Re: [SR-Users] Error loading carrierroute in Kamailio 4.0.x
I'm running some problems atm witch don't allow me to test. Well, if carrierroute built than you already have libconfuse-dev. Carrierroute uses libconfuse as a shared library. I would suggest doing a ldd carrieroute.so and than check that you have the confuse library needed as a carrierroute dependency in /usr/lib/. I found sometimes that there might be some symlinks missing in the system libraries dir, especially for something as 'deprecated' as libconfuse is.

I just checked by running ldconfig -v, and the libconfuse library is indeed in there. I even rebuilt to make sure the ldconfig I just ran didnt affect anything. Same carrierroute.so size, same end result.

Be sure that you install both libconfuse-dev (for header) and libconfuse (can't even remember if it's packed in Debian anymore). Make double sure the library is present in your $LD_LIBRARY_PATH . Anyway, some time ago there were plans to rewrite the configuration parsing of carrierroute so that it remove the dependencies of libconfuse? Any updates on that? M.

Hello Daniel, You were right in the end.

HTTPS is no longer something hard to get in any application. So far so good with the new system, no spammer got that familiar with Kamailio modules :-), but there were few new valid accounts. Well, I would be very nice for the https://www.kamailio.org to work (at the moment it returns an 200 OK with an empty HTML Page). Also, I consider bad security practice to allow traffic that is uncrypted for login forms, but I agree it has small benefits. You can access the login forms via https and it is recommended to use https for logging it, as mentioned on the front page of dokuwiki -- I just said that the https vs http does not bring benefits against spammers. 2. Fix the kamailio.org certificate. At the moment the identity of the domain can't be established as there is no issuer chain provided with it. From Firefox information page: You actually need to fix Firefox -- I struggled yesterday a bit with same situation. The certificate is actually new, generated yesterday and signed by CACert.org. The previous one was selfsigned, from openser times, expired for few years. I had to try other browsers to check if works, because Firefox was displaying some error. Then I went back to stable channel from beta channel without any success, even removing the old certificate from firefox preference. To solve it, I cleared the cache. I have tried with both Chrome and Firefox, both normal and Incognito mode. Same error. I believe the problem is with the server. It is working fine for me over https, tried both firefox and chrome. I replaced the certificate because the previous one was expired and mentioning openser. CACert is not a default trusted authority anyhow, I choose that instead of another self signed certificate because CACert has some popularity out there in the open source space. So, you don't really get to the content via https? Or is just that the browser does not trust it? Cheers, Daniel The server provides the correct certificate (I've downloaded it), but it must provide also an intermediate certificate signed with CaCert RootCA. The client only has the Root CA, so for authentication of the cert the intermediate one is needed. I guess https://www.globalsign.com/support/install/install_apache.phpprovides a solution ( Note that the root CA might not make sense) - Your virtual host section will need to contain the following directives: - *SSLCACertificateFile* – This will need to point to the appropriate GlobalSign root CA certificate. - *SSLCertificateChainFile* – This will need to point to the appropriate intermediate root CA certificates you previously created in Step 1 above. - *SSLCertificateFile* – This will need to point to the end entity certificate (the one you have called mydomain.crt) - *SSLCertificateKeyFile* – This will need to point to the private key file associated with your certificate. Let me know if works for you in the same way. Cheers, Daniel kamailio.org uses an invalid security certificate. The certificate is not trusted because no issuer chain was provided.

Hello, Too little information to go on here. A reload might fail mostly because data from the DB (e.g. with carrierroute case) is first loaded into private memory (the sql result). Depending of the module there are other tricks you could do (decrease the number of fetch rows the query returns etc.). The out of memory condition affects shared or private mem. Try to use at least 15 MB for PKG mem. If the 39% is with traffic, then it's normal, if you don't have any traffic I still would not worry. The thing that worries me a little is the value, you are using from the start around 0.8 GB of used shared memory... this is a lot. From the percentages you provided it looks ok Marius Uri On 09/05/2012 10:19 AM, Uri Shacked wrote: /Hi, //When I start kamailio it loads some data into memory. //Now calls are starting to gather up.

