| 17:48.02 | Dr{Who} | having some problems booting on a via epia 5000 board. My setup works fine on qemu or an intel board. Kernel starts loading the init but it is as if the init process never starts. I have a simple "hello world" init binary staticly compiled to try and debug this. On the intel box or qemu it works fine i see it load the elf binary on my via board as its loading the binary it segfaults during the memory copy and i get a strange event sent to |
| 17:48.02 | Dr{Who} | the thread. I end up seeing a do_notify_resume with 0x04 or TIF_SIGPENDING.. then it just keeps doing this over and over |
| 17:48.25 | Dr{Who} | need ideas how to continue to debug this |
| 17:49.15 | Dr{Who} | 2.6.22.10 kernel btw. i have patched in kdb to help debug |
| 17:53.21 | Dr{Who} | i also noticed that during the copy of the elf bin into user memry a clear_user is called on both boxes a page_fault is issued im presuming for dynamic memory allocation. But in the intel vs via the signal's re different. intel has a sighand_ctor where the via just goes direclty to error_code |

| 18:21.08 | sstallion | morning guys |
| 18:21.19 | sstallion | morning guys... do any of you know if a openssl compatible micro-lib exists out there? |
| 18:22.43 | Dr{Who} | my buildroot tree has a make setup for openssl |
| 18:23.04 | Dr{Who} | and i have no problems compiling it |
| 18:23.42 | sstallion | well, i ended up not being able to use buildroot on this project :/ |
| 18:23.45 | sstallion | (unfortunately) |
| 18:24.07 | Dr{Who} | well the make directory should give you any help you may need though |
| 18:24.14 | Dr{Who} | let me look at mine see if they do anything special |
| 18:24.47 | sstallion | thanks a bunch |
| 18:25.21 | Dr{Who} | ya a few patches in there |
| 18:25.29 | Dr{Who} | looks like they patch the configure |
| 18:26.19 | Dr{Who} | and the patch out building of the docs |
| 18:26.36 | Dr{Who} | maybe if you just used the patches and then cross compile should work |
| 18:26.56 | *** join/#elinux __fonz__ (n=tp@e178033238.adsl.alicedsl.de) |
| 18:28.11 | Dr{Who} | looks like the main patch has lots of stuff for different processors and asmembly/compiler changes |
| 18:33.09 | sstallion | hrm ill give that a shot |
| 18:33.12 | sstallion | thanks again |
| 18:34.54 | Dr{Who} | also look at this http://landley.net/code/firmware/about.html |
| 18:35.10 | Dr{Who} | landley is on #uclibc he may have some ideas on openssl |
| 18:35.43 | Dr{Who} | i have not used his build system i use buildroot but it looks solid.. |
| 18:39.05 | sstallion | hrmm i'll do that |
| 18:39.40 | sstallion | we have a custom toolchain here so its a little tough to use buildroot or other scripts :/ |
| 18:40.03 | Dr{Who} | ya.. well try that patch or at least parts of it |
| 18:40.15 | Dr{Who} | most look ok some parts are just changing path's etc |
| 18:40.17 | sstallion | will do - i have a compile rolling on it now |
| 18:40.19 | sstallion | yeah |
| 18:40.23 | Dr{Who} | then build with that and see what breaks : c 0 |
| 18:40.43 | sstallion | hrmm built clean |
| 18:40.50 | Dr{Who} | yay. |
| 18:40.55 | Dr{Who} | : c ) now does it work.......... |
| 18:41.01 | sstallion | tests blew out... dammnit |
| 18:41.24 | sstallion | the ironic thing is that libssl is only a compile time req' its not actually used on the target |
| 18:41.28 | Dr{Who} | as in openssl tests? or some of your own tests? |
| 18:41.33 | sstallion | openssl tests |
| 18:41.37 | Dr{Who} | ahh. |
