2022-01-28net: dsa: realtek: rename realtek_smi to realtek_privLuiz Angelo Daros de Luca
In preparation to adding other interfaces, the private data structure was renamed to priv. Also, realtek_smi_variant and realtek_smi_ops were renamed to realtek_variant and realtek_ops as those structs are not SMI specific.

2022-01-28ax25: add refcount in ax25_dev to avoid UAF bugsDuoming Zhou
If we dereference ax25_dev after we call kfree(ax25_dev) in ax25_dev_device_down(), it will lead to concurrency UAF bugs. There are eight syscall functions suffer from UAF bugs, include ax25_bind(), ax25_release(), ax25_connect(), ax25_ioctl(), ax25_getname(), ax25_sendmsg(), ax25_getsockopt() and ax25_info_show(). One of the concurrency UAF can be shown as below: (USE) | (FREE) | ax25_device_event | ax25_dev_device_down ax25_bind | ... ... | kfree(ax25_dev) ax25_fillin_cb() | ... ax25_fillin_cb_from_dev() | ... | The root cause of UAF bugs is that kfree(ax25_dev) in ax25_dev_device_down() is not protected by any locks. When ax25_dev, which there are still pointers point to, is released, the concurrency UAF bug will happen. This patch introduces refcount into ax25_dev in order to guarantee that there are no pointers point to it when ax25_dev is released.

2022-01-28ax25: improve the incomplete fix to avoid UAF and NPD bugsDuoming Zhou
The previous commit 1ade48d0c27d ("ax25: NPD bug when detaching AX25 device") introduce lock_sock() into ax25_kill_by_device to prevent NPD bug. But the concurrency NPD or UAF bug will occur, when lock_sock() or release_sock() dereferences the ax25_cb->sock. The NULL pointer dereference bug can be shown as below: ax25_kill_by_device() | ax25_release() | ax25_destroy_socket() | ax25_cb_del() ... | ... | ax25->sk=NULL; lock_sock(s->sk); //(1) | s->ax25_dev = NULL; | ... release_sock(s->sk); //(2) | ... | The root cause is that the sock is set to null before dereference site (1) or (2). Therefore, this patch extracts the ax25_cb->sock in advance, and uses ax25_list_lock to protect it, which can synchronize with ax25_cb_del() and ensure the value of sock is not null before dereference sites. The concurrency UAF bug can be shown as below: ax25_kill_by_device() | ax25_release() | ax25_destroy_socket() ... | ... | sock_put(sk); //FREE lock_sock(s->sk); //(1) | s->ax25_dev = NULL; | ... release_sock(s->sk); //(2) | ... | The root cause is that the sock is released before dereference site (1) or (2). Therefore, this patch uses sock_hold() to increase the refcount of sock and uses ax25_list_lock to protect it, which can synchronize with ax25_cb_del() in ax25_destroy_socket() and ensure the sock wil not be released before dereference sites.

Jakub Kicinski says: ==================== ethtool: add header/data split indication TCP ZC Rx requires data to be placed neatly into pages, separate from the networking headers. This is not supported by most devices so to make deployment easy this set adds a way for the driver to report support for this feature thru ethtool. The larger scope of configuring splitting headers and data, or DMA scatter seems dauntingly broad, so this set focuses specifically on the question "is this device usable with TCP ZC Rx?". The aim is to avoid a litany of conditions on HW platforms, features, and firmware versions in orchestration systems when the drivers can easily tell their SG config. ==================== Signed-off-by: David S.

2022-01-28ethtool: add header/data split indicationJakub Kicinski
For applications running on a mix of platforms it's useful to have a clear indication whether host's NIC supports the geometry requirements of TCP zero-copy. TCP zero-copy Rx requires data to be neatly placed into memory pages. Most NICs can't do that. This patch is adding GET support only, since the NICs I work with either always have the feature enabled or enable it whenever MTU is set to jumbo. In other words I don't need SET. But adding set should be trivial. (The only note on SET is that we will likely want the setting to be "sticky" and use 0 / `unknown` to reset it back to driver default.)

2022-01-28KVM: nVMX: Allow VMREAD when Enlightened VMCS is in useVitaly Kuznetsov
Hyper-V TLFS explicitly forbids VMREAD and VMWRITE instructions when Enlightened VMCS interface is in use: "Any VMREAD or VMWRITE instructions while an enlightened VMCS is active is unsupported and can result in unexpected behavior."" Windows 11 + WSL2 seems to ignore this, attempts to VMREAD VMCS field 0x4404 ("VM-exit interruption information") are observed. Failing these attempts with nested_vmx_failInvalid() makes such guests unbootable. Microsoft confirms this is a Hyper-V bug and claims that it'll get fixed eventually but for the time being we need a workaround. (Temporary) allow VMREAD to get data from the currently loaded Enlightened VMCS.