Re: [SR-Users] Shared memory fragmentation

They have 128 MB shared memory and The shared memory is too little. Keep in mind that this is shared by all children, so it will not increase with the creating of more children. Also keep in mind that the Linux memory alocator (like for mmap) is lazy, so allocating 1 GB by the application will not use 1 GB of RAM, but instead pages will be delivered to the application as it needs it. To force allocation there is the shm_force_alloc core parameter to really force allocation of memory by the system bye writing 0's to the memory reagion. Also there is the mlock_pages parameter that will force the allocated memory pages to not be swappable. modparam(carrierroute, config_source, db) modparam(carrierroute, db_url, DBURL) modparam(carrierroute, fetch_rows, 500) Fetch_rows is affects the private memory used when loading data from a data source that has the fetch result capability. This decreases the private memory requirements for reloading the table. The carrierroute table is about 91K lines and have been growing slowly. From experience this takes around 60-70 MB of shared memory to hold it. This depends a lot based on system (32 vs 64 for example), structure etc. Suddenly we get this ERROR: carrierroute [cr_data.c:585]: could not allocate shared memory from available pool after a few kamctl cr reload. I increased the shared memory to 256 MB but with the same result. I have now increased it to 512 MB and it seems to work better now. I have noticed this. After a restart the shmem counters is like this: shmem:total_size = 536870912 shmem:used_size = 28486752 shmem:real_used_size = 40147128 shmem:max_used_size = 41135424 shmem:free_size = 496723784 shmem:fragments = 555 And after the first kamctl cr reload it is like this: shmem:total_size = 536870912 shmem:used_size = 28619016 shmem:real_used_size = 51842768 shmem:max_used_size = 76993616 shmem:free_size = 485028144 shmem:fragments = 722063 I would worry if the used_size or real_used_size would have changed a lot. The difference from used_size to real_used_size is due to fragmentation but this will be manageable if the number of fragments is kept constant. As Daniel suggested, for carrierroute reload we need double the amount of memory as it holds the old and the new tables until it swaps the pointers (so that the applications doesn't block when reloading the table). Notice the increase in fragments. Sequentials kamctl cr reload does not change the fragments allot. Any ideas? I would recommend using kamailio with at least 1 GB of shared memory. Also monitor the used_size and real_used_size if they are increasing in a `weird` way. The real_used_size might increase because of fragmentation during cr_reload_route commands, but it should not fail, as chunks will be reallocated to other usages of the command.

Hello,
Don't know if this is related, but the statement above hides a nasty
bug: p[1] is a char (as for the description), so is signed, shifting to
the left 16 bits is ok, as an integral promotion takes place. The
problem is that if p[1] is negative (-1 is 0xff), then the integral
promotion is signed as well and is complementary of 2 (or whatever the
implementation considers), and the shift will return another value as
expected.
For example :
#include stdio.h
int main(){
char b = 0xff;
unsigned h = (b16);
printf(%x\n, h);
return 0;
}
will print instead of ff as expected. Haven't calculated
the implication of this related to the bug. An fix would be to cast p[1]
to (unsigned char)

For small number of calls (like your example) the carrierroute module has no way of determining to route on the other gateway.

After looking thru the code it seems that this is the wanted behaviour

From the fixup function of avp_delete :

This flag is sent as the /all /parameter in destroy_avps in usr_avp.c

Any reasons? have you checked if inet_pton() doesn't break the internal ip_addr structure and the use of it? If all is ok, I guess inet_pton() is portable enough through most unix/linux distro's to make use of it. Cheers, Daniel Hello, Even if inet_pton() can't use our existing structure, but it can use an in6_addr structure (size is 16 bytes) that can be easily converted into our internal representation (keep in mind endianess and other constraints). I will have a look when I implement it and will test the changes.

So, to sum it up:
If you want to use IPv6, use $fs instead of force_send_socket() (or
maybe multihoming, haven't tried that yet), and set dns_try_ipv6=yes.
Andreas
Hello,
I have attached an improved version (uses inet_pton instead of manually
parsing the address) of the str2ip6 function that was failing initially.
Can you test it against force_send_socket() with an IP address in the
form [ipv6_address]:port (the [] are mandatory) ?
Thanks,
Marius

This changes the default behavior (no IPv6 default binding), and works for all supported transport protocols (UDP, TCP, SCTP, TLS(over TCP)) The patch is fairly well tested (but not yet in production), and is based on Linux specific RT_NETLINK sockets (for other NIX flavors like BSD the present code works well).

From what I see in the code and documentation, no.
For example this 'carrierroute' table:

Here if ruri is 156xx, and there is no flag set, then the cr module
does not find a match because of the non-zero value in the flag column
(entry 1).
But I want to route this call via carrier1 domain1 and scan_prefix
empty-value entry (entry 2).
It seems that you can't select route 2, but you can select rule 3. For
example
if(!cr_route(default, 1, $rU, $rU, call_id)){
if(!cr_route(default, 2, $rU, $rU, call_id)) #here rule 3
would be selected because domain is 2, not 1
send_reply(403, Not allowed);
}
So you can have a special domain for each carrier that has no flags set
and just acts like a catch all construct. Performance should not be
impacted.
Hope this helps.
Marius
How can I set a default route entry here? Is possible with cr? Now I
only find it possible via a pstn.def_gw_ip variable.
Thank you,
Claudio

Also can you paste the lines from failure_route that are around the cr_next_domain . My suspicion is that you have some calls that reach failure route, but because of some particular cfg lines, they are not correctly routed and the daemon just sleeps in some lines of code on each worker. For replicating the bug and retrieve the line of code where the workers block(as Daniel suggested), it would be better if you decrease the number of worker and keep the same shm memory config value. Marius Shared memory size is 128M and over halv is free just before the error. The server is in production and does handle debug1 well, so I do not have much information in the log files. Private memory is the default size. Any ideas what it could be, or how to investegate further?

