       - A fix for a 5.19 regression for a case in which early device tree
         initializes the RNG, which flips a static branch.
      
         On most plaforms, jump labels aren't initialized until much later, so
         this caused splats. On a few mailing list threads, we cooked up easy
         fixes for arm64, arm32, and risc-v. But then things looked slightly
         more involved for xtensa, powerpc, arc, and mips. And at that point,
         when we're patching 7 architectures in a place before the console is
         even available, it seems like the cost/risk just wasn't worth it.
      
         So random.c works around it now by checking the already exported
         `static_key_initialized` boolean, as though somebody already ran into
         this issue in the past. I'm not super jazzed about that; it'd be
         prettier to not have to complicate downstream code. But I suppose
         it's practical.
      
       - A few small code nits and adding a missing __init annotation.
      
       - A change to the default config values to use the cpu and bootloader's
         seeds for initializing the RNG earlier.
      
         This brings them into line with what all the distros do (Fedora/RHEL,
         Debian, Ubuntu, Gentoo, Arch, NixOS, Alpine, SUSE, and Void... at
         least), and moreover will now give us test coverage in various test
         beds that might have caught the above device tree bug earlier.
      
       - A change to WireGuard CI's configuration to increase test coverage
         around the RNG.
      
       - A documentation comment fix to unrelated maintainerless CRC code that
         I was asked to take, I guess because it has to do with polynomials
         (which the RNG thankfully no longer uses).

      iov_iter: fix build issue due to possible type mis-match · 1c27f1fc
      Linus Torvalds authored
      Commit 6c776766 ("iov_iter: Fix iter_xarray_get_pages{,_alloc}()")
      introduced a problem on some 32-bit architectures (at least arm, xtensa,
      csky,sparc and mips), that have a 'size_t' that is 'unsigned int'.
      
      The reason is that we now do
      
          min(nr * PAGE_SIZE - offset, maxsize);
      
      where 'nr' and 'offset' and both 'unsigned int', and PAGE_SIZE is
      'unsigned long'.  As a result, the normal C type rules means that the
      first argument to 'min()' ends up being 'unsigned long'.
      
      In contrast, 'maxsize' is of type 'size_t'.
      
      Now, 'size_t' and 'unsigned long' are always the same physical type in
      the kernel, so you'd think this doesn't matter, and from an actual
      arithmetic standpoint it doesn't.
      
      But on 32-bit architectures 'size_t' is commonly 'unsigned int', even if
      it could also be 'unsigned long'.  In that situation, both are unsigned
      32-bit types, but they are not the *same* type.
      
      And as a result 'min()' will complain about the distinct types (ignore
      the "pointer types" part of the error message: that's an artifact of the
      way we have made 'min()' check types for being the same):
      
        lib/iov_iter.c: In function 'iter_xarray_get_pages':
        include/linux/minmax.h:20:35: error: comparison of distinct pointer types lacks a cast [-Werror]
           20 |         (!!(sizeof((typeof(x) *)1 == (typeof(y) *)1)))
              |                                   ^~
        lib/iov_iter.c:1464:16: note: in expansion of macro 'min'
         1464 |         return min(nr * PAGE_SIZE - offset, maxsize);
              |                ^~~
      
      This was not visible on 64-bit architectures (where we always define
      'size_t' to be 'unsigned long').
      
      Force these cases to use 'min_t(size_t, x, y)' to make the type explicit
      and avoid the issue.
      
      [ Nit-picky note: technically 'size_t' doesn't have to match 'unsigned
        long' arithmetically. We've certainly historically seen environments
        with 16-bit address spaces and 32-bit 'unsigned long'.
      
        Similarly, even in 64-bit modern environments, 'size_t' could be its
        own type distinct from 'unsigned long', even if it were arithmetically
        identical.
      
        So the above type commentary is only really descriptive of the kernel
        environment, not some kind of universal truth for the kinds of wild
        and crazy situations that are allowed by the C standard ]

      wireguard: selftests: use maximum cpu features and allow rng seeding · 17b0128a
      Jason A. Donenfeld authored
      By forcing the maximum CPU that QEMU has available, we expose additional
      capabilities, such as the RNDR instruction, which increases test
      coverage. This then allows the CI to skip the fake seeding step in some
      cases. Also enable STRICT_KERNEL_RWX to catch issues related to early
      jump labels when the RNG is initialized at boot.
