Summary: Tomcat Connector:JK/AJP: JK Status Worker accesses freed
memory for NSAPI plugin
Product: Tomcat 4
Version: 4.1.31
Platform: Sun
OS/Version: Solaris
Status: NEW
Severity: minor
Priority: P3
Component: Connector:JK/AJP
AssignedTo: tomcat-dev@jakarta.apache.org
ReportedBy: [EMAIL PROTECTED]
For release 1.2.13 of jakarta-tomcat-connectors:
Problem 1: the NSAPI plugin under root/jk/native/netscape/jk_nsapi_plugin.c
frees() the initial workers map structure, init_map, at the end of the jk_init
(...) function. As the jk_status.c worker uses the list of workers stored
within this structure, when the jk_status worker is used by the NSAPI plugin,
it attempts to read freed memory.
Problem 2: the NSAPI plugin under root/jk/native/netscape/jk_nsapi_plugin.c
does not use the uri_to_worker map within the jk_worker_env_t structure (as
this is done inside the netscape configuration files), however, the jk_status
worker attempts to access the (uw_map) attached to the current jk_ws_service
without a null check, thus causing the jk_status worker to attempt to
dereference a null pointer.
Attached is a diff output of the changes between the jk_nsapi_plugin.c supplied
within the jakarta-tomcat-connectors-1.2.13-src package, and a modified version
of this file which fixes this problem by adding a uri_to_worker map, and having
a static init_map structure:
---
56,57d55
static jk_map_t *init_map = NULL;
static jk_uri_worker_map_t *uw_map = NULL;
89c87
init_map = (jk_map_t *)init_d;
---
jk_map_t *init_map = (jk_map_t *)init_d;
93,101c91
if (uri_worker_map_alloc(uw_map, NULL, logger)) {
uw_map-fname = ;
worker_env.uri_to_worker = uw_map;
init_on_other_thread_is_ok = JK_TRUE;
}
else {
jk_log(logger, JK_LOG_EMERG,
In init_workers_on_other_threads, failed);
}
---
init_on_other_thread_is_ok = JK_TRUE;
227a218
jk_map_t *init_map;
271a263,264
jk_map_free(init_map);
289,292d281
if (uw_map) {
uri_worker_map_free(uw_map, logger);
}
297,300d285
if (init_map) {
jk_map_free(init_map);
}

The values of properties, worker_env.worker_list stores just pointers to the property map. After the property map is free'd the pointers are invalid. This crashes if one tries to list the workers with the status worker. Solutions: 1. copy the values (need proper allocation and freeing mem many places) 2. keep the map during the whole lifetime of the ISAPI filter The patch I attached uses the second solution.

Well, I was thinking to use it as foundation for the windows http.sys. But who knows what the next windows generation will offer. Since the development would take much more then next WIN-xx release, and since it would be a WIN only, there is no need to use the APR, so again probably useless.

mod_jk 1.2.14-dev testing status report
Tested mod_jk 1.2.14-dev with nb_connect() and setsockopt() enabled for NetWare in jk_connect.c: (all testing on NetWare 6.5 SP3 and SP4) 2.0.52 and Tomcat 4.1.30: build correctly and stress tested, 2.0.54 and Tomcat 4.1.31: build correctly, stress and functional testing done, 2.1.x: build correctly, 1.3.33: build with minor tweaking to environment and makefile, stress tested with UP version of Apache. Crash with MP version of Apache (unsupported, so not a problem), 1.3.head: build with same minor tweaking as with 1.3.33. The tweaking to build with 1.3.x might need to be fixed in the future, but it is a low priority item for me. Next week, I will try to push 1.2.14-dev in our official build in order to get it exposed to more testers. The ap_rflush() changes speed up our download rate by a factor of three on large files (700MB), this is cool. Thanks, Jean-Jacques

I think you might get into the problems with shared memory (particularly on unix) because some child might have a different idea about shared memory addresses. If you do not delete any worker and add new one at the end of the worker.list it might work. Anyhow it's not something I would use in the production and rely on its proper behavior.

