KVM: svm: avic: Add support for dynamic setup/teardown of virtual APIC backing page
Re-factor avic_init_access_page() to avic_update_access_page() since activate/deactivate AVIC requires setting/unsetting the memory region used for virtual APIC backing page (APIC_ACCESS_PAGE_PRIVATE_MEMSLOT).

kvm: x86: Add support for dynamic APICv activation
Certain runtime conditions require APICv to be temporary deactivated during runtime. The current implementation only support run-time deactivation of APICv when Hyper-V SynIC is enabled, which is not temporary. In addition, for AMD, when APICv is (de)activated at runtime, all vcpus in the VM have to operate in the same mode. Thus the requesting vcpu must notify the others. So, introduce the following: * A new KVM_REQ_APICV_UPDATE request bit * Interfaces to request all vcpus to update APICv status * A new interface to update APICV-related parameters for each vcpu Signed-off-by: Suravee Suthikulpanit <suravee.suthikulpanit@amd.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> |

kvm: x86: Introduce APICv inhibit reason bits
There are several reasons in which a VM needs to deactivate APICv e.g. disable APICv via parameter during module loading, or when enable Hyper-V SynIC support. Additional inhibit reasons will be introduced later on when dynamic APICv is supported, Introduce KVM APICv inhibit reason bits along with a new variable, apicv_inhibit_reasons, to help keep track of APICv state for each VM, Initially, the APICV_INHIBIT_REASON_DISABLE bit is used to indicate the case where APICv is disabled during KVM module load. (e.g. insmod kvm_amd avic=0 or insmod kvm_intel enable_apicv=0).

ARM: Cleanups and corner case fixes
PPC: Bugfixes x86: * Support for mapping DAX areas with large nested page table entries. * Cleanups and bugfixes here too. A particularly important one is a fix for FPU load when the thread has TIF_NEED_FPU_LOAD. There is also a race condition which could be used in guest userspace to exploit the guest kernel, for which the embargo expired today. * Fast path for IPI delivery vmexits, shaving about 200 clock cycles from IPI latency. * Protect against "Spectre-v1/L1TF" (bring data in the cache via speculative out of bound accesses, use L1TF on the sibling hyperthread to read it), which unfortunately is an even bigger whack-a-mole game than SpectreV1. Sean continues his mission to rewrite KVM. In addition to a sizable number of x86 patches, this time he contributed a pretty large refactoring of vCPU creation that affects all architectures but should not have any visible effect. s390 will come next week together with some more x86 patches. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQEcBAABAgAGBQJeMxtCAAoJEL/70l94x66DQxIIAJv9hMmXLQHGFnUMskjGErR6 DCLSC0YRdRMwE50CerblyJtGsMwGsPyHZwvZxoAceKJ9w0Yay9cyaoJ87ItBgHoY ce0HrqIUYqRSJ/F8WH2lSzkzMBr839rcmqw8p1tt4D5DIsYnxHGWwRaaP+5M/1KQ YKFu3Hea4L00U339iIuDkuA+xgz92LIbsn38svv5fxHhPAyWza0rDEYHNgzMKuoF IakLf5+RrBFAh6ZuhYWQQ44uxjb+uQa9pVmcqYzzTd5t1g4PV5uXtlJKesHoAvik Eba8IEUJn+HgQJjhp3YxQYuLeWOwRF3bwOiZ578MlJ4OPfYXMtbdlqCQANHOcGk= =H/q1 -----END PGP SIGNATURE----- Merge tag 'kvm-5.6-1' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull KVM updates from Paolo Bonzini: "This is the first batch of KVM changes.

