2010-02-26can: netlink support for bus-error reporting and countersWolfgang Grandegger
This patch makes the bus-error reporting configurable and allows to retrieve the CAN TX and RX bus error counters via netlink interface. I have added support for the SJA1000. The TX and RX bus error counters are also copied to the data fields 6..7 of error messages when state changes are reported.

2010-02-23net: bug fix for vlan + gro issueAjit Khaparde
Traffic (tcp) doesnot start on a vlan interface when gro is enabled. Even the tcp handshake was not taking place. This is because, the eth_type_trans call before the netif_receive_skb in napi_gro_finish() resets the skb->dev to napi->dev from the previously set vlan netdev interface. This causes the ip_route_input to drop the incoming packet considering it as a packet coming from a martian source. I could repro this on 2.6.32.7 (stable) and 2.6.33-rc7. With this fix, the traffic starts and the test runs fine on both vlan and non-vlan interfaces.

e->index overflows e->stamps[] every ip_pkt_list_tot packets. Consider the case when ip_pkt_list_tot==1; the first packet received is stored in e->stamps[0] and e->index is initialized to 1. The next received packet timestamp is then stored at e->stamps[1] in recent_entry_update(), a buffer overflow because the maximum e->stamps[] index is 0.

2010-02-23tc35815: Remove a wrong netif_wake_queue() call which triggers BUG_ONAtsushi Nemoto
The netif_wake_queue() is called correctly (i.e. only on !txfull condition) from txdone routine. So Unconditional call to the netif_wake_queue() here is wrong. This might cause calling of start_xmit routine on txfull state and trigger BUG_ON. This bug does not happen when NAPI disabled. After txdone there must be at least one free tx slot. But with NAPI, this is not true anymore and the BUG_ON can hits on heavy load. In this driver NAPI was enabled on 2.6.33-rc1 so this is regression from 2.6.32 kernel.

2010-02-22ixgbe: prevent speculative processing of descriptors before readyMilton Miller
The PowerPC architecture does not require loads to independent bytes to be ordered without adding an explicit barrier. In ixgbe_clean_rx_irq we load the status bit then load the packet data. With packet split disabled if these loads go out of order we get a stale packet, but we will notice the bad sequence numbers and drop it. The problem occurs with packet split enabled where the TCP/IP header and data are in different descriptors. If the reads go out of order we may have data that doesn't match the TCP/IP header. Since we use hardware checksumming this bad data is never verified and it makes it all the way to the application. This bug was found during stress testing and adding this barrier has been shown to fix it.
