[HW, TOOLS] Improve VSTAT output in case of a driver startup failure. [MLNX: 2819]
When low level drivers fail on startup, which usually happens upon an incorrect FW, they report to all the above stack a dev_id of the burning device ("livefish") and imitate such a device thereafter. It was done in order to allow to all the upper level drivers to start their work.
VSTAT shows in this case the dev_id of a "livefish", which is a bit misleading.
This patch fixes this behavior. VSTAT will now show the real dev_id. The drivers still imitate the "livefish" device. The detailed message about the startup failure can be found in System Event Log (as it always was).
[MLX4] added a possibility to register event handler with MLX4_BUS driver. [MLNX:2786]
It is an extension of the Ethernet interface of mlx4_bus driver.
The mlx4_eth handler is called on DPC level upon asynchronous events like PORT_UP/PORT_DOWN, passing event data and the callback context parameter, set upon registration.
uvp/av: change create/modify calls to take SGID index
The uvp requires the SGID index to create/modify address handles.
Modify the API and UVPs to take the SGID index as input. This avoids
the UVP needing to cache the CA attributes, which can lead to accessing
a stale GID table. The SGID index is passed into the UVP through the
resv1 field of the GRH.
This adds the patch to make this change.

[WinOF] buildrelease no longer contains uglt hack to work around XP32 WSD build problems.
Added a 2nd cmd line arg to set OPENIB_REV value when building installers. Fix eliminates folder structure dependency, making the script more useful to a wider audience.
[DAPL2] DAPL2 debug cleanup, along with patches to IBAL provider to correctly handle accept side private_data.
Fixed the async QP & CQ error handlers as they had not been updated with latest typedef's (ib_async_qp_handler_t & ib_async_cq_handler_t), hence calling arg mismatch vs. handling definitions. Resulted in bad EP pointer dereference during Async QP error handling.
Added debug value DAPL_DBG_EVD_DEQUEUE to throttle debug output when watching EVD dequeue operations.
The SGID index can change dynamically, so look up the correct index when creating an address vector. The index is passed into the UVP in the resv2 field of the grh.

[WinOF] for XP32 builds, place holder files (until someone comes up with a better plan) utilized by makebin to cover the case of WSD not available for XP32. netipoib-xp32.inf intentionally contains 64 bit sections as to minimize differences between it and netipoib.inf file.
[IBAL] Limit time spent at DISPATCH_LEVEL when processing MADs.
In working with some switch SMs, I found that under stress the QP0 MAD processing could get delayed by eternal QP1 MAD processing (from hitting the SA for path queries). This caused the SMs to remove the node from the fabric (multicast group membership, etc) because it appeared unreachable.
This patch adds a DPC for QP0 and QP1 to the SMI, and limits the SMI to processing 16 MADs before re-queueing the DPC to the DPC queue.
Because QP0 processing is crucial to the fabric operating properly, the QP0 DPC is set to high importance so that it always gets queued to the front of the DPC queue, pre-empting any QP1 processing (among other things).
In any case, with this patch all my changes have now been mailed to the list.

Warning C4826 warns you if you have signed pointer extension when a 32-bit pointer is extended to 64-bits. This patch turns the warning on by default (for any users of complib), and fixes all instances of problematic code. It also eradicates __ptr64 usage from the Qlogic VNIC driver.
Code affected:
- IBAL
- MTHCA
- MLX4
- QLGCVNIC
Note that I didn't change DAPL because it's licensed under the CPL and not BSD. So someone else will have to fix that. In fact, DAPL should probably just go back into the SourceForge project rather than being duplicated everywhere. Code in the WinOF SVN should be BSD only according to the contributor's agreement.

The UAL_NDI_NOOP IOCTL handler was added to allow memory registration in user-mode to notify a client using an I/O completion port. This patch extends the functionality to allow the IOCTL to return either STATUS_SUCCESS or STATUS_TIMEOUT. The STATUS_TIMEOUT facility is used by the NetworkDirect provider when IBAT returns pending. It's crude, but gets the job done.

