| KotCzarny | i wonder why /etc/fstab is dynamically created on every boot | 10:21 |
| *** geaaru has joined #maemo | 10:39 | |
| * Maxdamantus doesn't really like the idea of defining core filesystem layout with /etc/fstab | 10:41 | |
| Maxdamantus | imo it should be there to make mounting things slightly easier for the user. | 10:41 |
| KotCzarny | um, *nix wasnt for users | 10:42 |
| KotCzarny | it was server os, and admin had the right for defining what mounts | 10:42 |
| Maxdamantus | eg, /boot isn't usually necessary, so put it in /etc/fstab so you can `mount /boot` when you do need it. | 10:42 |
| Maxdamantus | server? You mean time sharing? | 10:42 |
| KotCzarny | you can always define user mountable things with udev scripts | 10:43 |
| Maxdamantus | They didn't have servers and clients in the beginning. They just had a machine with a bunch of terminals attached. | 10:43 |
| KotCzarny | yes, and users didnt mount anything | 10:43 |
| Maxdamantus | (and the people on those terminals certainly used the OS) | 10:43 |
| kerio | i have a static fstab | 10:43 |
| kerio | because of reasons | 10:43 |
| Maxdamantus | It was designed to be usable. | 10:43 |
| Maxdamantus | in an era when "usable" meant using text editors like `ed` | 10:44 |
| KotCzarny | users are stupid, ie, they usually physically disconnect things without umounting | 10:45 |
| KotCzarny | and you either have to decide if you want performance or usability | 10:45 |
| Maxdamantus | It's stupid that filesystems still can't handle that. | 10:45 |
| KotCzarny | no device can handle powerloss in the middle of the write | 10:46 |
| Maxdamantus | .. yes, plenty of devices can. | 10:46 |
| KotCzarny | user class? | 10:46 |
| Maxdamantus | It's a limitation of the organisation of filesystems and software that means you should unmount things before removing them, not really hardware. | 10:47 |
| Maxdamantus | Removable devices often have a light that flashes during activity. | 10:48 |
| kerio | yeah we could just mount things without any cache | 10:48 |
| Maxdamantus | Theoretically, you should be able to just wait until it stops flashing; that should indicate that your transfers are done. | 10:48 |
| kerio | and lose ANY performance | 10:48 |
| KotCzarny | maxd, what about delayed writes | 10:48 |
| KotCzarny | user starts ejecting drive when os decides to flush buffers | 10:49 |
| kerio | KotCzarny: in Maxdamantus' world we have to mount things with sync,data=ordered | 10:49 |
| kerio | and open all files with O_DIRECT | 10:49 |
| Maxdamantus | kerio: no. Journalling is stupid. | 10:49 |
| kerio | haahhhahahahahahaha | 10:49 |
| KotCzarny | lol | 10:49 |
| kerio | HAHAHAHAHAHAHHAh | 10:49 |
| kerio | HAHAJJAHSFJAHSJFHAJSFHAJSF | 10:49 |
| Maxdamantus | kerio: the main filesystem on your phone doesn't journal. | 10:49 |
| kerio | ok you're definetely a troll | 10:49 |
| *** vectis has quit IRC | 10:49 | |
| kerio | the main filesystem on my phone is ubifs | 10:50 |
| kerio | which is journaled | 10:50 |
| Maxdamantus | kerio: ubifs is fairly resiliant to power loss without journalling, because it was designed after everyone knew that journalling was a stupid way of solving that issue. | 10:50 |
| kerio | the other filesystem is ext4 | 10:50 |
| kerio | which is journaled | 10:50 |
| kerio | dude | 10:50 |
| KotCzarny | it's all about deciding how much performance/stability/usability to have | 10:50 |
| kerio | are you serious | 10:50 |
| kerio | ubifs is journaled | 10:50 |
| Maxdamantus | kerio: yes, I'm totally serious. | 10:50 |
| Maxdamantus | kerio: it's a log-based filesystem, not a journalled filesystem. | 10:50 |
| Maxdamantus | kerio: you can look this shit up. | 10:50 |
| kerio | UBIFS automatically replays its journal and recovers from crashes, ensuring that the on-flash data | 10:50 |
| kerio | structures are consistent. | 10:50 |
| kerio | ubifs is not a log-structured filesystem | 10:50 |
