Date: Mon, 9 Jan 2017 13:37:51 -0600
Subject: [PATCH] tcp: set socket buffer sizes before listen/connect/accept

Attempting to set SO_RCVBUF and SO_SNDBUF on TCP sockets after connection
establishment is incorrect and some stacks ignore the set call on the socket at
this point.  This has been observed on MacOS/iOS.  Windows 7 has some peculiar
behavior where setting SO_RCVBUF after applies only if the buffer is increasing
from the default while decreases are ignored.  This is possibly how the incorrect
usage has gone unnoticed

Unix Network Programming Vol. 1: The Sockets Networking API (3rd edition, seciton 7.5):

"When setting the size of the TCP socket receive buffer, the ordering of the
function calls is important.  This is because of TCP's window scale option,
which is exchanged with the peer on SYN segments when the connection is
established. For a client, this means the SO_RCVBUF socket option must be
set before calling connect.  For a server, this means the socket option must
be set for the listening socket before calling listen.  Setting this option
for the connected socket will have no effect whatsoever on the possible window
scale option because accept does not return with the connected socket until
TCP's three-way handshake is complete.  This is why the option must be set on
the listening socket. (The sizes of the socket buffers are always inherited from
the listening socket by the newly created connected socket)"

in 16 bits, so there's no lengthening/narrowing in the filter at all.

For the full 16 pixel wide filter, we can only process 4 pixels at a time
(using an implementation very much similar to the one for 8 bpp),
but we can do 8 pixels at a time for the 4 and 8 pixel wide filters with
a different implementation of the core filter.

The speedup vs C code measured in checkasm is around 1.1-4x.
These numbers are quite inconclusive though, since the checkasm test
runs multiple filterings on top of each other, so later rounds might
end up with different codepaths (different decisions on which filter
to apply, based on input pixel differences).

Based on START_TIMER/STOP_TIMER wrapping around a few individual
functions, the speedup vs C code is around 2-4x.

arm: Add NEON optimizations for 10 and 12 bit vp9 itxfm

This work is sponsored by, and copyright, Google.

This is structured similarly to the 8 bit version. In the 8 bit
version, the coefficients are 16 bits, and intermediates are 32 bits.

Here, the coefficients are 32 bit. For the 4x4 transforms for 10 bit
content, the intermediates also fit in 32 bits, but for all other
transforms (4x4 for 12 bit content, and 8x8 and larger for both 10
and 12 bit) the intermediates are 64 bit.

For the existing 8 bit case, the 8x8 transform fit all coefficients in
registers; for 10/12 bit, when the coefficients are 32 bit, the 8x8
transform also has to be done in slices of 4 pixels (just as 16x16 and
32x32 for 8 bit).

The slice width also shrinks from 4 elements to 2 elements in parallel
for the 16x16 and 32x32 cases.

The 16 bit coefficients from idct_coeffs and similar tables also need
to be lenghtened to 32 bit in order to be used in multiplication with
vectors with 32 bit elements. This leads to the fixed coefficient
vectors needing more space, leading to more cases where they have to
be reloaded within the transform (in iadst16).

This technically would need testing in checkasm for subpartitions
in increments of 2, but that slows down normal checkasm runs
excessively.

arm: Add NEON optimizations for 10 and 12 bit vp9 MC

This work is sponsored by, and copyright, Google.

The plain pixel put/copy functions are used from the 8 bit version,
for the double size (e.g. put16 uses ff_vp9_copy32_neon), and a new
copy128 is added.

Compared with the 8 bit version, the filters can no longer use the
trick to accumulate in 16 bit with only saturation at the end, but now
the accumulators need to be 32 bit. This avoids the need to keep track
of which filter index is the largest though, reducing the size of the
executable code for these filters.

For the horizontal filters, we only do 4 or 8 pixels wide in parallel
(while doing two rows at a time), since we don't have enough register
space to filter 16 pixels wide.

For the vertical filters, we still do 4 and 8 pixels in parallel just
as in the 8 bit case, but we need to store the output after every 2
rows instead of after every 4 rows.

avcodec/cuvid: fail early if GPU can't handle video resolution

CUVID on GeForce GT 730 and GeForce GTX 1060 does not report any error when
decoding 8K h264 packets. However, it does return an error during
cuvidCreateDecoder call if the indicated video resolution is not
supported.

Given that stream resolution is typically known as a result of probing
it is better to use this information during avcodec_open2 call to fail
immediately, rather than proceeding to decode and never receiving any
frames from the decoder nor receiving any indication of decode failure.

so we crash with a null pb when av_write_trailer flushes the packet
