9883764 | Maxim Levitsky | 27 August 2020, 16:27:18 UTC | SVM: nSVM: correctly restore GIF on vmexit from nesting after migration Currently code in svm_set_nested_state copies the current vmcb control area to L1 control area (hsave->control), under assumption that it mostly reflects the defaults that kvm choose, and later qemu overrides these defaults with L2 state using standard KVM interfaces, like KVM_SET_REGS. However nested GIF (which is AMD specific thing) is by default is true, and it is copied to hsave area as such. This alone is not a big deal since on VMexit, GIF is always set to false, regardless of what it was on VM entry. However in nested_svm_vmexit we were first were setting GIF to false, but then we overwrite the control fields with value from the hsave area. (including the nested GIF field itself if GIF virtualization is enabled). Now on normal vm entry this is not a problem, since GIF is usually false prior to normal vm entry, and this is the value that copied to hsave, and then restored, but this is not always the case when the nested state is loaded as explained above. To fix this issue, move svm_set_gif after we restore the L1 control state in nested_svm_vmexit, so that even with wrong GIF in the saved L1 control area, we still clear GIF as the spec says.

d877322 | Stafford Horne | 02 September 2020, 20:54:40 UTC | openrisc: Fix issue with get_user for 64-bit values A build failure was raised by kbuild with the following error. drivers/android/binder.c: Assembler messages: drivers/android/binder.c:3861: Error: unrecognized keyword/register name `l.lwz ?ap,4(r24)' drivers/android/binder.c:3866: Error: unrecognized keyword/register name `l.addi ?ap,r0,0' The issue is with 64-bit get_user() calls on openrisc. I traced this to a problem where in the internally in the get_user macros there is a cast to long __gu_val this causes GCC to think the get_user call is 32-bit. This binder code is really long and GCC allocates register r30, which triggers the issue. The 64-bit get_user asm tries to get the 64-bit pair register, which for r30 overflows the general register names and returns the dummy register ?ap. The fix here is to move the temporary variables into the asm macros. We use a 32-bit __gu_tmp for 32-bit and smaller macro and a 64-bit tmp in the 64-bit macro. The cast in the 64-bit macro has a trick of casting through __typeof__((x)-(x)) which avoids the below warning. This was barrowed from riscv. arch/openrisc/include/asm/uaccess.h:240:8: warning: cast to pointer from integer of different size I tested this in a small unit test to check reading between 64-bit and 32-bit pointers to 64-bit and 32-bit values in all combinations. Also I ran make C=1 to confirm no new sparse warnings came up. It all looks clean to me.

cc17b22 | Vitaly Kuznetsov | 08 September 2020, 13:53:50 UTC | x86/kvm: don't forget to ACK async PF IRQ Merge commit 26d05b368a5c0 ("Merge branch 'kvm-async-pf-int' into HEAD") tried to adapt the new interrupt based async PF mechanism to the newly introduced IDTENTRY magic but unfortunately it missed the fact that DEFINE_IDTENTRY_SYSVEC() doesn't call ack_APIC_irq() on its own and all DEFINE_IDTENTRY_SYSVEC() users have to call it manually. As the result all multi-CPU KVM guest hang on boot when KVM_FEATURE_ASYNC_PF_INT is present. The breakage went unnoticed because no KVM userspace (e.g. QEMU) currently set it (and thus async PF mechanism is currently disabled) but we're about to change that.

15e9e35 | Huacai Chen | 10 September 2020, 10:33:51 UTC | KVM: MIPS: Change the definition of kvm type MIPS defines two kvm types: #define KVM_VM_MIPS_TE 0 #define KVM_VM_MIPS_VZ 1 In Documentation/virt/kvm/api.rst it is said that "You probably want to use 0 as machine type", which implies that type 0 be the "automatic" or "default" type. And, in user-space libvirt use the null-machine (with type 0) to detect the kvm capability, which returns "KVM not supported" on a VZ platform. I try to fix it in QEMU but it is ugly: https://lists.nongnu.org/archive/html/qemu-devel/2020-08/msg05629.html And Thomas Huth suggests me to change the definition of kvm type: https://lists.nongnu.org/archive/html/qemu-devel/2020-09/msg03281.html So I define like this: #define KVM_VM_MIPS_AUTO 0 #define KVM_VM_MIPS_VZ 1 #define KVM_VM_MIPS_TE 2 Since VZ and TE cannot co-exists, using type 0 on a TE platform will still return success (so old user-space tools have no problems on new kernels); the advantage is that using type 0 on a VZ platform will not return failure. So, the only problem is "new user-space tools use type 2 on old kernels", but if we treat this as a kernel bug, we can backport this patch to old stable kernels.

