To avoid an xtensa special-case, refactor all arch register macros to
take the register variable instead of depending on the macro expanding
as a struct member name.

In order to avoid "#ifdef"s in the main function bodies, create a new
macro, SYSCALL_NUM_SET(), where arch-specific logic can live.

SYSCALL_SWITCH(_regs, nr)?

I think that
# define SYSCALL_NUM_SET(_regs, _nr) \
do { \
if (SYSCALL_NUM(_regs) == __NR_O32_Linux) \
(_regs).regs[4] = _nr; \
else \
(_regs).regs[2] = _nr; \
} while (0)
would read better but that's just a matter of taste. :)

That's how I started originally, but when I realized that I'd have to
reorganize SYSCALL_NUM() too, it seem best to have minimal churn, so I
left it open coded here, since that's how it needs to be in the end.

Instead of having the mips O32 macro special-cased, pull the logic into
the SYSCALL_NUM() macro. Additionally include the ABI headers, since
these appear to have been missing, leaving __NR_O32_Linux undefined.

With all architectures now using the common SYSCALL_NUM_SET() macro, the
arch-specific #ifdef can be removed from change_syscall() itself.

When none of the registers have changed, don't flush them back. This can
happen if the architecture uses a non-register way to change the syscall
(e.g. arm64) , and a return value hasn't been written.

Instead of special-casing the specific case of shared registers, create
a default SYSCALL_RET_SET() macro (mirroring SYSCALL_NUM_SET()), that
writes to the SYSCALL_RET register. For architectures that can't set the
return value (for whatever reason), they can define SYSCALL_RET_SET()
without an associated SYSCALL_RET() macro. This also paves the way for
architectures that need to do special things to set the return value
(e.g. powerpc).

On powerpc, the errno is not inverted, and depends on ccr.so being
set. Add this to a powerpc definition of SYSCALL_RET_SET().

Some archs (like ppc) only support changing the return code during
syscall exit when ptrace is used. As the syscall number might not
be available anymore during syscall exit, it needs to be saved
during syscall enter. Adjust the ptrace tests to do this.

I'm not that across all the fixture stuff, but if I'm reading it right
you're now calling change_syscall() on both entry and exit for all
arches.
That should work, but it no longer tests changing the return code on
entry on the arches that support it, which seems like a backward step?

Correct.

That's a good point. I wouldn't be in a position to notice a regression
for the other architectures. I will refactor this one...

As the UAPI headers start to appear in distros, we need to avoid
outdated versions of struct clone_args to be able to test modern
features. Additionally pull in the syscall numbers correctly.

I needed to fix this to get MIPS to build the seccomp selftests.

The __NR_mknod syscall doesn't exist on arm64 (only __NR_mknodat).
Switch to the modern syscall.

The series builds fine for me, and all the tests pass (see below).
Thanks for picking up those changes to deal with powerpc being oddball.

Was this a mis-paste, or has something very very bad happened here in

I observe similar output corruption on xtensa when I redirect test output
into a file or pipe it to 'cat'. When it goes to the terminal it looks normal.

Haha, I thought that was normal :)
It's because of redirection, I run the tests with:
find . -executable -type f -print -execdir '{}' ';' | tee test.log
If I just run it directly on the terminal everything is normal.
It'll be fork() vs libc buffering.
I can fix it with:
$ stdbuf -oL ./seccomp_bpf | tee test.log
Or the patch below.
I can send a proper patch for that tomorrow, I don't know that harness
code, but I think that's the right fix.
cheers

I've built and tested this series on xtensa. I had to disable two tests:
user_notification_addfd and user_notification_addfd_rlimit because
they use memfd_create and prlimit which are not available in uClibc.
With this change I've got all 86 tests passing with the following log:
