| _ruben | rbasak: would you happen to have any clue as what could be the cause of bug #1008385, or in which direction to look? | 11:49 |
|---|---|---|
| uvirtbot | Launchpad bug 1008385 in apache2-mpm-itk "apache-mpm-itk writes wrong process name in /proc/$$/status" [Medium,Confirmed] https://launchpad.net/bugs/1008385 | 11:49 |
| _ruben | this bug report is pretty much the only info i could find on this matter | 11:50 |
| rbasak | _ruben: I'm not sure, sorry. I know that processes can modify their process name. Perhaps apache is doing it somewhere and getting it wrong for some reason? It's the sort of thing that probably needs a deep dive. | 11:52 |
| rbasak | And not being able to reliably reproduce it makes it difficult for anyone who isn't affected, of course. | 11:53 |
| _ruben | rbasak: that's about as much as i know as well ;) | 11:55 |
| _ruben | just ran a test on a bunch of servers i happened to be logged in on, at first sight more are affected than not | 11:56 |
| rbasak | _ruben: an explanation and patches will be greatfully accepted :) | 11:56 |
| rbasak | err, gratefully | 11:56 |
| rbasak | That word seems wrong to me this afternoon for some reason | 11:57 |
| _ruben | hehe | 11:57 |
| _ruben | wonder what will happen if i install -virtual kernel on a "broken" -generic vm .. will let you know in a bit ;) | 12:11 |
| rbasak | It might not be kernel related at all. | 12:32 |
| rbasak | That does seem less like to me, though I wouldn't rule it out. | 12:32 |
| _ruben | yeah .. finally managed to test booting -virtual .. no change | 12:37 |
| rbasak | Next I'd look for areas in the source that change the process name, and if there aren't any obvious bugs there, install debug symbols and get going with gdb. | 12:39 |
| rbasak | But there might be a better way of course | 12:39 |
| _ruben | i'll be *peeeep* .. i did a strace on a single worker (apache2 -X) .. no references to /usr/sbin/apach .. turns out: process name is ok | 12:48 |
| _ruben | rbasak: interesting ... apache2 -k start: OK .. apache2ctl start: FAIL | 12:49 |
| zul | roaksoax: ping | 12:54 |
| rbasak | strace is unlikely to catch it IMHO, if it's a problem with the process name being wrong. IIRC, changing process name doesn't involve a system call.l | 13:01 |
| rbasak | being set wrong, that is | 13:01 |
| _ruben | rbasak: the output of strace didn't help, but it did show me something else: apache2 (the binary) isn't responsible, not directly atleast | 13:05 |
| _ruben | disecting apache2ctl now | 13:05 |
| _ruben | (files are identical on both "kind" of servers unfortunately) | 13:05 |
| _ruben | the script is rather simple though | 13:06 |
| _ruben | ah! ... for some reason apache2 doesn't do proepr stipping for its process name | 13:07 |
| _ruben | apache2 -k start => apache2 ... /usr/sbin/apache2 -k start => /usr/sbin/apach | 13:07 |
| stgraber | rbasak: changing process name is done through the prctl syscall, so it should show up in strace | 13:10 |
| _ruben | stgraber: good to know | 13:10 |
| === Caine^^ is now known as C^^ | ||
| rbasak | stgraber: ah. I thought one could just change argv[0]? | 13:10 |
| _ruben | prctl(PR_SET_NAME, 0x7f0a15811b80, 0, 0, 0) = 0 | 13:11 |
| _ruben | I'm guessing 0x7... is a memory location | 13:11 |
| rbasak | _ruben: prctl(2) says that PR_SET_NAME is limited to 16 bytes, and should be null-terminated if shorter. "/usr/sbin/apach" is 15 bytes, and the 16th byte could be a null terminator. | 13:16 |
| rbasak | OTOH, "/usr/sbin/apache" is exactly 16 bytes, so does not need a null terminator. | 13:16 |
| rbasak | Perhaps there's a code path which limits the name to 15 bytes? | 13:16 |
| rbasak | (in order to account for the null terminator that isn't actually necessary)? | 13:17 |
| _ruben | it shouldnt be trying to set it to /usr/sbin/... in the first place | 13:18 |
| _ruben | the code doesn't call prctl directly though (not for this at least) | 13:18 |
| rbasak | http://web.archiveorange.com/archive/v/1XS1vcyaGboxxVcKF2sG | 13:20 |