| Maxdamantus | Oh, okay, it's journalled. That's silly. | 10:52 |
| KotCzarny | :) | 10:52 |
| kerio | :) | 10:52 |
| Maxdamantus | Well, actually, it depends how it's implemented. | 10:52 |
| Maxdamantus | I suspect it's quite different to the "journalling" done by ext. | 10:53 |
| Maxdamantus | Since it works on top of MTD, so it should naturally be avoiding writing over things. | 10:54 |
| Maxdamantus | otherwise writes to the same file would keep writing to the same block (unless you're relying on a fancy FTL under your filesystem), which is bad. | 10:54 |
| KotCzarny | is emmc wear levelled? | 10:54 |
| Maxdamantus | Of course. It has a controller inside that manages that. | 10:55 |
| KotCzarny | i'm planning to move whole os to emmc or sd | 10:55 |
| Maxdamantus | http://lxr.free-electrons.com/source/fs/ubifs/journal.c#L26 | 10:56 |
| Maxdamantus | No copying. | 10:57 |
| Maxdamantus | unlike ext (where you need to specify ordered writes or full data journalling (writing twice) to provide the sort of guarantees that should be implicit) | 10:58 |
| Maxdamantus | also, 19:50:07 < kerio> the other filesystem is ext4 | 10:59 |
| KotCzarny | no stable ext4 for 2.6.28 | 10:59 |
| Maxdamantus | Theodor Ts'o (the maintainer of ext4) has said that filesystems should be moving towards something like btrfs rather than ext4. | 11:00 |
| KotCzarny | nor btrfs | 11:00 |
| KotCzarny | which is why having 4.x in fremantle would be awesome | 11:00 |
| KotCzarny | or in n900 os in general | 11:01 |
| KotCzarny | standard fremantle (without *.avi and *.mp3) is ~ 138M for rootfs, ~190M for home/opt and ~33M for mydocs | 11:03 |
| Maxdamantus | 2.9G /btrfs/bk/n900/homefs/150906.mnt/select/maemo5-root | 11:04 |
| KotCzarny | :) | 11:04 |
| KotCzarny | some chroot? | 11:04 |
| Maxdamantus | Yes. | 11:04 |
| * Maxdamantus just uses the ubifs as a portable initramfs. | 11:07 | |
| Maxdamantus | er, mutable* | 11:07 |

| Maxdamantus | Memory? | 11:08 |
| KotCzarny | having initramfs | 11:08 |
| KotCzarny | unless you free it after boot | 11:09 |
| Maxdamantus | It's not an actual initramfs, but no, that wouldn't necessary eat memory. | 11:09 |
| Maxdamantus | or just remove the files. | 11:09 |
| KotCzarny | that's what i meant | 11:09 |
| * Maxdamantus currently has his laptop set up to use an actual initramfs as his root. | 11:10 | |
| KotCzarny | let's stick to n900 as a subject | 11:10 |
| KotCzarny | pc can have gigs of mem | 11:10 |
| Maxdamantus | I think you can unmount the initramfs after doing a pivot_root. | 11:11 |
| KotCzarny | or just remove the files, as you've said | 11:11 |
| KotCzarny | still, some will remain mapped by init and things you ran before pivot | 11:11 |
| Maxdamantus | You shouldn't run init before pivoting. | 11:12 |
| KotCzarny | it won't be pid 1 then | 11:12 |
| Maxdamantus | Sure it will. | 11:13 |
| Maxdamantus | Don't fork, just exec. | 11:13 |

| KotCzarny | maxd: what's that? | 11:30 |
| Maxdamantus | x is number of minutes into the day, y is mV of battery according to bq272.. | 11:31 |
| KotCzarny | you know that sampling it so often will drain the battery? | 11:31 |
| KotCzarny | also, same data you could get using battery-eye or similar | 11:32 |
| Maxdamantus | I can't imagine it being that significant. | 11:32 |
| Maxdamantus | It's every 5 seconds. | 11:32 |
| KotCzarny | uhuhu, often | 11:32 |
| Maxdamantus | and it's going through the kernel module, dunno when that looks at the registers. | 11:32 |
| KotCzarny | switch to 60s and compare | 11:33 |
| Maxdamantus | otherwise it's just a small amount of processing every 5 seconds and writing a bit to the eMMC. | 11:33 |
| Maxdamantus | it's computationally more efficient than doc's normal script. | 11:33 |
| Maxdamantus | though yes, still not optimal .. that probably wouldn't invoke something like sed. | 11:34 |
| KotCzarny | nope, that would involve c | 11:34 |
