      We've added 8 non-merge commits during the last 13 day(s) which contain
      a total of 21 files changed, 238 insertions(+), 161 deletions(-).
      
      The main changes are:
      
      1) Fix verification issues in some BPF programs due to their stack usage
         patterns, from Eduard Zingerman.
      
      2) Fix to add missing overflow checks in xdp_umem_reg and return an error
         in such case, from Kal Conley.
      
      3) Fix and undo poisoning of strlcpy in libbpf given it broke builds for
         libcs which provided the former like uClibc-ng, from Jesus Sanchez-Palencia.
      
      4) Fix insufficient bpf_jit_limit default to avoid users running into hard
         to debug seccomp BPF errors, from Daniel Borkmann.
      
      5) Fix driver return code when they don't support a bpf_xdp_metadata kfunc
         to make it unambiguous from other errors, from Jesper Dangaard Brouer.
      
      6) Two BPF selftest fixes to address compilation errors from recent changes
         in kernel structures, from Alexei Starovoitov.

      Bluetooth: HCI: Fix global-out-of-bounds · bce56405
      Sungwoo Kim authored
      To loop a variable-length array, hci_init_stage_sync(stage) considers
      that stage[i] is valid as long as stage[i-1].func is valid.
      Thus, the last element of stage[].func should be intentionally invalid
      as hci_init0[], le_init2[], and others did.
      However, amp_init1[] and amp_init2[] have no invalid element, letting
      hci_init_stage_sync() keep accessing amp_init1[] over its valid range.
      This patch fixes this by adding {} in the last of amp_init1[] and
      amp_init2[].

      Bluetooth: btqcomsmd: Fix command timeout after setting BD address · 5d44ab9e
      Stephan Gerhold authored
      On most devices using the btqcomsmd driver (e.g. the DragonBoard 410c
      and other devices based on the Qualcomm MSM8916/MSM8909/... SoCs)
      the Bluetooth firmware seems to become unresponsive for a while after
      setting the BD address. On recent kernel versions (at least 5.17+)
      this often causes timeouts for subsequent commands, e.g. the HCI reset
      sent by the Bluetooth core during initialization:
      
          Bluetooth: hci0: Opcode 0x c03 failed: -110
      
      Unfortunately this behavior does not seem to be documented anywhere.
      Experimentation suggests that the minimum necessary delay to avoid
      the problem is ~150us. However, to be sure add a sleep for > 1ms
      in case it is a bit longer on other firmware versions.
      
      Older kernel versions are likely also affected, although perhaps with
      slightly different errors or less probability. Side effects can easily
      hide the issue in most cases, e.g. unrelated incoming interrupts that
      cause the necessary delay.

      riscv: Handle zicsr/zifencei issues between clang and binutils · e89c2e81
      Nathan Chancellor authored
      There are two related issues that appear in certain combinations with
      clang and GNU binutils.
      
      The first occurs when a version of clang that supports zicsr or zifencei
      via '-march=' [1] (i.e, >= 17.x) is used in combination with a version
      of GNU binutils that do not recognize zicsr and zifencei in the
      '-march=' value (i.e., < 2.36):
      
        riscv64-linux-gnu-ld: -march=rv64i2p0_m2p0_a2p0_c2p0_zicsr2p0_zifencei2p0: Invalid or unknown z ISA extension: 'zifencei'
        riscv64-linux-gnu-ld: failed to merge target specific data of file fs/efivarfs/file.o
        riscv64-linux-gnu-ld: -march=rv64i2p0_m2p0_a2p0_c2p0_zicsr2p0_zifencei2p0: Invalid or unknown z ISA extension: 'zifencei'
        riscv64-linux-gnu-ld: failed to merge target specific data of file fs/efivarfs/super.o
      
      The second occurs when a version of clang that does not support zicsr or
      zifencei via '-march=' (i.e., <= 16.x) is used in combination with a
      version of GNU as that defaults to a newer ISA base spec, which requires
      specifying zicsr and zifencei in the '-march=' value explicitly (i.e, >=
      2.38):
      
        ../arch/riscv/kernel/kexec_relocate.S: Assembler messages:
        ../arch/riscv/kernel/kexec_relocate.S:147: Error: unrecognized opcode `fence.i', extension `zifencei' required
        clang-12: error: assembler command failed with exit code 1 (use -v to see invocation)
      
      This is the same issue addressed by commit 6df2a016 ("riscv: fix
      build with binutils 2.38") (see [2] for additional information) but
      older versions of clang miss out on it because the cc-option check
      fails:
      
        clang-12: error: invalid arch name 'rv64imac_zicsr_zifencei', unsupported standard user-level extension 'zicsr'
        clang-12: error: invalid arch name 'rv64imac_zicsr_zifencei', unsupported standard user-level extension 'zicsr'
      
      To resolve the first issue, only attempt to add zicsr and zifencei to
      the march string when using the GNU assembler 2.38 or newer, which is
      when the default ISA spec was updated, requiring these extensions to be
      specified explicitly. LLVM implements an older version of the base
      specification for all currently released versions, so these instructions
      are available as part of the 'i' extension. If LLVM's implementation is
      updated in the future, a CONFIG_AS_IS_LLVM condition can be added to
      CONFIG_TOOLCHAIN_NEEDS_EXPLICIT_ZICSR_ZIFENCEI.
      
      To resolve the second issue, use version 2.2 of the base ISA spec when
      using an older version of clang that does not support zicsr or zifencei
      via '-march=', as that is the spec version most compatible with the one
      clang/LLVM implements and avoids the need to specify zicsr and zifencei
      explicitly due to still being a part of 'i'.

      Reinstate "GFS2: free disk inode which is deleted by remote node -V2" · 260595b4
      Bob Peterson authored
      It turns out that reverting commit 970343cd ("GFS2: free disk inode
      which is deleted by remote node -V2") causes a regression related to
      evicting inodes that were unlinked on a different cluster node.
      
      We could also have simply added a call to d_mark_dontcache() to function
      gfs2_try_evict(), but the original pre-revert code is better tested and
      proven.

      efi/libstub: randomalloc: Return EFI_OUT_OF_RESOURCES on failure · 0b1d9deb
      Ard Biesheuvel authored
      The logic in efi_random_alloc() will iterate over the memory map twice,
      once to count the number of candidate slots, and another time to locate
      the chosen slot after randomization.
      
      If there is insufficient memory to do the allocation, the second loop
      will run to completion without actually having located a slot, but we
      currently return EFI_SUCCESS in this case, as we fail to initialize
      status to the appropriate error value of EFI_OUT_OF_RESOURCES.

      efi/libstub: Use relocated version of kernel's struct screen_info · fc3608aa
      Ard Biesheuvel authored
      In some cases, we expose the kernel's struct screen_info to the EFI stub
      directly, so it gets populated before even entering the kernel.  This
      means the early console is available as soon as the early param parsing
      happens, which is nice. It also means we need two different ways to pass
      this information, as this trick only works if the EFI stub is baked into
      the core kernel image, which is not always the case.
      
      Huacai reports that the preparatory refactoring that was needed to
      implement this alternative method for zboot resulted in a non-functional
      efifb earlycon for other cases as well, due to the reordering of the
      kernel image relocation with the population of the screen_info struct,
      and the latter now takes place after copying the image to its new
      location, which means we copy the old, uninitialized state.
      
      So let's ensure that the same-image version of alloc_screen_info()
      produces the correct screen_info pointer, by taking the displacement of
      the loaded image into account.
