stat: fix inconsistency between struct stat and struct compat_stat
struct stat (defined in arch/x86/include/uapi/asm/stat.h) has 32-bit st_dev and st_rdev; struct compat_stat (defined in arch/x86/include/asm/compat.h) has 16-bit st_dev and st_rdev followed by a 16-bit padding. This patch fixes struct compat_stat to match struct stat. [ Historical note: the old x86 'struct stat' did have that 16-bit field that the compat layer had kept around, but it was changes back in 2003 by "struct stat - support larger dev_t": https://git.kernel.org/pub/scm/linux/kernel/git/tglx/history.git/commit/?id=e95b2065677fe32512a597a79db94b77b90c968d and back in those days, the x86_64 port was still new, and separate from the i386 code, and had already picked up the old version with a 16-bit st_dev field ] Note that we can't change compat_dev_t because it is used by compat_loop_info. Also, if the st_dev and st_rdev values are 32-bit, we don't have to use old_valid_dev to test if the value fits into them. This fixes -EOVERFLOW on filesystems that are on NVMe because NVMe uses the major number 259.

KVM: x86/mmu: Resolve nx_huge_pages when kvm.ko is loaded
Resolve nx_huge_pages to true/false when kvm.ko is loaded, leaving it as
-1 is technically undefined behavior when its value is read out by
param_get_bool(), as boolean values are supposed to be '0' or '1'.
Alternatively, KVM could define a custom getter for the param, but the
auto value doesn't depend on the vendor module in any way, and printing
"auto" would be unnecessarily unfriendly to the user.
In addition to fixing the undefined behavior, resolving the auto value
also fixes the scenario where the auto value resolves to N and no vendor
module is loaded. Previously, -1 would result in Y being printed even
though KVM would ultimately disable the mitigation.
Rename the existing MMU module init/exit helpers to clarify that they're
invoked with respect to the vendor module, and add comments to document
why KVM has two separate "module init" flows.

x86/bug: Prevent shadowing in __WARN_FLAGS
The macro __WARN_FLAGS() uses a local variable named "f". This being a
common name, there is a risk of shadowing other variables.
For example, GCC would yield:

perf/x86/intel: Don't extend the pseudo-encoding to GP counters
The INST_RETIRED.PREC_DIST event (0x0100) doesn't count on SPR.

The encoding for INST_RETIRED.PREC_DIST is pseudo-encoding, which
doesn't work on the generic counters. However, current perf extends its
mask to the generic counters.
The pseudo event-code for a fixed counter must be 0x00. Check and avoid
extending the mask for the fixed counter event which using the
pseudo-encoding, e.g., ref-cycles and PREC_DIST event.
With the patch,

x86/percpu: Remove volatile from arch_raw_cpu_ptr().
The volatile attribute in the inline assembly of arch_raw_cpu_ptr() forces the compiler to always generate the code, even if the compiler can decide upfront that its result is not needed. For instance invoking __intel_pmu_disable_all(false) (like intel_pmu_snapshot_arch_branch_stack() does) leads to loading the address of &cpu_hw_events into the register while compiler knows that it has no need for it. This ends up with code like: | movq $cpu_hw_events, %rax #, tcp_ptr__ | add %gs:this_cpu_off(%rip), %rax # this_cpu_off, tcp_ptr__ | xorl %eax, %eax # tmp93 It also creates additional code within local_lock() with !RT && !LOCKDEP which is not desired. By removing the volatile attribute the compiler can place the function freely and avoid it if it is not needed in the end. By using the function twice the compiler properly caches only the variable offset and always loads the CPU-offset. this_cpu_ptr() also remains properly placed within a preempt_disable() sections because - arch_raw_cpu_ptr() assembly has a memory input ("m" (this_cpu_off)) - prempt_{dis,en}able() fundamentally has a 'barrier()' in it Therefore this_cpu_ptr() is already properly serialized and does not rely on the 'volatile' attribute. Remove volatile from arch_raw_cpu_ptr(). [ bigeasy: Added Linus' explanation why this_cpu_ptr() is not moved out of a preempt_disable() section without the 'volatile' attribute. ] Suggested-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Link: https://lore.kernel.org/r/20220328145810.86783-2-bigeasy@linutronix.de |