| 18:41.51 | Dr{Who} | well i dont know.. that may be tough. the openssl tests may also need fixing. |
| 18:41.57 | sstallion | *nod* |
| 18:42.35 | Dr{Who} | does your configure have an option to remove that dependancy? |
| 18:42.44 | sstallion | looks like it |
| 18:43.04 | Dr{Who} | ya like --nossl or something |
| 18:43.33 | sstallion | oh, you mean on the dependant software? no |
| 18:43.46 | sstallion | its a hard dep |
| 18:43.47 | Dr{Who} | ah. |
| 18:43.52 | sstallion | (bastards) |
| 18:44.10 | Dr{Who} | so this software at what point does it break? |
| 18:44.15 | Dr{Who} | during configure? or make? |
| 18:44.26 | sstallion | its fully make driven, so during make |
| 18:44.40 | Dr{Who} | and the error? |
| 18:44.57 | sstallion | basically that it depends on openssl (ie: cant find headers, cant link to libssl etc.) |
| 18:44.59 | Dr{Who} | i would say you can just modify the make to remove the -l for ssl |
| 18:45.26 | Dr{Who} | well #includes you would have to remove manualy if it truely does not need them |
| 18:45.28 | sstallion | true... i could just remove ssl support |
| 18:45.34 | Dr{Who} | and the libssl you can remove just modify the link options. |
| 18:45.36 | sstallion | easy enough to add a NO_SSL macro |
| 18:45.46 | Dr{Who} | yep. |
| 18:46.15 | sstallion | hrmm maybe 50 source files... that may end up being easier |
| 18:46.27 | sstallion | seems a shame to trash a nice lean busybox build with openssl ;) |
| 18:46.34 | Dr{Who} | heh |
| 18:46.47 | Dr{Who} | so back to the openssl build itself |
| 18:46.50 | Dr{Who} | it did compile right? |
| 18:47.10 | sstallion | it did, but not using a true cross-compile |
| 18:47.15 | Dr{Who} | ahh |
| 18:47.24 | Dr{Who} | ya need to be cross compied |
| 18:47.26 | sstallion | the target is a i386 (im on an x64) - so it doesnt really count ;) |
| 18:47.28 | Dr{Who} | or it wont like correctly. |
| 18:47.31 | sstallion | *nod* |
| 18:47.38 | Dr{Who} | its uclibc right? |
| 18:47.48 | sstallion | yup |
| 18:47.52 | sstallion | i386-linux-uclibc |
| 18:48.10 | Dr{Who} | ya so you have to build it against uclibc also then it will link correctly with your project |
| 18:48.16 | sstallion | *nod* |
| 18:48.23 | sstallion | i might look into disabling ssl altogether |
| 18:48.27 | sstallion | its not needed for this prototype |
| 18:48.42 | sstallion | i think it may just be an addon to the protocol were working with |
| 18:49.00 | *** join/#elinux thraxisp (n=thraxisp@24.139.16.154) |
| 18:49.10 | Dr{Who} | ya probably. an option to talk ssl or clear text via tcp is common. |
| 18:49.22 | sstallion | ahh interesting... its wanting to use lcrypt |
| 18:49.38 | sstallion | this might be easier to replace just by providing an alternate libcrypt and swapping out some headers |
| 18:50.16 | Dr{Who} | well libcrypt is for basic encryption math md5's etc etc |
| 18:50.19 | sstallion | does uclibc provide a libcrpt? |
| 18:50.21 | sstallion | right |
| 18:50.28 | Dr{Who} | let me see |
| 18:50.32 | sstallion | theyre relying on md5 and sha1 sums |
| 18:50.41 | sstallion | (just using openssl's version of it) |
| 18:50.46 | Dr{Who} | ahh |
| 18:50.55 | Dr{Who} | ok well that is easier to remove the dependancy then |
| 18:51.01 | sstallion | yup |
| 18:52.02 | Dr{Who} | libgcrypt |
| 18:52.15 | Dr{Who} | its an option on uclibc |
| 18:52.32 | sstallion | looking in there now |
| 18:53.23 | sstallion | any idea of what the option is named? |