As time is not that it would be nice that I have some help :). Also I remember that there were talks last year about a new dialog design and several people work on it.

What Valgrind does it hooks into the memory allocation functions like malloc/calloc/realloc/alloca and keeps track of said allocation. Because, by default, Kamailio uses it's own memory manager (both for private memory or shared), this messes up on how Valgrind can keep track of its allocation/deallocation.

And I've seen several invalid reads and writes (apparently most are off by one). Hello, I haven't used Valgrind memcheck tool for Kamailio , but from what I know it might not be that useful. What Valgrind does it hooks into the memory allocation functions like malloc/calloc/realloc/alloca and keeps track of said allocation. Because, by default, Kamailio uses it's own memory manager (both for private memory or shared), this messes up on how Valgrind can keep track of its allocation/deallocation. It does not make valgrind useless. Basically, it just makes valgrind not detect all errors. Any errors it does detect, should be valid. That is good to know. I don't know if there is a way to make Valgrind to work reliable with K memory managers, but I will take a look on the cases you provide just to be sure. There are valgrind hooks for memory managers. Should probably add them, so it becomes aware of the things. However, those should be only needed for memory pools. Ultimately kamailio uses malloc or mmap to allocate the memory and valgrind knows both. The allocation inside the memory pools, that is what valgrind must be aware of. The first really evil programming mistake I found is at: modules_k/textops/txtvar.c:tr_txt_eval_re() In line 86, it will fills the transformed variable with tr_txt_buf and returns that. However, that is a stack variable, which will get corrupted pretty soon after function return. I'm not sure how to fix this properly. Good call.

So obviously pv_set_ruri_user and others, are called with strings that are allocated for the exact length, and the hacky zero-termination cannot be used in this module. Well, indeed that's a ugly hack. As str's are not 0 terminated, you either copy to a buffer length+1 or you overwrite the memory location next to the end and revert the change afterwards. Not the cleanest way to do it, but from a performance point of view, it make sense. If should be taken extra care to ensure that on every code path the backup is restored.

It's getting nowhere and it's way too complicated to set up, run and support in working code. I call April Fools. :) After realizing this, I started a new standardization project together with my friends in Canada, Simon and Marc, to develop a working solution based on the combination of IPv6 and SIP. We have gotten great feedback and now the IETF, the ITU and the IPv6 forum jointly launches the new standard, SIP-six. From the press release: ”We realize that 99% of the SIP users use SIP for PSTN phone calls. The original SIP standards was written with other applications in mind, a vision that never came true.” said Bob Plug, area director in the IETF. ”That’s why we sat down and said to ourselves that this should be way more simple.” The SIP-six standard totally removes the dependency of domains and URI syntax. There’s no point in using this, since everyone seems to think that IP addressing is more than enough. The new standard use part of the vast IPv6 address space to incorporate the E.164 phone numbers as addresses. This is the reverse of the reverse phone number usage in the enum standard, which is no longer needed in SIP-six. By using IPv6 mobile IP, phone users register their phones and get access to their phone number. Users that need security can easily integrate IPsec into their setup. Media and signalling uses the same addressing scheme and is mixed so that both SIP-six, RTP and RTCP only uses one port address - but in this case a port address with 32 bit subaddress identifying the media stream. This finally solves a lot of the firewall traversal issues that SIP v2.0 had. With the combination of mobile IP and use of public IPv6 addresses NAT traversal won’t be an issue. The testbed for SIP-six has been running for a year at six choosen large SIP carriers, with the assistance of Edvina AB in Sweden and ViaGenius in Montreal, Canada. In an International effort, the testbed is today put in production and Roboid phones all over the world is automatically connected to this worldwide network. You will be able to find out more about it here: http://bit.ly/sipsix SIP-six is implemented as a channel driver in Asterisk 2.0, as a replacement for SIP2.0 in Kamailio 4.0 and a channel module in FreeSwitch - all releases to be released later today.

I have configured kamailio on both systems to be online all the time (using the net.ipv4.ip_nonlocal_bind kernel parameter on the standby server). I have configured kamailio with the listen parameter to be listening on the floating ip addresses only.

