Package deletion then have to restart web configurator
I am now on nanobsd:
built on Thu Jul 5 02:36:34 EDT 2012
After deleting a package I no longer get any response from the web interface. The package deletion finishes fine with the usual set of messages, for example here is a simple cron deletion:
Backing up libraries... Removing package... Removing Cron components... Tabs items... done. Menu items... done. Services... done. Loading package instructions... Deinstall commands... done. Removing package instructions...done. Auxiliary files... done. Package XML... done. Configuration... done. Cleaning up... Package deleted.
Any attempt to navigate to another page or type in the router address to start at the beginning again just times out.
I go to a console session and restart the WebConfigurator and it works fine.
Package installs do not have this problem.
I can't see anything nasty in the system log or in /tmp/PHP-errors.log
I have noticed this since the July builds, after the big rebuild when there was a 48-hour gap between snapshots. But I can't guarantee that that is exactly when it started.
The problem is very easily reproducible on my system - just install something small and quick like cron, then delete it.
I'm not sure exactly where to look to debug this one.
I've been installing and uninstalling packages like crazy the last couple weeks and haven't hit anything like that yet.
Sure that nothing shows up in the system log after that? (The log would be wiped on a reboot, so you'd have to check over SSH)
And if it is always the same package then please post the package.
I have seen the problem with Cron, pfBlocker and bandwidthd - a couple of easy to install and remove packages. But the problem seems to be per-system. I have 6 Alix 2D13 nanobsd systems running 2.1, all on July builds. I went to every system and installed cron then removed it. 4 systems have the problem, 2 don't. All the systems have combinations of OpenVPN servers and clients doing site-to-site shared key OpenVPN. 2 systems are just ordinary WAN/LAN - both of those have the problem. 2 systems with WAN/OPT1/LAN have the problem, 2 systems with WAN/OPT1/LAN do not have the problem. The 4 systems with dual ISP access (WAN+OPT1) have default gateway switching on and gateway groups to feed LAN traffic into. In all 4 cases the OpenVPN clients are on LAN and go out the default gateway. All that stuff is working fine. I am struggling to see what is the common difference between systems with and without the problem.
The system log does have nasty errors in it - here are 2 examples of the 4 systems that do this:

All the hardware is the same - 2GB CF cards, 256MB Alix boards. I can't believe that 1 have 4 out of 6 systems with a similar hardware issue.
I removed all the OpenVPN and DynDNS stuff from my test router. It still has the problem! I guess I will flash another CF card for the test router and see how it behaves.
If anyone else has experienced this issue I would love to hear about your logs and config.
Could this be a problem of read/write access on nanobsd systems in the install/deinstall routine ?
But this would not explain why it works on some and not on others…
Yeah that's definitely a nanobsd issue.
I think there is still a ticket around for that very problem, happens on 2.0.x also, though I've only ever seen it after a firmware upgrade, not normally from installing a package.
Got another example of this just now. The nanobsd system is running the snapshot from 20120727-1520.
This system had never had any package installed. I installed blinkled, rebooted to test that the pbi db survived the reboot, then removed blinkled. Now the Web configurator does not respond. The system log has:

I can't see anything in /var/log/* that logs the package removal - as an aside it might be nice if there was somewhere that package installation and removal is logged (maybe it is already).

I will leave it this way for a while. If anyone has suggestions for more data to collect then I can do that. Or even find a way to let someone access it remotely if that would be any help to those who can try and track this down. You never know, if this is fixed then similar things that happen on the initial boot and package reinstall after an upgrade might also have the same fix?
Been chasing that for years… never have been able to narrow it down myself.
Since the mount ro/rw calls use a shared memory reference, perhaps some digging with ipcs might help:
fetch -o /usr/bin/ipcs http://files.chi.pfsense.org/jimp/ipcs.i386 chmod a+x /usr/bin/ipcs rehash
And then check the output of:
ipcs -m ipcs -pt ipcs -T
Might not hurt to compare the output from that when it's running normally (/ is read-only, after a reboot with no pkg operations) and then again when it's in the crashy state.
For the record. here is the output in the broken state:

