2010-08-19e1000e: don't check for alternate MAC addr on parts that don't support itBruce Allan3-13/+31
From: Bruce Allan <bruce.w.allan@intel.com> The alternate MAC address feature is only supported by 80003ES2LAN and 82571 LOMs as well as a couple 82571 mezzanine cards. Checking for an alternate MAC address on other parts can fail leading to the driver not able to load. This patch limits the check for an alternate MAC address to be done only for parts that support the feature. This issue has been around since support for the feature was introduced to the e1000e driver in 2.6.34.

2010-08-19e1000e: disable ASPM L1 on 82573Bruce Allan1-0/+1
On the e1000-devel mailing list, Nils Faerber reported latency issues with the 82573 LOM on a ThinkPad X60. It was found to be caused by ASPM L1; disabling it resolves the latency. The issue is present in kernels back to 2.6.34 and possibly 2.6.33.

2010-08-18ehea: Fix synchronization between HW and SW send queueAndre Detsch2-2/+61
ehea: Fix synchronization between HW and SW send queue When memory is added to / removed from a partition via the Memory DLPAR mechanism, the eHEA driver has to do a couple of things to reflect the memory change in its own IO address translation tables. This involves stopping and restarting the HW queues. During this operation, it is possible that HW and SW pointer into these queues get out of sync. This results in a situation where packets that are attached to a send queue are not transmitted immediately, but delayed until further X packets have been put on the queue. This patch detects such loss of synchronization, and resets the ehea port when needed.

2010-08-18netlink: fix compat recvmsgJohannes Berg1-30/+16
Since commit 1dacc76d0014a034b8aca14237c127d7c19d7726 Author: Johannes Berg <johannes@sipsolutions.net> Date: Wed Jul 1 11:26:02 2009 +0000 net/compat/wext: send different messages to compat tasks we had a race condition when setting and then restoring frag_list. Eric attempted to fix it, but the fix created even worse problems. However, the original motivation I had when I added the code that turned out to be racy is no longer clear to me, since we only copy up to skb->len to userspace, which doesn't include the frag_list length. As a result, not doing any frag_list clearing and restoring avoids the race condition, while not introducing any other problems. Additionally, while preparing this patch I found that since none of the remaining netlink code is really aware of the frag_list, we need to use the original skb's information for packet information and credentials. This fixes, for example, the group information received by compat tasks.

Remove validation of the per-connection sequence numbers on routable connections, since routable connections are not supported by TIPC.

2010-08-17tipc: Fix bug in broadcast link transmit statistics computationAllan Stephens1-3/+2
Modify TIPC's broadcast link so that it counts each piece of a fragmented message individually, rather than as treating the group as a single message. This ensures that proper correlation of sent and received traffic can be done when the broadcast link statistics are displayed, and is consistent with the way fragments are counted by TIPC's unicast links.

2010-08-17tipc: Fix premature broadcast advertisement by sending nodeAllan Stephens1-11/+19
Prevent a TIPC node from sending out a LINK_STATE message advertising a broadcast message that it is in the process of sending, but has not yet actually sent. Previously, it was possible for a link timeout to occur in between the time the broadcast link updated its "last message sent" counter and the time the broadcast message was passed to the broadcast bearer for transmission. This ensures that the code which issues the LINK_STATE message isn't informed of the new message until the broadcast bearer has had a chance to send it. Note: The "last message sent" value is stored in the "fsm_msg_count" field of the link structure used by the broadcast link. Since the broadcast link doesn't utilize the normal link FSM, this field can be re-used rather than adding a new field to the broadcast link.

2010-08-17tipc: Prevent crash when broadcast link cannot send to all nodesAllan Stephens1-4/+6
Allow TIPC's broadcast link to continue operation when it is unable to send a message to all nodes in the cluster. Previously, the broadcast link attempted to put the broadcast pseudo-bearer into a blocked state; however, this caused a crash because the associated bearer structure is only partially initialized. Further investigation has revealed some conceptual problems with blocking the pseudo-bearer; consequently, this functionality has been disabled for the time being and the undelivered message is eventually resent by the broadcast link's existing message retransmission mechanism (if possible).

2010-08-17tipc: Check for disabled bearer when processing incoming messagesAllan Stephens1-0/+14
Add a check to tipc_recv_msg() to ensure it discards messages arriving on a newly disabled bearer. This is needed to deal with a race condition that can arise if the bearer is in the midst of being disabled when it receives a message. Performing the check after tipc_net_lock has been taken ensures that TIPC's bearers are in a stable state while the message is being processed.
