fdopendir listed the directory from its first entry whatever position the
descriptor had, and left FD_CLOEXEC unchanged. FreeBSD 11.4 fdopendir sets
FD_CLOEXEC on the descriptor and preserves the initial seek position (lib/libc/gen/opendir.c).
The Windows directory handle now skips the entries the descriptor already
consumed, the Linux handle duplicates the descriptor, and the test requires both.

Measured from a payload process on a PS5 (firmware 12.70), where
__inet_ntop/__inet_pton and the plain inet_ntop/inet_pton exports
resolve to the same functions:
- inet_ntop follows an AF_INET6 result with zero bytes up to size (sizes
4 to 65536 sampled) and never writes past size; AF_INET writes only the
text and its NUL.
- An unsupported family returns EAFNOSUPPORT first, even with null
pointers.
- A null source or text raises SIGSEGV during the call, before the size
is checked; here it throws instead of returning EFAULT.
- A null destination is reached only after the size check and the text
parse: ENOSPC for a size that is too small, 0 for text that does not
parse, and SIGSEGV (a throw here) otherwise.
The test pins the measured inet_pton and inet_ntop rows, including all
inputs the existing assertions use. The text-form debt entry is replaced
by one that records what a payload process measured (the text forms, the
order of the checks and the padding) and what is still assumed: the
sizes that were not sampled, sizes above 65536, and a title process.
inet_ntoa_r calls __inet_ntop, so a null inet_ntoa_r buffer with room
for the text now throws, and a null buffer that is too small sets ENOSPC
instead of EFAULT; the libSceLibcInternal debt entry says so.
AI-assisted: yes

Dusklight (PPSA99305) aborts on main as soon as its Select disc image
item is chosen: SDL's file dialog probes "zenity --version" through
posix_spawnp, and posix_spawnp throws "process creation not implemented".
FreeBSD 11.4's posix_spawn returns the error of the child's exec, and
an exec of a program that is in no directory of PATH (_PATH_DEFPATH
when PATH is unset) fails with ENOENT. Both calls now return ENOENT
without writing the process ID when the program is not in the guest
file system, and keep throwing when it is. SDL then reports the file
dialog as unsupported and the title stays on its menu.

PS5CEMU-HAR (PPSA99360, ps5-payload-dev build, relinks with
--trap-sdk-syscall-stubs) imports the data objects sys_siglist
(yCdGspbNHZ8) and sys_nsig (ZD+Dp+-LsGg) from libSceLibcInternal.prx;
the import audit lists both as absent (registry entries 364 and 378,
after pthread_setaffinity_np at 276). No run has reached them yet; the
predicted stop line is
FAIL: unresolved ELF import ZD+Dp+-LsGg (sys_nsig) from libSceLibcInternal.prx
or yCdGspbNHZ8 (sys_siglist), whichever the loader resolves first.
The table and count are FreeBSD 11.4 lib/libc/gen/siglist.c (8c639945):
32 descriptions, signal 0 to SIGUSR2 (NSIG 32), and sys_nsig is their
number, 32. ps5-payload-dev declares both as objects exported by
libSceLibcInternal and its strsignal reads them.

XPSemu (PPSA97358) imports eleven posix_spawn calls from
libSceLibcInternal.prx, one reference each, and no call site is known.
Predicted stop (import order, not measured), behind isnanf (idx 296):
`FAIL: unresolved ELF import 44hlATrd47U from libSceLibcInternal.prx`
(posix_spawnattr_init, idx 347), followed by p--TkNVsXjA, LG6O0oW9bQU,
Sj7y+JO5PcM, Ud8CbISKRGM, Hq9-2AMG+ks, IUfBO5UIZNc, Heh4KJwyoX8 (348-355),
UV4m0bznVtU, Ani6e+T-y6Q and 3Nr9caNHhyg (379-381).
The nine object calls follow FreeBSD release/11.4.0 (8c639945a445)
lib/libc/gen/posix_spawn.c: posix_spawnattr_init allocates a zeroed
attribute object (ENOMEM on failure), _destroy frees it, _setflags and
_setsigdefault store the value; posix_spawn_file_actions_init allocates an
empty list (-1 on failure, as in 11.4), _destroy frees it with its
entries, and _addopen (path copied), _adddup2 and _addclose append in
order after returning EBADF for a negative descriptor. Null or
uninitialized objects, which FreeBSD dereferences, throw.
posix_spawn and posix_spawnp throw "process creation not implemented",
as execvp does: FreeBSD validates no argument before rfork/vfork, and no
child process can be created here. TechnicalDebt records them.
guest_posix_spawn covers the attribute round trips, the recorded action
sequence, the EBADF cases and the throws. NIDs computed with
tools/nid_names.py and present in aerolib.

Export getopt (VUtibKJCt1o) and getopt_long (8VVXJxB5nlk) from
libSceLibcInternal together with the guest variables optind
(zCnSJWp-Qj8), optarg (zG0BNJOZdm4), opterr (yaFXXViLWPw), optopt
(FwzVaZ8Vnus) and optreset (CZNm+oNmB-I). The NIDs were computed with
tools/nid_names.py and all seven are in aerolib; the PS5 payload SDK
f5d40f02 lists the functions and the five objects in
sce_stubs/libSceLibcInternal.c.
Titles (predicted stops from registry order, not observed runs):
- XPSemu PPSA97358, after execv/execve, the signal waits, the
credential setters, mlockall and tcsendbreak:
"FAIL: unresolved ELF import VUtibKJCt1o from libSceLibcInternal.prx"
(getopt idx 204, 10 call sites from 0xF6C23D), then optind (207),
optreset (208), optarg (209).
- RetroArch PPSA99169: getopt_long (idx 554, call sites 0xD2FC0C,
0xD3002A), optind (553), optarg (555).
Behaviour follows FreeBSD release/11.4.0 8c639945: getopt is
lib/libc/stdlib/getopt.c (no permutation, GNU "::" optional argument,
lone "-" as an option when listed), getopt_long is getopt_internal
from lib/libc/stdlib/getopt_long.c with GNU_COMPATIBLE (permutation,
POSIXLY_CORRECT read through the guest getenv on the first call and on
optreset, "+" and "-" prefixes, "W;", optind 0 as a reset, abbreviation
and ambiguity rules and the GNU warning texts). Warnings are written to
the guest stderr stream as "<__progname>: <message>", as warnx does.
The struct option layout and argument kinds are include/getopt.h.
The code lives in libSceLibcInternal because __progname is a libkernel
export that libc cannot link.
A null getopt option string, a null argument vector or argument, a
negative optind and an optind moved inside a pending permutation throw
where FreeBSD faults. getopt_long_only is not exported.
guest_getopt runs the FreeBSD getopt_test cases (contrib/netbsd-tests
t_getopt.sh with the h_getopt and h_getopt_long result format) plus
grouped and optional arguments, "--", permutation order, "+" and "-"
prefixes, optreset and optind 0 restarts, POSIXLY_CORRECT, all three
long argument kinds, abbreviations, ambiguity, flag pointers, "W;",
optopt with opterr 0 and the exact stderr text.
