211 component gets a flurry of patches for multi-channel support, and the mac80211 component gets the first few VHT (11ac) and 60GHz (11ad) patches. This also includes the removal of the iwmc3200 drivers, since the hardware never became available to normal people. Additionally, the NFC subsystem gets a series of updates. According to Samuel, "Here are the interesting bits: - A better error management for the HCI stack. - An LLCP "late" binding implementation for a better NFC SAP usage. SAPs are now reserved only when there's a client for it. - Support for Sony RC-S360 (a.k.a. PaSoRi) pn533 based dongle. We can read and write NFC tags and also establish a p2p link with this dongle now. - A few LLCP fixes." Finally, this includes another pull of the fixes from the wireless tree in order to resolve some merge issues. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

In the original submission to staging PCIE() checked, if the bustype is PCI and the buscore is a PCIe core. Now we assume that all cores bcma supports are PCIe based, so we just have to check if the bustype is PCI. The old code bcmsmac currently uses searches for a PCIe core on the bus and if there is one assumes that this is the buscore, which is wrong. Some SoCs have a PCIe core operating in host mode and this is not the bus core. The old code also caused a null pointer in ai_get_buscoretype() and ai_get_buscorerev() if buscore was not set because there was no PCIe core on the bus.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | wlcore needs to wait for certain events for example for roc complete event. Usually the events are received from the FW very fast, therefore wlcore can poll with a short delay and if after a second the event was not received yet poll with a long (1-5 msec) delay. This implementation is similar to the sending of commands to the FW. Empirically the change reduced the wait for roc event from ~10-40msec to 100s of usecs.

| | * wlcore: Prevent processing of work items during op_stopIdo Yariv2012-07-103-25/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The interrupt line is disabled in op_stop using disable_irq. Since pending interrupts are synchronized, the mutex has to be released before disabling the interrupt to avoid a deadlock with the interrupt handler. In addition, the internal state of the driver is only set to 'off' after the interrupt is disabled. Otherwise, if an interrupt fires after the state is set but before the interrupt line is disabled, the interrupt handler will not be able to acknowledge the interrupt resulting in an interrupt storm. The driver's operations might be called during recovery. If these acquire the mutex after it was released by op_stop, but before the driver's state is changed, they may queue new work items instead of just failing. This is especially problematic in the case of scans, in which a new scan may be scheduled after all scan requests were cancelled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have some API changes and new features in the new firmwares that are not compatible with older drivers. Increase the version of the FW filenames for wl12xx to 5. Additionally, remove the duplicate definitions from wlcore_i.h and remove the MODULE_FIRMWARE macro calls from the SDIO and SPI modules, since they're irrelevant there.

| | * wlcore: add probe request templates for sched and one-shot scansYoni Divinsky2012-07-106-9/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver configures the firmware template for probe requests during the scan process. If the same template is used for one-shot and sched scans they will override each other when running scans simultaneously. This fix works only on firmwares later than X.3.9.2.112 for single role and X.3.9.2.23 for multi-role.