KVM: x86: Add wrappers for setting/clearing APICv inhibits
Add set/clear wrappers for toggling APICv inhibits to make the call sites more readable, and opportunistically rename the inner helpers to align with the new wrappers and to make them more readable as well. Invert the flag from "activate" to "set"; activate is painfully ambiguous as it's not obvious if the inhibit is being activated, or if APICv is being activated, in which case the inhibit is being deactivated. For the functions that take @set, swap the order of the inhibit reason and @set so that the call sites are visually similar to those that bounce through the wrapper.

KVM: x86: Make APICv inhibit reasons an enum and cleanup naming
Use an enum for the APICv inhibit reasons, there is no meaning behind their values and they most definitely are not "unsigned longs". Rename the various params to "reason" for consistency and clarity (inhibit may be confused as a command, i.e. inhibit APICv, instead of the reason that is getting toggled/checked). No functional change intended. Signed-off-by: Sean Christopherson <seanjc@google.com> Message-Id: <20220311043517.17027-2-seanjc@google.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> |

KVM: X86: Handle implicit supervisor access with SMAP
There are two kinds of implicit supervisor access implicit supervisor access when CPL = 3 implicit supervisor access when CPL < 3 Current permission_fault() handles only the first kind for SMAP. But if the access is implicit when SMAP is on, data may not be read nor write from any user-mode address regardless the current CPL. So the second kind should be also supported. The first kind can be detect via CPL and access mode: if it is supervisor access and CPL = 3, it must be implicit supervisor access. But it is not possible to detect the second kind without extra information, so this patch adds an artificial PFERR_EXPLICIT_ACCESS into @access. This extra information also works for the first kind, so the logic is changed to use this information for both cases. The value of PFERR_EXPLICIT_ACCESS is deliberately chosen to be bit 48 which is in the most significant 16 bits of u64 and less likely to be forced to change due to future hardware uses it. This patch removes the call to ->get_cpl() for access mode is determined by @access. Not only does it reduce a function call, but also remove confusions when the permission is checked for nested TDP. The nested TDP shouldn't have SMAP checking nor even the L2's CPL have any bearing on it. The original code works just because it is always user walk for NPT and SMAP fault is not set for EPT in update_permission_bitmask.

KVM: X86: Change the type of access u32 to u64
Change the type of access u32 to u64 for FNAME(walk_addr) and ->gva_to_gpa(). The kinds of accesses are usually combinations of UWX, and VMX/SVM's nested paging adds a new factor of access: is it an access for a guest page table or for a final guest physical address. And SMAP relies a factor for supervisor access: explicit or implicit. So @access in FNAME(walk_addr) and ->gva_to_gpa() is better to include all these information to do the walk. Although @access(u32) has enough bits to encode all the kinds, this patch extends it to u64: o Extra bits will be in the higher 32 bits, so that we can easily obtain the traditional access mode (UWX) by converting it to u32. o Reuse the value for the access kind defined by SVM's nested paging (PFERR_GUEST_FINAL_MASK and PFERR_GUEST_PAGE_MASK) as @error_code in kvm_handle_page_fault().

KVM: x86/pmu: Use different raw event masks for AMD and Intel
The third nybble of AMD's event select overlaps with Intel's IN_TX and
IN_TXCP bits. Therefore, we can't use AMD64_RAW_EVENT_MASK on Intel
platforms that support TSX.
Declare a raw_event_mask in the kvm_pmu structure, initialize it in
the vendor-specific pmu_refresh() functions, and use that mask for
PERF_TYPE_RAW configurations in reprogram_gp_counter().

If kvm->arch.tdp_mmu_zap_wq cannot be created, the failure has to be propagated up to kvm_mmu_init_vm and kvm_arch_init_vm. kvm_arch_init_vm also has to undo all the initialization, so group all the MMU initialization code at the beginning and handle cleaning up of kvm_page_track_init.