| KotCzarny | shell scripts are easy to write but are heavy on resources (compared to c) | 11:35 |
| Maxdamantus | It's still fairly insignificant in this case. | 11:35 |
| KotCzarny | still, for a quickie change 5s into 60s and compare | 11:36 |
| Maxdamantus | It's basically just invoking a sed process every 5 seconds. | 11:36 |
| Maxdamantus | Everything else is in the shell. | 11:36 |
| Maxdamantus | (the normal script invokes i2c lots of times) | 11:36 |
| KotCzarny | if there is noticeable difference you will know its draining | 11:36 |
| Maxdamantus | real 0m17.231s | 11:38 |

| Maxdamantus | dunno what clock speed. | 11:38 |
| Maxdamantus | probably 200 MHz | 11:39 |
| KotCzarny | any % cpu > idle/sleeping cpu | 11:39 |
| KotCzarny | and 0.5s every 5s? | 11:39 |

| KotCzarny | FATAL: Error inserting g_ether (/lib/modules/2.6.28.10-power53/g_ether.ko): Device or resource busy | 12:37 |
| KotCzarny | bme is blocking usb networking? | 12:37 |
| Maxdamantus | You need to remove any other g_ modules. | 12:37 |
| Maxdamantus | like g_nokia or g_file_storage | 12:37 |
| KotCzarny | uhum | 12:37 |
| KotCzarny | thx, worked | 12:38 |
| Maxdamantus | I don't think bme is able to block the kernel loading modules. | 12:38 |
| KotCzarny | it g_file_storage was loaded even if device was in 'charging only' state | 12:38 |
| Wizzup | it does that, yes | 12:38 |
| Maxdamantus | Yeah, I never understood that dialogue. | 12:39 |
| Wizzup | but it just exports an empty block device then iirc | 12:39 |
| KotCzarny | it should be considered a bug | 12:39 |
| * Maxdamantus wants to remove that. | 12:39 | |
| * Maxdamantus thinks he remembers tracing it down to something in ke-recv. | 12:39 | |
| Maxdamantus | Annoying having the screen activate just because you plug it in to charge. | 12:40 |
| KotCzarny | yeah, it should be done as status bar applet | 12:40 |
| KotCzarny | with last-mode remembered | 12:40 |
| * Maxdamantus loads g_ether in rcS-late, so ke-recv or whatever fails to load g_file_storage or whatever. | 12:41 | |
| KotCzarny | echo "$DESC: USB networking enabled, ignoring USB cable" | 12:41 |
| KotCzarny | export OSSO_KE_RECV_IGNORE_CABLE=1 | 12:41 |
| KotCzarny | i think you can play with that | 12:42 |
| Maxdamantus | Hm. | 12:42 |
| KotCzarny | /etc/init.d/ke-recv | 12:42 |
| Maxdamantus | I think I already have that. | 12:43 |
| Maxdamantus | it still wakes the screen up and shows the dialogue. | 12:43 |
| KotCzarny | i mean, to control whatever runs from hal | 12:43 |
| KotCzarny | thx for the ke-recv pointer, will hunt it later | 12:44 |
| Maxdamantus | I think I might've just stopped running ke-recv at some point, but I think that prevented the camera application from working. | 12:45 |
| Maxdamantus | can't remember. | 12:45 |
| Maxdamantus | It seems like the sort of stuff I don't want anyway. | 12:46 |
| KotCzarny | can you still set usb mode? | 12:49 |
| KotCzarny | (without cmdline) | 12:49 |
| Maxdamantus | Dunno. I've always done that using a command line. | 12:50 |
| KotCzarny | ie. if you plug usb, do you have a usb button in status bar? | 12:50 |
| Maxdamantus | Without ke-recv? Can't remember. | 12:50 |
| Wizzup | 11:40 < KotCzarny> with last-mode remembered | 12:52 |
| Wizzup | really? ;) | 12:52 |
| *** ssvb has joined #maemo | 12:52 | |
| KotCzarny | wizzup, well, would work for 'charing only' for me | 12:52 |
| KotCzarny | :) | 12:52 |
| Wizzup | sure. | 12:52 |
| KotCzarny | and enabling g_ether at all times | 12:52 |
| Wizzup | Not when it remembers g_file_storage | 12:53 |
| Wizzup | (that would be annoying) | 12:53 |
| KotCzarny | right now it behaves like broken g_file_storage | 12:53 |
| Wizzup | KotCzarny: wrt usb mode, there's a very nice applet to do it | 12:53 |
| KotCzarny | ie. module loaded, but no driver mountable | 12:53 |
| Maxdamantus | Damn it, VDQ disappeared. | 12:53 |
| KotCzarny | vdq not importants, ci importants | 12:53 |
