    1.78 -It was reported to me that ucontext is utterly broken, even in o32
    1.79 -with a stable 32-bit mips kernel.  Indeed, it doesn't match the
    1.80 -ucontext structure defined by the kernel at all.  This means that
    1.81 -programs taking real-time signals in o32 won't be able to extract
    1.82 -correct information from the mcontext_t, since the kernel puts data in
    1.83 -there that's in an entirely different format.
    1.84 -
    1.85 -I've looked for any ways in which the current data structures could
    1.86 -possibly be useful, and didn't find any.  gdb and rda thought they
    1.87 -were using the register arrays, but it turned out they were using the
    1.88 -arrays in procps instead.  makecontext(), [sg]etcontext() et al aren't
    1.89 -implemented on mips, so any uses thereof will just return ENOSYS,
    1.90 -without messing with the given data structure.  So, I believe it is
    1.91 -not too late for us to fix it such that it matches the kernel data
    1.92 -structures.
    1.93 -
    1.94 -While at that, I fixed a number of incompatibilities introduced by
    1.95 -either differences between kernel headers that we used to include,
    1.96 -whose contents are different depending on whether asm points to
    1.97 -asm-mips or asm-mips64.
    1.98 -
    1.99 -With this patch, after some pending kernel patches are checked in, one
   1.100 -will be able to obtain the correct information from signal handlers in
   1.101 -all mips ABIs.  With n64, this is already true.  With o32, it works
   1.102 -with the 32-bit mips kernel, but the mips64 kernel needs a patch to
   1.103 -implement the proper sigcontext ABI.  n32 still a patch to be
   1.104 -developed for it to be possible for ucontext to be POSIX-compliant.
   1.105 -Currently, the kernel uses the same ucontext for n32 and n64, but this
   1.106 -doesn't work in n32 because uc_link must be a pointer and stack_t must
   1.107 -contain a pointer and a size_t, whose sizes differ between n32 and
   1.108 -n64.  I believe Ralf is working on a patch for the kernel to generate
   1.109 -n32-compliant ucontext when invoking signal handlers in n32 processes.
   1.110 -The only uncertainty is whether uc_flags will be a 32- or 64-bit value
   1.111 -in n32; I left it as the latter, just because I already had that in
   1.112 -place; if it changes, a (simplifying) follow-up patch will be posted.
   1.113 -However, I wanted to circulate the idea of fixing ucontext_t for o32
   1.114 -as soon as possible, so I didn't wait for a decision on the exact n32
   1.115 -ABI.
   1.116 -
   1.117 -Ok to install?
