sceNetEpollCreate fails with EINVAL for a null name or non-zero flags,
sceNetResolverCreate and sceNetGetMacAddress for non-zero flags, and
sceNetResolverStartNtoa, before any other check, for a negative timeout
or retry count or a flag bit outside 0x10001, as prosper reads the
libSceNet module. The two accepted resolver flag bits are still ignored,
which the debt file now records.
Apply the firmware 13.42 module-probe report in PR #9506: all four DNS calls check initialization first; getters return EINVAL for null outputs or nonzero flags; setters reject flags before reading guest memory. Keep the checked input copy and document EFAULT as host safety, not firmware behavior. Use the current public Net.hpp declarations in the regression.
Rebased onto upstream e7e3e9c198. Ubuntu 24.04, GCC 13.3, Release: actual libc/libkernel/libSceNet libraries and both focused test executables built. guest_sce_net passes. A separate harness linked against those unmodified libraries passes initialization, errno, invalid flags, unreadable-input flag precedence, null clearing and unchanged-output checks. The full guest_net_dns_info test is blocked here: process_vm_readv is denied with EPERM by the execution environment. No full DNS regression pass is claimed. Public-header audit, conventions, test registration and whitespace checks pass.
The resolver still uses host DNS; IPv6 host-server discovery and firmware server-count behavior remain debt. Firmware evidence: https://github.com/boykopovar/AnyPS5/pull/9506#issuecomment-6390574180
AI-assisted: yes
Main's #10706 removes the local declarations at the top of libSceNet's
Export.cpp, where this branch had added __inet_pton and __inet_ntop.
libkernel's Api.hpp, which Export.cpp includes, now declares both, so the
merge takes main's side there.
After sceNetInit, the console's sceNetUsleep prints
"[LIBNET] usleep <count>" to standard output for a negative count
before failing with EINVAL, as a payload measured on firmware 13.60
(#9076). AnyPS5 failed without printing it.

main now starts libSceNetCtl initialized, so GuestNetCtl's checks before
sceNetCtlInit expect argument errors; the NpToolkit register, unregister
and check join them with the errors and result their IPv4 counterparts give.
Resolve the conflicts with main's libSceNetCtl initialization and
callback validation: the shared check now returns NOT_INITIALIZED before
sceNetCtlInit, as sceNetCtlCheckCallback does on main, so the NpToolkit
check does too; sceNetCtlTerm stays the no-op main measured; the NpToolkit
register and unregister keep their implementations with main's parameter
names. The NpToolkit entry joins main's rewritten debt file, and
GuestNetCtl checks the three before initialization.
FreeBSD 11.4's soreceive_generic waits in sbwait (sys/kern/uipc_socket.c,
uipc_sockbuf.c), whose msleep_sbt on so_rcv.sb_timeo returns EWOULDBLOCK
(35) for every socket type when SO_RCVTIMEO expires. On Windows the host
socket is non-blocking and native_transfer enforces the timeout itself,
but it reported WSAETIMEDOUT, which only datagram receives turned into
EAGAIN; a stream receive failed with ETIMEDOUT (60). A receive that
reaches the stored timeout now reports WSAEWOULDBLOCK, so every
receive returns EAGAIN, and a host WSAETIMEDOUT still maps to ETIMEDOUT.
A PS5 (firmware 13.60) allocates with any flag value, zero-fills only for
flag 2 and returns 64-byte aligned blocks. Record the measured behaviour of
sceNetGetIfName, sceNetGetRandom, sceNetGetSystemTime, sceNetMemoryFree and
sceNetUsleep, which already match the console, and keep only their open gaps.

sceNetCtlGetState reports DISCONNECTED as 0, while the callback receives
the DISCONNECTED event, 1, so the check aborted on a host with no
non-loopback address. Convert the state to its event before comparing.