Can you confirm that you have a listening UDP socket on the interface that is selected by the kernel for sending the datagram in a mhomed environment. If you are not listening on that interface Kamailio will complain with the error message you received in mhomed=1 config Marius Our requirement, currently is fairly simple, and, I'm thinking that pacemaker/heartbeat/corosync is a little more overhead than required. Ucarp seems to fit the profile fairly well for what we are trying to achieve. I'd like to have kamailio decide on the outbound interface if at all possible, I suspect I would need to delve into all the routing branches if I were to force the outbound socket manually. If I listen on all interfaces and enable mhomed then kamailio transmits on the correct outbound interface, but then uses, what I suppose, is called the primary address associated with the interface. If I were to stay with this configuration, then, would I need to enable the advertised address/port parameters? What about devices behind NAT firewalls, if my advertised address was 1.2.3.4 and the actual interface address was 1.2.3.3 then the NAT'ed UA would see traffic arriving to them as originating from 1.2.3.3 which is not what I am trying to achieve (it needs to arrive in as 1.2.3.4, which is the same address that they registered against. In either case, I would need to set the advertised address based on the destination ip address (i assume obtained by $dd or $rd) so that I can set the appropriate advertised address/port or forced outbound socket. I saw a previous post saying that for mhomed to work correctly kamailio needs to be listening on the interface that is used for the routing of the destination address, this makes sense to me. However, with the carp configuration I have, the virtual address is indeed sitting on the interface that has the destination network configured. I guess Kamailio is unable to decide on which ip address to use on the outbound interface, would it not be possible to have the address used to send, be that of the listen_address parameter even if it is an associated virtual address on the same physical NIC. Or maybe this may be possible with a couple ip rule commands to associate a destination net with a virtual ip address? With corosync/pacemaker/heartbeat, are you able to have kamailio operate on the floating address without haveing to perform the routing decisions for kamailio?

Now if I did something like: ip rule add from 192.168.1.100/32 table 100 ip rule add to 192.168.1.100/32 table 100 ip rule add to 192.168.1.0/24 table 100 ip route add default via 192.168.1.1 table 100 ip route add 192.168.1.0/24 dev eth0 src 192.168.1.100 table 100 ip rule add from 192.168.2.100 table 101 ip rule add to 192.168.2.100 table 101 ip rule add to 192.168.2.0/24 table 101 ip route add 192.168.2.0/24 dev eth1 src 192.168.2.100 table 101 Would kamailio be able to use those interfaces then? Thanks The restriction is from a design/functionality p.o.v. Kamailio must be able to receive a reply (response) on the interface it sends to. So if you can ensure that the kernel will choose one interface that kamailio is bound to, then you are ok, but if it choses one iface that kamailio does not listen, then you have no way of sending the datagram(and that error will appear). I can't really say that the route table will work. One way I used for testing is via Ping or netcat without any local parameters. The choosing of the local address and port is left to the kernel, the same as kamailio with mhomed, so if you can find a suitable routeing table where only the ucarp interfaces are selected then you are ok. Why don't you listen also on 192.168.1.99/192.168.2.99 ?

Hello,
I was thinking of maybe adding a new configurable RR param. A strict
router would copy this header into the RURI. But a.t.m. loose_route does
not perform any checking on tags. Maybe an exclude_uri_tag module param
that can work like this:
modparam(rr, exclude_uri_tag, mark=on);
Then, when the initial SUBSCRIBE (dialog setting message) comes
add_rr_param(;mark=on);
In the loose_route processing, if exclude_uri_tag is set and !(RURI =~
exclude_uri_tag), then perform loose routing on that request (the
request isn't coming from a strict router)
What do you think?

Of course this would require code changes.
A dirty hack would be to manipulate the Route headers manually and set $du.

Hello list,
An UAC sends a resubscribe in the form
SUBSCRIBE sip:al...@example.com SIP/2.0
Route:sip:sip.example.com;lr=on
Route:sip:sip.next-hop.example.com;lr=on
The request has a to tag, from tag... Basic resubscribe(R-URI is the
same as original SUBSCRIBE) The proxy that handles it is a Kamailio (1.5
but this refers to 3.1 as well). The problem is that loose_route()
treats this request as coming from a strict routing router, not from the
UAC, so it applies the strict-to-loose rules and rewrites the request as:
SUBSCRIBE sip:sip.next-hop.example.com;lr=on SIP/2.0
Route:sip:sip.example.com;lr=on
The segment that handles this is pretty standard:
if (loose_route()) {
# sequential request withing a dialog should take the path
# determined by record-routing
if(has_totag()) {
forward();
exit;
}
It sees that message has Route set, it finds the to tag (so the routes
were not a preset), and then , the important thing, sees that the domain
from the RURI matches itself (kamailio has aliases configured for
example.com), thus considering the request as coming from a strict
router. Then it takes the bottom Route header and overwrites the RURI.
What is the best way to ensure that loose routing is applied to the
resubscribe as described above?

could be extended to check if the RURI also cotains lr parameter. If the
lr parameter is not present, this means for sure that the RURI was not
generated by Kamailio.
Hello,
I was thinking of maybe adding a new configurable RR param. A strict
router would copy this header into the RURI. But a.t.m. loose_route does
not perform any checking on tags. Maybe an exclude_uri_tag module param
that can work like this:
modparam(rr, exclude_uri_tag, mark=on);
Then, when the initial SUBSCRIBE (dialog setting message) comes
add_rr_param(;mark=on);
In the loose_route processing, if exclude_uri_tag is set and !(RURI =~
exclude_uri_tag), then perform loose routing on that request (the
request isn't coming from a strict router)
What do you think?
Replying to myself..
Of course, this is almost the same as your idea, the question would this
suffice, of a param to loose_route will be needed to enable/disable this
behavior ?!

