While it normally makes sense to require preemption to be off, so that the expected CPU's TLB is flushed and not another, in our case it really is best-effort (see comments in kfence_protect_page()). Avoid the warning by disabling preemption around flush_tlb_one_kernel().

ia64 has two stacks: - memory stack (or stack), pointed at by by r12 - register backing store (register stack), pointed at by ar.bsp/ar.bspstore with complications around dirty register frame on CPU. In [1] Dmitry noticed that PTRACE_GET_SYSCALL_INFO returns the register stack instead memory stack. The bug comes from the fact that user_stack_pointer() and current_user_stack_pointer() don't return the same register: ulong user_stack_pointer(struct pt_regs *regs) { return regs->ar_bspstore; } #define current_user_stack_pointer() (current_pt_regs()->r12) The change gets both back in sync. I think ptrace(PTRACE_GET_SYSCALL_INFO) is the only affected user by this bug on ia64. The change fixes 'rt_sigreturn.gen.test' strace test where it was observed initially.

The same deadlock was mentioned in upstream commit 28f5a8a7 ("ocfs2: should wait dio before inode lock in ocfs2_setattr()"). It seems that that commit only removed the cluster lock (the victim of above dead lock) from the ABBA deadlock party. End-user visible effects: Process hang in truncate -> ocfs2_setattr path and other processes hang at ocfs2_dio_end_io_write path. This is to fix the deadlock itself. It removes inode_lock() call from dio completion path to remove the deadlock and add ip_alloc_sem lock in setattr path to synchronize the inode modifications.

LLVM changed the expected function signature for llvm_gcda_emit_function() in the clang-11 release. Users of clang-11 or newer may have noticed their kernels producing invalid coverage information: $ llvm-cov gcov -a -c -u -f -b <input>.gcda -- gcno=<input>.gcno 1 <func>: checksum mismatch, \ (<lineno chksum A>, <cfg chksum B>) != (<lineno chksum A>, <cfg chksum C>) 2 Invalid .gcda File! ... Fix up the function signatures so calling this function interprets its parameters correctly and computes the correct cfg checksum. In particular, in clang-11, the additional checksum is no longer optional.

When we do coredump for user process signal, this may be an SIGBUS signal with BUS_MCEERR_AR or BUS_MCEERR_AO code, which means this signal is resulted from ECC memory fail like SRAR or SRAO, we expect the memory recovery work is finished correctly, then the get_dump_page() will not return the error page as its process pte is set invalid by memory_failure(). But memory_failure() may fail, and the process's related pte may not be correctly set invalid, for current code, we will return the poison page, get it dumped, and then lead to system panic as its in kernel code. So check the poison status in get_dump_page(), and if TRUE, return NULL. There maybe other scenario that is also better to check the posion status and not to panic, so make a wrapper for this check, Thanks to David's suggestion(<david@redhat.com>).

napi_disable() is subject to an hangup, when the threaded mode is enabled and the napi is under heavy traffic. If the relevant napi has been scheduled and the napi_disable() kicks in before the next napi_threaded_wait() completes - so that the latter quits due to the napi_disable_pending() condition, the existing code leaves the NAPI_STATE_SCHED bit set and the napi_disable() loop waiting for such bit will hang. This patch addresses the issue by dropping the NAPI_STATE_DISABLE bit test in napi_thread_wait(). The later napi_threaded_poll() iteration will take care of clearing the NAPI_STATE_SCHED. This also addresses a related problem reported by Jakub: before this patch a napi_disable()/napi_enable() pair killed the napi thread, effectively disabling the threaded mode. On the patched kernel napi_disable() simply stops scheduling the relevant thread. v1 -> v2: - let the main napi_thread_poll() loop clear the SCHED bit Reported-by:

The ethernet frame length is calculated incorrectly. Depending on the value of RX_HEAD_PADDING, this may result in ethernet frames that are too short (cut off at the end), or too long (garbage added to the end). Fix by calculating the ethernet frame length correctly. For added clarity, use the ETH_FCS_LEN constant in the calculation. Many thanks to Heiner Kallweit for suggesting this solution. Suggested-by:

When we suspend the VM, the VDPA interface will be reset. When the VM is resumed again, clear_virtqueues() will clear the available and used indices resulting in hardware virqtqueue objects becoming out of sync. We can avoid this function alltogether since qemu will clear them if required, e.g. when the VM went through a reboot. Moreover, since the hw available and used indices should always be identical on query and should be restored to the same value same value for virtqueues that complete in order, we set the single value provided by set_vq_state(). In get_vq_state() we return the value of hardware used index.
