2019-11-14qtnfmac: send EAPOL frames via control pathSergey Matyukevich
Send EAPOL frames via control path so they can be treated in a different way rather than normal data frames. In this case EAPOLs are sent with higher priority and with disabled aggregation and encryption. Besides, all devices benefit from sending EAPOL frames via high priority path, so move the functionality from chip specific to common code.

2019-11-14KVM: x86/mmu: Take slots_lock when using kvm_mmu_zap_all_fast()Sean Christopherson
Acquire the per-VM slots_lock when zapping all shadow pages as part of toggling nx_huge_pages. The fast zap algorithm relies on exclusivity (via slots_lock) to identify obsolete vs. valid shadow pages, because it uses a single bit for its generation number. Holding slots_lock also obviates the need to acquire a read lock on the VM's srcu. Failing to take slots_lock when toggling nx_huge_pages allows multiple instances of kvm_mmu_zap_all_fast() to run concurrently, as the other user, KVM_SET_USER_MEMORY_REGION, does not take the global kvm_lock. (kvm_mmu_zap_all_fast() does take kvm->mmu_lock, but it can be temporarily dropped by kvm_zap_obsolete_pages(), so it is not enough to enforce exclusivity). Concurrent fast zap instances causes obsolete shadow pages to be incorrectly identified as valid due to the single bit generation number wrapping, which results in stale shadow pages being left in KVM's MMU and leads to all sorts of undesirable behavior. The bug is easily confirmed by running with CONFIG_PROVE_LOCKING and toggling nx_huge_pages via its module param. Note, until commit 4ae5acbc4936 ("KVM: x86/mmu: Take slots_lock when using kvm_mmu_zap_all_fast()", 2019-11-13) the fast zap algorithm used an ulong-sized generation instead of relying on exclusivity for correctness, but all callers except the recently added set_nx_huge_pages() needed to hold slots_lock anyways. Therefore, this patch does not have to be backported to stable kernels. Given that toggling nx_huge_pages is by no means a fast path, force it to conform to the current approach instead of reintroducing the previous generation count.

2019-11-15kbuild: tell sparse about the $ARCHLuc Van Oostenryck
Sparse uses the same executable for all archs and uses flags like -m64, -mbig-endian or -D__arm__ for arch-specific parameters. But Sparse also uses value from the host machine used to build Sparse as default value for the target machine. This works, of course, well for native build but can create problems when cross-compiling, like defining both '__i386__' and '__arm__' when cross-compiling for arm on a x86-64 machine. Fix this by explicitely telling sparse the target architecture.

2019-11-14block, bfq: deschedule empty bfq_queues not referred by any processPaolo Valente
Since commit 3726112ec731 ("block, bfq: re-schedule empty queues if they deserve I/O plugging"), to prevent the service guarantees of a bfq_queue from being violated, the bfq_queue may be left busy, i.e., scheduled for service, even if empty (see comments in __bfq_bfqq_expire() for details). But, if no process will send requests to the bfq_queue any longer, then there is no point in keeping the bfq_queue scheduled for service. In addition, keeping the bfq_queue scheduled for service, but with no process reference any longer, may cause the bfq_queue to be freed when descheduled from service. But this is assumed to never happen, and causes a UAF if it happens. This, in turn, caused crashes [1, 2]. This commit fixes this issue by descheduling an empty bfq_queue when it remains with not process reference.

2019-11-13io_uring: ensure registered buffer import returns the IO lengthJens Axboe
A test case was reported where two linked reads with registered buffers failed the second link always. This is because we set the expected value of a request in req->result, and if we don't get this result, then we fail the dependent links. For some reason the registered buffer import returned -ERROR/0, while the normal import returns -ERROR/length. This broke linked commands with registered buffers.

In fact the "err" variable is only used to store integers (never irqreturn_t) so it should be declared as int. I removed the initialization because it's not required. Using a bogus initializer turns off GCC's uninitialized variable warnings. Secondly, there is a GCC warning about unused assignments and we would like to enable that feature eventually so we have been trying to remove these unnecessary initializers.

mlx5_device_disable_sriov() currently reads num_vfs from the PCI core. However when mlx5_device_disable_sriov() is executed, SR-IOV is already disabled at the PCI level. Due to this disable_hca() cleanup is not done during SR-IOV disable flow. mlx5_sriov_disable() pci_enable_sriov() mlx5_device_disable_sriov() <- num_vfs is zero here.

2019-11-13net/mlx5: Add new chain for netfilter flow table offloadPaul Blakey
Netfilter tables (nftables) implements a software datapath that comes after tc ingress datapath. The datapath supports offloading such rules via the flow table offload API. This API is currently only used by NFT and it doesn't provide the global priority in regards to tc offload, so we assume offloading such rules must come after tc. It does provide a flow table priority parameter, so we need to provide some supported priority range. For that, split fastpath prio to two, flow table offload and tc offload, with one dedicated priority chain for flow table offload. Next patch will re-use the multi chain API to access this chain by allowing access to this chain by the fdb_sub_namespace.

2019-11-13net/mlx5: Accumulate levels for chains prio namespacesPaul Blakey
Tc chains are implemented by creating a chained prio steering type, and inside it there is a namespace for each chain (FDB_TC_MAX_CHAINS). Each of those has a list of priorities. Currently, all namespaces in a prio start at the parent prio level. But since we can jump from chain (namespace) to another chain in the same prio, we need the levels for higher chains to be higher as well. So we created unused prios to account for levels in previous namespaces. Fix that by accumulating the namespaces levels if we are inside a chained type prio, and removing the unused prios.

2019-11-13drm/i915/tgl: MOCS table updateMatt Roper
The bspec was just updated with a minor correction to entry 61 (it shouldn't have had the SCF bit set). v2: - Add a MOCS_ENTRY_UNUSED() and use it to declare the explicitly-reserved MOCS entries. (Lucas) - Move the warning suppression from the Makefile to a #pragma that only affects the TGL table. (Lucas) v3: - Entries 16 and 17 are identical to ICL now, so no need to explicitly adjust them (or mess with compiler warning overrides).

2019-11-13Revert "drm/i915/ehl: Update MOCS table for EHL"Matt Roper
This reverts commit f4071997f1de016780ec6b79c63d90cd5886ee83. These extra EHL entries won't behave as expected without a bit more work on the kernel side so let's drop them until that kernel work has had a chance to land. Userspace trying to use these new entries won't get the advantage of the new functionality these entries are meant to provide, but at least it won't misbehave. When we do add these back in the future, we'll probably want to explicitly use separate tables for ICL and EHL so that userspace software that mistakenly uses these entries (which are undefined on ICL) sees the same behavior it sees with all the other undefined entries.

Change dev_up and dev_down functions of struct pn533_phy_ops to return int. This way the pn533 core can report errors in the phy layer to upper layers. The only user of this is currently uart.c and it is changed to report the error of a possibly failing call to serdev_device_open.
