* [PATCH] IB uverbs: hook up Kconfig/MakefileRoland Dreier2005-07-071-1/+4
| | | | | | | | Hook up InfiniBand userspace verbs to Kconfig and the make system. Signed-off-by: Roland Dreier <rolandd@cisco.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] IB uverbs: memory pinning implementationRoland Dreier2005-07-071-0/+221
| | | | | | | | | | Add support for pinning userspace memory regions and returning a list of pages in the region. This includes tracking pinned memory against vm_locked and preventing unprivileged users from exceeding RLIMIT_MEMLOCK.

* [PATCH] IB uverbs: core implementationRoland Dreier2005-07-073-0/+1836
| | | | | | | | | | Add the core of the InfiniBand userspace verbs implementation, including creating character device nodes, dispatching requests from userspace, and passing event notifications back up to userspace.

* [PATCH] IB uverbs: update kernel midlayer for new APIRoland Dreier2005-07-071-12/+20
| | | | | | | | | | | Update kernel InfiniBand midlayer to compile against the updated API for low-level drivers. This just amounts to passing NULL for all userspace-related parameters, and setting userspace-related structure members to NULL.

* [PATCH] IB: Fix pack/unpack when size_bits == 64Roland Dreier2005-06-271-2/+2
| | | | | | | | Fix handling of fields with size_bits == 64. Pointed out by Hal Rosenstock. Signed-off-by: Roland Dreier <rolandd@cisco.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] IB: Fix race in sa_queryRoland Dreier2005-06-271-5/+13
| | | | | | | | | | | Use a copy of the id we'll return to the consumer so that we don't dereference query->sa_query after calling send_mad(). A completion may occur very quickly and end up freeing the query before we get to do anything after send_mad().

| | | | | | | | | sysfs: fix the rest of the kernel so if an attribute doesn't implement show or store method read/write will return -EIO instead of 0 or -EINVAL or -EPERM. Signed-off-by: Dmitry Torokhov <dtor@mail.ru> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* [PATCH] IB: fix potential ib_umad leakRoland Dreier2005-05-251-0/+4
| | | | | | | | | Free all unclaimed MAD receive buffers when userspace closes our file so we don't leak memory. Signed-off-by: Roland Dreier <roland@topspin.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] IB: allow NULL sa_query callbacksRoland Dreier2005-05-251-17/+18
| | | | | | | | | | | | | | | Check if a client passes a NULL callback into an SA query, and if so, never call back. This fixes an oops if someone unloads ib_ipoib and ib_sa in rapid succession. ib_ipoib does an MCMember delete with a NULL callback and 0 timeout on unload, which is usually fine since the delete completes successfully. However, if ib_sa is unloaded immediately afterwards, the delete will be canceled and ib_sa will try to call the (now already unloaded) ib_ipoib module back with the cancel completion, which triggers the oops.

* [PATCH] IB: Fix user MAD registrations with class 0Roland Dreier2005-04-161-6/+8
| | | | | | | | | | Fix handling of MAD agent registrations with mgmt_class == 0. In this case ib_umad should pass a NULL registration request to the MAD core rather than a request with mgmt_class set to 0.

| | | | | | | | | | | Replace the *wc field in ib_mad_recv_wc from pointing to a structure on the stack to one allocated with the received MAD buffer.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
