Debt entries name the titles they were measured on. Use the title ID, or "a retail title" where the sentence needs no identification. No technical content changes.
siginterrupt is a libSceLibcInternal export (the public SDK's stub table has it there, not in the
kernel tables) and FreeBSD 11.4's lib/libc/gen/siginterrupt.c reads the signal's disposition,
sets or clears the signal's bit in _sigintr and SA_RESTART, and installs the disposition again.
libc cannot call libkernel, so, as the pthread hooks do, libc keeps a registered sigaction and
the address of the _sigintr set, and libkernel registers both from a static initializer when it
loads. A call before that throws; the set is written without libkernel's registration lock, as
FreeBSD's libc does. Builds on #8866, which adds the set.

The public SDK's libkernel, libkernel_sys and libkernel_web stub tables declare _sigintr, the
sigset_t that FreeBSD's libc shares between signal and siginterrupt, and no built library
provided it (#8846). libkernel now exports the 16-byte object, zero at start, and signal records
a handler with SA_RESTART unless its signal is in the set, as lib/libc/gen/signal.c does.
siginterrupt, which fills the set, is a libSceLibcInternal export; libc does not link libkernel
and cannot reach the dispositions, so it stays out and a debt entry for signal says so.

pthread_kill(thread, 0) returned 0 for every handle other than the caller's before it asked whether the thread was still alive. FreeBSD's _pthread_kill looks the thread up with _thr_find_thread before it checks for signal 0, so the call answers ESRCH for a thread that has ended or was never a thread. The liveness check now runs before the signal 0 shortcut; the calling thread still answers 0.

Keep main's WaitOnKey helpers from #8304 and build the measured
sceKernelSyncOnAddressWait results on them: the wait's ready check now
records whether the value differed, and Wake returns the waiters woken.

Since #8512 a raise redirects a target running host code once 50 ms have
passed since the raise began. A target inside a system call that is not a
wait, such as the NtWriteFile of an fwrite that holds its stream lock, can
stay there longer; the redirect then ran the handler with the lock held.
SONIC SUPERSTARS froze at frame 67 again on main this way, with its GC
raise delivered at ntdll!ZwWriteFile+20.
A target stopped right after a syscall instruction in ntdll now restarts
the 50 ms host-code window, so the raise keeps sampling until the call
returns and the target leaves host code, bounded by the 1 s retry limit.
guest_raise_in_system_call holds a writer in NtWriteFile on a slowly
drained pipe; it times out on main and passes with this change.

kevent threw NotImplemented for EVFILT_WRITE with NOTE_LOWAT above 1 on a socket, although the socket readiness check already reports free send-buffer space (SO_SNDBUF less SIOCOUTQ on Linux). The write event now fires once that space reaches the mark, as FreeBSD 11's filt_sowrite compares sbspace with kn_sdata, and stays silent while the space is below it. The debt entry no longer says a write mark is limited to 1. Reference: https://github.com/freebsd/freebsd-src/blob/release/11.0.0/sys/kern/uipc_socket.c
FreeBSD 11.4 kern_mprotect masks the argument with VM_PROT_ALL instead of
refusing it (sys/vm/vm_mmap.c:613). sceKernelMprotect already does this
since #5770; the POSIX mprotect export still failed with EINVAL.

FreeBSD 11's kern_pipe opens both ends with FREAD | FWRITE, so F_GETFL
reports O_RDWR on each. The host pipe ends are one-way, so the access
mode came back as O_RDONLY and O_WRONLY. Descriptors made by pipe() are
now marked in the guest descriptor table, the mark follows dup, dup2 and
F_DUPFD, and F_GETFL reports O_RDWR for them.
lstat and readlink threw NotImplemented for every Windows reparse point
other than a symbolic link or a drive junction. A tag without the name
surrogate bit (cloud files, deduplication) does not stand for another path,
so lstat now answers as stat does and readlink returns EINVAL, as FreeBSD
does for a file that is not a link and as CPython's os.lstat and os.readlink
do (bpo-37834). A name surrogate that is neither a symbolic link nor a
junction (a mounted volume, a WSL link) is reported as the reparse point
itself with the mode of its attributes, and readlink returns EINVAL.
The tests set reparse tags with FSCTL_SET_REPARSE_POINT, one without the
name surrogate bit and one with it. A compact /exe (WOF) file cannot serve
as the fixture: on Windows 11 24H2 the WOF filter hides the reparse point
from GetFileAttributesW and FileAttributeTagInfo alike. Windows refuses
every open of an unhandled tag without FILE_FLAG_OPEN_REPARSE_POINT, so the
test requires lstat to agree with stat rather than to succeed.
mashingaan's boykopovar/AnyPS5#6447 returned EINVAL for other reparse
points without the tag check.

d3011ae11 made dup and dup2 of a Windows directory descriptor share
its DirectoryState, as FreeBSD's kern_dup shares the open file, and
removed the clause; a later merge of the entry brought it back.
GuestDirectoryRewind covers both calls.
Linux's udp_sendmsg refuses port 0 with EINVAL, so a send that FreeBSD
accepts (the socket is bound to a specific address and port and the
destination is not INADDR_ANY or INADDR_BROADCAST) failed there. Nothing can
receive on port 0, so the call now returns the length itself on every host.

udp_output hands the destination to in_pcbconnect_setup unless the socket is
bound to a specific address and port and the destination is neither
INADDR_ANY nor INADDR_BROADCAST, and in_pcbconnect_setup fails port 0 with
EADDRNOTAVAIL. The send went to the host, which accepted it. sendto, and
sendmsg through it, now fails the same way for an AF_INET datagram socket
that is not connected. connect to port 0 already did.

soreceive_generic keeps a MSG_WAITALL receive on a stream socket waiting until
the buffer is full, the peer closes or an error occurs. The three calls failed
every flag but MSG_PEEK and MSG_DONTWAIT with EOPNOTSUPP. A stream socket now
passes the flag to the host receive; a datagram socket ignores it, as a record
is delivered whole.

In a payload process on a PS5 (firmware 12.70), sysctlbyname returns -1
with ENOENT for thirteen names that threw here, and leaves the buffer and
the length alone, for a read, a size query, a null length and a null
buffer with a null length. sysctl does the same for the fixed MIBs of
seven of them. sysctlnametomib gives those seven MIBs and returns ENOENT
for hw.cacheline_size and hw.usermem, which threw too.
machdep.cacheline_size already returned ENOENT and is now tested with
the others. A write to the new names and MIBs throws, as the console's
answer to a write was not tried. The hw.realmem and vm.overcommit debt
entries now say that a payload process gets ENOENT for them as well.