Oh - so this is a bug/design flaw in mod_jk? Does the same affect the prefork/worker MPMs? One aspect is inheritance of handles (e.g. handle to SHM segment). I've always ment to make that more generic, and it would be nice to solve for Apache 2.2. It's used now to hand of the score and listener handles from the parent to child. The trivial solution is to use an anon segment which Win32 will not inherit, which means that SHM is unique to a single generation, and won't be polluted by changes in another worker. This does sound like a good use case, though, for handing off memory segments, mutexes and so forth to child processes. With a pointer or two, I'll be happy to look at it.

Problem with WIN32 is because the closing child and new child will not share the worker data during restart, so you will loose the statistics during restart. With unixes the problem is because the workers are allocated according to the worker.list and balance_members. If you change those lists in the config on restart the child processes could have different shared memory segment addresses. Like said if you only add to the end of list then everything will probably be OK. To resolve that we would actually need a database like shared memory with worker name as a key.

Re: Graceful restart on Windows [was Re: Adding working dynamically with mod_jk status?]
Hi, I use Apache httpd, mod_jk and Tomcat 5 under Linux. Re-staring Apache httpd alone should never be a problem. However when I re-start Tomcat, then I follow this sequence: - Stop Apache httpd - Restart Tomcat - Start Apache httpd I follow this sequence because mod_jk returns a server error if it cannot connect to Tomcat. In order for this to work, the Tomcat restart operation must truly block (no timeout guessing workarounds here, please) so that the last step Start Apache httpd does not start before Tomcat is running again, and that there is no time wasted in the Restart Tomcat step.

And a new child is kicked off to serve all future incoming requests.

Yes, it should be possible on Windows as well. You may have to invoke apache.exe manually on that platform, I am not familiar with Apache on Windows.

Unclear 5.0 release status
Hi, the release status of TC 5.0 is a little unclear: http://jakarta.apache.org/tomcat/tomcat-5.0-doc/status.html states: Tomcat 5.0.29 was released on October 6th, 2004. Work on the 5.0 branch is primarily for maintenance and bug fixes. It is still considered the best branch for production use, but Tomcat 5.5 is rapidly nearing a stable release. I remember, that 5.0.29 was not finally released, instead 5.0.30-beta was put on the server 6 months ago and never changed from beta to final, so http://jakarta.apache.org/site/downloads/downloads_tomcat-5.cgi still only shows 5.0.30-beta and the last non-beta version is 5.0.28. Any reasons to not formally change 5.0.30 from beta to final (apart from everyone is using his/her time for 5.5.x)?

I am not sure that o.a.c.ant is really the correct package for those connector ant task I don't know. I'd say it doesn't look too bad, and ease of packaging wins. What are the planed feature for the new host manager tool? Have you see the Centaurus-Platform (http://centaurus.sf.net) Management Console from Thorsten Kamann?. No. I went to see it, and I have to say I don't speak german at all. The download is kinda huge, BTW. OK, all docs are in german, but install it and look at http://localhost:8280/management the very great admin tool. Dowload it at http://prdownloads.sourceforge.net/centaurus/centaurus-platform-1.0beta6-full-gui-installer.jar?download That's cool, but I'll never be able to do anything with it ;) Rémy - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Release status ?
Hi, This week, I will work on adding the host manager tool that I promised long ago. As 5.5.8 is in limbo, I think we should plan for a 5.5.9 instead. Or is there still some interest in that build ? Last, did anyone test the new logging defaults ? Thanks :) Rémy - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

First look at new mod_jk status page
Hello Mladen, new status page work fine. Really cool ;-) Only the type of a workers was currently not correct displayed. I got unknown as value. opps! Is it planned that we can save the worker configuration as seperate workers.properties? How we can transfer the information to an Tomcat MBeanServer? Can I help to fix the old Java AJP jk2 handler or start with a new implementaion? Can we get the status information as XML document? Not really important but easier to integrate in some monitoring products. What are your next steps?

to elaborate a bit more my thoughts on the kind of stats would be useful from a monitoring perspective * system load * system freeram * system total ram * system free ram * open connections * # of connections timed_wait I'm sure are other stats that are useful.