f6f6195 | Lai Jiangshan | 02 September 2020, 13:54:21 UTC | kvm x86/mmu: use KVM_REQ_MMU_SYNC to sync when needed When kvm_mmu_get_page() gets a page with unsynced children, the spt pagetable is unsynchronized with the guest pagetable. But the guest might not issue a "flush" operation on it when the pagetable entry is changed from zero or other cases. The hypervisor has the responsibility to synchronize the pagetables. KVM behaved as above for many years, But commit 8c8560b83390 ("KVM: x86/mmu: Use KVM_REQ_TLB_FLUSH_CURRENT for MMU specific flushes") inadvertently included a line of code to change it without giving any reason in the changelog. It is clear that the commit's intention was to change KVM_REQ_TLB_FLUSH -> KVM_REQ_TLB_FLUSH_CURRENT, so we don't needlessly flush other contexts; however, one of the hunks changed a nearby KVM_REQ_MMU_SYNC instead. This patch changes it back.

43fea4e | Peter Shier | 20 August 2020, 23:05:45 UTC | KVM: nVMX: Update VMCS02 when L2 PAE PDPTE updates detected When L2 uses PAE, L0 intercepts of L2 writes to CR0/CR3/CR4 call load_pdptrs to read the possibly updated PDPTEs from the guest physical address referenced by CR3. It loads them into vcpu->arch.walk_mmu->pdptrs and sets VCPU_EXREG_PDPTR in vcpu->arch.regs_dirty. At the subsequent assumed reentry into L2, the mmu will call vmx_load_mmu_pgd which calls ept_load_pdptrs. ept_load_pdptrs sees VCPU_EXREG_PDPTR set in vcpu->arch.regs_dirty and loads VMCS02.GUEST_PDPTRn from vcpu->arch.walk_mmu->pdptrs[]. This all works if the L2 CRn write intercept always resumes L2. The resume path calls vmx_check_nested_events which checks for exceptions, MTF, and expired VMX preemption timers. If vmx_check_nested_events finds any of these conditions pending it will reflect the corresponding exit into L1. Live migration at this point would also cause a missed immediate reentry into L2. After L1 exits, vmx_vcpu_run calls vmx_register_cache_reset which clears VCPU_EXREG_PDPTR in vcpu->arch.regs_dirty. When L2 next resumes, ept_load_pdptrs finds VCPU_EXREG_PDPTR clear in vcpu->arch.regs_dirty and does not load VMCS02.GUEST_PDPTRn from vcpu->arch.walk_mmu->pdptrs[]. prepare_vmcs02 will then load VMCS02.GUEST_PDPTRn from vmcs12->pdptr0/1/2/3 which contain the stale values stored at last L2 exit. A repro of this bug showed L2 entering triple fault immediately due to the bad VMCS02.GUEST_PDPTRn values. When L2 is in PAE paging mode add a call to ept_load_pdptrs before leaving L2. This will update VMCS02.GUEST_PDPTRn if they are dirty in vcpu->arch.walk_mmu->pdptrs[]. Tested: kvm-unit-tests with new directed test: vmx_mtf_pdpte_test. Verified that test fails without the fix. Also ran Google internal VMM with an Ubuntu 16.04 4.4.0-83 guest running a custom hypervisor with a 32-bit Windows XP L2 guest using PAE. Prior to fix would repro readily. Ran 14 simultaneous L2s for 140 iterations with no failures.

0b089c1 | Sagi Grimberg | 04 September 2020, 19:50:39 UTC | IB/isert: Fix unaligned immediate-data handling Currently we allocate rx buffers in a single contiguous buffers for headers (iser and iscsi) and data trailer. This means that most likely the data starting offset is aligned to 76 bytes (size of both headers). This worked fine for years, but at some point this broke, resulting in data corruptions in isert when a command comes with immediate data and the underlying backend device assumes 512 bytes buffer alignment. We assume a hard-requirement for all direct I/O buffers to be 512 bytes aligned. To fix this, we should avoid passing unaligned buffers for I/O. Instead, we allocate our recv buffers with some extra space such that we can have the data portion align to 512 byte boundary. This also means that we cannot reference headers or data using structure but rather accessors (as they may move based on alignment). Also, get rid of the wrong __packed annotation from iser_rx_desc as this has only harmful effects (not aligned to anything). This affects the rx descriptors for iscsi login and data plane.

