• 4b7775870   Introduce compat_u64 and compat_s64 types ... Browse Code »

  One common problem with 32 bit system call and ioctl emulation is the
  different alignment rules between i386 and 64 bit machines. A number of
  drivers work around this by marking the compat structures as
  'attribute((packed))', which is not the right solution because it breaks
  all the non-x86 architectures that want to use the same compat code.

  Hopefully, this patch improves the situation, it introduces two new types,
  compat_u64 and compat_s64. These are defined on all architectures to have
  the same size and alignment as the 32 bit version of u64 and s64.

• 202e5979a   [PATCH] compat: be more consistent about [ug]id_t ... Browse Code »

  When I first wrote the compat layer patches, I was somewhat cavalier about
  the definition of compat_uid_t and compat_gid_t (or maybe I just
  misunderstood :-)). This patch makes the compat types much more consistent
  with the types we are being compatible with and hopefully will fix a few
  bugs along the way.

  compat type type in compat arch
  __compat_[ug]id_t __kernel_[ug]id_t
  __compat_[ug]id32_t __kernel_[ug]id32_t
  compat_[ug]id_t [ug]id_t

  The difference is that compat_uid_t is always 32 bits (for the archs we
  care about) but __compat_uid_t may be 16 bits on some.

  Initial git repository build. I'm not bothering with the full history,
  even though we have it. We can create a separate "historical" git
  archive of that later if we want to, and in the meantime it's about
  3.2GB when imported into git - space that would just make the early
  git days unnecessarily complicated, when we don't have a lot of good
  infrastructure for it.

  Let it rip!
