2005-09-05[PATCH] ppc32: Added support for the Book-E style Watchdog TimerKumar Gala
PowerPC 40x and Book-E processors support a watchdog timer at the processor core level. The timer has implementation dependent timeout frequencies that can be configured by software. One the first Watchdog timeout we get a critical exception. It is left to board specific code to determine what should happen at this point. If nothing is done and another timeout period expires the processor may attempt to reset the machine. Command line parameters: wdt=0 : disable watchdog (default) wdt=1 : enable watchdog wdt_period=N : N sets the value of the Watchdog Timer Period. The Watchdog Timer Period meaning is implementation specific. Check User Manual for the processor for more details. This patch is based off of work done by Takeharu Kato.

2005-08-31[PATCH] iseries_veth: Be consistent about driver name, increment versionMichael Ellerman
The iseries_veth driver tells sysfs that it's called 'iseries_veth', but if you ask it via ethtool it thinks it's called 'veth'. I think this comes from 2.4 when the driver was called 'veth', but it's definitely called 'iseries_veth' now, so fix it. To make sure we don't do it again define DRV_NAME and use it everywhere. While we're at it, change the version number to 2.0, to reflect the changes made in this patch series.

2005-08-31[PATCH] iseries_veth: Fix bogus counting of TX errorsMichael Ellerman
There's a number of problems with the way iseries_veth counts TX errors. Firstly it counts conditions which aren't really errors as TX errors. This includes if we don't have a connection struct for the other LPAR, or if the other LPAR is currently down (or just doesn't want to talk to us). Neither of these should count as TX errors. Secondly, it counts one TX error for each LPAR that fails to accept the packet. This can lead to TX error counts higher than the total number of packets sent through the interface. This is confusing for users. This patch fixes that behaviour. The non-error conditions are no longer counted, and we introduce a new and I think saner meaning to the TX counts. If a packet is successfully transmitted to any LPAR then it is transmitted and tx_packets is incremented by 1. If there is an error transmitting a packet to any LPAR then that is counted as one error, ie. tx_errors is incremented by 1.

2005-08-31[PATCH] iseries_veth: Simplify full-queue handlingMichael Ellerman
The iseries_veth driver often has multiple netdevices sending packets over a single connection to another LPAR. If the bandwidth to the other LPAR is exceeded, all the netdevices must have their queues stopped. The current code achieves this by queueing one incoming skb on the per-netdevice port structure. When the connection is able to send more packets we iterate through the port structs and flush any packet that is queued, as well as restarting the associated netdevice's queue. This arrangement makes less sense now that we have per-connection TX timers, rather than the per-netdevice generic TX timer. The new code simply detects when one of the connections is full, and stops the queue of all associated netdevices. Then when a packet is acked on that connection (ie. there is space again) all the queues are woken up.

2005-08-31[PATCH] iseries_veth: Add a per-connection ack timerMichael Ellerman
Currently the iseries_veth driver contravenes the specification in Documentation/networking/driver.txt, in that if packets are not acked by the other LPAR they will sit around forever. This patch adds a per-connection timer which fires if we've had no acks for five seconds. This is superior to the generic TX timer because it catches the case of a small number of packets being sent and never acked. This fixes a bug we were seeing on real systems, where some IPv6 neighbour discovery packets would not be acked and then prevent the module from being removed, due to skbs lying around.

2005-08-31[PATCH] iseries_veth: Use kobjects to track lifecycle of connection structsMichael Ellerman
The iseries_veth driver can attach to multiple vlans, which correspond to multiple net devices. However there is only 1 connection between each LPAR, so the connection structure may be shared by multiple net devices. This makes module removal messy, because we can't deallocate the connections until we know there are no net devices still using them. The solution is to use ref counts on the connections, so we can delete them (actually stop) as soon as the ref count hits zero. This patch fixes (part of) a bug we were seeing with IPv6 sending probes to a dead LPAR, which would then hang us forever due to leftover skbs.

2005-08-31[PATCH] iseries_veth: Make init_connection() & destroy_connection() symmetricalMichael Ellerman
This patch makes veth_init_connection() and veth_destroy_connection() symmetrical in that they allocate/deallocate the same data. Currently if there's an error while initialising connections (ie. ENOMEM) we call veth_module_cleanup(), however this will oops because we call driver_unregister() before we've called driver_register(). I've never seen this actually happen though. So instead we explicitly call veth_destroy_connection() for each connection, any that have been set up will be deallocated. We also fix a potential leak if vio_register_driver() fails.

2005-08-31[PATCH] iseries_veth: Only call dma_unmap_single() if dma_map_single() succeededMichael Ellerman

Rework the code a bit to keep the return value from dma_unmap_single() around, and then check if it's a dma_mapping_error() before we do the dma_unmap_single().

2005-08-31[PATCH] iseries_veth: Replace lock-protected atomic with an ordinary variableMichael Ellerman

2005-08-31[PATCH] iseries_veth: Remove redundant message stack lockMichael Ellerman
The iseries_veth driver keeps a stack of messages for each connection and a lock to protect the stack. However there is also a per-connection lock which makes the message stack lock redundant.

2005-08-31[PATCH] iseries_veth: Fix broken promiscuous handlingMichael Ellerman
Due to a logic bug, once promiscuous mode is enabled in the iseries_veth driver it is never disabled. The driver keeps two flags, promiscuous and all_mcast which have exactly the same effect. This is because we only ever receive packets destined for us, or multicast packets. So consolidate them into one promiscuous flag for simplicity.

2005-08-31[PATCH] iseries_veth: Try to avoid pathological reset behaviourMichael Ellerman
The iseries_veth driver contains a state machine which is used to manage how connections are setup and neogotiated between LPARs. If one side of a connection resets for some reason, the two LPARs can get stuck in a race to re-setup the connection. This can lead to the connection being declared dead by one or both ends. In practice the connection is declared dead by one or both ends approximately 8/10 times a connection is reset, although it is rare for connections to be reset. (an example here: http://michael.ellerman.id.au/files/misc/veth-trace.html) The core of the problem is that the end that resets the connection doesn't wait for the other end to become aware of the reset. So the resetting end starts setting the connection back up, and then receives a reset from the other end (which is the response to the initial reset). And so on. We're severely limited in what we can do to fix this. The protocol between LPARs is essentially fixed, as we have to interoperate with both OS/400 and old Linux drivers. Which also means we need a fix that only changes the code on one end. The only fix I've found given that, is to just blindly sleep for a bit when resetting the connection, in the hope that the other end will get itself sorted. Needless to say I'd love it if someone has a better idea. This does work, I've so far been unable to get it to break, whereas without the fix a reset of one end will lead to a dead connection ~8/10 times.

2005-08-31[PATCH] iseries_veth: Remove a FIXME WRT deletion of the ack_timerMichael Ellerman
The iseries_veth driver has a timer which we use to send acks. When the connection is reset or stopped we need to delete the timer. Currently we only call del_timer() when resetting a connection, which means the timer might run again while the connection is being re-setup. As it turns out that's ok, because the flags the timer consults have been reset. It's cleaner though to call del_timer_sync() once we've dropped the lock, although the timer may still run between us dropping the lock and calling del_timer_sync(), but as above that's ok.
