PS5MC (PPSA99420, Kodi 22) imports getpriority (miQ1wVwSexE) from
libkernel.prx, one reference, next to chflags in its import order.
Predicted stop once the imports ahead of it are covered (not a run):
FAIL: unresolved ELF import miQ1wVwSexE from libkernel.prx
The NID is computed with tools/nid_names.py and matches aerolib.
Follows FreeBSD 11.4 sys/kern/kern_resource.c sys_getpriority
(8c639945a44588f6cfdddfb057bb5aad88735da0) for the only guest process,
taken to run at nice 0 and to lead its own process group (as kill and
setsid already assume): PRIO_PROCESS and PRIO_PGRP with 0 or its pid,
and PRIO_USER with 0 or its uid 0, return 0; other ids give ESRCH and
an unknown which gives EINVAL. getpriority is a bare system call in
FreeBSD's libc (lib/libc/sys/Symbol.map), so errno is left unchanged
on success.

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.

(cherry picked from commit 16e5b7ccd04e6467a5a282b6cfc9271304f42244)
Windows 10 1903 deletes a file with open handles by moving it into
$Extend\$Deleted until the last handle closes, so the next snapshot of a
watched file that a title (or the test) deleted saw a new path, tried to
watch that directory's changes, got ERROR_ACCESS_DENIED and threw from
the watch thread, which aborts the process; the path change was also
reported as NOTE_RENAME next to NOTE_DELETE. A snapshot with a pending
delete or no links now reports NOTE_DELETE alone and drops the parent
directory watch instead of replacing it, as the file has no directory
to be renamed or removed from any more.
PS5CEMU-HAR (PPSA99360, ps5-payload-dev build, relinks with
--trap-sdk-syscall-stubs) imports pthread_setaffinity_np (5KWrg7-ZqvE)
from libkernel.prx. babyhuey's run with #3787 merged onto main e7c70a2d

Windows: FAIL: unresolved ELF import 5KWrg7-ZqvE (pthread_setaffinity_np) from libkernel.prx
Linux: undefined symbol: 5KWrg7-ZqvE (pthread_setaffinity_np)
It follows FreeBSD 11.4 libthr thr_affinity.c (8c639945) over
kern_cpuset_setaffinity: another thread is looked up first (EINVAL for
null, ESRCH when unknown or finished, as _thr_find_thread without dead
threads), a size other than the 32-byte cpuset_t returns ERANGE, the
mask is clipped to sceKernelGetAvailableCpumask and an empty result
returns EDEADLK, as cpuset_setaffinity does. The affinity is stored on
the guest thread through scePthreadSetaffinity, for the caller and for
any live guest thread.

sceCoredumpAttachUserFile (5nc2gdLNsok) and
sceCoredumpAttachMemoryRegionAsUserFile (MEJ7tc7ThwM) get the

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.

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).

(cherry picked from commit 57f0fa37132bc6c78bc02282044a00e2db859484)
getsockopt and setsockopt on a libkernel socket knew four SOL_SOCKET options
(SO_REUSEADDR, SO_BROADCAST, SO_SNDBUF, SO_RCVBUF) and failed every other
one with ENOPROTOOPT. The Mound's EOS SDK reads SO_ERROR on two of its
sockets after a connect, which therefore always failed.
The SOL_SOCKET options now follow FreeBSD 11.4 sosetopt and sogetopt:
- SO_ERROR returns the pending error of the socket as a FreeBSD errno and
reports it once (Winsock does not clear it on read, so the library does).
- SO_TYPE, SO_ACCEPTCONN, SO_KEEPALIVE, SO_DONTROUTE, SO_OOBINLINE and
SO_LINGER are read from and set on the host socket; the boolean options
read back as their own bit, as FreeBSD returns so_options & option.
- SO_DEBUG, SO_USELOOPBACK, SO_REUSEPORT, SO_TIMESTAMP and SO_NOSIGPIPE stay
ENOPROTOOPT until a title needs one.
- A value is read from its first int and fails with EINVAL when shorter, a
getsockopt buffer is filled up to its length (sooptcopyin, sooptcopyout),
SO_SNDBUF and SO_RCVBUF below 1 fail with EINVAL, and SO_LINGER outside
0..65535 seconds fails with EDOM.
A connect on a non-blocking socket now fails with EINPROGRESS on Windows too
(it was EWOULDBLOCK, which a title waiting for the connection does not
expect).

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.
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

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,
concurrent registration from four threads and that no handler runs.
