ftruncate, truncate and sceKernelFtruncate extended a file through _chsize_s,
which writes the whole new length as zero bytes. FreeBSD extends the file
without writing data (kern_ftruncate -> ffs_truncate) and fails a length the
file system cannot hold with EFBIG. NativeFtruncate now sets the end of file
with SetFileInformationByHandle and maps ERROR_DISK_FULL to ENOSPC and
ERROR_FILE_TOO_LARGE/ERROR_INVALID_PARAMETER to EFBIG.

The debt entries only had the four index sections before; use Unknown
function info for the imports that fail a title to load and for the
signatures Orbital or the aerolib NID list do not give. Note that
sceSystemServiceShowDisplaySafeAreaSettings takes its (void) signature
from the sibling sceSystemServiceShowControllerSettings, not a reference.
AI-assisted: yes
SceCamera, SceDepth2, SceSulpha and SceAudiodecCpuHevag were declared
without parameters because no reference gives their signatures, and the
HEVAG stub exported an invented sceAudiodecCpuHevagUnimplemented symbol
that matches no real export. SceAudiodecCpu overlaps #6847. Only the
libraries whose real exports and signatures are known stay.
AI-assisted: yes
Add boilerplate stubs for libSceAt9Enc, libSceAudiodecCpu, libSceAudiodecCpuHevag,
libSceM4aacEnc, libSceSulpha, libSceCamera, and libSceDepth2, each exporting its
known NIDs via NotImplemented_nid_no_patch. Include debt documentation with
sysmodule IDs and (where available) orbital-derived signatures.
Add sceSystemServiceShowDisplaySafeAreaSettings as a silent success stub and
document it under Silent stubs.
AI-assisted: yes
A label recorded while a copied writer is listed went to the GPU and landed before the writer's CPU write-back ran at the batch's reap, so a title that rewrote the written region after polling the label had its bytes overwritten by the late write-back. The label now takes the drain path, which runs the write-back first and stores the label on the CPU.

send, sendto, sendmsg, recv, recvfrom and recvmsg failed with EOPNOTSUPP for
MSG_DONTWAIT on Windows, where FreeBSD 11.4 sosend_generic and
soreceive_generic make the one call non-blocking and fail with EWOULDBLOCK
when it would wait. Winsock has no per-call flag, so the call now asks WSAPoll
with a zero timeout whether the socket is ready and fails with EAGAIN when it
is not. The Windows branches of the socket tests that expected EOPNOTSUPP now
run the same checks as the other hosts.

Titles import sceNetCtlGetInfoV6, and a missing import stops them at
load. The checks that need no answer layout are implemented; every code
throws when the host has IPv6, since the layout of the answer is not
verified.
A title can fill one buffer and hand it to several ports in turn before
advancing the context. Reading the buffer only at push time gave every
port the contents set last, so the earlier ports played silence. Each
set now copies the grain, and a grain whose buffer is handed to another
port afterwards plays its copy. Buffers no other port is given are still
read at push time.
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.

The double Bessel functions follow the system libc.prx: FreeBSD msun
e_j0.c, e_j1.c and e_jn.c with every multiply-add the console fuses
done as one FMA, and the console's constant results for zero and
negative arguments of the second kind.

A --module-dir module that only the executable needs was initialized by
the Windows entry stub with no start arguments, so a later
sceKernelLoadStartModule with arguments found it started and its
module_start never saw them. Unity's mono-ps4.sprx keeps those
arguments for the plugins it loads. Such a module is now deferred like
any other runtime module: mapped at startup and started, with its
arguments, when the title loads it. Modules another guest module needs
are still started at startup, and Linux and macOS are unchanged.

rename and sceKernelRename resolved "dir/." to "dir" and renamed the directory. FreeBSD 11.4's lookup fails a last component of "." for DELETE and RENAME with EINVAL, for the source and the destination alike. Check the guest string before it is resolved: a last component of "." (also under trailing slashes) fails with EINVAL when its parent exists, ENOENT when it does not and ENOTDIR when it is not a directory.

Return the handle of an event flag this process created under the
given name, or ENOENT. Twispero opens the shell's
SceShellCoreUtilAppFocus flag at start-up and treats a failed open as
unknown focus.
stat, open, mkdir, rename and the other calls that resolve a guest path answered ENOENT (or EIO for rename) for a name longer than 255 bytes or a path of 1024 bytes or more, because the host path just did not exist. FreeBSD 11.4's namei fails a component above NAME_MAX and a path of MAXPATHLEN bytes with ENAMETOOLONG. Check both limits on the guest string before it is resolved; FilesystemError already maps the error to 63.
