| | | * mlx4_core: Allow choosing flow steering modeJack Morgenstein2012-12-193-16/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Device managed flow steering will be enabled only under administrator directive provided through setting the existing module parameter log_num_mgm_entry_size to -1 (if the device actually supports flow steering). If flow steering isn't requested or not available, the driver will use the value of log_num_mgm_entry_size and B0 steering.

| | | * mlx4_core: Adjustments to Flow Steering activation logic for SR-IOVJack Morgenstein2012-12-193-25/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Separate flow steering capability detection from the decision to activate. For the master (and for native), detect the flow steering capability in mlx4_dev_cap, but activate the appropriate steering type in a new function choose_flow_steering() based on detected data. For VFs, activate flow steering based on what was actually activated by the master, where that info is obtained via QUERY_HCA. This fixes the current VF detection which is wrongly based on QUERY_DEV_CAP. Also, for SR-IOV mode, if flow steering may be activated, do so only if the max number of QPs per rule is sufficient to satisfy one subscription per VF. If not, fall back to B0 mode. This is needed to serve registrations done by L2 network drivers such as mlx4_en and IPoIB when the network stack attempts to join to multicast groups such as all-hosts or the IPoIB broadcast group.

It divides filter region into regular filters and server filter portion. It introduces new server filter region which will be exclusively used for creating server filters. This region will not overlap with regular filter region. It provides new API cxgb4_alloc_sftid in LLD for getting stid in case of LE hash collision path.

| * | cxgb4: Add T4 filter supportVipul Pandya2012-12-198-7/+757
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | The T4 architecture is capable of filtering ingress packets at line rate using the rule in TCAM. If packet hits a rule in the TCAM then it can be either dropped or passed to the receive queues based on a rule settings. This patch adds framework for managing filters and to use T4's filter capabilities. It constructs a Firmware Filter Work Request which writes the filter at a specified index to get the work done. It hosts shadow copy of ingress filter entry to check field size limitations and save memory in the case where the filter table is large.

The implementation also penalizes fast path with extra memory accesses for the benefit of ring full condition handling which is slow path. It's easy to query ring capacity so let's do just that.

As a result of this, the ksz884x receive path ends up locking up fairly easily, when the receive processing tasklet's reenabling of receive interrupts (due to it being done with polling the receive ring) races with the interrupt handler's disabling of receive interrupts (due to a new receive interrupt coming in) resulting in the receive interrupt being masked but the receive processing tasklet not being scheduled. Fix this by making the ksz884x interrupt handler take its private interface spinlock. This requires upgrading the spin_lock() in the transmit cleanup tasklet to a spin_lock_irq(), as otherwise the IRQ handler can preempt transmit cleanup and deadlock the system, but with those two changes, no more receive lockups have been observed.

Before fec driver gets fixed to run-time detect target hardware rather than conditional compiling with #ifdef CONFIG_FEC_PTP, let's give it a quick fix in Kconfig to forbid FEC_PTP on those IMX SoCs that do not support PTP.

This hits a BUG_ON() in be2net. When completion coalescing is enabled on a CQ, an explicit CQ-notify (with rearm) is needed for each compl, to flush partially coalesced CQ entries that are pending DMA. In be_close(), this fix now notifies CQ for each compl, waits explicitly for the flush compl to arrive and complains if it doesn't arrive. Also renaming be_crit_error() to be_hw_error() as it's the more appropriate name and to convey that we don't wait for the flush compl only when a HW error has occurred.

But since the state of tuntap were completely removed from the queue, it could be used to attach to another device (there's no such kind of requirement currently, and it needs new kind of LSM policy. - TUNSETQUEUE could be used to attach to a persistent device without any queues. This kind of attching bypass the necessary checking during TUNSETIFF and may lead unexpected result. So this patch tries to make a cleaner and simpler API by: - Only allow TUNSETIFF to create queues. - TUNSETQUEUE could be only used to disable and enabled the queues of a device, and the state of the tuntap device were not detachd from the queues when it was disabled, so TUNSETQUEUE could be only used after TUNSETIFF and with the same device. This is done by introducing a list which keeps track of all queues which were disabled. The queue would be moved between this list and tfiles[] array when it was enabled/disabled. A pointer of the tun_struct were also introdued to track the device it belongs to when it was disabled. After the change, the isolation between management and application could be done through: TUNSETIFF were only called by management software and TUNSETQUEUE were only called by application.For LSM/SELinux, the things left is to do proper check during tun_set_queue() if needed.
