+Regression tests for system calls ported from NetBSD.
+
+Reimplement ATF with many hacks to adjust the tests as little as possible.
+
+Tests passing without source file adjustments:
+t_access        t_getpid        t_kill          t_msgsnd        t_sigaction
+t_bind          t_link          t_msync         t_socketpair    t_getgroups
+t_getsid        t_listen        t_pipe          t_truncate      t_getitimer
+t_getsockname   t_mkdir         t_sendrecv      t_umask         t_getlogin
+t_gettimeofday  t_msgctl        t_setuid        t_write
+
+Tests passing after adjustments:
+t_chroot        - fchroot is not implemented
+t_clock_gettime - requires sysctlbyname
+t_dup           - OpenBSD dup3 is similar to Linux dup3
+t_fsync         - replace mkstemp
+t_getrusage     - no expected fail, PR kern/30115 is NetBSD, work more
+t_mknod         - remove tests for unsupported file types
+t_msgget        - remove msgget_limit test
+t_poll          - remove pollts_* tests
+t_revoke        - remove basic tests, revoke only on ttys supported
+t_select        - remove sigset_t struct as it is int on OpenBSD
+
+Failing tests:
+t_mkfifo        - every test case fails now
+t_mlock         - wrong errno, succeeds where not expected, POSIX imprecise
+t_mmap          - ENOTBLK on test NetBSD is skipping, remove mmap_va0 test
+t_msgrcv        - msgrcv(id, &r, 3 - 1, 0x41, 004000) != -1
+t_pipe2         - closefrom(4) == -1, remove F_GETNOSIGPIPE and nosigpipe test
+t_ptrace        - ptrace(0, 0, ((void *)0), 0) != -1
+t_stat          - invalid GID with doas
+t_syscall       - SIGSEGV
+t_unlink        - wrong errno according to POSIX
+

+t_clock_nanosleep       - not available
+t_clone                 - not available
