PS5MC (PPSA99420, Kodi 22) imports chflags (ixrw0h2tWuI) from
libkernel.prx, one reference. Predicted stop once the imports ahead of
it (pthread_getthreadid_np, sendfile, wcstok, pause, setrlimit and the
termios calls) are covered (not a run):
FAIL: unresolved ELF import ixrw0h2tWuI from libkernel.prx

sys/kern/vfs_syscalls.c kern_chflagsat and setfflags, and
sys/ufs/ufs/ufs_vnops.c ufs_setattr, for a root caller: the lookup
through the guest resolver gives EFAULT, ENOENT and ENOTDIR (also for a
file reached through a trailing slash or used as a directory), a bit
outside the 17 UFS flags of sys/sys/stat.h (VNOVAL included) gives
EOPNOTSUPP, and SF_SNAPSHOT gives EPERM, since the snapshot flag cannot
be toggled. No host keeps BSD file flags and stat reports st_flags 0,
so flags 0 succeed without touching the file and any other flag throws
with the flags named. UF_READONLY and the other Windows-attribute flags
are not mapped to FILE_ATTRIBUTE_READONLY and its siblings: UFS stores
them without enforcing them, and on Windows the read-only attribute is
already the owner write bit of chmod.

sceCoredumpAttachUserFile (5nc2gdLNsok) and
sceCoredumpAttachMemoryRegionAsUserFile (MEJ7tc7ThwM) get the
signatures of Orbital's db_types.json (cc408367) and SharpProspero's
KernelSystem.cs (5dfdb4b0): (uint32_t userValue, const char* path) and
(uint32_t userValue, const void* mem, size_t size, const char* name).
The handler is never invoked here, so both return
SCE_COREDUMP_ERROR_NOT_IN_COREDUMP_HANDLER (0x81180003, shadPS4
coredump_error.h e0a46675) and attach nothing; a null path or name and
a null, empty or wrapping region throw because the order of the
console's checks is unknown.

PPSA99058 and PPSA99420 import sceKernelGetCpuTemperature and sceKernelGetSocSensorTemperature and stop at start-up on main. Read the host CPU/package, board and NVMe sensors (hwmon/thermal on Linux, the ACPI thermal zones and the storage temperature property on Windows) and report an unsupported sensor with EINVAL.
On Linux, glibc maps the stack of every guest thread near the top of the
host address space (around 0x7fff00000000). On the console, application
stacks lie inside the application area below 0xFC00000000, and guest code
relies on that: ChakraCore's garbage collector indexes a 4 MiB table with
address >> 18, so it only covers addresses below 1 TiB and reports
Js::OutOfMemoryException for a stack above it.
Map each guest thread's stack with DoMapAnon, which allocates from the
guest arena, behind a PROT_NONE guard page, and pass it to pthread_attr_setstack.
The stack is freed after a join; the stack of a detached thread is freed once its
host thread is gone from /proc/self/task.

PS5MC (PPSA99420, Kodi 22) imports clock_settime (d7nUj1LOdDU) from
libkernel.prx, one reference, after sigwaitinfo in its import order.
Predicted stop once the imports ahead of it are covered (not a run):
FAIL: unresolved ELF import d7nUj1LOdDU from libkernel.prx
The NID is computed with tools/nid_names.py and matches aerolib.
Follows FreeBSD 11.4 sys/kern/kern_time.c sys_clock_settime and
kern_clock_settime (8c639945a44588f6cfdddfb057bb5aad88735da0) for a
root caller: EFAULT for a null time (copyin), EINVAL for any clock but
CLOCK_REALTIME and for a negative tv_sec or a tv_nsec outside 0 to
999999999. A valid CLOCK_REALTIME request throws with the requested
time named, since the host clock must not be set and no guest clock
offset is kept.

XPSemu PPSA97358 imports both from libkernel.prx; with the imports ahead
of them covered, its predicted next stops (relink registry order, not an
observed run) are:
FAIL: unresolved ELF import KaK52lYTBIs from libkernel.prx (execv, 7 call sites)
FAIL: unresolved ELF import kdguLiAheLI from libkernel.prx (execve, 4 call sites)
Today the title stops earlier at the observed
FAIL: unresolved ELF import aRo9AhFUXcM from libkernel.prx (sigsetjmp, merged in #3486)
As for execvp (#2827), the process image cannot be replaced here, so both
throw with the execvp message pattern once FreeBSD 11's execve would start
loading the image (freebsd-src 8c639945, sys/kern/kern_exec.c
exec_copyin_args, do_execve, exec_check_permissions; lib/libc/gen/exec.c
execv passes environ). Before that they fail as FreeBSD does: EFAULT for a
null argument vector or path, ENOENT and ENOTDIR from the lookup as stat
reports it, EACCES for a path that is not a regular file. Paths of
PATH_MAX bytes or more and strings over ARG_MAX throw instead of guessing
the console's limits. The execv calls in XPSemu's sources run in a fork
child (net/tap.c), and its fork fails with ENOSYS (ZiZc3/XPSemu 8eec07b4,
ps5/compat/libc_missing.c, ps5/build-title.sh --defsym).
NIDs computed with tools/nid_names.py and confirmed in aerolib.

