| * batman-adv: skip the window protection test when the originator has no ↵Antonio Quartulli2012-04-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | neighbours When we receive an OGM from from a node for the first time, the last_real_seqno field of the orig_node structure has not been initialised yet. The value of this field is used to compute the current ogm-seqno window and therefore the protection mechanism will probably drop the packet due to an out-of-window error. To avoid this situation this patch adds a check to skip the window protection mechanism if no neighbour nodes have already been added. When the first neighbour node is added, the last_real_seqno field is initialised too. Reported-by: Marek Lindner <lindner_marek@yahoo.de> Signed-off-by: Antonio Quartulli <ordex@autistici.org>

| * net/ethernet: ks8851_mll fix rx frame buffer overflowDavide Ciminaghi2012-04-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At the beginning of ks_rcv(), a for loop retrieves the header information relevant to all the frames stored in the mac's internal buffers. The number of pending frames is stored as an 8 bits field in KS_RXFCTR. If interrupts are disabled long enough to allow for more than 32 frames to accumulate in the MAC's internal buffers, a buffer overflow occurs. This patch fixes the problem by making the driver's frame_head_info buffer big enough. Well actually, since the chip appears to have 12K of internal rx buffers and the shortest ethernet frame should be 64 bytes long, maybe the limit could be set to 12*1024/64 = 192 frames, but 255 should be safer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A workaround was previously put in the driver to reset the device when transitioning to Sx in order to activate the changed settings of the PHY OEM bits (Low Power Link Up, or LPLU, and GbE disable configuration) for 82577/8/9 devices. After further review, it was found such a reset can cause the 82579 to confuse which version of 82579 it actually is and broke LPLU on all 82577/8/9 devices. The workaround during an S0->Sx transition on 82579 (instead of resetting the PHY) is to restart auto-negotiation after the OEM bits are configured; the restart of auto-negotiation activates the new OEM bits as does the reset. With 82577/8, the reset is changed to a generic reset which fixes the LPLU bits getting set wrong.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit e675f0cc9a872fd152edc0c77acfed19bf28b81e ("ppp: Don't stop and restart queue on every TX packet") introduced a race condition which could leave the net queue stopped even when the channel is no longer busy. By calling netif_stop_queue() from ppp_start_xmit(), based on the return value from ppp_xmit_process() but *after* all the locks have been dropped, we could potentially do so *after* the channel has actually finished transmitting and attempted to re-wake the queue. Fix this by moving the netif_stop_queue() into ppp_xmit_process() under the xmit lock. I hadn't done this previously, because it gets called from other places than ppp_start_xmit(). But I now think it's the better option. The net queue *should* be stopped if the channel becomes congested due to writes from pppd, anyway.

* | macvlan: add FDB bridge ops and macvlan flagsJohn Fastabend2012-04-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds FDB bridge ops to the macvlan device passthru mode. Additionally a flags field was added and a NOPROMISC bit to allow users to use passthru mode without the driver calling dev_set_promiscuity(). The flags field is a u16 placed in a 4 byte hole (consuming 2 bytes) of the macvlan_dev struct. We want to do this so that the macvlan driver or stack above the macvlan driver does not have to process every packet. For the use case where we know all the MAC addresses of the endstations above us this works well. This patch is a result of Roopa Prabhu's work. Follow up patches are needed for VEPA and VEB macvlan modes. v2: Change from distinct nopromisc mode to a flags field to configure this. This avoids the tendency to add a new mode every time we need some slightly different behavior. v3: fix error in dev_set_promiscuity and add change and get link attributes for flags.

* | ixgbe: UTA table incorrectly programmedGreg Rose2012-04-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The UTA table was being set to the functional equivalent of promiscuous mode. This was resulting in traffic from the virtual function being flooded onto the wire and the PF device. This resulted in additional overhead for VF traffic sent to the network and in the case of traffic sent to the PF or another VF resulted in unwanted packets on the wire. This was actually not the intended behavior. Now that we can program the embedded switch correctly we can remove this snippit of code. Users who want to support this should configure the FDB correctly using the FDB ops.
