The EINVAL for a descriptor without a vnode now applies only to a pipe or socket. A character device is a vnode on FreeBSD, so getvnode succeeds and change_dir fails with ENOTDIR; File::IsCharacterDevice keeps that answer for the host character devices (a tty, NUL or /dev/null) and the guest random device. guest_kernel_sys pins it with /dev/random.

FreeBSD 11.4's sys_fchdir resolves the descriptor with getvnode, which fails with EINVAL for a descriptor that has no vnode; only a vnode that is not a directory gives ENOTDIR from change_dir. fchdir returned ENOTDIR for a pipe or socket. A descriptor that is neither a vnode nor a random device now gets EINVAL; the debt entry records the order of the three errors.

PPSA12361 binds color format 7 (COLOR_11_11_10, float) with COMP_SWAP 0
and stops on "unsupported color format 7 number type 7 component swap 0".
Only the reversed order (COMP_SWAP 2) was accepted.
The format keeps its 10-bit component in the low bits. The standard
swap puts red in the first slot, as Mesa pairs SWAP_STD with
COLOR_10_11_11 for R11G11B10_FLOAT, so COMP_SWAP 0 puts red there and
COMP_SWAP 2 blue. Swap 0 now decodes with the identity export mapping
0xe4 and the same packing; the other swaps still throw.
The decode test accepts swap 0 and keeps refusing swaps 1 and 3. The
execution test renders both orders into tiled and linear targets and
compares each stored word with the packing of the order. Its program
pool grows to fit the second pass. The debt entry names the accepted
orders and says the swap 0 layout is derived, not measured.

sosend_generic fails a send on a socket that can send no more with EPIPE
before it looks at so_error. Winsock reports the same send as WSAECONNABORTED
or WSAECONNRESET, which reached the guest as ECONNABORTED or ECONNRESET.
A stream send now maps both to EPIPE. The send-after-close checks of
guest_tcp, guest_socket_read_write and guest_socket_pair run on Windows too.

A FLAT_SHADE input without pass-through that a pixel shader reads
through v_interp_mov_f32 P20 and not P10 stayed an explicit per-vertex
input and read vertex 2 minus vertex 0. For a flat value that is the same
on every vertex the difference is 0, and with the first provoking vertex
nothing refused it.
ps5-opengl lowers every flat input to a load of one vertex: vertex 1
(P10) by default, which #4030 reads as the provoking vertex, and vertex 2
(P20) for triangles when GL's flatshade_first is set. SuperTuxKart's
deferred point lights are drawn that way, so all twelve flat inputs of
pointlight.frag read 0, the attenuation 0 * -inf was NaN, nothing was
discarded, and the starting-line referee's light quad blacked out the
scene behind it (#8364).
A P20-only read now returns the provoking vertex's value, as P10 and P0
do. The lane was not measured on the console either, so FragmentParameter
records it and a pipeline using the last provoking vertex throws. An input
read through both P10 and P20 keeps its per-vertex differences.
