windows_dependency_diagnostics rewrites the fixture images right after the
diagnostic runner exits. The runner ends with an unhandled RaiseException of
STATUS_DLL_NOT_FOUND, and Windows fault handling keeps the exited process's
image files open for a short time after its handle is signaled: on Windows 11
22621 the Restart Manager names the exited runner as the holder and the file
opens 37 to 153 ms later. The rewrite then fails with ERROR_SHARING_VIOLATION,
and the final removal of the fixtures with access denied. Retry opening a
fixture while it fails with a sharing violation and the removal while it fails
with access denied, for at most 10 s each; every other failure still fails the
test at once.

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.

On Windows fsync and fdatasync of a pipe descriptor answered EBADF for the
read end and 0 for the write end. FreeBSD 11.4 kern_fsync reaches the
descriptor through getvnode, which fails a descriptor that is not a vnode
with EINVAL. NativeSync now refuses a pipe handle with EINVAL before it
commits.

flock on a descriptor that is not open threw a runtime_error from the failed
Windows lock call, ending the title. FreeBSD 11.4 sys_flock fails it with
EBADF (fget) and a descriptor that is not a vnode, such as a pipe, with
EOPNOTSUPP. The guest flock now checks the descriptor first, on Windows
through the OS handle and elsewhere through fstat.

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.
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.

FindTrailingRelativeJumpTable accepted a jump table after a function's
code only when padding followed it up to the end of the inspected range.
A PS4 function's table can end past its FDE, be padded to the next
16-byte boundary and be followed by more code before the next FDE. The
table is now accepted when padding reaches that boundary; it then ends
there, so the code after it is still analysed as code.

FreeBSD 11.4 kern_truncate returns EINVAL for a negative length before it
looks up the path, and getutimes rejects an out-of-range tv_usec before
namei in utimes and lutimes. The guest calls checked a NULL or empty path
first, so truncate(NULL, -1) and utimes("", {usec -1}) returned EFAULT or
ENOENT where FreeBSD returns EINVAL.

Since host imports group adjacent ranges into aligned blocks (#6457), an
import can span both 64 KiB blocks that an earlier import left unwatched
and the metadata of resident multisampled DCC targets.
ImportWatched with staysWatched took the whole import out of the write
watch when any part of it was not watched before. It now walks and
compares each run of watched blocks of the import on its own, and
unwatches only the blocks that were not watched or whose walk failed.
A resident DCC target took the generation of its metadata from a walk
of the metadata's pages alone. CPU stores to the rest of the metadata's
64 KiB block made before that walk were stamped later by the import's
walk, so the block read as written, and the import window marked the
metadata page as possibly stored over: the next draw refused the
target. The generations now come from a walk of the whole blocks.
agc_write_tracking and agc_driver_msaa_dcc_clear_* gain regression
tests for both.

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.

bind, listen, accept, connect, shutdown, getsockname, getsockopt, setsockopt, send, recv and the other calls that look up a guest socket answered EBADF for a descriptor that is open but not a socket, for example a pipe end. FreeBSD 11.4's getsock_cap fails these with ENOTSOCK and keeps EBADF for a closed or invalid descriptor.

The Windows build failed agc_performance_trace: ReplaceGzipFile made the
write fail by putting a directory at <name>.tmp, so the std::ios_base::failure
came out of libstdc++'s ofstream and could not unwind to the test's catch on
Windows.
The test now blocks the move instead, with a directory at the destination:
MoveFileExW (or rename) fails and ReplaceGzip throws std::system_error from
the driver's own code. ReplaceGzip also removes its temporary file when the
move fails, and the test checks that the blocked destination, the missing
temporary file and the other benchmark file are as expected.

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.

pr_overlap.py let a failed git or gh call escape as a bare
CalledProcessError traceback that names the command but drops the
error text, so a mistyped --base such as upstream/main (refs/heads/upstream/main
does not exist) read as an unexplained crash. The script now exits with
"pr_overlap: <command> failed with exit code N: <stderr>".