On a PS5 (firmware 13.60) pthread_setschedparam and
scePthreadSetschedparam accept only SCHED_FIFO and SCHED_RR with a
priority of 256 to 767 or 896 to 959, return EINVAL otherwise, and
keep the policy for pthread_getschedparam. A created thread takes the
policy of explicit scheduling attributes, or its creator's when it
inherits. Here any policy and priority were accepted and SCHED_FIFO
was always reported.

Allow calling threads to query and set affinity using their own thread ID in addition to -1. Return ESRCH for non-matching thread or process IDs and EINVAL for invalid level/which arguments instead of throwing NotImplemented, matching FreeBSD cpuset semantics.
sceKernelVirtualQuery, sceKernelMunmap, sceKernelReleaseDirectMemory and the
reservation paths walked a copy of the whole allocation registry or of every
direct mapping under one lock on each call. The registry now answers lookups
from its ordered map, applies range replacements as patches instead of
rebuilding the map, and direct mappings carry an index by physical offset so a
release finds only the mappings it covers. Minecraft (PPSA17221) holds about
7,000 direct mappings and spent its world generation in these walks.

Three catalog titles stop on Windows when they poll a guest socket for
POLLPRI|POLLOUT to see whether a non-blocking connect has completed:
- PPSA97510 PSXS5 (socket 0x10000002, thread gamedb, 13 s):
what(): poll: POLLPRI is not supported by WSAPoll
- PPSA98510 SwanStation (sockets 0x10000003/0x10000002, threads gamedb
and update): what(): poll: POLLPRI is not supported by WSAPoll
- PPSA99003 ProsperoTV ({0x10000001, POLLPRI|POLLOUT} at 5.3 s):
what(): poll: POLLPRI is not supported by WSAPoll
FreeBSD's sopoll_generic (sys/kern/uipc_socket.c, freebsd-src 8c639945)
reports POLLPRI and POLLRDBAND alike, only while out-of-band data is
pending (so_oobmark or SBS_RCVATMARK). WSAPoll rejects POLLPRI in events
with WSAEINVAL but reports pending urgent data as POLLRDBAND, so on
Windows the guest POLLPRI is now asked of WSAPoll as POLLRDBAND and
POLLIN as POLLRDNORM (Winsock's POLLIN includes POLLRDBAND, which would
report urgent data as readable). Measured on this host: WSAPoll reports
POLLRDBAND after a peer's send(MSG_OOB), waits for it, and clears it once
the byte is read with MSG_OOB. Linux keeps polling POLLPRI on the host.
select needs no change: libkernel's select passes exceptfds as Urgent to
the libSceNet poller, which already asks WSAPoll for POLLRDBAND, and it
does not take libkernel guest sockets on either host.
The guest send and recv refuse MSG_OOB, so urgent data only comes from a
peer outside the guest's sockets; guest_poll now sends it from a host
socket and checks that a connected pair and a non-blocking connect
report POLLOUT and not POLLPRI. TechnicalDebt records where Winsock's
answer differs from FreeBSD's once the stream passes the mark.
Depends on #3649 (poll on file descriptors), whose two commits this
branch carries, since the titles reach this stop only with it.

mlockall (x7g7Ebeo8-U, aerolib) follows FreeBSD 11.4's sys_mlockall
(sys/vm/vm_mmap.c:1067-1131, freebsd-src
8c639945a44588f6cfdddfb057bb5aad88735da0) for the flag check: 0 or
bits outside MCL_CURRENT (1) and MCL_FUTURE (2) fail with EINVAL. The
title process is taken to pass priv_check(PRIV_VM_MLOCK), as mlock
already does.
Valid flags throw. MCL_FUTURE would need every later guest and host
mapping to be locked; nothing in the mapping paths does that, and
passing it to the host would make later host allocations fail above
the host RLIMIT_MEMLOCK. MCL_CURRENT would have to lock the whole
process, which on AnyPS5 also holds host stacks, heaps, modules and
driver mappings (sceKernelVirtualQuery reports them as guest memory),
with ENOMEM above a guest RLIMIT_MEMLOCK that is not known (getrlimit
throws for it). mlock pins host pages (VirtualLock, mlock) range by
range and keeps no record, so there is no state to extend. Recorded
in TechnicalDebt.
XPSemu (PPSA97358) calls it only with -overcommit mem-lock=on
(ZiZc3/XPSemu 8eec07b4, os-posix.c:330-355, reached from
system/vl.c:831-835):
int flags = MCL_CURRENT | MCL_FUTURE;
...
ret = mlockall(flags);
if (ret < 0) {
error_report("mlockall: %s", strerror(errno));
}
and exits on failure, so that option ends in the throw; without it
the title is not affected. Predicted stop removed (registry index 201,
not run):
FAIL: unresolved ELF import x7g7Ebeo8-U from libkernel.prx
guest_mlock checks EINVAL for 0, 4, 5 and -1 and the throw for 1, 2
and 3.