| Maxdamantus | VDQ important if you're trying to calibrate to a new battery. | 12:54 |
| KotCzarny | unless you are in the middle of calibration | 12:54 |
| KotCzarny | wizzup: name? | 12:54 |
| Maxdamantus | it went off an hour and fifteen minutes ago. | 12:54 |
| KotCzarny | maxd: maybe you've connected usb or something | 12:55 |
| Maxdamantus | I haven't connected USB. | 12:55 |
| Wizzup | KotCzarny: sorry, for host mode or swithing g_applets | 12:55 |
| KotCzarny | nah, no need for host mode (atm) | 12:55 |
| KotCzarny | but i would like usb charing/storage/pcsuite mode switchable without reconnecting the cable | 12:56 |
| KotCzarny | (via applet button) | 12:56 |
| Maxdamantus | it's been saying 6% charge for four hours. | 12:56 |
| Maxdamantus | and is still at 3.7 V | 12:56 |
| Wizzup | KotCzarny: right, no, the applet only allows switching initially | 12:56 |
| Maxdamantus | (it doesn't go lower than 6%) | 12:56 |
| KotCzarny | maxd: some weird battery stup? | 12:56 |
| Wizzup | but it doesn't allow switching from say 'pc suite mode' to 'none' | 12:56 |
| Wizzup | so then you need to use cmdline | 12:56 |
| Maxdamantus | No, bq just doesn't seem to go lower than 6% | 12:56 |
| KotCzarny | wizzup, seems like trivial thing to write | 12:56 |
| KotCzarny | TODOed | 12:57 |
| Maxdamantus | so supposedly my other battery would've run out four hours ago. | 12:57 |
| KotCzarny | maxd: there was some nice guide for calibrating baterries with very big differences since the last one used | 12:57 |
| KotCzarny | *batteries | 12:58 |
| Maxdamantus | Maybe the trick is to just use the power quickly. | 13:03 |
| Maxdamantus | Oh, interesting. It actually does go below 6% | 13:04 |
| Maxdamantus | after VDQ = 0 | 13:04 |
| Maxdamantus | while VDQ = 1, it was just sitting at 6% for hours. | 13:05 |
| Maxdamantus | The earphones I should be getting in a couple of days have an angled connector, which should be relatively convenient for the N900. | 13:41 |
| KotCzarny | hmm | 13:49 |
| KotCzarny | one nice thing about using g_ether and not g_mass_storage will be easy file sharing | 13:49 |
| KotCzarny | and it will no longer require mounting/umounting at the n900's side | 13:49 |

| KotCzarny | http://members.inode.at/anton.zechner/az/AzSmb.en.htm | 13:58 |
| KotCzarny | The program code needs 250 kByte. | 13:58 |
| KotCzarny | sounds doable | 13:58 |
| KotCzarny | let's see if it compiles | 13:58 |
| ceene | is thumb the same as thumb2? | 14:10 |
| KotCzarny | ~thumb | 14:10 |
| infobot | extra, extra, read all about it, cssu-thumb is <Doc_Scrutinizer05> [thumb2 microb] indeed seems to render like mad, subjectively, or http://talk.maemo.org/showpost.php?p=1220597, or http://wiki.maemo.org/Community_SSU/Thumb | 14:10 |
| KotCzarny | see the links | 14:10 |
| KotCzarny | but yes, compile wise using -thumb enables thumb2 | 14:10 |
| ceene | that was the doubt, thanks | 14:11 |
| ceene | ours is a Cortex-A8? | 14:11 |
| KotCzarny | yes | 14:11 |
| ceene | Processor: ARMv7 Processor rev 3 (v7l) | 14:11 |
| ceene | shouldn't it say ARMv8 then? | 14:11 |
| KotCzarny | nope | 14:11 |
| ceene | oh | 14:11 |
| KotCzarny | its different thing | 14:11 |
| KotCzarny | cortex-a8 is armv7 | 14:12 |
| ceene | i hate all those confusing names | 14:12 |
| KotCzarny | marketing, always an evil thing | 14:12 |
| KotCzarny | but mind you, if you compile with thumb, binary wont run on stock kernel | 14:13 |
| KotCzarny | (needs cssu or power kernel) | 14:13 |
| Wizzup | 12:51 < KotCzarny> no nfsd in default cssu kernel? | 14:13 |
| Wizzup | use sshfs? | 14:14 |
| ceene | i always run latest power kernel | 14:14 |
| KotCzarny | wizzup: can you turn off encryption with sshfs? | 14:14 |
| KotCzarny | ceene: just a warning if you ever compile extras app | 14:14 |
| Wizzup | KotCzarny: yes, you can pick a none encryption. | 14:16 |
| Wizzup | Do you see the encryption as a problem? | 14:16 |
