After 2.6.29, PPC no more admits passing NULL to the dev parameter of the DMA API. The result is a BUG followed by solid lock-up when the mv643xx_eth driver brings an interface up. The following patch makes the driver work on my Pegasos again; it is mostly a search and replace of NULL by mp->dev->dev.parent in dma allocation/freeing/mapping/unmapping functions. Signed-off-by:

One of the purposes of bonding is to allow for redundant links, and failover correctly if the cable is pulled. If all the members of a bonded device have no carrier present, the bonded device itself needs to report no carrier present to user space so management tools (like routing daemons) can respond. Bonding in 802.3ad mode does not work correctly for this because it incorrectly chooses a link that is down as a possible aggregator. Signed-off-by:

If bridge is configured with no STP and forwarding delay of 0 (which is typical for virtualization) then when link starts it will flood all packets for the first 20 seconds. This bug was introduced by a combination of earlier changes: * forwarding database uses hold time of zero to indicate user wants to always flood packets * optimzation of the case of forwarding delay of 0 avoids the initial timer tick The fix is to just skip all the topology change detection code if kernel STP is not being used.

Currently the bridge catches all STP packets; even if STP is turned off. This prevents other systems (which do have STP turned on) from being able to detect loops in the network. With this patch, if STP is off, then any packet sent to the STP multicast group address is forwarded to all ports. Based on earlier patch by Joakim Tjernlund with changes to go through forwarding (not local chain), and optimization that only last octet needs to be checked. Signed-off-by:

If a DHCP server is delayed, it's possible for the client to receive the DHCPOFFER after it has already sent out a new DHCPDISCOVER message from a second interface. The client then sends out a DHCPREQUEST from the second interface, but the server doesn't recognize the device and rejects the request. This patch simply tracks the current device being configured and throws away the OFFER if it is not intended for the current device. A more sophisticated approach would be to put the OFFER information into the struct ic_device rather than storing it globally. Signed-off-by:

Ian Campbell noticed that since "Eliminate thousands of warnings with gcc 3.2 build" (commit 57adc4d2 ) all WARN_ON()'s currently appear to come from warn_slowpath_null(), eg: WARNING: at kernel/softirq.c:143 warn_slowpath_null+0x1c/0x20() because now that warn_slowpath_null() is in the call path, the __builtin_return_address(0) returns that, rather than the place that caused the warning. Fix this by splitting up the warn_slowpath_null/fmt cases differently, using a common helper function, and getting the return address in the right place. This also happens to avoid the unnecessary stack usage for the non-stdargs case, and just generally cleans things up. Make the function name printout use %pS while at it.

This patch provides new heuristics for parsing both the form factor and media rotation rate ATA IDENFITY words. The reported ATA version must be 7 or greater and the device must return values defined as valid in the standard. Only then are the characteristics reported to SCSI via the VPD B1 page. This seems like a reasonable compromise to me considering that we have been shipping several kernel releases that key off the rotation rate bit without any version checking whatsoever. With no complaints so far. Signed-off-by:
