      riscv: Allow device trees to be built into the kernel · 2d268251
      Palmer Dabbelt authored
      Some systems don't provide a useful device tree to the kernel on boot.
      Chasing around bootloaders for these systems is a headache, so instead
      le't's just keep a device tree table in the kernel, keyed by the SOC's
      unique identifier, that contains the relevant DTB.
      
      This is only implemented for M mode right now. While we could implement
      this via the SBI calls that allow access to these identifiers, we don't
      have any systems that need this right now.

       "Convert i2c_new_device() to i2c_new_client_device()
      
        Wolfram Sang has asked to have this included in 5.7 so the deprecated
        API can be removed next release. There should be no functional
        difference.
      
        I think that entire this section of code can be removed; it is
        leftover from other things that have since changed, but this is the
        safer thing to do for now. The full removal can happen next release"

      exec: Move would_dump into flush_old_exec · f87d1c95
      Eric W. Biederman authored
      I goofed when I added mm->user_ns support to would_dump.  I missed the
      fact that in the case of binfmt_loader, binfmt_em86, binfmt_misc, and
      binfmt_script bprm->file is reassigned.  Which made the move of
      would_dump from setup_new_exec to __do_execve_file before exec_binprm
      incorrect as it can result in would_dump running on the script instead
      of the interpreter of the script.
      
      The net result is that the code stopped making unreadable interpreters
      undumpable.  Which allows them to be ptraced and written to disk
      without special permissions.  Oops.
      
      The move was necessary because the call in set_new_exec was after
      bprm->mm was no longer valid.
      
      To correct this mistake move the misplaced would_dump from
      __do_execve_file into flos_old_exec, before exec_mmap is called.
      
      I tested and confirmed that without this fix I can attach with gdb to
      a script with an unreadable interpreter, and with this fix I can not.

       - A fix for unrecoverable SLB faults in the interrupt exit path,

         on 64-bit. These are all fairly minor with the exception of the
         change to evaluate the get/put_user() arguments before we enable user

         enabled.
      
       - A fix for our secure boot IMA rules, if enforcement of module
         signatures is enabled at runtime rather than build time.
      
       - A fix to our 32-bit VDSO clock_getres() which wasn't falling back to

        intermingling with !MMU.
      
        While some of these might be better hoisted to generic code, it seems
        better to have the simple fixes in the meanwhile.

      dpaa2-eth: properly handle buffer size restrictions · efa6a7d0
      Ioana Ciornei authored
      Depending on the WRIOP version, the buffer size on the RX path must by a
      multiple of 64 or 256. Handle this restriction properly by aligning down
      the buffer size to the necessary value. Also, use the new buffer size
      dynamically computed instead of the compile time one.

      ====================
      Small set of fixes in order to restrict BPF helpers for tracing which are
      broken on archs with overlapping address ranges as per discussion in [0].
      I've targetted this for -bpf tree so they can be routed as fixes. Thanks!
      
      v1 -> v2:
        - switch to reusable %pks, %pus format specifiers (Yonghong)
          - fixate %s on kernel_ds probing for archs with overlapping addr space

      bpf: Restrict bpf_trace_printk()'s %s usage and add %pks, %pus specifier · b2a5212f
      Daniel Borkmann authored
      Usage of plain %s conversion specifier in bpf_trace_printk() suffers from the
      very same issue as bpf_probe_read{,str}() helpers, that is, it is broken on
      archs with overlapping address ranges.
      
      While the helpers have been addressed through work in 6ae08ae3 ("bpf: Add
      probe_read_{user, kernel} and probe_read_{user, kernel}_str helpers"), we need
      an option for bpf_trace_printk() as well to fix it.
      
      Similarly as with the helpers, force users to make an explicit choice by adding
      %pks and %pus specifier to bpf_trace_printk() which will then pick the corresponding
      strncpy_from_unsafe*() variant to perform the access under KERNEL_DS or USER_DS.
      The %pk* (kernel specifier) and %pu* (user specifier) can later also be extended
      for other objects aside strings that are probed and printed under tracing, and
      reused out of other facilities like bpf_seq_printf() or BTF based type printing.
      