MPX requires recompiling applications, which requires compiler support.
Unfortunately, GCC 9.1 is expected to be be released without support for MPX. This means that there was only a relatively small window where folks could have ever used MPX. It failed to gain wide adoption in the industry, and Linux was the only mainstream OS to ever support it widely. Support for the feature may also disappear on future processors. This set completes the process that we started during the 5.4 merge window. -----BEGIN PGP SIGNATURE----- iQIcBAABCAAGBQJeK1/pAAoJEGg1lTBwyZKwgC8QAIiVn1d7A9Uj/WpnpgfCChCZ 9XiV6Ak999qD9fbAcrgNfPjieaD4mtokocSRVJuRgJu5iLnIJCINlozLPe4yVl7P 7zebnxkLq0CIA8d56bEUoFlC0J+oWYlDVQePZzNQsSk5KHVGXVLpF6U4vDVzZeQy cprgvdeY+ehB7G6IIo0MWTg5ylKYAsOAyVvK8NIGpKY2k6/YqCnsptnsVE7bvlHy TrEOiUWLv+hh0bMkZdP1PwKQKEuMO/IZly0HtviFbMN7T4TB1spfg7ELoBucEq3T s4EVbYRe+nIE4tuEAveaX3CgxJek8cY5MlticskdaKSEACBwabdOF55qsZy0u+WA PYC4iUIXfbOH8OgieKWtGX4IuSkRYdQ2nP4BOpe4ZX4+zvU7zOCIyVSKRrwkX8cc ADtWI5FAtB36KCgUuWnHGHNZpOxPTbTLBuBataFY4Q2uBNJEBJpscZ5H9ObtyGFU ZjlzqFnM0nFNDKEI1EEtv9jLzgZTU1RQ46s7EFeSeEQ2/s9wJ3+s5sBlVbljsmus o658bLOEaRWC/aF15dgmEXW9GAO6uifNdmbzGnRn7oEMYyFQPTWbZvi1zGz58QaG Y6WTtigVtsSrHS4wpYd+p+n1W06VnB6J3BpBM4G1VQv1Vm0dNd1tUOfkqOzPjg7c 33Itmsz2LaW1mb67GlgZ =g4cC -----END PGP SIGNATURE----- Merge tag 'mpx-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/daveh/x86-mpx Pull x86 MPX removal from Dave Hansen: "MPX requires recompiling applications, which requires compiler support.

f2fs-for-5.6
In this series, we've implemented transparent compression experimentally. It supports LZO and LZ4, but will add more later as we investigate in the field more. At this point, the feature doesn't expose compressed space to user directly in order to guarantee potential data updates later to the space. Instead, the main goal is to reduce data writes to flash disk as much as possible, resulting in extending disk life time as well as relaxing IO congestion. Alternatively, we're also considering to add ioctl() to reclaim compressed space and show it to user after putting the immutable bit. Enhancement: - add compression support - avoid unnecessary locks in quota ops - harden power-cut scenario for zoned block devices - use private bio_set to avoid IO congestion - replace GC mutex with rwsem to serialize callers Bug fix: - fix dentry consistency and memory corruption in rename()'s error case - fix wrong swap extent reports - fix casefolding bugs - change lock coverage to avoid deadlock - avoid GFP_KERNEL under f2fs_lock_op And, we've cleaned up sysfs entries to prepare no debugfs. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAl4zInwACgkQQBSofoJI UNL4Tg/+JBbVEFa3IUBGMdbjfgd/g0Jye++iMAYYGRWT6Ll/IGcHRV9NunITjgWU mBZqdhI28kXeiGCcewB1ZvivjLx22X4n6yevHk2B5A6PNe9IDCHi0HOAhJJHkjPH ecv2L+vX3Oj4y0+H7JNz9Fo3OIPJvMPtCQWlg1z+VQyhB85zNP7fZlvvIY4tG8yw ERo0YNotLqwcF1BxCwNbAhV3aJGDxar+MI//yNzpiwDX7IptVpqestfcoIYc9kKL 4kSWRyEIGwcuIeyoM6aofGS9t4Z/Oe/gdqcxNr6l5n0Q/tMTpb4b/fJFGNr6RRx9 X9NQo8flkQb2DEIOP0DVpO2aPebzsVtzg3LZUOLA83+wCHfwINtHai2Dy2zDJ2my BrVdou8fe2oxoaYihJg/Tz9cd0nA/6mZArtpYvDImAmX/xuGOvVk9zZkXNwc9nVX EyVzy0vW4lA6gAIJ95aG6DDhJcAtVoy0MhBRWG92Pufxhn9aW24AV63ChWUf9DRx /3RqpMAuQ3UC2gOxXKKnr54lsdhUIMn/y9sjROkVvQ1BvgRVxO8I4GFvMHMKv9pR 9KXiVRdzyYERyoL4+MF7A2zTnw+RHL4RVILa85p2ALGy2jQ1UuNUQi0BN9x2u1v8 S1ifNNX8SwOP+83ImFJhhn3HybpFQ45aLO3F7ZjKBQAnufJu+xw= =zeoY -----END PGP SIGNATURE----- Merge tag 'f2fs-for-5.6' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this series, we've implemented transparent compression experimentally.