Add support for Intel CET-IBT, available since Tigerlake (11th gen), which is a
coarse grained, hardware based, forward edge Control-Flow-Integrity mechanism where any indirect CALL/JMP must target an ENDBR instruction or suffer #CP. Additionally, since Alderlake (12th gen)/Sapphire-Rapids, speculation is limited to 2 instructions (and typically fewer) on branch targets not starting with ENDBR. CET-IBT also limits speculation of the next sequential instruction after the indirect CALL/JMP [1]. CET-IBT is fundamentally incompatible with retpolines, but provides, as described above, speculation limits itself.

Networking changes for 5.18.
Core ---- - Introduce XDP multi-buffer support, allowing the use of XDP with jumbo frame MTUs and combination with Rx coalescing offloads (LRO). - Speed up netns dismantling (5x) and lower the memory cost a little. Remove unnecessary per-netns sockets. Scope some lists to a netns. Cut down RCU syncing. Use batch methods. Allow netdev registration to complete out of order. - Support distinguishing timestamp types (ingress vs egress) and maintaining them across packet scrubbing points (e.g. redirect). - Continue the work of annotating packet drop reasons throughout the stack. - Switch netdev error counters from an atomic to dynamically allocated per-CPU counters. - Rework a few preempt_disable(), local_irq_save() and busy waiting sections problematic on PREEMPT_RT. - Extend the ref_tracker to allow catching use-after-free bugs. BPF --- - Introduce "packing allocator" for BPF JIT images. JITed code is marked read only, and used to be allocated at page granularity. Custom allocator allows for more efficient memory use, lower iTLB pressure and prevents identity mapping huge pages from getting split. - Make use of BTF type annotations (e.g. __user, __percpu) to enforce the correct probe read access method, add appropriate helpers. - Convert the BPF preload to use light skeleton and drop the user-mode-driver dependency. - Allow XDP BPF_PROG_RUN test infra to send real packets, enabling its use as a packet generator. - Allow local storage memory to be allocated with GFP_KERNEL if called from a hook allowed to sleep. - Introduce fprobe (multi kprobe) to speed up mass attachment (arch bits to come later). - Add unstable conntrack lookup helpers for BPF by using the BPF kfunc infra. - Allow cgroup BPF progs to return custom errors to user space. - Add support for AF_UNIX iterator batching. - Allow iterator programs to use sleepable helpers. - Support JIT of add, and, or, xor and xchg atomic ops on arm64. - Add BTFGen support to bpftool which allows to use CO-RE in kernels without BTF info. - Large number of libbpf API improvements, cleanups and deprecations. Protocols --------- - Micro-optimize UDPv6 Tx, gaining up to 5% in test on dummy netdev. - Adjust TSO packet sizes based on min_rtt, allowing very low latency links (data centers) to always send full-sized TSO super-frames. - Make IPv6 flow label changes (AKA hash rethink) more configurable, via sysctl and setsockopt. Distinguish between server and client behavior. - VxLAN support to "collect metadata" devices to terminate only configured VNIs. This is similar to VLAN filtering in the bridge. - Support inserting IPv6 IOAM information to a fraction of frames. - Add protocol attribute to IP addresses to allow identifying where given address comes from (kernel-generated, DHCP etc.) - Support setting socket and IPv6 options via cmsg on ping6 sockets. - Reject mis-use of ECN bits in IP headers as part of DSCP/TOS. Define dscp_t and stop taking ECN bits into account in fib-rules. - Add support for locked bridge ports (for 802.1X). - tun: support NAPI for packets received from batched XDP buffs, doubling the performance in some scenarios. - IPv6 extension header handling in Open vSwitch. - Support IPv6 control message load balancing in bonding, prevent neighbor solicitation and advertisement from using the wrong port. Support NS/NA monitor selection similar to existing ARP monitor. - SMC - improve performance with TCP_CORK and sendfile() - support auto-corking - support TCP_NODELAY - MCTP (Management Component Transport Protocol) - add user space tag control interface - I2C binding driver (as specified by DMTF DSP0237) - Multi-BSSID beacon handling in AP mode for WiFi. - Bluetooth: - handle MSFT Monitor Device Event - add MGMT Adv Monitor Device Found/Lost events - Multi-Path TCP: - add support for the SO_SNDTIMEO socket option - lots of selftest cleanups and improvements - Increase the max PDU size in CAN ISOTP to 64 kB. Driver API ---------- - Add HW counters for SW netdevs, a mechanism for devices which offload packet forwarding to report packet