The signature, int sceGameLiveStreamingEnableLiveStreaming(const bool
isEnableLiveStreaming), follows Orbital and fpPS4. No broadcast is ever
on air, so both values succeed and change nothing. A call outside
sceGameLiveStreamingInitialize and sceGameLiveStreamingTerminate throws,
as the console's error for it is unknown.
Monopoly Plus (CUSA03312) stopped at this call after its language screen.

A bundled module that names a console file dependency (.sprx, .suprx,
.debug_prx) imports by symbol name, as homebrew built with the
ps5-payload-dev SDK does. Bind those imports to the NID of the name,
except names another bundled module or the executable exports, and name
the module's host dependencies with the .prx library of the same stem.
soreceive_generic returns 0 for a socket whose receive side is shut and for a
zero-length receive on a connected stream socket (ENOTCONN when it is not
connected), without waiting. Winsock fails the first with WSAESHUTDOWN, which
reached the guest as EPIPE, and blocks the second until data arrives. recv and
recvfrom now answer both themselves.

Both one-shots threw. They run Init, Update and Final through
libSceLibreSsl's MD5_* and SHA1_*, which libSceLibreSsl3 now links,
and return the digest buffer. A null digest buffer throws, since
LibreSSL up to 3.8 hashes into a static buffer and later versions do
not check it.

MD4, MD5, SHA1, SHA224, SHA256, SHA384 and SHA512 Init/Update/Final and
the SHA256 one-shot threw. They now hash as LibreSSL does, on the
caller's MD4_CTX, MD5_CTX, SHA_CTX, SHA256_CTX and SHA512_CTX laid out as
in LibreSSL's md4.h, md5.h and sha.h, so a context copied or inspected
by the title stays valid: the bit count in Nl/Nh, the partial block in
data with its length in num, and md_len selecting the truncated digest.
Final pads and clears the buffer as LibreSSL's sources do.
Cases that differ between LibreSSL versions throw: SHA256 with a null
digest buffer and SHA512_Final with the SHA-512/224 or SHA-512/256
length. The test checks the RFC 1320, RFC 1321 and FIPS 180 vectors over
several chunk sizes, the context fields, copied contexts and those
cases.

Homebrew built with the ps5-payload-dev SDK names its system
libraries with .sprx and imports by symbol name, while the libraries
in libs/ are .prx files that export NIDs. On Linux such an executable
converted but stopped at load time on the first .sprx dependency and,
once that was found, on the first symbol name.
The Linux patcher now loads a dependency named with .sprx, .suprx or
.debug_prx as the .prx library of the same stem. In an executable that
names such a dependency, an import without a module that is named by
symbol gets the NID of that name. A name that a bundled module exports
still binds to that module. There is no lookup by the name as written,
because the host loader also searches the host C library. Other
executables keep their unqualified imports as written.
On Linux sceKernelGetdirentries copied the host d_type, so a directory under app0 that is a host symlink was listed as a link, and a title that only descends into directory entries skipped it. Inside the app0 tree, report a symlink (or an entry of unknown type) as the type of its target; links elsewhere, and dangling links, stay links.
StorageTexture throws when none of an image's guest pages is committed.
Three titles reach it intermittently in runs of a few minutes, on AMD and
NVIDIA, and the log names no address. The entry states the gap and that
the console behavior for such a descriptor is not known.

Two unwind queries a title makes went wrong on macOS, so a C++ exception the title would catch ended the process instead: God of War Sons of Sparta (PPSA28997) stops on an IL2CPP exception it normally handles.
- sceKernelGetModuleInfoForUnwind found a relinked image and its PT_GNU_EH_FRAME header but left eh_frame_addr and eh_frame_size at zero, so the title's unwinder found no FDE for its own frame. The tables are now read with EhFrame::ReadTables over the image's load segments, as ModuleInfo does on Linux, and eh_frame_size includes the zero terminator, as on Linux.
- sceSysmoduleGetModuleInfoForUnwind read /proc/self/maps outside Windows and threw on every call on macOS. It now answers from mach_vm_region, with the image path from dladdr, as the Linux branch answers from the mapping.
guest_unwind_module_info now runs on macOS: the test executable carries the __APS5DATA,__meta program headers that the macOS dl_iterate_phdr reads from a relinked image. guest_sysmodule checks the macOS answers against mach_vm_region.

v_cvt_pk_u8_f32 rounds its source in the f32 round mode of FLOAT_MODE
and flushes a denormal source when f32 denormals are flushed, as
measured on RDNA2 (gfx1030). It was always rounded to nearest even, so
the three directed modes gave wrong bytes for non-integer sources.

A custom submixer rack now accepts the Gain module (0x15). Its voice
parameter 0x40001500 | module index sets one linear level per channel
(37 levels, default 0), and each grain multiplies the voice's samples
by a level that ramps linearly from the previous one to the new one,
following fma-rc's reading of the PS5 12.70 module (#8039). Gain on a
custom sampler rack, whose parameter index is offset, still throws, as
do levels outside -32 to 32.

Since #8162 a --module-dir module that the executable needs is deferred
on Windows: the entry stub maps it and the title starts it with
sceKernelLoadStartModule. A module the executable imports from but the
title never loads gets no module_start and no initializers, silently.
The entry stub now prints one line at startup for each deferred guest
module that an import of the executable names. Guest module bytes are
unchanged.

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.

When the startup probe chose the hardware f32 flush, every module declared
DenormFlushToZero 32, also shaders whose FLOAT_MODE keeps f32 denormals
(f32 denormal field 1, 2 or 3), so the device flushed what they keep and
DenormPreserve 32 was never declared. The hardware flush now applies to
shaders that flush f32 denormals (field 0, or no float mode); the others
declare DenormPreserve 32 where the device supports it.

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.

Follow FreeBSD 11.4 sys_setresuid and sys_setresgid (sys/kern/kern_prot.c):
accept real, effective, and saved user and group IDs for the guest process,
which is assumed to run as root with IDs 0. Setting an ID to 0 or -1 (unchanged)
is accepted without changing credentials and returns 0; any other value throws.
Cover both in guest_credentials test and update libkernel debt documentation.