(cherry picked from commit 87f4aa331b02d098fe27516809495447ff6a9fa6)
pthread_atfork (U9t5kJAWPnA, aerolib) appends the prepare, parent and
child handlers to a process-wide list under a lock and returns 0, or
ENOMEM when the entry cannot be allocated, as FreeBSD 11.4's
_pthread_atfork does (lib/libthr/thread/thr_fork.c:78-100, freebsd-src
8c639945a44588f6cfdddfb057bb5aad88735da0). Null handlers are accepted;
FreeBSD's fork skips them. The handlers never run: fork
(libkernel_sys) throws and vfork is absent, so no child process is
created. The list is kept, in registration order, for a later fork
(PthreadAtforkHandlers_nid_no_patch); recorded in TechnicalDebt.
XPSemu (PPSA97358) calls it from a constructor, before main
(ZiZc3/XPSemu 8eec07b4, util/rcu.c:488-495):
static void __attribute__((__constructor__)) rcu_init(void)
{
smp_mb_global_init();
#ifdef CONFIG_POSIX
pthread_atfork(rcu_init_lock, rcu_init_unlock, rcu_init_child);
#endif
rcu_init_complete();
}
so a throwing export would stop the title before main. Predicted stop
removed (registry index 255, not run):
FAIL: unresolved ELF import U9t5kJAWPnA from libkernel.prx
guest_pthread_atfork checks registration order, null handlers,

Black Myth: Wukong (PPSA23226) exits at start-up with
STATUS_DLL_NOT_FOUND after "Failed to load module:
libs\libSceDbgThreadSanitizer.prx". The executable does not need the
library: its bundled sce_module/libSceJobManager_nosubmission.prx lists
it in DT_NEEDED and imports __tsan_acquire and __tsan_release from it,
plus sceKernelIsThreadSanitizerEnabled from libkernel. The relinker
converts every module in sce_module and loads it at start-up (only
--module-dir directories are deferred), and GuestModuleBuilder adds each
module's host dependencies to the executable's DT_NEEDED, which the
Windows start-up stub loads.
libSceDbgThreadSanitizer now exports __tsan_acquire and __tsan_release
with the void(void* addr) signatures of LLVM compiler-rt's
tsan_interface.h (llvm-project 87f0227cb601, LLVM 20.1.8). Both throw:
AnyPS5 runs no race detector, and the module calls them only after
sceKernelIsThreadSanitizerEnabled reports the sanitizer enabled.
libkernel's sceKernelIsThreadSanitizerEnabled returns 0, as
sceKernelIsAddressSanitizerEnabled does; its int(void) signature is
assumed and recorded in the libkernel debt file.

sceCoredumpWriteUserData (Dbbkj6YHWdo) and sceCoredumpDebugTextOut
(dei8oUx6DbU) get the signatures of Orbital's db_types.json (cc408367)
and SharpProspero's KernelSystem.cs (5dfdb4b0): ssize_t (const void*,
size_t) and void (const char*, int). WriteUserData moves out of
Unimplemented.cpp.
User data belongs to the core dump handler: the Vita's
sceCoredumpWriteUserData returns 0x800A0003 ("No user-data capture is
active") outside it (vita-headers e66ebe90), and the RED engine's PS4
crash handler makes every coredump call from its handler (Vangaurd
4f86d2b0). The handler is never invoked here, so WriteUserData returns
SCE_COREDUMP_ERROR_NOT_IN_COREDUMP_HANDLER (0x81180003, shadPS4
coredump_error.h e0a46675) sign-extended and keeps nothing; a null,
empty or wrapping buffer throws because the order of the console's
checks is unknown. DebugTextOut prints its text to stderr with the
[coredump] prefix; a negative length or a null text with a nonzero
length throws.
Evidence: Broken Sword Reforged (PPSA21480) reaches the family through
its sibling, #3704 comment 6113687542: "`ERROR agc_graphics.cpp:266
Sony call failed with code 8a6c9018` (the resource registration error,
followed by the error dialog), then `sceCoredumpWriteUserString not
implemented`." WriteUserString has no declaration in any source and
keeps throwing; its TechnicalDebt entry records the call. 007 First
Light (PPSA11386) imports WriteUserData (#2523) without calling it
before its stop.
Test: guest_coredump_user_data.

FreeBSD's in_getsockaddr and in6_getsockaddr succeed for a socket that has no
local address and return the wildcard address with port 0. Winsock fails
getsockname with WSAEINVAL until the socket is bound, which the guest saw as
EINVAL. Return the zero address of the socket's family for that error.