statistics back to software interfaces such as tunnels. - Select the default NIC queue count as a fraction of number of physical CPU cores, instead of hard-coding to 8. - Expose devlink instance locks to drivers. Allow device layer of drivers to use that lock directly instead of creating their own which always runs into ordering issues in devlink callbacks. - Add header/data split indication to guide user space enabling of TCP zero-copy Rx. - Allow configuring completion queue event size. - Refactor page_pool to enable fragmenting after allocation. - Add allocation and page reuse statistics to page_pool. - Improve Multiple Spanning Trees support in the bridge to allow reuse of topologies across VLANs, saving HW resources in switches. - DSA (Distributed Switch Architecture): - replay and offload of host VLAN entries - offload of static and local FDB entries on LAG interfaces - FDB isolation and unicast filtering New hardware / drivers ---------------------- - Ethernet: - LAN937x T1 PHYs - Davicom DM9051 SPI NIC driver - Realtek RTL8367S, RTL8367RB-VB switch and MDIO - Microchip ksz8563 switches - Netronome NFP3800 SmartNICs - Fungible SmartNICs - MediaTek MT8195 switches - WiFi: - mt76: MediaTek mt7916 - mt76: MediaTek mt7921u USB adapters - brcmfmac: Broadcom BCM43454/6 - Mobile: - iosm: Intel M.2 7360 WWAN card Drivers ------- - Convert many drivers to the new phylink API built for split PCS designs but also simplifying other cases. - Intel Ethernet NICs: - add TTY for GNSS module for E810T device - improve AF_XDP performance - GTP-C and GTP-U filter offload - QinQ VLAN support - Mellanox Ethernet NICs (mlx5): - support xdp->data_meta - multi-buffer XDP - offload tc push_eth and pop_eth actions - Netronome Ethernet NICs (nfp): - flow-independent tc action hardware offload (police / meter) - AF_XDP - Other Ethernet NICs: - at803x: fiber and SFP support - xgmac: mdio: preamble suppression and custom MDC frequencies - r8169: enable ASPM L1.2 if system vendor flags it as safe - macb/gem: ZynqMP SGMII - hns3: add TX push mode - dpaa2-eth: software TSO - lan743x: multi-queue, mdio, SGMII, PTP - axienet: NAPI and GRO support - Mellanox Ethernet switches (mlxsw): - source and dest IP address rewrites - RJ45 ports - Marvell Ethernet switches (prestera): - basic routing offload - multi-chain TC ACL offload - NXP embedded Ethernet switches (ocelot & felix): - PTP over UDP with the ocelot-8021q DSA tagging protocol - basic QoS classification on Felix DSA switch using dcbnl - port mirroring for ocelot switches - Microchip high-speed industrial Ethernet (sparx5): - offloading of bridge port flooding flags - PTP Hardware Clock - Other embedded switches: - lan966x: PTP Hardward Clock - qca8k: mdio read/write operations via crafted Ethernet packets - Qualcomm 802.11ax WiFi (ath11k): - add LDPC FEC type and 802.11ax High Efficiency data in radiotap - enable RX PPDU stats in monitor co-exist mode - Intel WiFi (iwlwifi): - UHB TAS enablement via BIOS - band disablement via BIOS - channel switch offload - 32 Rx AMPDU sessions in newer devices - MediaTek WiFi (mt76): - background radar detection - thermal management improvements on mt7915 - SAR support for more mt76 platforms - MBSSID and 6 GHz band on mt7915 - RealTek WiFi: - rtw89: AP mode - rtw89: 160 MHz channels and 6 GHz band - rtw89: hardware scan - Bluetooth: - mt7921s: wake on Bluetooth, SCO over I2S, wide-band-speed (WBS) - Microchip CAN (mcp251xfd): - multiple RX-FIFOs and runtime configurable RX/TX rings - internal PLL, runtime PM handling simplification - improve chip detection and error handling after wakeup Signed-off-by: Jakub Kicinski <kuba@kernel.org> -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE6jPA+I1ugmIBA4hXMUZtbf5SIrsFAmI7YBcACgkQMUZtbf5S IrveSBAAmSNJlUK6vPsnNzs7IhsZnfI/AUjm2TCLZnlhKttbpI4A/4Pohk33V7RS FGX7f8kjEfhUwrIiLDgeCnztNHRECrCmk6aZc/jLEvecmTauJ+f6kjShkDY/wix+ AkPHmrZnQeLPAEVuljDdV+sL6ik08+zQL7PazIYHsaSKKC0MGQptRwcri8PLRAKE KPBAhVhleq2rAZ/ntprSN52F4Af6rpFTrPIWuN8Bqdbc9dy5094LT0mpOOWYvgr3 /DLvvAPuLemwyIQkjWknVKBRUAQcmNPC+BY3J8K3LRaiNhekGqOFan46BfqP+k2J 6DWu0Qrp2yWt4BMOeEToZR5rA6v5suUAMIBu8PRZIDkINXQMlIxHfGjZyNm0rVfw 7edNri966yus9OdzwPa32MIG3oC6PnVAwYCJAjjBMNS8sSIkp7wgHLkgWN4UFe2H K/e6z8TLF4UQ+zFM0aGI5WZ+9QqWkTWEDF3R3OhdFpGrznna0gxmkOeV2YvtsgxY cbS0vV9Zj73o+bYzgBKJsw/dAjyLdXoHUGvus26VLQ78S/VGunVKtItwoxBAYmZo krW964qcC89YofzSi8RSKLHuEWtNWZbVm8YXr75u6jpr5GhMBu0CYefLs+BuZcxy dw8c69cGneVbGZmY2J3rBhDkchbuICl8vdUPatGrOJAoaFdYKuw= =ELpe -----END PGP SIGNATURE----- Merge tag 'net-next-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: "The sprinkling of SPI drivers is because we added a new one and Mark sent us a SPI driver interface conversion pull request.