| Wizzup | I don't think it'll matter much unless you're sending a *LOT* of data and have a deadline | 14:16 |
| KotCzarny | wizzup, cpu hog | 14:18 |
| KotCzarny | and unneeded when connecting via usb cable | 14:18 |
| * Wizzup hates nfs | 14:23 | |
| KotCzarny | why? | 14:24 |
| Wizzup | KotCzarny: the stupid security model (it had/has), the fact that you usually need root for it, and I think there are much nicer solutions out there | 14:27 |
| Wizzup | sshfs being just one of them | 14:27 |
| Wizzup | Could also use 9P | 14:27 |
| KotCzarny | yeah, it came from time when rsh was password less | 14:28 |
| KotCzarny | :) | 14:28 |
| KotCzarny | but on secure network it's pretty nice | 14:28 |
| kerio | i'm pretty sure that sshfs is even less posixy than nfs | 14:30 |
| Wizzup | What does that have to do with POSIX? | 14:34 |
| BCMM | don't you need root for sshfs too? i thought it's just hidden behind the SUID /usr/bin/fusermount binary | 14:34 |
| Wizzup | BCMM: no, not at all | 14:35 |
| Wizzup | You interface with /dev/fuse | 14:35 |
| Wizzup | although, yes, fusermount is suid | 14:35 |
| BCMM | well, sshfs doesn't work for me if i take the SUID bit off fusermount :) | 14:38 |
| KotCzarny | what a surprise | 14:39 |
| KotCzarny | :) | 14:39 |
| Wizzup | BCMM: What you're stating is that using "su" also always "requires" root | 14:39 |
| Wizzup | Where the fact is that I, as non root user, can invoke su. | 14:39 |
| Wizzup | The same is true for FUSE programs. | 14:39 |
| Wizzup | I don't need to be root to use/invoke them. | 14:39 |
| Wizzup | I'm not sure if the fallacy is intentional | 14:39 |
| BCMM | fair enough. i suppose what i'm wondering is, is there a reason one couldn't have a similar system for nfs? | 14:40 |
| BCMM | in which a bit of SUID userspace lets a user set up an NFS mount while making sure that user doesn't put the mount anywhere he shouldn't be allowed to and so on | 14:40 |
| KotCzarny | i wonder if one could sshfs mount over /usr/bin even with suid (or it has some protection) | 14:40 |
| BCMM | or do non-FUSE filesystems have some inherent danger that makes it impossible to set it up like that | 14:40 |
| *** red723 has joined #maemo | 14:43 | |
| Wizzup | KotCzarny: or course not | 14:43 |
| Wizzup | KotCzarny: you need to own your mountpoint | 14:43 |
| Wizzup | BCMM: you can probably implement nfs in userspace, I guess | 14:43 |
| BCMM | that's not what i meant | 14:43 |
| Wizzup | on my university they used this (root-only nfs) as some kind of security | 14:43 |
| *** LjL has joined #maemo | 14:44 | |
| Wizzup | of course, taking out the cable, plugging in the cable in your laptop, spoofing mac was a trivial way to access all the data/files | 14:44 |
| KotCzarny | yup | 14:44 |
| BCMM | it's that it seems, to me, like the reason you can sshfs as a normal user isn't that the driver runs as a user so much as that there is a SUID binary which will do the root stuff for you and make sure you can't do bad things | 14:45 |
| Wizzup | well, mount is suid too | 14:45 |
| BCMM | and i'm wondering whether that is inherently impossible with a kernel-mode filesystem driver, and why | 14:45 |
| Wizzup | I mean, you can write some suid command that does what mount does, without any checks. | 14:45 |
| Wizzup | but the example I just gave is already a reason it is probably not allowed: many people rely on it (stupidly) for security | 14:46 |
| KotCzarny | sense of security is worse than insecurity | 14:47 |

| Maxdamantus | 23:43:35 < Wizzup> BCMM: you can probably implement nfs in userspace, I guess | 15:48 |
| Maxdamantus | I think traditionally, they also require that you connect from a port under 1024. | 15:48 |
| KotCzarny | which is weak security measure | 15:48 |
| Wizzup | Maxdamantus: yes, but I was not sure about that :) | 15:49 |
| KotCzarny | but doable with fusermount suid | 15:49 |
