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 c73d870f46a9be94bc0e7b898dba4e480348933e)
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 ab54cb3dc5ac6b30f6566593804a919473d4e6a5)
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.

Add Content-Language header in the response if and only if there is an Accept-Language header in the request.
Manually ported from revision d2238615e347c45c6abd255597d304cf50b763b5.
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/).

Hi,
I've made some modification to the libupnp v1.6.5
I've add a timeout for each TCP connect.
It is very useful when an UPnP device stop working and do not accept
connection for an UPnP action.
Modifications are only located in
upnp/src/genlib/net/http/httpreadwrite.c
For every TCP connection, I set the socket to non-blocking, perform
connect,
check result and wait during a timeout if necessary, then reset the
socket to blocking.
Please see this patch in attached file.
I hope it helps.

I discovered a reliable denial-of-service issue on the last stable

unauthenticated user. The issue is related with a bad parsing of
malformed XML.
