2008-12-01IB/mlx4: Fix MTT leakage in resize CQJack Morgenstein
When resizing a CQ, MTTs associated with the old CQE buffer were not freed. As a result, if any app used resize CQ repeatedly, all MTTs were eventually exhausted, which led to all memory registration operations failing until the driver is reloaded. Once the RESIZE_CQ command returns successfully from FW, FW no longer accesses the old CQ buffer, so it is safe to deallocate the MTT entries used by the old CQ buffer. Finally, if the RESIZE_CQ command fails, the MTTs allocated for the new CQEs buffer also need to be de-allocated. This fixes <https://bugs.openfabrics.org/show_bug.cgi?id=1416>.

2008-11-12IPoIB: Fix crash in path_rec_completion()Yossi Etigin
Fix a crash in path_rec_completion() during an SM up/down loop. If more than one path record request is issued, the first completion releases path->done, allowing ipoib_flush_paths() to free the path, and thus corrupting it for the second completion. Commit ee1e2c82 ("IPoIB: Refresh paths instead of flushing them on SM change events") added the field path->valid and changed the test "if (!path)" to "if (!path || !path->valid)". This change made it possible for a path with an outstanding query to pass the test and issue another query on the same path. Having two queries on the same path leads to a crash.

2008-11-12IPoIB: Fix hang in ipoib_flush_paths()Yossi Etigin
ipoib_flush_paths() can hang during an SM up/down loop: if path_rec_start() fails (for instance, because there is no sm_ah), the path is still added to the path list by neigh_add_path(). Then, ipoib_flush_paths() will wait for path->done, but it will never complete because the request was not issued at all. Fix this by completing path->done if issuing the query fails.

2008-11-12IPoIB: Don't enable NAPI when it's already enabledYossi Etigin
If a P_Key is not present when an interface is created, ipoib_open() will return after doing napi_enable(). ipoib_open() will be called again from ipoib_pkey_poll() when the P_Key appears, after NAPI has already been enabled, and try to enable it again. This triggers a BUG_ON() in napi_enable(). Fix this by moving the call to napi_enable() to after the test for P_Key presence.

2008-11-12RDMA/cxgb3: Fix deadlock in iw_cxgb3 (hang when configuring interface)Steve Wise
When the iw_cxgb3 module's cxgb3_client "add" func gets called by the cxgb3 module, the iwarp driver ends up calling the ethtool ops get_drvinfo function in cxgb3 to get the fw version and other info. Currently the iwarp driver grabs the rtnl lock around this down call to serialize. As of 2.6.27 or so, things changed such that the rtnl lock is held around the call to the netdev driver open function. Also the cxgb3_client "add" function doesn't get called if the device is down. So, if you load cxgb3, then load iw_cxgb3, then ifconfig up the device, the iw_cxgb3 add func gets called with the rtnl_lock held. If you load cxgb3, ifconfig up the device, then load iw_cxgb3, the add func gets called without the rtnl_lock held. The former causes the deadlock, the latter does not. In addition, there are iw_cxgb3 sysfs handlers that also can call down into cxgb3 to gather the fw and hw versions. These can be called concurrently on different processors and at any time. Thus we need to push this serialization down in the cxgb3 driver get_drvinfo func. The fix is to remove rtnl lock usage, and use a per-device lock in cxgb3.

2008-11-01saner FASYNC handling on file closeAl Viro
As it is, all instances of ->release() for files that have ->fasync() need to remember to evict file from fasync lists; forgetting that creates a hole and we actually have a bunch that *does* forget. So let's keep our lives simple - let __fput() check FASYNC in file->f_flags and call ->fasync() there if it's been set.

2008-10-22IB/ehca: Reject dynamic memory add/remove when ehca adapter is presentStefan Roscher
Since the ehca device driver does not support dynamic memory add and remove operations, the driver must explicitly reject such requests in order to prevent unpredictable behaviors related to existing memory regions that cover all of memory being used by InfiniBand protocols in the kernel. The solution (for now at least) is to add a memory notifier to the ehca device driver and if a request for dynamic memory add or remove comes in, ehca will always reject it. The user can add or remove memory by hot-removing the ehca adapter, performing the memory operation, and then hot-adding the ehca adapter back.

2008-10-22IB/ehca: Fix reported max number of QPs and CQs in systems with >1 adapterStefan Roscher
Because ehca adapters can differ in the maximum number of QPs and CQs we have to save the maximum number of these ressources per adapter and not globally per ehca driver. This fix introduces 2 new members to the shca structure to store the maximum value for QPs and CQs per adapter. The module parameters are now used as initial values for those variables. If a user selects an invalid number of CQs or QPs we don't print an error any longer, instead we will inform the user with a warning and set the values to the respective maximum supported by the HW.

2008-10-20x86: sysfs: kill owner field from attributeParag Warudkar
Tejun's commit 7b595756ec1f49e0049a9e01a1298d53a7faaa15 made sysfs attribute->owner unnecessary. But the field was left in the structure to ease the merge. It's been over a year since that change and it is now time to start killing attribute->owner along with its users - one arch at a time! This patch is attempt #1 to get rid of attribute->owner only for CONFIG_X86_64 or CONFIG_X86_32 . We will deal with other arches later on as and when possible - avr32 will be the next since that is something I can test. Compile (make allyesconfig / make allmodconfig / custom config) and boot tested. akpm: the idea is that we put the declaration of sttribute.owner inside `#ifndef CONFIG_X86'.
