The previous umad deadlock fix left ib_umad_kill_port() still vulnerable to deadlocking. This patch fixes that by downgrading our lock to a read lock when we might end up trying to reacquire the lock for reading. Signed-off-by: NRoland Dreier <rolandd@cisco.com>

Move the computation of QP capabilities (max scatter/gather entries, max inline data, etc) into the kernel, and have the uverbs module return the values as part of the create QP response. This keeps precise knowledge of device limits in the low-level kernel driver. This requires an ABI bump, so while we're making changes, get rid of the max_sge parameter for the modify SRQ command -- it's not used and shouldn't be there.

Change the struct ib_device.resize_cq() method to take a plain integer that holds the new CQ size, rather than a pointer to an integer that it uses to return the new size. This makes the interface match the exported ib_resize_cq() signature, and allows the low-level driver to update the CQ size with proper locking if necessary. No in-tree drivers are exporting this method yet. Signed-off-by: NRoland Dreier <rolandd@cisco.com>

ib_unregister_mad_agent() completes all pending MAD sends and waits for the agent's send_handler routine to return. umad's send_handler() calls queue_packet(), which does down_read() on the port mutex to look up the agent ID. This means that the port mutex cannot be held for writing while calling ib_unregister_mad_agent(), or else it will deadlock. This patch fixes all the calls to ib_unregister_mad_agent() in the umad module to avoid this deadlock. Signed-off-by: NRoland Dreier <rolandd@cisco.com>

Add ibX_path files to debugfs that contain information about the IPoIB path cache. IPoIB ARP only gives GIDs, which the IPoIB driver must resolve to real IB paths through the ib_sa module. For debugging, when the ARP table looks OK but traffic isn't flowing, it's useful to be able to see if the resolution from GID to path worked. Also clean up the formatting of the existing _mcg debugfs files. Signed-off-by: NRoland Dreier <rolandd@cisco.com>

This patch removes almost all inclusions of linux/version.h. The 3 #defines are unused in most of the touched files. A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is unfortunatly in linux/version.h. There are also lots of #ifdef for long obsolete kernels, this was not touched. In a few places, the linux/version.h include was move to where the LINUX_VERSION_CODE was used. quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'` search pattern: /UTS_RELEASE\|LINUX_VERSION_CODE\|KERNEL_VERSION\|linux\/\(utsname\|version\).h Signed-off-by: NOlaf Hering <olh@suse.de> Signed-off-by: NAndrew Morton <akpm@osdl.org> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

Add some initial support for detecting and reporting catastrophic errors reported by Mellanox HCAs. We start a periodic timer which polls the catastrophic error reporting buffer in device memory. If an error is detected, we dump the contents of the buffer for port-mortem debugging, and report a fatal asynchronous error to higher levels. In the future we can try to recover from these errors by resetting the device, but this will require some work in higher-level code as well. Let's get this in now, so that we at least get catastrophic errors reported in logs. Signed-off-by: NRoland Dreier <rolandd@cisco.com>