| rbasak | Looks like prctl is limited to 16 characters, and overwriting argv still works but is limited to length of the original cmdline. | 13:20 |
| _ruben | process->argc = *argc; | 13:21 |
| _ruben | process->argv = *argv; | 13:21 |
| _ruben | process->short_name = apr_filepath_name_get((*argv)[0]); | 13:21 |
| _ruben | looks kinda promissing | 13:21 |
| rbasak | apr probably stands for Apache Portable Runtime. A portability abstraction, IIRC. | 13:22 |
| JanC | yes, some other applications use APR too | 13:23 |
| _ruben | but still .. all this doesn't explain how same package version on different systems could behave diffferently .. if it were "a simple" bug that is ;) | 13:24 |
| rbasak | _ruben: so it depends on how you start the service? I usually use "service apache2 start" rather than calling apachectl or apache2 directly. | 13:25 |
| _ruben | rbasak: any service wrapper is likely to use apache2ctl | 13:25 |
| rbasak | _ruben: how many reporters are doing something different that causes it to start differently? | 13:25 |
| rbasak | _ruben: the only wrapper I'm aware of is /etc/init.d/apache2. | 13:26 |
| _ruben | rbasak: none probably .. i know i aint | 13:26 |
| rbasak | Could there be two different code paths in the init script? | 13:27 |
| _ruben | my curent suspect: a envvar called APACHE_HTTPD .. apache2ctl initializes it to /usr/sbin/apache2, but if you override it to apache2, it works as expected .. let me check on a "good" server | 13:29 |
| JanC | so, maybe a default config differs between some older and current package versions? | 13:32 |
| rbasak | How about the upgrade path? Is everyone installing from fresh, or have they upgraded from a previous version? | 13:33 |
| JanC | rbasak: from the bug report it seems the working ones probably upgraded from 12.04.1, the broken ones installed 12.04.2 directly | 13:34 |
| _ruben | upgrade or fresh appears to be the very difference between good and bad | 13:34 |
| * rbasak looks up the diff | 13:36 | |
| _ruben | nope, the envvar isn't it .. changing that also changes the output in `top` .. `top` should list /usr/sbin/apache2 (that is, it does list it like that on both good and bad) | 13:36 |
| _ruben | which leads back to a bug in apache2's dirname stripping again .. which again would be rather unlikely | 13:37 |
| _ruben | i hate nasty bugs like this! :P | 13:37 |
| rbasak | I found them intruiging :) | 13:38 |
| _ruben | up to a point, sure ;) | 13:39 |
| rbasak | apachectl was modified in 2.2.22-1ubuntu1.3 though I can't immediately see that it caused this | 13:39 |
| rbasak | http://pastebin.ubuntu.com/5932802/ | 13:39 |
| _ruben | the change isnt in apache2ctl directly .. i compared those between a good and bad server | 13:39 |
| _ruben | i dont have any gdb skills .. or i'd trace the stuff upto the prctl call | 13:40 |
| _ruben | heck, even that apr_ function goes beyond my C knowledge, and its pretty simple function | 13:41 |
| roaksoax | zul pong | 13:43 |
| rbasak | I don't see anything else relevant in the update diffs | 13:44 |
| zul | roaksoax: available to do some reviews today? | 13:44 |
| rbasak | Most of the udpates have been in moduels | 13:44 |
| _ruben | wonder if it's some obscure libc related thing or something | 13:45 |
| roaksoax | zul nah :p | 13:45 |
| zul | roaksoax: ok then | 13:46 |
| roaksoax | zul lol i am | 13:46 |
| rbasak | _ruben: but why would it be random? Or if it is only affecting upgraded systems, what is different about them to cause that to happen? | 13:48 |
| rbasak | _ruben: anything different in /etc/default/* or /etc/apache2/* between the two systems? | 13:48 |
| roaksoax | zul just send them my way and ill review them as soon as my network behaves right | 13:50 |
| zul | roaksoax: ack | 13:50 |
| _ruben | rbasak: i dont think its random, just a change that only affects new installs, and not upgrades .. as for changes in those locations: haven't found anything obvious, yet | 13:58 |

| chmac | I've got a machine on which mysql / apache do not start at boot. The /etc/init/mysql.conf contains a 'start on runlevel [2345]' line. How else can I debug the issue? | 16:06 |