Of course this would require code changes.
A dirty hack would be to manipulate the Route headers manually and set $du.

Hello list,
An UAC sends a resubscribe in the form
SUBSCRIBE sip:al...@example.com SIP/2.0
Route:sip:sip.example.com;lr=on
Route:sip:sip.next-hop.example.com;lr=on
The request has a to tag, from tag... Basic resubscribe(R-URI is the
same as original SUBSCRIBE) The proxy that handles it is a Kamailio (1.5
but this refers to 3.1 as well). The problem is that loose_route()
treats this request as coming from a strict routing router, not from the
UAC, so it applies the strict-to-loose rules and rewrites the request as:
SUBSCRIBE sip:sip.next-hop.example.com;lr=on SIP/2.0
Route:sip:sip.example.com;lr=on
The segment that handles this is pretty standard:
if (loose_route()) {
# sequential request withing a dialog should take the path
# determined by record-routing
if(has_totag()) {
forward();
exit;
}
It sees that message has Route set, it finds the to tag (so the routes
were not a preset), and then , the important thing, sees that the domain
from the RURI matches itself (kamailio has aliases configured for
example.com), thus considering the request as coming from a strict
router. Then it takes the bottom Route header and overwrites the RURI.
What is the best way to ensure that loose routing is applied to the
resubscribe as described above?
Cheers,
Marius

Daniel has asked you for some input when compiling with memory debug on (to see if canary values where overwritten by what operations). I have not seen this output yet (don't know if you send it privately to him, or I have missed it on the list). Try to compile again with debug memory support, and set logging to a apropriate level. An idea is to set a special server with a special version of Kamailio. Minimize the number of children (use only one worker) and use just part of the traffic so you have a easier debugging. The bug affects private memory so the number of children should not be an impact. Also you might want to increase the PKG_MEM_SIZE from the default value of 4 MB to something bigger (try 10-15 MB or more). See if this has an impact on the bug (it might be caused by fragmentation in this case a bigger pool might help). If all else fail, I strongly suggest dropping pkg_malloc all together, and using libc's Malloc() instead. This is done at compile time by removing the -DPKG_MALLOC from Makefile.defs and recompiling..

Hi Thomas,
a bit difficult to say on a first sight.. Maybe some scheduling or load issues
on the local machine? I've just checked two production server here, i don't
see it so far in the available logs.
How much load do you've on the machine? And what kind of timeout value do you
specified?
ps. A small change on the server part was done: handle 4 digit carrier

Ah, i see. I guess its not a big change?

On Thu, 10 Feb 2011, Sean O'Donnell (skodonn...@ureach.com) wrote: Hi all, I just started deploying Kamailio release 1.5.4, and I think there's an issue with how Kamailio identifies an outgoing interface when mhomed is enabled under Linux. I use Kamailio as a call distributor/proxy between a soft-switch/SBC and a voicemail platform. It runs on a CentOS 5.3 (Linux 2.6 kernel) host with two network interfaces and is configured such that it listens on both interfaces. One interface (public interface) handles traffic with the SBC, the other (private interface) handles with the VM platform. The 'mhomed' option is enabled. After upgrading from 1.5.3 to 1.5.4, I started noticing problems with UDP packets coming out of the public interface. After looking at some ngrep captures on that interface, I noticed that some packets had the source IP address of the private interface and also had Record-Route and Via headers for the private interface only - no headers for the public interface were there. Usually when I see the wrong source IP in a UDP packet, it's an issue with how routes are set up on the host. However, I had our network engineer double check them, and they seem fine (no ambiguous routes). The fact that I captured these messages on the public interface also indicates to me that the kernel is routing the message correctly. The missing Record-Route and Via for the public interface, however, lead me to believe that the proxy didn't correctly identify the outgoing interface in the first place. After looking at the ChangeLog for 1.5.4, I noticed that the some new logic was put in to improve performance when mhomed is enabled (r5971) in forward.c, and I think this is the issue. As I understand it, prior to 1.5.4, when mhomed was enabled, Kamailio determined the outgoing interface by creating a temporary UDP socket, invoking connect() on the socket with the packet destination, then checking the source IP of the socket that the kernel assigned using getsockname(). After the source address was determined, the temp socket was closed closed. As of 1.5.4, this was modified to reuse the temporary socket and just re-invoking connect() with a new destination address. The problem with the enhancement is that Linux (again, at least in the 2.6 kernels I'm using) doesn't seem to rebind a new source address to the socket when connect() is called more than once on a UDP socket. Instead, it keeps the original one, and thus the wrong interface is assumed. I wrote a small program to confirm this - basically creates a UDP socket, calls connect()/getsockname() multiple times using different destination addresses. I ran it on several 2.6 kernels, including Centos4.x and Centos5. The result was always that the source address of the socket wasn't changed after the first connect(), regardless of the destination address. The only way I could get it work as required was to first do a connect() using a zero'd out AF_UNSPEC address before doing the connect() to the remote address. I also ran it on Solaris and it worked. Go figure. I've downloaded the latest stable release (3.1.2) but I think the issue is still there, and I don't see anything in the user groups that addresses this. Any help would be appreciated.