| Maxdamantus | It's not weak if you have complete control over the network. | 15:49 |
| Wizzup | Maxdamantus: generally you don | 15:49 |
| Wizzup | 't though | 15:49 |
| Wizzup | as I demonstrated above | 15:49 |
| KotCzarny | maxd: see ethernet cable example above | 15:49 |
| Maxdamantus | if you can take out a network cable and plug it into your own device and use it, you don't. | 15:49 |
| Wizzup | :) | 15:49 |
| KotCzarny | i remember doing such tricks in my school | 15:50 |
| KotCzarny | fun times | 15:50 |
| KotCzarny | rootfs was nfs mounted | 15:50 |
| KotCzarny | and it was as easy as booting your own os from usb or laptop | 15:50 |
| KotCzarny | or even floppy | 15:50 |
| KotCzarny | (those were the times when kernel could fit there | 15:51 |
| Wizzup | KotCzarny: tried ARP poisoning? | 15:52 |
| Wizzup | That would literally kill all machines | 15:52 |
| KotCzarny | arp was set statically | 15:53 |
| KotCzarny | on server | 15:53 |
| KotCzarny | not that it prevented me booting my lappy | 15:53 |
| KotCzarny | :) | 15:53 |
| KotCzarny | and accessing network | 15:53 |
| KotCzarny | and i was friends with sysadmin there, so it was fun not cracking | 15:54 |
| KotCzarny | i think the only way to be secure would be vpn for each machine (with secure key stored in bios and inaccessible for reading, only for signing | 15:55 |
| Wizzup | kerberos does this | 15:57 |
| Wizzup | more or less | 15:57 |
| KotCzarny | hmm | 16:02 |
| KotCzarny | is there some virtual mass storage device for linux? | 16:02 |
| Maxdamantus | What do you mean? | 16:02 |
| Maxdamantus | A device you can serve with g_file_storage? | 16:02 |
| Maxdamantus | You can serve any file with that. | 16:02 |
| KotCzarny | more like file | 16:02 |
| KotCzarny | can g_file_storage work with g_ether? | 16:03 |
| Maxdamantus | No. | 16:03 |
| KotCzarny | is there any composite driver for n900? | 16:03 |
| KotCzarny | what i'm after is to server MyDocs via tinysmb and provide minimal autorun for windows | 16:04 |
| KotCzarny | (to configure usb0 interface on windows and mount folder automatically) | 16:05 |
| KotCzarny | hmm, for the former i just need little dhcpd | 16:05 |
| KotCzarny | still, need the latter too | 16:05 |
| Maxdamantus | You could serve a fuse-backed filesystem that detects a particular write pattern | 16:07 |
| Maxdamantus | and uses that to trigger the unloading of g_file_storage and loading of g_ether. | 16:07 |
| *** ArGGu^^ has quit IRC | 16:08 | |
| *** ArGGu^^ has joined #maemo | 16:09 | |
| Maxdamantus | (so you include a program/script that tries to write a particular message somewhere to the virtualised filesystem, the fuse code notices that write and triggers the g_ether loading) | 16:09 |
| Maxdamantus | (the program/script will also configure the network once it sees the USB ethernet device) | 16:10 |
| * Maxdamantus sleeps. | 16:10 | |
| Maxdamantus | on a related note, you can sometimes hack devices like TVs using similar mechanisms. | 16:12 |
| Maxdamantus | device reads file from drive, checks its type, then rereads it to run it knowing that it's a safe type. | 16:13 |
| Maxdamantus | can obviously simulate a drive that returns something else the second time. | 16:14 |

| Wizzup | Pali: yes, I realised @ /proc, I was in sysfs but did not manage (yet) | 21:19 |
| Wizzup | Okay, I get this when I probe it: http://sprunge.us/DCYF | 21:19 |
| Wizzup | (when I probe nokia_modem) | 21:19 |
| Wizzup | P.s. Very happy with your kernel branch | 21:19 |
| Wizzup | I'm slowly just trying to get each item to work | 21:19 |
| Pali | are you using my git branch? | 21:19 |
| Wizzup | Yes | 21:19 |
| Pali | or upstream? | 21:19 |
| Wizzup | Your branch | 21:19 |
| Pali | ok | 21:19 |
| Wizzup | v4.1-rc4-n900 | 21:20 |
| freemangordon | Wizzup: try newer | 21:20 |
| Wizzup | There is a newer one? | 21:20 |
| freemangordon | nokia-modem is upstreamed iirc | 21:20 |