      Existing behavior of %s for current users is still kept working for archs where it
      is not broken and therefore gated through CONFIG_ARCH_HAS_NON_OVERLAPPING_ADDRESS_SPACE.
      For archs not having this property we fall-back to pick probing under KERNEL_DS as
      a sensible default.
      
      Fixes: 8d3b7dce ("bpf: add support for %s specifier to bpf_trace_printk()")

      bpf: Add bpf_probe_read_{user, kernel}_str() to do_refine_retval_range · 47cc0ed5
      Daniel Borkmann authored
      Given bpf_probe_read{,str}() BPF helpers are now only available under
      CONFIG_ARCH_HAS_NON_OVERLAPPING_ADDRESS_SPACE, we need to add the drop-in
      replacements of bpf_probe_read_{kernel,user}_str() to do_refine_retval_range()
      as well to avoid hitting the same issue as in 849fa506 ("bpf/verifier:

      bpf: Restrict bpf_probe_read{, str}() only to archs where they work · 0ebeea8c
      Daniel Borkmann authored
      Given the legacy bpf_probe_read{,str}() BPF helpers are broken on archs
      with overlapping address ranges, we should really take the next step to
      disable them from BPF use there.
      
      To generally fix the situation, we've recently added new helper variants
      bpf_probe_read_{user,kernel}() and bpf_probe_read_{user,kernel}_str().
      For details on them, see 6ae08ae3 ("bpf: Add probe_read_{user, kernel}
      and probe_read_{user,kernel}_str helpers").
      
      Given bpf_probe_read{,str}() have been around for ~5 years by now, there
      are plenty of users at least on x86 still relying on them today, so we
      cannot remove them entirely w/o breaking the BPF tracing ecosystem.
      
      However, their use should be restricted to archs with non-overlapping
      address ranges where they are working in their current form. Therefore,
      move this behind a CONFIG_ARCH_HAS_NON_OVERLAPPING_ADDRESS_SPACE and
      have x86, arm64, arm select it (other archs supporting it can follow-up
      on it as well).
      
      For the remaining archs, they can workaround easily by relying on the
      feature probe from bpftool which spills out defines that can be used out
      of BPF C code to implement the drop-in replacement for old/new kernels
      via: bpftool feature probe macro

      USB: gadget: fix illegal array access in binding with UDC · 15753588
      Kyungtae Kim authored
      FuzzUSB (a variant of syzkaller) found an illegal array access
      using an incorrect index while binding a gadget with UDC.
      
      Reference: https://www.spinics.net/lists/linux-usb/msg194331.html
      
      This bug occurs when a size variable used for a buffer
      is misused to access its strcpy-ed buffer.
      Given a buffer along with its size variable (taken from user input),
      from which, a new buffer is created using kstrdup().
      Due to the original buffer containing 0 value in the middle,
      the size of the kstrdup-ed buffer becomes smaller than that of the original.
      So accessing the kstrdup-ed buffer with the same size variable
      triggers memory access violation.
      
      The fix makes sure no zero value in the buffer,
      by comparing the strlen() of the orignal buffer with the size variable,
      so that the access to the kstrdup-ed buffer is safe.

      usb: core: hub: limit HUB_QUIRK_DISABLE_AUTOSUSPEND to USB5534B · 76e1ef1d

      The problem described in v5.6 commit 1208f9e1 ("USB: hub: Fix the
      broken detection of USB3 device in SMSC hub") applies solely to the
      USB5534B hub [2] present on the Kingfisher Infotainment Carrier Board,
      manufactured by Shimafuji Electric Inc [3].
      
      Despite that, the aforementioned commit applied the quirk to _all_ hubs
      carrying vendor ID 0x424 (i.e. SMSC), of which there are more [4] than
      initially expected. Consequently, the quirk is now enabled on platforms
      carrying SMSC/Microchip hub models which potentially don't exhibit the
      original issue.
      
      To avoid reports like [1], further limit the quirk's scope to
      USB5534B [2], by employing both Vendor and Product ID checks.
      
      Tested on H3ULCB + Kingfisher rev. M05.
