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.

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 |

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.

KVM: arm64: Do not try to map PUDs when they are folded into PMD
For the obscure cases where PMD and PUD are the same size
(64kB pages with 42bit VA, for example, which results in only
two levels of page tables), we can't map anything as a PUD,
because there is... erm... no PUD to speak of. Everything is
either a PMD or a PTE.
So let's only try and map a PUD when its size is different from
that of a PMD.

KVM: arm64: Only reschedule if MMU_NOTIFIER_RANGE_BLOCKABLE is not set
When an MMU notifier call results in unmapping a range that spans multiple
PGDs, we end up calling into cond_resched_lock() when crossing a PGD boundary,
since this avoids running into RCU stalls during VM teardown. Unfortunately,
if the VM is destroyed as a result of OOM, then blocking is not permitted
and the call to the scheduler triggers the following BUG():

KVM: Pass MMU notifier range flags to kvm_unmap_hva_range()
The 'flags' field of 'struct mmu_notifier_range' is used to indicate
whether invalidate_range_{start,end}() are permitted to block. In the
case of kvm_mmu_notifier_invalidate_range_start(), this field is not
forwarded on to the architecture-specific implementation of
kvm_unmap_hva_range() and therefore the backend cannot sensibly decide
whether or not to block.
Add an extra 'flags' parameter to kvm_unmap_hva_range() so that
architectures are aware as to whether or not they are permitted to block.

arm64/x86: KVM: Introduce steal-time cap
arm64 requires a vcpu fd (KVM_HAS_DEVICE_ATTR vcpu ioctl) to probe support for steal-time. However this is unnecessary, as only a KVM fd is required, and it complicates userspace (userspace may prefer delaying vcpu creation until after feature probing). Introduce a cap that can be checked instead. While x86 can already probe steal-time support with a kvm fd (KVM_GET_SUPPORTED_CPUID), we add the cap there too for consistency.

selftests: kvm: Use a shorter encoding to clear RAX
If debug_regs.c is built with newer binutils, the resulting binary is "optimized"
by the assembler:
asm volatile("ss_start: "
"xor %%rax,%%rax\n\t"
"cpuid\n\t"
"movl $0x1a0,%%ecx\n\t"
"rdmsr\n\t"
: : : "rax", "ecx");
is translated to :
000000000040194e <ss_start>:
40194e: 31 c0 xor %eax,%eax <----- rax->eax?
401950: 0f a2 cpuid
401952: b9 a0 01 00 00 mov $0x1a0,%ecx
401957: 0f 32 rdmsr
As you can see rax is replaced with eax in target binary code.
This causes a difference is the length of xor instruction (2 Byte vs 3 Byte),
and makes the hard-coded instruction length check fail:
/* Instruction lengths starting at ss_start */
int ss_size[4] = {
3, /* xor */ <-------- 2 or 3?
2, /* cpuid */
5, /* mov */
2, /* rdmsr */
};
Encode the shorter version directly and, while at it, fix the "clobbers"
of the asm.

A RISC-V Fix for 5.9
I collected a single fix during the merge window: we managed to break the early trap setup on !MMU, this patch fixes it. The power keeps going on here so I haven't have a chance to give this the testing I usually would, but I don't have a Kendryte anyway so I doubt I'd pick up anything subtle even if I was to test. The patch seems pretty safe and it's still early, so I don't see any reason to let it sit around. It's fairly late so if it misses the merge window that's not a big deal. I'll definately have stuff for next week, so I'll just start from whenever this lands. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEKzw3R0RoQ7JKlDp6LhMZ81+7GIkFAl84Y58THHBhbG1lckBk YWJiZWx0LmNvbQAKCRAuExnzX7sYiVs8D/9blga759Z5w71l3wQ7htZnYuw2bJPw 9vp+TgRBsdBFpVvVR/81E3deLnEk0WaYt+kg3b1SJRcYCeXpfOGofrLx/u1/pFM4 Tpl2CTQOTumPBYEQLzUEIBxTNbusHDR4s0H3FVzJ6mwhGQk8YAaeD0Vs7CjxASoq ZI4JrHBo042vFV85gLqVV9q2oGjRC/kqqep2Utq7HRL2hov/A9IU1A5V7FylPn9+ CysVEicue3IalHX3ZuTNctzHGnrnyO33gnbihrxh1c7MvVQdeI4BAFpwPR/hTMwa cg3DFnQQ5TYT8BkYssNrikgkzGuPzuYMpntP9CrR4zpWu8hEZJv4h0c+hu3OcLoJ zDwAuQu9m/iZ98LPev1IMXrComlUb5jUJgRR9HAazUQhsVlj1jXPmFiyHtKsFJ3m zfGyrUklTAm2XRhfbM3kiW9c+qrnc/L9qZaLp4JxgPLj8wBYJBOH/XpaasLbR+Tz 8XNtJ8yfCOHY8srQI752v1vFcF7V4mFKPUu8XJZuZbs/IX+8dH0b5ki6vdPZ5oiS sOlDnjTLY3s7uM8Lh2KE/DKMKyJ160F80pzr6QfD45h5qINOZp+9TntA+KE2hvZ8 1yJd0R27Pc6HOwgv95q9W93St2pA/oC24kKr5OLHjjf5I3Q4vZiLet3sIw1SFViF u/+W+oKP1Lo6qQ== =+8KT -----END PGP SIGNATURE----- Merge tag 'riscv-for-linus-5.9-mw1' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux Pull RISC-V fix from Palmer Dabbelt: "I collected a single fix during the merge window: we managed to break the early trap setup on !MMU, this fixes it" * tag 'riscv-for-linus-5.9-mw1' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: riscv: Setup exception vector for nommu platform |

