2022-12-13igb: Initialize mailbox message for VF resetTony Nguyen
When a MAC address is not assigned to the VF, that portion of the message sent to the VF is not set. The memory, however, is allocated from the stack meaning that information may be leaked to the VM. Initialize the message buffer to 0 so that no information is passed to the VM in this case.

2022-12-14LoongArch/ftrace: Add dynamic function tracer supportQing Zhang
The compiler has inserted 2 NOPs before the regular function prologue. T series registers are available and safe because of LoongArch's psABI. At runtime, we can replace nop with bl to enable ftrace call and replace bl with nop to disable ftrace call. The bl instruction requires us to save the original RA value, so it saves RA at t0 here. Details are: | Compiled | Disabled | Enabled | +------------+------------------------+------------------------+ | nop | move t0, ra | move t0, ra | | nop | nop | bl ftrace_caller | | func_body | func_body | func_body | The RA value will be recovered by ftrace_regs_entry, and restored into RA before returning to the regular function prologue. When a function is not being traced, the "move t0, ra" is not harmful. 1) ftrace_make_call, ftrace_make_nop (in kernel/ftrace.c) The two functions turn each recorded call site of filtered functions into a call to ftrace_caller or nops. 2) ftracce_update_ftrace_func (in kernel/ftrace.c) turns the nops at ftrace_call into a call to a generic entry for function tracers. 3) ftrace_caller (in kernel/mcount_dyn.S) The entry where each _mcount call sites calls to once they are filtered to be traced.

2022-12-14LoongArch/ftrace: Add recordmcount supportQing Zhang
Recordmcount utility under scripts is run, after compiling each object, to find out all the locations of calling _mcount() and put them into specific seciton named __mcount_loc. Then the linker collects all such information into a table in the kernel image (between __start_mcount_loc and __stop_mcount_loc) for later use by ftrace. This patch adds LoongArch specific definitions to identify such locations. And on LoongArch, only the C version is used to build the kernel now that CONFIG_HAVE_C_RECORDMCOUNT is on.

Use `-pg` makes stub like a child function `void _mcount(void *ra)`. Thus, it can be seen store RA and alloc stack before `call _mcount`. Find `alloc stack` at first, and then find `store RA`. Note that the functions in both inst.c and time.c should not be hooked with the compiler's -pg option: to prevent infinite self-referencing for the former, and to ignore early setup stuff for the latter.

2022-12-14LoongArch: module: Use got/plt section indices for relocationsHuacai Chen
Instead of saving a pointer to the .got, .plt and .plt_idx sections to apply {got,plt}-based relocations, save and use their section indices instead. The mod->arch.{core,init}.{got,plt} pointers were problematic for live- patch because they pointed within temporary section headers (provided by the module loader via info->sechdrs) that would be freed after module load. Since livepatch modules may need to apply relocations post-module- load (for example, to patch a module that is loaded later), using section indices to offset into the section headers (instead of accessing them through a saved pointer) allows livepatch modules on LoongArch to pass in their own copy of the section headers to apply_relocate_add() to apply delayed relocations. The method used is same as commit c8ebf64eab743 ("arm64/module: use plt section indices for relocations").

2022-12-14LoongArch: BPF: Add BPF exception tablesYouling Tang
Inspired by commit 800834285361("bpf, arm64: Add BPF exception tables"), do similar to LoongArch to add BPF exception tables. When a tracing BPF program attempts to read memory without using the bpf_probe_read() helper, the verifier marks the load instruction with the BPF_PROBE_MEM flag. Since the LoongArch JIT does not currently recognize this flag it falls back to the interpreter. Add support for BPF_PROBE_MEM, by appending an exception table to the BPF program. If the load instruction causes a data abort, the fixup infrastructure finds the exception table and fixes up the fault, by clearing the destination register and jumping over the faulting instruction. To keep the compact exception table entry format, inspect the pc in fixup_exception(). A more generic solution would add a "handler" field to the table entry, like on x86, s390 and arm64, etc. Signed-off-by: Youling Tang <tangyouling@loongson.cn> Signed-off-by: Huacai Chen <chenhuacai@loongson.cn>

2022-12-14LoongArch: extable: Add `type` and `data` fieldsYouling Tang
This is a LoongArch port of commit d6e2cc564775 ("arm64: extable: add `type` and `data` fields"). Subsequent patches will add specialized handlers for fixups, in addition to the simple PC fixup we have today. In preparation, this patch adds a new `type` field to struct exception_table_entry, and uses this to distinguish the fixup and other cases. A `data` field is also added so that subsequent patches can associate data specific to each exception site (e.g. register numbers). Handlers are named ex_handler_*() for consistency, following the example of x86. At the same time, get_ex_fixup() is split out into a helper so that it can be used by other ex_handler_*() functions in the subsequent patches.

2022-12-14LoongArch: Switch to relative exception tablesYouling Tang
Similar to other architectures such as arm64, x86, riscv and so on, use offsets relative to the exception table entry values rather than their absolute addresses for both the exception location and the fixup. However, LoongArch label difference because it will actually produce two relocations, a pair of R_LARCH_ADD32 and R_LARCH_SUB32. Take simple code below for example: $ cat test_ex_table.S .section .text 1: nop .section __ex_table,"a" .balign 4 .long (1b - .) .previous $ loongarch64-unknown-linux-gnu-gcc -c test_ex_table.S $ loongarch64-unknown-linux-gnu-readelf -Wr test_ex_table.o Relocation section '.rela__ex_table' at offset 0x100 contains 2 entries: Offset Info Type Symbol's Value Symbol's Name + Addend 0000000000000000 0000000600000032 R_LARCH_ADD32 0000000000000000 .L1^B1 + 0 0000000000000000 0000000500000037 R_LARCH_SUB32 0000000000000000 L0^A + 0 The modpost will complain the R_LARCH_SUB32 relocation, so we need to patch modpost.c to skip this relocation for .rela__ex_table section.

This should allow loaders such as GRUB or systemd-boot to reduce the amount of arch-specific handling substantially. - (arm64) Run EFI runtime services from a dedicated stack, and use it to recover from synchronous exceptions that might occur in the firmware code. - (arm64) Ensure that we don't allocate memory outside of the 48-bit addressable physical range. - Make EFI pstore record size configurable - Add support for decoding CXL specific CPER records" * tag 'efi-next-for-v6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi: (43 commits) arm64: efi: Recover from synchronous exceptions occurring in firmware arm64: efi: Execute runtime services from a dedicated stack arm64: efi: Limit allocations to 48-bit addressable physical region efi: Put Linux specific magic number in the DOS header efi: libstub: Always enable initrd command line loader and bump version efi: stub: use random seed from EFI variable efi: vars: prohibit reading random seed variables efi: random: combine bootloader provided RNG seed with RNG protocol output efi/cper, cxl: Decode CXL Error Log efi/cper, cxl: Decode CXL Protocol Error Section efi: libstub: fix efi_load_initrd_dev_path() kernel-doc comment efi: x86: Move EFI runtime map sysfs code to arch/x86 efi: runtime-maps: Clarify purpose and enable by default for kexec efi: pstore: Add module parameter for setting the record size efi: xen: Set EFI_PARAVIRT for Xen dom0 boot on all architectures efi: memmap: Move manipulation routines into x86 arch tree efi: memmap: Move EFI fake memmap support into x86 arch tree efi: libstub: Undeprecate the command line initrd loader efi: libstub: Add mixed mode support to command line initrd loader efi: libstub: Permit mixed mode return types other than efi_status_t ...
