| 13:09.51 | stefan_schmidt | hi nh_work |
| 13:10.43 | nh_work | stefan: well, I got my E2 last night. Overall I'm fairly pleased with it, though they apparently have sent me a HK engineering sample. I'm not sure if that's a bad thing. |
| 13:12.14 | stefan_schmidt | nh_work: engineering samples are interesting if they deliver doc and schematic with it. :) |
| 13:14.12 | nh_work | stefan: yeah, I did a rudimentary exploration of the filesystem and it's still locked down with SELinux, though I can read many directories. Samba doesn't appear to be working. The etc conf files and init.d script is there, but the /usr/sbin is empty. |
| 13:14.18 | nh_work | so no daemon. |
| 13:14.56 | nh_work | telnet works fine though. the version file in /etc claims 33P firmware, but opera is claiming 32P. |
| 13:15.38 | stefan_schmidt | I still not get why they lock down some dirs but still allow telnet as root |
| 13:17.59 | nh_work | stefan: yeah, I'm not sure. I figure that the read access is there so that the phone can access various parts of the filesystem. Oh, I noticed that most of the EZX conf files were in /etc/ppp which just links /ram/tmp/ |
| 13:18.00 | florian_kc | stefan_schmidt: root is not really root with that selinux stuff |
| 13:18.42 | stefan_schmidt | florian_kc: Yes, but why not disable telnet at all? |
| 13:19.18 | florian_kc | stefan_schmidt: they did this on the a1200 firmware i have |
| 13:19.22 | nh_work | florian: do you know anything about the SELinux policy stuff? I need to start looking at the 33P source and see if we can find out how the policy on the phone is implemented. |
| 13:19.56 | stefan_schmidt | florian_kc: Ah, I was not aware of this. |
| 13:19.58 | florian_kc | nh_work: not much, of course it does not allow reading the policy file with that information in /etc |
| 13:21.17 | nh_work | florian: do they include any of that in the src package? |
| 13:22.38 | nh_work | I need to get/compile a vi binary for this thing too. |
| 13:24.40 | nh_work | hrm.... I wonder if I can use smbd from the a1200. |
| 13:24.54 | nh_work | too many things to try. |

| 13:25.51 | nh_work | stefan: oh, I noticed some x509 certs laying around on the phone too. |
| 13:26.37 | stefan_schmidt | nh_work: Perhaps, for moto websites. Or root CA's |
| 13:27.03 | nh_work | yeah, some root CAs, and some other stuff too, I didn't look too closely. |
| 13:32.17 | nh_work | oh, my 2GB sd card doesn't work in the phone. :( |
| 13:32.37 | nh_work | It detects it as unformated, and can't format it. :( |
| 13:33.33 | koen | one more reason to get 2.6 working |
| 13:33.51 | nh_work | definitely. |
| 13:36.58 | florian_kc | nh_work: i didn't find one so far, but i didn't search all that stuff |
| 13:37.56 | nh_work | florian: Ok. I might try to look at the src and see what I can figure out. |
| 13:39.59 | nh_work | I wonder if James Morris has done anything more with it. |

| 18:18.35 | proberts | What's locked on it? |
| 18:18.56 | nh_work | proberts: can't write to a lot of places, and I have a feeling a lot of files aren't visible even to root. |
| 18:19.11 | proberts | What firmware version does it have? |
| 18:19.29 | nh_work | it's that goofy motoAC SELinux fork that laf0rge was talking about. I can't find the src for it on opensource.motorola.com, but supposedly it is (or was) there. |
| 18:20.01 | nh_work | /etc/ap_version.txt claims R564_G_12.02.33P |
| 18:20.02 | proberts | I have it downloaded if they removed it... let me see if I can find where I got it from. |
| 18:20.08 | nh_work | opera was claiming 32P. |
| 18:22.05 | proberts | nh_work: Hmm... it looks like they have taken the source down, but they upped a new firmware version (12.03.33P). I have 12.02.33P-r2 from Nov 13th. Do you want a copy? |

| 18:39.13 | proberts | I just started reading about selinux a couple of days ago. I don't think having the policy will allow us to completely circumvent the security, but help to possibly create a work-around. |

| 19:04.04 | proberts | nh_work: later :) I got a shipping confirmation BTW so hopefully tomorrow or friday I'll have one and can help. |
| 19:04.48 | nh_work | proberts: good deal! :) My wife is probably going to end up hating this phone. ;) |
| 19:05.13 | proberts | nh_work: What phone does she use? |
| 19:05.43 | nh_work | proberts: oh, she uses an old nokia 3650. :) She won't hate it because of the phone itself, rather how much time I'm probably going to spend hacking away at it. :) |
| 19:06.53 | proberts | nh_work: ah... :P |
| 19:06.53 | nh_work | Still, it's the cellphone revolution. :) |
| 19:08.11 | proberts | True - Just tell her how much farther along you'll be when the carriers finally make the handset makers open up native APIs. |
| 19:08.42 | koen | you mean naive APIs |
| 19:09.06 | proberts | I sort of think of Java as a naive API ;) |

| 19:16.13 | nh_work | ac_policydb_read in acpolicy.c reads it. |
| 19:18.32 | proberts | do you have fs read access to it? |
| 19:18.37 | nh_work | yep |
| 19:18.56 | proberts | wow - that seems like a security hole :P |

| 19:25.25 | proberts | proberts9999@yahoo.com ... can you also include the .cfg file? |
| 19:26.16 | nh_work | proberts: I'm not sure if I should send the cfg file, I want to make sure this is by the book. |

| 19:32.38 | nh_work | supposedly... |
| 19:32.53 | proberts | is the fs mounted rw? |
| 19:33.31 | nh_work | hrm... /etc/fstab says ro, /etc/mtab says rw. :) |
| 19:34.17 | nh_work | some processes are running as root, some are running as ezx |
| 19:35.30 | proberts | can you 'su ezx'? |
| 19:36.02 | nh_work | naw, I thought of that earlier. No su. :) |
| 19:36.38 | _dion_3 | no su? strange |
| 19:36.44 | proberts | hmmm... what about newrole? |
| 19:37.31 | nh_work | Also, some files on the system are owned by 99:99 and 60001:97 |
| 19:38.42 | nh_work | no newrole that I can see. |
| 19:39.58 | proberts | ?? Doesn't kdevelop have a sourcecode call tree graph function? |
| 19:41.38 | nh_work | no idea... sounds like it would be useful if it did. :) |
| 19:42.00 | proberts | I thought I'd used it before, but I guess not (or I can't find it) |
| 19:42.37 | proberts | I can find where to do it from a compiled object, but not source. Odd. |
| 19:43.35 | nh_work | how do I upload a file to the wiki? |
| 19:44.25 | nh_work | oh, the toolbox |
| 19:54.08 | nh_work | hrm... I can't figure out how to make a new page. :) |

| 19:55.15 | _dion_ | nh_work: just go to non-existing page |
| 19:55.17 | stefan_schmidt | nh_work: Just type the url you like and you can edit it |
| 19:55.22 | nh_work | ah, ok |
| 19:55.51 | nh_work | it won't let me upload .txt files so I guess I just need to make new pages |
| 20:12.40 | proberts | nh_work: Are you on a x86 linux box? |
| 20:12.52 | nh_work | proberts: x86_64 |
| 20:13.24 | proberts | can you run m32 executables? |
| 20:13.56 | proberts | Does the cross compiler toolchain work with x86_64? |
| 20:15.03 | nh_work | proberts: I should be able to run m32 executables afaik... No idea on the second question, I haven't touched it yet. Honestly other than playing around with the hackndev palm linux stuff, this is my first foray into embedded linux. :) |
| 20:15.38 | koen | the hackndev stuff isn't a testament to 'good taste' and 'sane development practices' |
| 20:15.46 | nh_work | koen: tell me about it. |
| 20:16.01 | nh_work | koen: I can't believe it works. :) |
| 20:22.17 | proberts | nh_work: I have a stub app that I think will read and dump the policy file. Do you want me to send it to you, or do you want to send me the cfg to test it with? |
| 20:23.01 | nh_work | proberts: that was quick! :) |
| 20:23.32 | proberts | Well - I'm not 100% sure it will work as expected, since I haven't tried it :P |
| 20:25.31 | stefan_schmidt | proberts: I really appricate your efforts, but keep in mind sending stuff from the phone _can_ be illegal. |
| 20:25.33 | proberts | Want me to email it to you. |
| 20:25.58 | proberts | Ah - ok... so sending files from the phone is the issue. |
| 20:26.03 | nh_work | proberts: sure, send it to me. nels1678@umn.edu. |
| 20:26.40 | nh_work | I *think* it's probably ok as the file appears to be nothing more than a list of files which I believe can not be copyright, but I'm not totally sure. Hopefully you will get your phone soon. :) |
| 20:27.34 | proberts | Yeah - tomorrow or friday. |
| 20:27.54 | nh_work | proberts: still, this is great progress! |
| 20:28.11 | stefan_schmidt | proberts, nh_work: I'm not sure about exactly this file. And I know that it is more complicated this way. But it's the _right_ way. |
| 20:29.26 | proberts | stefan_schmidt: np |
| 20:29.37 | proberts | nh_work: email sent. |
| 20:31.36 | proberts | Yeah - I really think Motorola screwed up letting the comminuty define the API. They're going to learn the lesson the hard way like Sony did. |
| 20:32.04 | proberts | ...not that I'm sad about it... it's better for us! :) |
| 20:32.37 | nh_work | proberts: it worked, I'm replying back now with the output |
| 20:32.44 | proberts | cool! :) |
| 20:40.52 | proberts | Hmmm... interesting. |
| 20:40.53 | proberts | How do we find out what domain 'root' user is in? |
| 20:40.53 | nh_work | proberts: Not sure, but I imagine the SELinux guys or the source would know. ;) |
| 20:41.16 | proberts | You said there's no 'id' command, right? |
| 20:41.30 | nh_work | id works |
| 20:41.39 | proberts | oh - what output do you get? |
| 20:41.40 | nh_work | uid=0(root) gid=0(root) groups=0(root) |
| 20:44.28 | proberts | Hmmm... according to the selinux docs, selinux is supposed to dump security context info as well. hmmm.. |
| 20:47.21 | proberts | http://www.lurking-grue.org/selinuxHOWTO.html#gs2.2 <-- glossary for the dumped output |

| 21:01.59 | nh_work | stefan: ah |
| 21:03.32 | nh_work | stefan: can you take a look at the Rokr E2 page and tell me if you think everything there is fine? posting the result of strings on that file should be ok I think? |
| 21:05.20 | proberts | I think technically it's illegal for anyone in the US to try to reverse engineer or try to circumvent any sort of protection (no matter how lame) under the DCMA. You may want to obfuscate your name when you post (or have someone else post it for you) |
| 21:05.38 | *** join/#openezx |dion| (n=dionua@ns.inhex.net) |
| 21:07.43 | nh_work | proberts: Hrm... I wonder if this could be considered reverse engineering given that motorola released the source code to decipher the file under the GPL. |
| 21:07.51 | nh_work | And published it themselves. |
| 21:09.12 | proberts | I would think it might be questionable since the .cfg file was not released under the GPL. |
| 21:13.22 | stefan_schmidt | hmm, IANAL. No idea if the strings of a binary file are already re. |
| 21:14.12 | proberts | It looks trivial, if the .cfg file has +rw, to set our own policy. I don't see any cksum anywhere! :) |
| 21:14.51 | stefan_schmidt | I would vote for removeal, just to be safe. Even if it makes things a little bit harder. :( |
| 21:15.17 | proberts | If it is in violation of the DCMA, I guess it's not like Dick Cheney will shoot you in the face or anything. MOT would probably just ask that it be removed. They have bigger problems to worry about with their linux stuff. |
| 21:15.35 | stefan_schmidt | But if you keep going on so fast, we'll not have a selinux problem tommorrow anymore. ;) |
| 21:16.38 | proberts | stefan_schmidt: I think the issue is someone under US jurisdiction posting the info. If you or someone else on the list posts it, it's probably fine. |
| 21:16.38 | stefan_schmidt | proberts: Pehaps, but we like to have our website, wiki and code clean. |
| 21:17.11 | koen | find someone from Iran |
| 21:17.11 | nh_work | stefan: I could instead post a list of directories, and a list of files specified in the binary file. |
| 21:17.11 | nh_work | not the actual strings. |
| 21:17.11 | koen | Iran doesn't even acknowledge copyright :) |
| 21:17.25 | stefan_schmidt | proberts: But I don't have the phone... |
| 21:17.45 | stefan_schmidt | koen: People in Iran have perhaps other problems. |
| 21:18.22 | stefan_schmidt | nh_work: What's about posting a list with files and dirs you cannot access? |
| 21:18.40 | nh_work | stefan: well, some of them we don't know we can't access because we can't see them. :) |
| 21:19.44 | proberts | just AIR, the 'legality' isn't with posting the information, its in actually performing the act. nh_work and I may have already broken US law (probably have), but posting the info under a trackable name provides proof who did it. |
| 21:20.53 | nh_work | proberts: actually, I think it's really questionable if any law was broken given that you didn't actually read the file, you used motorola's publically available source code to read the file. |
| 21:22.18 | nh_work | you didn't really reverse engineer anything, you just read the file with the utilities they provided. |
| 21:22.41 | nh_work | well, you wrote a tool to call the utilities they provided, which I actually ran. ;) |
| 21:23.02 | koen | that's circumvention |
| 21:23.16 | koen | DMCA pwns y0u |
| 21:23.20 | proberts | nh_work: I don't think it matters if the code was legally available. Like DeCSS, the code was legally available. It's like the 'pig latin' example the EFF gave for the DCMA. If you wrote a document in pig latin and someone read it, they would be in violation of the DCMA. |
| 21:24.40 | proberts | nh_work: I'm not trying to discourage you from posting the info or anything though.. just concerned that it might come back to haunt you if they can track down who posted the info. |
| 21:25.11 | nh_work | proberts: Wouldn't all DVD players be illegal then though? |
| 21:25.35 | proberts | no, because DVD player makers pay a licensing fee to the owner of the CSS alg. |
| 21:26.05 | stefan_schmidt | hmm |
| 21:26.48 | proberts | For a while there were some Chinese DVD makers that weren't and (can't remember the company name) had their shipments impounded by customs. |
| 21:26.48 | stefan_schmidt | nh_work: Let the listing in the wiki for now if you like. |
| 21:27.12 | stefan_schmidt | nh_work: Perhaps I have to remove it later, not sure. |
| 21:27.43 | nh_work | stefan: Ok. What are you thinking? |
| 21:27.55 | proberts | all: I'm not trying to be a dick or anything... just an FYI. I'd say post it too... the most likely thing is nothing will happen.. probably worst case is Mot asks that it be removed. |
| 21:28.35 | nh_work | proberts: oh I know, it's good that you are bringing it up! |
| 21:29.00 | stefan_schmidt | proberts: I get you right. I like if people think about the problems they can have. |
| 21:29.22 | proberts | The only reason I was even thinking about it is I will probably have to hand off anything I do to someone else to post, since our company has a connection to Motrola and I don't want to screw that up. |
| 21:29.48 | stefan_schmidt | nh_work: At the moment I think "it's just listing of files. Damn, this should not be a problem." |
| 21:30.48 | proberts | If you want, you can post the .c file I sent with compile instructions as well. |
| 21:30.51 | nh_work | stefan: there are some other strings at the top besides files "file" "socket" "drm_rt" etc. |
| 21:32.21 | stefan_schmidt | nh_work: Anyway, let it there for now. |
| 21:32.43 | nh_work | ok |

