Measured on a PS5 (firmware 13.60):
- sceSslGetMemoryPoolStats returns 0x8095F007 for a null output, before
the id check, and 0x8095F006 for an unknown or terminated context,
zeroing the 32-byte output.
- sceHttp2GetMemoryPoolStats returns 0x817B1225 for a null output,
before the id check, and 0x817B1100 for an unknown or terminated
context, zeroing the 32-byte output.
- sceNetGetMemoryPoolStats checks the pool before the output, so an
unknown pool with a null output returns EBADF.

PPSA11386 imports it; on main it is one of the title's three missing
imports, with sceSslGetCaList and sceSslFreeCaList, and the title does not
call it during its start-up. The signature is unknown, so it is declared
without parameters and throws.

Winsock fails send, sendto and sendmsg on a socket shut down for writing
with WSAESHUTDOWN, which neither Windows error map handled, so libkernel
and libSceNet reported EIO. FreeBSD reports EPIPE there, and the Linux
maps already translate the host's EPIPE to 32. Map WSAESHUTDOWN to 32
in both.
sceHttp2GetMemoryPoolStats, sceSslGetMemoryPoolStats and
sceNetGetMemoryPoolStats threw. PPSA16064 (Minecraft Dungeons II,
Unreal Engine) queries all three while its HTTP module starts, and
aborted there.
Each library now records the pool size given at sceHttp2Init,
sceSslInit or sceNetPoolCreate and reports it with a peak and current
use of 0: the offline Http2 and Ssl models and the host-socket Net
library allocate nothing from these pools. The layouts follow the PS4
SDK's *MemoryPoolStats structures. Net returns EBADF for an unknown
pool and EINVAL for a null output, like its other pool calls; Http2 and
Ssl throw for both, as their error codes are unknown. Terminating a
context or destroying a pool forgets its size.
sceHttp2SetResolveRetry, which the title calls next, accepts and
ignores its value like the other Http2 settings. The four Http2
WebSocket exports the title imports are added as unimplemented.
guest_http2, guest_ssl and guest_sce_net check the reported sizes;
guest_sce_net also checks the null-output and unknown-pool errors.
The layout offsets the titles read are static_asserts, and guest_sce_net now
checks a canary past byte 384, distinct records, and an untouched buffer on the
EINVAL, RESOLVER_ENODNS and EBADF paths, as #1845's test did.

PS5VR (PPSA99177) stops at start-up on the unresolved import sT4nBQKUPqM;
Jelly5, Emby5 and Nuvio import it too. The call fills the 384-byte resolver
info with up to ten IPv4 records (32 bytes each, family at +16) and the record
counts at +320 and +324, from the same host lookup sceNetResolverStartNtoa
uses, now shared. Only flags 0 is implemented; other flags throw.

The host's EHOSTUNREACH was reported as ENETUNREACH (51); FreeBSD's
EHOSTUNREACH is 65, which libkernel's sockets already report. EADDRNOTAVAIL,
ENOBUFS, EISCONN, ENOTCONN and EACCES had no translation and became EIO;
they now map to 49, 55, 56, 57 and 13, as in libkernel/Socket/src/Udp.cpp.
guest_sce_net connects the connected client again and expects EISCONN
(0x80410138); before this change it received EIO.
A non-blocking sceNetConnect that cannot complete at once must fail with
EINPROGRESS (36, 0x80410124), as FreeBSD's connect does, and a repeated call
while it is pending with EALREADY (37). On Windows, Winsock reports the
first case as WSAEWOULDBLOCK, which was translated to EAGAIN (0x80410123); on
Linux, EINPROGRESS and EALREADY had no translation and became EIO
(0x80410105). Code that waits for the connection only when connect reports
EINPROGRESS treated both as a failed connection.
guest_sce_net connects a non-blocking socket to the loopback listener and
accepts 0 or EINPROGRESS; before this change it received EAGAIN on Windows.
libSceNet registers a socket poller with libkernel; select polls the requested descriptors through it until the timeout and rewrites the descriptor sets.
LEGO Horizon Adventures imports 19 functions that no library exports
and no open pull request adds, so it fails eager binding. They are
declared as throwing stubs. The two libSceAjmWVorbis imports have no
known name and are exported by NID from libSceAjm.native.

20 of the 31 NIDs have names in shadPS4's aerolib list. They are declared
under those names; POSIX sleep is implemented. The NpPartner001 and Psml
MFSR2 exports stay unnamed.

Every failing sceNet function returned -1 and left the code only in
sceNetErrnoLoc. The functions return the errno combined with
0x80410100 (SCE_NET_ERROR_*), as the resolver paths of this file
already do with RESOLVER_ENODNS and as shadPS4 and fpPS4 do for the
whole library. A title that compares the result with
SCE_NET_ERROR_EWOULDBLOCK saw a non-blocking receive without data as
an unknown failure.

sceNetSend and sceNetSendto called send and sendto without
MSG_NOSIGNAL, so a send on a connection the peer had closed raised
SIGPIPE and terminated the process. shadPS4 has sceNetSend pass
0x20000, FreeBSD's MSG_NOSIGNAL, down to sendto, so a title gets the
error back instead of a signal.
Pass MSG_NOSIGNAL on Linux and translate EPIPE, which fell through to
EIO.

Implement scePthreadGetschedparam and scePthreadSetschedparam on top of
the thread priority, POSIX utimes and fsync on top of sceKernelUtimes
and sceKernelFsync, and sceUserServiceGetAccessibilityZoomFollowFocus
like the other accessibility queries. Add the remaining imports of
PPSA12544 as unimplemented exports and record unknown NIDs and
signatures in the technical debt.

- Enhanced the network control library to check for host addresses and update connection states accordingly.
- Added support for socket operations including connect, listen, accept, send, and recv in the UDP and TCP socket implementations.
- Introduced error handling for various socket operations, ensuring proper feedback for unsupported actions.
- Created comprehensive tests for both TCP and UDP socket functionalities, validating the expected behavior of the network stack.
- Refactored existing code to improve clarity and maintainability, including the removal of unused functions and the addition of necessary error checks.
libSceNet: replace the always-fail stubs with a real offline network
stack. Sockets, epoll instances, memory pools and resolvers are tracked
in proper registries with create/destroy lifecycles; bind/listen/accept/
connect/send/recv/getsockopt/setsockopt/getsockname behave the way they
would on a console with no link up (bind and listen succeed locally,
connect/send fail with the errno a routeless host would give, blocking
calls such as accept/recv/epoll_wait return on close, abort or their
timeout). Infinite ("wait forever") timeouts are serviced in bounded
slices so a caller can never deadlock the process. Errno values match
the FreeBSD numbering the guest expects through sceNetErrnoLoc. Restored
sceNetGetsockopt and sceNetResolverStartAton (present upstream) using
the same registry-backed conventions as the rest of the rewrite.
libSceRudp: companion change giving the reliable-UDP library a genuine
context registry (init/create/bind/set-option/get-status) with
consistent error codes; connection attempts consistently fail since no
peer can ever be reached offline.
