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.

d3011ae11 made dup and dup2 of a Windows directory descriptor share
its DirectoryState, as FreeBSD's kern_dup shares the open file, and
removed the clause; a later merge of the entry brought it back.
GuestDirectoryRewind covers both calls.
Linux's udp_sendmsg refuses port 0 with EINVAL, so a send that FreeBSD
accepts (the socket is bound to a specific address and port and the
destination is not INADDR_ANY or INADDR_BROADCAST) failed there. Nothing can
receive on port 0, so the call now returns the length itself on every host.

udp_output hands the destination to in_pcbconnect_setup unless the socket is
bound to a specific address and port and the destination is neither
INADDR_ANY nor INADDR_BROADCAST, and in_pcbconnect_setup fails port 0 with
EADDRNOTAVAIL. The send went to the host, which accepted it. sendto, and
sendmsg through it, now fails the same way for an AF_INET datagram socket
that is not connected. connect to port 0 already did.

soreceive_generic keeps a MSG_WAITALL receive on a stream socket waiting until
the buffer is full, the peer closes or an error occurs. The three calls failed
every flag but MSG_PEEK and MSG_DONTWAIT with EOPNOTSUPP. A stream socket now
passes the flag to the host receive; a datagram socket ignores it, as a record
is delivered whole.

In a payload process on a PS5 (firmware 12.70), sysctlbyname returns -1
with ENOENT for thirteen names that threw here, and leaves the buffer and
the length alone, for a read, a size query, a null length and a null
buffer with a null length. sysctl does the same for the fixed MIBs of
seven of them. sysctlnametomib gives those seven MIBs and returns ENOENT
for hw.cacheline_size and hw.usermem, which threw too.
machdep.cacheline_size already returned ENOENT and is now tested with
the others. A write to the new names and MIBs throws, as the console's
answer to a write was not tried. The hw.realmem and vm.overcommit debt
entries now say that a payload process gets ENOENT for them as well.

kevent threw for EVFILT_WRITE on any descriptor that is not a socket. On the write end of a pipe it now follows FreeBSD 11's filt_pipewrite: data is the free buffer space, and once the read end is closed the event reports EV_EOF with data 0. Adding the event after the read end is closed fails with EPIPE, as in pipe_kqfilter. EVFILT_WRITE on the read end still throws, because FreeBSD's pipe ends are bidirectional and host pipes are not.
On Windows, sceKernelPwrite, pwrite, sceKernelPwritev, pwritev and the AIO
write commands wrote at the given offset on a descriptor opened with
O_APPEND. FreeBSD's vn_write sets IO_APPEND for an O_APPEND regular file
whether or not an offset is given, the filesystem then writes at the end of
the file, and the file offset is left unchanged. Write at Windows'
end-of-file offset in that case, and gather a multi-buffer pwritev into one
write as writev already does.
Host logging opens its own FILE on the saved descriptor. The guest FILE stays on the replaced descriptor, so guest printf, puts and fprintf still reach the pipe.
Follow FreeBSD 11's do_sem_wait and do_sem_wake (COMPAT_FREEBSD9/10) on
a struct _usem: a wait sets _has_waiters, returns at once while _count
is non-zero and otherwise sleeps on the semaphore's queue; a wake clears
_has_waiters when one waiter is left and releases one waiter.

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.

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.

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.
bind, connect and sendto answered EFAULT for an address length below 2 and EAFNOSUPPORT for an AF_INET address below 16 or an AF_INET6 address below 28 bytes. FreeBSD 11.4's getsockaddr fails a length below 2 with EINVAL and above SOCK_MAXADDRLEN (255) with ENAMETOOLONG, and the protocols compare the length with sizeof(struct sockaddr_in) or sockaddr_in6 and fail with EINVAL.

PS4 titles import both and do not load without them; every call throws and
the debt files list them.

The entry before it still says sceKernelAddReadEvent and
sceKernelAddWriteEvent take only guest sockets. The pipe entry now says it
is the exception, without editing that entry, which an open change to the
shared-memory entry next to it would conflict with.

The guest socket layer relies on a few Linux calls:
- The equeue wait uses poll with the timeout rounded up to a millisecond;
macOS has no ppoll.
- A readable stream socket whose peer closed is reported with POLLHUP by
peeking one byte; macOS has no POLLRDHUP.
- FIONREAD on a datagram socket, and the byte count that fstat and kevent
report for it, is SO_NREAD, the size of the next datagram; macOS adds the
source address to FIONREAD.
- socketpair throws for SOCK_SEQPACKET, which has no AF_UNIX pair on macOS.
- gethostbyname replaces gethostbyname_r, which macOS lacks.
The UDP test sends on its connected socket without an address, as #7475
does, because macOS, like FreeBSD, fails sendto with an address on a
connected socket with EISCONN. The log test uses a datagram pair with
enlarged buffers instead of SOCK_SEQPACKET.