asm-generic updates for 5.18
There are three sets of updates for 5.18 in the asm-generic tree: - The set_fs()/get_fs() infrastructure gets removed for good. This was already gone from all major architectures, but now we can finally remove it everywhere, which loses some particularly tricky and error-prone code. There is a small merge conflict against a parisc cleanup, the solution is to use their new version. - The nds32 architecture ends its tenure in the Linux kernel. The hardware is still used and the code is in reasonable shape, but the mainline port is not actively maintained any more, as all remaining users are thought to run vendor kernels that would never be updated to a future release. There are some obvious conflicts against changes to the removed files. - A series from Masahiro Yamada cleans up some of the uapi header files to pass the compile-time checks. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmI69BsACgkQmmx57+YA GNn/zA//f4d5VTT0ThhRxRWTu9BdThGHoB8TUcY7iOhbsWu0X/913NItRC3UeWNl IdmisaXgVtirg1dcC2pWUmrcHdoWOCEGfK4+Zr2NhSWfuZDWvODHK9pGWk4WLnhe cQgUNBvIuuAMryGtrOBwHPO4TpfCyy2ioeVP36ZfcsWXdDxTrqfaq/56mk3sxIP6 sUTk1UEjut9NG4C9xIIvcSU50R3l6LryQE/H9kyTLtaSvfvTOvprcVYCq0GPmSzo DtQ1Wwa9zbJ+4EqoMiP5RrgQwWvOTg2iRByLU8ytwlX3e/SEF0uihvMv1FQbL8zG G8RhGUOKQSEhaBfc3lIkm8GpOVPh0uHzB6zhn7daVmAWtazRD2Nu59BMjipa+ims a8Z58iHH7jRAnKeEkVZqXKb1CEiUxaQx/IeVPzN4QlwMhDtwrI76LY7ZJ1zCqTGY ENG0yRLav1XselYBslOYXGtOEWcY5EZPWqLyWbp4P9vz2g0Fe0gZxoIOvPmNQc89 QnfXpCt7vm/DGkyO255myu08GOLeMkisVqUIzLDB9avlym5mri7T7vk9abBa2YyO CRpTL5gl1/qKPWuH1UI5mvhT+sbbBE2SUHSuy84btns39ZKKKynwCtdu+hSQkKLE h9pV30Gf1cLTD4JAE0RWlUgOmbBLVp34loTOexQj4MrLM1noOnw= =vtCN -----END PGP SIGNATURE----- Merge tag 'asm-generic-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull asm-generic updates from Arnd Bergmann: "There are three sets of updates for 5.18 in the asm-generic tree: - The set_fs()/get_fs() infrastructure gets removed for good.

