2022-11-04tracing/fprobe: Fix to check whether fprobe is registered correctlyMasami Hiramatsu (Google)1-1/+2
Since commit ab51e15d535e ("fprobe: Introduce FPROBE_FL_KPROBE_SHARED flag for fprobe") introduced fprobe_kprobe_handler() for fprobe::ops::func, unregister_fprobe() fails to unregister the registered if user specifies FPROBE_FL_KPROBE_SHARED flag. Moreover, __register_ftrace_function() is possible to change the ftrace_ops::func, thus we have to check fprobe::ops::saved_func instead. To check it correctly, it should confirm the fprobe::ops::saved_func is either fprobe_handler() or fprobe_kprobe_handler().

2022-11-03arm64: cpufeature: Fix the visibility of compat hwcapsAmit Daniel Kachhap2-10/+70
Commit 237405ebef58 ("arm64: cpufeature: Force HWCAP to be based on the sysreg visible to user-space") forced the hwcaps to use sanitised user-space view of the id registers. However, the ID register structures used to select few compat cpufeatures (vfp, crc32, ...) are masked and hence such hwcaps do not appear in /proc/cpuinfo anymore for PER_LINUX32 personality. Add the ID register structures explicitly and set the relevant entry as visible. As these ID registers are now of type visible so make them available in 64-bit userspace by making necessary changes in register emulation logic and documentation. While at it, update the comment for structure ftr_generic_32bits[] which lists the ID register that use it.

2022-11-03arm64: efi: Recover from synchronous exceptions occurring in firmwareArd Biesheuvel4-2/+69
Unlike x86, which has machinery to deal with page faults that occur during the execution of EFI runtime services, arm64 has nothing like that, and a synchronous exception raised by firmware code brings down the whole system. With more EFI based systems appearing that were not built to run Linux (such as the Windows-on-ARM laptops based on Qualcomm SOCs), as well as the introduction of PRM (platform specific firmware routines that are callable just like EFI runtime services), we are more likely to run into issues of this sort, and it is much more likely that we can identify and work around such issues if they don't bring down the system entirely. Since we already use a EFI runtime services call wrapper in assembler, we can quite easily add some code that captures the execution state at the point where the call is made, allowing us to revert to this state and proceed execution if the call triggered a synchronous exception. Given that the kernel and the firmware don't share any data structures that could end up in an indeterminate state, we can happily continue running, as long as we mark the EFI runtime services as unavailable from that point on.

The SRCU read lock is not technically required when no Shadow MMUs are in use, since the TDP MMU walks the paging structures from the roots and does not need to look up GFN translations in the memslots, but make the SRCU locking unconditional for simplicty. In most cases, the SRCU locking is taken care of in the vCPU run loop, but when called through other ioctls (such as KVM_SET_GUEST_DEBUG) there is no srcu_read_lock. Tested: ran tools/testing/selftests/kvm/x86_64/debug_regs on a DBG build. This patch causes the suspicious RCU warning to disappear. Note that the warning is hit in __kvm_zap_rmaps(), so kvm_memslots_have_rmaps() must return true in order for this to repro (i.e. the TDP MMU must be off or nesting in use.)

2022-11-02ftrace: Fix use-after-free for dynamic ftrace_opsLi Huafei1-13/+3
KASAN reported a use-after-free with ftrace ops [1]. It was found from vmcore that perf had registered two ops with the same content successively, both dynamic. After unregistering the second ops, a use-after-free occurred. In ftrace_shutdown(), when the second ops is unregistered, the FTRACE_UPDATE_CALLS command is not set because there is another enabled ops with the same content. Also, both ops are dynamic and the ftrace callback function is ftrace_ops_list_func, so the FTRACE_UPDATE_TRACE_FUNC command will not be set. Eventually the value of 'command' will be 0 and ftrace_shutdown() will skip the rcu synchronization. However, ftrace may be activated. When the ops is released, another CPU may be accessing the ops. Add the missing synchronization to fix this problem.

2022-11-02ring-buffer: Check for NULL cpu_buffer in ring_buffer_wake_waiters()Steven Rostedt (Google)1-0/+11
On some machines the number of listed CPUs may be bigger than the actual CPUs that exist. The tracing subsystem allocates a per_cpu directory with access to the per CPU ring buffer via a cpuX file. But to save space, the ring buffer will only allocate buffers for online CPUs, even though the CPU array will be as big as the nr_cpu_ids. With the addition of waking waiters on the ring buffer when closing the file, the ring_buffer_wake_waiters() now needs to make sure that the buffer is allocated (with the irq_work allocated with it) before trying to wake waiters, as it will cause a NULL pointer dereference. While debugging this, I added a NULL check for the buffer itself (which is OK to do), and also NULL pointer checks against buffer->buffers (which is not fine, and will WARN) as well as making sure the CPU number passed in is within the nr_cpu_ids (which is also not fine if it isn't).

2022-11-02drm/amdgpu: Disable GPU reset on SRIOV before remove pci.Gavin Wan1-1/+2
The recent change brought a bug on SRIOV envrionment. It caused unloading amdgpu failed on Guest VM. The reason is that the VF FLR was requested while unloading amdgpu driver, but the VF FLR of SRIOV sequence is wrong while removing PCI device. For SRIOV, the guest driver should not trigger the whole XGMI hive to do the reset. Host driver control how the device been reset.

When disconnecting an ISO link the controller may not generate HCI_EV_NUM_COMP_PKTS for unacked packets which needs to be restored in hci_conn_del otherwise the host would assume they are still in use and would not be able to use all the buffers available.