Merge branch 'cve-2019-3016' into kvm-next-5.6
From Boris Ostrovsky: The KVM hypervisor may provide a guest with ability to defer remote TLB flush when the remote VCPU is not running. When this feature is used, the TLB flush will happen only when the remote VPCU is scheduled to run again. This will avoid unnecessary (and expensive) IPIs. Under certain circumstances, when a guest initiates such deferred action, the hypervisor may miss the request. It is also possible that the guest may mistakenly assume that it has already marked remote VCPU as needing a flush when in fact that request had already been processed by the hypervisor. In both cases this will result in an invalid translation being present in a vCPU, potentially allowing accesses to memory locations in that guest's address space that should not be accessible. Note that only intra-guest memory is vulnerable. The five patches address both of these problems: 1. The first patch makes sure the hypervisor doesn't accidentally clear a guest's remote flush request 2. The rest of the patches prevent the race between hypervisor acknowledging a remote flush request and guest issuing a new one. Conflicts: arch/x86/kvm/x86.c [move from kvm_arch_vcpu_free to kvm_arch_vcpu_destroy] |

x86/KVM: Make sure KVM_VCPU_FLUSH_TLB flag is not missed
There is a potential race in record_steal_time() between setting host-local vcpu->arch.st.steal.preempted to zero (i.e. clearing KVM_VCPU_PREEMPTED) and propagating this value to the guest with kvm_write_guest_cached(). Between those two events the guest may still see KVM_VCPU_PREEMPTED in its copy of kvm_steal_time, set KVM_VCPU_FLUSH_TLB and assume that hypervisor will do the right thing. Which it won't. Instad of copying, we should map kvm_steal_time and that will guarantee atomicity of accesses to @preempted. This is part of CVE-2019-3016.

y2038: sparc: remove use of struct timex
'struct timex' is one of the last users of 'struct timeval' and is only referenced in one place in the kernel any more, to convert the user space timex into the kernel-internal version on sparc64, with a different tv_usec member type. As a preparation for hiding the time_t definition and everything using that in the kernel, change the implementation once more to only convert the timeval member, and then enclose the struct definition in an #ifdef.

mptcp: Fix undefined mptcp_handle_ipv6_mapped for modular IPV6
If CONFIG_MPTCP=y, CONFIG_MPTCP_IPV6=n, and CONFIG_IPV6=m:
ERROR: "mptcp_handle_ipv6_mapped" [net/ipv6/ipv6.ko] undefined!
This does not happen if CONFIG_MPTCP_IPV6=y, as CONFIG_MPTCP_IPV6
selects CONFIG_IPV6, and thus forces CONFIG_IPV6 builtin.
As exporting a symbol for an empty function would be a bit wasteful, fix
this by providing a dummy version of mptcp_handle_ipv6_mapped() for the
CONFIG_MPTCP_IPV6=n case.
Rename mptcp_handle_ipv6_mapped() to mptcpv6_handle_mapped(), to make it
clear this is a pure-IPV6 function, just like mptcpv6_init().

mptcp: MPTCP_HMAC_TEST should depend on MPTCP
As the MPTCP HMAC test is integrated into the MPTCP code, it can be
built only when MPTCP is enabled. Hence when MPTCP is disabled, asking
the user if the test code should be enabled is futile.
Wrap the whole block of MPTCP-specific config options inside a check for
MPTCP. While at it, drop the "default n" for MPTCP_HMAC_TEST, as that
is the default anyway.

