That one also exists on alpha and sparc. The other two are indeed

There must have been other cases of novel syscalls added to libseccomp
before?
Neither alpha nor sparc are supported by libseccomp, so I think that's
not an argument.
Explains why getpagesize still is not handled by libseccomp, then.
Now do any of the other architectures recently added to libseccomp
have non-standard
syscalls? (Trying to work out what commits might hold the secret to
adding support for
new syscalls...)
This interactive arch-wide chart table should be helpful for finding
this out:
https://marcin.juszkiewicz.com.pl/download/tables/syscalls.html
Look at include/seccomp-syscalls.h - I'd add the missing syscalls after
this one:
#define __PNR_memfd_secret -10244
(pseudo syscall numbers for the other architectures)
plus appropriate boilerplate such as this:
#ifdef __NR_memfd_secret
#define __SNR_memfd_secret __NR_memfd_secret
#else
#define __SNR_memfd_secret __PNR_memfd_secret
#endif
(actual syscall numbers from our arch/m68k/include/uapi/asm/unistd-32.h
used).
Just looked at the source, didn't try to build anything so I may be
missing something crucial here...
Cheers,
