When the UPnP server is started, one alive message is broadcast for each
service in each device. It appears that libupnp's implementation of the
alive message generation does not correctly navigate the XML description
document when locating the services. This can result in the wrong UDN
being used in the alive message sent for a service.
In my specific case (see attached XML), the root EchoSTB device contains
no services, but its embedded MediaServer device contains 2 services.
When the existing libupnp code traverses the EchoSTB device in the XML,
it searches the global list of serviceLists within the document instead
of searching for a serviceList that is its direct child node. The
ContentDirectory and ConnectionManager services are then announced with
the UDN of EchoSTB1 (the root device) instead of with the UDN of
MediaServer, which is actually their parent device.
I discovered this behavior using libupnp-1.6.6. I have generated a patch
against branch-1.6.x that corrects the XML navigation such that all
services are traversed from their parent device, which results in the
correct UDN being sent in the alive message for each service. I built
from branch-1.6.x without this patch, tested, and confirmed that the
issue still exists as I observed it in libupnp-1.6.6. I then built
from branch-1.6.x with this patch, tested, and confirmed that the
issue was resolved.
Thanks,
Chuck Thomason

Thanks for the load of updates, I'm still assimilating them ! Could I make
a suggestion though? The addition of printNodes(IXML_Node) to upnpdebug a
dds a new dependency on ixml.h for anything using upnpdebug.h. I'm making
quite a bit of use of upnpdebug in porting things to version 1.8.0, and I'd
prefer it if printNodes could be added to ixmldebug.h instead. I'm attach
ing a patch, what do you think ?

* SF Bug Tracker [ 2876374 ] Access Violation when compiling with Visual Studio 2008
Submitted: Stulle ( stulleamgym ) - 2009-10-10 19:05
Hi,
I am one of the devs of the MorphXT project and I use this lib in some
other of my projects, too. When I tried to upgrade the lib earlier for one
of my projects I had to realise that something did not work at first and
while most of the things were reasonably ease to be fixed. Now, the last
thing I encountered was not so easy to fix and I am uncertain if my fix is
any good so I'll just post it here and wait for some comments.
The problem was that I got an Access Violation when calling "UpnpInit". It
would call "ithread_rwlock_init(&GlobalHndRWLock, NULL)" which eventually
led to calling "pthread_cond_init" and I got the error notice at
"EnterCriticalSection (&ptw32_cond_list_lock);". It appeared that
"ptw32_cond_list_lock" was NULL. Now, I found two ways to fix this. Firstly
moving the whole block after at least one of the "ThreadPoolInit" calls
will fix the issue. Secondly, you could add:
#ifdef WIN32
#ifdef PTW32_STATIC_LIB
// to get the following working we need this... is it a good patch or
not... I do not know!
pthread_win32_process_attach_np();
#endif
#endif
right before "ithread_rwlock_init(&GlobalHndRWLock, NULL)".
Just so you know, I am using libupnp 1.6.6 and libpthreads 2.8.0 and both
are linked static into the binaries. I am currently using Visual Studio
2008 for development with Windows being the target OS. Any comment at your
end?
Regards, Stulle

* SF Bug Tracker [ 2392304 ] Memory leak in SSDP AdvertiseAndReply
Submitted: Ulrik ( ulsv_enea ) - 2008-12-05 08:24
Valgrind reports a memory leak function in AdvertiseAndReply
(ssdp/ssdp_server.c) in libupnp 1.6.6
There are continue statements in many places in AdvertiseAndReply. In some
of those error handling cases the variable nodelist is not free'ed before
continuing to the next iteration. The next iteration will take care of
free'ing the nodelist from the previous iteration in most cases, but not
when breaking out of the for loop after the last element.
I belive this memory leak can be solved by makeing sure that the rows
ixmlNodeList_free( nodeList );
nodeList = NULL;
are always executed, also in the beginning of the last iteration when we
found out that there are not more elements.

