BunnyFl measured both calls in firmware 13.42 libSceNet.sprx, run in an
emulator on the module itself. sceNetInitParam returns 0x80410116 for a
null parameter. The first non-null call copies the first 32 bytes of the
parameter and returns 0, and every later call returns 0x80410110, with a
null parameter and after sceNetTerm too, because the flag is never
cleared. sceNetConfigGetIfFlags returns 0x8041130E for a null flags
pointer before anything else. Both replace throws that stood in for the
unknown answers.
The first successful sceNetInitParam still marks the library initialized,
as sceNetInit does here, because the other calls check it. The module
reads only bit 0 of the stored copy's first word, to raise the pool limit
of sceNetPoolCreate from 32 to 128; that limit is recorded as not
modelled, as sceNetPoolCreate here has none.
sceNetConfigGetIfFlags answers interface 0, lo0 in the sceNetGetIfName
numbering, with IFF_UP | IFF_LOOPBACK | IFF_RUNNING | IFF_MULTICAST, the
flags FreeBSD 11 gives a configured loopback. Other interfaces and a null
flags pointer throw: the library models no other interface.
sceNetInitParam initializes the library as sceNetInit does and returns
its result. NetInitializeParameter's layout is unknown, so its fields are
not read; a null parameter throws because its console result is unknown.
Resolve a FreeBSD/ELF tls_index {module, offset} the way the relinker's
DTPMOD64 values are laid out: on Windows through the PE _tls_index the
module word points at and the thread's ThreadLocalStoragePointer, on
Linux through glibc's __tls_get_addr.
A string created from a text source in the default horizontal form (0x10)
reported 0x10. TEKKEN: DARK RESURRECTION (PPSA31371) passes the reported form
to sceFontCreateWritingLine, which only accepts 0x11 and 0x12, so the call
failed and the layout width was 0.
On firmware 13.42 sceFontCreateString decides the direction for a default-form
source and sceFontStringGetWritingForm returns the stored form. The string
gets 0x12 when its first strong character is left to right, 0x11 when it is
right to left, and 0x12 when it has none. Left-to-right and right-to-left marks
count as strong, embeddings and overrides do not, and text between an isolate
initiator and its PDI is skipped. Explicit 0x11 and 0x12 sources keep their
form.
The test follows the table reported on the pull request. Which characters are
strong is decided by Unicode block ranges here, not by the full bidi class
tables.
scePthreadMutexTimedlock on a mutex the caller holds, and
scePthreadRwlockTimedrdlock and scePthreadRwlockTimedwrlock on a rwlock
it holds for writing, returned EDEADLK at once. The console returns
ETIMEDOUT, as the prosper console oracle measured. They now sleep until
the timeout and return ETIMEDOUT, as FreeBSD libthr does. The POSIX
timed locks call these and change with them.

sceUsbdGetDevice, sceUsbdGetDeviceSpeed, sceUsbdGetMaxPacketSize,
sceUsbdGetMaxIsoPacketSize, sceUsbdOpenDeviceWithVidPid,
sceUsbdSetInterfaceAltSetting, sceUsbdClearHalt and
sceUsbdDetachKernelDriver follow FreeBSD 11.4 libusb10.c over the host
libusb. The packet sizes and the alternate setting checks are done as
FreeBSD does them, so the library records which interfaces are claimed,
and a device stays known while a handle to it is open.
