A path whose directory part is a regular file, such as file/child, failed
with ENOENT in open, stat, lstat, access and unlink on Windows, where
FreeBSD 11.4 lookup fails it with ENOTDIR (vfs_cache_lookup, sys/kern/vfs_cache.c).
mkdir and rmdir already did. A not-found error of these calls now asks whether the
nearest existing ancestor is not a directory and reports ENOTDIR then.

listen on a connected stream socket failed with EISCONN, the Winsock error.
FreeBSD 11.4 solisten_proto_check fails a socket that is connected,
connecting or disconnecting with EINVAL. The guest listen now reports EINVAL
for the host's EISCONN, and the connect-listening test checks it.

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.

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.

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.

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.

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.

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.

In a payload process on a PS5 (firmware 12.70), getrlimit returns
0x200000 for RLIMIT_STACK, infinity for RLIMIT_RSS and RLIMIT_MEMLOCK,
and 1604 for RLIMIT_NPROC, each as both soft and hard limit. These four
threw here. Whether a title process reads the same limits is not
measured.
setrlimit reads getrlimit first, so it now accepts RLIMIT_STACK,
RLIMIT_RSS and RLIMIT_MEMLOCK when the values do not change, as the
payload process does. RLIMIT_NPROC throws: in the payload process
setting it to its current value succeeds, but getrlimit then reads 1443,
and the limit is not stored here. Any other change still throws. The
getrlimit and setrlimit debt entries also record the payload process's
RLIMIT_DATA and RLIMIT_NOFILE readings, its 12555 clamp of RLIMIT_NOFILE
and its RLIMIT_NPROC reading after a same-value set.
AI-assisted: yes

FreeBSD 11.4 rejects access mode 3 in kern_openat and
O_CREAT|O_EXCL|O_DIRECTORY in vn_open_cred before namei reads the path
or resolves the directory descriptor. open, _open and openat checked a
NULL or empty path first and returned EFAULT or ENOENT for those flags.
InvalidOpenFlags moves to FileFlags.hpp and runs first in all three.
kevent threw for EV_CLEAR on a socket or the read end of a pipe; Boost.Asio's kqueue reactor, among others, registers every socket that way. On Linux such a knote now watches its host descriptor through an edge watch. It is armed when added, on every later EV_ADD or EV_ENABLE while enabled, and by each host wakeup; when armed it is checked with the level-triggered readiness test and reported with the current data and EV_EOF, or disarmed if no longer ready, as kqueue_scan re-runs the filter; reporting it disarms it until the next edge. Waits block on the watch's epoll descriptor, so a socket that stays readable does not wake them. Windows and macOS still throw. GuestSockets::NativeDescriptor exposes the host socket behind a guest one for the watch.
FreeBSD activates an EV_CLEAR knote on each state change the object reports through KNOTE (sorwakeup, sowwakeup, pipeselwakeup), not on its level, so polling the level cannot tell an EV_CLEAR knote when to fire again. EdgeWatch::Watch registers the host descriptor with a private epoll instance in edge-triggered mode: every wakeup of the descriptor with a matching mask (data arriving, buffer space freed, a hang-up) queues one edge, which TakeEdge consumes, and the epoll descriptor itself is readable while an edge is pending, so a wait can block on it. Off Linux opening a watch throws.
WaitForDescriptors always handed the knote's own descriptor to the host wait. A filter that tracks readiness through a descriptor of its own, such as an edge watch, needs the wait to block on that descriptor instead, or a descriptor that stays ready keeps waking the wait. KernelFilter gets a waitDescriptor, and the filter's owner is held for the length of the wait so the descriptor cannot be closed under it.
