This is already fixed in v2.0 and master

v1.7.9

SONAME to 7.1 because of lws_snprintf()

lws_snprintf

Thanks to Fabrice Gilot for reporting the problem that led to uncovering this.

Due to a misunderstanding of the return value of snprintf (it is not truncated according
to the max size passed in) in places relying on snprintf to truncate the length
overflows are possible.

This patch wraps snprintf with a new lws_snprintf() which does truncate its length to allow
the buffer limiting scheme to work properly.

All users should update with these fixes.

In 1.7.x, there's no affected code in the library itself, just a couple on instances in the
test app code.

recv revert treating zero as hangup

While checking with ab, I found
commit 30cdb3ac8f24a4c289a3b4e8a41d6c5f2e6ec959
Author: Justin Chen <justinchen00@github.invalid.com>
Date:   Thu Apr 14 21:40:53 2016 +0800

    recv treat zero return as error

    https://github.com/warmcat/libwebsockets/issues/475

turned ab performance to crap, reverting it made everything fast again.

recv manpage says there is three ways to get zero returned

1)       When a stream socket peer has performed an orderly shutdown, the return value will be 0  (the  traditional  "end-of-file"
       return).

2)       Datagram  sockets  in  various  domains  (e.g., the UNIX and Internet domains) permit zero-length datagrams.  When such a
       datagram is received, the return value is 0.

3)       The value 0 may also be returned if the requested number of bytes to receive from a stream socket was 0.

we can't just assume it means the peer shut down.

If the peer shut down, then the event loop should get an event on the socket like POLLHUP and deal with it that way.

So the patch mentioned above is simply reverted here.

Add a test html button that will send 9KB of junk to confirm it

https://github.com/warmcat/libwebsockets/issues/480

permessage-deflate now checks the protocol rx buffer size for being
>=128, if not, permessage-deflate is disabled on that connection.

If it is >=128 but less than the zlib decompress buffer size, the
zlib decompress buffer size for that connection is reduced to the
nearest power of two of the protocol rx buf size.

To test this, dumb_increment is left violating the >= 128 rx buffer
size and permessage-deflte can be seen to be disabled on his

ah move more_rx_waiting to wsi scope

Originally this was alright in wsi->u.hdr, because ah implied header
processing.  But since we allowed ah to be held across http
keep-alive transactions if we saw we had more header data, it means
we were trying to read this union member out of scope after it had
transitioned.

Moving the more_rx_waiting member to be a 1-bit bifield in the wsi
solves it and lets us check the state any time later at http
transaction completion.