Or you can use the p_usrloc module that does automatically the db

suite your needs). New in master branch (/shameless advertisement)
But seriously, we might want to give it a try. The config syntax remains

This can be done by forking a copy of the registration request to the backup server, but there are some practical problems in doing this, has anyone do something with this? What problems are you referring to? I use this for some years now without any problems. I checked for some problems here: http://www.smartvox.co.uk/astfaq_ha_failover_ideas.htm Yes - the problem with SIP based replication is that both proxies must be running. This is a problem as Kamailio binds to the virtual IP at start up - thus adding the virtual IP address to the backup server does not make Backup-Kamailio listening to the new IP address - you would have to restart the backup Kamailio. Just bind kamailio to the HA IP on both servers and do REGISTER replication between the two (on SIP level). Then if the IP migrates to the other server, it will take over the rgistrar function with no loss of records. No restart needed. Do you mean that both Kamailio-1 and Kamailio-2 will be as primary server? and the clients will register in the 2 machines? and also they will bind to the ip of the HA? sorry my friend but i do not understand very well, i'm quite new with redundant systems, could you please explain a little? Hello This week, I have added the p_usrloc module to K master branch, that allows partitioned user location service for Kamailio. This has the benefits of redundancy, failover and load balancing to user location service for K. Along with Henning Westerholt, we will also present some strategies for partioned user location to the upcoming FOSDEM meeting in Brussels.(more info here http://www.fosdem.org/2011/schedule/event/kamailiolocationservices) You can check the README of the module (master branch modules_k/p_usrloc) for some strategies for partitioned user location. Marius I think most people either have a database (which is highly-available by itself) which is used by both proxies, or every proxy has a local database and the synchronization is on DB level (e.g. master-slave replication, btw: does somebody know if usrloc DB queries are suitable for master-master replication?) Last time i tried, they are not, at least not in writeback mode. One proxy is expiring records from the DB which the other proxy is trying to update. Maybe DB-only mode will work, but that has some practical (performcance) problems. -- Greetings, Alex Hermann ___ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org mailto:sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users -- Ing.

just checked the source..
int th_skip_msg(sip_msg_t *msg)
{
if (!get_cseq(msg)) {
LM_WARN(Invalid/Unparsed CSeq in message. Skipping.);
return 1;
}
if((get_cseq(msg)-method_id)(METHOD_REGISTER|METHOD_PUBLISH))
return 1;
return 0;

Hello Brian,
Module: sip-router
Branch: 3.1
Commit: a72e59d23d4b104af6d7f30d1dc02a5fe175f3af
Also master and 3.0 are checked. the patch is this simple check for
messages that don't have a correct CSeq header.

Re: [SR-Users] Recursive failure_route after CFNA
On 12/21/2010 03:22 PM, Igor Potjevlesch wrote: Hello all, I have setup a mechanism to forward outgoing calls to another gateway if the first one replies with 5xx. I have simply used ‘t_check_status’ in the failure_route. This works. But, with a CFNA it doesn’t work : the incoming call is treated by SER (0.9.9). After the timer has expired the call goes to ‘failure_route’ for the first time to setup the CFNA with, finally, an ‘append_branch’. At this moment, the first gateway replies with 5xx and the call never goes to ‘failure_route’. I can match the 5xx within the ‘onreply_route’, but that’s all. So, instead of trying another gateway, the initial incoming calls terminate on the voicemail. Can anyone help me?

Re: [SR-Users] VIA header x-route-tag
Hello Alex,
Can't test it right now, but it should work better with this :
$var(s:xroutetag) = $(hdr(Via){re.subst,/^.*;x-route-tag=(.*)/\1/})
You want to substitute (only affects $var) the whole via header with the regex
found between () and referenced by \1. Keep in mind that Daniel's solution is
more elegant and should work for you.

