Linus Torvalds	dbee3d0245	KVM: x86: VMX: fix build without hyper-v Commit `ceef7d10df` ("KVM: x86: VMX: hyper-v: Enlightened MSR-Bitmap support") broke the build with Hyper-V disabled, because it accesses ms_hyperv.nested_features without checking if that exists. This is the quick-and-hacky build fix. I suspect the proper fix is to replace the static_branch_unlikely(&enable_evmcs) tests with an inline helper function that also checks that CONFIG_HYPERV is enabled, since without that, enable_evmcs makes no sense. But I want a working build environment first and foremost, and I'm upset this slipped through in the first place. My primary build tests missed it because I tend to build with everything enabled, but it should have been caught in the kvm tree.

Yonghong Song	73df93c57c	tools/bpftool: fix a bug in bpftool perf Commit `b04df400c3` ("tools/bpftool: add perf subcommand") introduced bpftool subcommand perf to query bpf program kuprobe and tracepoint attachments. The perf subcommand will first test whether bpf subcommand BPF_TASK_FD_QUERY is supported in kernel or not. It does it by opening a file with argv[0] and feeds the file descriptor and current task pid to the kernel for querying. Such an approach won't work if the argv[0] cannot be opened successfully in the current directory. This is especially true when bpftool is accessible through PATH env variable. The error below reflects the open failure for file argv[0] at home directory. [yhs@localhost ~]$ which bpftool /usr/local/sbin/bpftool [yhs@localhost ~]$ bpftool perf Error: perf_query_support: No such file or directory To fix the issue, let us open root directory ("/") which exists in every linux system.

Simon Guo	f61e0d3cc4	KVM: PPC: Book3S PR: Fix failure status setting in tabort. emulation tabort. will perform transaction failure recording and the recording depends on TEXASR FS bit. Currently the TEXASR FS bit is retrieved after tabort., when the TEXASR FS bit is already been updated by tabort. itself. This patch corrects this behavior by retrieving TEXASR val before tabort. tabort. will not immediately leads to transaction failure handling in suspend state. So this patch also remove the mtspr on TEXASR/TFIAR registers to avoid TM bad thing exception.

Paul Mackerras	db96a04a86	KVM: PPC: Book3S PR: Enable use on POWER9 bare-metal hosts in HPT mode It turns out that PR KVM has no dependency on the format of HPTEs, because it uses functions pointed to by mmu_hash_ops which do all the formatting and interpretation of HPTEs.

Paul Mackerras	4f169d2118	KVM: PPC: Book3S PR: Don't let PAPR guest set MSR hypervisor bit PAPR guests run in supervisor mode and should not be able to set the MSR HV (hypervisor mode) bit or clear the ME (machine check enable) bit by mtmsrd or any other means. To enforce this, we force MSR_HV off and MSR_ME on in kvmppc_set_msr_pr. Without this, the guest can appear to be in hypervisor mode to itself and to userspace. This has been observed to cause a crash in QEMU when it tries to deliver a system reset interrupt to the guest. Signed-off-by: Paul Mackerras <paulus@ozlabs.org>	2018-06-13 09:45:28 +10:00
Paul Mackerras	a50623fb57	KVM: PPC: Book3S PR: Fix failure status setting in treclaim. emulation The treclaim. emulation needs to record failure status in the TEXASR register if the transaction had not previously failed. However, the current code first does kvmppc_save_tm_pr() (which does a treclaim. itself) and then checks the failure summary bit in TEXASR after that. Since treclaim. itself causes transaction failure, the FS bit is always set, so we were never updating TEXASR with the failure cause supplied by the guest as the RA parameter to the treclaim. instruction. This caused the tm-unavailable test in tools/testing/selftests/powerpc/tm to fail. To fix this, we need to read TEXASR before calling kvmppc_save_tm_pr(), and base the final value of TEXASR on that value. Fixes: `03c81682a9` ("KVM: PPC: Book3S PR: Add emulation for treclaim.")

Paul Mackerras	916ccadccd	KVM: PPC: Book3S PR: Fix MSR setting when delivering interrupts This makes sure that MSR "partial-function" bits are not transferred to SRR1 when delivering an interrupt. This was causing failures in guests running kernels that include commit `f3d96e698e` ("powerpc/mm: Overhaul handling of bad page faults", 2017-07-19), which added code to check bits of SRR1 on instruction storage interrupts (ISIs) that indicate a bad page fault. The symptom was that a guest user program that handled a signal and attempted to return from the signal handler would get a SIGBUS signal and die. The code that generated ISIs and some other interrupts would previously set bits in the guest MSR to indicate the interrupt status and then call kvmppc_book3s_queue_irqprio(). This technique no longer works now that kvmppc_inject_interrupt() is masking off those bits. Instead we make kvmppc_core_queue_data_storage() and kvmppc_core_queue_inst_storage() call kvmppc_inject_interrupt() directly, and make sure that all the places that generate ISIs or DSIs call kvmppc_core_queue_{data,inst}_storage instead of kvmppc_book3s_queue_irqprio().

Juergen Gross	57f230ab04	xen/netfront: raise max number of slots in xennet_get_responses() The max number of slots used in xennet_get_responses() is set to MAX_SKB_FRAGS + (rx->status <= RX_COPY_THRESHOLD). In old kernel-xen MAX_SKB_FRAGS was 18, while nowadays it is 17. This difference is resulting in frequent messages "too many slots" and a reduced network throughput for some workloads (factor 10 below that of a kernel-xen based guest). Replacing MAX_SKB_FRAGS by XEN_NETIF_NR_SLOTS_MIN for calculation of the max number of slots to use solves that problem (tests showed no more messages "too many slots" and throughput was as high as with the kernel-xen based guest system). Replace MAX_SKB_FRAGS-2 by XEN_NETIF_NR_SLOTS_MIN-1 in netfront_tx_slot_available() for making it clearer what is really being tested without actually modifying the tested value.

Vadim Lomovtsev	469998c861	net: thunderx: prevent concurrent data re-writing by nicvf_set_rx_mode For each network interface linux network stack issue ndo_set_rx_mode call in order to configure MAC address filters (e.g. for multicast filtering). Currently ThunderX NICVF driver has only one ordered workqueue to process such requests for all VFs. And because of that it is possible that subsequent call to ndo_set_rx_mode would corrupt data which is currently in use by nicvf_set_rx_mode_task.

Stephen Hemminger	8cde8f0c0c	hv_netvsc: drop common code until callback model fixed The callback model of handling network failover is not suitable in the current form. 1. It was merged without addressing all the review feedback. 2. It was merged without approval of any of the netvsc maintainers. 3. Design discussion on how to handle PV/VF fallback is still not complete. 4. IMHO the code model using callbacks is trying to make something common which isn't. Revert the netvsc specific changes for now. Does not impact ongoing development of failover model for virtio. Revisit this after a simpler library based failover kernel routines are extracted.
