Looking through the various asm-*/siginfo.h files in Linux 2.3.41pre2,
I've encountered only two platforms with problems: Alpha and Sparc.
Could the maintainers of these platforms please check the following
and take appropriate action?
Alpha defines:
#define SI_PAD_SIZE ((SI_MAX_SIZE/sizeof(int)) - 4)
#define SIGEV_PAD_SIZE ((SIGEV_MAX_SIZE/sizeof(int)) - 4)
but all other platforms have a 3 instead of a 4 for these two defines:
#define SI_PAD_SIZE ((SI_MAX_SIZE/sizeof(int)) - 3)
#define SIGEV_PAD_SIZE ((SIGEV_MAX_SIZE/sizeof(int)) - 3)
Sparc and Sparc64 additionally define the member _trapno for _sigfault
- and SIGEMT is also only used by Sparc*:
/* SIGILL, SIGFPE, SIGSEGV, SIGBUS, SIGEMT */
struct {
void *_addr; /* faulting insn/memory ref. */
int _trapno; /* TRAP # which caused the signal */
} _sigfault;
Do we need Linux/alpha and Linux/sparc versions of <bits/siginfo.h>?

(Again, something which I had scheduled for today anyway).
IMHO, we need only separate version of sparc siginfo, plus use __WORDSIZE
in the generic linux version (I think ia64, ppc64, mips64 etc. could use it
as well):
2000-01-24 Jakub Jelinek <jakub@redhat.com>
* sysdeps/unix/sysv/linux/bits/siginfo.h (__SI_PAD_SIZE,
__SIGEV_PAD_SIZE): Define differently on __WORDSIZE == 64 platforms.
* sysdeps/unix/sysv/linux/sparc/bits/siginfo.h: New file.
* sysdeps/unix/sysv/linux/sigqueue.c (__sigqueue): Make sure we don't
send random data from our stack.
* sysdeps/unix/sysv/linux/aio_sigqueue.c (__aio_sigqueue): Likewise.

Good that I didn't investigate more work into it;-).
Jakub, what do you think? Are now (with your patch and Linux
2.3.41pre2) all siginfo problems fixed? Is 32bit uid support complete
(apart from some cleaning up)?

The rest looks fine.

If Linus eats my siginfo kernel patch (it clashes with your NSIGCHLD,
hopefully Linus will want to resolve that failed hunk), then hopefully
all should be ready, apart from a few missing kernel siginfo generation points.
Now the whole thing has to be heavily tested with 2.3 and 2.2 kernels.

Oopsie, you're right, should be there as well.
On the other side, the comments are pretty misleading in SIGCHLD and SIGPOLL
cases. Those structure layouts are for child deatch signal (which can be any
signal) and you can pass si_band/si_fd with signals other than SIGPOLL as
well.
Cheers,
Jakub