[IBAL] Fix TO_LONG_PTR use in IOCTLs. Re-applied 1387 patch.
Some IOCTLs transfer API structures with embedded pointers. These embedded pointers use the TO_LONG_PTR macro to pad everything out so that __ptr64 isn't used. The idea here is fine, but the change to eliminate the __ptr64 was riddled with problems that weren't caught by the find/replace brute force code changes.
Oops, the mem_create in the IOCTL buffer was overwritten with the caller's structure, which may have uninitialized padding. This isn't subsequently cleared, effectively defeating the purpose of the memclr.
Ah, close but not quite - you have the assignment, but it only assigns the pointer part of the TO_LONG_PTR union. The padding is still a copy of the user's structure, potentially giving an invalid handle in the kernel. All uses of HDL_TO_PTR were eliminated as they didn't actually accomplish anything.
This patch fixes this, and always uses the 'padding' field of the TO_LONG_PTR union so that the value is always fully set.
There's also a bug fixed in UD work requests that get sent via IOCTL - the AV handle was never swizzled to its appropriate kernel handle.

[IBAL] Remove TO_LONG_PTR from IOCTL structures. Re-applied 1386 patch with out SMI changes.
This patch removes all instances of TO_LONG_PTR from internal IOCTL structures. The only place TO_LONG_PTR should be used is in public structures that contain pointers and are exchanged between user-mode and kernel-mode. Actually, the code should ideally have proxy structures for such API structures into which API structure members
are copied member-wise, and whose size is fixed. Unused pointers should be stripped from the IOCTL proxy structures. But that's a change for some other time...

Part of cleaning up the __ptr64 stuff properly - rather than use the TO_LONG_PTR in the ci_umv_buf_t structure, use uint64_t.
The problem with using TO_LONG_PTR in structures that are exchanged between 32-bit clients and 64-bit drivers is that care must be taken to ensure that the upper 'padding' bytes are cleared properly.
Making the field a uint64_t makes it fool proof (though it does require casting, but at least the compiler will trap errors unlike for the padding.)

In my previous patch "Fix race reading/setting connection ID" I incorrectly stated that the patch changed the semantics of creation/destruction of the CEPs by providing the destroy callback at CEP creation time. It didn't, but this patch does.
Note that it also backs out the "Cleanup CEPs after child objects have been destroyed" changes, as those actually introduced the following issue:
UM listen CEPs are not tracked in AL's handle table, but can queue MADs which take a reference on the AL instance. AL's destroying callback must cleanup the CEPs to free the MADs in order for the ref count to reach zero.
The root problem, and the iterations of the fix that are apparent in the patch sequence has to do with race conditions cleaning up QPs while CM messages are being received and processed. First there was the issue of the CID stored in the QP having two reserved states and races checking/assigning this value. This was fixed (successfully) by pushing checks into the CEP manager, protected by the CEP manager's spinlock. Next was the issue that a reference on the QP is taken when the CEP is bound to a QP, but if AL was destroyed the CEP cleanup in AL would blow away the CEPs before the QPs were done being destroyed. This would leak a reference count on the QP since the CEP was destroyed without a destroy callback. The change that added a cleanup callback to AL was the first (failed) attempt to fix this (for the reasons listed above). This patch is the successful attempt to fix this, as it sets the destroy callback at creation time. No matter what path destroys the CEP, if a destroy callback was taken (because some object has a reference for the CEP), the destroy callback will always be invoked.

[CORE, TESTS] This patch adds a library and test utility that performs IP to IB address translation without going to the SA for DAPL ATS service records.
It's a sequence of operations between the IP helper library and IPoIB.
1. Get the local IPoIB port's IB address information (GID).
2. Lookup the destination MAC address via the IP Helper functions, send ARP if needed 3. Ask IPoIB for the destination IB address information given the destination Ethernet MAC.
As input, the IBAT library takes two IP addresses (v4 or v6). As output, it returns two GIDs (as IN6_ADDRs), as well as the pkey.
There's a test program, wherebu, that will exercise the IBAT library.
Note that there is special code for Windows Vista/Server 2008 to take advantage of newer functionality in the IP Helper library. Without this lookups get quite slow as you increase the number of nodes. On our 256 node cluster the Windows Server 2008 code path performed an order of magnitude better than the Windows Server 2003 code path.
There will be a follow up patch that moves WSD over to using this library.
