I don't think this bug is valid; if it is, it's probably not fixable. The
uc_sigmask member is required to have type sigset_t, both by POSIX and in order
to be useful, (passing it to functions which take sigset_t pointers must work)
so there's no way to change it.

As in other bug using kernel headers in user program is invalid, report that to
kernel.

I don't see any use of kernel headers in the test case. But I also don't see
any evidence that there's a bug. uctxt->__fpregs_mem is not part of the public
API. For this bug to be valid, it would have to show observably wrong behavior
using the public API in a program not invoking undefined behavior.

The size of sigset_t in the ucontext_t structure as defined in the linux
kernel (I am using version 2.4.21-32.EL) does not match the size of the
sigset_t in the ucontext_t structure defined in the glibc header files. The
problem shows up in any user-level signal handler that cares to check. I've
attached a simple testcase that demonstrates an implication of the problem.
The kernel, by default, has the correct view. Thus, I am reporting the bug
here. Credit goes to Gregory Lueck for finding the bug.
Thanks,
Naveen Neelakantam