It works really well, and it's the easiest to maintain and fastest of all JNI flavors I've seen. Exactly. IMO the SWT from Eclipse proved to be as effective and easy to use as any other Java package or library. And that is what I have done with my apr-java. Right now I've implemented it using the org.apache.apr.native with the Library, Pool, Error, File, Mutex, Mmap, Shm, Socket and Pollset as containers for specific APR functions with exactly the same function prototypes. The wrapping code is really minimal, and in lot cases done as macros. I did not tried to wrap the code that has better or direct implementation in Java like string, thread, etc... Also the project does not prevent that we add any additional functionality not present in the APR.

Things like true shared memory, process mutexes, advanced networking, pipes, etc. that are missing from the core Java will be supported. Usages are many, like writing high-performance networking connector for Tomcat, making Tomcat a Apache mpm-like server with multiple JVMs, etc... I hope I'll have a working start point this month, so we could discuss is it worth the effort at all, would it fit inside JTC, commons, or to go trough apache incubation as a separate project.

Re: adding features to Status servlet
Why don't you check in some of this to j-t-c or some 'proposal' area ? AFAIK apr has a lot of functionality, but not everything is included. It would be nice if it is not limited to apr. Usually with JNI the hardest part is to build, distribute and then set it up and debug ld_library_path issues. If you do it for one library, it's easy to add more.

Re: adding features to Status servlet
hehe, well if it was just a simple JNI calling sysinfo, I would agree it would have limited lifespan. But considering how slow some people move, it would last atleast 3-4 years, which is still useful in my mind. given that mladen is working on apr-java, I would say it is more useful and would have a significantly longer lifespan. everything has a life span, but if it is useful, than i feel it's worth while. plus it's my own time, so not like anyone else is going to care if it only lasts for 2-4 years. I much rather have the option of using it with jdk1.4 and across all VM's than simply relying on Sun's jdk5. peter On Tue, 4 Jan 2005 04:46:48 + (UTC), Kevin Offet [EMAIL PROTECTED] wrote: Peter Lin woolfel at gmail.com writes: right it is available in JDK5, but not everyone can use jdk5 :( I know plenty of people who are still using jdk1.3.1 and plenty are just moving to jdk1.4.2 now. many of the features are available in jdk5, but I believe what mladen is working on is beyond what jdk5 provides.

Anything that allows Java to do things only native apps can do instead of beeing as dumb as the dumbest platform is worth the effort :-) JTC already has some apr and jni code ( it is true, using the dead jk2 model ), why not start there and if it grows big enough move to commons?

IMO the SWT from Eclipse proved to be as effective and easy to use as any other Java package or library. And that is what I have done with my apr-java. Right now I've implemented it using the org.apache.apr.native with the Library, Pool, Error, File, Mutex, Mmap, Shm, Socket and Pollset as containers for specific APR functions with exactly the same function prototypes. The wrapping code is really minimal, and in lot cases done as macros. I did not tried to wrap the code that has better or direct implementation in Java like string, thread, etc...

Re: adding features to Status servlet
that's why I decided it was a good idea to ask for other's thoughts. From a stress testing perspective, I find system load stats very valuable. breaking tomcat isn't something I find desirable either, but there has to be a better way to measure system load other than ssh into the server and use top. manually doing top or sysinfo is fine for load testing, but for performance monitoring, something automated is desirable. My thought was to make it optional and have it detect whether or not a native lib for that platform exists. If it doesn't it would affect the status servlet and would look exactly the same as it does now. on the otherhand, if the user enables it and a native lib exists, it could display the system load. the only other option is to lobby Sun to add system load stats to the VM, so that it is portable across platforms. peter On Fri, 31 Dec 2004 17:27:03 -0500, Frank W.

Re: adding features to Status servlet
As implementation - I assume you weren't going to add a native method and a .so library to the standalone tomcat distribution :-) Adding capability to StatusServlet to report arbitrary mbean attributes would make this feature easy to add ( there is some code in JmxProxyServlet - but it it would be much better if integrated and made consistent with the status servlet ). For the JNI + mbean implementation - it may be better to use a separate component ( I don't see why it would be specific in any way to tomcat - any jmx-based app could use this ). There are several other OS-specific informations of interest ( including in Windows ), JMX is designed exactly for this - to expose management info for different systems.
