Mask off xfeatures that aren't exposed to the guest only when saving guest state via KVM_GET_XSAVE{2} instead of modifying user_xfeatures directly. Preserving the maximal set of xfeatures in user_xfeatures restores KVM's ABI for KVM_SET_XSAVE, which prior to commit ad856280 ("x86/kvm/fpu: Limit guest user_xfeatures to supported bits of XCR0") allowed userspace to load xfeatures that are supported by the host, irrespective of what xfeatures are exposed to the guest. There is no known use case where userspace *intentionally* loads xfeatures that aren't exposed to the guest, but the bug fixed by commit ad856280 was specifically that KVM_GET_SAVE{2} would save xfeatures that weren't exposed to the guest, e.g. would lead to userspace unintentionally loading guest-unsupported xfeatures when live migrating a VM. Restricting KVM_SET_XSAVE to guest-supported xfeatures is especially problematic for QEMU-based setups, as QEMU has a bug where instead of terminating the VM if KVM_SET_XSAVE fails, QEMU instead simply stops loading guest state, i.e. resumes the guest after live migration with incomplete guest state, and ultimately results in guest data corruption. Note, letting userspace restore all host-supported xfeatures does not fix setups where a VM is migrated from a host *without* commit ad856280, to a target with a subset of host-supported xfeatures. However there is no way to safely address that scenario, e.g. KVM could silently drop the unsupported features, but that would be a clear violation of KVM's ABI and so would require userspace to opt-in, at which point userspace could simply be updated to sanitize the to-be-loaded XSAVE state.

Plumb an xfeatures mask into __copy_xstate_to_uabi_buf() so that KVM can constrain which xfeatures are saved into the userspace buffer without having to modify the user_xfeatures field in KVM's guest_fpu state. KVM's ABI for KVM_GET_XSAVE{2} is that features that are not exposed to guest must not show up in the effective xstate_bv field of the buffer. Saving only the guest-supported xfeatures allows userspace to load the saved state on a different host with a fewer xfeatures, so long as the target host supports the xfeatures that are exposed to the guest. KVM currently sets user_xfeatures directly to restrict KVM_GET_XSAVE{2} to the set of guest-supported xfeatures, but doing so broke KVM's historical ABI for KVM_SET_XSAVE, which allows userspace to load any xfeatures that are supported by the *host*.

Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). While there, use struct_size() helper, instead of the open-coded version, to calculate the size for the allocation of the whole flexible structure, including of course, the flexible-array member.

Static calls invocations aren't well supported from module __init and __exit functions. Especially the static call from cleanup_trusted() led to a crash on x86 kernel with CONFIG_DEBUG_VIRTUAL=y. However, the usage of static call invocations for trusted_key_init() and trusted_key_exit() don't add any value from either a performance or security perspective. Hence switch to use indirect function calls instead. Note here that although it will fix the current crash report, ultimately the static call infrastructure should be fixed to either support its future usage from module __init and __exit functions or not.

This reverts commit 5f521494. The patch breaks mounts with security mount options like $ mount -o context=system_u:object_r:root_t:s0 /dev/sdX /mn mount: /mnt: wrong fs type, bad option, bad superblock on /dev/sdX, missing codepage or helper program, ... We cannot reject all unknown options in btrfs_parse_subvol_options() as intended, the security options can be present at this point and it's not possible to enumerate them in a future proof way. This means unknown mount options are silently accepted like before when the filesystem is mounted with either -o subvol=/path or as followup mounts of the same device.

Commit ff48b378 ("scsi: Do not attempt to rescan suspended devices") modified scsi_rescan_device() to avoid attempting rescanning a suspended device. However, the modification added a check to verify that a SCSI device is in the running state without checking if the device request queue (in the case of block device) is also running, thus allowing the exectuion of internal requests. Without checking the device request queue, commit ff48b378 fix is incomplete and deadlocks on resume can still happen. Use blk_queue_pm_only() to check if the device request queue allows executing commands in addition to checking the SCSI device state.

fit3 protocol driver does not support accessing IDE control registers (device control/altstatus). The DOS driver does not use these registers either (as observed from DOSEMU trace). But the HW seems to be capable of accessing these registers - I simply tried bit 3 and it works!

