The double Bessel functions follow the system libc.prx: FreeBSD msun
e_j0.c, e_j1.c and e_jn.c with every multiply-add the console fuses
done as one FMA, and the console's constant results for zero and
negative arguments of the second kind.

rename and sceKernelRename resolved "dir/." to "dir" and renamed the directory. FreeBSD 11.4's lookup fails a last component of "." for DELETE and RENAME with EINVAL, for the source and the destination alike. Check the guest string before it is resolved: a last component of "." (also under trailing slashes) fails with EINVAL when its parent exists, ENOENT when it does not and ENOTDIR when it is not a directory.

stat, open, mkdir, rename and the other calls that resolve a guest path answered ENOENT (or EIO for rename) for a name longer than 255 bytes or a path of 1024 bytes or more, because the host path just did not exist. FreeBSD 11.4's namei fails a component above NAME_MAX and a path of MAXPATHLEN bytes with ENAMETOOLONG. Check both limits on the guest string before it is resolved; FilesystemError already maps the error to 63.

getifaddrs listed only the host's IPv4 and IPv6 addresses, so the
per-interface AF_LINK entries FreeBSD's getifaddrs puts first were
missing, and with them the interface index, hardware address, MTU and
counters and every interface without an address.
On Linux each interface now starts with an AF_LINK entry, followed by
its addresses, as FreeBSD 11.4's getifaddrs orders them. Its address is
a sockaddr_dl with the host index, type, name and hardware address
(none for a loopback), sized as FreeBSD's if_attach sizes it. Its
ifa_data is a 152-byte FreeBSD if_data filled as if_data_copy fills it:
type, address and header length, link state, MTU, speed and the host's
packet, byte, error, drop and multicast counters from sysfs, or the
host list's 32-bit counters when sysfs cannot be read. Fields with no
host equivalent are 0 and listed in the debt entry. Windows is
unchanged.
The guest's second-kind Bessel functions return -inf and raise the divide-by-zero exception for x = +-0 (see e_jn.c), but the UCRT returns NaN for y1 and yn. Route x == +-0 through a shared helper, cover ynf(2, 0) in the guest math test, and note the special case in the libc technical debt.
MinGW libstdc++ up to GCC 16 does not treat a reparse point as a link in
std::filesystem::remove_all, so a host tree that holds a symlink is walked
through the link and never returns. Add RemoveTree, which removes the tree
itself on Windows, and use it where save data, app content and the shader
disk cache removed host trees. The libstdc++ fix is in GCC 17 (88856ad855ae).
Queue the stream in the table of the 8 standard stream
slots of Dinkumware's ios.cpp: the first free slot or the one
that already holds the stream, with a reference count per slot,
and the destructor suppresses the destruction of a standard
stream while its slot still has open references.
PPSA26578 (issue #7624) imports _ZSt26_Throw_bad_optional_accessv (NID
KwzEip7m6TM) from libc, and its bundled libc.prx does not export it,
causing the process to exit with 0xC0000139 (GetLastError: 127).
Implement std::bad_optional_access type record and vtable deriving from
std::exception, thrown through ThrowPlain, with what() returning
"bad_optional_access", and add unit test coverage in ExceptionRuntime.
In a payload process on a PS5 (firmware 12.70), the strtod and wcstod
of libSceLibcInternal.sprx keep the payload of a NAN(...) sequence,
read as FreeBSD 11's gdtoa hexnan reads it, under the quiet bit and
with the sign. strtof, wcstof, strtold and wcstold return the positive
default quiet NaN whatever the sign and the sequence, and consume a
sequence of letters, digits and underscores up to its closing
parenthesis. Here every NaN lost its payload, and strtof and strtold
kept the sign.
The model reproduces the 64 NaN inputs that p11, p14, p27 and p33
measured, including blanks and other characters inside the parentheses
and unterminated sequences, and the test now pins them. It also pins
two p71 cases measured through strtod: nan(1 2), and "nan( " followed
by NUL and ")". In hexnan, a blank after a payload digit, while a
32-bit word of the payload is still free, starts a blank skip that has
no NUL check, so when only blanks follow up to the terminating NUL the
console reads past it (p71); that case throws here. A blank right after
"nan(" is skipped with a NUL check, and the console stopped at the NUL
there.

In a payload process on a PS5 (firmware 12.70), jrand48 and mrand48
return the high 32 bits of the new 48-bit state zero-extended to the
64-bit long, as FreeBSD 11.0 does, so a result with bit 31 set comes
back between 0x80000000 and 0xFFFFFFFF. Here they sign-extended it, as
FreeBSD 11.1 and later do with an (int32_t) cast. lrand48 and nrand48
already matched the payload process. The tests now pin its results for
three seeds and the first six mrand48 values after srand48(1), compare
with the host as 32-bit values, and the debt entry records the
measurement.
