entries The gen2_basic tests check for the errno value when a CQ is resized smaller than the number of outstanding completions queue on the CQ.

2008-01-25IB/mad: Enable loopback of DR SMP responses from userspaceSteve Welch2-4/+20
The local loopback of an outgoing DR SMP response is limited to those that originate at the driver specific SMA implementation during the driver specific process_mad() function. This patch enables a returning DR SMP originating in userspace (or elsewhere) to be delivered to the local managment stack. In this specific case the driver process_mad() function does not consume or process the MAD, so a reponse mad has not be created and the original MAD must manually be copied to the MAD buffer that is to be handed off to the local agent.

2008-01-25IPoIB/cm: Add connected mode support for devices without SRQsPradeep Satyanarayana4-43/+200
Some IB adapters (notably IBM's eHCA) do not implement SRQs (shared receive queues). The current IPoIB connected mode support only works on devices that support SRQs. Fix this by adding support for using the receive queue of each connected mode receive QP. The disadvantage of this compared to using an SRQ is that it means a full queue of receives must be posted for each remote connected mode peer, which means that total memory usage is potentially much higher than when using SRQs. To manage this, add a new module parameter "max_nonsrq_conn_qp" that limits the number of connections allowed per interface. The rest of the changes are fairly straightforward: we use a table of struct ipoib_cm_rx to hold all the active connections, and put the table index of the connection in the high bits of receive WR IDs. This is needed because we cannot rely on the struct ib_wc.qp field for non-SRQ receive completions. Most of the rest of the changes just test whether or not an SRQ is available, and post receives or find received packets in the right place depending on the answer. Cleaning up dead connections actually becomes simpler, because we do not have to do the "last WQE reached" dance that is required to destroy QPs attached to an SRQ. We just move the QP to the error state and wait for all pending receives to be flushed.

Factor out the code for going through the rx_reap list of struct ipoib_cm_rx and freeing each one. This consolidates the code duplicated between ipoib_cm_dev_stop() and ipoib_cm_rx_reap() and reduces the risk of error when adding additional accounting.

2008-01-25IB/ipath: Fix crash on unload introduced by sysfs changesRoland Dreier1-1/+2
Commit 23b9c1ab ("Infiniband: make ipath driver use default driver groups.") introduced a bug in the ipath driver where ipath_device_create_group() fell through into the error path, even on success, which meant that the sysfs groups it created would always get removed right away. This made ipath_device_remove_group() hit the BUG_ON() in sysfs_remove_group() when it tried to remove those groups a second time. Correct the return path so that the groups stick around until they are supposed to be cleaned up. Signed-off-by: Roland Dreier <rolandd@cisco.com>

This can be broken down into these major areas: - Documentation updates (language translations and fixes, as well as kobject and kset documenatation updates.) - major kset/kobject/ktype rework and fixes. This cleans up the kset and kobject and ktype relationship and architecture, making sense of things now, and good documenation and samples are provided for others to use. Also the attributes for kobjects are much easier to handle now. This cleaned up a LOT of code all through the kernel, making kobjects easier to use if you want to. - struct bus_type has been reworked to now handle the lifetime rules properly, as the kobject is properly dynamic. - struct driver has also been reworked, and now the lifetime issues are resolved. - the block subsystem has been converted to use struct device now, and not "raw" kobjects. This patch has been in the -mm tree for over a year now, and finally all the issues are worked out with it. Older distros now properly work with new kernels, and no userspace updates are needed at all. - nozomi driver is added. This has also been in -mm for a long time, and many people have asked for it to go in. It is now in good enough shape to do so. - lots of class_device conversions to use struct device instead. The tree is almost all cleaned up now, only SCSI and IB is the remaining code to fix up... * git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-2.6: (196 commits) Driver core: coding style fixes Kobject: fix coding style issues in kobject c files Kobject: fix coding style issues in kobject.h Driver core: fix coding style issues in device.h spi: use class iteration api scsi: use class iteration api rtc: use class iteration api power supply : use class iteration api ieee1394: use class iteration api Driver Core: add class iteration api Driver core: Cleanup get_device_parent() in device_add() and device_move() UIO: constify function pointer tables Driver Core: constify the name passed to platform_device_register_simple driver core: fix build with SYSFS=n sysfs: make SYSFS_DEPRECATED depend on SYSFS Driver core: use LIST_HEAD instead of call to INIT_LIST_HEAD in __init kobject: add sample code for how to use ksets/ktypes/kobjects kobject: add sample code for how to use kobjects in a simple manner. kobject: update the kobject/kset documentation kobject: remove old, outdated documentation. ...

2008-01-24Driver core: fix race in __device_release_driverAlan Stern1-3/+2
This patch (as1013) was suggested by David Woodhouse; it fixes a race in the driver core. If a device is unregistered at the same time as its driver is unloaded, the driver's code pages may be unmapped while the remove method is still running. The calls to get_driver() and put_driver() were intended to prevent this, but they don't work if the driver's module count has already dropped to 0. Instead, the patch keeps the device on the driver's list until after the remove method has returned. This forces the necessary synchronization to occur.