Some parallel adapters (e.g. EXP Computer MC-1285B EPP Cable) return bogus values when there's no master device present. This can cause reset to fail, preventing the lone slave device (such as EXP Computer CD-865) from working. Add custom version of wait_after_reset that ignores master failure when a slave device is present. The custom version is also needed because the generic ata_sff_wait_after_reset uses direct port I/O for slave device detection.

Ifcfg config file support in NetworkManger is deprecated. This patch provides support for the new keyfile config format for connection profiles in NetworkManager. The patch modifies the hv_kvp_daemon code to generate the new network configuration in keyfile format(.ini-style format) along with a ifcfg format configuration. The ifcfg format configuration is also retained to support easy backward compatibility for distro vendors. These configurations are stored in temp files which are further translated using the hv_set_ifconfig.sh script. This script is implemented by individual distros based on the network management commands supported. For example, RHEL's implementation could be found here: https://gitlab.com/redhat/centos-stream/src/hyperv-daemons/-/blob/c9s/hv_set_ifconfig.sh Debian's implementation could be found here: https://github.com/endlessm/linux/blob/master/debian/cloud-tools/hv_set_ifconfig The next part of this support is to let the Distro vendors consume these modified implementations to the new configuration format.

Commit 9e70a5e1 ("printk: Add per-console suspended state") removed console lock usage during resume and replaced it with the clearly defined console_list_lock and srcu mechanisms. However, the console lock usage had an important side-effect of flushing the consoles. After its removal, consoles were no longer flushed before checking their progress. Add the console_lock/console_unlock dance to the beginning of __pr_flush() to actually flush the consoles before checking their progress. Also add comments to clarify this additional usage of the console lock. Note that console_unlock() does not guarantee flushing all messages since the commit dbdda842 ("printk: Add console owner and waiter logic to load balance console writes").

In unprivileged Xen guests event handling can cause a deadlock with Xen console handling. The evtchn_rwlock and the hvc_lock are taken in opposite sequence in __hvc_poll() and in Xen console IRQ handling. Normally this is no problem, as the evtchn_rwlock is taken as a reader in both paths, but as soon as an event channel is being closed, the lock will be taken as a writer, which will cause read_lock() to block: CPU0 CPU1 CPU2 (IRQ handling) (__hvc_poll()) (closing event channel) read_lock(evtchn_rwlock) spin_lock(hvc_lock) write_lock(evtchn_rwlock) [blocks] spin_lock(hvc_lock) [blocks] read_lock(evtchn_rwlock) [blocks due to writer waiting, and not in_interrupt()] This issue can be avoided by replacing evtchn_rwlock with RCU in xen_free_irq(). Note that RCU is used only to delay freeing of the irq_info memory. There is no RCU based dereferencing or replacement of pointers involved. In order to avoid potential races between removing the irq_info reference and handling of interrupts, set the irq_info pointer to NULL only when freeing its memory. The IRQ itself must be freed at that time, too, as otherwise the same IRQ number could be allocated again before handling of the old instance would have been finished. This is XSA-441 / CVE-2023-34324.

Back in 2005, Kyle McMartin removed the 16-byte alignment for ldcw semaphores on PA 2.0 machines (CONFIG_PA20). This broke spinlocks on pre PA8800 processors. The main symptom was random faults in mmap'd memory (e.g., gcc compilations, etc). Unfortunately, the errata for this ldcw change is lost. The issue is the 16-byte alignment required for ldcw semaphore instructions can only be reduced to natural alignment when the ldcw operation can be handled coherently in cache. Only PA8800 and PA8900 processors actually support doing the operation in cache. Aligning the spinlock dynamically adds two integer instructions to each spinlock. Tested on rp3440, c8000 and a500.
