[PATCH v2] RDMA/rxe: Set wqe->status correctly if an unexpected response is received

by Bart Van Assche

Every function that returns COMPST_ERROR must set wqe->status to another value than IB_WC_SUCCESS before returning COMPST_ERROR. Fix the only code path for which this is not yet the case.

It turns out that this empty "subvol=" is actually an application bug, but it was causing the application to fail, so it's an ABI break if you squint. The generic parsing code we use for mount options (match_token()) doesn't match an empty string as "%s". Previously, setup_root_args() removed the "subvol=" string, but the mount path was cleaned up to not need that. Add a dummy Opt_subvol_empty to fix this. The simple workaround is to use / or . for the value of 'subvol=' .

[PATCH 1/3] binfmt_elf: Respect error return from `regset->active'

by Maciej W. Rozycki

The regset API documented in <linux/regset.h> defines -ENODEV as the result of the `->active' handler to be used where the feature requested is not available on the hardware found. However code handling core file note generation in `fill_thread_core_info' interpretes any non-zero result from the `->active' handler as the regset requested being active. Consequently processing continues (and hopefully gracefully fails later on) rather than being abandoned right away for the regset requested. Fix the problem then by making the code proceed only if a positive result is returned from the `->active' handler. Cc: stable(a)vger.kernel.org # 2.6.25+ Fixes: 4206d3aa1978 ("elf core dump: notes user_regset") Signed-off-by: Maciej W. Rozycki <macro(a)mips.com> --- Hi, Overall we could also use the count returned by ->active to limit the size of data requested, i.e. something along the lines of: ssize_t size; if (regset->active) size = regset->active(t->task, regset); else size = regset_size(t->task, regset); if (size > 0) { ... however that would be an optimisation that belongs to a separate change, which (due to the need to unload stuff I have in progress already) I am not going to make at this point. Perhaps someone else would be willing to pick up the idea. Anyway, please apply.

[PATCH 1/5] xhci: Fix perceived dead host due to runtime suspend race with event handler

by Mathias Nyman

Don't rely on event interrupt (EINT) bit alone to detect pending port change in resume. If no change event is detected the host may be suspended again, oterwise roothubs are resumed. There is a lag in xHC setting EINT. If we don't notice the pending change in resume, and the controller is runtime suspeded again, it causes the event handler to assume host is dead as it will fail to read xHC registers once PCI puts the controller to D3 state. [ 268.520969] xhci_hcd: xhci_resume: starting port polling. [ 268.520985] xhci_hcd: xhci_hub_status_data: stopping port polling. [ 268.521030] xhci_hcd: xhci_suspend: stopping port polling.

This is to provide an adjustment for new forms of PMEM and other DIMM memory that might require alignment restrictions other than scanning the global address table for the required minimum alignment. The value set will be further adjusted by both the GAM range table scan as well as restrictions imposed by set_memory_block_size_order().

This accommodates changes in the Intel BIOS, and therefore UV BIOS, which now can align boundaries different than the previous UV standard of 2GB. It also flags any UV Global Address boundaries from BIOS that cause a change in the mem block size (boundary). The current boundary of 2GB has been used on UV since the first system release in 2009 with Linux 2.6 and has worked fine. But the new NVDIMM persistent memory modules (PMEM), along with the Intel BIOS changes to support these modules caused the memory block size boundary to be set to a lower limit. Intel only guarantees that this minimum boundary at 64MB though the current Linux limit is 128MB. Note that the default remains 2GB if no changes occur.