Re: [SR-Users] Failover with SRV records
On 11/29/2010 06:03 AM, Eric Hiller wrote: Sorry all for the second question of the night as I go through working out bugs in my setup. I want to use SRV records to loadbalance across hosts. This works great, when all the hosts listed in the SRV are up. However, I want kamailio to use the next host if the current hosts fails. I tried just setting up a new branch, but kamailio keeps using the same SRV entry over and over on that transaction, only a new transaction seems to give kamailio a chance to use a different SRV entry. Any ideas as to how I can force kamailio to try the next SRV entry if the first one fails? For example I t_relay to 2.domain.com which has a _sip._udp.2.domain.com entry for hostA and hostB. If hostB is down, but kamialio decides to send to hostB it just keeps doing so even though hostA is perfectly up it doesn't try for it. Is there a way to remove hostB from the kamailio try list? Or as an alternative to do a manual SRV lookup on 2.domain.com and then put then in a variable and go through them one by one manually? Ideas? Thanks -Eric Hello, Kamailio does not use ICMP replies to check if a host is reachable on a UDP sendto(). This means that ICMP port unreachable errors are not handled by K and so the same host is retried on TM retransmits. Host selection of both A records and SRV records is done based on weights returned from the DNS query(so it is balanced) For a INVITE you can use fr_timer to very low values (5 seconds) and fr_inv_timer to larger value. If no 100 is received than the fr_timer kicks in and depending on the disable_dns_failover core parameter another host is tried. The order of retry is this: Regardless of disable_dns_failover param, other A records are tried (if no 0x4 flag is given to t_relay (at least in K1.5)), then , is dns_failover is active, other SRV records, then NAPTR. Check the TM documentation for more info. Marius P.S. This is on K 1.5 . I hope 3.0/3.1 still has this . I think dns caching has changed so you need to recheck the parameters I gave. ___ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users

This means that ICMP port unreachable errors are not handled by K and so the same host is retried on TM retransmits. AFAIR using raw sockets checking ICMP notifications would be possible (not yet implemented, but possible as I remember from a thread with Andrei). Possible, but not easily implementable, as ICMP Host unreachable are sent asynchronously from the kernel. Also the current sendto() call does not guarantee delivery on all Unixes (Linux should be fine), connected UDP sockets are to be used instead. IMHO this would be very useful because if a UDP port is unreachable and there is a ICMP notification about it, the proxy should generate an internal 503 (transport error) rather than a 408 (fr_timer timeout). Well, this means that we should disable dns_failover (or equivalents) completely and handle ICMP errors in failure_route blocks(just test if the transaction issued a 503). If I recall RFC 3263 , this would mean another server discovery (as the new request generates a new transaction) so again there is the possibility that the broken host is selected. If we use this dns fallback(IMHO this is a nice feature- I personally rely on this) how do we decide to generate a 503 ? If the host is already a IP address, that it would be ok to send a 503, as no DNS failover is possible. Ideas?

Yes I think it is
Looking at the debug messages I see the CSeq is wrong.
But :
int th_skip_msg(sip_msg_t *msg)
{
if((get_cseq(msg)-method_id)(METHOD_REGISTER|METHOD_PUBLISH))
return 1;
return 0;
}
As the cseq is wrong the get_cseq macro probably returns a NULL Pointer
who gets dereferenced (BANG the crash). Any other Ideas ?!
The patch is trivial ( if(!get_cseq(msg))) parse_cseq() ) something
in this line. Daniel, What do you think ?

In Dialog... if one of the endpoints is a B2BUA, it can send at specific interval in-dialog OPTIONS ping (OPTIONS request, increasing cseq) to the other endpoint. Most well-behaved UAS will respond with a 481 if the dialog not longer exists as per RFC 3261 . The response to an OPTIONS is constructed using the standard rules for a SIP response as discussed in Section 8.2.6. The response code chosen MUST be the same that would have been chosen had the request been an INVITE. Other error conditions are on a 408 , 404 etc (as any in-dialog request is not guaranteed to succeed). This is already used some production environments. 2. Out of dialog. A proxy keeps sending OPTIONS request (no dialog involved here) to one of the UA as long as one of these 2 conditions exist: a. the dialog has not ended via a method specific mean (BYE for INVITE etc) b. a 408 (or other error codes) was received when generating a BYE. These where the big two points of the draft.

Hello
You might want to use loose_route() to perform loose routing (defined in
RFC 3261) of in-dialog requests. (Loose_route also performs strict routing)
if (has_totag()){
loose_route();

exit;

Re: [SR-Users] Reverse Filterlists idea
On 10/18/2010 07:09 PM, Nicolas Rüger wrote: Hello, Marius Zbihlei has patched the userblacklist module, so that it can handle characters as well (NOT in main release 3.1 yet). Thanks Marius. Therefore it might now be possible to filter general SIP-URIs!?? My idea is simple and described here. Please give some Feedback!!! As the prefix-functionality up to now was referring to SIP-URIs consisting of digits (=real telephon numbers) like 004930123...@1and1.de the general URI might be something like user_...@server.domain.de So far the prefix-functionality works because usernames that are real telephone numbers, that always start with country-code, followed by town- or regional-code and end with a unique number of the user (in this example 0049=Germany, (0)30=Berlin, 123456=user's unique number). To use prefix-functionality with general (including non-digits) URIs it must be evaluated reverse (from back to front) as the domain ends with the country- or top-level-domain and becomes more detailed the reverse way. Hello, I understand your need, and it seems a fairly good feature request. I have a few worries. I don't agree with evaluating everything in reverse. I think usernames are to be evaluated in normal order, and only domain(DNS part), if present should be evaluated in reverse. So when trying to match user_...@server.domain.de (as prefix field) it should be matched by either user_12 or .domain.de . Wouldn't this make more sense? What do you think? So the IDEA is: Insert the domain as prefix in userblacklist-table in reverse, to use the functionality. I would use a perl-script to reverse the SIP-URI of the calling party in routing logic and then check it against the already reverted domain in the userblacklist-table. Do you think this is a good/well-working idea??? This looks to me like a hack. I was thinking that the userblacklist module should better provide this match instead of the script writer hacking with some perl. I direction parameter might do the trick, but this will require some big changes to this and dtrie. This also affects every module that uses dtrie in its implementation like carrierroute and so on(They all do prefix matching). As Henning W. already said in the previous thread, until now there wasn't much need for doing this, as interoperability with PSTN caused using a user scheme resembling classic telephony.