In preparation to allowing reads from Enlightened VMCS from handle_vmread(), implement evmcs_field_offset() to get the correct read offset. get_evmcs_offset(), which is being used by KVM-on-Hyper-V, is almost what's needed but a few things need to be adjusted. First, WARN_ON() is unacceptable for handle_vmread() as any field can (in theory) be supplied by the guest and not all fields are defined in eVMCS v1. Second, we need to handle 'holes' in eVMCS (missing fields). It also sounds like a good idea to WARN_ON() if such fields are ever accessed by KVM-on-Hyper-V.

2022-01-28ath11k: avoid firmware crash when reg set for QCA6390/WCN6855Wen Gong
For the NL80211_REGDOM_SET_BY_USER hint from cfg80211, it set the new alpha2 code to ath11k, then ath11k send WMI_SET_INIT_COUNTRY_CMDID to firmware for all chips currently. When test with WCN6855/QCA6390 chips, this WMI CMD leads firmware crash. For AP based chips(ipq8074/qcn9074), WMI_SET_INIT_COUNTRY_CMDID is used to send to firmware, for STATION based chips(WCN6855/QCA6390), it need to use another WMI CMD WMI_SET_CURRENT_COUNTRY_CMDID.

2022-01-28KVM: x86: add system attribute to retrieve full set of supported xsave statesPaolo Bonzini
Because KVM_GET_SUPPORTED_CPUID is meant to be passed (by simple-minded VMMs) to KVM_SET_CPUID2, it cannot include any dynamic xsave states that have not been enabled. Probing those, for example so that they can be passed to ARCH_REQ_XCOMP_GUEST_PERM, requires a new ioctl or arch_prctl. The latter is in fact worse, even though that is what the rest of the API uses, because it would require supported_xcr0 to be moved from the KVM module to the kernel just for this use. In addition, the value would be nonsensical (or an error would have to be returned) until the KVM module is loaded in. Therefore, to limit the growth of system ioctls, add a /dev/kvm variant of KVM_{GET,HAS}_DEVICE_ATTR, and implement it in x86 with just one group (0) and attribute (KVM_X86_XCOMP_GUEST_SUPP).

2022-01-28ath9k_htc: fix uninit value bugsPavel Skripkin
Syzbot reported 2 KMSAN bugs in ath9k. All of them are caused by missing field initialization. In htc_connect_service() svc_meta_len and pad are not initialized. Based on code it looks like in current skb there is no service data, so simply initialize svc_meta_len to 0. htc_issue_send() does not initialize htc_frame_hdr::control array. Based on firmware code, it will initialize it by itself, so simply zero whole array to make KMSAN happy Fail logs: BUG: KMSAN: kernel-usb-infoleak in usb_submit_urb+0x6c1/0x2aa0 drivers/usb/core/urb.c:430 usb_submit_urb+0x6c1/0x2aa0 drivers/usb/core/urb.c:430 hif_usb_send_regout drivers/net/wireless/ath/ath9k/hif_usb.c:127 [inline] hif_usb_send+0x5f0/0x16f0 drivers/net/wireless/ath/ath9k/hif_usb.c:479 htc_issue_send drivers/net/wireless/ath/ath9k/htc_hst.c:34 [inline] htc_connect_service+0x143e/0x1960 drivers/net/wireless/ath/ath9k/htc_hst.c:275 ...

2022-01-28KVM: x86: Add a helper to retrieve userspace address from kvm_device_attrSean Christopherson
Add a helper to handle converting the u64 userspace address embedded in struct kvm_device_attr into a userspace pointer, it's all too easy to forget the intermediate "unsigned long" cast as well as the truncation check.

2022-01-28xen/x2apic: enable x2apic mode when supported for HVMRoger Pau Monne
There's no point in disabling x2APIC mode when running as a Xen HVM guest, just enable it when available. Remove some unneeded wrapping around the detection functions, and simply provide a xen_x2apic_available helper that's a wrapper around x2apic_supported.

2022-01-28kselftest/arm64: Skip VL_INHERIT tests for unsupported vector typesMark Brown
Currently we unconditionally test the ability to set the vector length inheritance flag via ptrace meaning that we generate false failures on systems that don't support SVE when we attempt to set the vector length there. Check the hwcap and mark the tests as skipped when it's not present.
