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.
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.

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.

sceNpGetAccountId and sceNpSetGamePresenceOnline report NP as signed
out, and sceNpUnregisterPlusEventCallback returns 0 like the premium
form.

A domain program that picks one of its patch's control points from data
(Onimusha: Way of the Sword, PPSA27836, selects a corner with v_cmp and
v_cndmask before a buffer_load from the off-chip ring) was refused with
"the tessellation ring or LDS address is not affine in the control point
and relative patch". Computed indices were accepted only for hull LDS
reads.
- The address evaluator gives off-chip EvaluationInput reads the same
dynamic term as hull LDS reads, and a value read from the patch's own
ring or LDS no longer counts as depending on the relative patch index,
since the lowered read takes the patch implicitly.
- When the program also uses its relative patch index as data, the
index is replaced by the grouped patch instead of 0, which left a
computed read's address pointing into another patch. Such reads now
subtract their relative patch term, for hull and domain reads alike;
reads in programs that do not use the index as data keep their address.
- The computed offset must be a whole number of control points, and the
backend clamps the domain gl_in index to the last output control point
as it already does for hull reads.

The controller information reported 1920 by 943, the DualShock 4 height with
the DualSense pixel density, while the host controller's fingers were scaled to
1920 by 942 and the keyboard touch contacts sat on the 942 centre line. A title
that maps touch coordinates through the reported resolution lost the lower part
of the touchpad. The width and height now live beside the pad state and all
three places use them.
sceMoveOpen returned a new handle for any user, type and index, although
the console's result for a user other than the initial user and for a
type and index that are already open is not known. Both now throw, as
libSceHmd2 does for another user. Record which shadPS4 behaviour the
handle and open checks add to.

MCOMMIT becomes STC plus NOP padding and RDPRU goes through a
runtime-checked stub returning the host TSC for MPERF/APERF while
other selectors yield zero, with converter and execution tests.
docs/dev/debt/relinker.md records the new lowering and its unverified
assumptions.