io_uring: short circuit -EAGAIN for blocking read attempt
One case was missed in the short IO retry handling, and that's hitting
-EAGAIN on a blocking attempt read (eg from io-wq context). This is a
problem on sockets that are marked as non-blocking when created, they
don't carry any REQ_F_NOWAIT information to help us terminate them
instead of perpetually retrying.

io_uring: sanitize double poll handling
There's a bit of confusion on the matching pairs of poll vs double poll,
depending on if the request is a pure poll (IORING_OP_POLL_ADD) or
poll driven retry.
Add io_poll_get_double() that returns the double poll waitqueue, if any,
and io_poll_get_single() that returns the original poll waitqueue. With
that, remove the argument to io_poll_remove_double().
Finally ensure that wait->private is cleared once the double poll handler
has run, so that remove knows it's already been seen.

perf tools changes for v5.9: 2nd batch
Fixes:
- Fixes for 'perf bench numa'.
- Always memset source before memcpy in 'perf bench mem'.
- Quote CC and CXX for their arguments to fix build in environments using
those variables to pass more than just the compiler names.
- Fix module symbol processing, addressing regression detected via "perf test".
- Allow multiple probes in record+script_probe_vfs_getname.sh 'perf test' entry.
Improvements:
- Add script to autogenerate socket family name id->string table from copy of
kernel header, used so far in 'perf trace'.
- 'perf ftrace' improvements to provide similar options for this utility so
that one can go from 'perf record', 'perf trace', etc to 'perf ftrace' just
by changing the name of the subcommand.
- Prefer new "sched:sched_waking" trace event when it exists in 'perf sched'
post processing.
- Update POWER9 metrics to utilize other metrics.
- Fall back to querying debuginfod if debuginfo not found locally.
Miscellaneous:
- Sync various kvm headers with kernel sources.
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
fedora:rawhide with python3 and gcc 10.1.1-2 is failing (10.1.1-1 on fedora:32
works), fixes will be provided soon.
clearlinux:latest is failing on libbpf, there is a fix already in the bpf tree.

iomap: constify ioreadX() iomem argument (as in generic implementation)
Patch series "iomap: Constify ioreadX() iomem argument", v3. The ioread8/16/32() and others have inconsistent interface among the architectures: some taking address as const, some not. It seems there is nothing really stopping all of them to take pointer to const. This patch (of 4): The ioreadX() and ioreadX_rep() helpers have inconsistent interface. On some architectures void *__iomem address argument is a pointer to const, on some not. Implementations of ioreadX() do not modify the memory under the address so they can be converted to a "const" version for const-safety and consistency among architectures.

80 is above array bounds of 'char[26]' [-Warray-bounds]
: "0" (__dest), "1" (__src), "r" (__src+__n)
~~~~~^~~~
In general, strncpy() should behave like below.
char dest[10];
char *src = "12345";
strncpy(dest, src, 10);
// dest = {'1', '2', '3', '4', '5',
'\0','\0','\0','\0','\0'}
But, current SH strnpy() has 2 issues.
1st is it will access to out-of-memory (= src + 10).
2nd is it needs big fixup for it, and maintenance __asm__
code is difficult.
To solve these issues, this patch simply uses generic strncpy()
instead of architecture specific one.
