I had to do some modifications myself though, because the Android
build system insists on having a file named "util.h" taking precedence
in its include path, libupnp gets confused because of the same filename
in upnp/src/inc/util.h

Fix a bug in miniserver.c, in which maxMiniSock was wrongly declared as
unsigned int and as a result it was beeng set to ((unsigned int)(-1)).
As a result, after beeing incremented, it became zero, and this value
was beeing used in the select() call.
Thanks to Fabrice Fontaine for helping and testing with this issue.

the sleep() call, it was just a workaround.
SF Bug Tracker [ 3086852 ] 99% CPU loop in miniserver.c on a non ipv6
system.
Submitted by: Jin ( jin_eld ) - 2010-10-13 19:29:13 UTC
I cross compiled libupnp 1.6.7 for ARM9 using the --disable-ipv6
option, my system is an ipv4 only setup.
I do not know why this problem only appears when running the app in the
background (for instance using nohup &), but then it starts using 99%
CPU.
I traced the problem down to the select() call in miniserver.c in the
RunMiniServer() function. Select returns code 1, but errno is set to
"Socket operation on non-socket", I also see this when running my app
under strace.
I set all ...Sock6 variables to INVALID_SOCKET to make sure that they
do not get added to the FD_SET and the problem is gone.

Adding a configure flag to disable GENA notification reordering as even
with an imillisleep(1), this mechanism consumes too much CPU on embedded
devices when there is a burst of notifications.
(cherry picked from commit c73d870f46)
When a device with embedded devices (like IGD) when created and one of
the embedded devices did not have any service, there was a Segmentation
Fault (see SF Tracker [ 2688125 ]).
(cherry picked from commit ab54cb3dc5)
When a lot of notifications were generated by a device in a short
period of time then 100% of the CPU was used to reorder those
notifications by pushing back the thread in the job queue. This
mechanism has been modified so now thread sleep 1 ms before being
pushed back into the job queue.
Removing DEFAULT_SCHED_PARAM parameter and use
sched_get_priority_min(DEFAULT_POLICY) instead.

Devices must respond to M-SEARCH requests for any supported version and the
response should specify the same version as was contained in the search target.
Previously, the device did not answer if the M-SEARCH request did not
contain the same version number than the version number of the device.
(cherry picked from commit 4966423d96)
Add Content-Language header in the response if and only if there is an Accept-Language header in the request.
Manually ported from revision d2238615e3.
This patch adds the WEB_SERVER_CONTENT_LANGUAGE parameter so the user can specify
the language used by the device during Description and Presentation steps of UPnP
through the HTTP CONTENT-LANGUAGE header.
By default, the WEB_SERVER_CONTENT_LANGUAGE is an empty string so no
CONTENT-LANGUAGE is added.

This patch allows a user to customize the stack size of the threads used by
pupnp through the new THREAD_STACK_SIZE variable. This is especially useful
on embedded systems with limited memory where the user can set THREAD_STACK_SIZE
to ITHREAD_STACK_MIN.
However, as this modification can have side effects, I set 0 as the default
value, so threads will continue to use the default stack size of the system
(which varies greatly as stated in
https://computing.llnl.gov/tutorials/pthreads/).
