Read the clock of a libkernel condition attribute, returning
SCE_KERNEL_ERROR_EINVAL for a null or destroyed attribute as
scePthreadCondattrSetclock does, after FreeBSD 11.4 libthr's
_pthread_condattr_getclock. A null clock pointer throws.
The EINVAL for a descriptor without a vnode now applies only to a pipe or socket. A character device is a vnode on FreeBSD, so getvnode succeeds and change_dir fails with ENOTDIR; File::IsCharacterDevice keeps that answer for the host character devices (a tty, NUL or /dev/null) and the guest random device. guest_kernel_sys pins it with /dev/random.

FreeBSD 11.4's sys_fchdir resolves the descriptor with getvnode, which fails with EINVAL for a descriptor that has no vnode; only a vnode that is not a directory gives ENOTDIR from change_dir. fchdir returned ENOTDIR for a pipe or socket. A descriptor that is neither a vnode nor a random device now gets EINVAL; the debt entry records the order of the three errors.

Forward scePthreadBarrier*, scePthreadBarrierattr*, scePthreadGetcpuclockid,
scePthreadGetconcurrency and sceKernelMsync to libkernel's POSIX
implementations and return POSIX errors as SCE kernel errors.

The PS5 3.20 export lists have ktimer_* in libkernel as well as
libkernel_sys, and on Windows a libkernel import never reaches
libkernel_sys. The implementation moves unchanged to
libkernel/Time/Ktimer.cpp.
Resolves the conflict with #8522 in link_nid_postfix: keep its ENOTDIR
return for a destination below a regular file and the Windows
symbolic-link follow after it.

link_nid_postfix decided whether to follow the source with
std::filesystem::is_symlink, which MinGW-w64's libstdc++ never reports for
a Windows symbolic link, so on Windows link made a hard link to the link
itself. Follow a reparse-point source to its final path with
GetFinalPathNameByHandleW instead, and run the link-through-a-link case of
guest_kernel_sys on Windows too.

Write the low 32 bits of the SDK version field at offset 0x10 of the
title's process parameters and return EINVAL (0x80020016) for a null
output, following shadPS4.

Both were missing from libkernel.prx, so a title importing either
(dYv-+If2GPk, RRnSj8h8VR4) failed to load. They take a relative timeout
in microseconds and are scePthreadRwlockTimedrdlock and
scePthreadRwlockTimedwrlock with POSIX error numbers; a zero lock is
initialized as by pthread_rwlock_rdlock. The signature comes from
shadPS4, which registers one function for each NID and its
scePthreadRwlockTimed* twin; FreeBSD 11.4 has no such calls. The throwing
libkernel_sys copies are removed, as an export may live in one library
only. Recorded in the libkernel debt file.

lchmod forwards to fchmodat with AT_FDCWD and AT_SYMLINK_NOFOLLOW, as
FreeBSD 11.4's sys_lchmod does. On Linux and Windows, which cannot change
the mode of a symbolic link itself, a symbolic link throws instead of
succeeding without a change.
fstat was a NotImplemented stub in libkernel_sys. It now calls libkernel's
_fstat, as fstatfs already calls _fstatfs, so it reports the same status,
EFAULT for a null buffer and EBADF for a descriptor that is not open.
FreeBSD lookup() refuses "." and ".." as the last component of a DELETE
lookup with EINVAL (sys/kern/vfs_lookup.c:750-754 and 823-826), before the
unlink and rmdir checks run. unlink and sceKernelUnlink answered EPERM,
rmdir and sceKernelRmdir answered ENOTEMPTY for "..", and unlinkat without
AT_REMOVEDIR answered EPERM. Reuse the RenameDot check added for rename, so a
missing or non-directory parent still reports ENOENT or ENOTDIR first.

FreeBSD 11.4 kern_symlinkat copies the target with copyinstr(path1, ..., MAXPATHLEN)
(sys/kern/vfs_syscalls.c:1490), so a target of 1024 bytes or more fails with
ENAMETOOLONG before the link name is looked up. symlink_nid_postfix had no length
check on the target.

A path whose directory part is a regular file, such as file/child, failed
with ENOENT in readlink and readlinkat on Windows, where FreeBSD 11.4 fails
it with ENOTDIR (vfs_cache_lookup, sys/kern/vfs_cache.c). The not-found
error now checks whether the nearest existing ancestor is not a directory,
as was previously done for chmod, truncate, utimes, rename, remove, chdir,
opendir, and fopen.

FreeBSD 11.4 kern_readlinkat returns EINVAL for a count above IOSIZE_MAX
before namei looks at the path. readlink and readlinkat checked a NULL or
empty path first, so readlink(NULL, buf, SIZE_MAX) returned EFAULT and
readlink("", buf, SIZE_MAX) returned ENOENT where FreeBSD returns EINVAL.

lstat and readlink threw NotImplemented for every Windows reparse point
other than a symbolic link or a drive junction. A tag without the name
surrogate bit (cloud files, deduplication) does not stand for another path,
so lstat now answers as stat does and readlink returns EINVAL, as FreeBSD
does for a file that is not a link and as CPython's os.lstat and os.readlink
do (bpo-37834). A name surrogate that is neither a symbolic link nor a
junction (a mounted volume, a WSL link) is reported as the reparse point
itself with the mode of its attributes, and readlink returns EINVAL.
The tests set reparse tags with FSCTL_SET_REPARSE_POINT, one without the
name surrogate bit and one with it. A compact /exe (WOF) file cannot serve
as the fixture: on Windows 11 24H2 the WOF filter hides the reparse point
from GetFileAttributesW and FileAttributeTagInfo alike. Windows refuses
every open of an unhandled tag without FILE_FLAG_OPEN_REPARSE_POINT, so the
test requires lstat to agree with stat rather than to succeed.
mashingaan's boykopovar/AnyPS5#6447 returned EINVAL for other reparse
points without the tag check.