| Wizzup | right, it is, in 4.1 | 21:20 |
| Wizzup | -rc1 | 21:20 |
| Wizzup | this is Pali's "latest" at least | 21:20 |
| freemangordon | https://github.com/pali/linux-n900/tree/v4.2-rc2-n900 | 21:21 |
| Wizzup | I will give 4.3 a try later, right now I wanted a decent defconfig and just to see if I can things to work | 21:21 |
| Pali | Wizzup: try 4.2-rc2-n900 | 21:21 |
| Wizzup | freemangordon: ... hmm .. I'm an idiot :) | 21:21 |
| freemangordon | if you say so :P | 21:21 |
| Wizzup | Ok - will try that soon! | 21:21 |
| Pali | and maybe you can try to revert commit 1bb03c60d30515e590054007e64525c428840120 | 21:21 |
| Pali | at least I have reverted it in my local copy (not pushed) | 21:21 |
| Pali | do not remember why | 21:21 |
| *** shentey has joined #maemo | 21:21 | |
| kerio | can you use linux 4 with the current maemo userland? | 21:21 |
| Wizzup | That is a lot of good info. | 21:22 |
| Wizzup | kerio: doubt it | 21:22 |
| freemangordon | kerio: I see no reason why not | 21:22 |
| kerio | Pali: -bootimg pls | 21:22 |
| freemangordon | Wizzup: the last i've tried was 3.19 iirc | 21:22 |
| Pali | kerio: compile yourself | 21:22 |
| kerio | nuoooo :c | 21:22 |
| Wizzup | freemangordon: ok | 21:22 |
| Wizzup | Anyway, once I get UMTS, calls and host mode to work the real fun starts | 21:23 |
| freemangordon | Wizzup: http://talk.maemo.org/showpost.php?p=1459970&postcount=142 | 21:23 |
| Wizzup | freemangordon: interesting | 21:23 |
| Wizzup | I guess that was pali's? | 21:23 |
| Wizzup | (since powervr doesn't work with mainline, afaik) | 21:23 |
| Pali | Wizzup: reverting that commit is needed for sscd maemo daemon to work | 21:24 |
| freemangordon | unfortunately lately I have no time to continue playing with it, hopefully will have soon | 21:24 |
| Wizzup | Pali: I see, I don't boot to maemo though | 21:24 |
| Wizzup | freemangordon: nice :) | 21:24 |
| freemangordon | Wizzup: yes, Pali's branch | 21:24 |
| Pali | and if you do not want to use maemo userspace, do not revert that commit | 21:24 |
| Pali | plus look at param nokia_modem.pm | 21:24 |
| Pali | you need to switch it to make and export gpios for turning on/off modem | 21:25 |
| Wizzup | Where do I find a .pm file? (sorry for being a noob) | 21:25 |
| Pali | it is not file | 21:25 |
| Pali | it is parameter | 21:25 |
| Wizzup | oh, I see | 21:25 |
| Wizzup | I thought turning on the modem was done using ofono | 21:25 |
| Pali | modinfo nokia_modem.ko | 21:25 |
| Wizzup | ack | 21:25 |
| Wizzup | TMYK :) | 21:25 |
| Wizzup | (I did not know about modinfo) | 21:25 |
| Pali | see /proc/cmdline | 21:25 |
| Wizzup | Back in a bit. :) | 21:25 |
| Pali | that set nokia_modem param needed for maemo/sscd | 21:26 |
| Pali | and you need to overwrite it | 21:26 |
| Wizzup | Ok, I will once I have the device. I will be home in 60 minutes and then I can retry it | 21:26 |
| freemangordon | Pali: hmm, seems I have done most of the jabber ui RE work | 21:28 |
| freemangordon | :) | 21:28 |
| freemangordon | I just need to gather the pieces | 21:28 |
| Wizzup | freemangordon: did you make many changes to maemo to get that kernel to boot? | 21:30 |
| Wizzup | slash work | 21:30 |
| freemangordon | Wizzup: sure, but better ask Pali | 21:30 |
| freemangordon | he has some scripts alreay in place | 21:30 |
| Wizzup | I'm not too interested in maemo right now, in combination with mainline kernel | 21:30 |
| freemangordon | ~pali | 21:30 |
| infobot | hmm... pali is http://atrey.karlin.mff.cuni.cz/~pali/ | 21:30 |
| Wizzup | Just wondering | 21:30 |
| freemangordon | hmm, unfortunately they are missing from the page | 21:31 |
| Wizzup | No problem | 21:31 |
| Wizzup | I'm trying to get gentoo to work, and I'm trying to find a mobile ui for it | 21:32 |
| freemangordon | Pali: where were those scripts that copy maemo to uSD? | 21:32 |
| Wizzup | so I'm quite alright for now | 21:32 |