This syscall allows for the retrieval of file descriptors of a process based on its pidfd. A task needs to have ptrace_may_access() permissions with PTRACE_MODE_ATTACH_REALCREDS (suggested by Oleg and Andy) on the target. One of the main use-cases is in combination with seccomp's user notification feature. As a reminder, seccomp's user notification feature was made available in v5.0. It allows a task to retrieve a file descriptor for its seccomp filter. The file descriptor is usually handed of to a more privileged supervising process. The supervisor can then listen for syscall events caught by the seccomp filter of the supervisee and perform actions in lieu of the supervisee, usually emulating syscalls. pidfd_getfd() is needed to expand its uses. There are currently two major users that wait on pidfd_getfd() and one future user: - Netflix, Sargun said, is working on a service mesh where users should be able to connect to a dns-based VIP. When a user connects to e.g. 1.2.3.4:80 that runs e.g. service "foo" they will be redirected to an envoy process. This service mesh uses seccomp user notifications and pidfd to intercept all connect calls and instead of connecting them to 1.2.3.4:80 connects them to e.g. 127.0.0.1:8080. - LXD uses the seccomp notifier heavily to intercept and emulate mknod() and mount() syscalls for unprivileged containers/processes. With pidfd_getfd() more uses-cases e.g. bridging socket connections will be possible. - The patchset has also seen some interest from the browser corner. Right now, Firefox is using a SECCOMP_RET_TRAP sandbox managed by a broker process. In the future glibc will start blocking all signals during dlopen() rendering this type of sandbox impossible. Hence, in the future Firefox will switch to a seccomp-user-nofication based sandbox which also makes use of file descriptor retrieval. The thread for this can be found at https://sourceware.org/ml/libc-alpha/2019-12/msg00079.html With pidfd_getfd() it is e.g. possible to bridge socket connections for the supervisee (binding to a privileged port) and taking actions on file descriptors on behalf of the supervisee in general. Sargun's first version was using an ioctl on pidfds but various people pushed for it to be a proper syscall which he duely implemented as well over various review cycles. Selftests are of course included. I've also added instructions how to deal with merge conflicts below. There's also a small fix coming from the kernel mentee project to correctly annotate struct sighand_struct with __rcu to fix various sparse warnings. We've received a few more such fixes and even though they are mostly trivial I've decided to postpone them until after -rc1 since they came in rather late and I don't want to risk introducing build warnings. Finally, there's a new prctl() command PR_{G,S}ET_IO_FLUSHER which is needed to avoid allocation recursions triggerable by storage drivers that have userspace parts that run in the IO path (e.g. dm-multipath, iscsi, etc). These allocation recursions deadlock the device. The new prctl() allows such privileged userspace components to avoid allocation recursions by setting the PF_MEMALLOC_NOIO and PF_LESS_THROTTLE flags. The patch carries the necessary acks from the relevant maintainers and is routed here as part of prctl() thread-management." * tag 'threads-v5.6' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: prctl: PR_{G,S}ET_IO_FLUSHER to support controlling memory reclaim sched.h: Annotate sighand_struct with __rcu test: Add test for pidfd getfd arch: wire up pidfd_getfd syscall pid: Implement pidfd_getfd syscall vfs, fdtable: Add fget_task helper |

- Fix DM core's potential for q->make_request_fn NULL pointer in the
unlikely case that a DM device is created without a DM table and then accessed due to upper-layer userspace code or user error. - Fix DM thin-provisioning's metadata_pre_commit_callback to not use memory after it is free'd. Also refactor code to disallow changing the thin-pool's data device once in use -- doing so guarantees smae lifetime of pool's data device relative to the pool metadata. - Fix DM space maps used by DM thinp and DM cache to avoid reuse of a already used block. This race was identified with extremely heavy snapshot use in the context of DM thin provisioning. - Fix DM raid's table status relative to an active rebuild. - Fix DM crypt to use GFP_NOIO rather than GFP_NOFS in call to skcipher_request_alloc(). Also fix benbi IV constructor crash if used in authenticated mode. - Add DM crypt support for Elephant diffuser to allow for Bitlocker compatibility. - Fix DM verity target to not prefetch hash blocks for data that has already been verified. - Fix DM writecache's incorrect flush sequence during commit when in SSD mode. - Improve DM writecache's sequential write performance on SSDs. - Add DM zoned target support for zone sizes smaller than 128MiB. - Add DM multipath 'queue_if_no_path_timeout_secs' module param to allow timeout if path isn't reinstated. This allows users a kernel safety-net against IO hanging indefinitely, due to no active paths, that has historically only been provided by multipathd userspace. - Various DM code cleanups to use true/false rather than 1/0, a variable rename in dm-dust, and fix for a math error in comment for DM thin metadata's ondisk format. -----BEGIN PGP SIGNATURE----- iQFHBAABCAAxFiEEJfWUX4UqZ4x1O2wixSPxCi2dA1oFAl4xvEITHHNuaXR6ZXJA cmVkaGF0LmNvbQAKCRDFI/EKLZ0DWipYCAC+sX8q/XBDRi4WDCTvCRCcBfz9g9ZO oygimV64oYf08JiDL54Z29T0EjwGR6DcZB0nEyjhl2/lU4bPwd4kLc/VHwjf44ay oUJWZxp8Az7pIWjQQ5oC09it8gLmDpBdq2Z146tEDgYrERnH8BgDObYm3ihXwi9f zMoET8rIzNltMUo6jIumjzxPcLbBsRTnC35mE//PZkMiUUI3ucNWuOhD/ICDe/Tu VQ9rNtJx01xs07bFKT4OYR2Oc7xrtWEOMDKeSFz16j8t28wywLFz3EPXRG7tKM3l 6CKBFdRqPSL6v2Mr1QD8YwJJCPLsCoOQ14aKn2sDPG8EgQMnh7R2g6OT =mfnM -----END PGP SIGNATURE----- Merge tag 'for-5.6/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper updates from Mike Snitzer: - Fix DM core's potential for q->make_request_fn NULL pointer in the unlikely case that a DM device is created without a DM table and then accessed due to upper-layer userspace code or user error. - Fix DM thin-provisioning's metadata_pre_commit_callback to not use memory after it is free'd.