Now to contemplate what to try/collect next before rebooting and real-time data is gone.
It seems odd that blinkled appears in the list of processes that sig11:
Jul 30 18:11:49 test02 kernel: pid 2722 (blinkled), uid 0: exited on signal 11 Jul 30 18:11:49 test02 kernel: pid 2252 (blinkled), uid 0: exited on signal 11
To me, that means either:
a) The sig11 is happening before blinkled is stopped and the package removed; or
b) The blinkled package is getting removed, but the process/es are not stopped first - somehow having the proverbial rug pulled from under them, their executable disappears from storage while they are running in memory.
Edit: From status services I couldn't get blinkled to stop and start, so there seems to be some problem with the stop/start code for this package.
Here is 1 problem with the shared memory reference count implementation in /etc/inc/util.inc
The data in the shared memory is actually string data. The PHP routine shmop_write just writes a string to the shared memory, with no null terminator or anything. 0 becomes "0" in the first byte, followed by whatever happened to be in the following bytes of memory. If the reference count goes from 9 to 10, the memory goes from "9 " to "10". When it is decremented, 10-1=9, "9" goes in the first byte, the second byte stays "0". Next time the value is looked at, it returns "90"! This is a recipe for getting the reference count wrong and thus it never returns to zero. When that happens, conf_mount_ro will not actually re-mount read-only - it only switches back to read-only when the reference count goes back to zero.
The attached bit of code calls refcount_reference and refcount_unreference in a way that demonstrates the problem. You can just save it somewhere and run it from the command line to get:
[2.1-BETA0][firstname.lastname@example.org]/var/log(117): php shmop_demo.php Content-type: text/html refcount_read: 0 refcount_reference: 1 refcount_read: 1 refcount_reference: 2 refcount_read: 2 refcount_reference: 3 refcount_read: 3 refcount_reference: 4 refcount_read: 4 refcount_reference: 5 refcount_read: 5 refcount_reference: 6 refcount_read: 6 refcount_reference: 7 refcount_read: 7 refcount_reference: 8 refcount_read: 8 refcount_reference: 9 refcount_read: 9 refcount_reference: 10 refcount_read: 10 refcount_unreference: refcount_read: 90 refcount_reference: 91 refcount_read: 91 refcount_reference: 92 refcount_read: 92 refcount_reference: 93 refcount_read: 93 refcount_reference: 94 refcount_read: 94 refcount_reference: 95 refcount_read: 95 refcount_reference: 96 refcount_read: 96 refcount_reference: 97 refcount_read: 97 refcount_reference: 98 refcount_read: 98 refcount_reference: 99 refcount_read: 99 refcount_reference: 100 refcount_read: 100 refcount_unreference: refcount_read: 990 refcount_reference: 991 refcount_read: 991 refcount_reference: 992 refcount_read: 992 refcount_reference: 993 refcount_read: 993 refcount_reference: 994 refcount_read: 994 refcount_reference: 995 refcount_read: 995 refcount_reference: 996 refcount_read: 996 refcount_reference: 997 refcount_read: 997 refcount_reference: 998 refcount_read: 998 refcount_reference: 999 refcount_read: 999 refcount_reference: 1000 refcount_read: 1000 refcount_unreference: refcount_read: 9990
There is 10 bytes allocated for this shared memory section, I guess other bad things happen after this sort of process causes the ref count to exceed 10 digits. Also the initialisation just puts a "0" in the first byte. I think there is the potential for the other 9 bytes to be random rubbish at startup? Which could cause really hard to track and reproduce problems.
I'll have a go at fixing this up better - it might solve the issues with nanobsd systems getting left in RW after package installs etc. I can't see how it would solve the slow switching back to RO though, but who knows?
Edit: I rebooted and monitored the ref count in memory while installing and removing blinkled - it just went 0, 1, 2, 1, 0. But the same problem with a bunch of sig11 process exits. So I don't think fixing the ref count issue described here will fix the sig11 exits.
Well I committed a fix for that, but it didn't help the crashes.
I applied your changes and they fixup the ref count issue if it gets big. But the problem is still there - from my monitoring the ref count only goes to 2 anyway.
Interestingly, I was using a little script to show me the ref count, and while removing blinkled it even gave me a segmentation fault. Also, the blinkled processes hung around a long time after the removal script had said that the pbi was deleted, I guess running in memory without looking to read pages out of the file on the CF card. They even survived after the segmentation fault that I got interactively.