| Wizzup | mostly I want to see if I can get the modem to work first | 21:32 |
| freemangordon | Wizzup: modem works just fine, in data mode ofc | 21:32 |
| Wizzup | doesn't that require ofono as well | 21:32 |
| Wizzup | I mean, like I said, the module doesnt probe yet | 21:33 |
| Wizzup | for me | 21:33 |
| freemangordon | you need nokia PA modules for voice | 21:33 |
| Wizzup | I will try it soon | 21:33 |
| Wizzup | I have it | 21:33 |
| freemangordon | yep, it requires ofono | 21:33 |
| freemangordon | you have nokia PA modules? | 21:33 |
| freemangordon | are you sure? | 21:33 |
| Wizzup | Oh, no. No. I don't | 21:33 |
| Wizzup | I misread. | 21:33 |
| freemangordon | Wizzup: we have 2 of 3 REed | 21:34 |
| Wizzup | Any info on this? I mean, mailing list threads that I can read | 21:34 |
| Wizzup | ah... cool | 21:34 |
| freemangordon | the last and the most interesting (nokia-voice) is still not. and it is not a single man task | 21:34 |
| Wizzup | I have some RE knowledge | 21:34 |
| Wizzup | (not a lot of time in these two weeks, but later on perhaps) | 21:35 |
| freemangordon | Wizzup: https://notabug.org/freemangordon/pulseaudio-nokia | 21:36 |
| freemangordon | Wizzup: branch fremantle | 21:37 |
| freemangordon | Wizzup: if you want to contribute to nokia-voice module REing, I'll continue my work on it. | 21:38 |
| freemangordon | https://notabug.org/freemangordon/pulseaudio-nokia/src/fremantle/src/voice | 21:39 |
| Wizzup | (I'm looking at your links) | 21:42 |
| freemangordon | ok | 21:42 |
| freemangordon | Wizzup: most of he code in voice module exists in meego nokia-voice, which is open-sourced | 21:43 |
| Wizzup | so this is a decompile, and now we have to rework the code? | 21:43 |
| freemangordon | https://github.com/nemomobile/pulseaudio-modules-nemo/tree/master/src/voice | 21:44 |
| freemangordon | Wizzup: what is a "decompile"? | 21:44 |
| freemangordon | Wizzup: "record" and "music" modules are fully REed and functioning | 21:44 |
| Wizzup | alright | 21:44 |
| Wizzup | https://notabug.org/freemangordon/pulseaudio-nokia/src/fremantle/src/voice/module-voice-userdata.h | 21:44 |
| Wizzup | I thought that this was decompiled somehow, at least, that seems to make sense | 21:45 |
| Wizzup | because of int field_244; | 21:45 |
| freemangordon | ah, yes | 21:45 |
| freemangordon | it is a QIP | 21:45 |
| freemangordon | *WIP | 21:45 |
| Wizzup | I understood | 21:45 |
| freemangordon | unfinished, obviously :) | 21:45 |
| freemangordon | REing that structure is the most demanding task | 21:46 |
| freemangordon | and it is far from being done | 21:47 |
| KotCzarny | hmm, does it work when compiled after decompilation? | 21:47 |
| Wizzup | I will need some time to get some context, etc. I've mostly used maemo, not done that much development on/with maemo | 21:48 |
| freemangordon | KotCzarny: never tried it | 21:48 |
| Wizzup | KotCzarny: would not be too surprised, but yeah | 21:48 |
| freemangordon | KotCzarny: the "working" modules are not a simple IDA decompile | 21:48 |
| KotCzarny | few times i've tried decompiling things they broke after recompilation | 21:48 |
| Wizzup | freemangordon: so quite some of the source is open sourced later on in meego/nemo? | 21:48 |
| freemangordon | Wizzup: actually I'll be surprised if it even manages to compile | 21:48 |
| Wizzup | in the one you linked https://github.com/nemomobile/pulseaudio-modules-nemo/tree/master/src/voice | 21:48 |
| freemangordon | Wizzup: yes, but it is similar, not same | 21:49 |
| Wizzup | I see | 21:49 |
| freemangordon | lots of stuff being moved to colsed blobs | 21:49 |
| freemangordon | *closed | 21:49 |
| Wizzup | I think I'll go home soon (going to jump on the bike soon) so I'll be back later | 21:49 |
| Wizzup | freemangordon: ah | 21:49 |
| KotCzarny | also, having a current kernel that works with fremantle would be nice for dualbooting | 21:49 |
| Wizzup | Back later | 21:52 |