| 18:54.05 | Dr{Who} | sorry i ment that is for buidroot my bad |
| 18:54.11 | sstallion | ah |
| 18:54.13 | Dr{Who} | uclibc is just libc |
| 18:54.21 | Dr{Who} | i dont think they have anything else. |
| 18:54.28 | sstallion | well they add in a couple of extras... pthreads etc. |
| 18:54.37 | Dr{Who} | ok true that. |
| 18:54.38 | sstallion | although i guess technically you could call that part of libc |
| 18:55.10 | sstallion | hrmm |
| 18:55.18 | Dr{Who} | you know its not hard to make a .mk pacakge of your own for buildroot |
| 18:55.52 | sstallion | i think the part that dissapointed on buildroot for this project was the number of artifacts the owner considered unneccessary |
| 18:56.04 | Dr{Who} | then you can just grab the libs and bins you need and deploy it as you wish. |
| 18:58.18 | Dr{Who} | for example if i want to build something for my mips based tivo box i would use buildroot just to get a cross compiler and the libs i want then i can compile static if needed to and wala i have a bin for my tivo box. |
| 18:58.35 | sstallion | true |
| 18:59.01 | sstallion | hrmm looks like only one bit of source uses openssl for md5 and sha1 |
| 18:59.11 | Dr{Who} | for that matter you can add --static and build your bin directly to x86 |
| 18:59.14 | sstallion | i think it will be better just to find an alternate version of lcrypt |
| 18:59.23 | sstallion | *nod* |
| 18:59.27 | Dr{Who} | directly from any buildtree |
| 18:59.48 | Dr{Who} | it will be big but as you said its a prototype : c ) |
| 19:00.19 | Dr{Who} | the only bugger wil be if your app dynamicly loads lib's i have never gotten that to work.. |
| 19:00.30 | Dr{Who} | like if it has modules.. it loads. |
| 19:00.36 | sstallion | ahh |
| 19:00.40 | sstallion | i dont think so... not with this |
| 19:00.55 | Dr{Who} | well then just add --static to your make and it should run on your box |
| 19:00.57 | sstallion | i just spent a week squashing all static bin's though ;) |
| 19:00.59 | Dr{Who} | regardless of lib's |
| 19:01.15 | Dr{Who} | heh |
| 19:01.27 | Dr{Who} | 2 steps forward 1 back. |
| 19:01.33 | Dr{Who} | tis the name of the game |
| 19:01.42 | sstallion | amen to that |
| 19:02.04 | sstallion | still, adding in openssl for f'n md5 is terrible - i cant believe these guys did that |
| 19:03.16 | sstallion | interesting |
| 19:03.23 | Dr{Who} | so maybe just switch out the functions with libcrypt |
| 19:03.23 | sstallion | uclibc *does* have libcrypt |
| 19:03.28 | Dr{Who} | realy? |
| 19:03.32 | sstallion | yup |
| 19:03.36 | sstallion | http://www.uclibc.org/cgi-bin/viewcvs.cgi/trunk/uClibc/libcrypt/ |
| 19:04.08 | sstallion | i'll be damned |
| 19:04.13 | sstallion | its built |
| 19:04.19 | sstallion | so this should be a quick fix |
| 19:04.26 | Dr{Who} | wow there ya go. |
| 19:05.12 | sstallion | just need to convert to crypt.h |
| 19:06.29 | sstallion | crap |
| 19:07.17 | sstallion | theyre not using the crypt functs... theyre using openssl specific ones |
| 19:07.51 | Dr{Who} | well i would think they are simmilar so patching in calls to libcrypt vs openssl is probably not a huge diff |
| 19:08.02 | sstallion | theyre pretty close |
| 19:08.04 | Dr{Who} | openssl lib is easy to use used it many times. |
| 19:08.52 | Dr{Who} | just dont need to init the lib and load your modules you would just call directly the crypt functions |
| 19:09.36 | sstallion | i might have to convert all of this into a crypt() call instead of the md5 primitives |