In /etc/inc/pkg-utils.inc function uninstall_package I commented out:
// exec("/usr/bin/tar xzPfU /tmp/pkg_libs.tgz -C /"); // exec("/usr/bin/tar xzPfU /tmp/pkg_bins.tgz -C /"); // @unlink("/tmp/pkg_libs.tgz"); // @unlink("/tmp/pkg_bins.tgz");
This stuff is backed up earlier in the routine and then restored for some reason.
But it includes things like /usr/local/lib/php/20090626 which has a bunch of "so" files related to php.
With this restore commented out, I don't get the sig11 crashes, the web configurator stays available.
I wonder why lots of stuff from /usr/local/lib is being backed up and restored during every package uninstall?
The "so" files would go missing for a moment as "tar" deletes the original on disk and then restores the one from backup.
That was next on my list of things to try but had some customers to attend to.
The libraries are backed up in case a package removed a file that was required for the system to function properly. The restore process could probably be tweaked a bit somehow though.
I made a couple of pull requests, which Seth has committed, to make the reference count in the shared memory section even more robust - locking it while it is incremented and decremented. Hopefully now as long as all code does actually call conf_mount_rw folowed by conf_mount_ro after it has finished changing stuff, the filesystem will always end up read-only again on nanobsd.
Also tidied up an unnecessary rw then ro mount in pkg-utils which was slowing things down every time the user navigated to System:Packages and it listed Installed Packages.
This is all good stuff for nanobsd in general, but it doesn't fix the sig11. To fix that I still need to comment out the file restore from pkg-utils.inc:
// exec("/usr/bin/tar xzPfU /tmp/pkg_libs.tgz -C /"); // exec("/usr/bin/tar xzPfU /tmp/pkg_bins.tgz -C /"); // @unlink("/tmp/pkg_libs.tgz"); // @unlink("/tmp/pkg_bins.tgz");
Now it needs someone like JimP who has the big picture, to work out how best to trim down this restore - maybe can do a comparison, work out if anything essential has gone missing, and only put the missing things back?
I'm going over that with the other devs.
The problem is likely the U flag to tar, which unlinks files before restoring. I wager if that were removing, and even better if "k" was put in its place, it may behave better.
"k" would cause it to keep existing files, and since this is restoring a backup after files were removed, that seems to make more sense to me. I'm just not sure if there are any edge cases I'm forgetting that required U to restore properly.
If the pkg uninstall corrupted the file, U would be better… but I'm not sure if that was one of the reasons.
A quick test of this on NanoBSD is promising. Without U, but with k (just replaced U with k in the tar command), the GUI is fine and everything seems happy.
The blinkled process still crashed but since it was uninstalled I expected as much.
Not sure how that might help/hurt a full install. I've got a discussion started with the other devs to see if I'm missing anything there. More testing would be appreciated before I commit it.
Good news - I did various install/uninstalls with the new code and there are no problems. webConfigurator keeps running fine, no sig11 (apart from blinkled, which is a different issue).
Installed the following:
openvpn client export utility
then did a firmware upgrade to the build that just finished:
built on Tue Jul 31 19:07:11 EDT 2012
All went well. It reinstalled all the packages and the webConfigurator stayed up. After the package installs were finished all services were running, openvpn link up, web browsing from client… working.
During the package installs it does a package removal first for each package. That now spews out a lot of "file exists" messages from the tar restore with k option, but it works.
I guess the package removal is just in case, but if the code could detect that it is a package install from the first boot after a firmware upgrade then it could know that the package removal step is not needed.
I have attached a log of the serial console output for the record.
Looks like we might just need "2>/dev/null" at the end of the tar command to silence the errors.
If you want to test that, edit the command(s) in pkg-utils.inc and add it, and then:
Then reboot, that'll make it do the pkg reinstall when it boots back up.
Ermal has already committed a change to use mwexec() instead of plain exec() - that should stop the loads of console output. He also fixed up the %age display on the console so it doesn't keep spewing out all across the line. I'll give those a try.
ok, I've been a bit busy this morning so I didn't review the commit log yet.
I did a gitsync on my ALIX and ran the test I mentioned and it worked fine with the latest changes Ermal made, so this may be all solved now. (knock on wood)

Copy of console output is attached - cleaner than before. If I am feeling OCD I will find the appropriate places to put "\n" so that the %age output doesn't scribble over the beginning of a line of text.
Everything reinstalled fine - blinkled, openvpn, pfblocker, squid3
Note: squid3 left the mount ref count at 2 after its install. Thus the mount points do not go back to read-only. It has missing and mis-placed conf_mount_ro() calls. I have submitted a separate pull request to fix that. Not an issue for this thread.
Yep, I did feel OCD! I have put in a couple of pull requests to tidy up the console output some more. Everything functional seems fine. I'll see how the console output looks tomorrow after the next snapshot/upgrade/package install sequence.
After the conf_mount_ro fixups for squid and squid3 it should also leave the filesystem mounted read-only when finished.
