Port FreeBSD 11 lib/libc/stdlib/random.c (freebsd-src 4ab2e064): the
additive feedback generator with the default 128-byte TYPE_3 table,
good_rand seeding, state sizes rounded down to 8, 32, 64, 128 or 256
bytes, setstate returning the previous state, and initstate returning
null below 8 bytes without setting errno. Calls are serialised by one
lock; a null state throws.
The import audit of the homebrew catalog on main 262c0316 lists them as
absent libSceLibcInternal imports:
- random: PPSA74126 Stremio Plus, PPSA85300 VLC, PPSA99169 RetroArch,
PPSA99177 PS5VR, PPSA99420 PS5MC, PPSA99505 Jelly5, PPSA99515 Emby5,
PPSA99810 PSBox Cloud Gaming
- srandom: PPSA85300, PPSA99169, PPSA99420, PPSA99810
- initstate, setstate: PPSA99177, PPSA99420, PPSA99505, PPSA99515

The POSIX alias takes (attr, int), returns EINVAL (22) for a null or
uninitialized attribute like the other pthread_attr setters, and
stores the value through scePthreadAttrSetsolosched, returning its
result in errno form. The signature and the stored int follow the SCE
twin in KytyPS5 and sharpemu; PS5PCEM implements the alias the same
way. The value is not applied to scheduling, recorded in TechnicalDebt.
Returnal (PPSA01285 v03.000.005) stops on it after eager binding
(#2872, #1155):
what(): pthread_attr_setsolosched_np_nid_postfix not implemented
LEGO Horizon Adventures (PPSA14632, #734) and Palworld (PPSA23126,
#2598) import it.

Use the upstream CMASK implementation and remove the import requirement from image clears. Propagate storage-image creation failures. Test repeated clears, copied write-back, and failure without changing guest data.
AI-assisted: yes.
A wait on an equeue that holds socket events now blocks in poll/WSAPoll on
those sockets plus a per-thread loopback wake socket, instead of rechecking
every millisecond. Adding, triggering or deleting an event and closing the
equeue wake the blocked waiters. Closing a socket removes its read and write
events, as on FreeBSD. A read event also reports EV_EOF once the peer has
shut down its sending side.
sceKernelAddReadEvent/DeleteReadEvent and sceKernelAddWriteEvent/
DeleteWriteEvent register EVFILT_READ and EVFILT_WRITE events on guest
sockets. The equeue polls the host socket for readiness on each wait
and reports the readable byte count or the send buffer size in data,
with EV_EOF on hang-up or error.
pthread_cond_wait and pthread_cond_timedwait, and their sce counterparts, threw a
host exception when the mutex was unlocked, locked by another thread, or not yet
initialized, and dereferenced the adaptive static initializer. FreeBSD returns
EPERM for these (EINVAL for a destroyed mutex) before touching the condition.

The elected lane's inner spin loop never ended on Mesa ANV with the LDS in
a storage buffer. It now tries once and the outer loop elects again; the
update is unchanged.