Submited by Carlo Parata from STMicroelectronics.
Hi Roberto and Nektarios,
after an analysis of the problem of libupnp with a multi-flows scenario, I
noticed that the only cause of the freezed system is the ThreadPool
management. There are not mutex problems. In practise, if all threads in the
thread pool are busy executing jobs, a new worker thread should be created if
a job is scheduled (I inspired to tombupnp library). So I solved the problem
with a little patch in threadutil library that you can find attached in this
e-mail. I hope to have helped you.

SF Patch Tracker [ 2836704 ] Search for nested serviceList (not
stopping at the first lis
Submitted By: zephyrus ( zephyrus00jp )
Internet Gateway Device description contains nested serviceList (rootdevice
-> servicelist, subdevice
and subdevice has the lower-level serviceList, etc..)
Unfrotunately, the sample code sample_util.c used by tv_device sample,
etc.
has a code that looks for only the first top-level serviceList.
This results in the failure to read all the services of an IGD xml
description.
Attached patch modifies this behavior and looks for the service by
visiting all the serviceList in xml document in turn.
With the modified patch (ad additional modification), I could
simulate an IGD device and created a modified control program for that.
Patch against 1.6.6
TIA.

(void) argument list.
Submitted By: zephyrus ( zephyrus00jp )
In a publicly installed headers, a few functions are declared without any
arguments at all, a la "()".
When I used gcc's -Wimplict and -Wstrict-prototypes to check for the
mismatch of
function prototype declarations and their usage in my own program,
some headers from libupnp-1.6.6 produced warnings.
They are not strictly bugs, but pretty much annoying. This is 2009, and
almost all the important compilers
understand ISO-C.
So the offending functions are declared as "(void") to show that they have
no arguments at all.

Seems like SF's tracker won't let me add a patch to someone else's issue ?!
This refers to https://sourceforge.net/support/tracker.php?aid=2724578
The calls to inet_ntoa are in getlocalhostname(), which is called from
UpnpInit when it is returning the bound IP address.
UpnpInit/getlocalhostname hasn't been updated to IPv6, I presume this is
deliberate so that it doesn't start returning IPv6 addresses and
overwriting the caller's IPv4-sized allocation.
The attached patch just updates getlocalhostname to use inet_ntop instead
of inet_ntoa, and also documents the fact that UpnpInit is IPv4 only whilst
UpnpInnit2 is both IPv4 and IPv6.
A fuller solution might be to change UpnpInit to use some variant on
UpnpGetIfInfo. UpnpInit could still be left as IPv4 only if desired -
perhaps UpnpGetIfInfo could take an option for the desired address family.
getlocalhostname and its own copy of the interface scanning code would then
be redundant. I don't have IPv6 capability here though so I'm reluctant to
change the IPv6 code, as I have no way to test it.

add devices.
each time a device been added, UpnpInit() is called, on exit, UpnpFinish()
is called, but the memories allocated by ThreadPoolInit() may lost because
there's no code to call ThreadPoolShutdown() to release the memories. And
inet_ntoa() is not thread safe, so in my patch, I substitute inet_ntoa()
with inet_ntop().

SOAPACTION and User-Agent headers.
There is something going wrong in soap_ctrlpt.c at line 931 (based on
version 1.6.6 release).
The http_Makemessage call looks as follows:
if (http_MakeMessage(
&request, 1, 1,
"Q" "sbc" "N" "s" "s" "Ucc" "sss",
SOAPMETHOD_POST, path.buf, path.length,
"HOST: ", host.buf, host.length,
content_length,
ContentTypeHeader,
"SOAPACTION:
\"urn:schemas-upnp-org:control-1-0#QueryStateVariable\"",
xml_start, var_name, xml_end ) != 0 ) {
return UPNP_E_OUTOF_MEMORY;
}
This will result in the SOAPACTION header to be immediately followed by the
User-Agent header, while a cr-lf should separate the two. I propose to fix
this by changing the second "s" to "sc" to force the addition of a cr-lf
after the SOAPACTION. This looks consistent to the other Makemessage calls.