| ikonia | chmac: try to start them manually - confirm there is no problem | 16:07 |
| chmac | ikonia: Yeah, they both start ok | 16:07 |
| ikonia | that seems odd then | 16:07 |
| ikonia | chmac: maybe worth putting a touch /tmp/testfile.mysql(or apache) at the start of the script and see if the scripts even get executed | 16:08 |
| chmac | ikonia: Ok, interesting, to see if maybe upstart is not getting started or something. | 16:08 |
| chmac | I'm a little out of my depth on this stuff. Thankfully ssh does start! | 16:09 |
| ikonia | chmac: yes, simple test to see if the scripts even get excuted or not | 16:09 |
| ikonia | chmac: then you know the problem is not the scripts, but that they aren't getting run | 16:09 |
| ikonia | chmac: or you know there is a problem with the scripts and you can take it from there | 16:09 |
| chmac | ikonia: The scripts are the stock, whatever was installed with the system | 16:10 |
| chmac | ikonia: I'll try that now and reboot. Thanks for the suggestion. | 16:10 |

| Peryton272 | I'm having a problem installing Ubuntu Server to my Dell PowerEdge 2600. Is this the right place to be? | 19:02 |
| sarnold | Peryton272: sure | 19:04 |
| Peryton272 | so I boot from the disk that has the .iso on it, but when it boots my server no longer recognizes my USB keyboard so I cant even select a language or anything. | 19:04 |
| Peryton272 | the keyboard works fine in the Dell bios but as soon as I try to boot from the disk that has Ubuntu on it, the keyboard stops working | 19:08 |
| sarnold | Peryton272: some BIOSes have a setting for how to handle usb keyboards and mice; it's intended to help along OSes without USB support, like many win95, win2k releases, but if you fiddle with it, you might get lucky? | 19:09 |
| Peryton272 | alright I'll see if I can find something | 19:09 |
| Peryton272 | sarnold: I got it to work. Thank you! | 19:17 |
| sarnold | Peryton272: cool, what was it? | 19:21 |
| Peryton272 | just what you said. I had to turn on the bios support for USB devices | 19:21 |
| sarnold | Peryton272: crazy. that shouldn't have been needed since 2.0 or 2.2 kernels, I forget which it's been long enough... anyway. hooray. :) | 19:22 |
| Peryton272 | sarnold: now it's saying "This kernel requires an x86-64 CPU, but only detected an i686 CPU." | 19:26 |
| Peryton272 | sarnold: What does that mean? lol I haven't done anything with servers before | 19:27 |
| sarnold | Peryton272: there's two images for x86 systems, i386 and amd64. the amd64 ones will require the x86-64 CPUs, but it sounds like you've got a machine that'll require the i386 image instead | 19:27 |
| Peryton272 | sarnold: oh ok. Could you point me in the right direction to get that? | 19:29 |
| sarnold | Peryton272: http://www.ubuntu.com/download/server note the 'choose your flavour' drop down, you'll want the 32 bit option | 19:30 |

| joshu | ok going to test | 22:55 |
| sarnold | joshu: note that you don't have to reboot to test that -- you can just service brscan-skey-daemon restart | 22:57 |
| joshu | sarnold oh ok tried with chdir but it is still writing to /brscan | 22:59 |
| sarnold | joshu: what's the home directory for the test user? | 22:59 |
| joshu | "/home/test/brscan" | 23:00 |
| joshu | I tried chdir /home/test/brscan | 23:00 |
| sarnold | joshu: try just chdir /home/test, and try changing the home directory in /etc/passwd to just /home/test as well | 23:01 |
| joshu | ok let me try one sec | 23:03 |
| joshu | still same thing | 23:03 |
| joshu | tiff2pdf: Can't open output file /brscan/20130801010332_27436.pdf for writing. | 23:04 |
| joshu | I don't know what su -c does instead of setuid that the former works | 23:04 |
| sarnold | joshu: hrm, me neither. you could go back to su -c .. | 23:06 |
| joshu | ok is the script otherwise written ok? something I found odd is that if i kill the process using sudo kill <number> and then do sudo status brscan…. the process number is the same. Doesn't seem right to be if it respawns? | 23:07 |
