fix(libkernel): refuse cpuset sizes the console rejects and record the EPERM difference
...
cpuset_getaffinity and cpuset_setaffinity return ERANGE from 24 bytes, as a PS5 payload process did (rooklz sweep, #7135 comment 6391606624: 8 to 16 accepted, below 8 and from 24 up ERANGE), and throw for the unmeasured 17 to 23, as pthread_getaffinity_np does. The tests that used 32 bytes use 16 and pin 7, 24, 32 and 64 to ERANGE. The setter entry records that the console answers EPERM for a CPU outside the process's set where this clips and returns 0.

fix(libkernel): answer CPU_LEVEL_ROOT and test the cpuset sizes the console accepts
...
cpuset_getaffinity at CPU_LEVEL_ROOT returns 0xffff, as a PS5 payload process read it (rooklz, #7135 comment 6390891591), instead of throwing; the target is checked as at the other levels. The level 2 base-set test now passes 8 and 16 bytes, which the console accepts (it returns ERANGE from 24 bytes), instead of depending on the 32 bytes it rejects. The debt entry records the root measurement and that the title root set is unmeasured.

fix(libkernel): map unbacked AMM PRT pages to one read-only zero page on Windows
...
Unbacked PRT pages were private read-only commits, so every page that was
read took its own host page. They are now views of one pagefile-backed
section created read-only, so the range costs one page however large and
no view of it can be made writable. Host imports treat such views as
read-only memory instead of asking for a read-write alias.

fix(libkernel): keep the libkernel contract on forwarded socket calls
...
bind, getsockname, sendto and recvfrom validate as for a libkernel socket
before they reach libSceNet, so a forwarded descriptor reports the same
errors. recvfrom keeps its guest address handling and MSG_WAITALL, and a
zero-length datagram receive does not wait.

It now names the bounds and the errors, and what the direct calls of the

fix(libkernel): fail a vm.overcommit write with EPERM
...
vm.overcommit is a read-write sysctl without CTLFLAG_PRISON, so FreeBSD 11.4 sysctl_root asks priv_check for PRIV_SYSCTL_WRITE before the handler runs, and prison_priv_check denies it to a jailed root. Under the credential model agreed on #11216 a write through sysctlbyname now fails with EPERM, whatever the value or its length, instead of throwing.

A zero bit pattern and a wait mode that is not exactly AND or OR, or that
sets both clear flags, return EINVAL once the event flag is resolved.
The new entry says so, what three emulators do, and what the titles
checked pass.