| 21:35.27 | nh_work | yes |

| 21:35.46 | nh_work | I could copy them, let me try exe= |

| 21:36.08 | nh_work | Cannot find font definition file /usr/local/qt-embedded/lib/fonts/fontdir - is $QTDIR set correctly? |
| 21:36.34 | proberts | I think that made it past the security policy. |
| 21:36.42 | proberts | (unless it's a script) |
| 21:38.20 | proberts | hmmm... either I just don't get the selinux policy system (very possible) or it doesn't appear that root is restricted from anything. |
| 21:39.46 | nh_work | proberts: hrm... from what I can tell, the DMCA anti-circumvention clauses relate to circumventing copyright protection, but motorola is distributing the tools to circumvent it themselves. |
| 21:41.48 | proberts | That directory (/usr/SYSqtapp/phone/*) is marked as proctype 7, which has a domain type of 1, which is the carrier_domain. There are proctypes for "carrier, trusted, and untrusted", but they appear unused. |
| 21:42.45 | proberts | It doesn't look like root is restricted from anything??? |
| 21:43.42 | nh_work | well, for example I can't run mkdir in /usr/helix |
| 21:43.58 | proberts | what output do you get? |
| 21:44.18 | proberts | (and do you have +w premission) |
| 21:44.27 | nh_work | # mkdir test |
| 21:44.27 | nh_work | mkdir: cannot create directory `test': Operation not permitted |

| 21:46.14 | proberts | the policy for sid(1) on that directory is the same as the /usr/SYSqtapp/phone directory for sid(0) |
| 21:46.24 | proberts | can you chown it? |
| 21:48.00 | nh_work | proberts: I was able to chown a file in the directory, let me try the directory itself |
| 21:48.26 | nh_work | that worked |
| 21:48.52 | nh_work | still can't create a subdirectory even though root now owns it. |
| 21:50.27 | proberts | Ah - here's what I was thinking.. and I was wrong, you're safe to post it since you "legally obtained" the file: Notwithstanding the provisions of subsection (a)(1)(A), a person who has lawfully obtained the right to use a copy of a computer program may circumvent a technological measure that effectively controls access to a particular portion of that program for the sole purpose of identifying and analyzing those elements of the |
