2023-12-09LoongArch: Preserve syscall nr across execve()Hengqi Chen
Currently, we store syscall nr in pt_regs::regs[11] and syscall execve() accidentally overrides it during its execution: sys_execve() -> do_execve() -> do_execveat_common() -> bprm_execve() -> exec_binprm() -> search_binary_handler() -> load_elf_binary() -> ELF_PLAT_INIT() ELF_PLAT_INIT() reset regs[11] to 0, so in syscall_exit_to_user_mode() we later get a wrong syscall nr. This breaks tools like execsnoop since it relies on execve() tracepoints. Skip pt_regs::regs[11] reset in ELF_PLAT_INIT() to fix the issue.

2023-12-09LoongArch: Set unwind stack type to unknown rather than set error flagJinyang He
During unwinding, unwind_done() is used as an end condition. Normally it unwind to the user stack and then set the stack type to unknown, which is a normal exit. When something unexpected happens in unwind process and we cannot unwind anymore, we should set the error flag, and also set the stack type to unknown to indicate that the unwind process can not continue. The error flag emphasizes that the unwind process produce an unexpected error. There is no unexpected things when we unwind the PT_REGS in the top of IRQ stack and find out that is an user mode PT_REGS. Thus, we should not set error flag and just set stack type to unknown.

2023-12-09LoongArch: Apply dynamic relocations for LLDWANG Rui
For the following assembly code: .text .global func func: nop .data var: .dword func When linked with `-pie`, GNU LD populates the `var` variable with the pre-relocated value of `func`. However, LLVM LLD does not exhibit the same behavior. This issue also arises with the `kernel_entry` in arch/ loongarch/kernel/head.S: _head: .word MZ_MAGIC /* "MZ", MS-DOS header */ .org 0x8 .dword kernel_entry /* Kernel entry point */ The correct kernel entry from the MS-DOS header is crucial for jumping to vmlinux from zboot. This necessity is why the compressed relocatable kernel compiled by Clang encounters difficulties in booting. To address this problem, it is proposed to apply dynamic relocations to place with `--apply-dynamic-relocs`.

The dtbs_check really doesn't like having memory without reg set. The base address depends on the amount of RAM you have: <= 2.00 GiB RAM: 0x80000000 = 3.00 GiB RAM: 0x40000000 = 3.75 GiB RAM: 0x10000000 (more does not fit into the 32-bit physical address space) So, let's pick one of the values, 0x10000000 which is used on devices with 3.75 GiB RAM. Since the bootloader will update it to what's present on the device it doesn't matter too much.

2023-12-08KVM: SVM: Update EFER software model on CR0 trap for SEV-ESSean Christopherson
In general, activating long mode involves setting the EFER_LME bit in the EFER register and then enabling the X86_CR0_PG bit in the CR0 register. At this point, the EFER_LMA bit will be set automatically by hardware. In the case of SVM/SEV guests where writes to CR0 are intercepted, it's necessary for the host to set EFER_LMA on behalf of the guest since hardware does not see the actual CR0 write. In the case of SEV-ES guests where writes to CR0 are trapped instead of intercepted, the hardware *does* see/record the write to CR0 before exiting and passing the value on to the host, so as part of enabling SEV-ES support commit f1c6366e3043 ("KVM: SVM: Add required changes to support intercepts under SEV-ES") dropped special handling of the EFER_LMA bit with the understanding that it would be set automatically. However, since the guest never explicitly sets the EFER_LMA bit, the host never becomes aware that it has been set. This becomes problematic when userspace tries to get/set the EFER values via KVM_GET_SREGS/KVM_SET_SREGS, since the EFER contents tracked by the host will be missing the EFER_LMA bit, and when userspace attempts to pass the EFER value back via KVM_SET_SREGS it will fail a sanity check that asserts that EFER_LMA should always be set when X86_CR0_PG and EFER_LME are set. Fix this by always inferring the value of EFER_LMA based on X86_CR0_PG and EFER_LME, regardless of whether or not SEV-ES is enabled.

kvm-master KVM fixes for 6.7-rcN: - When checking if a _running_ vCPU is "in-kernel", i.e. running at CPL0, get the CPL directly instead of relying on preempted_in_kernel, which is valid if and only if the vCPU was preempted, i.e. NOT running. - Set .owner for various KVM file_operations so that files refcount the KVM module until KVM is done executing _all_ code, including the last few instructions of kvm_put_kvm(). And then revert the misguided attempt to rely on "struct kvm" refcounts to pin KVM-the-module. - Fix a benign "return void" that was recently introduced.
