2006-09-23RDMA: iWARP Core Changes.Tom Tucker1-1/+2
Modifications to the existing rdma header files, core files, drivers, and ulp files to support iWARP, including: - Hook iWARP CM into the build system and use it in rdma_cm. - Convert enum ib_node_type to enum rdma_node_type, which includes the possibility of RDMA_NODE_RNIC, and update everything for this.

2006-09-23IB: Whitespace fixesRoland Dreier1-3/+3
Remove some trailing whitespace that has snuck in despite the best efforts of whitespace=error-all. Also fix a few other whitespace bogosities. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-06-18IB/ucm: Get rid of duplicate P_Key parameterSean Hefty1-1/+0
The P_Key is provided into a SIDR REQ in two places, once as a parameter, and again in the path record. Remove the P_Key as a parameter and always use the one given in the path record. This change has no practical effect on ABI functionality. Signed-off-by: Sean Hefty <sean.hefty@intel.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-06-18IB/ucm: convert semaphore to mutexSean Hefty1-16/+16
Convert semaphore in ib_ucm_file to a real mutex. Signed-off-by: Sean Hefty <sean.hefty@intel.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-06-18IB/cm: Match connection requests based on private dataSean Hefty1-1/+18
Extend matching connection requests to listens in the InfiniBand CM to include private data checks. This allows applications to listen on the same service identifier, with private data directing the request to the appropriate application.

2006-06-18IB: common handling for marshalling parameters to/from userspaceSean Hefty1-117/+14
Provide common handling for marshalling data between userspace clients and kernel InfiniBand drivers. Signed-off-by: Sean Hefty <sean.hefty@intel.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-05-13IB: refcount race fixesSean Hefty1-5/+7
Fix race condition during destruction calls to avoid possibility of accessing object after it has been freed. Instead of waking up a wait queue directly, which is susceptible to a race where the object is freed between the reference count going to 0 and the wake_up(), use a completion to wait in the function doing the freeing.

2006-02-06[PATCH] IB: fix up major/minor sysfs interface for IB coreGreg Kroah-Hartman1-12/+1
Current IB code doesn't work with userspace programs that listen only to the kernel event netlink socket as it is trying to create its own dev interface. This small patch fixes this problem, and removes some unneeded code as the driver core handles this logic for you automatically.

2005-11-02[IB] kzalloc() conversionsRoland Dreier1-6/+3
Replace kmalloc()+memset(,0,) with kzalloc(), for a net savings of 35 source lines and about 500 bytes of text. Signed-off-by: Roland Dreier <rolandd@cisco.com>

2005-10-24[IB] Add idr_destroy() calls on module unloadRoland Dreier1-0/+1
Add idr_destroy() calls to the module_exit() functions of the four IB driver modules that use idrs, so we don't leak idr_layer_cache objects when these modules are unloaded. Signed-off-by: Roland Dreier <rolandd@cisco.com>

2005-09-07[PATCH] IB: Add user-supplied context to userspace CM ABISean Hefty1-99/+188
- Add user specified context to all uCM events. Users will not retrieve any events associated with the context after destroying the corresponding cm_id. - Provide the ib_cm_init_qp_attr() call to userspace clients of the CM. This call may be used to set QP attributes properly before modifying the QP. - Fixes some error handling synchonization and cleanup issues. - Performs some minor code cleanup.

2005-08-27[PATCH] IB: fix userspace CM deadlockSean Hefty1-307/+157
Fix deadlock condition resulting from trying to destroy a cm_id from the context of a CM thread. The synchronization around the ucm context structure is simplified as a result, and some simple code cleanup is included.
