A payload process on a PS5 (firmware 13.60) parsed 124 status lines and
lengths. It checks lineLen only for its minimum of 8 and for the three
code digits, reads the version and its separators past it, and finds the
line feed up to and including the byte at lineLen, so a length that
stops right before the line feed still parses. When the version ends
past lineLen the unsigned subtractions wrap and the search continues
until a line feed.

After the argument checks, shadPS4 looks the request up and returns
REQUEST_NOT_FOUND for one that was never created or was deleted. The
library already tracks live requests for sceNpSetTimeout.

A payload process on a PS5 (firmware 13.60) parsed, built and merged
several hundred URIs. sceHttpUriParse cuts the hostname at the first
byte that cannot be in it and starts the path there instead of failing,
takes the userinfo up to the first '@', accepts a port up to 65536 that
ends at '/' or the end, and gives https... schemes 443 and http...
schemes 80. It sweeps the path as sceHttpUriSweepPath does but sizes the
pool for the unswept path, and leaves require alone when the pool is too
small. sceHttpUriBuild writes IPv6 hostnames without brackets.

Implement sceNpWebApi2AddWebTraceTag with the (int64_t request_id, const char* value) signature from shadPS4. Validates that value is not null, accepts any request id, and acts as a silent stub matching the other offline request functions.
sceAjmDecWVorbisCreateHeaderPacket checks its 0x48-byte parameter as the
PS5 module does and writes a five-entry length table, a Vorbis
identification header from the parameters, an empty comment header and
the setup packet.

The PS5 module's sceAudioOut2LoTerminate stops the low-latency service
and returns 0 whether or not it runs; sceAudioOut2LoInit starts no
service here. sceAudioOut2InitializeEx stores its argument and runs
sceAudioOut2Initialize.

The PS5 module returns 0x80A00002 for a null pointer and otherwise
clears the 0x134C-byte program info before filling it from the system
service. Nothing is broadcast here, so the info stays zero.

A read of memory inside a stale D32 Z_X depth plane (FlushDepthPlanes) stored
the whole plane: a copy of the depth image into the mirror, MarkWholeWritten
and a write-back of every byte. In Super Meat Boy 3D (#8840) a read-only
buffer ending about 3 KiB inside a stale 3840x2160 plane makes
ShaderResources::Revalidate flush ~1000 times per 5 s, each one moving
31.9 MiB, bound by transfer bandwidth.
A depth surface now tracks its plane as 64 KiB units, each one 128x128 tile
of the mirror's block units: a stale bit and a write generation per unit
replace memoryStale and the plane-wide syncedGeneration.
- FlushDepthPlanes stores only the stale units the range overlaps: the depth
to mirror copy takes one region per unit rectangle (UnitRects, from the
mirror's slice windows), the mirror marks just those units written
(MarkUnitsWritten) and the write-back covers their hull. The other units
stay stale and the plane stays registered. Stale bits are cleared only
after the copy was recorded, and the stored units' generations advance
only when FlushPending stored them. A depth fast clear still pending at
the store rewrites the whole image, so it makes every unit stale first.
- SyncFromMemory copies from the mirror only the units the guest wrote since
their own generation (one ChangedBlocks scan; untracked memory counts as
unwritten, as WrittenSince did), so a guest write into one unit no longer
replaces GPU depth that is still unstored in the others.
- Flushes followed by a retire keep the whole-plane store: the color target
flush in Draw and a written storage view (DepthPlaneScope::Whole). The
retire of an overwritten surface in DepthSurfaceTexture first stores its
remaining stale units the guest did not write.
- A mirror without block units (APS5_NO_BLOCK_TRACKING, unaligned base)
falls back to the whole-plane copy, and APS5_DEPTH_PLANE_WHOLE_STORE=1
tracks the plane as one unit, the previous behaviour.
- DepthPlaneStoreCounts reports stores, units and bytes stored.

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.
