2016-11-17iw_cxgb4: invalidate the mr when posting a read_w_inv wrSteve Wise4-23/+24
Also, rearrange things a bit to have a common c4iw_invalidate_mr() function used everywhere that we need to invalidate.

2016-11-17iw_cxgb4: set *bad_wr for post_send/post_recv errorsSteve Wise1-0/+4
There are a few cases in c4iw_post_send() and c4iw_post_receive() where *bad_wr is not set when an error is returned. This can cause a crash if the application tries to use bad_wr. Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Doug Ledford <dledford@redhat.com>

2016-11-17IB/rxe: Clear queue buffer when modifying QP to resetYonatan Cohen3-0/+12
RXE resets the send-q only once in rxe_qp_init_req() when QP is created, but when the QP is reused after QP reset, the send-q holds previous garbage data. This garbage data wrongly fails CQEs that otherwise should have completed successfully.

2016-11-17IB/rxe: Fix handling of erroneous WRYonatan Cohen1-8/+13
To correctly handle a erroneous WR this fix does the following 1. Make sure the bad WQE causes a user completion event. 2. Call rxe_completer to handle the erred WQE. Before the fix, when rxe_requester found a bad WQE, it changed its status to IB_WC_LOC_PROT_ERR and exit with 0 for non RC QPs. If this was the 1st WQE then there would be no ACK to invoke the completer and this bad WQE would be stuck in the QP's send-q. On top of that the requester exiting with 0 caused rxe_do_task to endlessly invoke rxe_requester, resulting in a soft-lockup attached below. In case the WQE was not the 1st and rxe_completer did get a chance to handle the bad WQE, it did not cause a complete event since the WQE's IB_SEND_SIGNALED flag was not set. Setting WQE status to IB_SEND_SIGNALED is subject to IBA spec version 1.2.1, section 10.7.3.1 Signaled Completions. NMI watchdog: BUG: soft lockup - CPU#7 stuck for 22s!

2016-11-16IB/hfi1: Fix a potential memory leak in hfi1_create_ctxts()Jianxin Xiong1-6/+7
In the function hfi1_create_ctxts the array "dd->rcd" is allocated and then populated with allocated resources in a loop. Previously, if error happened during the loop, only resource allocated in the current iteration would be freed. The array itself would then be freed, leaving the resources that were allocated in previous iterations and referenced by the array elements in limbo. This patch makes sure all allocated resources are freed before freeing the array "dd->rcd". Also the resource allocation now takes account of the numa node the device is attached to.

This patch fixes an Oops on device unbind, when the device is used by a PSM user process. PSM processes access device resources which are freed on device removal. Similar protection exists in uverbs in ib_core for Verbs clients, but PSM doesn't use ib_uverbs hence a separate protection is required for PSM clients.

2016-11-16IB/rdmavt: rdmavt can handle non aligned page mapsDennis Dalessandro1-3/+0
The initial code for rdmavt carried with it a restriction that was a vestige from the qib driver, that to dma map a page it had to be less than a page size. This is not the case on modern hardware, both qib and hfi1 will be just fine with unaligned map requests. This fixes a 4.8 regression where by an IPoIB transfer of > PAGE_SIZE will hang because the dma map page call always fails. This was introduced after commit 5faba5469522 ("IB/ipoib: Report SG feature regardless of HW UD CSUM capability") added the capability to use SG by default. Rather than override this, the HW supports it, so allow SG.

2016-10-29x86/smpboot: Init apic mapping before usageThomas Gleixner1-1/+6
The recent changes, which forced the registration of the boot cpu on UP systems, which do not have ACPI tables, have been fixed for systems w/o local APIC, but left a wreckage for systems which have neither ACPI nor mptables, but the CPU has an APIC, e.g. virtualbox. The boot process crashes in prefill_possible_map() as it wants to register the boot cpu, which needs to access the local apic, but the local APIC is not yet mapped. There is no reason why init_apic_mapping() can't be invoked before prefill_possible_map(). So instead of playing another silly early mapping game, as the ACPI/mptables code does, we just move init_apic_mapping() before the call to prefill_possible_map(). In hindsight, I should have noticed that combination earlier. Sorry for the churn (also in stable)!