y2038: core, driver and file system changes
These are updates to device drivers and file systems that for some reason or another were not included in the kernel in the previous y2038 series. I've gone through all users of time_t again to make sure the kernel is in a long-term maintainable state, replacing all remaining references to time_t with safe alternatives. Some related parts of the series were picked up into the nfsd, xfs, alsa and v4l2 trees. A final set of patches in linux-mm removes the now unused time_t/timeval/timespec types and helper functions after all five branches are merged for linux-5.6, ensuring that no new users get merged. As a result, linux-5.6, or my backport of the patches to 5.4 [1], should be the first release that can serve as a base for a 32-bit system designed to run beyond year 2038, with a few remaining caveats: - All user space must be compiled with a 64-bit time_t, which will be supported in the coming musl-1.2 and glibc-2.32 releases, along with installed kernel headers from linux-5.6 or higher. - Applications that use the system call interfaces directly need to be ported to use the time64 syscalls added in linux-5.1 in place of the existing system calls. This impacts most users of futex() and seccomp() as well as programming languages that have their own runtime environment not based on libc. - Applications that use a private copy of kernel uapi header files or their contents may need to update to the linux-5.6 version, in particular for sound/asound.h, xfs/xfs_fs.h, linux/input.h, linux/elfcore.h, linux/sockios.h, linux/timex.h and linux/can/bcm.h. - A few remaining interfaces cannot be changed to pass a 64-bit time_t in a compatible way, so they must be configured to use CLOCK_MONOTONIC times or (with a y2106 problem) unsigned 32-bit timestamps. Most importantly this impacts all users of 'struct input_event'. - All y2038 problems that are present on 64-bit machines also apply to 32-bit machines. In particular this affects file systems with on-disk timestamps using signed 32-bit seconds: ext4 with ext3-style small inodes, ext2, xfs (to be fixed soon) and ufs. Changes since v1 [2]: - Add Acks I received - Rebase to v5.5-rc1, dropping patches that got merged already - Add NFS, XFS and the final three patches from another series - Rewrite etnaviv patches - Add one late revert to avoid an etnaviv regression [1] https://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground.git/log/?h=y2038-endgame [2] https://lore.kernel.org/lkml/20191108213257.3097633-1-arnd@arndb.de/ -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJeMYy3AAoJEGCrR//JCVInEGwP/0R+S+ok7vw9OdLVT0lFl07D IcVabgOWf24imN7m7L7Mlt3nDfxIT4tMpiAXq7eMO3spcyViG18O2LXdSQ4/7QBp +BlhoMjOP9w34Jyd7mnkFr4vqQALvfIqkS8rFObDtDub2Rfj9PC36MRMIu8BPXlv RK8bigwJeH/DV38yc5/JeUcD+WuewYLsK9XPWN+4yB4vgGsNU3ZQQ6nnzbR3hMsN DN8WZ68Y7IBs0Kyxkf+s2zmRXtCa2RiFg/2TUsk5olVAJVaenvte69hq5RSbg1vW vLi6K8cBoPWL59nqCzcNE+TUhSUg3LOj/a/KWyl76yovz7AlJaNjssOf8ZjHw6sL MhQqz3hXTxiJDS2Jvbf1yojiYGlzrq/gqcRFGe9jPcZdieMc4/yZCx60G/Exa5Pu YdMcqMyDWPFyUAFQNWEF59HPheOdj6tb1KpJ6bwgCo3P7QqhLrU4z9w3Py4/ZfBO 4sWcWteSsD6MN/ADJ2WQ56nNxzM2AvkeVJKcF6FCkdngXX9T0GExmZz7SqB5Du99 9lNjIiD5E+LBa/Swo/7n49aYa8x06V1pmHYTZVh9Wkl+CZiO21umezQFrWsfaMTp xt3c6pFdMG5xNMGpreTAXOmf2R+T6O8IO2qQq/TYjzqOLH7QC830P7avkmml+cK1 LjOBE2TfSeO8Ru1dXV4t =wx0A -----END PGP SIGNATURE----- Merge tag 'y2038-drivers-for-v5.6-signed' of git://git.kernel.org:/pub/scm/linux/kernel/git/arnd/playground Pull y2038 updates from Arnd Bergmann: "Core, driver and file system changes These are updates to device drivers and file systems that for some reason or another were not included in the kernel in the previous y2038 series.
