* igb: Retain HW VLAN filtering while in promiscuous + VT modeGreg Rose2013-04-24
| | | | | | | | | | | | | | When using the new bridge FDB interface to allow SR-IOV virtual function network devices to communicate with SW bridged network devices the physical function is placed into promiscuous mode and hardware VLAN filtering is disabled. This defeats the ability to use VLAN tagging to isolate user networks. When the device is in promiscuous mode and VT mode simultaneously ensure that VLAN hardware filtering remains enabled.

The be2net driver had a bug fix in 'net' that overlapped with the VLAN interface changes by Patrick McHardy in net-next. An IGB conflict existed because in 'net' the build_skb() support was reverted, and in 'net-next' there was a comment style fix within that code. Several batman-adv conflicts were resolved by making sure that all calls to batadv_is_my_mac() are changed to have a new bat_priv first argument. Eric Dumazet's TS ECR fix in TCP in 'net' conflicted with the F-RTO rewrite in 'net-next', mostly overlapping changes.

| * igb: Revert support for build_skb in igbAlexander Duyck2013-04-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch actually reverts: igb: Support using build_skb in the case that jumbo frames are disabled The reason for reverting this patch is that it can lead to data corruption. The following flow was pointed out by Ben Hutchings: 1. skb is forwarded to another device 2. Packet headers are modified and it's put into a queue 3. Second packet is received into the other half of this page 4. Page cannot be reused, so is DMA-unmapped 5. The DMA mapping was non-coherent, so unmap copies or invalidates cache The headers added in step 2 get trashed in step 5.

* igb: fix PHC stopping on max freqJiri Benc2013-03-26
| | | | | | | | | | | | | | | | | For 82576 MAC type, max_adj is reported as 1000000000 ppb. However, if this value is passed to igb_ptp_adjfreq_82576, incvalue overflows out of INCVALUE_82576_MASK, resulting in setting of zero TIMINCA.incvalue, stopping the PHC (instead of going at twice the nominal speed). Fix the advertised max_adj value to the largest value hardware can handle. As there is no min_adj value available (-max_adj is used instead), this will also prevent stopping the clock intentionally. It's probably not a big deal, other igb MAC types don't support stopping the clock, either.

* igb: Fix null pointer dereferenceAlex Williamson2013-03-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The max_vfs= option has always been self limiting to the number of VFs supported by the device. fa44f2f1 added SR-IOV configuration via sysfs, but in the process broke this self correction factor. The failing path is: igb_probe igb_sw_init if (max_vfs > 7) { adapter->vfs_allocated_count = 7; ... igb_probe_vfs igb_enable_sriov(, max_vfs) if (num_vfs > 7) { err = -EPERM; ... This leaves vfs_allocated_count = 7 and vf_data = NULL, so we bomb out when igb_probe finally calls igb_reset. It seems like a really bad idea, and somewhat pointless, to set vfs_allocated_count separate from vf_data, but limiting max_vfs is enough to avoid the null pointer.

| | | | | | | | | | | | | | | | | | After reviewing the igb and ixgbe code I realized there are a few issues in how the code is structured. Specifically we are not checking the size of the buffers being used in transmits and we are not using the same value to determine when to stop or start a Tx queue. As such the code is prone to be buggy. This patch makes it so that we have one value DESC_NEEDED that we will use for starting and stopping the queue. In addition we will check the size of buffers being used when setting up a transmit so as to avoid a possible buffer overrun if we were to receive a frame with a block of data larger than 32K in skb->data.

* igb: Replace rmb in Tx cleanup with read_barrier_dependsAlexander Duyck2013-01-19
| | | | | | | | | | The rmb in the Tx cleanup path is a much stronger barrier than we really need. All that is really needed is a read_barrier_depends since the location of the EOP descriptor is dependent on the eop_desc value.

* igb: Free any held skb that should have been timestamped on removeMatthew Vick2013-01-18
| | | | | | | | | | | | To prevent a race condition where an skb has been saved to return the Tx timestamp later and the driver is removed, add a check to determine if we have an skb stored and, if so, free it.
