The newest device firmware stores IB vs. Ethernet protocol in two bits in members_count field of multicast group table (0: Infiniband, 1: Ethernet). When changing the QP members count for a multicast group, it important not to reset this information. When calling multicast attach first time, the protocol type should be specified. In this patch we always set it IB, but in the future we will handle Ethernet too. When looking for a QP, the protocol type shoud be checked too.

This patch allows IBoE traffic to be encapsulated in 802.1Q tagged VLAN frames. The VLAN tag is encoded in the GID and derived from it by a simple computation. The netdev notifier callback is modified to catch VLAN device addition/removal and the port's GID table is updated to reflect the change, so that for each netdevice there is an entry in the GID table. When the port's GID table is exhausted, GID entries will not be added. Only children of the main interfaces can add to the GID table; if a VLAN interface is added on another VLAN interface (e.g. "vconfig add eth2.6 8"), then that interfaces will not add an entry to the GID table.

Add support for IBoE to mlx4_ib. The bulk of the code is handling the new address vector fields; mlx4 needs the MAC address of a remote node to include it in a WQE (for datagrams) or in the QP context (for connected QPs). Address resolution is done by assuming all unicast GIDs are either link-local IPv6 addresses. Multicast group attach/detach needs to update the NIC's multicast filters; but since attaching a QP to a multicast group can be done before the QP is bound to a port, for IBoE we need to keep track of all multicast groups that a QP is attached too before it transitions from INIT to RTR (since it does not have a port in the INIT state).

The Node Description cannot be changed via MADs (it is read-only). Until now, it was changed in the driver via sysfs, and the new Node Description was simply inserted by the driver into MAD responses (replacing the description returned by FW). System startup scripts use the sysfs interface to change the node description at driver startup to show the hostname, etc. However, this has a race condition: the SM could discover the original FW node description rather than the system-specific description if it queried the port before the startup scripts finish running. For mlx4, we fix this with a new FW command (SET_NODE) that allows passing the new node description to FW. When this command is invoked, FW sends a trap 144 to the SM. When it gets this trap, the SM can query the node to obtain the new node description -- thus eliminating the effects of the race. This patch simply calls SET_NODE command when a new node description is entered via sysfs (thus causing trap 144 to be issued by the FW). We ignore all failures of the SET_NODE command (including those caused by using a device FW that predates the SET_NODE command), since in that case things work just as before.

Add a new parameter to ib_register_device() so that low-level device drivers can pass in a pointer to a callback function that will be called for each port that is registered in sysfs. This allows low-level device drivers to create files in /sys/class/infiniband/<hca>/ports/<N>/ without having to poke through the internals of the RDMA sysfs handling. There is no need for an unregister function since the kobject reference will go to zero when ib_unregister_device() is called.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

Current code has a limitation: an LSO header is not allowed to cross a 64 byte boundary. This patch removes this limitation by setting the WQE RR for large headers thus allowing LSO headers of any size. The extra buffer reserved for MLX4_IB_QP_LSO QPs has been doubled, from 64 to 128 bytes, assuming this is reasonable upper limit for header length. Also, this patch will cause IB_DEVICE_UD_TSO to be set only for HCA FW versions that set MLX4_DEV_CAP_FLAG_BLH; e.g. FW version 2.6.000 and higher.

Userspace apps are supposed to release all ib device resources if they receive a fatal async event (IBV_EVENT_DEVICE_FATAL). However, the app has no way of knowing when the device has come back up, except to repeatedly attempt ibv_open_device() until it succeeds. However, currently there is no protection against the open succeeding while the device is in being removed following the fatal event. In this case, the open will succeed, but as a result the device waits in the middle of its removal until the new app releases its resources -- and the new app will not do so, since the open succeeded at a point following the fatal event generation. This patch adds an "active" flag to the device. The active flag is set to false (in the fatal event flow) before the "fatal" event is generated, so any subsequent ibv_dev_open() call to the device will fail until the device comes back up, thus preventing the above deadlock.

The struct mlx4_interface.event() method was supposed to get an enum mlx4_dev_event, but the driver code was actually passing in the hardware enum mlx4_event values. Fix up the callers of mlx4_dispatch_event() so that they pass in the right type of value, and fix up the event method in mlx4_ib so that it can handle the enum mlx4_dev_event values. This eliminates the need for the subtype parameter to the event method, so remove it.