When entering controller reset, we transition the controller into NVME_CTRL_RESETTING, and then return BLK_STS_RESOURCE for non-mpath requests (have blk_noretry_request set). This is also the case for NVME_REQ_USER for the wrong reason. There shouldn't be any reason for us to reject this I/O in a controller reset. We do want to prevent passthru commands on the admin queue because we need the controller to fully initialize first before we let user passthru admin commands to be issued. In a non-mpath setup, this means that the requests will simply be requeued over and over forever not allowing the q_usage_counter to drop its final reference, causing controller reset to hang if running concurrently with heavy I/O.

While documentation is not strict about this corner case, most filesystem returns EOF on this case, like iomap filesystems. This patch consolidates the behavior for f2fs, by making it return EOF(0). it can be verified by a read loop on a file that does a partial read before EOF (A file that doesn't end at an aligned address). The following code fails on an unaligned file on f2fs, but not on btrfs, ext4, and xfs. while (done < total) { ssize_t delta = pread(fd, buf + done, total - done, off + done); if (!delta) break; ... } It is arguable whether filesystems should actually return EOF or -EINVAL, but since iomap filesystems support it, and so does the original DIO code, it seems reasonable to consolidate on that.

This results into mismatch between nm_i->available_nids and the sum of nm_i->free_nid_count of all NAT blocks scanned. And nm_i->available_nids will always be greater than the sum of free nids in all the blocks. Under this condition, if we use all the currently scanned free nids, then it will loop forever in f2fs_alloc_nid() as nm_i->available_nids is still not zero but nm_i->free_nid_count of that partially scanned NAT block is zero.

Since we check ->notif for null in order to determine if it's ok to install a filter, this means people won't be able to install a filter if the file allocation fails for some reason, even if they subsequently should be able to. To fix this, let's hoist this free+null into its own little helper and use it.

a566a90 | Tycho Andersen | 02 September 2020, 01:40:16 UTC | seccomp: don't leak memory when filter install races In seccomp_set_mode_filter() with TSYNC | NEW_LISTENER, we first initialize the listener fd, then check to see if we can actually use it later in seccomp_may_assign_mode(), which can fail if anyone else in our thread group has installed a filter and caused some divergence. If we can't, we partially clean up the newly allocated file: we put the fd, put the file, but don't actually clean up the *memory* that was allocated at filter->notif. Let's clean that up too. To accomplish this, let's hoist the actual "detach a notifier from a filter" code to its own helper out of seccomp_notify_release(), so that in case anyone adds stuff to init_listener(), they only have to add the cleanup code in one spot. This does a bit of extra locking and such on the failure path when the filter is not attached, but it's a slow failure path anyway.

b63de84 | James Smart | 28 August 2020, 19:01:50 UTC | nvme: Revert: Fix controller creation races with teardown flow The indicated patch introduced a barrier in the sysfs_delete attribute for the controller that rejects the request if the controller isn't created. "Created" is defined as at least 1 call to nvme_start_ctrl(). This is problematic in error-injection testing. If an error occurs on the initial attempt to create an association and the controller enters reconnect(s) attempts, the admin cannot delete the controller until either there is a successful association created or ctrl_loss_tmo times out. Where this issue is particularly hurtful is when the "admin" is the nvme-cli, it is performing a connection to a discovery controller, and it is initiated via auto-connect scripts. With the FC transport, if the first connection attempt fails, the controller enters a normal reconnect state but returns control to the cli thread that created the controller. In this scenario, the cli attempts to read the discovery log via ioctl, which fails, causing the cli to see it as an empty log and then proceeds to delete the discovery controller. The delete is rejected and the controller is left live. If the discovery controller reconnect then succeeds, there is no action to delete it, and it sits live doing nothing.

This broke the mechanism to immediately force a new CDCLK minimum, and lead to driver probe errors for display audio on GLK platform with 5.9-rc1 kernel. Fix the issue by moving intel_modeset_checks() call later. [vsyrjala: It also broke the ability of planes to bump up the cdclk and thus could lead to underruns when eg. flipping from 32bpp to 64bpp framebuffer. To be clear, we still compute the new cdclk correctly but fail to actually program it to the hardware due to intel_set_cdclk_{pre,post}_plane_update() not getting called on account of state->modeset==false.] Fixes: 4f0b4352bd26 ("drm/i915: Extract cdclk requirements checking to separate function") BugLink: https://github.com/thesofproject/linux/issues/2410 Signed-off-by: Kai Vehmanen <kai.vehmanen@linux.intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200901151036.1312357-1-kai.vehmanen@linux.intel.com (cherry picked from commit cf696856bc54a31f78e6538b84c8f7a006b6108b) Signed-off-by: Jani Nikula <jani.nikula@intel.com> | 08 September 2020, 11:38:46 UTC |