Reenable ENQCMD/PASID support:
- Simplify the PASID handling to allocate the PASID once, associate it to the mm of a process and free it on mm_exit(). The previous attempt of refcounted PASIDs and dynamic alloc()/free() turned out to be error prone and too complex. The PASID space is 20bits, so the case of resource exhaustion is a pure academic concern. - Populate the PASID MSR on demand via #GP to avoid racy updates via IPIs. - Reenable ENQCMD and let objtool check for the forbidden usage of ENQCMD in the kernel. - Update the documentation for Shared Virtual Addressing accordingly. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmI4WpETHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoUfnD/0bY94rgEX4Uuy/mFQ1W8X8XlcyKrha 0/cRATb+4QV/pwJgGr2nClKhGlFMYPdJLvKMC1TCUPCVrLD1RNmluIZoFzeqXwhm jDdCcFOuGZ2D4ujDPWwOOpKBT1ytovnQa7+lH6QJyKkEqdcC2ncOvGJQoiRxRQIG 8wTVs/OUvQJ5ZhSZQMKQN4uMWMyHEjhbroYS30/uNi/598jTPgzlEoa14XocQ9Os nS6ALvjuc9MsJ34F61etMaJU1ZMI3Wx75u9QjEvX6hmJs87YdvgwE7lzJUKFDEuh gewM0wp2fTa8/azzP0eMiHTin56PqFdmllzRqXmilbZMEPOeI29dZVArCdpKcAn0 r9p1kJUT3Xl2G3Oir/OdCaaQHcznD1Y5ZFOyh12wgEucZ/rdeSr7nq7n5HoOL5Bw Q2o6YvTkE9DOL0nTN1lSXGiPspou7fzX0uUcRBrbJUS3sBv4zGIlaJXUaTVnSdAt VZj4LeOK7v2BjyeiOY0iaaIQd3xjmLUF0UjozXS5M13SoVcToZRbyWqhDzPvNuKA imQb/dnFpXhABgmuqAiJLeqM0VtGMFNc780OURkcsBSPng+iSEdV4DzuhK0jpU8x Uk1RuGMd/vgmrlDFBrw+orQQiiKR1ixpI0LiHfcOBycfJhqTwcnrNZvAN5/do28Z E23+QzlUbZF0cw== =Dy8V -----END PGP SIGNATURE----- Merge tag 'x86-pasid-2022-03-21' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 PASID support from Thomas Gleixner: "Reenable ENQCMD/PASID support: - Simplify the PASID handling to allocate the PASID once, associate it to the mm of a process and free it on mm_exit().

KVM: x86: Introduce KVM_CAP_DISABLE_QUIRKS2
KVM_CAP_DISABLE_QUIRKS is irrevocably broken. The capability does not advertise the set of quirks which may be disabled to userspace, so it is impossible to predict the behavior of KVM. Worse yet, KVM_CAP_DISABLE_QUIRKS will tolerate any value for cap->args[0], meaning it fails to reject attempts to set invalid quirk bits. The only valid workaround for the quirky quirks API is to add a new CAP. Actually advertise the set of quirks that can be disabled to userspace so it can predict KVM's behavior. Reject values for cap->args[0] that contain invalid bits. Finally, add documentation for the new capability and describe the existing quirks.
