Pull rdma fixes from Jason Gunthorpe: "Just three small last minute regressions that were found in the last week. The Broadcom fix is a bit big for rc7, but since it is fixing driver crash regressions that were merged via netdev into rc1, I am sending it. - bnxt netdev changes merged this cycle caused the bnxt RDMA driver to crash under certain situations - Arnd found (several, unfortunately) kconfig problems with the patches adding INFINIBAND_ADDR_TRANS. Reverting this last part, will fix it more fully outside -rc. - Subtle change in error code for a uapi function caused breakage in userspace. This was bug was subtly introduced cycle" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: IB/core: Fix error code for invalid GID entry IB: Revert "remove redundant INFINIBAND kconfig dependencies" RDMA/bnxt_re: Fix broken RoCE driver due to recent L2 driver changes

IB: Revert "remove redundant INFINIBAND kconfig dependencies"

2018-05-28T16:40:16+00:00

Several subsystems depend on INFINIBAND_ADDR_TRANS, which in turn depends on INFINIBAND. However, when with CONFIG_INIFIBAND=m, this leads to a link error when another driver using it is built-in. The INFINIBAND_ADDR_TRANS dependency is insufficient here as this is a 'bool' symbol that does not force anything to be a module in turn. fs/cifs/smbdirect.o: In function `smbd_disconnect_rdma_work': smbdirect.c:(.text+0x1e4): undefined reference to `rdma_disconnect' net/9p/trans_rdma.o: In function `rdma_request': trans_rdma.c:(.text+0x7bc): undefined reference to `rdma_disconnect' net/9p/trans_rdma.o: In function `rdma_destroy_trans': trans_rdma.c:(.text+0x830): undefined reference to `ib_destroy_qp' trans_rdma.c:(.text+0x858): undefined reference to `ib_dealloc_pd' Fixes: 9533b292a7ac ("IB: remove redundant INFINIBAND kconfig dependencies") Signed-off-by: Arnd Bergmann Acked-by: Greg Thelen Signed-off-by: Jason Gunthorpe

nvme: add quirk to force medium priority for SQ creation

2018-05-11T19:37:14+00:00

Some P3100 drives have a bug where they think WRRU (weighted round robin) is always enabled, even though the host doesn't set it. Since they think it's enabled, they also look at the submission queue creation priority. We used to set that to MEDIUM by default, but that was removed in commit 81c1cd98351b. This causes various issues on that drive. Add a quirk to still set MEDIUM priority for that controller.

nvme: Fix sync controller reset return

2018-05-11T16:51:45+00:00

If a controller reset is requested while the device has no namespaces, we were incorrectly returning ENETRESET. This patch adds the check for ADMIN_ONLY controller state to indicate a successful reset.

INFINIBAND_ADDR_TRANS depends on INFINIBAND. So there's no need for options which depend INFINIBAND_ADDR_TRANS to also depend on INFINIBAND. Remove the unnecessary INFINIBAND depends. Signed-off-by: Greg Thelen Signed-off-by: Doug Ledford

nvme: fix use-after-free in nvme_free_ns_head

2018-05-07T14:25:08+00:00

Currently only nvme_ctrl will take a reference counter of nvme_subsystem, nvme_ns_head also needs it. Otherwise nvme_free_ns_head will access the nvme_subsystem.ns_ida which has been freed by __nvme_release_subsystem after all the reference of nvme_subsystem have been released by nvme_free_ctrl. This could cause memory corruption.

Pull rdma fixes from Doug Ledford: "This is our first pull request of the rc cycle. It's not that it's been overly quiet, we were just waiting on a few things before sending this off. For instance, the 6 patch series from Intel for the hfi1 driver had actually been pulled in on Tuesday for a Wednesday pull request, only to have Jason notice something I missed, so we held off for some testing, and then on Thursday had to respin the series because the very first patch needed a minor fix (unnecessary cast is all). There is a sizable hns patch series in here, as well as a reasonably largish hfi1 patch series, then all of the lines of uapi updates are just the change to the new official Linux-OpenIB SPDX tag (a bunch of our files had what amounts to a BSD-2-Clause + MIT Warranty statement as their license as a result of the initial code submission years ago, and the SPDX folks decided it was unique enough to warrant a unique tag), then the typical mlx4 and mlx5 updates, and finally some cxgb4 and core/cache/cma updates to round out the bunch. None of it was overly large by itself, but in the 2 1/2 weeks we've been collecting patches, it has added up :-/. As best I can tell, it's been through 0day (I got a notice about my last for-next push, but not for my for-rc push, but Jason seems to think that failure messages are prioritized and success messages not so much). It's also been through linux-next. And yes, we did notice in the context portion of the CMA query gid fix patch that there is a dubious BUG_ON() in the code, and have plans to audit our BUG_ON usage and remove it anywhere we can. Summary: - Various build fixes (USER_ACCESS=m and ADDR_TRANS turned off) - SPDX license tag cleanups (new tag Linux-OpenIB) - RoCE GID fixes related to default GIDs - Various fixes to: cxgb4, uverbs, cma, iwpm, rxe, hns (big batch), mlx4, mlx5, and hfi1 (medium batch)" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (52 commits) RDMA/cma: Do not query GID during QP state transition to RTR IB/mlx4: Fix integer overflow when calculating optimal MTT size IB/hfi1: Fix memory leak in exception path in get_irq_affinity() IB/{hfi1, rdmavt}: Fix memory leak in hfi1_alloc_devdata() upon failure IB/hfi1: Fix NULL pointer dereference when invalid num_vls is used IB/hfi1: Fix loss of BECN with AHG IB/hfi1 Use correct type for num_user_context IB/hfi1: Fix handling of FECN marked multicast packet IB/core: Make ib_mad_client_id atomic iw_cxgb4: Atomically flush per QP HW CQEs IB/uverbs: Fix kernel crash during MR deregistration flow IB/uverbs: Prevent reregistration of DM_MR to regular MR RDMA/mlx4: Add missed RSS hash inner header flag RDMA/hns: Fix a couple misspellings RDMA/hns: Submit bad wr RDMA/hns: Update assignment method for owner field of send wqe RDMA/hns: Adjust the order of cleanup hem table RDMA/hns: Only assign dqpn if IB_QP_PATH_DEST_QPN bit is set RDMA/hns: Remove some unnecessary attr_mask judgement RDMA/hns: Only assign mtu if IB_QP_PATH_MTU bit is set ...