Hello
You have to apply both patches , the original one (that introduced the
new feature) and the bugfix.
Marius
Can you fix that, please?
Thank you.

Hello Marius,
thanks for the advice. I forgot about the modparam. It seems working now
as I don't get the error any more :)
BUT blacklisting does not work for mesee:
In kamailio.cfg I added the following in routing logic:
if (is_method(INVITE)) {
if (!check_user_blacklist($rU, $rd,$fU)){
sl_send_reply(403, Forbidden);
exit;
}
}
Im my case $rU is user04 , $rd is mykamailio.de and $fU is user03.
...means use...@mykamailio.de is calling use...@mykamailio.de
Table userblacklist looks like this:
Hello
You are right, I have never tested with $fU given so I was a bug in the
code. It should be fixed by commit
d128ac966beeb2ddfd3332a20fdd93ae292d81b1. The bug affected alphanum
match mode only if the $fU had trailing non-digit chars.
Can you check if it works...
Thank you.
Marius
id | username |domain | prefix | whitelist
15 | user04 | mykamailio.de | user03 |0
In this scenario user03 should be blacklisted by user04, right!? But
it's not...
Any ideas why???
Thank you.

Hey Marius,

Picking the cherry worked without the -depth 1. :)
BUT I still get an error when using userblacklistmodule:

Hello,
Are you sure that you rebuilt userblacklist module after the patch (you
can go to modules_k/userblacklist and run make from there)? Did the
patch applied without error? Also, have you explicitly enabled the
alpha
numerical match mode
modparam(userblacklist, match_mode, 128)
in you cfg file?
Cheers
Marius
The username I use in userblacklist-table is user04 and the prefix
is
user03. Domain column is empty.
Any ideas why it's not working???
Thank you!!

Hello,
Sorry for the advice, -depth 1 means no commit history which is fine
:D
The patch I was referring is here
http://git.sip-router.org/cgi-bin/gitweb.cgi?p=sip-router;a=commitdiff;h=2f8f8e58a922adec440d47592d1ca24dbf05f29c
You can save it into a file (starting with the line diff --git
a/modules_k/userblacklist/README b/modules_k/userblacklist/README)
and
use the patch
utility to patch the module.
Then compile.

Kamailio tries to parse the first line of the message, which is the request line of the type METHOD RURI SIP/2.0, but it can't understand the data it receives. It the data is sent from one (broken) host, you might want to block this at a firewall level. Perform a tcpdump on port 5060 (or the port k is using) and check if this applies.

Thank's for the answers.
Based on your explanation, I think that the problem is an external library.
The kamailio process is taking all the system memory.
When the system runs out of memory, it kills kamailio.
But how can I find out what is the library?
This means that either the library is buggy, or the library is used
wrongly (e.g. not releasing buffers ...). Let's take a look at your modules:
loadmodule maxfwd.so
loadmodule exec.so
loadmodule tm.so
loadmodule sl.so
loadmodule dispatcher.so
loadmodule textops.so
loadmodule xlog.so
loadmodule mi_fifo.so
loadmodule pv.so
I think they do not use any external libraries
loadmodule regex.so
This one uses libpcre. Maybe there is a problem with the regular
expressions?
Hello again,
There seems to be a memory leak in w_pcre_match . I have fixed it in
commit 61f4d7f. Please compile with this patch and test (applied to git
kamailio_3.0 branch)
Marius
Hello
I have some suggestions
# excessively long display name
if (!pcre_match($fn,^.{0,62}$$)) {
sl_send_reply(403, Forbidden - Display Name Max Size
Exceeded);
exit;
};
this will be much better handled by a transformation
if ( $(fn{s.len}) 62 ) {...}
Make this change and see if you still have problems with OOM Killer
Marius

If you have a dump of the memory distribution, can you spot anything out of the ordinary. As a tip look for functions in the ending part of the dump that repeat for multiple times. The lower offset is usually alloc'ed during module initialization so any big leak will happen at higher offsets (I don't know if this is the rule but this is what I observed). Have you tried increasing the memory pool?
