In i40iw_alloc_resource(), ensure that the update to req_resource_num is protected by the lock.

2016-08-23i40iw: Change mem_resources pointer to a u8Shiraz Saleem
iwdev->mem_resources is incorrectly defined as an unsigned long instead of u8. As a result, the offset into the dynamic allocated structures in i40iw_initialize_hw_resources() is incorrectly calculated and would lead to writing of memory regions outside of the allocated buffer.

2016-08-22iw_cxgb4: use the MPA initiator's IRD if < our ORDSteve Wise
The i40iw initiator sends an MPA-request with ird=16 and ord=16. The cxgb4 responder sends an MPA-reply with ord = 32 causing i40iw to terminate due to insufficient resources. The logic to reduce the ORD to <= peer's IRD was wrong.

The i40iw initiator sends an MPA-request with ird = 63, ord = 63. The cxgb4 responder sends a RST. Since the inbound ord=63 and it exceeds the max_ird/c4iw_max_read_depth (=32 default), chelsio decides to abort. Instead, cxgb4 should adjust the ord/ird down before presenting it to the ULP.

2016-08-22IB/hfi1: Fix mm_struct use after freeIra Weiny
Testing with CONFIG_SLUB_DEBUG_ON=y resulted in the kernel panic below. This is the result of the mm_struct sometimes being free'd prior to hfi1_file_close being called. This was due to the combination of 2 reasons: 1) hfi1_file_close is deferred in process exit and it therefore may not be called synchronously with process exit. 2) exit_mm is called prior to exit_files in do_exit. Normally this is ok however, our kernel bypass code requires us to have access to the mm_struct for house keeping both at "normal" close time as well as at process exit. Therefore, the fix is to simply keep a reference to the mm_struct until we are done with it.

2016-08-22IB/rdmvat: Fix double vfree() in rvt_create_qp() error pathMike Marciniszyn
The unwind logic for creating a user QP has a double vfree of the non-shared receive queue when handling a "too many qps" failure. The code unwinds the mmmap info by decrementing a reference count which will call rvt_release_mmap_info() which in turn does the vfree() of the r_rq.wq. The unwind code then does the same free. Fix by guarding the vfree() with the same test that is done in close and only do the vfree() if qp->ip is NULL.

2016-08-22IB/hfi1: Improve J_KEY generationMitko Haralanov
Previously, J_KEY generation was based on the lower 16 bits of the user's UID. While this works, it was not good enough as a non-root user could collide with a root user given a sufficiently large UID. This patch attempt to improve the J_KEY generation by using the following algorithm: The 16 bit J_KEY space is partitioned into 3 separate spaces reserved for different user classes: * all users with administtor privileges (including 'root') will use J_KEYs in the range of 0 to 31, * all kernel protocols, which use KDETH packets will use J_KEYs in the range of 32 to 63, and * all other users will use J_KEYs in the range of 64 to 65535. The above separation is aimed at preventing different user levels from sending packets to each other and, additionally, separate kernel protocols from all other types of users. The later is meant to prevent the potential corruption of kernel memory by any other type of user.

This is an entirely new driver instead of yet another set of patches to sb_edac.c because: 1) Mapping from PCI devices to socket/memory controller is significantly different. Skylake scatters devices on a socket across a number of PCI buses. 2) There is an extra level of interleaving via the "mcroute" register that would be a little messy to squeeze into the old driver. 3) Validation is getting too expensive.

2016-08-20parisc: Fix order of EREFUSED define in errno.hHelge Deller
When building gccgo in userspace, errno.h gets parsed and the go include file sysinfo.go is generated. Since EREFUSED is defined to the same value as ECONNREFUSED, and ECONNREFUSED is defined later on in errno.h, this leads to go complaining that EREFUSED isn't defined yet. Fix this trivial problem by moving the define of EREFUSED down after ECONNREFUSED in errno.h (and clean up the indenting while touching this line).

2016-08-19Make the hardened user-copy code depend on having a hardened allocatorLinus Torvalds
The kernel test robot reported a usercopy failure in the new hardened sanity checks, due to a page-crossing copy of the FPU state into the task structure. This happened because the kernel test robot was testing with SLOB, which doesn't actually do the required book-keeping for slab allocations, and as a result the hardening code didn't realize that the task struct allocation was one single allocation - and the sanity checks fail. Since SLOB doesn't even claim to support hardening (and you really shouldn't use it), the straightforward solution is to just make the usercopy hardening code depend on the allocator supporting it.
