2009-05-18pkt_sched: gen_estimator: use 64 bit intermediate counters for bpsEric Dumazet
gen_estimator can overflow bps (bytes per second) with Gb links, while it was designed with a u32 API, with a theorical limit of 34360Mbit (2^32 bytes) Using 64 bit intermediate avbps/brate counters can allow us to reach this theorical limit.

2009-05-18sch_teql: should not dereference skb after ndo_start_xmit()Eric Dumazet
It is illegal to dereference a skb after a successful ndo_start_xmit() call. We must store skb length in a local variable instead. Bug was introduced in 2.6.27 by commit 0abf77e55a2459aa9905be4b226e4729d5b4f0cb (net_sched: Add accessor function for packet length for qdiscs) Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

2009-05-18tcp: fix MSG_PEEK race checkIlpo Järvinen
Commit 518a09ef11 (tcp: Fix recvmsg MSG_PEEK influence of blocking behavior) lets the loop run longer than the race check did previously expect, so we need to be more careful with this check and consider the work we have been doing. I tried my best to deal with urg hole madness too which happens here: if (!sock_flag(sk, SOCK_URGINLINE)) { ++*seq; ... by using additional offset by one but I certainly have very little interest in testing that part.

2009-05-17mv643xx_eth: fix PPC DMA breakageGabriel Paubert
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.

2009-05-17bonding: fix link down handling in 802.3ad modeStephen Hemminger
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.

2009-05-17bridge: fix initial packet flood if !STPStephen Hemminger
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.

2009-05-17bridge: relay bridge multicast pkgs if !STPStephen Hemminger
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.

2009-05-17ipconfig: handle case of delayed DHCP serverChris Friesen
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.

2009-05-16Fix caller information for warn_slowpath_nullLinus Torvalds
Ian Campbell noticed that since "Eliminate thousands of warnings with gcc 3.2 build" (commit 57adc4d2dbf968fdbe516359688094eef4d46581) 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.

2009-05-15libata: Media rotation rate and form factor heuristicsMartin K. Petersen
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: Martin K. Petersen <martin.petersen@oracle.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2009-05-15libata: Report disk alignment and physical block sizeMartin K. Petersen
For disks with 4KB sectors, report the correct block size and alignment when filling out the READ CAPACITY(16) response. This patch is based upon code from Matthew Wilcox' 4KB ATA tree. I fixed the bug I reported a while back caused by ATA and SCSI using different approaches to describing the alignment. Signed-off-by: Martin K.

2009-05-15sata_fsl: Fix the command description of FSL SATA controllerDave Liu
The bit 11 of command description is reserved bit in Freescale SATA controller and needs to be set to '1'. This is needed to make sure the last write from the controller to the buffer descriptor is seen before an interrupt is raised.

2009-05-15devpts: correctly set default optionsSukadev Bhattiprolu
devpts_get_sb() calls memset(0) to clear mount options and calls parse_mount_options() if user specified any mount options. The memset(0) is bogus since the 'mode' and 'ptmxmode' options are non-zero by default. parse_mount_options() restores options to default anyway and can properly deal with NULL mount options. So in devpts_get_sb() remove memset(0) and call parse_mount_options() even for NULL mount options. Bug reported by Eric Paris: http://lkml.org/lkml/2009/5/7/448.
