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.
Main extends the libkernel debt entry on libSceNet sockets with poll and
fcntl, where this branch adds getsockopt to the same entry; the merge keeps
both.
Main's #10706 declares the libSceNet functions this branch implements, and libkernel's sysctl, __inet_pton and __inet_ntop, in the libraries' public headers, so this branch's local declarations of them in GuestSceNet.cpp and libSceNet's Export.cpp go.
Main's #10706 declares getsockopt_nid_postfix and sceNetGetsockopt in the libraries' public headers, so this branch's local declarations of them in GuestSceNet.cpp and libSceNet's Export.cpp go.
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.
sceNetConfigGetDefaultRoute threw. It now writes the IPv4 gateway of the
host interface that libSceNetCtl's sceNetCtlGetInfo already describes as
DEFAULT_ROUTE, in network byte order, the order sceNetInetPton writes an
AF_INET address in, and returns 0. libSceNetCtl exports
NetCtlHostIpv4Gateway_nid_no_patch for it, next to the DNS helper
sceNetGetDnsInfo uses. Without a gateway, or for a null pointer, it
still throws: the console's answer for a missing route is not measured.
Tested: guest_sce_net_tests, after sceNetCtlInit, prints the gateway
with sceNetInetNtop and compares it with sceNetCtlGetInfo's
DEFAULT_ROUTE text (192.0.2.1 on this host); a null pointer throws.
On a host without a default route the case checks that the call
throws and leaves the output untouched.
sceNetInetNtopWithScopeId and sceNetInetPtonWithScopeId threw. They now
handle AF_INET6 text with an RFC 4007 numeric zone (fe80::1%2): the
address part goes through sceNetInetNtop and sceNetInetPton, so it
follows the FreeBSD inet text rules, and the zone is printed and parsed
as FreeBSD 11.4's getnameinfo (NI_NUMERICSCOPE) and getaddrinfo do. A
zero scope ID prints the address alone and text without a zone parses
to scope ID 0. An empty zone, one above 2^32 - 1, or an invalid address
part returns 0 and leaves both outputs untouched; a buffer too small
for the scoped text gives ENOSPC.
A zone given as an interface name, and AF_INET, still throw: the tree
has no mapping from interface names to the console's interface indexes
and no answer for an IPv4 zone. The debt file says so.
Tested: guest_sce_net_tests round-trips fe80::1%2 (same address bytes
as fe80::1, scope ID 2) and ff02::1%4294967295, checks the exact
buffer size and ENOSPC one byte short, the unscoped forms, four
rejected texts with untouched outputs, EINVAL for null pointers, and
that an interface-name zone and AF_INET throw.
sceNetSysctl threw. Its restored argument list is FreeBSD's sysctl(3)
(name, name length, old value and size, new value and size), so it now
calls libkernel's sysctl. It answers exactly the MIBs libkernel models,
and a failure is returned as the library's other calls return one
(0x80410100 | errno, with the errno set).
Tested: guest_sce_net_tests reads hw.pagesize (6.7) through both
sysctl and sceNetSysctl and gets the same value and size, including a
size-only query. A one-level name gives EINVAL, a null name EFAULT, a
write EPERM and a one-byte buffer ENOMEM, each as 0x804101xx with the
errno set.
sceNetSocketInternal, sceNetGetsockoptEx and sceNetSetsockoptEx threw.
Their argument lists, restored with the rest of the firmware exports in
4d6942f1e, are the same as sceNetSocket, sceNetGetsockopt and
sceNetSetsockopt, so they now call those. Nothing in the tree records
how the console tells the entry points apart (for example by the
calling process); the debt file says so.
Tested: guest_sce_net_tests creates a datagram socket through
sceNetSocketInternal, sets SO_REUSEADDR and SO_RCVTIMEO through
sceNetSetsockoptEx and reads them back through sceNetGetsockoptEx and
sceNetGetsockopt with the same values. On a closed socket and on -1,
and for an unsupported family and type, each Ex/Internal call returns
the same error and errno as its public twin.
Base for the libSceNet Ex/Internal forwards: upstream main 94fbb8cea with fix/libscenet-inet-text-rules (ef49574f5) and fix/libkernel-getsockopt-net-sockets (aea804d9f).
