--- Comment #3 from Mark Johnston <ma...@freebsd.org> --- I think this is a problem with truss rather than the kernel. Really there's two problems: 1. We don't define distinct syscall argument structures for Linux32 vs Linux64. That is, freebsd32_posix_fadvise_args splits the off_t arguments into two fields, but linux_fadvise64_args (used in the Linux32 sysent table) does not. So for a posix_fadvise() call in a 32-bit FreeBSD binary on amd64, truss prints: freebsd32_posix_fadvise(0x1,0x2,0x0,0x3,0x0,0x4) ERR#19 'Operation not supported by device' Obviously not perfect either, but at least you can see what's happening. 2. truss doesn't call quad_fixup() on 64-bit platforms even when the target ABI is freebsd32 or linux32. Otherwise it could fix the splitting that I described above and always print four arguments like one would expect. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-emulation@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-emulation To unsubscribe, send any mail to "freebsd-emulation-unsubscr...@freebsd.org"
